Abstract:
Objective To investigate the microcirculative route of the arterialized venous flap.Methods Selecting 15 Chinese white rabbits designed the model of arterialized venous flap by anastomosis with from the central artery to central vein.The reversed blood flow perfusion was directly observed by the "ear windows" under the microscope and,simultaneous recording the changes in the microcirculation of the flap.Results All of the flaps were alived.The structure of the capillary net in the flap was a stereo-net .In the early arterialized stage,the upstream blood flows quickly in the venule;there was no blood flowing in the capillary net with the opening of the capillary net,the reconstructed procedure of the non-physilogical microcirculation was accomplished:the arterial blood mainly flow through small vein and venule,finally arrived the capillary net.Conclusions Keep up the drainage vein free,the arterialized venousflap could be alived by reconstructed effective microcirculation through the venous system.
