OBJECTIVE The treatment outcomes of ruptured visceral artery aneurysms (rVAAs) have been sparsely characterized, with no clear comparison between different treatment modalities. The purpose of this paper was to review the perioperative and long-term outcomes of open and endovascular interventions for intact visceral artery aneurysms (iVAAs) and rVAAs. METHODS This was a retrospective review of all treated VAAs at one institution from 2003 to 2013. Patient demographics, aneurysm characteristics, management, and subsequent outcomes (technical success, mortality, reintervention) and complications were recorded. RESULTS The study identified 261 patients; 181 patients were repaired (77 ruptured, 104 intact). Pseudoaneurysms were more common in rVAAs (81.8% vs 35.3% for iVAAs; P < .001). The rVAAs were smaller than the iVAAs (20.7 mm vs 27.5 mm; P = .018), and their most common presentation was abdominal pain; 29.7% were hemodynamically unstable. Endovascular intervention was the initial treatment modality for 67.4% (75.3% for rVAAs, 61.5% for iVAAs). The perioperative complication rate was higher for rVAAs (13.7% vs 1% for iVAAs; P = .003), as was mortality at 30 days (13% vs 0% for iVAAs; P = .001), 1 year (32.5% for rVAAs vs 4.1% for iVAAs; P < .001), and 3 years (36.4% for rVAAs vs 8.3% for iVAAs; P < .001). Lower 30-day mortality was noted with endovascular repair for rVAAs (7.4% vs 28.6% open; P = .025). Predictors of mortality for rVAAs included age (odds ratio, 1.04; P = .002), whereas endovascular repair was protective (odds ratio, 0.43; P = .037). Mean follow-up was 26.2 months, and Kaplan-Meier estimates of survival were higher for iVAAs at 3 years (88% vs 62% for rVAAs; P = .045). The 30-day reintervention rate was higher for rVAAs (7.7% vs 19.5% for iVAAs; P = .019) but was similar between open and endovascular repair (8.2% vs 15%; P = NS). CONCLUSIONS rVAAs have significant mortality. Open and endovascular interventions are equally durable for elective repair of VAAs, but endovascular interventions for rVAAs result in lower morbidity and mortality. Aggressive treatment of pseudoaneurysms is electively recommended at diagnosis regardless of size.
