Multicenter Study
Clopidogrel is not associated with major bleeding complications during peripheral arterial surgery.
Persistent variation in practice surrounds preoperative clopidogrel management at the time of vascular surgery. While some surgeons preferentially discontinue clopidogrel citing a perceived risk of perioperative bleeding, others will proceed with surgery in patients taking clopidogrel for an appropriate indication. The purpose of this study was to determine whether preoperative clopidogrel use was associated with significant bleeding complications during peripheral arterial surgery. ⋯ Patients undergoing peripheral arterial surgery in whom clopidogrel was continued either alone or as part of dual antiplatelet therapy did not have significant bleeding complications compared with patients taking no antiplatelet therapy or ASA alone at the time of surgery. These data suggest that clopidogrel can safely be continued preoperatively in patients with appropriate indications for its use, such as symptomatic carotid disease or recent drug-eluting coronary stents.

Comparative Study
Evaluating preventable adverse safety events after elective lower extremity procedures.
Improving patient safety has become a national priority. Patient safety indicators (PSIs) are validated tools to identify potentially preventable adverse events. No studies currently exist for evaluating lower extremity (LE) vascular procedures and the occurrence of PSIs. ⋯ Endovascular procedures were found to have lower mortality rates overall, but were found to have a greater number of safety events occur primarily due to bleeding complications in women and the elderly. PSIs were associated with advanced age, black race, and comorbidities. Adverse events added significant cost, occurred more frequently in teaching and large hospitals, and future organizational analysis may improve safety and reduce cost.

Endovascular abdominal aortic aneurysm (AAA) repair (EVAR) has been associated with lower operative mortality and morbidity than open surgery but comparable long-term mortality and higher delayed complication and reintervention rates. Attention has therefore been directed to identifying preoperative and operative variables that influence outcomes after EVAR. Risk-prediction models, such as the EVAR Risk Assessment (ERA) model, have also been developed to help surgeons plan EVAR procedures. The aims of this study were (1) to describe outcomes of elective EVAR at the Royal Brisbane and Women's Hospital (RBWH), (2) to identify preoperative and operative variables predictive of outcomes after EVAR, and (3) to externally validate the ERA model. ⋯ The outcomes of elective EVAR at the RBWH are broadly consistent with those of a nationwide Australian audit and recent randomized trials. Age and ASA score are independent predictors of midterm survival after elective EVAR. The ERA model predicts mortality-related outcomes and initial type I endoleak well for RBWH elective EVAR patients.

This article assesses the current mandates on conflict of interest issues as they affect the practice of community-based vascular surgery and the pharmaceutical and medical technology industries and expresses the views of a private practice vascular surgeon. Scenarios where conflict of interest may occur are presented with assessments on how these scenarios will play out if such mandates are enforced.

The physician/surgeon's interactions with industry have come under scrutiny in recent years for several reasons. Although some think that the professional medical association or society may provide an avenue to allow such interactions with less risk, there are concerns and challenges for such organizations as it relates to ethical and professional norms of their members. This is one surgeon's review of some pertinent information regarding what the professional medical society provides to its members and what role industry plays in the society's ability to provide these benefits. There is an exploration of the risks involved and practical methods to control inherent conflicts of interest involved in this interaction.
