Abstract

This article presents a 33-year-old male with systemic lupus erythematosus and acute extensive thrombosis of both renal veins, inferior vena cava, and iliac veins, leading to renal failure. Catheter-based thrombectomy (EKOS system) achieved complete thrombus removal, with full renal function recovery. This case validates the efficacy of mechanical thrombectomy in acute renal vein thrombosis.

Introduction

Acute renal vein thrombosis may cause irreversible kidney injury. Catheter-directed thrombectomy (CDT) offers a novel approach for rapid revascularization.

Case Study

•The patient presented with leg swelling, purple discoloration, and acute renal failure. Imaging confirmed extensive thrombosis. Initial EKOS-assisted thrombolysis was followed by re-do mechanical thrombectomy (AngioJet™). 

•Post-procedural creatinine decreased from 4.2 mg/dL to 1.1 mg/dL. Follow-up showed stable renal function without recurrence.

Conclusions

1.Mechanical thrombectomy rapidly restores renal perfusion and preserves function.

2.Combined immunomodulatory and anticoagulant therapy is essential for long-term management.

3.Early intervention prevents chronic kidney injury.
