The association of intracranial hypertension and arteriovenous malformations is described in two patients. Both patients had the typical clinical features of pseudotumour cerebri and were found to have intracranial arteriovenous malformations on arteriography. The mechanism of raised intracranial pressure in patients with arteriovenous malformations is discussed.

OBJECTIVE To evaluate the occurrence of pulmonary arteriovenous malformations after a Fontan operation in the left isomerism and absent inferior vena cava. METHODS We retrospectively reviewed 19 patients with the left isomerism and absent inferior vena cava who underwent Fontan operations at our institution. We divided the patients into two groups: bilateral superior vena cava (group A, n=9),...

BACKGROUND & AIMS The success of home parenteral nutrition (HPN) programs is compromised by complications of central venous catheters (CVCs), such as occlusions and bloodstream infections. We performed a retrospective analysis of complication rates of arteriovenous fistulae versus CVCs in patients on long-term HPN. METHODS Data were collected from 127 consecutive patients who received HPN bet...

background hemangioma is the most common tumor of neonatal period and it is almost always appeared by the end of the first week of life and can be found mostly in head and neck area. this study evaluated the synergistic effect of bleomycin, triamcinolone and epinephrine in treatment of hemangioma and arte-riovenous malformations. methods in this multicenter study, a combination of bleomycin, tr...

For the nephrologist and surgeon, maintaining vascular access is a significant challenge in hemodialysis (HD), because the portal is vulnerable to infection, stenosis, and thrombus. Vascular access options for HD include the placement of arteriovenous (AV) fistulas, AV grafts, and double-lumen, cuffed central vein catheters. Catheter use is generally associated with higher rates of infection an...

Each of two patients presented with a dural arteriovenous fistula involving the transverse sinus. The sinus was thrombosed proximal and distal to the dural arteriovenous fistula with the venous drainage being retrograde through cortical veins. An ipsilateral percutaneous transjugular approach was used in both cases and allowed recanalization of the thrombosed sinus and embolization of the dural...

CONTEXT Pancreatic arteriovenous malformations are a rare entity that can be incidentally discovered during MDCT examinations. CASE REPORT We describe a rare case of asymptomatic arteriovenous malformation presenting at MDCT as a hypervascular mass in the pancreatic head. CONCLUSION Pancreatic arteriovenous malformations are a rare entity, often asymptomatic, that can be correctly diagnosed...

The literature regarding arteriovenous malformations of the external ear is sparse. A case of a patient clinically diagnosed with an arteriovenous malformation of the external ear that was managed empirically with surgical excision, without recurrence, is presented. The pathogenesis, clinical presentation, radiological work up and management options regarding arteriovenous malformations are rev...

We report an uncommon clinical case of multiple, diffuse pulmonary arteriovenous fistulas that occurred during childhood. A 15-year-old Japanese girl with multiple pulmonary arteriovenous fistulas presented with moderate hypoxemia and was treated by left lower lobectomy for complete resection of the arteriovenous fistulas. Clinical and radiographic features are presented.

A unique case of recurrent brain abscess as the primary manifestation of pulmonary arteriovenous fistula is presented. In the absence of hematologic abnormalities and characteristic physical findings, the diagnosis of pulmonary arteriovenous fistula is particularly elusive. Patients with brain abscess must be carefully evaluated for the presence of pulmonary arteriovenous fistula or hereditary ...
