Abdominal revascularization patency outcomes of thoracoabdominal aortic aneurysm and mesenteric ischaemia

Abstract

Aim: Thoracoabdominal aortic aneurysm (TAAA) and Mesenteric ischemia (MI) are multifactorial and hereditary diseases which also have associations with systemic atherosclerosis and genetic factors. As it is known, mortality and morbidity rates are very high for open surgery; therefore, hybrid approach, with better outcomes, has become more popular as a new alternative treatment option for TAAA patients. The aim of the study was to compare the graft patencies of all patients who underwent visceral revascularization with different aetiology. Material and Methods: 34 patients who underwent visceral revascularization, either for MI (n:16) or TAAA hybrid procedure(n:18) were included in this study. All data was collected retrospectively and was analysed with SPSS 21.0 software program. Chi-square and Fischer tests were used in the analysis of qualitative data; and results with a p value below 0.05 were considered as statistically significant. Results: There was no significant difference between two patient groups in terms of graft patency rates. All type 2 endoleaks were resolved spontaneously in control CT angiography and no migration was observed in patients. Conclusion: In line with the results obtained, it has been revealed that visceral revascularization surgery can be used not only for the final treatment of MI, but also as a step in the hybrid approaches of TAA.
