  • The anterolateral thigh free flap was first reported by Song et al. in 1984 as a fasciocutaneous flap based on septocutaneous or musculocutaneous perforators of the lateral femoral circumflex vessel. It only becomes popular recently through confirmation of additional anatomy. For reconstruction of Achilles area defect, a thin flap is required to improve aesthetic and functional results. The anterolateral thigh free flap is relatively thin and can provide large skin area. It can be a useful option for reconstruction of Achilles area defect based on these characters. Since March 2002, we have successfully transferred 4 anterolateral thigh free flaps to reconstruct Achilles area defects and have attained good range of motion in this region. The anterolateral thigh free flap has many advantages and can be used for the reconstruction of Achilles tendon area defect.

  • With the advent of microsurgery, perforator free flap is nowadays considered the first choice for reconstruction of the extensive defect of the extremities because of their moderate thickness. Among them, anterior (anterolateral and anteromedial) thigh perforator free flaps provide the first choice for reconstruction of various soft tissue defects of the extremities with many advantage such as its large, uniform thickness, long vascular pedicle with proper vessel size and minimal donor site morbidity. But, it has still some criticism of unreliable perforators which makes us very careful in elevating the flap. Between March of 2006 and February of 2007, we treated 7 patients of soft tissue defects in the hand and lower extremities with anterior thigh perforator free flap at Hallym and DongGuk University Hospital. We performed 6 anterolateral thigh perforator free flaps based on the descending branch of lateral circumflex femoral artery (LCFA) and 1 anteromedial thigh perforator free flap based on the innominate branch of the LCFA. While approaching for the anterolateral thigh free flap, we happen to meet the cases which we should change into the anteromedial thigh free flap uneventfully on the operating field. In contrast to the original design of anterolateral thigh free flap, we had to harvest the anteromedial thigh perforator free flap in 1 case. All the anterior thigh perforator free flaps survived completely except 1 case of partial necrosis due to venous congestion. Donor sites were closed primarily and healed uneventfully within 2 weeks. Patients were satisfied with the functionally and aesthetically acceptable results. Although doppler sonography is strongly recommended preoperatively in planning the anterior thigh perforator free flaps, we should always remember the variation in vascular anatomy and be ready to change the flap choice from the anterolateral to anteromedial intraoperatively. we provide a review of the literature and present our series of anterior thigh perforator free flaps for reconstruction of the extremities.

  • Since R.Y. Song(1982) has reported anatomic studies about septocutaneous perforator flap, various experiences especially on thigh flaps pedicled on septocutaneous artery were reported. Baek(1983) reported an anatomic study through the cadavers dissections on medial, lateral thigh area and provided the first new cutaneous free flap of thigh for clinical use. Song, et a1.(1984) reported anterolateral thigh free flap, Koshima, et al.(1989) reported pedicle variations and its versatile clinical usages. According to their reports, accessory branches of lateral femoral circumflex artery are placed in comparatively constant location and proved to be the effective pedicle of this flap. The advantages of anterolateral thigh free flap are 1) comparatively thin 2) can obtain sufficiently large flap 3) can contain cutaneous nerve 4) can be easy to approach anatomically because pedicle is located in comparatively constant position 5) minimal donor site morbidity. We report the experience of 10 cases of anterolateral thigh free flap coverage for soft tissue defects: 4 cases of soft tissue defects on foot area, 2 cases of soft tissue defects on hand, 3 cases of partial tongue defects owing to tongue cancer ablation, and 1 case of soft tissue defect on nasal alar.

  • Purpose: The objective of this study is to present a reliable method of scrotal reconstruction. Methods: 75 year - old - man visited the out patient department of urology for chronic itching sensation in his scrotal area, diagnosed as Bowen's disease. After the wide resection of scrotal lesion, reconstruction was carried with pedicled anterolateral thigh perforator flap. All operation procedure was done with an usual manner, previously reported. Donor site was closed primarily. Results: In 6th month follow - up period, there was no event, such as flap necrosis, wound dehiscence, tumor recurrence. And tactile sensation was recovered. Conclusion: In the Korean literature, there have not been the report that describes the reconstruction of scrotal defect using pedicled anterolateral thigh perforator flap. Pedicled anterolateral thigh perforator flap is reliable and robust flap for scrotal reconstruction.

  • The anterolateral thigh flap(ALT flap) was originally described in 1984 as a septocutaneous nap based on the descending branch of the lateral circumflex artery. This nap has some significant advantages for reconstruction of the head and neck. It can be raised as a subcutaneous flap, a fasciocutaneous nap, or a myocutaneous nap and can resurface large defects in the head and neck. In addition, it has a large and long vascular pedicle, and because of the distance of the donor site from the head and neck, it can easily be harvested with a two-team approach. However, the number and locations of cutaneous perforators vary individually, and thus, it is not widely used because nap elevation is often complicated and time-consuming owing to unexpected anatomical variations. The purposes of this study are to clarify the vascular anatomy and to assess the suitability of anterolateral thigh nap for oral cavity reconstruction in Koreans. In addition, we used anterolateral thigh free nap for oral cavity reconstruction in 20 oral cancer patients from 2006 to 2011. Through our clinical experience, we discuss a series of practical "pearls and pitfalls". Our experience has not only given us new flap choice using anterolateral thigh nap in oral cavity reconstruction, but also given us a new possibility on the applicability of chimeric naps.

  • Tongue reconstruction after oncologic resection with free flap is important to conserve function and shape. Vertical rectus myocutaneous free flap is usually used for total tongue reconstruction, but our patient was thin and primary closure after flap elevation seemed hard. So we used anterolateral thigh free flap to reduce donor site morbidity and to maintain bulk of the tongue as much as possible. Deepithelization of both middle side of flap and folding was done to mimic normal tongue base's shape and volume. Flap survived without complication and patient underwent concurrent chemoradiation therapy three weeks after surgery. Anterolateral thigh free flap can be good candidate for total tongue reconstruction especially in thin patient.

  • Purpose: The anterolateral thigh flap has many advantages over other conventional free flaps. But the anterolateral thigh flap has yet to enter widespread use because perforating arteries exhibit a wide range of anatomic variations and are difficult to dissect when small. The aim of this study is to identify the vascular variability of perforating arteries and pedicle in the anterolateral thigh free flap. Methods: We studied 12 cadavers and dissected 23 thighs. An anterolateral thigh flap ($12{\times}12cm$) was designed and centered at the midpoint of the line drawn from anterior superior iliac spine to the superolateral border of the patella. After we identifed the perforating arteries we dissected up to their origin from lateral circumflex femoral artery along descending branch of lateral circumflex femoral artery. We then investigated the number and the position of perforating arteries, length and diameter of vascular pedicle and pattern of lateral circumflex femoral arterial system. Results: On average $2.3{\pm}1.1$ perforating arteries per thigh were identified. The musculocutaneous perforators were 63.1%. In those perforators five perforators were arose from transverse branch of lateral circumflex femoral artery and two were arose from rectus femoral artery. Most of the perforators were near the intermuscular septum between rectus femoris muscle and vastus lateralis muscle. The length and diameter of pedicle were $11.9{\pm}3.5cm$ and $3.1{\pm}0.8mm$ on average. Conclusion: This study will be helpful for the success in anterolateral thigh free flap.

  • Purpose: The anterolateral thigh flap is versatile flap for soft-tissue reconstruction for defects located at various sites of the body. This useful flap offers a thick and vascular fascia lata component with large amounts that can be soft tissue coverage for different reconstructive purposes. We present our clinical experience with the use of vascular fascia lata, combined with anterolateral thigh flap for various reconstructive goals. Methods: From April 2008 to February 2011, we transferred anterolateral thigh flaps with fascia lata component to reconstruct soft-tissue defects for different purposes in 11 patients. The fascia lata component of the flap was used for tendon gliding surface in hand/forearm reconstruction in 4 patients, for reconstruction medial and lateral patellar synovial membrane and retinaculum in 2 patients, for reconstruction of plantar aponeurosis in the foot in 2 patients, for reconstruction of fascial and peritoneal defect in the abdominal wall in 2 patient, and for dural defect reconstruction in the scalp in the remaining one. Results: Complete loss of the flap was not seen in all cases. Partial flap necrosis occurred in 2 patients. These complications were treated successfully with minimal surgical debridement and dressing. Infection occurred in 1 patient. In this case, intravenous antibiotics treatment was effective. Conclusion: Anterolateral thigh flap has thick vascular fascia with large amounts. This fascial component of the flap is useful for different reconstructive aims, such as for tendon, ligament, aponeurosis defects, abdominal wall or dura reconstruction. It should be considerated as an important advantage of the flap, together with other well-known advantages.

  • Purpose: As the soft tissue defect around the knee is difficult to reconstruct, local flap or free flap is used. Distally based anterolateral thigh pedicled flap introduced by Zhang uses sufficient reverse flow supplied from the vascular network around the knee. We report successful reconstruction of defect around knee by this method. Methods: Four patients with skin & soft tissue defect around knee have been treated for reconstruction using the distally based anterolateral thigh pedicled flap. First, the doppler was used to check the perforator flap of the descending branch of the lateral circumflex femoral artery and to draw and dissect the perforator flap as much as needed. After the dissection, the proximal of the descending branch was clamped and checked for sufficient supply of blood flow from the reverse flow and then ligated. It was dissected along the descending branch and in order to prevent damage to the joined parts of the descending branch and the lateral superior geniculate artery, a more careful ligation was done starting from 10 cm superior to the knee. The defect was reconstructed after securing enough vascular pedicle to cover all the damaged parts. Results: Not all patients suffered from flap necrosis. In case of the patient with chronic osteomyelitis, slight venous congestion was observed right after the surgery but it disappeared the following day. All three patients had no occurences of additional complications. Conclusion: Distally based anterolateral thigh pedicled flap was enough to provide large flap for knee reconstruction. It had sufficient blood flow and vascular pedicle. It also had taken short operation time compared to the free flap operation. The distally based anterolateral thigh pedicled flap used by the authors is a very useful way of reconstructing the area around knee.
