Hybrid operation for symptomatic intracranial artery stenosis with proximal vascular tortuosity: report of two cases / 中国脑血管病杂志

ABSTRACT

Patient 1 was a 73-year-old female who was diagnosed as symptomatic severe stenosis of • left middle cerebral artery with left internal carotid artery tortuosity. Hersymptoms persisted despite the optimal medical therapy. Reconstruction of the left internal carotid artery was successfully performed by truncating the redundant segment and following end-to-end anastomosis, then intracranial steht was deployed via a new available approach. Patient's symptoms alleviated after operation and never reoccured in 12-month follow-up. Patient 2 was a 70-year-old male who had basilar artery severe stenosis with left vertebral artery. Tortuosity and contralateral one slendemess. He suffered from recurrent posterior circulation ischemia even with optimal medical therapy. During the hybrid operation, the left vertebral artery was exposed and cut open so that an available approach for endovascular procedure was created. No recurrence of symptoms in follow- up after operation with for 9 months. Relevant literature was reviewed. We concluded that for treatment of symptomatic severe intracranial artery stenosis with proximal vascular tortuosity, hybrid operation can be safe and effective.
