  1. EVAR vs. OAR: One Community Hospital’s Experience Westley Smith

  2. Background Abdominal Aortic Aneurysm (AAA) http://www.zenithstentgraft.com/patients/US/aaa/what/index.html

  3. Methods OAR 1.Large mid-line incision 2.Aneurysm dissected 3.Graft stitched into place 4.Aorta and Iliac Sutured Pictures taken from: http://www.guidant.com/webapp/emarketing/compass/comp.jsp?lev1=proc&lev2=aaa

  4. Methods EVAR 1. Small Infrainguinal Incision 2. Catheter Insertion 3. Portable C-Arm (radiography) 4. Deployment http://www.guidant.com/webapp/emarketing/compass/comp.jsp?lev1=proc&lev2=aaa http://www.llnl.gov/str/pdfs/05_00.3.pdf http://www.ziehm.com/ZiehmVision.htm Blood Flow

  5. Candidacy • Arteriosclerosis • Tortuosity • Infrarenal neck length/diameter • Iliac diameter • Patient preference

  6. Comorbidity and Demographics * Note. *Between groups Pulmonary Disease measured significantly different X2= 13.688, p= .001

  7. Anatomic & Demographic Comparison

  8. The Results

  9. Postoperative Results

  10. Conclusions Candidates for EVAR have tolerated a less invasive procedure without sacrificing postoperative results. The current study is indicative support for the surgeon’s continuation with EVAR – given amendable anatomical characteristics, and pending the long-term results of larger trial facilities.
