[Results of surgical treatment of chronic abdominal ischemia]

The immediate results of surgical treatment for chronic abdominal ischemia were studied in 112 patients. The late-term results were studied in follow-up periods of 6 months to 20 years in 105 (95.5%) patients treated by operation and in 45 patients who were not operated on. In the immediate postoperative period, positive results were recorded in 104 (92.8%), no changes were found in 4 (3.6%) patients, and fatal outcomes occurred in 4 cases (3.6%). In the late-term postoperative period the results were positive in 79 (75.2%) patients, no changes were produced in 3 (2.9%), the disease recurred in 21 (20%) patients, and 2 (1.9%) patients died. Actuarial analysis showed the late-term results of surgical treatment to be higher by 40.8% in a 5-year follow-up period and by 27.7% in a 10-year follow-up period (69.93 +/- 5.8% in a 5-year period and 36.69 +/- 9.43% in a 10-year period) than in nonoperative treatment (29.16 +/- 6.75% and 8.97 +/- 4.27%, respectively) in P less than 0.01.
