Abstract:
Acute, unanticipated superior vena cava (SVC) occlusion during thoracic surgery can have profound hemodynamic consequences and lead to devastating neurologic injury. We describe the successful anesthetic management of a pneumonectomy complicated by prolonged intraoperative SVC occlusion lasting a total of 290 minutes. To our knowledge, this represents the longest reported SVC occlusion time with no subsequent neurologic sequelae. Based on our favorable outcome and a review of the relevant literature, we offer a discussion of strategies for anesthetic management.
