Do hepatic venous malformations (hemangioma or cavernous hemangioma) need to be treated?
When the patient is asymptomatic, there is no need for treatment regardless of its size. However, potential risks such as bleeding exist particularly in liver hemangiomas that are large and located near the capsule or the capsule of the liver is involved. In these cases, excessive physical activities or potential trauma sources should be avoided. There are some reports describing the transcatheter embolization procedure for liver hemangiomas, but it is not advisable similar to other venous malformations. Although it has not been tested, percutaneous sclerotherapy may be a great treatment alternative to surgical excision if treatment is needed.
