Interventional treatment for acute cerebral infarction with large vessel occlusion combined with aortic arch interruption

Abstract Rationale: Aortic arch interruption is a type of congenital vascular malformation that is often observed in childhood. Most children die of congestive heart failure due to rapid deterioration. Children can only survive to adulthood if they have extremely rich collateral circulation. Cases of acute cerebral infarction with large vessel occlusion receiving interventional treatment in adult patients with interrupted aortic arch have not been reported. Patient concerns: A 55-year-old man with a history of atrial fibrillation and smoking but without a family history of stroke was admitted to our hospital with a 5-hour history of left limb weakness and speech difficulties. Diagnoses: Emergency brain computed tomography showed a large cerebral infarction in the right frontal temporal parietal lobe. He was suspected to have aortic arch interruption in the early stage of endovascular interventional therapy through the femoral artery approach, and was converted to the transradial artery pathway. The aortic arch was disconnected, and the right internal carotid artery was occluded. Interventions: Considering the possibility of cardiogenic embolism, a middle catheter was used for thrombus aspiration of the right internal carotid artery. After removal of the dark red thrombus was removed, the right internal carotid artery was successfully recanalized. Outcomes: The patient recovered well after the operation. However, the patient and his family refused further treatment for aortic arch interruption. The modified Rankin Scale score was 0 at 3 months and 1 year of follow-up which meant that he recovered quite well. Lessons: Adult patients with acute cerebral infarction with large vessel occlusion are rarely complicated with aortic arch interruption, and emergency thrombectomy via the radial artery approach is feasible.
