在观察的50例标本中,阴部外浅动脉多分为上、下两主支(82％),两主支来自一个阴部外浅动脉干的占66％。阴部外浅动脉干和具有独立起源的上、下主支,大都起自股动脉。动脉干或上、下主支穿入浅层的位置在大隐静脉末段的内侧缘或外侧缘,并集中在股动脉起点向内10毫米、向下50毫米为中心的一个半径为15毫米的圆内。如果动脉干、上主支、下主支与大隐静脉相遇时,动脉干和下主支多跨过静脉的后方,上主支多跨过静脉的前方。上主支主要分布于耻骨上区、耻骨前区和腹股沟内侧份。采用上主支为游离皮瓣动脉蒂时,可以用股动脉起点下50毫米处与耻骨结节间的连线作皮瓣轴。下主支主要分布于股内侧部上份和耻骨前区。采用下主支为游离皮瓣动脉蒂时,可以用股动脉起点下50毫米处作与耻骨嵴平行的线为轴。上、下主支起始处管径与分布范围密切正相关。阴部外浅静脉大都是阴部外浅动脉的伴行静脉(82％)。讨论了采用有关皮瓣的有利条件。
Among the 50 specimens observed, the extrapulmonary superficial arteries were divided into upper and lower main branches (82%) and the two main branches originated from a superficial femoral artery (66%). Genitals and superficial arteries and the independent origin of the upper and lower main branch, most from the femoral artery. Artery trunk or upper and lower main branches into the superficial position in the saphenous vein at the medial or lateral margin of the distal segment and concentrated in the femoral artery origin 10 mm inward, down 50 mm centered on a radius of 15 mm Inside the circle. If the arterial stem, the main branch, the main branch and the saphenous vein meet, the main artery and the main branch of the artery more than the back of the veins, the main branch in front of more than the veins. The main branch of the main distribution in the suprapubic area, suprapubic area and inguinal portion. The use of the main branch of the free flap pedicle, you can use the starting point of the femoral artery and pubic tuberculosis 50 mm at the connection between the shaft for the flap. The main branch of the main distribution in the stock on the side of the former and the pubic region. Using the main branch of the free flap arterial pedicle, you can use the starting point of the femoral artery at 50 mm at the parallel with the pubic crest axis. Upper and lower main branch of the beginning of the diameter and distribution is closely related to the scope. The genital superficial veins are mostly the accessory venous superficial femoral artery (82%). The favorable conditions for using flaps are discussed.
