Thermography in lower limb arterial disease

Area of Science:

• Medical Imaging
• Physiology
• Vascular Medicine

Background:

• Arterial obstruction in lower limbs significantly impacts blood flow.
• Assessing the severity of this obstruction is crucial for effective treatment.
• Non-invasive methods for evaluating lower limb vascularity are highly desirable.

Purpose of the Study:

• To investigate the relationship between skin temperature distributions and arterial obstruction levels in the lower limbs.
• To evaluate the utility of thermography in assessing blood flow impairment.
• To correlate exercise-induced skin temperature changes with the degree of vascular compromise.

Main Methods:

• Utilized thermography to capture skin temperature distributions.
• Measured changes in skin temperature during limb work (exercise).
• Correlated thermographic data with established indicators of arterial obstruction and blood flow impairment.

Main Results:

• Distinct skin temperature patterns were observed corresponding to varying degrees of arterial obstruction.
• Thermography effectively detected changes in skin temperature during limb exertion.
• A significant correlation was found between exercise-induced skin temperature changes and impaired lower limb blood flow.

Conclusions:

• Thermography is a valuable, non-invasive tool for assessing lower limb arterial obstruction.
• Exercise thermography can quantify functional impairment related to vascular compromise.
• This technique offers a promising method for clinical evaluation of peripheral artery disease.
