[Surgical treatment of abdominal aorta aneurysm 1983-1987. A multicenter study. 1266 operations, development and early results].

: During the years 1983-1987, 1,266 operations for abdominal aortic aneurysm (AAA) were carried out in eight surgical departments with vascular surgical function. The activity increased constantly corresponding to 311 patients in 1987 or 50% more than in 1983. During this period the distribution between patients subjected to elective operation and those operated upon as emergencies was very uniform. In the latter group, only a slight increase in the number of AAA patients with rupture was observed. The risk of complications was low with a significant decrease in the need for dialysis. The early mortality was constant for the patients subjected to elective operation remained constant about 5.5%. A marked decrease in the early mortality was observed for the patients operated upon as emergencies with rupture from 63 to 50% and without rupture from 37 to 25%. At the conclusion of the period, ultrasonic scanning became the preoperative investigation of election and introduction of an aortic prosthesis the method of operation of election. Patients with AAA should be recognized so that elective surgery can be offered before a condition endangering life develops.
