OBJECTIVE: To date, there are no published reports comparing hemodynamically (Hd)-stable and Hd-unstable patients with ruptured abdominal aortic aneurysms (r-AAAs) undergoing endovascular aneurysm repair (EVAR). This study evaluates outcomes of EVAR for r-AAA based on patient's Hd status METHODS: From 2002 to 2011, 136 patients with r-AAAs underwent EVAR and were categorized into two groups based on systolic blood pressure (SBP) measurements before EVAR: 92 (68%) Hd-stable (SBP ≥ 80 mm Hg) and 44 (32%) Hd-unstable (SBP <80 mm Hg for >10 minutes). All data were prospectively entered in a database and retrospectively analyzed. Outcomes included 30-day mortality, postoperative complications, the need for secondary reinterventions, and midterm mortality. The effect of potential predictors on 30-day mortality was assessed by χ(2) and logistic regression. RESULTS: Of the 136 r-AAA patients with EVAR, the Hd-stable and Hd-unstable groups had similar comorbidities (coronary artery disease, 63% vs 59%; hypertension, 72% vs 75%; chronic obstructive pulmonary disease, 21% vs 26%; and chronic renal insufficiency, 18% vs 18%), mean AAA maximum diameter (6.6 vs 6.4 cm), need for on-the-table conversion to open surgical repair (3% vs 7%), and incidences of nonfatal complications (43% vs 38%) and secondary interventions (23% vs 25%). Preoperative computed tomography scan was available in significantly fewer Hd-unstable patients (64% vs 100%; P < .05). Compared with Hd-stable patients, the Hd-unstable patients had a significantly higher intraoperative need for aortic occlusion balloon (40% vs 6%; P < .05), mean estimated blood loss (744 vs 363 mL; P < .05), incidence of developing abdominal compartment syndrome (ACS; 29% vs 4%; P < .01), and death (33% vs 18%; P < .05). ACS was a significant predictor of death; death in all r-EVAR with ACS was significantly higher compared with all r-EVAR without ACS (10 of 17 [59%] vs 22 of 119 [18%]; P < .01). CONCLUSIONS: EVAR for r-AAA is feasible in Hd-stable and Hd-unstable patients, with a comparable incidence of conversion to open surgical repair, nonfatal complications, and secondary interventions. Hd-stable patients have reduced mortality at 30 days, whereas Hd-unstable patients require intraoperative aortic occlusion balloon more frequently, and have an increased risk for developing ACS and death.
