Peripheral Arterial Disease Treatment in Pasadena, TX

Understanding Peripheral Arterial Disease

Peripheral arterial disease (PAD) develops when fatty plaque deposits — a process called atherosclerosis — accumulate within the walls of the arteries that supply blood to the legs and feet, progressively narrowing the vessel diameter and reducing oxygen delivery to the limb tissues. PAD is not simply a leg problem; it is a manifestation of systemic cardiovascular disease, and its presence indicates that the same plaque-building process is almost certainly affecting the heart and brain as well.

This is why PAD is considered a critical warning sign — patients diagnosed with PAD have a significantly elevated risk of heart attack, stroke, and cardiovascular death. Approximately 8–12 million Americans are affected, and the condition becomes more prevalent with age, affecting roughly 12–20% of adults over 60. Despite its frequency, PAD remains underdiagnosed because many patients attribute their symptoms to normal aging or dismiss them as muscle fatigue. At Minimally Invasive Specialists of Texas, we encourage anyone with leg symptoms or known cardiovascular risk factors to seek evaluation.

PAD as a Systemic Cardiovascular Warning Sign

One of the most important things to understand about peripheral arterial disease is that it rarely exists in isolation. The atherosclerosis that narrows the arteries in your legs is the same disease process that narrows the coronary arteries of the heart and the carotid arteries supplying the brain. Studies consistently show that patients with symptomatic PAD face a two-to-six times higher risk of cardiovascular events — including heart attack and stroke — compared to the general population.

This means that treating PAD at Minimally Invasive Specialists of Texas goes beyond restoring blood flow to the legs. Our team takes a whole-patient vascular health approach, working collaboratively with your cardiologist, primary care physician, and other specialists to ensure that your overall cardiovascular risk is being actively managed alongside your peripheral arterial treatment. If you have been diagnosed with PAD — or if you have significant cardiovascular risk factors — contact Minimally Invasive Specialists of Texas at (832) 583-2246 - Pasadena Office , (832) 583-2246 - Baytown Office or (832) 583-2246 - Clear Lake Office for a comprehensive vascular evaluation in .

Diagnosing PAD: What to Expect at Minimally Invasive Specialists of Texas

Early and accurate diagnosis of PAD is essential to initiating timely treatment before the disease progresses to limb-threatening stages. At Minimally Invasive Specialists of Texas, our diagnostic evaluation may include:

• Ankle-Brachial Index (ABI) Testing: The cornerstone non-invasive test for PAD. By comparing blood pressure measured at the ankle to that at the arm, an ABI calculation can reliably detect reduced arterial flow to the legs. An ABI below 0.9 is diagnostic of PAD; values below 0.4 indicate severe, limb-threatening disease.
• Duplex Vascular Ultrasound: Our team performs comprehensive vascular ultrasound imaging to visualize the leg arteries, measure blood flow velocities, and pinpoint the location and severity of stenosis or occlusion — without radiation or contrast dye.
• CT Angiography (CTA): A high-resolution imaging study that provides detailed anatomic mapping of the entire arterial tree from the aorta to the foot, using intravenous contrast under CT guidance. CTA is a critical planning tool before endovascular intervention.
• MR Angiography (MRA): An alternative to CTA using magnetic resonance technology, particularly valuable for patients with contrast allergies or kidney dysfunction.
• Catheter-Based Diagnostic Angiography: The gold standard for arterial imaging, performed by our interventional radiologists when endovascular treatment is planned. A catheter is guided into the arterial system under fluoroscopic imaging to provide real-time visualization of the diseased vessels — often followed immediately by treatment in the same session.
• Exercise ABI / Treadmill Testing: For patients with borderline resting ABI results, measuring the ABI after a brief period of walking can unmask PAD that is not apparent at rest.

Minimally Invasive PAD Treatment at Minimally Invasive Specialists of Texas

The goal of PAD treatment at Minimally Invasive Specialists of Texas is to restore adequate blood flow to the affected limb, relieve symptoms, heal wounds, and protect against limb loss — using the least invasive approach possible. Our treatment options include:

• Risk Factor Modification: Addressing the underlying drivers of atherosclerosis — smoking cessation, blood pressure optimization, cholesterol management, and diabetes control — is the most important foundation of long-term PAD management. These measures slow disease progression and reduce cardiovascular risk significantly.
• Supervised Exercise Therapy: A structured, medically supervised walking program is one of the most effective evidence-based treatments for claudication, capable of doubling walking distance and significantly improving quality of life over the course of several weeks to months.
• Antiplatelet and Statin Therapy: Aspirin or clopidogrel reduce the risk of arterial clotting and cardiovascular events. Statin medications lower cholesterol and stabilize existing arterial plaques, slowing PAD progression.
• Percutaneous Transluminal Angioplasty (Balloon Angioplasty): A catheter-based procedure in which a balloon is guided to the site of arterial narrowing under fluoroscopic imaging and inflated to compress the plaque and widen the vessel lumen. Angioplasty restores blood flow without surgical incisions and is performed under local anesthesia with conscious sedation on an outpatient basis.
• Arterial Stenting: When angioplasty alone is insufficient to maintain vessel patency, a metal stent is deployed within the treated artery to hold it open permanently. Stenting is particularly effective for disease in the iliac arteries (the large vessels supplying the legs from the pelvis), where long-term patency rates are excellent.
• Atherectomy: A catheter-based technique in which a specialized device is used to physically remove or vaporize calcified plaque from within the artery. Atherectomy is used in select cases where heavily calcified lesions are not responsive to balloon dilation alone.
• Drug-Coated Balloons and Drug-Eluting Stents: Advanced devices that deliver anti-proliferative medications directly to the arterial wall during the procedure, reducing the risk of re-narrowing (restenosis) and improving long-term outcomes — particularly in the femoropopliteal (thigh) arteries.
• Thrombolysis for Acute Arterial Occlusion: When a sudden arterial blockage occurs due to a blood clot — causing acute limb ischemia — catheter-directed delivery of clot-dissolving medication can rapidly restore blood flow and prevent irreversible tissue damage. This is a time-sensitive emergency intervention. If you experience sudden severe leg pain, pallor, or inability to move the leg, call 911 immediately.

Our team at Minimally Invasive Specialists of Texas collaborates closely with vascular surgery when bypass or more complex open procedures are needed. We also manage related conditions including deep venous thrombosis, chronic venous disease, and dialysis access management.

Limb Preservation: Treating Critical Limb Ischemia

Critical limb ischemia (CLI) is the most advanced and dangerous stage of PAD, in which blood flow to the lower leg and foot is so severely compromised that rest pain, non-healing wounds, and tissue death (gangrene) develop. CLI carries a serious risk of major amputation — up to 25% of CLI patients require amputation within one year without adequate revascularization.

At Minimally Invasive Specialists of Texas, limb preservation is a priority. Our interventional radiology team is experienced in complex below-the-knee angioplasty and tibial artery intervention — the technically demanding procedures required to open the small vessels of the lower leg and restore perfusion to the foot in CLI patients. Every day matters in CLI — early intervention dramatically improves the chances of saving the limb. If you or a loved one has a non-healing foot wound, rest pain, or blackened toes, contact Minimally Invasive Specialists of Texas immediately at (832) 583-2246 - Pasadena Office , (832) 583-2246 - Baytown Office or (832) 583-2246 - Clear Lake Office for urgent evaluation in .
