Abstract
Ascending aorta-infrarenal abdominal aorta bypass was performed in 8 patients: 4 patients with dissecting aortic aneurysm, 3 patients with thoracic aneurysm and 1 patient with stenosis of the thoracic aorta after grafting for congenital thoracic aneurysm. Four patients who had aortic dissection underwent the thromboexclusion method, but thromboexclusion of the thoracic aorta occured in only one patient after additional clamp to the distal thoracic aorta. He is the only long-term survival in this series. The thromboexclusion method was also performed in two patients with infectious thoracic aortic aneurysm, but they died of aneurysmal rupture within 13 months after operation. One patient who undewent resection of a thoracic aneurysm with extra-anatomic bypass, developed respiratory insufficiency and paraplegia, and died of pneumonia. The patient with thoracic aortic stenosis is alive and well 11 years after operation. The indications of the thromboexclusion method for thoracic aneurysm should be limited only to very poor-risk patients who seem to be inaccessible to a direct approach. Ascending aorta-abdominal aorta bypass is recommended in cases of thoracic aortic stenosis.
