Using infrared thermal imaging to evaluate angioplasty for peripheral artery disease
Infrared Thermal Imaging in Evaluating the Percutaneous Transluminal Angioplasty for Peripheral Artery Disease
This study is testing if infrared thermal imaging can help doctors see how well blood is flowing in the feet of patients with peripheral artery disease after they have angioplasty.

What this trial studies
This study evaluates the effectiveness of infrared thermal imaging (IRTI) in assessing blood perfusion in patients with peripheral artery disease (PAD) after undergoing percutaneous transluminal angioplasty (PTA). It aims to determine the success rate of the angioplasty procedure by monitoring changes in foot blood flow. The study focuses on patients with critical limb ischemia and varying degrees of arterial lesions, using IRTI as a follow-up tool post-surgery.
Who should consider this trial
Good fit: Ideal candidates include patients with Rutherford grades 3 to 6 who require PTA for severe claudication, rest pain, ulceration, or gangrene in one limb.
Not a fit: Patients with acute limb ischemia, those requiring major amputations, or those with indications for open surgery may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could provide a non-invasive method to assess the effectiveness of angioplasty in improving blood flow for PAD patients.
How similar studies have performed: While the use of infrared thermal imaging in this specific context is novel, similar imaging techniques have shown promise in evaluating vascular conditions in other studies.
