Atherosclerosis Common Etiology • 30-60% of pts with PVD have carotid disease • 50-60% of pts with carotid disease have coronary disease • 10% of pts with coronary disease have carotid disease
Results of Coronary Angiograms in 634 Patients with PAD 8.5%
Patient Survival by ABI . Newman et al ATVB 1999;19; 538-545
Five year mortality ratesPVD versus Cancer *Criqui M. Presentation: Vascular Medicine of the Lower Extremities at the American Diabetes Association’s Scientific Sessions June 1999
PVD ….What are the goals? • Asymptomatic – treat risk factors • Claudication – medical therapy or revascularization to improve symptoms • Critical Limb Ischemia – prevent amputation and limb loss
Diagnosis • Non-invasive • Bedside Ankle-Brachial Index • Lower extremity Segmental Pressures and PVRs • Arterial Duplex imaging • MRA • CTA • Invasive • Angiograpy
Disease Patterns Non-Diabetics Diabetics

Conclusions • Peripheral Vascular Disease is very prevalent in patients with cardiac disease • PVD is underdiagnosed and undertreated • High Mortality with PVD – usually due to cardiac causes • There are many revascularization options available to patients to improve quality of life
Patient Preference Percutaneous Surgical
