To investigate the blood vascular distribution of supra-genicular flap and to apply the retrograded supra-genicular flap for reconstructive surgery.
Eight fresh adult cadavers with 16 lower extremities were used for the study, by means of injecting the media of red latex into the main artery of the limb. The skin vascular architecture on the lower two thirds of each thigh was observed to decide the blood supply of this region. Fifty-two patients were also used to treat the scarring contraction of the popiteal fossa with 56 of the retrograded supra-genicular flaps, and long-term follow-ups were carried out.
From this study, it was found that there are rich blood vascular networks of the skin above the knee anteriorally, laterally and medially. The abundant vascular anastomoses were also found around the knee. The clinical application of the retrograded supra-genicular flap was successfully carried out for the treatment of the scarring contraction of the popiteal fossa. All of the flaps were survived well. Long-term results were satisfactory.
The above mentioned flap is a safe and effective flap for repair the defect of the popiteal fossa.
研究膝上皮瓣的血管分布情况，并应用逆行膝上皮瓣进行修复手术。
选用8具成年新鲜尸体的16条下肢，通过向肢体主干动脉内注入红色乳胶介质进行研究。观察每条大腿下三分之二皮肤的血管构筑，以确定该区域的血供情况。还对52例患者采用56个逆行膝上皮瓣治疗腘窝瘢痕挛缩，并进行长期随访。
本研究发现，膝前、外侧和内侧上方的皮肤有丰富的血管网络。在膝关节周围也发现了丰富的血管吻合。逆行膝上皮瓣在临床应用中成功用于治疗腘窝瘢痕挛缩。所有皮瓣均存活良好。长期效果满意。
上述皮瓣是修复腘窝缺损的一种安全有效的皮瓣。
