Скачать или смотреть Digital Subtraction Angiography During Surgery

A 65-year-old man with uncontrolled hypertension, coronary artery disease, and heavy smoking presented to the emergency department with somnolence and left-sided hemiplegia. Angiography revealed stenosis of the right internal carotid artery and occlusion of right middle cerebral artery. After carotid artery stenting, the angiography catheter was placed in the right internal carotid artery. After mechanical thrombectomy of the right middle cerebral artery, angiography showed a filling defect in the middle cerebral artery, which moved from the segment where the lenticulostriate artery branched to the distal. The filling defect led to delayed perfusion of the distal artery. Repeat retrieval was attempted, and a piece of gray tissue was extracted, which was identified as arterial wall tissue through histopathological analysis. The right middle cerebral artery was recanalized. Normal distal perfusion followed.
