Abstract
A man in his early 80s presented with acute onset aphasia and right-sided weakness with an NIH Stroke Scale (NIHSS) of 17. He was last seen normal 9 hours before the presentation. MRI of the brain showed acute infarcts in the left caudate, lentiform nucleus and corona radiata. MRI angiogram (MRA) revealed an occluded left main middle cerebral artery (MCA) and an associated ipsilateral patent duplicated middle cerebral artery (DMCA). Mechanical thrombectomy (MT) was performed, and he was discharged with an NIHSS of 8. In this report, we review and discuss the challenges during the intervention of MCA occlusion in the presence of duplicated MCA, a rare anomaly.
