Giant Subclavian Artery Aneurysm Associated with Airway Stenosis / 日本心臓血管外科学会雑誌

ABSTRACT

A 65-year-old man presented to our hospital with a chief complaint of hoarseness. Chest radiography and computed tomography detected a right subclavian artery aneurysm. The aneurysm had a maximum diameter of 85 mm, and was associated with a mural thrombus and displacement of the trachea to the left, which led to airway stenosis. In case ventilatory insufficiency developed during anesthesia induction, an extracorporeal membrane oxygenator was prepared, followed by administration of anesthesia. Careful administration of anesthesia allowed for anesthesia management without the extracorporeal membrane oxygenator. We approached the periphery and the proximal portion of the aneurysm through a right subclavicular incision and partial median sternotomy, respectively. After excision of the aneurysm, we performed EPTFE prosthesis implantation. The patient's postoperative course was uneventful, which led to postoperative improvement of the airway stenosis. The combination of a right subclavicular incision and partial median sternotomy is useful for the surgical treatment of large subclavian artery aneurysms such as the one in this case. Moreover, careful anesthesia management after close consultation with anesthesiologists is important for patients who exhibit preoperative airway stenosis.
