We report 3 cases of rare lesions of the lateral thoracic artery (LTA) treated with endovascular or surgical treatment. Case 1: A 31-year-old man with Marfan syndrome. He had undergone Bentall surgery for type A acute aortic dissection with annuloaortic ectasis 6 years ago and had been anticoagulated with warfarin since then. He presented to the emergency department with a complaint of bloody sputum, and a close examination revealed an intrathoracic hematoma due to spontaneous rupture of the right LTA. The patient underwent effective hemostasis by embolization of the responsible artery. Case 2: 69-year-old man presented to his local doctor with a complaint of increasing left back pain, and a pulsatile mass with thrill was palpated at the same location as the pain. CT scan revealed a pseudoaneurysm associated with a left lateral thoracic arteriovenous malformation. Endovascular treatment was performed by embolization of a pseudoaneurysm to achieve disappearance of blood flow. Case 3: A 37-year-old man with a history of surgery for left spontaneous pneumothorax. He presented hospital with hemoptysis and repeated bloody sputum and was diagnosed a left LTA-pulmonary artery fistula and hemorrhage from the same site. Thoracoscopic dissection of the neovascularization and partial resection of the lingular segment of the left lung were performed.
