AT VIVA16

LAS VEGAS (FRONTLINE MEDICAL NEWS) – A ‘fast-track” stenting method for endovascular abdominal aortic aneurysm repair (EVAR) enabled patients to be treated safely and effectively without general anesthetic or ICU admission, and with next-day discharge, Zvonimir Krajcer, MD, said at the 2016 Vascular Interventional Advances meeting.

Dr. Krajcer discussed the final results of the Prospective LIFE Registry , which followed 250 patients treated with the Ovation Abdominal Stent Graft platform , who had suitable femoral arteries to allow the use of the Perclose ProGlide Suture-Mediated Closure (SMC) System.

For the Fast-Track patients, vascular access, stent graft delivery, and deployment were successful. The Fast-Track EVAR protocol was successfully completed in 216 (87%) of the patients. In comparing the Fast-Track cohort (n = 216) to the non–Fast-Track cohort (n = 34), procedure time was found to be 84 vs. 110 minutes, the use of general anesthesia was 0% vs. 18%, and the need for ICU stay was 0% vs. 32%. Hospital stay for the two groups was 1.2 vs. 1.9 days, respectively.

Quality of life score improvement from baseline to 30 days as assessed via the EQ-5D questionnaire, was significantly greater in the Fast-Track patients, compared with the EVAR controls, said Dr. Krajcer, an interventional cardiologist at Texas Heart Institute and St. Luke’s Hospital, Houston, and a clinical professor of medicine at Baylor College of Medicine.

To determine adverse events, patients were followed through 1 month after treatment. The researchers found no device- or procedure-related major adverse events, abdominal aortic aneurysm (AAA) ruptures, surgical conversions, or AAA-related secondary interventions. One patient in the fast-track group died from acute respiratory failure. Overall, for the Fast-Track and control groups, the freedom from type I/III endoleak was 99% and 100%, respectively.

Dr. Krajcer reported that the 30-day hospital readmission rate in the LIFE study was 1.6%, compared to 8% reported for EVAR from the American College of Surgeons National Surgical Quality Improvement Program.

The economic analysis was performed comparing the Fast-Track patients to a control group, which consisted of a database of 8,306 patients treated with elective infrarenal EVAR at 3,750 U.S. hospitals based on inpatient discharge between 2012 and 2015. The researchers calculated costs related to access, anesthesia, ICU stay, and hospital stay.

The Fast-Track protocol showed $21,000 in perioperative cost savings relative to standard EVAR, largely driven by differences in hospital stay costs, according to Dr. Krajcer.

“Fast-track EVAR using the Ovation Prime stent graft is safe and feasible and lowers perioperative costs,” said Dr. Krajcer. “Our results warrant the establishment of a Fast-Track EVAR protocol in experienced EVAR centers,” he concluded.

Dr. Krajcer had nothing to disclose.
