족배부 제1중족골 동맥분포에 관한 연구

Abstract

The foot has been used as a tissue donor source for reconstruction of defects of other parts. With recent development in microvascular surgery, many of free vascularized complex tissue grafts have been used particularly in hand reconstruction because of the similarity of the anatomy between hand and foot. Detailed information about the anatomical pattern of the first dorsal metatarsal artery is a prerequisite for a successful composite foot transfer. The purpose of this study is to report our experience and findings in tissue dissection of first dorsal metatarsal artery. The materials were 26 cases of free flap procedures and 6 cases of cadaver dissection. Referring to the Gilbert classification, 22 cases were type 1(69%), 7 cases were type II (22%), and 2 cases were type 111(6.3%). One case was of atypical type in which the superficial branch that derives from the dorsalis pedis artery does not join the first dorsal metatarsal artery distally, but ends in several cutaneous twigs.
