Venous insufficiency is a widespread condition affecting millions of people worldwide. It can involve either superficial or deep veins, and distinguishing between these forms is essential for accurate diagnosis and treatment. Precision in diagnosis is key: the Venous Function Test is an indispensable tool for differentiating between superficial and deep insufficiency. Thanks to modern technologies, such as the devices from SOT Medical Systems, this differentiation becomes efficient, reliable, and practical for everyday clinical use—a crucial step towards optimal treatment strategies.
Why is Differentiation Important?
Distinguishing between superficial and deep venous insufficiency is critical for determining the appropriate therapy. Superficial insufficiencies, such as varicose veins, can often be treated with minimally invasive methods. In contrast, deep insufficiencies affect the major veins of the leg and can lead to severe complications such as venous ulcers. The Venous Function Test provides the data needed to accurately diagnose these conditions and develop tailored treatment plans.
The Role of the Venous Function Test
The Venous Function Test is a non-invasive diagnostic procedure specifically designed to analyze venous function. This test allows physicians and medical staff to assess the efficiency of the venous pump function and the reflux time (refill time). Crucially, the test distinguishes between superficial and deep reflux, which significantly influences therapy planning.
The Measurement Principle: Light Reflection Rheography (LRR)
The Venous Function Test is based on Light Reflection Rheography (LRR), a non-invasive technique that measures blood flow in the veins. This method analyzes changes in blood volume by measuring light reflection on the skin’s surface. LRR is particularly precise and provides a detailed analysis of venous function.
Two Key Parameters: V0 and T0
V0 – Venous Pump Volume:
This parameter measures the volume of blood pumped out of the veins during a muscle contraction. A low V0 indicates inefficient muscle pump function, often associated with deep insufficiency.
Example: A patient with a V0 below 3% may exhibit poor venous pump function.
T0 – Venous Refill Time:
T0 measures the time required for veins to refill after a contraction. A short T0 indicates venous reflux, where blood flows back faster than normal, potentially due to valve insufficiency.
Example: A T0 of less than 25 seconds may suggest superficial or combined insufficiency, requiring further differentiation.
