Arteriovenous graft for hemodialysis vascular access is a widely used technique with many advantages. However, it has crucial complications with graft thrombosis and infection. We recently experienced an unusual case of arteriovenous graft complication involving graft thrombosis related to fistula formation between the graft and the natural vein with infection. We diagnosed this condition using...

We present a case of developmental venous anomaly associated with arteriovenous fistula supplied by a single arterial feeder adjacent to a large acute intracerebral hemorrhage. The arteriovenous fistula was successfully obliterated by superselective embolization while completely preserving the developmental venous anomaly. Two similar cases, including superselective angiographic findings, have ...

Pulmonary arteriovenous fistulas (PAVFs) are rare vascular malformations (PAVMs) of the lung that could lead to severe hypoxiemia due to right-to-left intrapulmonary shunts. They may occur as isolated entities or associated with Osler-Rendu-Weber syndrome or hereditary haemorrhagic telangiectasia (HHT). We study 3 patients with Rendu-OslerWeber disease and a large arteriovenous malformation inv...

Primary intraosseous arteriovenous malformations (AVM) are not infrequently encountered. We report a case of intraosseous arteriovenous malformation arising in the left temporal bone. A 51-year-old male patient presented with loss of conscious. Computerized tomography displayed hematoma measuring 4 cm in diameter in the left temporal lobe. Digital subtraction angiography (DSA) showed that a tem...

A 35-year-old man suffered secondary generalized tonic-clonic convulsions due to a large brain abscess. Neuroimaging incidentally revealed another tumor-like lesion. Cerebral angiography confirmed that the lesion was an unusual giant venous varix associated with a high-flow pial arteriovenous fistula (AVF) and showed one more small arteriovenous malformation (AVM). Pulmonary AVF, which can caus...

Pulmonary arteriovenous fistulas (PAVFs) are rare vascular malformations (PAVMs) of the lung that could lead to severe hypoxiemia due to right-to-left intrapulmonary shunts. They may occur as isolated entities or associated with Osler-Rendu-Weber syndrome or hereditary haemorrhagic telangiectasia (HHT). We report a case of a 70 years old woman with Rendu-Osler-Weber disease and a large arteriov...

BACKGROUND Vascular malformations with arteriovenous shunt components can cause significant disability, chronic pain, and functional impairment. Effective treatment may require serial procedures, yet an imaging modality optimized to control cost and reduce radiation exposure in this predominantly pediatric population has not yet been identified. METHODS AND RESULTS We describe the use of cont...

Diffuse cerebral arteriovenous malformation (AVM) is a rare disorder of the brain and defined as diffuse infiltration of brain by complex vascular structures. It is usually associated with hereditary syndromes and presented with hemorrhage or seizure. We report a 20-year-old male patient who presented with drooping of the left eyelid. He had no skin lesion. The ophthalmological examination was ...
