Local blood flow regulation on the forefoot was studied by the 133Xe wash-out technique in twenty-seven patients before and after arterial reconstruction for occlusive arterial disease. In thirteen limbs with severe symptoms the local vasoconstrictor response to increased venous pressure was absent preoperatively, as blood flow in the foot increased in median by 47% when the foot was lowered 40 cm below the heart. Three months postoperatively the vasoconstrictor response had returned as blood flow decreased 28% during lowering. Fourteen limbs with milder symptoms had a vasoconstrictor response before operation. In nine limbs of this group treated with aortoiliac reconstruction the vasoconstrictor response was absent at the early postoperative examination, but the response returned till the late examination. It is concluded that the local vasoconstrictor response is normalized after arterial reconstruction. Disturbances may, however, occur in the postoperative period, possibly due to operative stress.
采用¹³³Xe清除技术，对27例因闭塞性动脉疾病接受动脉重建术的患者术前和术后前足局部血流调节情况进行了研究。在13例症状严重的肢体中，术前对静脉压升高缺乏局部血管收缩反应，当足部低于心脏40厘米时，足部血流平均增加47%。术后3个月，血管收缩反应恢复，足部下垂时血流减少28%。14例症状较轻的肢体术前有血管收缩反应。在该组接受主-髂动脉重建术治疗的9例肢体中，术后早期检查时血管收缩反应消失，但在晚期检查时反应恢复。得出结论：动脉重建术后局部血管收缩反应恢复正常。然而，术后可能会出现紊乱，这可能是由于手术应激所致。
