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

## TL;DR

This paper reports the first case in North Brazil of a minimally invasive procedure to remove a large blood clot in a leg vein, resulting in a successful recovery.

## Contribution

The paper presents the first documented use of percutaneous mechanical thrombectomy for extensive DVT in the northern region of Brazil.

## Key findings

- Percutaneous mechanical thrombectomy was safely and effectively used to treat a patient with extensive deep vein thrombosis.
- The patient experienced rapid clinical recovery and remained asymptomatic at 14 months of follow-up.
- The procedure is highlighted as a feasible and innovative treatment option in regional medical settings.

## Abstract

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.

Relata-se o primeiro caso documentado na região Norte do Brasil de trombectomia mecânica percutânea (TMP) em paciente jovem com trombose venosa profunda (TVP) ilíaco-fêmoro-poplítea. O paciente apresentava dor e edema significativo no membro inferior esquerdo, com evidência ecográfica de TVP extensa. Optou-se pelo uso do sistema ClotTriever®, com acesso poplíteo e técnica associada de embolectomia com cateter Fogarty. O procedimento transcorreu sem intercorrências e resultou em rápida recuperação clínica. Após 14 meses de seguimento, o paciente encontrava-se assintomático, com eco-Doppler venoso normal. A TMP mostrou-se segura, eficaz e viável como opção terapêutica inovadora em contexto regional. Este relato reforça o papel da técnica como alternativa promissora para o tratamento de TVPs extensas, especialmente em centros fora de grandes áreas urbanas.
