National trends in utilization and outcome of thoracic endovascular aortic repair for traumatic thoracic aortic injuries
Abstract
Endovascular repair of traumatic thoracic aortic injuries (TTAI) is an alternative to conventional open surgical repair. Single-institution studies have shown a survival benefit with thoracic endovascular aortic repair (TEVAR), but whether this is being realized nationally is not clear. The purpose of our study was to document trends in the increase in use of TEVAR and its effect on outcomes of TTAI nationally. Patients admitted with a TTAI between 2005 and 2011 were identified in the National Inpatient Sample. Patients were grouped by treatment into TEVAR, open repair, or nonoperative management. Primary outcomes were relative use over time and in-hospital mortality. Secondary outcomes included postoperative complications and length of stay. Multivariable logistic regression was performed to identify independent predictors of mortality. Included were 8384 patients, with 2492 (29.7%) undergoing TEVAR, 848 (10.1%) open repair, and 5044 (60.2%) managed nonoperatively. TEVAR became the dominant treatment option for TTAI during the study period, starting at 6.5% of interventions in 2005 and accounting for 86.5% of interventions in 2011 (P < .001). Nonoperative management declined concurrently with the widespread of adoption TEVAR (...Continue Reading

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.
