Carotid artery web with fetal posterior cerebral artery variant masquerading as recurrent ipsilateral cryptogenic ischaemic strokes

Abstract

A 31-year-old woman was referred to vascular surgeons with the history of recurrent ischaemic strokes in two cerebral artery territories over a span of 1 year. On investigation, she was found to have a right internal carotid artery web, with thrombus and a fetal right posterior cerebral artery (PCA), which explained the ischaemic strokes in right middle cerebral and PCA territory. The rare association of these two infrequent entities makes the case a singular one in the medical literature. Successful surgical excision was done after multidisciplinary teamwork. The carotid web was excised as part of carotid artery endarterectomy and repaired with great saphenous vein patch angioplasty. The patient made a good recovery.
