Analysis of clinical effect and complication prevention and treatment of autogenous arteriovenous fistulas stenosis by intravenous intervention therapy / 中国综合临床

ABSTRACT

Objective:To explore the clinical effect and safety of interventional treatment of autogenous arteriovenous fistula(AVF) stenosis.Methods:From July 2017 to September 2018, 96 patients with arteriovenous fistula stenosis and occlusion admitted to Handan First Hospital, Hebei Province were retrospectively analyzed.All of them were dialysis patients with chronic renal failure.All patients underwent percutaneous balloon angioplasty via the cephalic vein.The success rate of technique, clinical success rate, perioperative complications and follow-up were observed.Results:(1) Technical success rate and clinical success rate 90 patients were treated with percutaneous transluminal angioplasty (PTA) via the cephalic vein, the other 3 patients were treated with interventional therapy via the brachial artery, and 3 patients underwent reconstruction of internal fistula.The technical success rate was 93.8% (90/96), and the clinical success rate was 89.6% (86/96). (2) Perioperative complications thrombosis in 4 cases, vasospasm in 3 cases.There were no serious complications such as vascular rupture, aneurysm, vascular dissection, and no perioperative death.(3) The first stage patency rate was 100% (90/90), 74.4% (67/90), 62.2% (56/90) and 46.7% (42/90) in 3, 6, 12 and 18 months after operation.Conclusion:Venipuncture can be used as the first choice for AVF stenosis interventional therapy because of its advantages of small trauma, no serious complications, no need of long-term compression at the puncture point, immediate dialysis, and avoidance of local hematoma and other complications caused by artery puncture.
