Comparative Study
Differences in readmissions after open repair versus endovascular aneurysm repair.
Reintervention rates after repair of abdominal aortic aneurysm (AAA) are higher for endovascular repair (EVAR) than for open repair, mostly due to treatment for endoleaks, whereas open surgical operations for bowel obstruction and abdominal hernias are higher after open repair. However, readmission rates after EVAR or open repair for nonoperative conditions and complications that do not require an intervention are not well documented. We sought to determine reasons for all-cause readmissions within the first year after open repair and EVAR. ⋯ Total readmission rates within 1 year after elective AAA repair are greater after EVAR than after open repair. Reasons for readmission vary between the two cohorts but are related to the magnitude of open surgery after open repair, device issues after EVAR, and the usual cardiac and infectious complications after either intervention. Systems-based analysis of these causes of readmission can potentially improve patient expectations and care after elective aneurysm repair.

Comparative Study
An outcome analysis of endovascular versus open repair of blunt traumatic aortic injuries.
Aortic injury is the second most common cause of death after blunt trauma. Thoracic endovascular aortic repair (TEVAR) has been rapidly adopted as an alternative to the traditional open repair (OR) for treatment of traumatic aortic injury (TAI). This paradigm shift has improved the outcomes in these patients. This study evaluated the outcomes of TEVAR compared with OR for patients with TAI. ⋯ Compared with TEVAR, patients who underwent OR had three times higher odds to face a complication or in-hospital death. The mean total cost of TEVAR was not significantly different than OR. The findings support the use of TEVAR over OR for patients with TAI.

Lower extremity peripheral artery disease occurs mostly in the elderly and is associated with high mortality. Limited data are available regarding long-term mortality in patients with premature lower extremity atherosclerosis (PLEA). Our objective was to determine the all-cause mortality and its predictors in younger PLEA patients. ⋯ Patients with PLEA demonstrate high all-cause mortality. No traditional cardiovascular risk factors predicted mortality. Aspirin therapy at the time of first evaluation was a significant and independent predictor of improved survival in patients with PLEA.

Repair of saccular aortic aneurysms (SAAs) is frequently recommended based on a perceived predisposition to rupture, despite little evidence that these aneurysms have a more malignant natural history than fusiform aortic aneurysms. ⋯ While SAA were not found to have a higher growth rate than their fusiform counterparts, both clinical and radiologic follow-up is necessary, as a significant number ultimately require surgical intervention. Further clinical research is necessary to determine the optimal management of SAA.

Stent graft-induced new entry (SINE) has been increasingly observed after thoracic endovascular aortic repair (TEVAR) for aortic dissection. We investigated the mechanism of late distal SINE, prevention strategies, proper size selection of the stent graft, and implantation sequence. ⋯ The incidence of distal SINE seemed to be high; however, there were also low rates of death and complications after TEVAR for aortic dissection using stainless steel-based stent grafts. Complicated distal SINE can successfully be resolved by distal endograft implantation. Excessive oversizing of the distal stent graft, as measured by the true lumen area, may be a significant factor causing delayed distal SINE. Precise size selection is crucial for the distal end of the stent, especially for high taper ratio dissection pathology in which the implantation sequence of a distal small-sized stent graft first might be considered to prevent future distal SINE.
