Outcomes of EVAR with the endurant stent-graft system in patients with infrarenal ruptured abdominal aortic aneurysms: Is hostile anatomy a challenging factor?
European Journal of Radiology 2015 November
PURPOSE: To compare outcomes of endovascular aneurysm repair (EVAR) using the Endurant-I stent-graft system between patients who have ruptured abdominal aortic aneurysms (rAAAs) with normal and hostile anatomy.
MATERIALS AND METHODS: Patients with rAAAs who underwent EVAR between January 2008 and March 2014 were included in the study. There were 21 (70%) men and 9 (30%) women with a mean age of 70 years. Multidetector computed tomography (CT) angiography findings of the rAAA were classified according to the "Classification based on CT findings," and imaging planning was performed according to the Society of Interventional Radiology Guideline. Primary outcome measures (POM) were procedure-related mortality, 30-day mortality, and survival rate at 1 year. Secondary outcome measures (SOM) were technical success, open surgical conversion, complications, survival, relationship between size-severity of the rAAA and mortality, procedure time, hospital stay.
RESULTS: The periprocedural-EVAR mortality rate was 33%. The overall mortality rate without prehospital phase deaths was 40.0%. Seventy three percent of the patients with rAAAs had hostile anatomy. There were no statistically significant differences between the groups in POMs and SOMs (except mean hospital stay). Mean hospital stay was shorter in the normal anatomy group. The mortality rate was higher in patients with hematoma in both sides of the aorta and free intraperitoneal hematoma.
CONCLUSION: EVAR of rAAAs with hostile anatomy is feasible and off-label use of Endurant-I endografts could be expanded.
