Which type of compression has been shown to decrease the risk of ulcer recurrence?

Class 2 (30-40 mmHg) compression therapy has been shown to be effective in decreasing the risk of ulcer recurrence. This level of compression is sufficient to provide adequate support to the venous system, improving venous return and reducing venous hypertension. Research indicates that this specific range of compression not only aids in healing existing ulcers but also plays a critical role in preventing new ulcers from developing.

The effectiveness of this compression class is attributed to its ability to enhance the calf muscle pump function, which is essential for promoting venous blood flow back to the heart. In contrast to other levels of compression, Class 2 offers a balance between efficacy and comfort for most patients, making it a standard recommendation in clinical practice for individuals at risk of ulcer recurrence.

Lower levels of compression, such as Class 1, may not provide sufficient pressure to effectively manage venous insufficiency or prevent recurrences. Higher levels such as Class 3, while effective for certain patients, may not be necessary or comfortable for everyone and can sometimes lead to complications if not tailored to individual patient needs. Hence, Class 2 compression stands out as the optimal choice based on current evidence.
