Double-Barrel (2-Donor-2-Recipient) Bypass as Rescue Treatment for Patient with Occluded Middle Cerebral Artery Intracranial Stent and Recurrent Ischemia.

Stent occlusion is a challenging complication following endovascular interventions that require intracranial stenting. Although there are small series describing revascularization for stenoocclusive disease failing best medical management, there are few reports in the literature regarding surgical bypass as a treatment for stent occlusion. We present the case of a 37-year-old man who presented with right-sided weakness, numbness, and difficulty with speech and ambulation. His history is notable for a left M1 (segment of middle cerebral artery) occlusion 6 months prior that was treated with mechanical thrombectomy requiring repeat thrombectomy and rescue acute middle cerebral artery (MCA) stent placement given vessel reocclusion. Diagnostic cerebral angiography demonstrated stent occlusion. Given his continued ischemic symptoms despite best medical management, the patient underwent a double-barrel superficial temporal artery-MCA direct bypass to revascularize the MCA territory. To our knowledge, there is no literature to date describing a 2-donor-2-recipient direct bypass for the rescue treatment of symptomatic intracranial stent occlusion with recurrent ischemia. We review the case presentation, angiographic findings, surgical nuances, and postoperative course with imaging. The patient provided informed consent for the procedure and verbal support for publishing his image and inclusion in this submission.
