股内侧区皮瓣的显微外科解剖

A STUDY ON THE MICROSURGICAL ANATOMY OF THE FREE FLAP OF THE MEDIAL FEMORAL REGION

观察了30侧新鲜成年尸体下肢的股内侧区皮瓣,发现口径在0.4mm以上的动脉共354支,平均每侧11.8支。股内侧区分为五段,其中第二、三段,即股内侧区中部皮瓣,此部有1~3支动脉,它的起源与走行恒定,口径在1mm的以上,定名为股内侧主要皮动脉,为此部皮瓣的轴心血管。此区的伴行静脉与皮神经也较恒定。因此作者认为第二、三段是一个理想的游离皮瓣移植的供皮区。

The free flaps of medial femoral region were studied by dissecting 30 lower limbs of fresh adult cadavers.The arteries with a caliber exceeding 0.4 mm in diameter amount to 354,averaging 11.8 branches in this region in each case.This region was divided into five segments,the first segment corresponding to the medial part of the groin region and the 4th and 5th segments corresponding to the medial part of the knee region.However,the nature of the 2nd and 3rd segments corresponding to the middle part of the medial femoral has often been overlooked.There are 1~3 arteries in this part,both their origin and course are constant and the calibers exceed 1 mm in diameter.We have named this artery as the main medial femoral cutaneous artery.The artery in this region is a constant axial vessel of the free flap and the accompanying vein and cutaneous nerves are constant too.As such,it is suggested that the 2nd and 3rd segments of the medial femoral region may serve as ideal donors in free flap grafting.
