About this study

Official title: Multi-Center Registry Comparing Stent and Non-Stent Based Interventional Outcomes for Patients With Peripheral Arterial Disease

XLPAD is an observational study designed to evaluate the effectiveness and use of stent and non-stent based therapies among PAD patients. The study will create a registry that will include entry of procedural and clinical follow-up information into an online data collection software, REDCAP.Data available since Jan 1 2005 will be included in the registry, until 14,000 patients have been included. The primary objectives of this observational registry study are to:

  1. Compare stent and non-stent based outcomes defined as a composite of symptom driven target vessel revascularization (TVR), unplanned surgical revascularization of the target limb and need for target limb amputation through 12 months post-index procedure (Primary efficacy endpoint)
  2. Compare stent and non-stent based outcomes defined as a composite of causes such as: death, myocardial infarction (MI), stroke, peri-procedural complications, target vessel revascularization (TVR) and unplanned surgical revascularization/amputation of the target limb through 12 months (Primary safety endpoint)
  3. Compare stent and non-stent based change in walking distance, Rutherford category and/or ankle- brachial index (ABI) at 12 months compared to baseline (Primary clinical improvement endpoint)

Approximately 14,000patients will be enrolled at approximately 60 sites worldwide. Enrollment in the observational study will be monitored in an effort to achieve at least 20% (and no more than 80%) of the population receiving stents as the initial treatment strategy. Follow-up visits by sites will be reported at 6 and 12 months after index procedure to collect data on treatment patterns and effectiveness, and outcomes. The follow-up procedures are not mandated by the registry protocol. Each site will be encouraged to enter follow-up information derived from clinically indicated follow-up visits. All events post-index procedure till the 7th month will be reported under the 6 month follow-up form and subsequent follow-up till the 13th month post-procedure will be entered on the 12 month follow-up form.

Patient management and treatment decisions are at the discretion of the care team per routine clinical practice. The procedural aspects (including selection of stent type or non-stent based treatments) and follow-up are not mandated by the registry and will be up to the discretion of the operator and/or based upon the practice dictated by the clinical care of the patient. Therefore the study poses minimal risk to the patient.

Read the detailed description

Patients undergoing an endovascular intervention receiving either stents or percutaneous transluminal angioplasty (PTA) to the superficial femoral, popliteal, peroneal, anterior tibial, or posterior tibial arteries will be entered into this registry. Patients undergoing treatment of the external or common iliac arteries are not admissible to the registry, unless these arteries were treated in addition to one of the five aforementioned arteries. The registry will collect data in the form of patient background information, procedural data, and follow-up data from the patient's medical records. Data available since Jan 1 2005 will be included in the registry, until 14,000 patients have been included. The data will be entered into a software, REDCAP, that automatically provides data quality verification and processing.

Specifically, the data fields collected by the registry will be:

  1. Background Information
  2. Site, attending operator, and month-year of procedure
  3. Patient height, weight, age, race, and sex
  4. Rutherford claudication category, left and right ankle brachial index, ambulatory status, claudication free distance
  5. Risk factors such as diabetes, hypertension, hyperlipidemia, and prior history of lower extremity percutaneous intervention
  6. Patient comorbidities such as coronary artery disease, congestive heart failure, prior myocardial infarction, stroke, transient ischemic attack, chronic kidney disease, and other.

II) Lesion Characteristics (enter data for up to five lesions)

  1. Access site relative to target limb, sheath size, target limb (left or right)
  2. Target vessel: superficial femoral artery, popliteal artery, peroneal artery, anterior tibial artery, or posterior tibial artery
  3. Which, if any, Iliac arteries were treated during procedure
  4. Target lesion location (ostial, proximal, medial, distal), estimated vessel diameter, estimated vessel length
  5. Lesion characteristics (heavily calcified, diffuse, thrombus, chronic total occlusion (CTO), in-stent restenosis, restenosis post balloon angioplasty, profunda femoris disease)
  6. Planned revascularization strategy: stent or non-stent based

IIa) CTO Characteristics (Only required for CTO lesions)

  1. Type of proximal and distal stumps, sidebranches present, collateral filling of distal vessel, tortuosity, prior attempt to cross CTO
  2. Antegrade or retrograde crossing strategy, crossing technique, number of attempts
  3. Crossing devices used, microcatheters used, sub-intimal re-entry devices used (if any), embolic protection device used

III) Intervention Details

  1. Atherectomy device used (Cutting Balloon, TurboHawk, SilverHawk, Rotablator, Laser)
  2. Pre and post-dilation balloon information (type, length, width, average atmospheric pressure, number of inflations)
  3. Stent information (indication for stents, length, width, maximum pressure, overlapping with previous stents)
  4. Aspiration/Thrombectomy used, thrombolytic therapy used
  5. Percent change in stenosis and TIMI flows (before and after)

IV) Outcomes

  1. Technical success (<30% residual stenosis), procedural success (<30% residual stenosis without complications), and case comments
  2. Anti-coagulation used, medical therapy (plavix, aspirin, lipid lowering therapy, angiotensin receptor blocker, beta blocker, cilostazol, trental, insulin, oral hypoglycemics)
  3. Duration of procedure, fluoroscopy (amount used, type, and time)
  4. Any procedural complications
  5. Follow-Up
  6. Month and year of follow-up
  7. Rutherford category, left and right ankle brachial index, claudication-free distance, ambulatory status, change in claudication (improved, same, or worsened)
  8. Duplex ultrasound performed
  9. Adverse events experienced (death, myocardial infarction, stroke, stent thrombosis, stent fracture, angiography, repeat endovascular intervention, surgical revascularization, amputation in target or non-target limb)

Follow-up data is recorded from clinical visits six and twelve months after the procedure. If the patient undergoes a repeat intervention on the target limb, a new record is created for the procedure.

Questions about this trial

What is this clinical trial studying?

An observational study of Peripheral Arterial Disease, run by Baylor Research Institute at 24 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

How can a doctor refer a patient or contact the research team?

Contact David Fernandez Vazquez, MD (2148202928, david.fernandezvazquez@bswhealth.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Target Limb Revascularization (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01904851, which also lists 9 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2026.
