We report an 85-year-old woman with rupture of aneurysm of the descending thoracic aorta into the left lung. She was admitted with sudden onset back pain and hemoptysis. Emergency operation was performed to replace the ruptured descending thoracic aorta, and lower lobectomy of left lung. The left lobectomy ensured that hematoma was not left in lung, although it decreased respiratory function after operation. In addition, it decreased bleeding and operating time compared to segmental resection. She was discharged without contracting an infection in the lung or graft, although she needed tracheotomy for a time. We suggest that the lower lobectomy of lung was an important factor in saving this elderly patient with rupture of an aneurysm into the left lung.

A 71-year-old man was referred to the University Hospital because of left lumbago and a pulsating mass in his umbilical region. An inflammatory abdominal aortic aneurysm 5cm in diameter and left hydronephrosis were identified by enhanced computed tomography (CT). One month after admission, rapid expansion of the aneurysm with sealed rupture were detected by follow-up enhanced CT. The patient immediately underwent an emergency operation. We confirmed fissure on the posterior aneurysmal wall with a localized hematoma. We replaced the aneurysm with a straight prosthetic graft and the postoperative course was uneventful.

Between January 1980 and September 1993, 7(8.4%) of 83 patients with aortic dissection had coincident atherosclerotic true aneurysms of thoracic and/or abdominal aorta or had undergone operation of true aortic aneurysms. There was no difference in the segments of aortic dissection; 4 of 50 patinets classified as DeBakey III and 3 of 33 patients classified as DeBakey I or II, whereas the site of atherosclerotic true aneurysms was more often in the abdominal aorta than in the thoracic aorta. Five patients had undergone surgery for or had the abdominal aortic aneurysms and 2 patients had thoracic aortic aneurysms. In 2 patients who had previously undergone abdominal aortic aneurysmectomy, the dissected aorta ruptured soon after the onset of dissection. In the patients in whom the true aneurysm and the aortic dissection involve the same segments surgical treatment would be extended and complex.

A 64-year-old man with a history of anterior blunt trauma 10 years previously was admitted to our hospital complaining of general fatigue. A plain chest roentgenogram showed pericardial calcification. Computed tomography and echocardiography showed the mass to be a calcified capsule in the anterior mediastinum compressing the right side of the heart. He underwent an operation through a median sternotomy. The mass was an organized hematoma encapsulated by a calcified fibrous and serous layer of the pericardium. The hematoma was resected together with the calcified pericardium under cardiopulmonary bypass. His postoperative course was uneventful. He had no history of hemopericardium but had experienced blunt chest trauma that seemed to have induced the subsequent localized constrictive pericarditis.

We report a case of aneurysm localized to the noncoronary sinus of Valsalva with moderate aortic regurgitation (AR). The patient was a 49-year-old woman who had been suspected to have some kind of connective tissue disorders. She underwent an aortic root remodeling procedure to replace the isolated, unruptured and extracardiac aneurysm and the ascending aorta. Postoperative angiogram showed no aneurysm and improved AR. This procedure was able to preserve her own aortic valve and normal sinuses of Valsalva and enable her to obtain better quality of life, although progression of the enlargement of the aorta or AR requires careful follow-up.
