Experimental study for blood circulation route of venous skin flaps nurtured by venous blood

OBJECTIVETo study the blood circulation route of venous skin flaps nurtured by venous blood.METHODS30 Chinese rabbits were divided randomly into 2 groups. In group A (30 cases), central artery, anterior and posterior marginal veins were cut while the central vein and auditory nerve were kept. In group B (30 cases), central artery, auditory nerve, anterior and posterior marginal veins were cut, while central vein was kept. The skin flaps of group A and B were perfused with 300mL/L Chinese ink from the vein of distal end of skin flaps on 3rd, 5th, 7th, 14th and 28th day individually after operation.RESULTSLots of inks were perfused in the papillary under layer and venule net of superficial fascia.CONCLUSIONBlood circulation rout is the cardinal vein distal end, venule, venule net, venule and cardinal vein proximal end in rabbits.
