Surgical Treatment of a Posttraumatic Pseudoaneurysm of the Left Subclavian Artery Mimicking a Mediastinal Tumor: A case report / 대한흉부외과학회지

ABSTRACT

Posttraumatic pseudoaneurysms of the subclavian artery are very rare. A 49-year-old woman who had been involved in a car accident ten years before presentation was initially diagnosed with a mediastinal tumor at a local clinic. Exploratory thoracotomy was performed for evaluation and treatment. During the operation, a hematoma was evacuated, and primary repair was undertaken to stop massive bleeding. Computed tomography angiography revealed a pseudoaneurysm of the left subclavian artery. The patient was treated with aneurysmectomy and end-to-end anastomosis. The postoperative course was uneventful.
