Abstract 11104: Percutaneous Embolization of Extensive Collateral Vessels for Hemoptysis in Pulmonary Aspergilloma

Introduction: Pulmonary aspergillomas form due to fungal colonization in patients with immunocompromise and underlying cavitary lung disease. They can present with hemoptysis due to erosion of pulmonary vessels and formation of collaterals. Arterial embolization of bronchial vessels is considered first line treatment due to effectiveness and minimal invasiveness. We present one patient with need for extensive embolization treatment for persistent hemoptysis. Case: 53yo woman with pulmonary sarcoidosis and bilateral pulmonary aspergilloma presented to our institution for lung transplant evaluation. She had persistent hemoptysis for years after being diagnosed. She previously had bronchial artery embolization at outside hospital but had persistent symptoms severely limiting her functional status. She continued to have active hemoptysis during the admission, including on arrival to procedure. Angiography demonstrated extensive collateral vessels from systemic arterial to pulmonary circulation including several large branches originating from the subclavian arteries, internal mammary arteries and dorsal scapular arteries. There was leak through multiple previously embolized arteries, with active extravasation of contrast. Initial large collaterals were embolized using Medtronic MVP micro-vascular plugs (3Q, 5Q, 7Q) and smaller collaterals from intercostal arteries embolized using Penumbra Ruby Coil. She had improvement following the first procedure, but had persistent hemoptysis requiring repeat procedures to address more collateral and native vessels prior to resolution of symptoms. Conclusions: This patient with bilateral pulmonary aspergilloma had previous unsuccessful coil embolizations and complex collateral vessel system that resulted in severe recurrent bleeds. We successfully treated this patient’s persistent massive hemoptysis after extensive embolizations during multiple challenging procedures.
