Patient's question:
A strange thing has grown on the child's neck. It looks like a red patch, but there's no sensation of anything abnormal. A few days ago, I took my child to the hospital for a thorough examination. The doctor said it was a vascular malformation. I want to consult about the causes of vascular malformations. What are the causes of vascular malformations?Doctor's answer:
Causes of venous malformations 1. In the early embryonic stage (8-12 months), the embryo is exposed to mechanical injury, leading to local skin damage. This prompts some stem cells to migrate into other embryonic cells. A small portion of these cells divide to form vascular-like structures, which eventually develop into venous malformations. 2. During the growth and development of the human embryo, especially during the early stages of vascular splitting, small-scale mutations in the suppressor gene segments can cause abnormal splitting of vascular structures in specific areas, leading to their expansion into venous malformations.
