Abstract

Time to discharge has decreased for aortic surgery since the advent of endovascular aortic aneurysm repair (EVAR), partially due to improved perioperative management. We aimed to investigate outcomes and risk factors associated with prolonged intubation following EVAR. The Vascular Study Group of New England (VSGNE) database was queried to select all patients who underwent elective EVAR between January 2003 and December 2014. Patients who were not extubated in the operating room were classified as having prolonged intubation. Patients requiring prolonged intubation were compared with those extubated in the operating room using t-test and chi-square statistics. Kaplan-Meier survival analyses estimated all-cause mortality. Independent predictors associated with prolonged intubation, including postoperative pneumonia or respiratory failure, were examined using multivariable logistic regression. A total of 3,979 patients were identified within the elective EVAR VSGNE data set, among whom 5.2% required prolonged intubation. Patients with prolonged intubation were older, more frequently female, non-Hispanic, had larger aneurysms, and had a more frequent diagnoses of diabetes, congestive heart failure, coronary artery disease, ejectio...Continue Reading

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
