INTRODUCTION This study hypothesized that preoperative statin therapy would have a protective effect on patients undergoing elective abdominal aortic aneurysm (AAA) repair and that the risk-reduction effect of these agents would result in a reduction in subsequent total hospital costs. METHODS All patients who underwent an elective endovascular AAA repair (EVAR) or open AAA repair (OAR) between 2004 and 2007 were retrospectively reviewed. Clinical end points included postoperative days, length of hospital stay, postoperative complications (myocardial infarction, stroke, renal failure, hemorrhage, pneumonia, urinary tract infection, wound infection), and 30-day mortality. The financial end point was total hospital cost associated with the procedure. RESULTS We identified 401 patients, consisting of 173 EVAR patients (43%) and 228 OAR (57%). Despite a higher Society for Vascular Surgery risk score, the EVAR statin cohort had significantly reduced postoperative days (1.9 +/- 0.2 vs 2.3 +/- 0.3, P < .05) and hospital length of stay (2.3 +/- 0.3 vs 2.8 +/- 0.4, P < .05) compared with the nonstatin EVAR cohort. Postoperative complications (4.4% vs 14.7%, P < .05) and the mortality rate (0.0% vs 5.9%, P < .05) were significantly decreased in the OAR statin cohort compared with the nonstatin OAR cohort and trended to be decreased in the EVAR statin group. Statin therapy translated into a lower total cost per patient of

3,792 for OAR (P < .05). CONCLUSION With respect to both clinical outcome measures and subsequent resource utilization, statin therapy is associated with a beneficial effect in patients undergoing elective AAA repair. These data suggest that preoperative statin therapy should be an integral part of the risk optimization for patients undergoing AAA repair.

INTRODUCTION Within the context of healthcare system reform, the cost efficacy of lower extremity revascularization remains a timely topic. The impact of an individual patients socioeconomic status represents an under-studied aspect of vascular care, especially with respect to longitudinal costs and outcomes. The purpose of this study is to examine the relationship between socioeconomic status and clinical outcomes as well as inpatient hospital costs. METHODS A retrospective femoropopliteal revascularization database, which included socioeconomic factors (household income, education level, and payor status), in addition to standard demographic, clinical, anatomical, and procedural variables were analyzed over a 3-year period. Patients were stratified by income level (low income [LI] <200% federal poverty level [

Data were analyzed with univariate and multivariate techniques. RESULTS A total of 187 cases were identified with complete data for analysis, 146 in the LI and 41 in the HI cohorts. LI patients differed from HI patients by mean age (66.2 +/- 1.0 vs 61.8 +/- 1.5 years, P = .04), high school graduate rate (51.4% vs 85.4%, P < .001), presence of tissue loss (30.1% vs 14.6%, P = .05), female gender (43.7% vs 22.0%, P = .01) and preoperative statin use (45.8% vs 75.6%, P < .001). There were no differences with respect to other comorbidities including smoking status, presence of diabetes, renal insufficiency, anatomic factors or treatment modality (open vs endovascular). Ninety-seven patients underwent endovascular revascularization. The following outcomes were noted in the endovascular subset of LI and HI patients respectively: primary assisted patency (66% vs 71%, P = NS) and 12-month cost-per-day of patency (

40.47 +/- 4.63, P = .07). Of the 77 patients with critical limb ischemia, 19 underwent eventual amputation. Multivariate analysis demonstrated that income above 100% of the federal poverty line was protective against limb loss (odds ratio 0.06, 95% confidence interval 0.01-0.51, P < .001). CONCLUSION Income level correlates with advanced presentation, advanced age, and lack of statin use. Although primary assisted patency rate is not affected by income status, an increased cost-per-day of patency and inferior limb salvage is found in lower income patients.

INTRODUCTION Traumatic aortic injury (TAI) is a rare yet highly lethal injury associated with blunt force deceleration injury. The adoption of thoracic endovascular aortic repair (TEVAR) has become a safer option than traditional open repair. The purpose of this study is to review a rural trauma center experience with TAI. METHODS A retrospective analysis was performed, reviewing all patients who presented with TAI between 2000 and 2009. Clinical, anatomical, and procedural variables of all cases were systematically reviewed. Clinical endpoints included mortality, and aortic-related mortality, and hospital length of stay. The study population was stratified by those that underwent surgical repair (SR) and those managed medically (MM). RESULTS Fifty-six patients presented with blunt TAI; 35 patients (62.5%) were surgically repaired (22 open, 13 TEVAR), while 21 (37.5%) were MM. The only difference in comorbidities was a higher rate of coronary artery disease in MM. Mean hospital arrival time (SR, 188.6 ± 30.3 minutes, MM, 253 ± 65.3 minutes), aortic injury grade (SR, 2.7 ± 0.1; MM, 2.3 ± 0.2), and injury severity score were not significantly different between the groups. Head Abbreviated Injury Score (AIS) was worse in the MM group, while chest AIS was worse in the SR group (P < .05). There were nine (42.9%) deaths in the MM group, while there were only two (5.7%) in the SR group (P < .001). There was no significant difference in aortic-related mortality. Mean follow-up time was not statistically different. CONCLUSION These data provide a group of stable patients to examine the management of TAI in the endovascular era. The low aortic-related mortality in the MM group demonstrates that there is time for a thorough evaluation in patients sustaining TAI who arrive without hemodynamic instability.
