摘要
我院应用４例前臂动脉他静脉皮瓣及离体标本的灌注，探讨了此皮瓣的血循环机理。动脉血经静脉支部分直接回流，部分进入微静脉经毛细血管达真毛细管网。另部分动脉血入微静脉经动静脉吻合支返回微动脉入后微动脉再入真毛细血管网。因静脉瓣的阻碍，使引流侧皮瓣远端灌流困难，易造成缺血坏死而灌流侧易成瘀血性坏死。因此理想血供应是动脉化干及引流干均应顺静脉血流方向缝接．减少静脉瓣阻力。动脉化静脉皮瓣易发生肿胀、充血、瘀血，质地须较长时间才能恢复正常。但是，此皮瓣来源多，不须牺牲知名动脉，适当病例可选用。
Abstract Our hospital applied 4 cases of arterlalized venous skin flap in the forearm and also done experiment with vascular infusion. We found that the arterial blood circuited,direct partly through branches of vein and partly into capillary network through micro vein. Some also flew through micro vein and microartery into capillary nctwork. The hlock of venous volve was likely to cause iscemic necrosis in the distal aspect of the flap and hlood extravasation in the proximal aspect. So thevessels should be anastomosed according to the direction of venous flow. With more available donor sites and no sacrificeof named artery, this method is still applicable in suitable cases despite high occurrence of swelling, congestion, blood ex travasation and prolonged period for quality recovery.
