CLASSIFICATION
Many classi cations other than REVAS have been devel-
115,116
oped concerning recurrences,
but they have not been widely used. At the consensus meeting held in 1998 we decided to use both the previously reported CEAP clas-
1
si cation and a speci c REVAS classi cation.
 is new classi cation was intended to serve everyday clinical prac­tice as well as research studies into epidemiology, clinical status, and treatment of recurrent varicose veins. Asur­vey was undertaken in order to test its intraobserver and
84
interobserver reproducibility.
 e conclusion of this study was that intraobserver reproducibility is quite sat­isfactory, and making slight changes in the answers to one question, might increase interobserver reproducibility. However, the fact that interobserver reproducibility was less than intraobserver reproducibility re ects conditions of real life, and especially interobserver di erences. Such interobserver di erences may arise from interobserver technical di erences, but this  nding emphasizes the need for validating a duplex scanning protocol and a standard­izing duplex scan reports (see below, “Investigations”)
 e REVAS classi cation (Table 30.1) includes six items: T is for topographic sites of REVAS; S for sources of re ux; R for degree of re ux ; N for nature of sources ( Nss for same site of previous surgery, and Nds for di erent sites); P for contribution from a persistent incompetent saphenous trunk; and F for possible contributory factors ( Fg for general and Fs for speci c factors).
This classification has been used only for REVAS, but it might be used for any kind of recurrence after
operative treatment in combination with the CEAP classification. Nevertheless it looks that a new classifi­cation—PREVAIT classification—not yet drawn up might be a bettertool.
DIAGNOSIS
MODES OF PRESENTATION
Patients who have previous nonconservative treatment may consult their physicians for various reasons: unsightly recurrent varicose veins or related emotional problems that are especially common in female patients, discomfort (in other words venous-related symptoms), appearance of cuta- neous or subcutaneous changes, concerns about the health risk related to their veins, or limitation of activity. Also PREVAIT may be found at routine follow-up.
MEDICAL HISTORY
Family and Personal History
Family history of varicose veins and personal history includ­ing pregnancies, hormone therapy, super cial thrombophle­bitis, deep vein thrombosis, and so forth, should be recorded.
Previous Treatment
 e date of previous treatment(s) for varicose veins must be reported, as well as the age of the patient at the time of opera­tive treatment, occurrence of new pregnancies a er initial

PHYSICAL EXAMINATION
Presence and intensity of the various vein-related symptoms have to be noted:pain, throbbing, heaviness, itching, feel­ing of swelling, night cramps, heat or burning sensations or restlesslegs.
Some data are available on patients presenting
PREVAIT, including severity of leg symptoms and clinical

Many investigations have been used in the past to assess REVAS. At the moment there is a large consensus for rec­ommending DS in all cases of PREVAIT.  is investigation provides anatomical and hemodynamic data including
•
 e topographical sites of recurrence that can be mapped,
•
 e possible sources of re ux from the deep venous
system to the super cial (Figures30.2 and30.3),
•
 e intensity or degree of re ux,and
•
 e nature of sources keeping in mind that causes have
to be classi ed di erently if recurrence occurs in a site previously treated ornot.

In few select cases ascending venography in three­dimensional imaging may give complementary valuable information. PREVAIT related to re uxive pelvic varices is better investigated by selective descending phlebography ( Figure30.4 ). Other investigations such as air plethysmog­raphy and ambulatory pressure measurement may be useful for research studies but not for daily practice.

Compression
Compression in varicose veins is frequently recommended and improves both symptoms and signs, but it does not cure the disease.
D r u g s
In varicose veins phleboactive drugs are prescribed mainly to improve edema and symptoms.  e most commonly used are  avonoids, but othersexist.
Operative Procedures
Operative procedures share the same goals:(1)to supress re ux from deep to super cial systems when present, (2)to supress varices, and (3)in some speci c cases to suppress deep vein abnormality to prevent new recurrences.
 e  nal goals are multiple: decrease the ambulatory
venous pressure, prevent worsening of chronic venous
disorders, avoid further recurrences and of course improve patients’ in terms of cosmetic appearance, symptoms andsigns.
Ultrasound-Guided Sclerotherapy
Sclerotherapy has been used for a very long time for treating REVAS, but ultrasound-guided sclerotherapy (USGS) has improved the e cacy. Di erent protocols have been used, but no comparative study with other opera­tive treatment is available. Recently polidocanol foam has entered the ring, but currently no consensus exists on the techniques, doses, concentrations, or sclerosing agents for PREVAIT.
Nevertheless one of the main advantages of sclero­therapy with or without foam is that the process is cheap, simple, less invasive, and repeatable. USGFS can both oblit­erate the re uxive varices and suppress most of the leak points between deep and super cial venous system includ­ing pelvic, SFJ or SPJ, and perforator re ux as well as varices not connected to the deep venoussystem
Open Surgery
Procedures can be classi ed into three groups according to their objective, and should be used in combination.

the SFJ or SPJ, if the site has previously been operated and depending on the extent of postoperative  brosis, redo surgery may be di cult. It is recommended that the deep vein be approached  rst in order to avoid dissection of scar tissues, lymphatic nodes, and cavernoma.  e last does not need to be ablated. Flush ligation of the stump is then per­formed and can be completed by patch interposition at the SFJ for avoiding new recurrence.

Nevertheless, 22.6% of patients had di use varices, with a new site of incompetence between the deep and super cial systems.

has compared the results at 5years of two nonrandomized groups with and without patch, respectively group 1 and 2 in a prospective study. All patients had recurrent SFJ incompetence. At 5-year follow-up, recurrent thigh vari­cosities were observed in 58% of group 2 versus 26% of group1.

Pelvic and Gonadal Vein Embolization
At 6-month follow-up, 90% of 215 patients treated by embolization of gonadal and pelvic veins were signi cantly improved in both signs and symptoms, but relief of pelvic pain or lower limb symptoms or signs were not evaluated separately ( Figure30.5 ).

INDICATIONS
Indications for treating patients with recurrent varices.
Patients can be roughly divided into two groups:
1. Patients complaining of symptoms or aesthetic concerns, or presenting with signs of chronic venous disease (C
–C 6 ). In all cases these patients need to be
2
investigatedbyDS.
2. Subjects attending a routine follow-up.  e decision whether to undertake DS or not depends on the presenting complaint and physical  ndings. In practice, DS is almost alwaysdone.
A S Y M P T O M A T I C
When hemodynamic or anatomic abnormalities are found in asymptomatic patients without severe signs who are not concerned by their minor varices as cosmetic problems the decision to treat depends of the severity of the noninvasive  ndings. In all cases follow-up is required, because abnor­mal DS  ndings precede symptoms andsigns.

In symptomatic patients presenting with recurrent varices and hemodynamic anomalies, operative treatment must be considered.
Although there is no randomized controlled trial com­paring redo surgery to chemical ablation, there is a con­sensus for treating recurrences with USGFS as  rst-line

for reasons discussed above. In very few cases when duplex scanning reveals an intact and large incompe­tent saphenous stump at the SFJ or SPJ with a massive re ux  lling the varicose network, redo surgery at the junction should be considered in combination withUSGFS.

Currently there is no quality-of-life tool that is su ­ciently sensitive to detect clinically signi cant changes and ful ll all of the above criteria; and a number of di erent generic health care questionnaires have been developed. In recent years the most popular tools for the measurement of venous disease have included the Nottingham Health Pro le (NHP), the EuroQol (EQ-5D), and the short form 36 (SF36).  e EQ-5D and SF36 are also validated in other major languages and are widely accepted internationally. Although applicable across a spectrum of disorders to allow a comparison of health-related quality of life across popula­tions of patients with di erent diseases, these generic tools are frequently insu ciently sensitive to detect clinically sig­ni cant changes in speci c disease processes over time. For this reason, disease-speci c quality-of-life tools have been designed, in order to be sensitive to these key dimensions in quality of life that are a ected by the disease. In 2007 the American Venous Forum (AVF) published a consensus of recommended reporting standards speci c to endove­nous ablation of varicose veins, which supported the use of a combination of disease-speci c and generic quality-of-life questionnaires.

Q U A L I T Y O F  L I F E
Health is de ned by the World Health Organization as “a state of complete physical, mental and social well being and not merely the absence of disease”; and measuring health and improving quality of life is of major importance throughout all branches of medicine. In 1997 Beattie etal. suggested that the ideal quality-of-life measure shouldbe:
•
Equally applicable to any disease process or outcome,
•
Equally applicable across all levels of illness and degrees
of invalidity,and
MEASUREMENT OF OUTCOMES
In developing an outcome measure, the concepts of validity, reliability, and responsiveness arevital.
12
Validity is the extent to which a questionnaire measures what is intended.  is is frequently evaluated by compar­ing a new measure with an established one (criterion valid­ity). In the absence of a gold standard, a construct’s validity can be measured; this allows comparison of a new tool with objective or clinical  ndings.
