Abstract

We report 4 cases of ischemic brain and spinal cord injury after shoulder surgery in the beach chair position, using data from medical legal case reviews. We argue that the correlation between cardiovascular risk factors and cerebral ischemic complications for this type of surgery is poor in these middle-aged patients. Rather, our analysis suggests that the sitting position and the head position create specific physiological conditions that may be conducive to cerebral and spinal cord ischemia during this type of surgery. Thromboembolic events may be an additional cause of adverse neurologic outcomes.
