Venous malformations—tissues made up largely of abnormally shaped veins—are often difficult to treat, especially when located in sensitive areas like the eyes, face, and genitourinary organs. In the worst cases, the lesions are disfiguring and can crush or obstruct surrounding tissues, cause bleeding and clotting, interfere with breathing or vision, or impair circulation.
