“…23,24 Recent studies have proven that CT venography (CTV) is efficient for evaluating venous anatomic abnormalities including stenosis or thrombosis. 25 Although, contrast, cost, and availability are major considerations of CTV, this examination has advantages in selected patients. In particular, we observed that 70.3% of patients with IVC thrombosis suffered from obvious back pain in this study.…”

Purpose To evaluate the safety, feasibility and technical aspects of endovascular treatments for inferior vena cava (IVC) thrombosis secondary to deep venous thrombosis of the lower extremities. Materials and Methods A retrospective study of patients from two centres who received endovascular treatment for IVC thrombosis from January 2015 to December 2020. Under the protection of the IVC filter, all lesions were treated with manual aspiration thrombectomy (MAT) followed by catheter-directed thrombolysis (CDT). Technical aspects, complications, IVC patency, Venous Clinical Severity Score (VCSS) score and Villalta score were recorded during the follow-up observation. Results Endovascular procedures including MAT and CDT were performed successfully in 36 patients (97.3%). The average duration of the endovascular procedure was 71 minutes (range: 35-152 min). To protect against fatal pulmonary artery embolism, 33 filters (91.7%) were deployed in the inferior renal IVC, while three patients (8.3%) received filter implantation in the retrohepatic IVC. No severe complications occurred during the procedure. In the follow-up observations, the cumulative primary and secondary patency rates in IVC were 95% and 100%, respectively. The patency rates for the iliac vein were as follows: a primary patency rate of 77% and a secondary patency rate of 85%. The average VCSS score was 5.9 ± 2.6, and the Villalta score was 3.9 ± 2.2. The rate of post thrombotic syndrome is 22% in our study as assessed by the villalta score (Villalta score>4). Conclusions Endovascular treatment for IVC thrombosis secondary to DVT of the lower extremities is feasible, safe, and effective. This strategy alleviates venous insufficiency and results in a high patency rate in IVC.
