Hemifacial spasm consists of involuntary contractions of the facial muscles, usually caused by vascular compression of cranial nerve VII , near its exit zone from the brainstem [17]. Arteriovenous malformations (AVMs) are a rare cause of this condition [2, 3]. We report a case of hemifacial spasm caused by an extensive cerebellar AVM, which was successfully treated by intravascular embolization .

Renal arteriovenous malformations are uncommon and are rarely a cause for presentation. However, they can occasionally pose life-threatening problems. We present a case of an elderly female who underwent a complete left renal artery embolization, following a difficult presentation complicated by advanced dementia and multiple comorbidities. This is the first documented case of complete renal ar...

Nasal arterio-venous malformations (AVM) are uncommon lesions. We present a rare case of huge, long standing AVM in the nasal area which was treated by angioembolization, followed by surgical excision and forehead flap reconstruction.

Purpose: Arteriovenous malformations (AVM) of the head and neck are rare anomalies, but often present with significant haemorrhage or cosmetic defects. The purpose of this study is to determine the effectiveness of embolization of each type of vascular malformation. Methods: A retrospective review was performed between January 2009 to June 2015 on 36 patients who were diagnosed vascular malform...

Objective Arteriovenous malformation (AVM) is the most common form of intracranial vascular malformations in adults. Intracranial pediatric AVMs are rare. AVM located in the vicinity of the brain stem in children are even more rare. Case report This study reports a rare case of acute obstructive hydrocephalus following aqueductal stenosis caused by an unruptured grade IV perimesencephalic art...

Spinal arteriovenous malformations (AVM) have been devided into dural (Type I), intramedullary glomus (Type II), juvenile (Type III), and perimedullary direct arteriovenous fistulae (Type IV). AVMs are usually associated with subacute myelopathy in what has been known as Foix-Alajouanine syndrome. We presented two patients with two intradural spinal arteriovenous malformations associated in wha...

Embolization of brain arteriovenous malformations (AVMs) with isobutyl 2-cyanoacrylate (IBCA) is an alternative to surgical treatment when dealing with large AVMs with multiple arterial feeders. The deposition of IBCA in the nidus of the AVM may produce an active and progressive thrombosis that may lead to complete occlusion of the nidus and/or to progressive thrombosis of the draining veins. F...

A 54-year-old female presented with a cryptic arteriovenous malformation (AVM) of the choroid plexus of the fourth ventricle causing intraventricular hemorrhage. Computed tomography and magnetic resonance imaging disclosed the lesion near the fourth ventricle, but bilateral vertebral angiograms showed no abnormalities. The preoperative diagnosis was cavernous angioma. The mass was removed compl...

Spinal arteriovenous malformations (AVMs) may be associated with sensory and motor deficits, bowel or bladder dysfunction, radicular pain or deficit, and back pain. Hemorrhage can occur in the parenchyma leading to the acute onset of symptoms. Neurosurgical resection is one of the way of treatment. Several techniques including intraoperative angiography, dye-injection and the micro Doppler meth...
