Methods: From May 2013 to October 2015, 20 cases of patients received femoral anterolateral free flap transplantation, with the flap transported to the recipient site. After reascularization, the phase I of thin flap repairing was performed in each 'vein type'area. Among those, there existed 8 cases of direct suture in the donor site, and 12 cases of skin transplantation by intermediate split thickness skin graft. Results: All the postoperative flaps survived, with 2 cases of vascular crisis and 2 cases of poor venous return at the edge of flap. No complications such as flap infection and necrosis occurred. Wounds and incisions in donor and recipient sites were healed in phase I. 20 cases of patients had been followed up for 5-24 months, and the average follow-up time was 15 months. The skin texture of flap was similar to the surrounding skin, with good abrasion resistance, no ulceration and no phase II flap repairing;the sensation of flap recovered to S3-S4 level;the two-point discrimination was 3.5-6.0 mm, with the average value of 5.0 mm. The function of patients' fingers recovered well without any complications such as contracture and deformity etc. In the last follow-up, Testative Evaluation Standard of Upper Limb Function, which was established by Chinese Medical Society for Surgery of Hand, was used to assess efficacy, and the evaluation results were as follows: excellent in 9 cases, good in 5 cases, fair in 6 cases;in accordance with the evaluation criteria listed in Michigan Hand Outcome Questionnaire (used to assess patients' satisfaction with the appearance of flaps after operation, and the results were as follows: very satisfactory in 9 cases, satisfactory in 9 cases, and moderate in 2 cases. Conclusions: After reascularization in femoral anterolateral free flap grafting, phase I of thin repairing has small effects on flap vascularization, with a satisfactory appearance of the flap.展开更多

Methods： Anterolateral thigh flap with the descending branch of the lateral circumflex femoral artery and the pedicle of anterolaterat thigh cutaneous nerve was used in primary repairing of the defect from postoperative vulva tumor, the sizes of the flaps ranged from 10 cm ×14 cm-14 cm× 20 cm. Results： All flaps survived, during a follow-up of 2 to 12 months, the appearance of the flaps was satisfactory with sensitive function without local recurrences. Conclusion： Anterelateral thigh flap has fairly long vessel pedicle, wider vessel diameter, and is in the covert area. Anterolateral thigh flap with sensory nerve is the ideal choice for postoperative repairing of vulva tumor.展开更多

COVID-19, as a pro-thrombotic disorder, therefore seems detrimental to free flap survival. We encountered a case of unique pattern of free flap partial failure in a young male who underwent extremity reconstruction. The patient was diagnosed as COVID-19 positive on the 3rd day post-reconstruction. The flap survived well for the first 7 days post-operatively, but gradually the skin got necrosed and the subcutaneous fat layer was preserved when debriding. To our knowledge, this is the only case in which the skin of the free flap of a COVID-19 positive patient was necrosed almost entirely subsequently, while the subcutaneous fat was relatively preserved.展开更多

This impairment renders individuals more susceptible to excessive bleeding during significant surgical interventions. Moreover, individuals with severe hemophilia frequently encounter recurring hemarthrosis, resulting in progressive joint destruction and, subsequently, the need for hip and knee replacement surgeries.CASE SUMMARY The patient was a 53-year-old man with hemophilia A as the underlying disease and had self-injected factor Ⅷ twice weekly for several decades. He had undergone ankle fusion surgery for recurrent hemarthrosis at the Department of Orthopedic Surgery 1 mo prior and was referred to our department because of skin necrosis after a hematoma at the surgical site. An anterolateral thigh perforator free flap was created after three cycles of factor Ⅷ administration in addition to the concomitant administration of tranexamic acid(TXA)(Transamin 250 mg cap, 1 cap tid, q8h). After the operation, from postoperative days(PODs) 1-5, the factor Ⅷ dose and interval were maintained, and q12h administration was tapered to q24h administration after POD 6. Because the patient’s flap was stable 12 d after the operation, factor Ⅷ administration was tapered to twice a week. At 6 mo follow-up, the patient recovered well without any complications.CONCLUSION To the best of our knowledge, there are very few reports of successful free flaps in patients with hemophilia, and none have been reported in patients with hemophilia A. Moreover, there are several reports on the efficacy of TXA in free flaps in general patients;however, there are no case reports of combining factor Ⅷ and TXA in patients with hemophilia. Therefore, we report this case to contribute to future academic research.展开更多

文摘BACKGROUND Reconstructive repair of huge full-thickness abdominal wall defects following debridement for abdominal electric burns remains a clinically challenging task.An ideal abdominal wall repair means a re-closure of the defected abdominal wall with pedicled neurovascular myofascial flaps,restoration of the abdominal wall integrity,and maintenance of the abdominal wall muscle tension to prevent the occurrence of abdominal wall hernia.When treating huge full-thickness defects,composite autologous tissue flaps are a good option for the repair.CASE SUMMARY This study reported the case of a 43-year-old male patient suffering from fullthickness abdominal wall defects complicated with necrosis of multiple bowel segments and duodenal leak following high-voltage burns involving the left upper limb and abdomen.After debridement for abdominal electric burns and end-to-end anastomosis for the necrotic bowels,reconstruction with acellular dermal matrix grafting and vacuum sealing drainage were performed for temporary abdominal closure.The remaining 18 cm×15 cm full-thickness abdominal wall defect was repaired using a combined anterolateral thigh and tensor fascia lata free flap.The proposed method achieved the functional reconstruction of the abdominal wall.CONCLUSION This approach restored the abdominal wall integrity,maintained certain muscle tension,avoided abdominal hernia,reached satisfactory aesthetic effect,and resulted in no complications in the grafting regions.
