Association between Preoperative Vascular Function and Postoperative Arteriovenous Fistula Development.
Arteriovenous fistula (AVF) maturation failure is the primary cause of dialysis vascular access dysfunction. To evaluate whether preoperative vascular functional properties predict postoperative AVF measurements, patients enrolled in the Hemodialysis Fistula Maturation Study underwent up to five preoperative vascular function tests (VFTs): flow-mediated dilation (FMD), nitroglycerin-mediated di...
متن کاملSpinal dural arteriovenous fistula : a case report
Background: Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence. Case Presentation: Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out ot...
متن کاملTesticular Arteriovenous Malformation: Gray-Scale and Color Doppler Ultrasonography Features
Intratesticular arteriovenous malformations (AVMs) are extremely rare benign incidental lesions of the testis. Ultrasonography (US) generally reveals a hypoechoic solid mass within the testicular parenchyma. We describe a patient with intratesticular AVM which was found incidentally during workup for infertility. The gray-scale and Doppler US appearance of an intratesticular AVM and the differe...
متن کاملPreoperative venous intimal hyperplasia, postoperative arteriovenous fistula stenosis, and clinical fistula outcomes.
BACKGROUND AND OBJECTIVES Arteriovenous fistulas often fail to mature, and nonmaturation has been attributed to postoperative stenosis caused by aggressive neointimal hyperplasia. Preexisting intimal hyperplasia in the native veins of uremic patients may predispose to postoperative arteriovenous fistula stenosis and arteriovenous fistula nonmaturation. DESIGN, SETTING, PARTICIPANTS, & MEASURE...
