弧形阴茎阴囊联合皮瓣设计的解剖学基础

Anatomic basis of designing the arc penoscrotal skin flap

目的：为弧形阴茎、阴囊联合皮瓣的设计提供解剖学基础。方法：采用显微解剖、皮瓣血管透明、Ｘ线造影等方法，对３６侧阴茎和阴囊外侧皮瓣的血供来源、动脉主干走行、分支分布及吻合进行观测。结果：阴茎和阴囊外侧皮瓣的血供分别来自阴茎背浅和阴囊前动脉，前者起点外径为０．８±０．２ｍｍ，行于阴茎浅筋膜的疏松组织层。在阴茎阴囊交界区，两动脉的分支相互吻合。阴茎皮瓣的静脉回流有二套，其中阴茎背浅静脉为血液回流的主要血管。结论：阴茎、阴囊交界区动脉间有吻合，可设计成阴茎阴囊弧形联合皮瓣。该型皮瓣较长，足以满足重度尿道下裂的修复。

bjective:To provide anatomic basis for design the arc penoscrotal skin flap.Methods:The origin、course、branch、distribution and anastomosis of the arteries to the penile and lateral scrotal flap were observed in 18 adult male specimens by microanatomy,angiography and skin vascular transparency.Results:The artery to the penile and lateral scrotal skin is originated from the superficial dorsal penile and anterior scrotal artery respectively.The external diameter of artery to the penile is 0.8±0.2 mm and running subcutaneously.The two arterial perforators anastomose each other in the region between penis and scrotum.There are two venous vessels in penile flap.The superficial dorsal penile vein is the main vessel of the venous drainage.Conclusions:The arc penoscrotal skin flap could be designed based on the arterial anatomosis in this region and this flap is long enough for the repair the severe urethroplasty.
