Phlebectomy
Mikel Sadek and Lowell S. Kabnick
39.1 INTRODUCTION
The current phlebectomy technique was rst described by Robert Muller, a dermatology-trained phlebologist from Neuchâtel, Switzerland, who reinvented and rened the technique that we know today as ambulatory phlebec­tomy. Muller’s technique was rst presented in 1967 to the French Society of Phlebology, and in 1968 to the Interna­tional Congress of Phlebology, and it was poorly received. With time and experience, the phlebectomy technique has become more widely adopted and now represents the stan­dard treatment for reuxing venous tributaries [1–3].
Today, the procedure is performed typically under local anesthesia in an ambulatory setting. Briey, a small hook­like instrument, together with ne clamps, is employed to extract the varices using small (~1- to 2-mm) incisions. At completion of the procedure, a dry sterile compression dressing or a compression hose is applied to the limb.
This chapter will cover the indications, technique, peri-procedural care, and possible complications associ­ated with ambulatory phlebectomy. For the reader to best gain expertise and to visualize technical aspects of the pro­cedure, the authors suggest not only reading this chapter but also seeking out an expert in the eld of phlebectomy to observe the procedure.
39.2 DEFINITION OF AMBULATORY
PHLEBECTOMY
The term “ambulatory phlebectomy,” coined by Dr. Muller, refers to the technique in which varicose veins are extracted in an outpatient setting under local anesthesia using small punctures and hooks. Ambulatory phlebectomy, stab avul­sion, stab phlebectomy, microphlebectomy, and microex­traction are synonymous terms that dene this technique. The Current Procedural Terminology code book of the American Medical Association lists three codes for the bill­ing of the procedure: (1) 37765, stab phlebectomy of vari­cose veins, one extremity, 10–20 stab incisions; (2) 37766, stab phlebectomy of varicose veins, one extremity, more than 20 incisions; and (3) 37799, for fewer than 10 inci­sions [4]. When discussing the procedure with a patient, we recommended that the terms “ambulatory phlebectomy”
or “microphlebectomy” be used, because they are often more acceptable to the patient, as compared to “stab avul­sion” or “stab phlebectomy.”
39.3 DIAGNOSTIC METHODS AND INDICATIONS
39.3.1 Diagnostic methods
A complete history and physical examination should be performed, with attention being paid to the anatomic dis­tribution of concern, the symptom prole, including the HASTI symptoms (heaviness, achiness, swelling, throb­bing and itching), and other patient-reported metrics [5]. A history of supercial phlebitis or varicose vein bleeding should be obtained. The practitioner should also assess for a history of venous thromboembolic disease, hyper­coagulable states, prior venous procedures, and the use of antiplatelet or anticoagulant medications. A family history can also help to inform long-term prognosis. On exam, the focus should be on the clinical presentation, and this may be categorized using the CEAP and the venous clinical severity score (VCSS) classications [6,7]. One should also pay attention to any evidence of vascular malformations or other congenital pathologies such as Klippel–Trenaunay or Parkes–Weber syndromes. An arterial exam/pulse exam should be performed, and an ankle-brachial index (ABI) of greater than 0.8 is a reasonable guideline for deeming that arterial perfusion is adequate. It is worth emphasiz­ing that a normal ABI does not entirely exclude arterial pathology. A falsely elevated ABI can be seen in diabetic patients, elderly patients, and patients with renal disease, due to incompressible calcied vessels.
Regarding imaging studies, a venous duplex ultrasound should be performed in all cases. It is often benecial to identify the presence of reuxing venous tributaries, as well as their source from truncal veins or perforators. As with reuxing truncal veins, reuxing tributaries are dened as having a reux time of greater than 500 ms. More advanced axial imaging (i.e., CT or MR venography) and direct venography are typically not required unless adjunc­tive procedures are indicated. At the time of the procedure, transillumination is very helpful for tracing out the target

varicose veins or reticular veins and to better visualize varicose veins associated with overlying telangiectasias. Examples of transilluminating devices include the Veinlite (TransLite, Sugar Land, TX) and VeinViewer (Luminetx, Memphis, TN).
39.3.2 Indications
Indications for ambulatory phlebectomy vary depending on the skill set of the individual practitioner. Patients of all ages are candidates for phlebectomy, and this holds true especially for the octogenarian and the elderly in general, where venous procedures have been shown to improve both clinical and patient-reported outcomes [8]. Ambula­tory phlebectomy may be medically or cosmetically indi­cated, and it may be performed as a stand-alone procedure or in conjunction with another procedure (e.g. endovenous ablation).
Varicose veins of any size and in any location are can­didates for ambulatory phlebectomy. These include the epifascial supercial accessory great saphenous vein, super­cial truncal veins in general, tributaries, and reticular veins. Also appropriate for ambulatory phlebectomy are regional venous networks, including accessory saphenous veins of the thigh, pudendal veins, perineal veins, reticu­lar veins of the lateral subdermic plexus and the popliteal fossa, hand and foot veins [9, 10]. Dilated veins in other parts of the body, including the periorbital, abdominal, and chest areas, as well as medial thigh perforators and small lateral perforators, may be treated successfully using this technique [11].
Areas requiring additional attention for ambulatory phlebectomy are the knee, tibial, and foot areas, where the veins are tethered by connective tissue, making their removal somewhat arduous. Other areas of caution are the peripheral great saphenous vein in the saphenous nerve distribution and the peripheral small saphenous vein in the sural nerve distribution. Lateral leg varicosities overlying the bular head are in the region of the peroneal nerve and should be approached with caution, and the same applies to many areas of the hands and feet. Lastly, care should be taken in the temporal forehead region, given that the tor­tuous temporal artery is sometimes misconstrued for being a varicose vein, and a phlebectomy procedure should be avoided given the potential risks for bleeding or ischemia.
39.4 TREATMENT STRATEGIES
thigh circumex vein; however, many aws were noted in the study [12]. The two treatment methods are integral to delivering complete venous care, and the practitioner must know both procedures.
39.4.1 Delayed versus simultaneous procedures
There remains debate over whether ambulatory phlebec­tomy should be performed simultaneously with truncal vein ablation or if it should be staged. Some insurance carriers, for example, will require that ablation of the associated truncal vein be performed rst and that adjunctive phlebec­tomy be performed in a staged fashion after a prescribed interval, and this trend has increased steadily over time. Historically, the complete removal of any varicosities at the same time as great saphenous vein treatment has been dogma. In the early twentieth century, Homans and Mayo published papers stating that the complete removal of vari­cosities was encouraged to prevent recurrence [13,14]. The current scientic literature regarding the timing of varicos­ity treatment after interruption of truncal reux is scant; however, a review of the literature reveals that simultane­ous treatment of varicosities leads to higher patient satis­faction, early gains in quality of life, and a reduced need for further procedures [15–17]. The nal decision on treatment strategy should rest with the clinician and the patient, as both delayed and simultaneous procedure pathways offer good outcomes [15–17].
39.4.2 Benefits of ambulatory phlebectomy
Ambulatory phlebectomy is an effective, cosmetic and cost-efcient way to remove varicose veins. Improvements in anesthetic technique, namely the use of tumescent anes­thesia, have limited the amount of pain both intraopera­tively and postoperatively. Patients can return to daily activities after the procedure. Due to the paucity of reported complications, the procedure is considered to be safe, but there are some nuances to be aware of. Post-procedural bleeding can occur rarely, and appropriate return precau­tions should be given to the patient. Blistering may occur at the sites of Steri-Strip application due to shear stress on the skin resulting from postprocedural edema. Mild pain and ecchymosis are to be expected, and the patient should be counseled accordingly [18–20]. Long-term results, even if presumed excellent, have not been well studied to date.
Accepted treatment options in phlebology include com­pression therapy, sclerotherapy, ambulatory phlebectomy, endovenous thermal ablation, and topical laser. Each treat­ment modality has its advantages and limitations; however, there is signicant overlap.
Sclerotherapy is the closest alternative treatment strategy to ambulatory phlebectomy. At present, there is still a debate as to which is better and a paucity of evi­dence-based literature to support the superiority of either procedure. A single randomized controlled trial by de Roos et al. demonstrated the superiority of ambulatory phlebec­tomy over sclerotherapy for the treatment of the anterior
39.4.3 Contraindications
There are a limited number of contraindications to ambu­latory phlebectomy. The following conditions should be considered relative contraindications: infectious dermati­tis or cellulitis in surrounding areas, severe arterial insuf­ciency, serious illness, and pregnancy. Although the use of anticoagulation has traditionally been considered a contraindication, ambulatory phlebectomy can in fact be performed safely in patients on anticoagulation, including with the use of warfarin and direct oral anticoagulants (DOACs) [21].
39.4 Treatment strategies 397

39.4.4 Technique
39.4.4.1 Preoperative preparation
All target veins should be traced while the patient is standing, as they may be difcult or impossible to identify while recumbent. Surgical markers include those using gentian violet–colored solution (e.g., Vismark; Viscot Medical, East Hanover, NJ). The use of a permanent marker to trace the veins should be avoided because of the risk of tattooing. After the patient has been placed in the recumbent position, the vein marks can be adjusted using a transilluminator or an ultrasound if neces­sary. Because veins can reposition, this subsequent adjustment adds to the efcacy and speed of extraction (Figure 39.1) [22].
39.4.4.2 Surgical plan
The timing of ambulatory phlebectomy depends on the nature and type of other venous procedures being performed, and it depends on practitioner preference. When ambulatory phlebectomy is coupled with saphenectomy or endovenous ablation of a truncal vein, there can be a transient increase in endoluminal pressure in the caudally distributed veins, which could result in an increased risk of bleeding. This can be reduced by placing the patient in the Trendelenburg posi­tion. Depending on the physician and patient preferences, procedures can be staged, treating the truncal vein rst, fol­lowed several weeks later by ambulatory phlebectomy. This method allows the existing truncal varicosities to decrease in size and number, potentially reducing the extent of sub­sequent procedures. Both operative strategies have been shown to be safe and effective [15, 16, 23, 24].
39.4.4.3 Anesthesia
Local anesthesia with or without epinephrine was used his­torically, but most operators now suggest using tumescent anesthesia for ambulatory phlebectomy.
39.4.4.4 Tumescent anesthesia
Tumescent function: adjective. Etymology: Latin tumes­cent-, tumescens, present participle of tumescere to swell up, inchoative of tumere to swell: somewhat swollen < tumescent tissue > [25].
J.A. Klein, a dermatologist, was the rst to describe tumescent anesthesia in 1987 [26]. His method utilized dilute local anesthesia as a way of creating a eld block. Tumes­cent anesthesia exploits the principles of pharmacokinetics to achieve anesthesia of the epidermis, dermis, and subcu­taneous tissues. The subcutaneous inltration of a large vol­ume of dilute, buffered lidocaine and epinephrine causes the targeted tissue to become swollen and rm, or tumescent. Because the subcutaneous tissue is relatively avascular, a large volume of diluted epinephrine injected into this area produces widespread and prolonged vasoconstriction. Vaso­constriction appears to diminish the rate of systemic lido­caine absorption, thus reducing the peak plasma lidocaine concentration, reducing potential toxicity, and permitting a much larger dose of lidocaine to be administered [26–29].
According to Klein,
In fact tumescent technique permits safe lidocaine dosage of at least 35 mg/kg of body weight and provides effective local anesthesia for as long as ten hours. The widely accepted 5–7 mg/kg safe maximum dose for lidocaine with epinephrine when adminis­tered subcutaneously has never been substantiated by a published scientic study. [29]

39.1 The circle and dotted line tracing the vein were drawn
with the patient in an erect position (blue arrows). The straight line was drawn with the patient in a recumbent position (red arrows).
Klein and others observed that the pharmacokinetics of dilute lidocaine with epinephrine are different from those of 1%–2% lidocaine. With undiluted lidocaine, a measur­able plasma level appears in 15 minutes and peaks soon after; lidocaine is metabolized in a few hours. Absorption of the tumescent solution is slower, causing peak plasma levels to occur many hours later, and thus the anesthetic effect is longer. Patients receiving large volumes can have plasma levels that peak in 4–14 hours and linger for longer than 24 hours [29].
39.4.5 Procedure for administering
tumescent anesthesia
In 1995, Cohn and coworkers reported using the tumes­cent technique for local anesthesia while performing ambulatory phlebectomy [30]. Three years later, Smith and Goldman reported the use of tumescent anesthesia for ambulatory phlebectomy [31].
The inltration of dilute anesthesia in a perivascu­lar position—epidermal and dermal—serves several pur­poses: (1) the anesthetic effect is long-lasting and sensation returns slowly; (2) with the use of longer needles and dilute solution, fewer needle punctures are needed and less pain upon administration is observed; (3) the tumescent tech­nique causes more compression of the surrounding tissues,
398 Chapter 39 Phlebectomy
https://t.me/med1917
leading to less hematoma and ecchymosis; (4) hydro-dis­section occurs around the vein, facilitating the removal; and (5) reduction of infection, usually limited to the inci­sion site, is a result of the bacteriostatic and bactericidal properties of lidocaine [32].
The methods of delivering and mixing ingredients of tumescent anesthesia vary between operators. A typical solution is as follows: 445 mL of 0.9% saline, 50 mL of 1% lidocaine with 1:100,000 epinephrine, and 5 mL of
8.4% sodium bicarbonate.
Presently, most operators use a regular syringe, a self-lling syringe, or a peristaltic pump to deliver tumes­cent anesthesia. The last two methods facilitate the delivery of higher volumes of tumescent anesthesia. Microcannulas, 22G/25G 7 cm hypodermic, or spinal needles are used for the delivery of the solution.
39.4.6 Procedural equipment
Incisions or punctures can be made with various instru­ments, including hypodermic needles and surgical blades. The most common instruments are 18G needles, number 11 blades, and standard 15-degree ophthalmologic blades (I-KNIFE II Alcon, Fort Worth, TX). After the phlebectomy is completed, 12 × 33-mm adhesive microporous surgical tapes (Steri-Strips 3M, Oakdale, MN) are placed to close the punctures. Occasionally, one may close the surgical sites with interrupted 6-0 or 5-0 nylon sutures when there is signicant bleeding, and sometimes this is benecial at the joints where surgical tape may not adhere as well. If sutures are used, it is important to plan for expeditious suture removal within approximately 1 week in order to ensure the best cosmetic result.
Several different hooks are available for use, varying in size, shape, and sharpness. Commonly used hooks are the Muller, Oesch, Tretbar, Ramelet, Verady, Dortu-Mar­timbeau, and Kabnick hooks [33]. One particular phlebec­tomy instrument is not superior to another. It is important for the clinician to be comfortable with a particular set of hooks, making the selection after trying the gamut.
The clamps used for vein extraction should have a ne tip so that they can grip close to the skin. A serrated face is helpful in maintaining rm traction without slippage. The operator should have at least three ne hemostat clamps available, but ve or more is preferable (Figure 39.2).
39.4.7 Procedure
After the anesthetic has been injected into the perivenous tissues, an incision/puncture (~1–2 mm) is made near the vein (Figure 39.3). Most are oriented vertically, except around the knee, where they should be oriented along the tension lines (Langer lines). A blunt-tip spatula may be inserted into the incision to dissect the dermal fascia, although this is not mandatory (Figure 39.4). It does, how­ever, facilitate a hook to be inserted without interference from surrounding tissues and without enlarging the inci­sion. Once the hook has been inserted, the vein is grasped blindly and extracted through the incision (Figure 39.5a). If the vein is not extracted, the hook is maneuvered with nesse at different angles, repositioning the instrument through the incision until the vein

approaching the vein, he or she should execute the motion while paying attention to the depth. When just the peri­vascular connective tissue is hooked, that tissue is clamped with a hemostat and kept in traction while the hooking maneuver is repeated until a venous loop is exteriorized. The vein is then grasped between clamps and transected with ne scissors (Figure 39.5b and c). Using gentle trac­tion on the hemostat in a “windshield wiper movement,” one end of the varix is teased out of the puncture site. Suc­cessive hemostats are applied to the varix as it is extracted from its position, keeping in mind that the vein will even­tually tear (Figure 39.5d). Very long segments can often be removed through a single puncture site. Once a segment has been extracted, the operator moves along the vein by a roughly equivalent distance to makes another incision, and the process is repeated. Any redundant perivascular tissue exposed out of the puncture site should be trimmed at the skin level. If a small nerve ber is exteriorized, it is likely that the patient will expe­rience an immediate sharp pain and burning sensation. If the nerve ber has not been transected, the operator should reintroduce the nerve ber into the incision and move on to another area to access the vein segment. After the proce­dure, some patients may develop areas of hypoesthesia that in most cases will resolve [18].
The operator is encouraged to remove all parts of the
varix without leaving isolated segments behind to reduce a possible inammatory response from thrombosis of the
the segment extracted and
retained segment. Nevertheless, if most of the segment is removed, the patient should have an excellent result, and residual segments will brose and regress over time. There is rarely need to ligate a vessel except when a per­forator, peripheral foot vessel, hand vessel, or large varix (>1 cm) is exposed (Figure 39.5e). Sometimes ligation may also be performed at the central and most periph­eral aspects of the phlebectomy procedure in order to reduce ecchymosis. Ligation of vessels may improve the early cosmetic result due to less bruising and subsequent staining. the vein, often with an orientation that is perpendicular to the skin, and can be associated with a deep pulling sensation.

After ambulating and once vital signs are stable, the patient can be safely discharged from the facility. Discharge and follow-up recommendations to patient are as follows:
1. On the day of surgery, walk ad libitum.
2. Take acetaminophen or ibuprofen as needed for dis­comfort.

placement.
3. Wear the compression wraps continuously for 24 hours. After 24 hours, remove all of the dressing materials except the adhesive microporous surgical tape. The adhesive surgical tape should be left in place for 10–14 days.
4. Once the dressing is removed, apply the compression stocking(s) (class 2, 30–39 mmHg) for a minimum of 1 week during waking hours. The data for this have var­ied, with some studies showing benet to wearing com­pression, and others failing to show benet [17, 34].
5. May shower after 2 days. There is to be no tub bath­ing or swimming until the adhesive surgical tapes are removed.
6. There is to be no lower body or heavy aerobic exercise for 1 week. Return to activities of daily living as usual.
7. Follow-up is to take place in 2 weeks, 3 months, and 1 year.
phlebectomies [37]. The second was a literature review by Ramelet in 1997 [18]. He reported the complication rates of several different authors. The rates of complica­tions vary widely, with skin blistering being the highest, ranging from 1.3% (1997 Olivencia report) to 20% (1980 Gillet report) [38]. Telangiectatic matting has varied in the different studies from 1.5% to 9.5% in Trauchessec and Vergereau’s report [39]. Some authors have reported tel­angiectatic matting to be as high as 2.4%. However, if we look at current reports, the common complications appear to change in frequency. Regardless, the most common com­plications are development of telangiectasias, 2%; blister­ing, 0.5%; and hyperpigmentation (limited), 0.01%. The most common technical failure is a missed varix, occurring in 0.3% of cases.

39.4.8.1 Complications
Complications arising from ambulatory phlebectomy are quite rare, but can occur, as listed in Table 39.1 [19, 20, 35, 36]. There have been two large retrospective studies looking at the complications of phlebectomy. The rst was a multicenter French study that reviewed 36,000
The proprietary name for the transilluminated powered phlebectomy (TIPP) device is the TriVex System (LeMai­tre Vascular, Inc., Burlington, MA). The development of this device began in 1966, when Greg Spitz, a surgeon,

took an arthroscopic shaver and applied it for the removal of varicose veins. Through many derivations, including transillumination and a delivery method for tumescent anesthesia, the present system was complete. The system contains a modied arthroscopic shaver and a transillu­minator coupled with an irrigator that delivers tumescent anesthesia. The concept was developed to decrease the time for ambulatory phlebectomy. Although there have been many modications, the procedure remains virtually the same. Varicose clusters are transilluminated, anesthe­tized, morcellated, and aspirated (Figure 39.7a and b).
39.6 Conclusion 401
complications can be reduced by dissecting carefully along and parallel to the varicose vein, avoiding lateral movements, and using a lower oscillation frequency and a pulsing technique to allow for proper aspiration [41, 44]. Other encountered complications after TIPP are skin per­foration, nerve injury, deep vein thrombosis, incomplete vein resection, hypertrophic scarring, permanent skin dis­coloration, and wound infection [45].
Traditionally, TIPP has been performed in an operat­ing room under general or regional anesthesia with seda­tion; however, in 2011 Spitz reported his experience with a series of 36 patients treated with TIPP in the ofce setting with good clinical outcomes [46].
Although TIPP is presently utilized, compared with hook microphlebectomy, TIPP has not been proven to be simpler, more cost-effective, less insulting to tissue, or bet­ter cosmetically.
39.6 CONCLUSION
Ambulatory phlebectomy has been adopted as the stan­dard procedure and denitive treatment for the removal of varicose veins. This simple procedure has added a highly acceptable aesthetic results to the medical indi­cation. Preoperative mapping with transillumination accurately identies the location of varicosities. Local or tumescent anesthesia is recommended when performing ambulatory phlebectomy. The above-described procedure, including—1- to 2-mm incisions, hook technique, and compression—results in minimal recovery times and few complications (Figure 39.8 a and b). Ambulatory phlebec­tomy can be staged or performed concurrently with trun­cal ablation. TIPP has been effective in multiple studies in treating varicose veins. Phlebectomy has been superior to sclerotherapy for varicose veins.

39.5.1 Study results
Studies of the TriVex System describe several modica­tions of the procedure to improve patient outcomes. Investigators have often compared manual phlebectomy with TIPP. Most authors indicate that the number of inci­sions is fewer with TIPP and the operating time is faster. Ray-Chaudhuri et al. compared postoperative pain scores, with the results after 14 days being 2.6 (manual) and 1.9 (TIPP), a difference that was not statistically signicant [40]. Cosmetic effect was also equal. In two randomized trials Aremu et al. and Scavée et al. demonstrated no dif­ference in patient cosmetic scores or satisfaction [41, 42]. These conclusions were recognized by Spitz and cowork­ers in their original reported ndings [43]. In addition, the authors agree that TIPP has a signicant learning curve. The learning curve is associated with a higher num­ber of missed veins along with an increased incidence of hematoma and other adverse events. These postoperative
