Randomized Controlled Trial Comparative Study
Forced-Air Warming in Patients Undergoing Endovascular Procedures: Comparison between 2 Thermal Blanket Models.
The purpose of this study was to compare the efficiency between 2 thermal blanket models: the upper blanket and the underbody blanket in patient heating and hypothermia prevention during endovascular surgery. ⋯ We conclude that upper thermal blanket is more effective thanunderbody thermal blanket in patient warming and hypothermia prevention during endovascular abdominal aortic aneurysm repair and lower limb angioplasty after 150 min of anesthetic-surgical time duration.

Risk Factors Associated with Perioperative Myocardial Infarction in Major Open Vascular Surgery.
Among patients undergoing noncardiac surgery, major vascular surgery is associated with a high risk of perioperative myocardial infarction (MI). Currently, there are no perioperative MI risk calculators accounting for intraoperative and postoperative risk factors in vascular surgery patients. We aimed to investigate specific risk factors for perioperative MI after major open vascular surgery to determine which patients are at highest risk of MI and the association of perioperative MI with perioperative transfusion. ⋯ Among vascular surgery patients undergoing major open vascular surgery, surgical priority was the only preoperative risk factors independently associated with MI, and only postoperative variables such as nadir hematocrit and postoperative transfusion were associated with MI. This suggests minimizing intraoperative blood loss and prioritizing early intraoperative transfusion may be the potential targets for process improvement.

The Value of Carotid Endarterectomy as a Learning Tool for Trainees.
Carotid endarterectomy (CEA) intervention needs a specific training and a sufficient learning curve to obtain optimal results in terms of outcome. A formative program was settled up in a single academic center to optimize training of standard CEA procedures. This study aims to evaluate the 11-year results of the teaching CEA program. ⋯ With a defined CEA teaching program, trainees can obtain results similar to those of more experienced surgeons in terms of clinical outcome at the price of an increased intervention time.

Observational Study
Permanent Decline of Renal Function after Infrarenal Abdominal Aortic Aneurysm Repair-Frequency and Risk Factors.
Permanent renal function decline, and development and deterioration of chronic kidney disease (CKD) are associated with serious complications. How frequent is renal function decline after infrarenal abdominal aortic aneurysm (iAAA) repair according to current definitions and what are its risk factors, especially potentially modifiable ones? ⋯ A permanent decline of renal function 1 year after iAAA repair is frequent. Preexisting CKD, RAS ≥70%, OAR, and periprocedural AKI are independent risk factors, the latter 2 with additive effect.

Identifying the risk factors predisposing to aortic enlargement after thoracic endovascular aortic repair (TEVAR) is needed for DeBakey IIIb aortic dissection. The aim of the study is to assess the novel morphological features for DeBakey IIIb aortic dissection in predicting distal thoracic aortic enlargement after TEVAR. ⋯ The CTA-based morphological features described in this study might improve preoperative risk stratification of DeBakey IIIb aortic dissection, with categories II and III having higher risk of distal thoracic aortic enlargement after TEVAR.
