摘　　要：目的为骨间后动脉皮支链皮瓣的带蒂或游离切取提供解剖学数据。方法新鲜男尸正常上肢标本14侧，分别进行乳胶灌注显微解剖、过氯乙烯和牙托材料混合填充剂制作铸型标本、聚乙烯醇一氧化铋灌注平铺x线动脉造影3种方法研究骨间后动脉皮支的解剖形态学特点。对直径0．2mm以上的皮支纳入统计分析。结果①每侧骨间后动脉发出皮支6．2支，以尺骨小头桡侧缘到肱骨外上髁的连线为标准距离．远段皮支血管丛聚集点在21．24％的位置，包含皮支3．3支，近段皮支血管丛聚集点在47．86％位置，包含皮支2．9支。②距离尺骨茎突近端（5．82±1．22）em，肱骨外上髁远端（10．34±0．98）em分别有直径为（0．50±0．04）mm、蒂长（16．79±5．12）mm和直径（0．60±0．08）mm、蒂长（21．20±12．28）mm粗大皮支从骨间后动脉发出。③相邻皮支间吻合形成与骨间后动脉平行走行的血管链。结论以骨间后动脉皮支为蒂设计的游离或者转位皮支链皮瓣有一定的临床应用价值。To provide anatomy information for harvesting a pedicle or free posterior interosseous artery cutaneous brancheschain flaps. Methods Fourteen forearms from fresh human cadaver were used to study the anatomy characteristics of the posterior interosseous artery cutaneous brancheschain flaps with the following three methods： latex perfusion for microanatomy, denture materials and vinyl chloride mixed packing for cast, and PVAbismuth oxide perfusion for molybdenum target Xray arteriography. The cutaneous perforator with a diameter ≥ 0.2 mm were included for statistical analysisResults There were 6.2 cutaneous branches raised from posterior interosseous artery. Measuring from the radial edge of ulnar head to the lateral epicondyle of humerus as the standard distance, the distal cutaneous branch clusters located at 21.24% relative to the standard distance, while the proximal clusters located at 47.86%. There were two large cutaneous perforators from the posterior interosseous artery at （5.82 ± 1.22）cm proximal to the ulnar styloid and （10.34 ± 0.98）cm distal to the epicondyle of humerus. The diameter and pedicle length of the distal perforators were（0.50 ± 0.04）mm and （16.79 ± 5.12）mm respectively, while the proximal perforator were （0.60 ±0.08 ）mm in diameter with a pedicle （21.20 ± 12.28）mm in length. The vascular chains parallel to the posterior interosseous artery were formed via anastomosis of the adjacent cutaneous perforators. Conclusion There is clinical significance to use pedicle or free posterior interosseous artery cutaneous brancheschain flaps.
