本文在手术显微镜下共共解剖50例挠动脉反共皮支。挠功脉浅段平均长87.35毫米,深段平均长117.34毫米。每例挠动脉平均发出14支皮支,浅段发出的皮支多于深段。起自挠动脉内侧和外侧的皮支较多,出现率接近,共中多数分别行向内下和外下,但也有呈拌状返行向上的。挠动脉皮支的管径平均为。.55毫米,从管径看深段的皮支粗于浅段的皮支,起白挠动脉外侧的皮支稍粗于内侧的皮支。自内上裸平而中点到第二、三指掌面指蹼处作一连线,该线外侧的前臂皮区,就是挠动脉皮支的分布范围,平均为62,52平方厘米。挠动脉诸皮支中,有两支大皮支(出现率为74%),管径较粗(平均0.72毫米,起点恒定,有一定的分布范围,分别起自挠动脉深段近侧和浅段外侧。讨论了前臂皮瓣的扩展和皮瓣的,心区及范围,提出了利用大皮支作为较小的前臂皮瓣的血管蒂的可能性。
In this paper, a total of 50 cases under the operating microscope dissected anti-common ancillary dermoid artery branch. The average length of the flexible meridian is 87.35 mm and the average length of the deep segment is 117.34 mm. In each case, an average of 14 branches of the radial artery were issued. The superficial skin branches were more than the deep ones. From the medial and lateral rostral artery branching more, the incidence rate is close to a total of most of the line to the inside and outside under the line, respectively, but there was also mixed with the return line up. The diameter of the artery of the artery is average. .55 mm, from the diameter of the deep branch of the dermis is thicker than the superficial branch of the dermis, the white outer branch of the dorsal rachis slightly thicker than the medial branch of the skin. From the inside bare flat and midpoint to the second, three finger palm surface refers to the web at a connection, the line outside the forearm skin, is the distribution range of the dermoid artery branch, with an average of 62,52 square centimeters. In the dermis branch of the flexible artery, there are two large skin branches (incidence rate of 74%), coarser diameter (an average of 0.72 mm, a constant starting point, a certain distribution, respectively, from the proximal and distal shallow segments of the tortuous artery Outside the segment, the expansion of the forearm flaps and the heart area and extent of the flaps are discussed, suggesting the possibility of using the large cutaneous branches as the pedicles of smaller forearm flaps.
