Percutaneous mechanical thrombectomy in a patient with extensive deep vein thrombosis: pioneering surgery in the northern region

This report presents the first documented case in North Brazil of percutaneous mechanical thrombectomy (PMT) performed in a young patient with extensive iliofemoral-popliteal deep vein thrombosis (DVT). The patient presented with pain and significant swelling of the left lower limb, with ultrasonographic evidence of extensive DVT. The ClotTriever® system was employed via a popliteal approach, combined with adjunctive embolectomy using a Fogarty catheter. The procedure was uneventful and led to rapid clinical recovery. At 14 months of follow-up, the patient was asymptomatic, and venous Doppler ultrasonography findings were normal. PMT proved to be safe, effective, and feasible as an innovative therapeutic option in a regional setting. This case underscores the technique’s potential role as a promising alternative for treatment of extensive DVT, particularly in centers outside major urban areas.
