摘　　要：目的探讨血管外径与皮瓣成活面积的关系。方法采用成年家犬后肢,制备穿支蒂隐神经营养血管皮瓣模型,测量皮瓣蒂部血管外径,于一侧后肢观察不同时间点皮瓣成活情况,测量皮瓣成活比例,在另一侧后肢灌注造影,测量皮瓣造影墨染比例。结果犬下肢腓动脉内踝上穿支外径为(1.0±0.1)mm,皮瓣面积为(287.0±44.2)cm2,成活区面积为(156.6±13.6)cm2,成活比例为(55.9±9.1)%,墨染面积为(168.2±16.4)cm2,占皮瓣面积的(59.9±10.0)%。结论血管外径变大,血流量相对增加,皮肤血供范围增大,相应皮瓣成活面积也增大。该方法建立的穿支蒂隐神经营养血管皮瓣模型,可以较好的通过灌注造影面积预测出外径与皮瓣成活面积之间的关系。Objective To explore the relationship of arterial vascular caliber and flap survival area of skin flap.Methods Bilateral hind limbs of adult dogs were used to make flap model pedicled with perforating branches of saphenous neurocutaneous vessels.The diameters of the pedicled arterial vessel were measured.On one side,the flap survival at different time points were measured and compared,as well,another side was perfused black ink for measure the proportion of perfusion.Results The diameter of perforating branches of peroneal artery on the medial malleolus was（1.0±0.1） mm,and the flap area（287.0±44.2） cm2.The survival area was about（287.0±44.2） cm2,which accounted for（55.9±9.1）% of the total flap area.The perfusion imaging area was（168.2±16.4） cm2,which accounted for（59.9±10.0）%.Conclusions The survival of the flap will be supported by the wide vessels,abundant blood flow,and extensive blood supply scope.By evaluating perfusion area,the pedicled vessels and corresponding flap survival can be estimated.
