Comparative Study
A comparison of outcomes associated with carotid artery stent placement performed within and outside clinical trials in the United States.
A discrepancy between characteristics of patients treated with carotid angioplasty and stent placement (CAS) within and outside clinical trials, particularly characteristics with direct impact on clinical outcome, may limit generalization of clinical trial results. The objective of this study was to identify differences in demographic and clinical characteristics and outcomes related to CAS in patients treated within clinical trials and those treated outside clinical trials in a large national cohort. ⋯ Our results suggest that CAS procedures performed as part of clinical trials was associated with lower rates of in-hospital mortality and composite endpoint of stroke, cardiac events, and death in United States. These findings highlight the need for strategies that ensure appropriate adoption of CAS to ensure that the benefits observed in clinical trials can be replicated in general practice.

Loeys-Dietz syndrome is a recently described genetic connective tissue disorder. The syndrome is associated with multiple nonvascular phenotypic anomalies but also aggressive arteriopathy, which has so far principally been shown to cause aortic root dilatation with subsequent dissection and rupture. We report the first ever case of a young man diagnosed with Loeys-Dietz syndrome with asymptomatic large bilateral popliteal artery aneurysms. We have successfully resected these aneurysms and revascularized with synthetic graft.

The purpose of this report was to present abnormal posttraumatic cold intolerance in patients that previously underwent repair of arterial injuries after civilian upper limb trauma in our institution. ⋯ Abnormal cold intolerance is frequently seen in patients with a history of arterial repair in upper limb trauma. It is associated with significant functional impairment. Concomitant nerve injury and involvement of the subclavian or axillary artery are the major predisposing factors for development of cold intolerance after upper limb trauma.

Review Meta Analysis
Locoregional anesthesia for endovascular aneurysm repair.
This was a systematic review and meta-analysis of the mode of anesthesia and outcome after endovascular aneurysm repair (EVAR). ⋯ The absence of randomized data is a major hurdle to understanding the effect of anesthetic technique on morbidity after EVAR. The data presented are encouraging in selected patients. The use of locoregional anesthesia for EVAR should be further investigated with better reporting of aneurysm morphology to clarify its potential benefits and identify the subgroups that will derive greatest benefit.

Although large randomized studies have established the efficacy and safety of carotid endarterectomy (CEA) and, recently, carotid artery stenting (CAS), the under-representation of women in these trials leaves the comparison of risks to benefits of performing these procedures on women an open question. To address this issue, we reviewed the hospital outcomes and delineated patient characteristics predicting outcome in women undergoing carotid interventions using New York and Florida statewide hospital discharge databases. ⋯ Databases reflecting real-world practice performance and management of carotid disease in women suggest that CEA compared with CAS has overall better perioperative outcomes in women. Importantly, CAS is associated with significantly higher morbidity in certain clinical settings and this should be taken into account when choosing a revascularization procedure.
