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...

BACKGROUND AND PURPOSE to determine the accuracy of susceptibility-weighted MRI (SWI) for the detection of arteriovenous shunting (AVS) in vascular malformations of the brain (BVM). METHODS we retrospectively identified 60 patients who had been evaluated for known or suspected BVM by both SWI and digital subtraction angiography, without intervening treatment, during a 3-year period. SWI image...

BACKGROUND AND PURPOSE Our aim was to develop 3D dynamic MR digital subtraction angiography with high temporal resolution without sacrificing spatial resolution by using sensitivity encoding for the evaluation of cerebral arteriovenous malformations. METHODS Nineteen patients with 19 angiographically proven arteriovenous malformations (16 supratentorial and 3 infratentorial) were assessed by ...

Hereditary hemorrhagic telangiectasia is an uncommon autosomal dominant disease that occurs in approximately one in 5,000 to 8,000 persons. This multisystem disorder can affect the nose, skin, gastrointestinal tract, lungs, liver, and brain. Epistaxis is the most common presenting problem, occurring in 90 percent of affected patients. Approximately 15 to 30 percent of patients with hereditary h...

Renal arteriovenous malformations (AVM) are abnormal communications between the intrarenal arterial and venous systems. These lesions may present with a wide range of signs symptoms, including hypertension hematuria. We report case 71-year-old woman incidentally diagnosis asymptomatic right renal AVM.

The complete or partial spontaneous disappearance of a cerebral arteriovenous malformation is rare. Spontaneous thrombosis in large arteriovenous malformations has been reported in only two cases. We report the case of a large arteriovenous malformation in a 17-year-old man, that thrombosed spontaneously after minor surgical manipulation and review the literature and some possible mechanisms fo...

PURPOSE We assessed the usefulness of superselective angiography in patients with micro-arteriovenous malformations. PATIENTS AND METHODS Five patients had superselective angiography for either diagnosis or treatment of brain arteriovenous malformations having a nidus of less than 1 cm. All patients presented with an intracerebral hematoma. RESULTS In one patient superselective angiography ...
