Abstract
Background
In this study, surgical tactic features and juxtarenal and pararenal treatment immediate results were analyzed depending on the use of various surgical approaches.
Methods
Between 2015 and 2019, a total of 89 patients received surgical treatment, of which 52(58%) had juxtarenal aneurysms and 37 (42%) – pararenal aneurysms. During repairs, three types of surgical approaches were used: midline laparotomy, extended retroperitoneal approach and thoraco-phreno-retroperitoneal approach. The patients were divided into three groups accordingly.
Results
At the immediate postoperative period, mortality rate equaled 2 (2.2%). The reasons were pulmonary embolism and sepsis. Statistically reliable data were obtained, confirming the advantages of midline laparotomic approach over the lateral retroperitoneal ones, which consisted in a shorter operative time, less pronounced pain syndrome, lesser blood loss, fewer postoperative days. The disadvantages were that enteroparesis occurred more often when the midline laparotomy was used in comparison to extended retroperitoneal or thoraco-phrenoretroperitoneal approaches.
Conclusion
Thus, open repairs of juxtarenal and pararenal aortic aneurysms have some specific technical and strategical features which are associated with intraoperative renal ischemia. During open surgical intervention, it is important to first consider the possibility of repair with midline laparotomy. However, lateral retroperitoneal approaches can also be used on a case-by-case basis noting their advantages and disadvantages.
