Application of end-to-side arterial anastomosis in transplantations of free tissue flap / 中华显微外科杂志

ABSTRACT

Objective To investigate the effect of end to side arterial anastomosis in the transplantations of free tissue flap Methods The end to side arterial anastomosis were used in 47 free flaps of 46 cases in this series The arterial stomas were respectively prepared into the cross section (13/47),the inclined plane angled at 45 degree (26/47) and fish mouth shaped plane (8/47) The interrupture anastomosis and continuous anastomosis following two fixed point sutures,and the continuous anastomosis following four fixed point sutures were respectively used in 28,10 and 9 arterial anastomotic stomas Results There were not postoperative embolism in all end to side anastomotic stomas in this series During the operations the embolisms of the cutaneous branch caused by a detached mini thrombus from the anastomotic stomas were occurred in 2 cases,and the arterial crisis were eliminated by reversely milking out the detached mini thrombus All flaps survived except one due to venous embolism Conclusions It is a effective and safe method that the end to side arterial anastomosis are used in the transplantation of free flap
