Reliability and Safety of Cross-Leg Free Latissmus Dorsi Muscle Flap in Reconstruction of Mutilating Leg Injuries Using End-to-Side Anastomosis. Arch Plast Surg 2023; 50:507-513. [PMID: 37808335 PMCID: PMC10556300 DOI: 10.1055/a-2126-7058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Accepted: 07/04/2023] [Indexed: 10/10/2023] Open
Abstract
Background Free tissue transfer is considered the gold standard option for the reconstruction of distal leg defects. Free tissue transfer using recipient vessels in the contralateral leg (cross-leg bridge) is a potential option to supply the flap if there are no suitable recipient vessels in the injured leg. Most studies have described this technique using end-to-end anastomosis which sacrifices the main vessel in the uninjured leg. This study evaluated the use of a cross-leg free latissimus dorsi muscle flap for the reconstruction of defects in single-vessel legs, using end-to-side anastomosis to recipient vessels in the contralateral leg without sacrificing any vessel in the uninjured leg. Methods This is a retrospective study that included 22 consecutive patients with soft tissue defects over the lower leg. All the reconstructed legs had a single artery as documented by CT angiography. All patients underwent cross-leg free latissimus dorsi muscle flap using end-to-side anastomosis to the posterior tibial vessels of the contralateral leg. Results The age at surgery ranged from 12 to 31 years and the mean defect size was 86 cm 2 . Complete flap survival occurred in 20 cases (91%). One patient had total flap ischemia. Another patient had distal flap ischemia. Conclusion Cross-leg free latissimus dorsi muscle flap is a reliable and safe technique for the reconstruction and salvage of mutilating leg injuries, especially in cases of leg injuries with a single artery. As far as preservation of the donor limb circulation is concerned, end-to-side anastomosis is a reasonable option as it maintains the continuity of the donor leg vessels.

Abstract
BACKGROUND Complex lower limb reconstruction due to severe trauma remains a challenge for reconstructive surgeons. Here, we introduce a modified donor blood flow-preserved cross-leg anterolateral thigh flap procedure and evaluate its clinical efficacy. METHODS Between January 2013 and December 2019, 22 patients (range 10 to 64 years old) with unilateral lower limb injury underwent modified donor blood flow-preserved cross-leg anterolateral thigh flap procedures. Among them, 16 cases were traffic accidents, 5 cases were persistent ulcers, and 1 case was a degloving injury. The arterial pedicle of the flap was prepared in a Y-shaped fashion and microanastomosed to the posterior tibial artery of intact leg in a flow-through style. A split-thickness skin graft was applied to wrap the vascular pedicle after anastomosis. The flap was designed in a single or bilobed fashion according to the shape of the tissue defect. The operation time, the intraoperative blood loss and the length of hospital stays were recorded. The vascular pedicle was divided 4 weeks after anastomosis. Doppler ultrasound was performed to evaluate the blood flow of the donor posterior tibial artery during postoperative follow-up. RESULTS All 22 flaps survived. The tissue defects ranged from 12 × 6 to 21 × 18 cm2. The flap sizes ranged from 14 × 7.5 to 24 × 21 cm2. The average operation time, intraoperative blood loss and length of hospital stays were 6.73 ± 1.49 h, 280.95 ± 59.25 ml and 30.55 ± 2.52 days, respectively. Eighteen flaps were designed in a single fashion, while four were in bilobed fashion. Twenty patients underwent fasciocutaneous flap transplantations, while two underwent musculocutaneous flap transplantations. Two cases developed local lysis of the flap which healed after further debridement. Direct suture of the incision after flap harvest was performed in 16 cases, while additional full-thickness skin grafting was performed in the remaining 6 cases. Further bone transport procedures were performed in 15 patients who had severe tibia bone defects. The blood flow of donor posterior tibial artery was confirmed in all patients during follow-ups. All patients recovered flap sensation at the final follow-up. The postoperative follow-ups ranged from 18 to 84 months, and no long-term complications were observed. CONCLUSIONS The modified donor blood flow-preserved cross-leg anterolateral thigh flap procedure is an ideal method to repair severe lower limb trauma with tibial artery occlusion which avoids sacrificing the major artery of the uninjured lower limb.

Abstract
When there is no suitable vessel in the injured leg for microsurgical transfer, cross-leg free flaps can be considered for lower extremity reconstruction. This report describes patients who experienced lower extremity trauma and underwent reconstruction with cross-leg free flaps with preserved blood flow in the recipient artery. Anterolateral thigh flap is preferred for small to moderate defects. The descending branch of the lateral femoral circumflex artery was dissected 2 cm proximally and distally and was prepared in a T-shape. The branches of the T were anastomosed to the recipient artery in the contralateral leg in the first session of the cross-leg free flap procedure. After 3 weeks, the flap artery was separated from the bifurcation. For large defects, the latissimus dorsi flap was chosen. The thoracodorsal artery was anastomosed to the contralateral posterior tibial artery in the first session. After 3 weeks, to provide recipient vessel integrity, the thoracodorsal artery was transected from the flap and anastomosed to the distal stump of the posterior tibial artery. Between January 2017 and January 2019, 8 defects were reconstructed using an anterolateral thigh flap; the remaining 4 defects were reconstructed using a latissimus dorsi flap. All flaps survived without complications. Anterograde flow distal to the anastomosis was confirmed in all recipient arteries via Doppler ultrasound. In cross-leg free flaps, the continuity of the recipient artery can be established to prevent diminished blood flow to the recipient extremity.

Abstract
BACKGROUND The management of a high voltage electrical injury and lower limb salvage remains a challenging task for plastic surgeons. Reconstruction with flaps is often the only alternative to limb amputation. The purpose of this study was to present a cross flow-through pedicle free latissimus dorsi muscle flap for the salvage of severely traumatized lower limbs perfused by one remaining vessel (a single vessel lower limb) in high voltage electrical injuries. METHODS In this retrospective study, between 2000 and 2014, six men underwent cross-leg free Latissimus dorsi muscle flap operations for limb salvage. They had soft tissue lower leg defects due to high voltage electrical injuries. Their medical records were retrospectively reviewed. All had only one artery that perfused the leg. Free pedicled thoracodorsal artery latissimus dorsi flaps were harvested and connected to the contralateral posterior tibial artery. RESULTS All defects were successfully covered. No flap loss or major amputation occurred during follow-up (mean; 5.9 years). A computerized tomography angiogram showed intact vessel continuity in the recipient vascular system. The patients were able to walk without any apparatus or assistance after long term follow-up. CONCLUSION We recommend that the cross flow-through pedicle free muscle flap should be considered as a salvage procedure for single vessel lower extremities resulting from high voltage electrical burns. Extremity perfusion was not compromised by this procedure.

Abstract
We describe a simple and reliable technique for tunneling of the vascular pedicle of the free flap with a long pedicle, that may otherwise cause twisting and/or kinking of the pedicle. There are two modifications of the technique. In the cross-groin anastomosis modification, using a haemostat in a blunt manner, a suprapubic subcutaneous tunnel is created between two groin regions. The vascular pedicle of the flap is pulled and passed through this tunnel to the contralateral region. While the anastomoses are done on one site, the flap is inserted to the contralateral groin. In the second modification ('groin anastomosis-cross dorsum flap insert procedure'), the flap is transferred to the dorsum of the rat at approximately the same level of the groin. Using a haemostat, a large subcutaneous tunnel safe enough for the pedicle is created between the groin region and the rat dorsum lateral to the hip region. The anastomoses are done in the groin region, and the flap is inserted on the dorsum. This technique was used in 16 animals, with a free cutaneous maximus muscle musculocutaneous flap transfer based on the axillary vessels being done in eight animals; and a posterior thigh perforator-based flap based on the popliteal vascular pedicle in the remaining eight. Both groups had a pedicle length of approximately 4 cm, with a 100% survival rate. In conclusion, the technique is simple, reliable, and can be easily carried out without necessitating special procedures. It provides a straight course for the vascular pedicle with tension-free anastomosis by appropraitely adjusting the distance of the vascular anastomosis and flap insertion site.

Abstract
The purpose of this report is to introduce the cross-leg anterolateral thigh perforator flap for closure of a defect on the dorsum of the foot, and to show that the anterolateral thigh perforator flap is a safe option for a cross-bridge microvascular anastomosis in defects of the extremity. The free anterolateral thigh perforator flap was used for a patient with an unhealed wound on the dorsum of the foot. The flap was revascularized by end-to-side anastomosis between the flap's artery and the posterior tibial artery of the other leg, since there was no available recipient artery on the same leg. After a 4-week neovascularization period, the pedicle was cut. To the best of our knowledge, this is the first report of the use of a free anterolateral thigh perforator flap for a cross-bridge microvascular anastomosis.
