Randomized Controlled Trial Multicenter Study Comparative Study
Statin therapy is associated with improved survival after endovascular and open aneurysm repair.
The relationship between numerous risk factors and perioperative mortality after cardiovascular surgery has been studied extensively. While improved perioperative survival and fewer cardiovascular events have been related to statin therapy, its effect on long-term survival after aneurysm repair remains to be elucidated. The aim of this study is to determine the effect of statin therapy on long-term survival after open and endovascular aneurysm repair and to identify other cardiovascular and patient-related risk factors in this respect. ⋯ Despite the limitations of a post-hoc analysis of a prospectively maintained trial, we conclude that statin therapy at the beginning of the trial is independently associated with improved long-term survival after open or endovascular aneurysm repair, while age above 70 years, a history of cardiovascular disease, and tobacco use are associated with decreased long-term survival.

Multicenter Study Comparative Study
Carotid stenting versus endarterectomy in patients undergoing reintervention after prior carotid endarterectomy.
Outcomes for patients undergoing intervention for restenosis after prior ipsilateral carotid endarterectomy (CEA) in the era of carotid angioplasty and stenting (CAS) are unclear. We compared perioperative results and durability of CAS vs CEA in patients with symptomatic or asymptomatic restenosis after prior CEA and investigated the risk of reintervention compared with primary procedures. ⋯ In the VSGNE, CEA and CAS showed statistically equivalent outcomes in asymptomatic and symptomatic patients treated for restenosis after prior ipsilateral CEA. However, regardless of symptom status, the risk of reintervention was increased compared with patients undergoing primary CEA.

Multicenter Study Observational Study
The need for treatment of hemodynamic instability following carotid endarterectomy is associated with increased perioperative and 1-year morbidity and mortality.
The objective of this study was to evaluate the outcomes of patients after carotid endarterectomy (CEA) who developed postoperative hypertension or hypotension requiring the administration of intravenous vasoactive medication (IVMED). ⋯ Postoperative hypertension requiring IVMED after CEA is associated with increased perioperative mortality, stroke, and cardiac complications, whereas significant postoperative hypotension is associated with increased perioperative mortality, cardiac, or stroke complications, as well as increased 1-year death or stroke following CEA. The utilization of IVMED varied across centers and, as such, further investigation into this practice needs to occur in order to improve outcomes of these at-risk patients.
