Detection of accidental leg ischemia during aortoiliac reconstruction.

Abstract

After surgery of the aorta and iliac arteries, perioperative information concerning the circulatory status of the legs is vital. In a consecutive series of 71 patients, segmental air plethysmography was used to monitor simultaneously pulse volumes in both legs. Accidental ischemia was detected in four patients, and immediate corrective measures were undertaken. Compared with other methods, plethysmography proved reliable and easy to use.
