Which of the following is a type of low flow malformation?

Capillary malformations are indeed categorized as low flow malformations. These lesions are typically characterized by an abnormal development of capillaries, leading to a red or purple stain on the skin. They are often present at birth and are usually superficial, indicated by their flat appearance and they do not typically involve significant blood shunting or high pressure, differentiating them from high flow malformations.

In contrast, arteriovenous malformations involve a tangle of blood vessels connecting arteries and veins directly, leading to high flow and potential complications. High flow malformations, by definition, also represent conditions where there is increased blood flow and pressure. Hemangiomas, although a type of vascular tumor, may initially have low flow characteristics, they undergo a phase of rapid growth and can become more complex, thus placing them outside the strict definition of low flow malformations.

Therefore, among the choices given, the capillary malformation fits the definition of a low flow malformation the best, making it the correct answer.
