Study to Find Out the Timing for the Optimal Imaging of Varicose Veins Using Infrared Thermography.

Recruiting now

Conditions studied: Varicose Veins Leg

In brief

The goal of this observational study is to identify the optimal time of Infrared imaging of varicose veins when patients move from a lying to a standing position. The primary purpose is to enable us to improve our imaging of varicose veins in patients presenting with primary or recurrent leg varicose veins. The main questions it aims to answer are: Outcome measure 1- How long after standing up from lying supine do leg varicose veins show up best on infrared imaging? Outcome measure 2 - Is there any difference in this timing between varicose veins arising from different sources in the leg? Patients will be asked to stand, and sequential infrared images will be taken every 5 seconds for 3 minutes.
