Abstract
Objective:To observe the efficacy of percutaneous transluminal balloon angioplasty (PTA) and percutaneous transluminal stenting (PTS) in the treatment of central venous stenosis in hemodialysis patients.
Methods:A total of 40 hemodialysis patients with central venous stenosis were admitted during the period from October 2014 to October 2016. According to the type of treatment, the patients were divided into PTA treatment group (n=26) and PTA+PTS treatment group (n=14) . The changes of the curative effect and the path of the two groups were observed, and the opening information and opening time of the 1, 3 and 6 months were followed up.
Results:The related symptoms were improved within 1 week after operation, and the diameter of the access was wider after operation. The primary patency time with PTA group [ (5.17±1.54) months] was significantly higher than that with PTA+PTS group [ (3.57±1.71) months]; The number of intraluminal interventions in PTA+PTS group [ (1.93±0.47) times] was higher than that in PTA group [ (1.35±0.56) times], and the differences were statistically significant. The primary patency rates with PTA in 1, 3 and 6 months were 96.2%, 80.7% and 69.2%, respectively, and the assisted primary patency rates were 100%, 92.3% and 92.3%. The primary patency rates with PTA+PTS in 1, 3 and 6 months were 92.9%, 64.3% and 14.3% respectively, and the assisted primary patency rates were 100%, 100% and 85.7%. There was no significant difference between the two groups in primary patency rates and assisted primary patency rates.
Conclusions:PTA is preferred in the treatment of central venous stenosis in hemodialysis patients. When PTA resistance or frequent relapse happened, stent placement should be considered.
