Intracranial stenting after tumor exeresis complicated by delayed kinking of the middle cerebral artery

During intracranial tumor resection, the delayed kinking of a major encased vessel has never been described in literature. We present a case which required urgent endovascular treatment performed through a stent positioning. A patient was hospitalized with symptomatic sphenoid meningioma in the left middle cranial fossa. Twelve days after surgery, right-sided hemiplegia and aphasia occurred. Digital subtraction arteriography revealed a kinking of the M1 segment of the left middle cerebral artery and diffuse vasospasm. At first, intra-arterial nimodipine has been administered, obtaining the remission of the vasospasm. Secondly, a stent was positioned to treat the kinking, achieving a complete flow restoration.
