Occipital intracranial dural arteriovenous fistula with giant venous aneurysm and ruptured temporal arterial aneurysm with intra cerebral haemorrhage – a case report

As we all know 10% of all cerebral vascular anomalies are caused by a dural arteriovenous fistula (dAVF). While these lesions may be benign, the existence of retrograde venous drainage and cerebral venous reflux puts patients at risk of bleeding, neurological impairment, and death. Endovascular therapy is commonly utilized as the first-line treatment for dAVF. Both trans arterial and transvenous techniques are utilized to treat dAVF. The treatment strategy employed is dictated on the dAVF's angioarchitecture, location, and venous flow direction. Surgery and, to a lesser extent, stereotactic radiosurgery are used when endovascular procedures are ineffective or unsatisfactory, as well as when an AV fistula is associated with a ruptured aneurysm with cerebral bleeding.
