The efficacy of endovascular stent in the treatment of iliofemoral post-thrombosis syndrome

ObjectiveTo investigate the clinical effects of endovascular stent in the treatment of iliofemoral post-thrombosis syndrome(PTS).

MethodsThe clinical data of 27 patients with iliofemoral PTS were analyzed retrospectively.After venous recanaliztion and self-expandable stenting, the patients were followed up for 6 months.The severity of PTS and quality of life before and after treatment were evaluated using Villalta score and chronic venous insufficiency questionnaire(CIVIQ-20) scale.

ResultsAll patients were successfully recanalized after operation.After 6 months fo following-up, the primary patency rate, assisted patency rate and secondary patency rate were 66.7%(18/27), 77.8%(21/27) and 88.9%(24/27), respectively.The Villalta score decreased from(17.44±5.49) before operation to(5.78±3.31) after operation(P<0.01), while the CIVIQ-20 scores increased from(37.26±10.89) to(58.93±12.91)(P<0.01).The severity of postoperative half-year follow-up was significantly lower than that before surgery(P<0.01).The results of logistic regression analysis showed that the preoperative Villalta and CIVIQ-20 scores, and age were the independent factors related to the Villalta gain, and the preoperative Villalta was the independent factors related to the CIVIQ-20 gain.

ConclusionsThe endovascular stent in the treatment of iliofemoral PTS is effective, which can reduce the severity of PTS and improve the quality of life.
