| Popis: | Background Rupture of an iliac artery aneurysm is rare but could be catastrophic unless it is treated with an appropriate strategy. We reviewed our 10-year institutional experience in treating iliac artery aneurysms to elucidate the effectiveness of open surgical repair strategies for ruptured iliac artery aneurysms in terms of short- and long-term postoperative results. Methods A total of 26 patients (men/women = 22/4), with a mean age of 72 years, underwent open repair of iliac artery aneurysm with or without rupture (unruptured/ruptured = 15/11) between January 2001 and April 2010. There was no difference in the distribution of aneurysm morphology between the unruptured and ruptured groups, and 20 (76.9%) of the 26 patients had aneurysms involving unilateral or bilateral internal iliac arteries. Long-term event-free survival rates and freedom from secondary intervention were analyzed using the Kaplan–Meier method (follow-up: 55 ± 39 and 40 ± 25 months in the unruptured and ruptured groups, respectively). Results There was no difference in the time of surgery between the two groups (351 ± 118 and 348 ± 152 minutes in the unruptured and ruptured groups, respectively), but the ruptured group showed greater blood loss/min (time of surgery) and transfusion volume than the unruptured group. The early postoperative mortality was 6.7% in the unruptured group and 0% in the ruptured group ( p = 0.557). There was no difference in the number of postoperative morbidities between the two groups, but the ruptured group showed significantly greater C-reactive protein, lactate dehydrogenase, and total bilirubin levels than the unruptured group. The cardiovascular event-free survival rate at 5 years was 93.3% and 100.0% in the unruptured and ruptured groups, respectively. The secondary intervention-free rate at 5 years was 100.0% and 90.0% in the unruptured and ruptured groups, respectively. Conclusions The short- and long-term postoperative mortality rates after open repair for iliac artery aneurysms were satisfactorily low and similar in unruptured and ruptured groups. This suggests that open repair strategies remain as a reliable treatment option to obtain successful postoperative results in patients with rupture of an iliac artery aneurysm. |
