Percutaneous Thrombectomy Using a Computer-Assisted Aspiration Device for Deep Vein Thrombosis

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Device Technology

Background:

• Deep vein thrombosis (DVT) poses significant risks, including pulmonary embolism and post-thrombotic syndrome.
• Traditional DVT treatments may have limitations, necessitating advanced minimally invasive options.

Purpose of the Study:

• To evaluate the safety and efficacy of a computer-assisted large-bore thrombectomy (CA-LBT) device.
• To assess CA-LBT in aspiration thrombectomy for treating deep vein thrombosis (DVT).

Main Methods:

• Retrospective review of 16 consecutive DVT patients treated with a 16-F CA-LBT device.
• Analysis of patient demographics, DVT locations (iliofemoral, axillosubclavian, caval), and procedural details.
• Inclusion of fluoroscopy time, contrast volume, and adjunctive procedures like venoplasty and stenting.

Main Results:

• 100% restoration of anterograde flow was achieved in all treated DVT cases.
• 86.7% of patients experienced symptom improvement, with 85.7% confirmed patency on follow-up imaging.
• The CA-LBT device facilitated treatment across various venous access sites, including popliteal, femoral, and brachial veins.

Conclusions:

• Aspiration thrombectomy using the 16-F CA-LBT device is a feasible and effective treatment for proximal and large-volume DVT.
• The technology shows promise in improving patient outcomes and managing complex DVT cases.
• Further research may explore long-term outcomes and comparisons with other thrombectomy methods.
