Key result
Large-bore aspiration thrombectomy successfully recanalizes pulmonary tumor embolism and yields histological diagnosis in a case.
Why the study?
Pulmonary tumor embolism is a rare, life-threatening condition with unpredictable clinical course and high mortality, posing management challenges despite advancements.
Does large-bore mechanical aspiration thrombectomy improve clinical status and recanalization in a patient with intermediate-risk pulmonary tumor embolism refractory to anticoagulation?

Large-bore mechanical aspiration thrombectomy can successfully restore pulmonary perfusion, rapidly improve clinical symptoms, and provide diagnostic tissue for histopathological confirmation in patients with intermediate-risk pulmonary tumor embolism.
Pulmonary tumor embolism (PTE) is a rare but potentially life-threatening form of non-thrombotic pulmonary embolism.Despite advancements in management, it remains a challenging entity due to its unpredictable clinical course and high mortality rate.With the advent of minimally invasive endovascular treatment modalities, the management of pulmonary embolism has witnessed a shift from systemic thrombolysis or surgical thromboarterectomy to catheter-directed thrombolysis, mechanical thrombectomy, or pharmaco-mechanical thrombectomy, combining mechanical thrombectomy with catheter-directed thrombolysis.We report a rare case of intermediate-risk pulmonary tumor embolism managed by large-bore aspiration thrombectomy.

Bhardwaj et al. (2026) conducted a case report in Intermediate-risk pulmonary tumor embolism secondary to colon adenocarcinoma (n=1). Large-bore computer-assisted vacuum aspiration thrombectomy (Indigo System CAT 16 catheter) was evaluated on Technical and clinical success (recanalization of left pulmonary artery, improvement in vital parameters and dyspnea, and histopathological diagnosis). Large-bore aspiration thrombectomy achieved successful recanalization, symptom resolution over 6 months, and histological confirmation of metastatic adenocarcinoma in a 65-year-old woman with PTE.
