Abstract:

Objectives: In this study, we report our mid- and long-term results of extra-anatomic bypass surgery. Patients and methods: Between January 2005 and December 2011, a total of 65 patients (54 males, 11 females; mean age: 54.3±4.2 years; range, 20 to 82 years) with extra-anatomic bypass surgery with complete follow-up data were retrospectively analyzed. Extra-anatomic bypass surgery was performed to the lower extremity in 36 (55.3%) and the upper extremity in 29 (44.7%) patients. Additional distal bypass surgery was done in 18 of 36 patients with lower extremity disease. Results: The median follow-up time was 3.6 years (range, 3 months to 6 years). There was no early mortality, while there were five reoperations due to graft thrombosis and two amputations due to insufficient arterial flow in the postoperative period. There were two reoperations due to graft thrombosis and graft infection as late morbidity. In the long-term, the mortality rate was 6% (n=4) related to the malignancy in two patients, pulmonary embolism in one patient, and aortoduodenal fistula in one patient. Conclusion: An extra-anatomic bypass procedure is a surgical approach that can still be performed with low mortality and morbidity rates and acceptable patency rates in high-risk patients.
