In this series of 62 free flap transfers, 48 (80%) have been successful. There have been a significant number of vascular complications, 39% of which the majority were arterial thrombosis. Fifty per cent of those which thrombosed were salvaged on exploration and revision of the vessels. The frequency of complications has diminished with experience but they remain significantly high. Free flap surgery demands considerable expertise in both donor site dissection and microvascular technique. Two surgeons with microvascular experience, each with adequate assistance, are preferred and ready availability of operating room is essential. Close postoperative observation and readiness to revise anastomoses are equally important. About 50% of failed free flap sites have been repaired by application of split skin grafts.
在这一系列62例游离皮瓣移植手术中，48例（80%）成功。出现了大量血管并发症，其中39%主要是动脉血栓形成。血栓形成的病例中有50%在血管探查和修复时得以挽救。随着经验的积累，并发症的发生率有所降低，但仍然很高。游离皮瓣手术需要在供区解剖和微血管技术方面具备相当的专业知识。最好有两名有微血管经验的外科医生，每人都有足够的助手，并且手术室随时可用至关重要。术后密切观察以及随时准备修复吻合口同样重要。约50%游离皮瓣失败的部位通过应用分层皮片移植进行了修复。
