  • Propeller facial artery perforator flap for repairing defect after resection of skin malignant tumor at upper lip

    ObjectiveTo explore the effectiveness of propeller facial artery perforator flap to repair the defect after resection of skin malignant tumor at upper lip.MethodsBetween July 2012 and January 2017, 17 cases with skin malignant tumor at upper lip underwent tumor resection and the remained defect was repaired with propeller facial artery perforator flap. Among the 17 patients, 3 were male and 14 were female, with an average age of 57 years (range, 35-82 years). There were 5 cases of squamous cell carcinoma and 12 cases of basal cell carcinoma. The disease duration ranged from 4 months to 11 years with an average of 20 months. The tumor size ranged from 1.4 cm×0.3 cm to 3.1 cm×1.4 cm. The extended resection of the tumor tissue was performed according to the characters of tumor. According to the location, size, and shape of the defect and the position of facial artery perforator explored with Doppler ultrasonography, the propeller facial artery perforator flap was designed to repair the defect and partial donor site. The flap size ranged from 5 cm×2 cm to 7 cm×3 cm. The length of the perforator pedicle was 0.5–1.0 cm with an average of 0.8 cm. The defect at donor site was directly closed.ResultsCyanosis occurred in 3 cases of the distal flap after operation, then healing after symptomatic treatment. The remaining flaps survived successfully and the wound healed by first intention. Primary healing was obtained in the donor site. All the patients were followed up 6-36 months with an average of 18 months. The shape of the patient’s upper lip was good and the scar on the donor site was unconspicuous. There was no lip deformity, ala nasi deflection, facial tension, entilation dysfunction, or recurrence of tumor during follow-up. At last follow-up, the results of self-evaluation were very satisfactory in 13 cases and satisfactory in 4 cases.ConclusionBased on multiple advantages of good blood supply, large rotation range, aesthetic outcome, and slight injury of the donor site, propeller facial artery perforator flap is not only an optimal choice for repairing upper lip defect after resection of skin malignant tumors, but also can achieve good functional and cosmetic effectiveness.

    ObjectiveTo explore the feasibility of using indocyanine green (ICG) angiography to detect brachial artery perforators, and the clinical application of brachial artery perforator propeller (BAPP) flaps to repair soft tissue defects of the trunk and upper limbs.MethodsBetween August 2016 and February 2019, ICG angiography was used to detect the perforating vessels of the brachial artery muscle septum, and the BAPP flaps were cut out with the detected perforating vessels as the pedicle to repair 19 cases of trunk and upper limb soft tissue defects. There were 12 males and 7 females, with an average age of 28.6 years (range, 5-66 years). Etiologies included the post-burn scar in 10 cases, soft-tissue sarcoma in 5 cases, congenital melanocytic nevi in 2 cases, chronic chest wall ulcer in 1 case, and malignant melanoma in 1 case. Defects located in axilla in 8 cases, chest wall in 4 cases, elbow in 5 cases, and shoulder in 2 cases. The area of the defect ranged from 15 cm×3 cm to 20 cm×8 cm. Pre-transfer tissue expansion was used in 11 patients. Thirteen flaps were pedicled with 1 perforator vessel, and 6 flaps were pedicled with 2 perforator vessels. The length of the vascular pedicle was 2.5-4.5 cm, with an average of 3.08 cm. The area of the skin flap ranged from 11 cm×5 cm to 22 cm×10 cm. The flap rotation angle was 110° in 1 case, 120° in 1 case, and 180° in 17 cases. Except for one donor site repaired by skin graft, the other donor sites were directly sutured.ResultsA total of 24 perforating vessels of the brachial artery muscle septum were detected by ICG angiography, 26 were identified during the operation, with an accuracy rate of 92.31%. Eighteen flaps survived without arteriovenous crisis. Venous congestion was observed in the distal 3-cm of one flap and the flap survived after conservative management. Intraoperative analysis showed that the blood perfusion of the distal 4-cm of one flap was poor, the relative value was less than 32%, the flap survived after removing the poor perfusion area. All the patients were followed up 3 to 23 months (mean, 8.6 months). The color and texture of the flap were similar to those of the recipient area. Flap debulking was not needed in all patients owing to the thinness of the flap. The contracture symptoms of patients with scar contracture on the medial of the elbow joint and axilla were significantly improved; a patient with malignant melanoma underwent tumor resection at 1 year and 5 months after operation due to tumor recurrence, and additional surgery was done to remove the recurrent tumor. No tumor recurrence was found in other patients.ConclusionThe ICG angiography technique can be used to explore the perforating vessels of the brachial artery muscle septum. The BAPP flap pedicled with the perforating vessels can be used for the repair of skin and soft tissue defects in the chest wall, axilla, shoulder, and elbow joint.

Methods Between October 2013 and May 2019, 10 patients underwent repairing of soft-tissue defects around the knee joint using the SLGA perforator propeller flap. There were 6 males and 4 males, with a median age of 34.5 years (range, 6-66 years). Etiologies included radical tumor resection in 4 cases, post-burn scar contracture in 3 cases, post-burn hypertrophic scar in 2 cases, and prothesis exposure after knee arthroplasty in 1 case. Defects located on the lateral knee in 6 cases, proximal lateral leg in 2 cases, popliteal fossa in 1 cases, and infrapatellar region in 1 case. The size of soft-tissue defects was from 6 cm×4 cm to 14 cm×8 cm. The extraction range of the flap was from 10.0 cm×5.5 cm to 23.0 cm×7.0 cm; the length of the perforator pedicle was 2.5-5.0 cm, with an average of 3.65 cm; the flaps were rotated 180°, the large paddle of the propeller flap was used to repair the defect, and the small paddle was used to assist the closure of donor site. Results Blister was observed in the distal 3-cm of one flap and the flap survived after conservative management. All the flaps survived, and the wounds in the donor and recipient areas healed by first intention. There was no vascular crisis, incision dehiscence, infection, or other complications. All 10 patients were followed up 4 to 48 months, with an average of 12.6 months. The color and texture of the flap were similar to those of the recipient area, and there was no need for secondary operation for degreasing and thinning. Scar contracture was corrected; no tumor recurrence was found in tumor patients; the artificial knee joint was preserved, the knee joint flexion and extension activities were good, and all the patient and family members were satisfied with the appearance and function of the lower limbs after operation.

    Objective To explore the feasibility and effectiveness of perforator propeller flap sequential transfer technique in repair of soft tissue defect of distal lower extremity. Methods Between July 2015 and July 2021, 10 patients with soft tissue defect of distal lower extremity were treated with perforator propeller flap sequential transfer technique. There were 8 males and 2 females, with a median age of 47 years (range, 6-71 years). The etiologies included malignant tumor in 5 cases, trauma in 3 cases, postburn scar contracture in 1 case, and diabetic foot ulcer in 1 case. The defects were located at the pretibial area in 1 case, the distal lower extremity and Achilles tendon in 3 cases, the dorsum of foot and lateral malleolar area in 4 cases, the heel in 1 case, and the plantar foot in 1 case. The size of the defect ranged from 5 cm×3 cm to 8 cm×8 cm. Peroneal artery perforator propellor flaps (the 1st flap) in size of 14 cm×4 cm to 29 cm×8 cm were used to repair the defects of distal lower extremity. The donor site defects were repaired with the other perforator propeller flaps (the 2nd flap) in size of 7 cm×3 cm to 19 cm×7 cm. The donor site of the 2nd flap was directly closed. ResultsAll the operations were successfully completed and all of the 2nd flaps were elevated within 1 hour. Eight the 1st flaps survived completely; 2 had venous congestion. Among the 2 patients with venous congestion, 1 had necrosis of the distal end of the flap, and the secondary wound was repaired by skin grafting; 1 recovered spontaneously after 7 days. The 2nd flaps totally survived. No complication such as hematoma or infection occurred. Primary closure was achieved in all the recipient and donor sites. All patients were followed up 2-39 months, with a median of 15.5 months. The color, texture, and thickness of the flaps matched well with those of recipient sites. The normal contour of the leg was preserved. During follow-up, no recurrence of malignance or ulcer was observed. The scar contracture was completely released. All patients were satisfied with the reconstructive outcomes. Conclusion The application of the perforator propeller flap sequential transfer technique can improve the repair ability of the lower extremity perforator propeller flap while ensuring the first-stage closure of the donor site, thereby improving the effectiveness.

    Objective To investigate the effectiveness of the perforator-based propeller flaps (PPFs) based on digital artery (DA) and dorsal metacarpal artery (DMA) in repairing hand wounds. Methods The clinical data of 45 patients with hand wounds between January 2018 and March 2023 were retrospectively analyzed. There were 27 males and 18 females with an average age of 41.2 years (range, 14-72 years). The causes of injury included twist injury in 15 cases, crush injury in 19 cases, and cut injury in 11 cases. The injured parts included 32 cases of digits, 10 cases of dorsal hand, and 3 cases of palmar hand, all of which had tendon, joint, and bone exposure. The time from injury to operation ranged from 2 to 8 hours (mean, 4.3 hours). The wound sizes after debridement ranged from 1.8 cm×1.0 cm to 5.0 cm×3.5 cm. Twenty-eight cases were repaired by the PPFs based on DA and 17 cases were repaired by the PPFs based on DMA. The flap size ranged from 2.5 cm×1.1 cm to 8.5 cm×4.0 cm. The defects of the donor sites in 14 patients were closed directly and the defects in the left 31 patients were resurfaced with free full-thickness skin graft from the proximal medial forearm.Results All the flaps survived after operation. Two cases of the PPF based on DA and 1 case of the PPF based on DMA underwent partially blisters at the distal end and healed after dressing change. The incisions in the donor site healed by first intention and the skin grafts survived. All patients were followed up 10-33 months, with a mean of 15.4 months. At last follow-up, the static two-point discrimination of the PPFs based on DA and DMA were 4-14 mm and 8-20 mm with the averages of 8.1 mm and 13.3 mm, respectively. According to the Michigan Hand Outcomes Questionnaire, 20 patients were very satisfied with the appearance of the PPF based on DA and 8 patients were satisfied; 8 patients were very satisfied with the appearance of the PPF based on DMA and 9 patients were satisfied. Based on the Vancouver Scar Scale (VSS), the appearance scores of the donor site of the PPFs based on DA and DMA were 2-7 and 4-9, with the averages of 4.2 and 6.1, respectively. ConclusionThe two kinds of PPFs are reliable in blood supply and easy to harvest, which provide a good method for emergency repair of small and medium area wounds in the hand.
