RESUMEN
Objective:To compare the clinical effect and perioperative complications of the treatment of autogenous arteriovenous fistula stenosis by arterial and venous approach.Methods:The clinical data of 120 patients with AVF stenosis and occlusion who were treated with interventional therapy and met the inclusion criteria were collected and analyzed by retrospective case-control study.from September 2017 to August 2018, 60 patients with internal fistula stenosis were treated by transarterial approach (arterial approach group), and from September 2018 to may 2019, 60 patients were treated with a new surgical scheme(venous approach group). The operation success rate, perioperative complications and patency rate of 3, 6, 12 months after operation were compared between the two groups.Results:(1) The technical success rate was 96.7% (58/60) and the clinical success rate was 91.7% (55/60) in the arterial approach group, and 95.0%(57/60) and 93.3%(56/60) in the venous approach group.There was no significant difference in the technical success rate and clinical success rate between the two groups ( P=0.718 and 1.000, respectively) (2) Perioperative complications: in the arterial approach group, 3 patients had hematoma at the puncture point, 2 pseudoaneurysms and 5 thrombosis.There were 3 patients with thrombosis in the venous access group, and the difference in the incidence of complications between the two groups was statistically significant (χ 2=4.227, P=0.036). (3)The primary patency rates at 3, 6 and 12 months after operation were 95.0%(57/60), 75.0%(45/60) and 60.0%(36/60) in the arterial approach group, and 96.7%(58/60), 71.7%(43/60) and 61.7%(37/60) in the venous access group, respectively.There was no statistically significant difference between the two groups ( P=0.718, 0.749, 0.885). Conclusion:The interventional treatment for autogenous arteriovenous fistula stenosis through artery and vein approach can achieve good effect.There were many complications during the perioperative period, It is suggested that venous approach is preferred.
RESUMEN
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.
