The UW Medicine Regional Vascular Center provides comprehensive services for patients with circulatory problems and their referring healthcare providers throughout a five-state region: Washington, Wyoming, Alaska, Montana and Idaho (WWAMI). Our vascular experts in arterial, venous, and lymphatic disease work with radiology and cardiology specialists to determine the appropriate diagnostic imaging and medical or surgical treatment options. As a regional resource, we provide care that is not available in smaller communities. The center treats more patients with ruptured abdominal aortic aneurysms (rAAA) annually than any other healthcare facility in the WWAMI region and we have also been internationally recognized for creating an emergency protocol that dramatically reduced the average mortality rate for rAAA patients.
