Abstract
An 11-year-old girl was referred to interventional radiology with a suspected pulmonary embolism (PE) 10 days post-resection of a benign craniopharyngioma. Acute massive PE was confirmed through computed tomography (CT) with extensive thrombus burden and CT evidence of high-grade right ventricular strain. Due to profound hypoxemia and hemodynamic instability, the patient was placed on extracorporeal membrane oxygenation and emergency percutaneous mechanical thrombectomy through the FlowTriever® System (Inari Medical, Irvine, CA) was pursued. A large volume of thrombus was extracted through aspiration without the need for thrombolytics. Postprocedure pulmonary angiography confirmed complete restoration of blood flow to both lungs and resolution of pulmonary symptoms continues 9 months after the procedure.
