Key result
Colorectal surgery in lithotomy position linked to acute limb ischemia from unrecognized peripheral aneurysm thrombosis.
Why the study?
Thrombosis of unrecognized peripheral aneurysms causing acute limb ischemia during colorectal surgery in the lithotomy position had not been previously reported.
Case Report
Awareness of peripheral aneurysms prior to colorectal surgery in the lithotomy position is necessary to prevent acute limb ischemia from thrombosis.
Raises caution for unrecognized peripheral aneurysms before lithotomy colorectal surgery; leaves open whether preoperative screening prevents limb ischemia.
Colorectal surgery performed with patients in the lithotomy position resulted in acute limb ischemia due to thrombosis of unrecognized peripheral aneurysms. A search of the literature failed to find this complication reported. It is postulated that the mechanism of injury is due to calf compression in the lithotomy position and/or external iliac artery compression by a retractor. Awareness of the peripheral aneurysm prior to colorectal surgery and appropriate modification of the operative approach should prevent this complication.

Lozman et al. (1983) conducted a case report in Peripheral aneurysms. Colorectal surgery in the lithotomy position was evaluated on Acute limb ischemia due to thrombosis. Colorectal surgery performed in the lithotomy position can result in acute limb ischemia due to thrombosis of unrecognized peripheral aneurysms.
