Saccular descending thoracic aortic aneurysm with dysphagia.

A 76 year old woman had suffered from chest pain, back pain, and dysphagia for 8 months. She was diagnosed as having a thoracic aortic aneurysm by chest X-ray and chest enhanced computed tomography. Simultaneously, severe dysphagia developed. Chest enhanced computed tomography and chest aortic aortography at our hospital demonstrated a saccular descending thoracic aortic aneurysm. Esophagography demonstrated that the esophagus was compressed by the aneurysm; therefore, a graft replacement for the saccular descending thoracic aortic aneurysm was performed on Feburary 17th, 1998. A left sided 6th intercostal approach was made, and graft replacement for the aneurysm using a 22 mm Hemashield prosthetic graft was performed under temporary bypass from the thoracic aorta just distal to the left subclavian artery and to the left femoral artery. The postoperative course was uneventful, the severe dysphagia improved dramatically, but a pleural effusion of 1000 ml collected 3 weeks after the operation. Surgical cases of saccular descending thoracic aortic aneurysm with dysphagia are rare, and with this in mind, we report this case to the the medical literature.
