Peripheral Artery Disease (PAD) is a serious circulatory condition that affects millions of Americans — yet it often goes undiagnosed. PAD occurs when fatty deposits narrow the arteries that supply blood to the limbs, most commonly the legs. Without proper blood flow, patients can experience pain, wounds that won’t heal, and in severe cases, tissue loss or amputation.
Dr. Shawn Poole, MD, MBA, RPVI, a vascular specialist at Northside Hospital, is working to raise awareness among primary care providers and patients about the importance of early detection and modern treatment options.
“Our goal is limb salvage through early diagnosis and personalized treatment,” Dr. Poole said. “PAD can be managed successfully when caught early.”
Recognizing the risks
PAD is closely linked to other chronic conditions such as high cholesterol, high blood pressure, diabetes, and chronic kidney disease, as well as tobacco use. Some people have no symptoms, while others experience leg pain during activity (claudication) that improves with rest.
At its most severe stage, critical limb ischemia, patients may develop persistent pain, ulcers, or gangrene, which can lead to limb loss if untreated.

Diagnosis and early intervention
Primary care teams play a key role in identifying PAD early. A physical exam may reveal weak or absent pulses in the feet or lower legs. Simple, noninvasive tests, such as the Ankle-Brachial Index (ABI), arterial duplex ultrasound, or CT angiography, can confirm the diagnosis.
Dr. Poole encourages prompt referral to a vascular specialist when PAD is suspected. “Timely referral can make the difference between a minor intervention and a major amputation,” he said.
Comprehensive medical management
The first line of treatment focuses on improving circulation and preventing disease progression. This includes:
- Antiplatelet and cholesterol-lowering medications
- Smoking cessation
- Supervised exercise or walking programs
These evidence-based steps not only relieve symptoms but also reduce the overall risk of heart attack and stroke.
Advanced revascularization options
When additional treatment is needed, Northside offers a full range of minimally invasive and surgical options to restore blood flow and preserve limb function.
Endovascular procedures are often performed on an outpatient basis using tiny incisions in the femoral, radial, or pedal arteries. New technologies — such as intravascular lithotripsy for calcified blockages and laser atherectomy for complex lesions — enable physicians to treat even the most challenging cases with precision and accuracy.
For patients requiring more extensive repair, open surgical procedures like bypass grafting or endarterectomy may be recommended.
Northside’s hybrid operating rooms combine both capabilities in one setting, enabling surgeons to perform complex, multilevel repairs with advanced imaging and full anesthesia support.
The power of collaboration
Dr. Poole emphasizes that the most effective PAD care is team-based — involving primary care providers, vascular specialists, and patients working together to manage risk factors and maintain circulation.
“Together, we can achieve limb salvage,” Dr. Poole said. “With the right tools, early action, and personalized care, patients can keep moving and live healthier, longer lives.”
