What Happens If Peripheral Artery Disease (PAD) Is Left Untreated?

Peripheral Artery Disease (PAD) is one of the most serious circulation disorders affecting the legs. It develops when plaque builds up inside the arteries, reducing blood flow to the lower extremities. 

Many patients ignore early symptoms, assuming leg pain is simply part of aging. However, untreated PAD can have life-altering consequences. 

Early Signs of PAD 

Symptoms often begin gradually and may include: 

• Cramping or aching in the calves when walking 

• Pain that improves with rest 

• Cold or numb feet 

• Shiny or discolored skin 

• Slow-healing wounds 

• Hair loss on the legs 

Because symptoms may be subtle at first, patients often delay evaluation. 

The Progression of Untreated PAD 

Without treatment, PAD can worsen over time. 

As blood flow becomes more restricted, patients may develop: 

• Pain even at rest 

• Non-healing ulcers 

• Infection 

• Tissue death (gangrene) 

• Increased risk of amputation 

PAD is also a marker of systemic vascular disease. Patients with PAD are at significantly higher risk of heart attack and stroke. 

Early Treatment Changes Outcomes 

The earlier PAD is diagnosed, the more treatment options are available. A Texas vascular specialist can perform non-invasive testing and recommend: 

• Structured exercise programs 

• Medication management 

• Smoking cessation support 

• Angioplasty or stenting 

• Minimally invasive revascularization procedures 

At Texas Cardiac & Vascular Institute, many PAD procedures are performed in our office-based lab, allowing for efficient treatment without hospital delays. 

If you experience leg pain when walking or notice wounds that aren’t healing, evaluation should not wait.
