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.

'Aneurysm Number' may help surgeons make treatment decisions
Aneurysms form as abnormal bulges over an artery, and, if ruptured, can lead to serious health complications or even death. Some can exist for a long time without rupturing, and surgery can be risky, so a parameter to help surgeons is needed. Researchers report in Physics of Fluids that they have developed a simple nondimensional parameter that depends on both geometry and flow waveform to classify the flow mode in both sidewall and bifurcation aneurysms.
