Intertwining Coil and Catheter During Brain Arterial-Venous Malformation Embolization: A Case Report of a Rare Complication.

Cerebral arteriovenous malformations (AVMs) are rare vascular anomalies associated with a risk of devastating intracerebral hemorrhage. They are often diagnosed following the appearance of seizures, focal neurological signs, or bleeding. In such cases endovascular embolization, which aims to occlude the AVM nidus and reduce risk of hemorrhage, has become a crucial therapeutic approach.
