The anatomic diversity of the cerebellar arteriovenous malformations requires a classification which is more surgically informative. The selection tools like the Spetzler-Martin grading system are best suited for the cerebral arteriovenous malformations, while they are quite inaccurate for the cerebellar AVMs. For this reason, in order to define the subtypes of cerebellar arteriovenous malforma...

hyperemia: a theory for the hemodynamic complications following resection of intracerebral arteriovenous malformations. criterial care aspects regarding the treatment of patients with arteriovenous malformations in interventional neuroradiology. RN: Hypertension does not cause spontaneous hemorrhage of intracranial arteriovenous malformations.

The indications, technique, and results of embolization of arteriovenous malformations with liquid adhesive agents delivered through the anterior choroidal artery are reported. Arteriovenous malformations of the temporal lobe were found in four patients with intracerebral bleeding and two with intractable epilepsy. In five of the six, the dominant arterial feeder was the anterior choroidal arte...

BACKGROUND AND OBJECTIVES The relative merits of buttonhole (or blunt needle) versus rope ladder (or sharp needle) cannulation for hemodialysis vascular access are unclear. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Clinical outcomes by cannulation method were reviewed in 90 consecutive home hemodialysis patients. Initially, patients were trained in rope ladder cannulation. From 2004 on, a...

Arteriovenous fistulas are widely used for hemodialysis patients with end-stage renal failure. Due to the lack of suitable veins because of the arteriovenous fistulas previously opened in the upper extremity, alternative access routes are being tested. Few complications of long-term alternative arteriovenous fistulas have been reported in the literature. We report the results of surgical repair...

Pulmonary arteriovenous malformations are rare congenital abnormal connections between the pulmonary arteries and veins. The patients are usually asymptomatic [1]. Although their aetiology is unclear, it is presumed that genetic abnormalities constitute a predisposition [1, 2]. An arteriovenous malformation might cause serious complications if it remains undiagnosed and untreated [3]. We report...

in order to create an effective arteriovenous fistula (avf) in patients with sustained chronic renal failure (crf), surgeons need to become familiar with various anatomical variations of venous structures in the operating field. because of variety and different types of cubital venous anatomies, there is more than a 90% possibility of creating suitable avfs in the cubital fossa , but in the wri...

background: arteriovenous malformations are one of the most common vascular disorders of the colon. vascular disorders present as painless, high-volume rectal bleeding. case presentation: this study elucidates two rare cases of vascular disorders that are diagnosed as angiodysplasia of the left colon and cavernous hemangioma of the colon and rectum.  the chief complaint in two patients was rect...

introduction: a traumatic arteriovenous fistula (avf) after repetitive blunt trauma has not been described previously. in a 34-year-old male, the first reported case of such an injury after repetitive blunt trauma is described. case presentation: a 34-year-old gentleman presented with a non-healing ulcer near his medial malleolus. a bone scan was performed and then treated for presumed osteomye...

arteriovenous fistula is considered as a prerequisite in patients with chronic renal failure undergoing hemodialysis. the purpose of this study was to compare the effectiveness and side effects if any of native vein and synthetic grafts in these patients. from april 2002 till july 2003, a total of 37 patients were referred to us for the utilization of these grafts. in 16 out of these patients w...
