Between January 1991 and February 1993, 14 @entity1 (3 female, 11 male) aged between 21 and 79 years (mean 50 years) underwent reconstruction of the thoracic (n = 7) and thoracoabdominal aorta (n = 7). Four @entity1 had previously undergone operation of the ascending aorta, in 3 @entity1 coronary artery by pass grafting was performed before. All @entity1 were operated using cardiopulmonary bypass with continuous blood cardioplegia, hypothermic @entity1167 (11 degrees C nasopharyngeal temperature, 0-EEG) and posterolateral exposure. All patent lower intercostal and lumbar arteries (Th3-L5) were reimplanted. The 30-day mortality after repair of the thoracic aorta was 0, after replacement of the thoracoabdominal aorta 28.5% (n = 2). One @entity1 died 70 days after replacement of the thoracic aorta as a consequence of a perioperative @entity64 . None of the surviving 11 @entity1 developed a permanent @entity51 , @entity299 . The average intensive care stay was 6 days for @entity1 after replacement of the thoracic and 18 days for @entity1 after replacement of the thoracoabdominal aorta. Our results indicate the method of elective @entity2332 and @entity1167 effective in spinal cord protection. The increase in the tolerable duration of @entity2759 supports the reimplantation of all intercostal and lumbar vessels.
