Arteriovenous FistulAs versus Arteriovenous GrAFts
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...
متن کاملAccess flow reduction and recurrent symptomatic cephalic arch stenosis in brachiocephalic hemodialysis arteriovenous fistulas.
BACKGROUND Recurrent cephalic arch stenosis (CAS) has been linked to high flow and has a high rate of recurrence following angioplasty. This study investigates the effectiveness of access flow reduction in decreasing rapidly recurrent symptomatic CAS. METHODS A retrospective study of patient records from February 2005 to April 2009 was conducted. Patients with brachiocephalic fistulas who had...
متن کاملSpinal Arteriovenous Fistulas
Several classifications have been proposed for spinal AVMs.[2],[4]-[6] They can be divided into intramedullary AVMs and arteriovenous fistulas (AVFs). Based on anatomical characteristics, spinal AVFs are classified as extradural AVFs and intradural lesions, including spinal dural AVFs (SDAVFs) and perimedullary spinal AVFs (PMAVFs).[7],[8] Rangel-Castilla et al. classified extradural AVFs as ty...
متن کاملCongenital Arteriovenous Fistulas
Arteriovenous fistulas of the thoracic wall may produce murmurs and thrills which suggest an intrathoracic vascular abnormality. Congenital arteriovenous fistulas in the plecordial region, the site of the fistula in the case here reported, may be confused with anomalies of the heart and great vessels. The differential diagnosis of blood vessel tumors of the chest wall is discussed. Occasionally...
متن کاملSpinal dural arteriovenous fistulas.
Spinal dural arteriovenous (AV) fistulas are the most commonly encountered vascular malformation of the spinal cord and a treatable cause for progressive para- or tetraplegia. They most commonly affect elderly men and are classically found in the thoracolumbar region. The AV shunt is located inside the dura mater close to the spinal nerve root where the arterial blood from a radiculomeningeal a...
