A Multidisciplinary Treatment Approach

Specialized team providing success through collaboration.

Center of Excellence in Peripheral Artery Disease

Peripheral artery disease (also called peripheral arterial disease) is a common circulatory problem in which narrowed arteries reduce blood flow to the limbs. This condition is a prevalent and underdiagnosed disease in West Texas and can cause many symptoms ranging from mild claudication to ischemic necrosis and subsequent limb amputation. The study of PAD is an important area of research in cardiology as there is relatively little information on the outcomes of PAD treatment.

The Center of Excellence in Peripheral Artery Disease (PAD) Treatment at Texas Tech University Health Sciences Center is focused on providing successful screening, treatment, and education of PAD through collaborative efforts of multidisciplinary clinicians at Texas Tech Physicians.

Our mission is to coordinate a multidisciplinary treatment approach for patients diagnosed with PAD. Our team of specialists includes:

• Interventional cardiologists who specialize in peripheral endovascular
   intervention as well as vascular surgeons

• Imaging cardiologists
• Wound care specialists
• Podiatrists

Additionally, our team includes specialists who cover additional risk factors, such as endocrinologists, rheumatologists, orthopedics, and nephrologists. 


Screening and Diagnostic Modalities

• Screening test at TTUHSC CCVH
• ABI/TBI and Ultrasound-UMC Ultrasound Lab
• CT Scan and MRI-UMC Radiology
• Lower extremity angiograms: UMC Cath lab

Treatment Modalities

• PAD-CLI (CLTI) program includes all kinds of endovascular and surgical procedures
  performed at TTUHSC-UMC

Endovascular procedures are performed at the UMC Cardiac Cath Lab which includes new techniques and device utilization, including wires and crossing catheters, balloons, stents, atherectomy devices, thrombectomy devices, and state of the art new technology through newer clinical research trials. The program is in collaboration with Vascular surgery, performed in UMC’s state of the art operating rooms. 

Strategic Goals

1. Collaborative Research 

• Expand the clinical research scope for various ongoing clinical research efforts and trials 

2. Patient Care 

• Collaboration with physicians across West Texas to improve PAD patient care

3. Education

• Increase research exposure education for patients
• Increase education for primary care providers
• Increase opportunities for medical students to obtain research experience
  during their medical curriculum
