title: [Progress in surgery of the aortic arch].
abstract: We summarize our experience out of 133 operations involving the aortic arch which were performed in 130 patients throughout the last 13 years. Aortic pathology was aneurysmal disease in 57 cases, acute aortic dissection in 44, and chronic aortic dissection in 29 patients. Operative strategies included partial replacement or repair of the aortic arch in 80 cases and subtotal or total replacement of the transverse arch in 53 patients. In 19 cases presenting with aneurysms of the descending thoracic aorta, implantation of an elephant trunk prothesis was performed simultaneously. The operations were performed during circulatory arrest (10-64 min, mean: 27 min) and in deep hypothermia (nasopharyngeal temperature: 11-25 degrees C). Recently, two modifications of the technique were introduced: First, the site of arterial inflow cannulation is changed by intubating the prothesis directly during reperfusion providing antegrade perfusion. Second, in patients with acute aortic dissection, the false lumen of the aortic root and arch is filled with resorcinformol glue and the layers are readapted by this means after anatomical reconstruction. Overall, early mortality was 14.3% and was much higher in acute dissection (22.7%) when compared to chronic dissection (6.9%, p = 0.110). A total of 24 reoperations were necessary in 16 patients of this group with subsequent replacement of the descending thoracic aorta being most frequently performed (n = 14). Actuarial survival after 5 years was not significantly different between the groups (69.1%) but showed a progressive decline for patients with aneurysms and chronic dissection (11 late deaths) while no late deaths occurred in acute dissections.(ABSTRACT TRUNCATED AT 250 WORDS)
