Thirty-four patients with angiographically proved arteriovenous malformations of the spinal cord were studied between May 1986 and July 1987. Examinations were performed on a CGR 5000 Magniscan 0.5-T scanner with a surface coil in all cases, and multislices in both T1- and T2-weighted sequences were obtained in sagittal and axial planes. The results showed that MR can accurately diagnose all ca...

The technical feasibility of selective intranidal endovascular occlusion of experimental arteriovenous malformations with detachable superfine platinum electrodes was assessed in a swine model. The delivery and release of electrodes were performed within normal carotid retia mirabilia, the faster-flowing nidus (bilateral retia) of a carotid-jugular fistula-type model of an arteriovenous malform...

PURPOSE To examine the clinical and radiographic findings in a large group of patients having or suspected of having a spinal dural arteriovenous fistula. METHODS An analysis of 240 spinal angiograms in 132 patients revealed 97 vascular malformations that included 66 spinal dural arteriovenous fistulas. Sixteen patients had 1 or more normal spinal angiograms that were performed for suspected ...

PURPOSE To report the comprehensive superselective angiographic characteristics of aneurysms associated with cerebral arteriovenous malformations. METHOD One hundred consecutive patients referred for cerebral arteriovenous malformation embolization underwent preembolization superselective angiography. Superselective angiograms were obtained after microcatheterization of arteriovenous malforma...

Previous studies of the uptake and release of free fatty acid (FFA) of various tissues (1, 2) have indicated that during the basal state there is usually a net release of FFA from the leg, but a more variable response in the forearm. This variability of forearm arteriovenous FFA differences has raised the issue of whether or not arteriovenous differences of total FFA alone provide an accurate i...

Fetal heart failure and hydrops fetalis may occur due to systemic arteriovenous fistula because of increased cardiac output. Arteriovenous fistula of the central nervous system, liver, bone or vascular tumors such as sacrococcygeal teratoma were previously reported to be causes of intrauterine heart failure. However, coronary arteriovenous fistula was not reported as a cause of fetal heart fail...

BACKGROUND Isolated congenital asplenia is a poorly understood and rare form of primary immunodeficiency, often associated with life-threatening infections. CASE REPORT We encountered a unique case of a 22-year-old asplenic male who presented with severe iron-deficiency anemia secondary to occult gastrointestinal bleeding since age 15. Our extensive work-up confirmed jejunal arteriovenous malfo...

PURPOSE To determine the potential and limitations of MR angiography in the evaluation of spinal vascular malformations. METHODS Eleven consecutive patients with spinal vascular malformations proved with spinal selective arteriography underwent two-dimensional phase-contrast MR angiography. RESULTS Abnormal vessels within the spinal canal were identified with MR angiography in 10 patients. ...

BACKGROUND Oroantral fistulas are pathologic connections between the oral cavity and the maxillary sinus. Arteriovenous fistulas are abnormal connections between an artery and a vein with no intervening capillary network. METHODS We present an extremely rare case of barotrauma-related oroantral fistula with an associated arteriovenous fistula between the internal maxillary artery and the opht...

Abstract Introduction: Arteriovenous fistula dysfunction has been associated with a range of problems such as thrombosis, stenosis, dilatation, and infection. Case presentation: We present the case 64-year-old patient chronic kidney disease on hemodialysis aneurysmal dilatation ulnar-basilic arteriovenous fistula, having an increased risk rupture. A temporary dialysis catheter is placed in left...
