Abstract:
OBJECTIVE:To evaluate the long-term efficacy of percutaneous mechanical thrombectomy (PMT) combined with stent implantation in treatment of acute iliofemoral vein thrombosis.
METHODS:Seventy patients with acute iliac vein thrombosis were treated with PMT combined stent implantation in Ningbo No.2 Hospital from November 2015 to November 2017. During the follow-up, the improvement of blood flow was evaluated, the occurrence of post-thrombotic syndrome was assessed by the Villalta rating scale, and the stent patency was examined with lower extremity ultrasound or angiography.
RESULTS:The blood flow was significantly improved after procedure in all 70 patients, including 62 cases (88.6%) of grade Ⅲ clearance, 5 cases (7.1%) of grade Ⅱ clearance, and 3 cases (4.3%) of grade Ⅰ clearance. No significant complications occurred during the treatment. The patients were followed up for (15.0±2.5) months. During the follow-up, 64 patients (91.4%) had unobstructed stents, and 9 patients (12.8%) had post-thrombotic syndrome.
CONCLUSIONS:PMT combined with stent implantation is effective in the treatment of acute iliac vein thrombosis with a high medium-and long-term stent patency rate.
