Retroperitoneal Approach to Abdominal Aortic Aneurysms / 日本心臓血管外科学会雑誌

ABSTRACT

To evaluate the efficacy of the retroperitoneal approach (RP) when compared with the transperitoneal approach (TP) in elective aortoiliac reconstruction, 41 cases were reviewed. From February 1987 through October 1991, 16 patients underwent aortoiliac reconstruction through the TP approach and 25 patients underwent operation through the RP approach for abdominal aortic aneurysms (AAA). The TP approach was associated with larger intraoperative blood loss (648.6±416.5ml) when compared with the RP approach (357.7±208.9ml) (<i>p</i><0.01). The TP approach was associated with greater intraoperative blood transfusion (2093.8±1179.0ml) when compared with the RP approach (1010.4±905.3ml) (<i>p</i><0.01). Both groups had similar operative times. Postoperative initiation of oral water intake was prolonged in the TP group (50.2±27.4hr) when compared with the RP group (22.3±8.9hr) (<i>p</i><0.01). Postoperative initiation of walking training was prolonged in the TP group (88.7±37.1hr) when compared with the RP group (60.1±23.2) (<i>p</i><0.01). This experience demonstrates that the RP approach is a preferable alternative to the TP approach in elective aortoiliac reconstruction.
