Preoperative arterial pulse pressure has no apparent association with perioperative mortality after lower extremity arterial bypass.
Arterial pulse pressure hypertension is associated with perioperative morbidity and mortality in cardiac surgery patients. However, its association with perioperative mortality in other high-risk surgical populations has not been determined. In this study, we tested the hypothesis that increased preoperative arterial pulse pressure is associated with 30-day and 1-year all-cause mortality after lower extremity arterial bypass surgery. ⋯ Our results suggest that increased preoperative arterial pulse pressure might not be associated with all-cause mortality after lower extremity arterial bypass surgery.

Case ReportsFocal cerebral ischemia after surgery in the "beach chair" position: the role of a congenital variation of circle of Willis anatomy.
A 50-year-old man underwent shoulder surgery in the beach chair position. His mean arterial blood pressure at arm level was approximately 65 mm Hg. ⋯ Radiologic evaluation revealed a congenital asymmetry of the circle of Willis that resulted in limited collateral flow to the left anterior and middle cerebral artery distributions. Similar anatomical variations are relatively common in the general population and may render some patients relatively and unpredictably more vulnerable to hypotension.
