42.1 Introduction
Soft tissue reconstruction of the lower limb, especially the dis­tal third is one the most challenging areas of reconstruction faced by plastic surgeons. The lack of excess soft tissue in this region limits the local ap option, hence making free tissue transfer as the preferred choice. However, the introduction of the concept of perforator ap by Kroll and Roseneld in 1988 [1] and Koshima and Soeda in 1989 [2], followed by the intro­duction of propeller aps by Hyakusosku in 1991 [3] trans­formed the design of local aps, making them a more reliable option for the lower limb.
The most reliable perforators in the leg arise from the three main arteries: the posterior tibial (PTA), the peroneal (PA), and the anterior tibial (ATA). However, aps based on the per­forators arising from the rst two arteries are the most com­monly used. They can be used for reconstruction of defects in the distal third of the lower extremity, the foot, Achilles ten­don, around the ankle joint including the medial and lateral malleolus, and down to the nonweight-bearing part of the heel [4]. They can also provide coverage for defects in the middle and upper third of the leg and around the knee joint.

Zhang and colleagues [5] in 1983 were the rst to describe harvesting a medial leg cutaneous ap based on the PTA and its cutaneous branches. Venkataramakrishnan et al. [6] avoided sacricing the PTA and reported raising posterior tibial artery perforator (PTAP) based V-Y advancement aps. In a case report by Hallock in 1993 [7], he described the use of a PTAP ap to cover an exposed medial malleolus after rotating the ap 180° which is now known as a propeller ap.
A propeller ap can be dened as a fasciocutaneous ap, completely islanded on a single perforator and designed with two blades of unequal length. The perforator constitutes the pivot point of the ap, which allows it be rotated 90–180°. The long blade of the ap ts into the defect, while the short blade helps closure of part of the donor site [8].
On the other hand, peroneal artery perforator ap was rst described by Donski and Fogdestam in 1983 [9], who raised a fasciocutaneous ap based on the distal cutaneous perfora­tor originating from the peroneal artery about 5–7cm supe­rior to the lateral malleolus to cover the Achilles tendon.
42.2 Anatomy
42.2.1 Posterior Tibial Artery Perforator Flap
A cadaveric study done by Schaverien and Saint-Cyr [10] reported that perforators of PTA were the largest in the leg and were found in three clusters between the soleus and the exor digitorum longus muscles, each being 4–9, 13–18, and 21–26cm from the inter-malleolar line (Fig.42.1a). Each clus­ter contains 23% of PTA perforators, and a perforator was found in each of them in 80% of the cadavers in the study. Multiple musculocutaneous perforators, usually passing through the soleus or gastrocnemius muscles, were also found in all zones of the leg, but were mainly located proximally. Two venae comi­tantes followed each perforator, and in the distal leg they are occasionally connected to the long saphenous vein [11].
The proximal two-thirds of the leg were found to have perforators with the largest caliber which pierce the deep fas-

cia perpendicularly. This was found to be advantageous for the design of a propeller ap as it minimizes the chance of the perforators to kink if twisted [12].
When the PTAP ap is based on an appropriate perfora­tor, its territory can extend from the anterior border of the tibia to the posterior midline, and about 2.5 times this width
The proportion of musculocutaneous to septocutaneous perforators widely varies between studies [17]. For example, Heitmann etal. [18] reported 34% of perforators to be mus­culocutaneous and 66% septocutaneous, while a study done by Yoshimura etal. reported these to be 71% musculocutane­ous and 29% septocutaneous [19].
in terms of proximal to distal extension [13, 14].
42.3 Preoperative Investigation
42.2.2 Peroneal Artery Perforator Flap
PA supplies the posterolateral aspect of the leg through 5±2 musculocutaneous and septocutaneous perforators, making the PA angiosome to extend from the posterior border of the bula medially to the central raphe of Achilles tendon later­ally [15]. These perforators are located at 3–5cm interval, and most of them are found at about 13–18cm superior to the lateral malleolus [10] (Fig. 42.1b). The musculocutane- ous perforators predominate in the proximal leg and come through the soleus or peroneus longus muscles, while the septocutaneous perforators appear distally through the sep­tum between the exor hallucis longus and peroneus brevis [10]. About 5cm above the lateral malleolus, a good-caliber perforator emerges from the PA, penetrates the interosseous membrane then divides into a supercial branch which sup­plies the skin of the lateral supramalleolar ap and a deep descending branch which anastomoses with the anterolateral branches of the anterior tibial artery [16].
Perforators of the PTA and PA can be identied preopera­tively using hand-held Doppler, color Doppler, Duplex ultra­sound, thermal imaging, arteriography, high-resolution computed tomography, or magnetic resonance angiography [8, 20]. These modalities are useful in detecting the ap per­forators, but they cannot provide information about the ap viability.
Hand-held Doppler is a simple useful tool for preopera­tive localization of adequate perforators; however, color Doppler is a more accurate method in terms of providing more data about the internal diameter of perforators [21]. Thermography has now also become an affordable and easy obtainable method for preoperative mapping, intraop­erative decision-making and postoperative monitoring of propeller aps using smartphone-compatible thermal imaging cameras [22]. On the other hand, computed tomography angiography (CTA) is now considered by many studies as the gold standard technique for mapping

the cutaneous vasculature of the lower extremities. It can provide detailed information about the PTA and PA, and the anatomical data of their perforators including the diameter and course. Such data facilitated the preoperative mapping and the intraoperative dissection of the perfora­tors [20, 23, 24].
It is also important to nd a tool that can be used intraop­eratively to detect the ap perfusion and the safe ap dimensions. Intravenous uorescein administration is one of the methods used for prediction of aps perfusion [25]. However, the indocyanine green near-infrared uorescence angiography was found to be more accurate than the con­ventional uorescein angiography in evaluating skin perfu­sion [26].
42.4 Flap Design andMarkings
The most promising perforator near to the defect should be marked preoperatively using hand-held Doppler or any of the aforementioned modalities (Fig.42.2). A pedicled perforator ap can be designed as a peninsular or islanded ap. In a peninsular ap, a skin bridge should be left intact during ap harvest in addition to the isolated perforator, and examples of this include the uni-bladed propeller, the transposition, and rotation aps. On the other hand, an islanded ap, such as a twin-bladed propeller, keystone, and V-Y advancement, is only vascularized by the isolated perforator [15].
The most common design in the lower limb is the twin­bladed propeller ap (two blades of unequal sizes). For a proper design of this ap, the perforator should act as the pivot point of the ap. Then, the distance between the perfo­rator and the distal end of the defect is measured and trans­ferred proximally along the axis of the main source vessel. The distance between the perforator and the proximal border
of the ap is equal to this measured distance plus 1cm. The width of the proximal part of the ap, which should ll in the defect, equals to the width of the defect plus 0.5cm. This compensates the expected ap contraction and allows for tensionless wound closure [27]. The short arm of the ap, which is the part between the perforator and the proximal tip of the defect, will be used to help closure of the secondary defect either completely or with a skin graft after complete ap dissection and rotation (Fig.42.3).

guide
1. Incision
The posterior border of the designed ap is incised as an exploratory incision down through the deep fascia (Fig.42.4).
2. Pedicle Dissection The ap elevation is performed subfascially, identify-
ing and preserving all potentially suitable perforators. Once all perforators are allocated, the best one should be selected based on the caliber, pulsatility, proximity to the defect, number and caliber of venae comitantes, orienta­tion, and course (Fig.42.5).

Three perforators were marked in this image; P1, P2, and P3 from distal to proximal. P1 and P2 were septocutaneous perforators passing through the septum between the soleus (S) and the exor digi­torum longus (FDL) and were traced down to the posterior tibial vessels (asterisk), while P3 was a musculocutaneous perforator piercing through the soleus muscle
Fig. 42.7 The most appropriate perforator and its accompanying vein were dissected all around for a suitable length
3. Pedicle Preparation Once the most appropriate perforator is chosen, all
other perforators must be ligated (Fig.42.6). The perfora­tor and its accompanying veins should then be dissected long enough to prevent kinking of the vessels when the ap is repositioned (Fig.42.7). When high degree of rota­tion is required (more than 90–100°), perforator skeleton­ization or exposure of the source vessels will be necessary to minimize torsion (Fig.42.8).
4. Flap Adjustment The ap can then be reevaluated and adjusted based on
the chosen perforator (Fig.42.9). The remaining outline of the ap is incised and dissected until completely islanded. The raised ap can now be transferred to the defect as a twin-bladed propeller, keystone, V-Y advance­ment, or even as a free perforator ap. The following steps should be undertaken to inset the ap as a twin­bladed propeller ap.

5. Flap Transfer and Insetting The ap can be rotated up to 180° to reach the recipi-
ent site. The long blade of the propeller ap lls the defect, while the short blade is used to help closure of part of the donor site (Figs.42.10, 42.11, and 42.12). This can be done using skin staples or 3–0 half-buried prolene

sutures. Penrose or rubber drain can be used, but should be placed and secured well away from the perforator (Fig.42.13).

6. Donor Site Closure
After complete inset of the ap in its new position, the donor site can be closed primarily if the ap area is small which enables tensionless closure and gives the best aes­thetic result. In the case of a large donor site defect, a split­thickness skin graft can be used (Fig.42.13).
42.6 Core Surgical Techniques inFlap
Dissection (Propeller Flaps)
The use of a thigh tourniquet without exsanguination is advised to allow engorgement of the venae comitantes and optimize visualization of the perforators. An incision is rst made along the posterior border of the planned ap down through the deep fascia using a blade (size 15 or 10), and then followed by subfascial dissection under loupe magni­cation by the means of sharp, blunt as well as bipolar dissec­tion. Placing anchoring sutures at the ap edges helps to prevent the deep fascia from being separated from the skin and the subcutaneous fat with shearing forces during dissec­tion and gives a better retraction and exposure.
At this stage, the ap dissection technique depends on the type of the ap harvested:
(a) Posterior tibial artery perforator ap:
Subfascial dissection is carried on over the exor digitorum longus muscle, and the perforators can be identied and preserved on the undersurface of the fas­cia between the exor digitorum longus and soleus mus­cles. PTA should be located and mobilized in the distal part of the initial incision to make dissection much eas­ier, and then retracted towards the soleus muscle to make the intermuscular septum more dened. The identied perforators can then be followed down the septum until their origin from the PTA.
A. M. Yassin et al.
(b) Peroneal artery perforator ap:
Subfascial dissection is performed laterally until the musculocutaneous or septocutaneous perforators are identied, and then traced retrograde to the peroneal vessels. If the perforators are found piercing the soleus, peroneus longus or exor hallucis longus muscles, they should be traced intramuscularly with ligation of any encountered muscular branches.
Multiple useful perforators are usually identied and the most appropriate one is selected based on its size, location, number of venae comitantes, subcutaneous course, and ori­entation. This chosen perforator might not be the one identi­ed preoperatively using the hand-held Doppler or the CTA. If in doubt, an Acland clamp can be used to select between two similar-sized perforators.
Once this decision is made, the ap design is rechecked and modied accordingly to make sure that the proximal edge of the ap can be transferred to the distal edge of the defect without tension. The pedicle is then prepared by divi­sion of all fascial strands and muscular side branches associ­ated with the perforator, especially those around the venae comitantes, for at least 2cm to help the ap to rotate up to 180° without signicant spiral twist of the pedicle. A long pedicle will result in a gentler twist, and therefore, less blood ow obstruction in this high degree of ap rotation.
Once the pedicle is prepared, the incision around the ap is completed and the rest of the ap is harvested. When the ap is totally islanded, it usually becomes hyperemic. The tourniquet is then released and the ap should not be rotated into the defect immediately after being completely islanded, but left in its original position for 10–15min. This helps to relieve any vascular spasm involving the perforator, which usually happens following meticulous pedicle dissection, and the ap to reperfuse.
After conrming good perfusion of the ap, it can be rotated into the defect. At this stage, the ap is lifted from its position without applying too much tension on the pedicle, and then pivoted around the perforator. The ap can be rotated to t into the defect in a clockwise or anticlockwise direction. This mainly depends on the angle between the lon­gitudinal axis of the ap and the defect, and the perfect direc­tion of rotation is one that causes the least tension and torsion of the pedicle.
The maximal angle of ap rotation is 180°, and it should not be rotated more than this angle as it can simply be rotated in the opposite direction. If the ap has to be rotated 180° to cover the defect, it should be rotated rst in a clockwise direction. Then the degree of pedicle torsion is noted, any extra fascial strands causing compression on the venae comi­tantes are divided, and the ap perfusion is monitored. The same procedure should be repeated with the ap rotated in the anti-clockwise direction. The direction of rotation is then decided based on the angle which causes the least torsion to

the perforator and maintains best ap perfusion. The results of a study done by Song etal. [28] emphasized the impor­tance of this step and how the direction of ap rotation when a 180° of rotation is required can signicantly affect the overall outcome of propeller aps. They hypothesized that each perforator, and therefore each ap, might have a pre­ferred direction of rotation over another. They also found out that the perforator ow can signicantly be affected by the rotation direction, and the use of the preferred perforator direction may subsequently reduce the rate of the ap loss.
The rst two skin sutures should be placed on the proximal and distal ends of the ap to guard against any further traction on the pedicle, then the rest of the ap is sutured in its new position. The donor site should not be closed under excess tension, as this will cause compression on the main vessel, affecting the blood supply of the ap, and causing edema of the distal leg. If complete primary closure of the donor site cannot be achieved, the remaining defect can be skin grafted.

A 55-year-old hypertensive and diabetic male who works as a butcher presented with an exposed Achilles tendon of his right leg with supercial tendon necrosis. He sustained knife lacera­tion to the back of his right lower leg 8weeks before, followed by wound infection and skin necrosis which was surgically debrided, leaving the distal part of the Achilles tendon exposed. Supercial debridement of the necrotic part of the tendon was performed by the orthopedic team. Debridement of the wound edges was performed, resulting in a 11 × 6 cm defect. The defect was reconstructed using a posterior tibial artery perfo­rator propeller ap. The ap was raised on a distal perforator closest to the defect, rotated about 160° and lled into the defect. Donor site was closed partially with the short blade of the ap and the remaining part was covered with a split-thick­ness skin graft. The ap survived completely and the patient had an uneventful postoperative recovery (Figs.42.14, 42.15,
42.16, 42.17, 42.18, 42.19, and 42.20).

42.8 Pearls andPitfalls
Pearls
• The initial incision over the ap should be designed with the possibility of becoming an edge for an alternative ap in case a suitable perforator is not detected intraoperatively.
• Avoid perforators that are too far from the defect, as they can cause the ap to be unnecessarily long.
• On the medial side of the leg, care should be taken not to include the long saphenous vein in the ap to avoid the vein becoming engorged with blood with nowhere to drain. Saphenous nerve should also be preserved to avoid postoperative distal numbness. On the lateral side of the leg, try to exclude the sural nerve to avoid loss of sensation of the lateral aspect of the distal leg and foot.
• When a perforator is chosen, it is best to make sure that the lateral dimensions of either sides of the pedicle are equidistant before cutting the other edge of the ap in order to avoid any excessive sideway traction on the pedicle after ap inset.
• If there is a reasonable cutaneous vein at the proxi­mal border of the ap, it is recommended to dissect it for about 1–2cm before ligating so it can be used as a lifeboat in case of ap congestion. In 2019, Kosutic [29] discussed the concept of hybrid perfo­rator aps. In this study, 25 perforator aps were included, and in all of them, 1–2 supercial veins were dissected on the ap edge and used for pro­phylactic supercharging. After ap rotation, this prepared supercial ap vein was anastomosed microscopically with another vein on the edge of the defect. This additional step could enable the sur­geon to harvest a larger ap more safely, use the entire raised ap more reliably, reduce the compli­cations rate and improve the overall outcome of propeller aps.
• Topical vasodilators as papaverine or verapamil can be applied around the perforator after completion of dissection and before ap rotation.

Pitfalls
• Perforators in an area of scar, granulation tissue, or zone of injury are more fragile and can be easily injured. According to the latest British Orthopaedic Association and British Association of Plastic, Reconstructive and Aesthetic Surgeons (BOA/ BAPRAS) 2020 guidelines for the management of open fractures, the use of local perforator aps should be limited to relatively low-energy injuries with a small-sized zone of injury. Free tissue trans­fer is recommended in cases of higher energy type of traumas and those associated with degloving injuries [30].
• A pedicle that is skeletonized more than required increases the risk of occlusive twist and hence affects the ap perfusion.
• Raising a propeller ap on two adjacent perforators can compromise its blood supply after inset, as they can be twisted around each other with ap rotation.
• Bulky dressing should be avoided as it can cause compression on the ap and vascular embarrass­ment. Bandaging should be soft and light, and a window should be made in the dressing to observe the ap.
• Venous congestion is the most common complica­tion and the primary cause of ap necrosis. Flap salvage in that case should be commenced as soon as possible by removing some distal stitches to release excess tension, local heparinization of the ap or applying leeches. Negative pressure wound therapy will be valuable in such cases especially those that end with partial supercial ap necrosis.

This paper provides a historical review, the anatomical
basis, the preoperative investigations and design of the
417
common perforator-based aps for reconstruction of leg and foot defects. It also focuses on the surgical tech­nique and the postoperative follow-up of this kind of aps.

This cadaveric study provides a comprehensive anatomi-
cal illustration of the perforators arising from the main arteries of the leg (the anterior tibial, the posterior tibial, and the peroneal arteries), and how this can be applied clinically in the design of pedicled perforator aps for reconstruction of the lower leg defects.
• Georgescu AV. Propeller perforator aps in distal lower leg: evolution and clinical applications. Arch Plast Surg. 2012;39(2):94–105.
The author highlighted some of the tips for the design and
harvesting technique of propeller perforator aps in the lower leg. He also addressed the most common complica­tions that could happen postoperatively and the best way to deal with them.

This article provided a good illustration for the preopera-
tive investigation and planning for a propeller ap. Then the authors went through their standard step-by-step approach for the ap harvesting technique and a number of harvesting variations. They also discussed their post­operative ap monitoring protocol and their recommen­dations for the ap salvage in case of postoperative venous congestion.
