What is a key characteristic of chronic venous insufficiency?

Chronic venous insufficiency is a condition characterized by the failure of the venous system of the legs to adequately return blood to the heart, primarily due to malformations or dysfunctions of the valves within the veins. This malfunction leads to increased venous pressure and can result in pooling of blood, ultimately causing symptoms such as varicose veins, edema, and other complications.

Malformations of the valves and obstruction play a significant role in the development of chronic venous insufficiency. When the valves do not close properly, blood can flow backward and accumulate in the veins, leading to symptoms associated with this condition. Additionally, obstruction in the venous system may further exacerbate these problems by inhibiting proper blood flow.

Understanding the pathophysiology of chronic venous insufficiency emphasizes the importance of valve function in maintaining venous return. This knowledge is crucial for professionals in the field of phlebology, as it informs diagnosis and treatment strategies.
