Abstract

|
Cerebral embolic stroke caused by a thrombus in the pulmonary vein stump after left pulmonary lobectomy is a serious complication. We retrospectively analyzed four patients who underwent mechanical thrombectomy for large-vessel occlusion after left pulmonary lobectomy between January 2014 and March 2022. Two cases occurred after left upper lobectomy and the others occurred after left lower lobectomy. All patients presented with cerebral embolic stroke from the day after surgery to the 9th postoperative day, and successful reperfusion was achieved in all cases. Two patients had good outcomes at 90 days. Thrombus in the pulmonary vein stump is the probable cause of cerebral embolism, and mechanical thrombectomy is effective. Further studies are required to establish preventive measures and perioperative management strategies.
