About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients undergoing venous duplex ultrasound scan for suspected varicose veins (primary or recurrent).
Able to stand still for 5 minutes.
Able to get on to and off of the surgical couch unaided.
Patient giving consent.
Disqualifiers
Refusing consent.
Unable to get on a couch or stand unaided.
Unable to stand still for 5 minutes.

Trial outcomes
Primary outcomes
1
Time of optimal Infrared imaging of leg varicose veins after standing from lying
Sequential infrared images will show us at what time point the optimal infrared images have been obtained.
Time frame
The whole process for the patient will be a maximum of 20 minutes. The analysis of all of the images will be completed within 1 month of the end of the data collection.Secondary outcomes
1
Variation of optimal infrared image timing due to the source of venous reflux
Using the infrared images and comparing them with the duplex ultrasound scans that the patient is having as part of their normal medical assessment, we will subdivide the images by the underlying source of the varicose veins and venous reflux. We will assess whether there is a different time to optimal Infrared imaging with different patterns of venous reflux, predominantly great or small saphenous reflux.
Time frame
The patient data collection will be within 20 minutes, and the analysis within 1 month.Sponsors and contacts
