Robotic right lower lobectomy for a persistent large pulmonary arteriovenous malformation following repeated coil embolization

Abstract

Pulmonary arteriovenous malformations create continuous shunting of unoxygenated blood through the lungs into the systemic circulation. These malformations are asymptomatic if small, but cause serious symptoms as they grow in size. Treatment primarily consists of endovascular embolization; lobectomy is preserved for recurring or endovascularly untreatable cases. We describe a case of a 24-year-old man who was first treated with coil embolization 10 years previously, with complete symptom resolution. However, more recently he noted recurrent exercise intolerance, with shortness of breath and hypoxemia. After repeat re-embolization, a computed tomography scan noted some persistent flow. Given the patient's young age, we considered resection as a definite therapy. The patient underwent an uncomplicated robot-assisted right lower lobectomy. Afterward, his symptoms resolved completely. In selected cases, robotic lobectomy for pulmonary arteriovenous malformation is feasible and safe.
