What is the main purpose of performing a venous insufficiency study?

The main purpose of performing a venous insufficiency study is to evaluate the competence of venous valves. This type of study focuses on assessing how well the valves in the veins are functioning, determining whether they are allowing for the proper one-way flow of blood back to the heart. When venous valves are incompetent, blood can flow backwards (reflux), leading to venous insufficiency which may cause symptoms like leg swelling, pain, and varicose veins. This study can provide crucial insights into venous health and guide clinical decisions regarding treatment options for patients experiencing symptoms related to venous insufficiency.

In contrast, assessing arterial blood flow is more relevant to arterial studies, and while detecting deep vein thrombosis (DVT) is important, it is a separate diagnostic focus typically involving other imaging techniques. Measuring oxygen saturation pertains primarily to analyzing arterial blood gas and is not the objective of a venous insufficiency study. Thus, evaluating venous valve competence is central to diagnosing and managing conditions related to venous insufficiency.
