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.

Clinical training programs play an extremely important role in the new postgraduate clinical training system introduced in 2004 because facilities for clinical training now include various health-related institutions in addition to the university hospitals and special hospitals for clinical training used in the previous system. Although educational goals have been established by the Ministry of Health, Labour and Welfare, trainees may have difficulty achieving these goals, even under the guidance of staff at the various facilities. There are differences in the function and quality of health-related institutions in the community. For the practical and convenient application of educational goals, we have attempted develop a “model program” to supplement the objectives indicated by the learning goals with more specific objectives. These supplementary objectives can be modified by individual institutions. We hope that this “model program” contributes to the development of objectives for each institution and helps improve the quality of the postgraduate training system in Japan.
