[Surgical management for acute aortic dissection with organ ischemia].
In a series of one hundred and one cases of surgical treatment for acute aortic dissection between January 1986 and September 1997, we evaluated 29 cases presenting with organ ischemia. These consisted of 23 cases of acute type A dissection (type A) and 6 cases of type B dissection (type B). Organ ischemia was diagnosed by (1) aortography, (2) a retrospective review of the history and (3) physical examination or laboratory data. The 23 surgical cases of acute type A dissection consisted of, coronary ischemia 8 cases, cerebral and spinal cord ischemia 9 cases, intestinal ischemia 3 cases, lower extremities ischemia 10 cases, and plural organs ischemia 8 cases. In the 6 cases of acute type B, we noted 4 intestinal ischemias and 2 lower extremities ischemias. The operative mortality rates when subdivided according to ischemic organ were: coronary ischemia 50%, cerebral and spinal cord ischemia 11%, intestinal ischemia type A 33%, type B 50%, and lower extremities ischemia type A 33%, type B 0%. The operative mortality rates, especially for patients presenting with acute myocardial infarction or intestinal ischemia, were relatively high. In cases of acute aortic dissection when organ ischemia occurred, we believed that it was necessary to perform early thoracic aortic repair and reconstruction of the ischemic organ.
