Abstract

The viability of axial pattern skin flaps in pigs was assessed by the use of intravenous fluorescein, intradermal injection of 133Xe in saline, intravenous 51Cr tagged red cells, and angiography. The results were correlated with flap survival at 4 days postoperatively. Intravenous fluorescein provided the most accurate method for prediction of viable tissue at the time of operation. There was no evidence of vascular perfusion in the distal portions of these flaps. These axial pattern flaps differed in their viability from similar flaps in humans, and anastomoses between discrete vascular territories were infrequent in pigskin.

摘要

通过静脉注射荧光素、皮内注射生理盐水稀释的¹³³Xe、静脉注射⁵¹Cr标记的红细胞以及血管造影术，评估猪轴型皮瓣的活力。将结果与术后4天皮瓣的存活情况进行关联分析。静脉注射荧光素为术中预测存活组织提供了最准确的方法。这些皮瓣远端无血管灌注迹象。这些轴型皮瓣的活力与人类相似皮瓣不同，猪皮中不同血管区域之间的吻合很少见。
