Aim: The aim of this paper was to compare in a retrospective study the outcome of aortoaortic graft (straight graft) versus aortoiliac graft (bifurcated graft) with regards to periprocedural and 30-day after surgery complications.
Methods: From January 2004 to December 2009 377 patients underwent elective open surgery for infrarenal abdominal aortic aneurysm. Data were collected in a dedicated database. Group A includes patients treated with straight graft (N.=186) whereas group B, patients treated with bifurcated graft (N.=191). Outcome data include duration of surgical procedure, blood loss, peri- and postprocedural complications, hospital stay, 30-day mortality and complications. Following some authors, we set our cut-off for choosing a bifurcated graft when one or both Iliac Arteries were wider than 18 mm in diameter and the patient had a reasonable life expectancy.
Results: duration of surgical procedure was 183 minutes in the group A vs. 216 minutes in the group B (P<0.01). Blood loss was 554 mL and 720 mL, in the groups A and B respectively (P<0.01). The difference between other results evaluated was not statistically significant.
Conclusion: In statistics terms, this retrospective study showed no relevant differences between straight graft and bifurcated graft with regard to mortality and major complications during the peri- and postoperatory period. Hence, as a conclusion, we could assert that if the iliac artery diameter is 18 mm a bifurcated graft could be used, without any increase in morbidity and mortality rates.
