Beach Chair Position in a Patient With Subclavian Steal Syndrome and Axillary Lymph Node Dissection: A Case Report.

A patient presented for elective shoulder arthroscopy who had subclavian steal syndrome. The patient's history included bilateral mastectomy with unilateral lymph node dissection, limiting noninvasive oscillometric blood pressure monitoring on the nonoperative side. This history, combined with the necessary surgical positioning and calf blood pressure monitoring, raised the concern of decreased cerebral perfusion during a general anesthetic in the beach chair position. This report describes the management of this particular case, then reviews the relevant literature regarding cardiovascular and cerebral perfusion monitoring.
