Bilateral Middle Cerebral Artery Occlusion: A Successful Case of Bilateral Thrombectomy

Abstract

Single-vessel occlusions often cause an acute ischemic stroke (AIS) but can rarely be caused by multi-vessel occlusions. Although bilateral AIS is rare, these patients often undergo mechanical thrombectomy as long as they are within the 24-hour window since symptom presentation. We present a case of a female in her 70s who presented to an outside facility with right-sided weakness in her upper and lower extremities, drooping of the right lower face, and aphasia. The patient developed bilateral symptoms on transfer to a tertiary center with neuro-interventional capabilities. Due to concern for a possible bilateral stroke, magnetic resonance imaging was ordered and was remarkable for bilateral middle cerebral artery occlusion. The patient underwent a successful bilateral mechanical thrombectomy within 24 hours of the last known normal. This case demonstrates that mechanical thrombectomy is an excellent treatment option for patients with bilateral occlusions that present within the recommended 24 hours from the last known normal.
