摘　　要：目的:通过对浅静脉干的形态学和血流动力学观察,探索浅静脉干促进逆行皮瓣静脉回流的机理,进一步指导带浅静脉干逆行皮瓣的临床应用。方法:用小鼠耳制成带浅静脉干的逆行皮瓣模型共48例,每个皮瓣内只有一条浅静脉干,用微循环观察仪对浅静脉干进行形态学和血流动力学观察。结果:根据形态可将逆行皮瓣中的浅静脉干分为3种类型:“I”形,“Y”形和树枝形,各种类型的浅静脉干都是皮瓣静脉逆向回流的主要通道,如果在蒂部将浅静脉干闭塞,皮瓣的静脉回流基本停滞。结论:浅静脉干的存在有助于逆行皮瓣的静脉逆向回流,并在回流中起类似“枢纽”的重要作用,临床应尽量选用“I”形浅静脉干。Objective Through morphological and haemodynamical observation of superficial venous trunks, to explore the mechanism of how the superficial venous trunks improve the venous drainage of reverse-flow flaps and further guide the clinical application of reverse-flow flaps pedicled with superficial venous trunks. Methods 48 reverse-flow flap models pedicled with superficial venous trunks were performed in ears of mice. The morphology and haemodynamics of the superficial venous trunks were observed by microcirculative meter. Results According to morphology, there were 3 types of superficial venous trunks in the flaps： “I” type, “Y” type and branch type. All types of the superfical venous trunks were the major passages in the venous drainage of the flaps. If the superficial venous trunks were occluded in pedicles, the venous drainage of the flaps almost stoped. Conclusion Superficial venous trunks act as “hinges” to improve the venous drainage of reverse-flow flaps, and play important roles in the venous drainage. “I” type superficial venous trunks are most effective and should be chosen in the clinical application.
