Intravascular occlusion by various catheterization techniques was used to treat 27 cases of carotid-cavernous fistula, giant intracavernous aneurysm, and cerebral or dural arteriovenous malformation. Several case reports are presented. The detachable balloon technique proved valuable in the treatment of traumatic carotid-cavernous fistula and giant aneurysm. Calibrated-leak balloon catheterizat...

A 43-year-old male presented with daytime sleepiness at work and indifferent behavior like never before. Two weeks prior to hospital admission, he had episodic memory loss with well preserved remote memory. Brain MRI showed a dural arteriovenous fistula (DAVF) in the right lateral transverse sinus with a bilateral thalamic venous infarction. Cerebral angiography confirmed a right transverse sig...

THE collateral circulation that develops invariably in the vicinity of a systemic arteriovenous fistula has impressed generations of surgeons who have treated these lesions. Investigators in various surgical modalities have sought to apply this principle to enhance the blood supply of specific regional tissue. The most successful application to date has been the creation of femoral arteriovenou...

Spinal dural arteriovenous fistulas (SDAVF) account for about 70% of all spinal AV shunts. We report on a 56-year-old male patient with progressive neurological symptoms. Preand post-contrast MR imaging of the spine, including contrast-enhanced MR angiography was done on a 1.5 T MR scanner. In addition a special (pre-contrast) 3D turbo-spin-echo sequence with variable flip angle evolution (SPAC...

PURPOSE To show that postgadolinium three-dimensional time-of-flight MR angiography shows abnormal intradural vessels associated with spinal dural arteriovenous fistula better than routine MR imaging and provides screening information useful for subsequent diagnostic conventional angiography and/or posttreatment evaluation. METHODS Precontrast and postcontrast MR imaging and MR angiograms, as...
