Objective: This study aimed to evaluate the results of endovascular management of the central venous stenosis or obstruction (CVD) in hemodialysis (HD) patients via ipsilateral arteriovenous fistula (AVF). Methods: Retrospective method with HD patients treated CVD by interventional therapy using balloon or stent, at Vascular Surgery department of Cho Ray hospital from January 2017 to December 2019. Results: There were 32 cases of central venoplasty with local anesthesia via ipsilateral AVF. The average age was 55,6 ± 3,2, the male/female ratio was 1,67/1. Interventional indications were arm swelling (100%), pain in the arm (75%), skin dystrophy (50%), dilated veins in the ipsilateral neck and face (50%). 62,5% of them had a history of catheterization which was ipsilateral to lession. Each procedure had the average time 66,3 ± 6,2 minutes. Stent placement was followed after ineffective baloon angioplasty in 6 cases. The technique success rate was 87,5%. * Bệnh viện Chợ Rẫy Người chịu trách nhiệm khoa học: PGS.TS Trần Quyết Tiến Ngày nhận bài: 28/12/2020 Ngày Cho Phép Đăng: 22/01/2021 PHẪU THUẬT TIM MẠCH VÀ LỒNG NGỰC VIỆT NAM SỐ 31 THÁNG 1/2021 28 There was no major complication and death perioperatively. The symptoms of venous hypertension were resolved after intervention in all cases. The postoperative average time in the hospital was around 2,5 ± 0,8 days. After 6 months, there were 10 cases (31,3%) required to re-endovascular treatment. Conclusions: The endovascular intervention is a safe and effective method for CVD because of good rate of technical success, low rate of complications, reducing the duration of procedure and discharge. However, the disease has a high recurrence rate. Enhanced follow-up and repeated interventions are required to maintain the patency for long term.
