Multicenter Comparative Analysis of Late Open Conversion in Patients With Adherence and Nonadherence to Instructions for Use Endovascular Aneurysm Repair.

Purpose: The widespread adoption of endovascular aneurysm repair (EVAR) as preferred treatment modality for abdominal aortic aneurysm (AAA) has enlarged the number of patients needing open surgical conversion (OSC). The relationship between adherence to Instructions For Use (IFU) and EVAR long-term outcomes remains controversial. The aim of this study is to compare preoperative differences and postoperative outcomes between EVAR patients not adjusted to IFU and adjusted to IFU who underwent OSC.

Evaluation of the Bundle "Zero Surgical Site Infection" to Prevent Surgical Site Infection in Vascular Surgery.

Background: To compare the incidence of surgical site infections (SSIs) before and after the implementation of a bundle of care called "Zero Surgical Site Infection." Secondary goals included estimating measures of association and their potential impact, determining care management indicators in vascular surgery, and evaluating the level of compliance with the bundle.

Methods: This is a prospective observational study with a historic control group.
