# Clinical Outcomes of Large-Bore Aspiration Thrombectomy for Tumor Pulmonary Embolism in Renal Cell Carcinoma

## TL;DR

A 66-year-old man with kidney cancer had a successful treatment for a tumor blockage in his lung, with no recurrence after four years.

## Contribution

Demonstrates long-term efficacy of large-bore aspiration thrombectomy in managing tumor pulmonary embolism.

## Key findings

- No disease recurrence was observed over four years following the procedure.
- The procedure provided both therapeutic and diagnostic benefits.
- Large-bore aspiration thrombectomy enabled histopathologic analysis for treatment guidance.

## Abstract

We present a 4-year longitudinal follow-up of a previously reported case involving a 66-year-old man with renal cell carcinoma who underwent radical nephrectomy, complicated by a massive pulmonary artery tumor embolism treated with large-bore aspiration thrombectomy. Serial clinical evaluations and imaging over 4 years have shown no evidence of disease recurrence following the initial intervention. This case underscores the evolving role of emergent large-bore aspiration thrombectomy in oncologic settings, not only as a therapeutic intervention but also for its diagnostic utility in enabling histopathologic characterization and guiding oncologic management.

Large-bore aspiration thrombectomy may offer long-term disease control in cases of tumor pulmonary embolism. This procedure can aid diagnosis and inform oncologic treatment planning through tissue acquisition.
