RESUMEN
A 68-year-old male with liver cirrhosis presented with dizziness and dyspnea two days after endoscopic Histoacryl occlusion of gastric varicses. Imaging revealed a large endovascular embolization of Histoacryl glue, spanning from porto-caval collaterals via the inferior vena cava to the right atrium, partially occluding right atrial inflow. This case report describes the successful removal of this large net-like mass of Histoacryl glue using thrombectomy devices from the inferior vena cava and the right atrium. Postprocedure imaging showed near-complete clearance with residual fragments in the superior mesenteric vein and small emboli in the pulmonary arteries. The patient was discharged in stable condition. Histoacryl glue can cause severe complications if embolized. This case highlights the potential of advanced thrombectomy devices for managing embolic complications from endovascular treatments.
RESUMEN
The management of metastatic hepatocellular carcinoma (HCC) is complex, particularly when complicated by pulmonary embolism. In these cases, atezolizumab-bevacizumab therapy is contraindicated due to an elevated risk of thromboembolic events. Differentiating pulmonary tumor embolism from thromboembolic disease is diagnostically challenging. This report outlines the benefit of transcatheter aspiration to obtain pathological evidence of pulmonary artery tumor embolus in an HCC patient. The intervention enabled a significant shift in the management strategy, leading to an escalation of systemic HCC therapy. This case underscores the importance of precise diagnostic techniques such as transcatheter aspiration in guiding treatment decisions, particularly in cases where pulmonary embolism may signify an underlying malignancy-driven process.
