What is the diagnostic approach for chronic venous insufficiency (CVI)?

From the Guidelines

The diagnostic approach for chronic venous insufficiency (CVI) should begin with a thorough clinical history and physical examination, followed by duplex ultrasound as the gold standard diagnostic test, as recommended by the most recent study 1 from 2023. The CEAP classification system (Clinical-Etiology-Anatomy-Pathophysiology) should be used to categorize disease severity, ranging from C0 (no visible signs) to C6 (active venous ulcers) 1. Some key points to consider in the diagnostic approach include:

• Focusing on risk factors and characteristic symptoms such as leg heaviness, pain, edema, and skin changes
• Using duplex ultrasound to provide information about venous reflux, obstruction, and anatomical abnormalities without radiation or contrast exposure
• Considering additional diagnostic tools such as the venous clinical severity score (VCSS) to quantify disease severity and plethysmography to assess venous function
• Using advanced imaging such as CT venography or MR venography in complex cases to evaluate deep venous structures or plan interventions
• Measuring the ankle-brachial index (ABI) to exclude arterial disease, particularly before compression therapy is initiated, as suggested by 1 and 1. Early and accurate diagnosis is crucial as CVI is progressive, and timely intervention can prevent complications like venous ulcers and improve quality of life, highlighting the importance of a thorough diagnostic approach 1.

From the Research

Diagnostic Approach for Chronic Venous Insufficiency (CVI)

The diagnostic approach for CVI involves a combination of patient history, physical examination, and diagnostic tests.

• A careful medical history and physical examination are essential in assessing the nature of the patient's underlying venous disease 2.
• Bedside diagnostic tests, such as duplex ultrasonography, can be used to confirm the diagnosis of CVI 3, 2.
• Additional diagnostic tests, including venography, plethysmography, and ambulatory venous pressure measurement, may be necessary to assess the severity of the disease 2.
• The CEAP classification system can be used to describe chronic venous disorders regarding clinical appearance, etiology, anatomical distribution, and pathophysiology 4.

Classification and Treatment

• The classification of CVI is based on the results of the diagnostic tests and is used to select an appropriate treatment strategy 2.
• Treatment options for CVI include conservative management, such as compression therapy and exercise programs, as well as interventional therapies, such as sclerotherapy and endovenous laser ablation 3, 5, 6.
• The choice of treatment depends on the severity of the disease and the patient's individual needs 4.
• Hybrid methods, such as combining endovenous laser therapy with echosclerotherapy, have been shown to be effective in treating CVI 6.

Diagnostic Tests

• Duplex ultrasonography is a non-invasive test that uses sound waves to create images of the veins and can be used to diagnose CVI 3, 2.
• Venography is an invasive test that involves injecting a contrast agent into the veins to visualize them on an X-ray 2.
• Plethysmography is a non-invasive test that measures the volume of blood in the legs and can be used to assess venous function 2.
• Ambulatory venous pressure measurement is a test that measures the pressure in the veins while the patient is walking 2.
