Readmissions, Reintervention Slightly Higher With EVAR
Account for more deaths with endovascular repair of aortic aneurysm than with open repair
FRIDAY, Jan. 7 (HealthDay News) -- Reinterventions and readmissions are modestly higher after endovascular abdominal aortic aneurysm (AAA) repair (EVAR) compared with open repair, and may diminish long-term survival, according to research published in the January issue of the Journal of Vascular Surgery.
Kristina A. Giles, M.D., of the Beth Israel Deaconess Medical Center in Boston, and colleagues evaluated the rate of reinterventions and readmission in 45,652 individuals undergoing EVAR and open repair for AAA to assess the effect of reinterventions on survival with the two approaches. Follow-up was six years.
The researchers found reintervention/readmission rates similar between the two repair method groups, but slightly higher after EVAR (7.6 versus 7.0 per 100 person-years). EVAR patients experienced more ruptures and more AAA-related interventions than those receiving an open repair. Reinterventions/readmissions accounted for 9.6 and 7.6 percent of deaths following EVAR and open repair, respectively.
"Reintervention and readmission are slightly higher after EVAR. Survival is negatively affected by reintervention or readmission after EVAR and open surgery, which likely contributes to the erosion of the survival benefit of EVAR over time," the authors write.
