Abstract
Parallel to a more widespread application of endovascular neurothrombectomy in acute ischemic stroke, it is critical to understand the nature and management of associated complications, including wire perforation of the middle cerebral artery (MCA). Sacrifice of the perforated vessel may be necessary to avoid fatal intra-cranial hemorrhage. Here we describe a case of right MCA distribution ischemia complicated by a right MCA perforation. Using super selective injection of contrast through a microcatheter, the point of extravasation was located and sealed with liquid embolic agent (Onyx) while preserving patency of the MCA. By avoiding vessel sacrifice, blood perfusion to distal areas was preserved and therefore the patient was discharged with minimal neurological impairment. Causes of perforation and technical aspects to control extravasation are further discussed.
