Comparative Study
Risk factors for readmission after lower extremity procedures for peripheral artery disease.
As pressure to contain health care costs increases, there has been greater scrutiny of readmissions in the vascular surgery population. The objective of this study was to evaluate postoperative readmissions after open and endovascular lower extremity (LE) procedures for peripheral artery disease (PAD). ⋯ Less invasive endovascular procedures were not associated with decreased readmission rates compared with open surgery. The overall readmission rate for claudicant patients was 10.7%, which was unexpectedly high. Predictors of readmission included male sex, longer hospital stays, hospital infection, elevated aspartate aminotransferase, and high numbers of medications ordered and dispensed. Further examination exploring reasons for readmission are required to decrease readmission rates in the vascular surgery population.

The Food and Drug Administration has approved devices for endovascular management of thoracic endovascular aortic aneurysm repair (TEVAR); however, limited data exist describing the outcomes of TEVAR for aneurysms attributable to chronic type B aortic dissection (cTBAD). This study was undertaken to determine the results of endovascular treatment of cTBAD with aneurysmal degeneration. ⋯ TEVAR for cTBAD with aneurysmal degeneration can be performed safely but spinal cord ischemia rates may be higher than previously reported. Liberal use of procedural adjuncts to reduce this complication, such as spinal drainage, is recommended. Reintervention is common, but long-term survival does not appear to be impacted by remediation.

Comparative Study
The importance of socioeconomic factors for compliance and outcome at screening for abdominal aortic aneurysm in 65-year-old men.
To evaluate compliance with screening and prevalence of abdominal aortic aneurysm (AAA) in relation to background data regarding area-based socioeconomic status. ⋯ Compliance with ultrasound screening for AAA differed between different geographical areas. In areas with low socioeconomic status, compliance rates were lower, whereas AAA prevalence was higher. The identification of contextual factors associated with low compliance is important to be able to allow targeted actions to increase efficacy of ultrasound screening for AAA. Targeted actions to increase compliance in those areas are being scientifically investigated and implemented.

The safety and feasibility of fenestrated/branched endovascular repair of acute visceral aortic disease in high-risk patients is unknown. The purpose of this report is to describe our experience with surgeon-modified endovascular aneurysm repair (sm-EVAR) for the urgent or emergent treatment of pathology involving the branched segment of the aorta in patients deemed to have prohibitively high medical and/or anatomic risk for open repair. ⋯ Urgent or emergent treatment of acute pathology involving the visceral aortic segment with fenestrated/branched endograft repair is feasible and safe in selected high-risk patients; however, the durability of these repairs is yet to be determined.

Lifelong surveillance is recommended for both endovascular aneurysm repair and acute, uncomplicated type B thoracic aortic dissection, though compliance remains a significant challenge. We sought to determine factors associated with failure to obtain recommended surveillance. ⋯ Despite a significant rate of reintervention following EVAR, TEVAR, and type B dissection, long-term compliance with surveillance is limited. In addition, predicting who is at risk of being lost to follow-up remains difficult. If current recommendations for lifelong surveillance are to be followed, coordinated protocols are required to capture EVAR, TEVAR, and type B dissection patients to ensure optimal follow-up for these patients. However, the lack of survival benefit in those with complete follow-up suggests that further study is needed with regard to ideal duration of long-term follow-up.
