Endovascular aneurysm repair linked to higher readmission rates
Ruptured abdominal aortic aneurysms (rAAA) are responsible for nearly 2% of all deaths in U.S. men over the age of 65. Endovascular aneurysm repair (EVAR) has emerged as a newer and less invasive alternative to open repair for rAAA. But researchers from the University of Missouri School of Medicine have discovered that while EVAR is more commonly utilized for rAA, the odds of hospital readmission after EVAR are 1.5 times higher compared to traditional open repair.
