In a series of 37 free composite tissue transplantations performed to the lower extremity in 34 patients, skin islands were included in 35 cases, as a cutaneous island flap (3), as a musculocutaneous island flap (19), and as an osteocutaneous island flap (13). In a follow-up study which included 26 patients with 29 flaps 6-48 months postoperatively an estimate was made of the importance of the blood supply through the vascular pedicle relative to the collateral blood supply through the recipient bed. Using transcutaneous oxygen tension measurements a significant reduction in calculated relative skin blood flow averaging 70% (p much less than 0.01) was seen after digital occlusion of the vascular stalk, suggesting that patent microvascular anastomoses are important for the vascularity of the transplanted tissues, not only for immediate postoperative survival, but also on the longer view.
在对34例患者下肢进行的37次游离复合组织移植系列手术中，35例包含皮岛，其中作为皮岛皮瓣3例、肌皮岛皮瓣19例、骨皮岛皮瓣13例。在一项随访研究中，纳入了26例患者的29个皮瓣，术后6至48个月，评估了通过血管蒂的血供相对于通过受区床的侧支血供的重要性。通过经皮氧分压测量发现，在数字阻断血管蒂后，计算得出的相对皮肤血流平均显著降低70%（p远小于0.01），这表明通畅的微血管吻合对移植组织的血管形成很重要，不仅对术后即刻存活很重要，从长远来看也是如此。
