Peripheral Arterial Disease Treatment in Pasadena, TX

What Is Peripheral Arterial Disease (PAD)?

Peripheral arterial disease (PAD) is a common and serious circulatory condition that occurs when the arteries supplying blood to the limbs — most commonly the legs — become narrowed or blocked due to atherosclerosis, the progressive buildup of fatty deposits (plaques) within the arterial walls. As plaque accumulates, the arteries stiffen and their internal diameter narrows, progressively reducing the volume of oxygen-rich blood that can reach the muscles and tissues of the lower extremities.

PAD affects an estimated 8–12 million Americans and becomes increasingly prevalent with age. Beyond its direct impact on leg health and mobility, PAD is an important indicator of systemic atherosclerosis — meaning patients with PAD are at significantly elevated risk for heart attack and stroke. Early diagnosis and treatment are essential to both preserve limb function and reduce cardiovascular risk.

What Causes Peripheral Arterial Disease?

PAD is primarily caused by atherosclerosis — the same process that causes coronary artery disease and carotid artery disease. Fatty deposits accumulate within the inner lining of the arterial wall over years and decades, gradually narrowing the vessel and restricting blood flow. A number of risk factors accelerate this process:

• Smoking: The single most significant modifiable risk factor for PAD. Cigarette smoking dramatically accelerates atherosclerosis and is strongly associated with more severe and rapidly progressive disease.
• Diabetes: Chronically elevated blood sugar damages the arterial walls, promotes inflammation, and accelerates plaque formation. Diabetic patients tend to develop PAD at a younger age and in the smaller vessels of the lower leg and foot.
• High blood pressure (hypertension): Sustained elevated pressure damages arterial walls and promotes endothelial dysfunction, accelerating atherosclerotic plaque buildup.
• High cholesterol (hyperlipidemia): Elevated LDL cholesterol contributes directly to plaque accumulation within arterial walls.
• Advancing age: The prevalence of PAD increases significantly after age 50, and more steeply after age 65.
• Obesity: Excess body weight promotes inflammation, insulin resistance, and hypertension — all of which accelerate arterial disease.
• Family history: A family history of PAD, heart attack, or stroke increases individual risk.
• Chronic kidney disease: Impaired kidney function is independently associated with accelerated cardiovascular and peripheral arterial disease.

What Are the Symptoms of Peripheral Arterial Disease?

PAD symptoms range from mild to severe depending on the degree of arterial narrowing and the number of vessels affected. It is important to note that up to half of all PAD patients have no symptoms at all or attribute their symptoms to aging — making awareness of risk factors critical. When symptoms do occur, they may include:

• Intermittent claudication: The most classic symptom — cramping, aching, or fatigue in the calf, thigh, or buttock muscles that reliably occurs with walking or physical exertion and resolves with a few minutes of rest. The location of claudication reflects the level of arterial blockage.
• Leg weakness or numbness: Feelings of heaviness, weakness, or reduced sensation in the legs, particularly during activity.
• Coldness in the lower leg or foot: A noticeable difference in temperature between one limb and the other, or between the foot and the upper leg.
• Skin color changes: Pale, dusky, or bluish discoloration of the skin of the legs or feet, particularly when elevated.
• Non-healing sores or wounds: Ulcers on the toes, feet, or lower legs that are slow to heal or fail to heal are a serious sign of significantly reduced arterial blood supply.
• Weak or absent pulses: Diminished pulse strength in the feet or ankles, detected on physical examination.
• Hair loss or shiny skin on the legs: Loss of leg hair and changes in skin texture can signal chronic poor circulation.
• Erectile dysfunction: In men, PAD affecting the pelvic arteries can contribute to erectile dysfunction due to reduced blood flow.
• Rest pain: In advanced PAD, severe burning or aching pain in the feet and toes that occurs at rest — particularly at night — indicates critical limb ischemia, a limb-threatening emergency requiring prompt intervention.

If you are experiencing any of these symptoms, do not delay evaluation. Contact Minimally Invasive Specialists of Texas at (832) 583-2246 for prompt assessment in Pasadena, TX .

How Is PAD Diagnosed?

Accurate diagnosis of PAD begins with a thorough clinical evaluation and is confirmed through non-invasive and, when needed, invasive imaging studies. At Minimally Invasive Specialists of Texas, our diagnostic approach includes:

• Ankle-Brachial Index (ABI): A simple, non-invasive test that compares blood pressure measured at the ankle with blood pressure at the arm. A low ABI ratio indicates reduced arterial flow to the leg and is the standard first-line diagnostic test for PAD.
• Vascular Ultrasound (Duplex Doppler): Our team performs comprehensive vascular ultrasound studies to visualize the arteries of the leg, measure flow velocities, and localize the sites of stenosis or occlusion without radiation or contrast dye.
• CT Angiography (CTA): A rapid, detailed imaging study that maps the entire arterial tree from the aorta to the feet using intravenous contrast, providing precise anatomic detail for treatment planning.
• MR Angiography (MRA): An alternative to CTA that uses magnetic resonance imaging to visualize the arteries without radiation; particularly useful in patients with contrast allergy or impaired kidney function.
• Catheter Angiography: The gold standard for arterial imaging, performed by our interventional radiologists in cases where endovascular treatment is planned. A catheter is inserted into the artery and contrast is injected under fluoroscopic guidance to precisely map the location and severity of arterial disease — often followed immediately by treatment in the same session.

How Is Peripheral Arterial Disease Treated at Minimally Invasive Specialists of Texas?

Treatment for PAD at Minimally Invasive Specialists of Texas is individualized based on the severity of symptoms, the location and extent of arterial disease, and each patient’s overall health and goals. Our approach combines risk factor management, lifestyle modification, and — when indicated — minimally invasive endovascular intervention:

• Lifestyle Modification: Smoking cessation is the single most impactful intervention for slowing PAD progression and improving outcomes. A heart-healthy diet, regular supervised exercise therapy, and weight management are all foundational components of PAD care.
• Medical Management: Antiplatelet medications (such as aspirin or clopidogrel) reduce clotting risk and cardiovascular events. Statins lower cholesterol and stabilize arterial plaques. Blood pressure and diabetes medications are optimized to control the underlying conditions that accelerate disease progression.
• Supervised Exercise Therapy: Structured, supervised walking programs are a highly effective, evidence-based treatment for claudication — improving walking distance, quality of life, and cardiovascular health significantly over time.
• Percutaneous Transluminal Angioplasty (PTA): A catheter-based procedure in which a small balloon is guided to the site of arterial narrowing and inflated to compress the plaque and widen the vessel, restoring blood flow. Angioplasty is highly effective for focal stenoses and can be performed through a small needle puncture under local anesthesia.
• Stent Placement: When angioplasty alone is insufficient — particularly for longer or more complex lesions — a metal stent is deployed within the treated artery to hold it open and maintain patency over time. Our team used this approach to successfully treat a 63-year-old woman with diabetes and hypertension who presented with severe bilateral common iliac artery narrowing, debilitating thigh cramping, and an inability to walk to her mailbox. Following bilateral iliac stent placement, she regained the ability to ambulate without difficulty.
• Atherectomy: A catheter-based technique that uses a rotating or laser device to physically remove or vaporize plaque from within the artery, used in select cases where calcified plaque is resistant to balloon dilation alone.
• Bypass Surgery: Surgical bypass — in which a graft is used to reroute blood around a blocked artery segment — may be recommended for patients with complex, extensive arterial disease not amenable to catheter-based treatment, or when endovascular approaches have failed.

Our interventional radiology team at Minimally Invasive Specialists of Texas tailors every treatment plan to the individual patient. We also manage closely related vascular conditions including deep venous thrombosis, chronic venous disease, and dialysis access.
