In-Hospital Efficacy of Endovascular Aortic Repair in Patients With Impending Rupture versus Contained Rupture of Abdominal Aortic Aneurysms

Abstract

The purpose of our study was to compare the efficacy of endovascular aortic repair (EVAR) in patients with impending rupture of abdominal aortic aneurysm (IRAAA) versus contained rupture of abdominal aortic aneurysm (CRAAA). Of the 21 patients who underwent EVAR for infrarenal AAA from January 2009 toMay 2011, 11 did so for IRAAA and 10 for CRAAA. We compared their demographic andaneurysmal characteristics, comorbidities, complications, and clinical outcomes during hospitalization. The CRAAA group was younger than the IRAAA group. There were no group differences in AAA size, operation time, volume of contrast agent, length of hospital stay (LOHS), or preoperative LOHS. A small difference in mean intraoperative blood loss of ∼4 mL was noted, but was recognized as clinically insignificant. ICU stay and postoperative LOHS were greater in the CRAAA than in the IRAAA. One patient in the IRAAA group had a mild headache after EVAR. Four patients in the CRAAA group had postoperative complications: 1 had acute renal dysfunction; 1 had retroperitoneal infection; 1 had respiratory failure and myocardial infarction; and 1 died of respiratory tract infection and respiratory and cardiac failure. Patients undergoing EVAR for CRAAA have a higher incidence of postprocedural severe complications and death than patients undergoing EVAR for IRAAA.
