Midterm outcome of endovascular repair of ruptured isolated iliac artery aneurysms


Hechelhammer, L; Rancic, Z; Pfiffner, R; Mayer, D; Meier, T; Lachat, M; Pfammatter, T (2010). Midterm outcome of endovascular repair of ruptured isolated iliac artery aneurysms. Journal of Vascular Surgery, 52(5):1159-1163.

Abstract

PURPOSE: This study analyzed the clinical and morphologic outcomes of endovascular treatment of ruptured isolated iliac artery aneurysms (RIIAA) at midterm follow-up. METHODS: Eleven patients with RIIAA (1 woman, 10 men; mean age, 73 years; mean IIAA diameter, 69.1 mm) were identified in a single-center database of patients who underwent endovascular aortoiliac aneurysm repair between April 2001 and December 2009. Devices inserted included 9 leg endografts in 7 patients (Excluder, n = 7; Zenith, n = 2), 3 bifurcated stent grafts in 3 patients (Excluder), and 1 aortouniiliac stent graft in 1 patient (Zenith). Endovascular occlusion of the internal iliac artery or its branches was performed in all cases by coils (n = 10) or Amplatzer occluder plug (n = 1). Immediately after endovascular aneurysm exclusion, a computed tomography (CT) angiography was obtained in nine patients. Except for this adjunct postimplantation CT scanning, the imaging follow-up was the same as for nonruptured aortoiliac aneurysms at 3, 6, and 12 months and annually thereafter. RESULTS: Mean delay from hospital admission to intervention was 78.5 minutes. Mean intervention time was 150 minutes. The assisted primary technical success rate was 100%. Median lengths of stay were 2 days in the intensive care unit and 13 days in the hospital. Abdominal compartment syndrome developed in three patients who received open abdomen treatment. The 30-day mortality was 18%. The mean follow-up was 23 months (range, 0-69 months). There were no late deaths during the follow-up. There was no need for late surgical conversion. Aneurysm sac shrinkage (defined as >5 mm) was recorded in five patients, whereas the sac diameter remained stable in four. There was no patient with aneurysm sac growth. Additional stent graft insertion as the only secondary intervention for a type Ib leak was performed. Type II endoleaks (primary and secondary) were found in 36% and secondary Ib in 9% of the patients. CONCLUSION: Emergency stent grafting of RIIAA is feasible and safe with good midterm outcome.
