the possibility of abnormal avf was considered and it was confirmed on contrast-enhanced computed tomography (ct), inferring that this modality is not only fast and non-invasive, but also accurate in detecting vascular abnormalities. herein, we report a 42-year-old woman with congenital avf between the external carotid artery and external jugular vein, presenting with palpitation and dyspnea. t...

We report two rare and infrequent cases, one of a patient with Cognard type V tentorial dural fistula diagnosed at the beginning as trunk glioma in gait disturbance. And another Guillian Barré syndrome tetraparesis secondary to arteriovenous fistula.

BACKGROUND The patency of arteriovenous access is important for stable and effective hemodialysis, and long-term technical survival is best achieved with a native arteriovenous fistula (AVF). However, maintaining AVF patency remains a challenge. This study was designed to determine the independent prognostic factors for AVF patency according to hemodialysis duration. METHODS The primary study...

In repairing coronary arteriovenous fistula (CAVF), it is very important to interrupt the fistulous tract without compromise of normal coronary vessel flow. In our case, selective coronary arteriography showed that the CAVF from the left anterior descending coronary artery (LAD) was very close to the native coronary artery and had a very broad and short neck. We describe a simple and useful app...

Arteriovenous fistula presents rarely with ascites. Diagnosis, with an elusive clinical presentation, is often incidental or delayed. A 35-year-old woman presented with ascites and cardiac decompensation. Contrast enhanced computed tomography revealed arteriovenous fistula between the left common iliac artery aneurysm and the left common iliac vein. The patient underwent endovascular treatment ...

AIM To assess the survival of the primary arteriovenous fistula created for dialysis in 463 chronic hemodialysis patients, because the main causes of morbidity among such patients are associated with vascular access-related complications. METHOD We analyzed 269 (58%) men and 194 (42%) women with median age of 58 years (range 12-83), who underwent 0-14,784 (median 1,584) hours of hemodialysis....

conclusion for more precise prediction of successful aavf maturation after spta, short-term follow-up doppler ultrasonography (< 2 weeks) was useful. if the asr was < 0.7 or if residual stenosis was ≥ 30%, immediate repeat spta is recommended. results the technical and clinical success rates were both 94.9% (56/59); the mean asr was 0.84. an asr of ≥ 0.7 and no significant residual stenosis (< ...

background & aim: arteriovenous fistula (avf) is one of the inevitable elements in the take care of patients on hemodialysis. pain of avf puncture is a real problem for patients. the purpose of this study was to assess the effect of inhalation of lavender aromatherapy on pain intensity of arteriove-nous fistula puncture in patients on heamodialysis. methods & materials: in this before and after...

background the presence of arterio-venous (a-v) fistula recirculation among hemodialysis (hd) patients markedly decrease adequacy of dialysis. objectives the present article summarize some of observations about clinical significance, causes, the most common techniques for measurement, and main source of pitfall in calculation of access recirculation. materials and methods a variety of literatur...
