A 54 year old female with bilateral traumatic pulmonary cyst due to agricultural accident is reported.
She was run over by a tractor and admitted to our hospital in forty minutes after injury.
Her X-ray film on 7 th day revealed bilateral pulmonary cyst and intrapulmonary hematoma.
But, these abnormal shadows disappeared completely on 70 the day after injury.
We consider that operative treatment for the traumatic lung cyst or intrapulmenary hematoma is not need unless we can find the conditions that give a positive support to thoracotomy.

We report 18 cases of thoracoabdominal aortic aneurysm repair. Most causes of the thoracoabdominal aortic aneurysm were atherosclerotic lesions (56%) or inflammatory changes (39%), such as Takayasu's aortitis and Behçet's disease. The Crawford procedure was performed in 13 patients, patch aortoplasty in 3, the Hardy procedure in 1 and extra-anatomic bypass in 1. As an adjunct, temporary bypass was employed in 8 patients and F-F bypass in 7 patients. Visceral arteries were perfused selectively during aortic cross-clamp. A total of 39% of all patients required emergency surgery for rupture, and among inflammatory aneurysms 86% of them ruptured. The early mortality rate was 0% in non-ruptured thoracoabdominal aneurysms, 42.9% in ruptured and 16.7% overall. There were 3 severe post-operative complications including one each of paraplegia, non-occlusive intestinal ischemia and rupture. All of them turned resulted in in-hospital death and the in-hospital mortality rate was 33.3%. There was no late death among atherosclerotic thoracoabdominal aortic aneurysms. However both Behçet's disease cases required re-operation for rupture at the anastomotic site in the late postoperative period and one patient died. One Marfan's syndrome patient also died 3 years postoperatively. We conclude that the Crawford procedure with F-F bypass is an effective and safe approach to thoracoabdominal aortic aneurysm repair and yields good clinical results.

Nine patients with type IIIb dissecting aortic aneurysm underwent graft replacement of the thoracic and abdominal aorta between 1988 and 1992. The spiral opening method was used to expose the thoracic and abdominal aorta. Temporal bypass was employed in 2 patients and F-F bypass in 7 patients. Visceral arteries were perfused selectively during aortic cross-clamp. The entire descending thoracic aorta and abdominal aorta was reconstructed in 6 patients and the proximal descending thoracic aorta to renal arteries in 3 patients. The Crawford graft inclusion technique was used in all cases. Three patients required emergency surgery for rupture in one and impending rupture in 2. Operative deaths occurred in 2 patients (22.2%). Morbidity included renal failure (2), bleeding requiring reoperation (2), arrythmia (1), paraplegia (1), paraparesis (1), respiratory failure (1) and ileus (1). In the past two years, we operated on 5 cases of type IIIb dissecting aneurysms and there was neither operative death nor paraplegia.
