“…21 Interestingly, some surgeons took advantage of specific thrombectomy devices (FlowTriever and ClotTriever systems) to remove clot burden without the use of thrombolytic drugs. 8 However, until now, the literature on endovascular treatment for DVT extending to IVC has been sparse, consisting of a small number of patients. There was substantial and significant heterogeneity between studies.…”

“…Compared with patients with DVT, the risk of thrombosis-related mortality is relatively high. [7][8][9][10] However, to our knowledge, few studies have focused on endovascular treatment for patients with IVC thrombosis secondary to DVT. Our study seeks to retrospectively evaluate the feasibility and effectiveness of endovascular treatment for IVC thrombosis in two centres.…”

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.

“…Typically, these systems are reserved for retrieval of pulmonary embolisms after the Favipiravir +/- Lopinavir: A RCT of Early Antivirals (FLARE) trial demonstrated safe and efficacious intervention [ 7 ]. However, these systems can rarely be utilized for other large vessels and have been effective in complex DVT interventions [ 10 , 11 ]. Specifically, in this patient, the FlowTriever system retrieved a significant amount of thrombus without complications.…”

A deep vein thrombosis (DVT) is a multifactorial condition characterized by a thrombus or blood clot developing in the deep veins of the upper or lower extremities. The presentation of DVT is characterized by unilateral peripheral edema and signs of inflammation in the affected extremity. The treatment of DVT is complex and case-dependent; however, most individuals are managed with oral anticoagulation therapy, while complex cases can be treated with advanced interventions. This report discusses a singular case of an atypical or complex DVT in a middle-aged woman with prior venous thromboembolic events undergoing a thrombectomy using an Inari FlowTriever system.

“…Three small series have evaluated the ClotTriever device (Inari Medical, Irvine, Calif) and demonstrated efficient acute and older thrombus removal without bleeding complications, with the clinical relief recorded for all the patients. 32,35,36 Only early follow-up data were reported, and a 20% rate of recurrence was recorded.…”
