Objective: We report two cases of thrombectomy for upper extremity artery occlusion with major cerebral artery occlusion using mechanical thrombectomy devices for acute ischemic stroke.Case Presentations: Case 1 was a 79-year-old woman admitted for left internal carotid artery occlusion and left upper extremity artery occlusion. Case 2 was an 87-year-old woman admitted for left middle cerebral artery occlusion and bilateral upper extremity artery occlusion. After performing mechanical thrombectomy for the cerebral artery, we achieved good recanalization of the brachial artery using the same devices in Case 1 and Case 2.Conclusions: Thrombectomy using acute ischemic stroke mechanical thrombectomy devices for upper extremity artery occlusion is useful for recanalization.
Postoperative cerebral embolism after left upper lobectomy caused by a thrombus in the pulmonary vein stump (PVS) is a serious complication. However, it is unclear if cerebral embolism can develop after other types of lobectomy. We present a case of a 68-year-old man with cerebral embolism after left lower lobectomy with a longer PVS than normal. There were no clinically suspected sources for the thrombus except for the PVS. This thrombus seemed to have formed in the PVS. The endovascularly removed thrombus contained scattered nuclear debris around neutrophils, suggesting a physiological response caused by tissue injury.
