In the early years of the society, the focus was primarily on the surgical treatment of arterial occlusive disease.

However, over time, the scope of the society's work expanded to include the treatment of all types of vascular disease.

The society's guidelines are developed by expert panels, based on the best available evidence, and are designed to help healthcare providers make informed decisions about the care of patients with vascular disease.

The PSO is dedicated to improving patient outcomes and reducing medical errors by collecting and analyzing data on adverse events and near misses in vascular surgery.

The PSO provides its members with tools and resources to promote a culture of safety and to reduce the risk of medical errors.

The VQI is a national registry that collects and analyzes data on the outcomes of vascular surgeries performed at participating institutions.

The VQI provides feedback to participating institutions to help them improve patient outcomes and reduce the risk of medical errors.

In addition, the VQI conducts research and provides educational programs focused on improving the quality of vascular surgery.
