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...

Intravascular migration of bullets and other foreign bodies is a rare but known complication of penetrating trauma. Missile embolization can represent a diagnostic challenge because it may present in various and unexpected ways. We present the case of a 54-year-old female who sustained shotgun pellet emboli to the pulmonary arteries following a left upper extremity gunshot wound and related vas...

The technique with a wing microcatheter system and the pathologic aspects of 11 cerebral arteriovenous malformations (AVMs) surgically resected after embolization with polylene threads are reported. Embolization was performed once in eight patients and twice in three patients. Resected AVMs were submitted both to routine hematoxylineosin examination and to immunohistochemical workup in order to...

patients and methods tae was performed on 20 patients with liver hemangioma. the embolic agent used was polyvinyl alcohol (pva) particles (300-400 micron, jonson and johnson cordis, usa). all patients were followed up for 6 months. imaging was carried out and patients were also evaluated symptomatically through telephone interview by a physician. results twenty patients aged from 21 to 63 years...

BACKGROUND The liver is the predominant site of metastases among patients with advanced neuroendocrine tumors (NETs). Prior retrospective studies have reported high response rates in patients treated with transarterial embolization (TAE). NETs are highly vascular and are known to express vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor (VEGFR). We hypoth...

Abstract Background Indirect carotid-cavernous fistulas (CCF) are dural arteriovenous fistula of the cavernous sinus and generally present with ocular symptoms. High index clinical suspicion radiological work up is required for diagnosis, treatment primarily endovascular embolization. We our experience in diagnosis management indirect CCF along technical evolution to perform embolization differ...

We present the case of a five-year-old boy with a caroticoazygous fistula, which is an extremely rare congenital vascular malformation. The patient also had patent ductus arteriosus, a common cause of continuous murmur. The murmur continued despite successful coil embolization of the ductus. Repeated catheter-angiography revealed a large caroticoazygous fistula. The fistula was successfully emb...

Congenital coronary artery fistula is an uncommon anomaly. Transcatheter coil embolization or Amplatzer vascular plug device closure of fistula is often done in symptomatic patients with safe accessibility to the feeding coronary artery. Embolization of Amplatzer vascular plug device is rare. We report an 11-year-old male child who presented to us with increasing shortness of breath for 7 years...
