Hypervascularity refers to a condition characterized by an abnormally increased number of blood vessels in a particular tissue or organ. This can manifest in various ways, from subtle increases in capillary density to the formation of larger, abnormal blood vessels. The underlying cause of hypervascularity is often related to the body's response to tissue injury, inflammation, or the growth of abnormal cells.

One of the most common associations with hypervascularity is tumor growth. Tumors require a rich blood supply to obtain oxygen and nutrients for their rapid proliferation. This process, known as angiogenesis, involves the development of new blood vessels from pre-existing ones. These tumor-associated blood vessels are often disorganized and leaky, contributing to the rapid growth and potential spread of the tumor.

Hypervascularity can also be observed in non-cancerous conditions. For example, inflammatory processes, such as those seen in rheumatoid arthritis or certain eye diseases, can trigger increased blood vessel formation to deliver immune cells and other repair factors to the affected area. Certain vascular malformations, like arteriovenous malformations (AVMs), also represent a form of hypervascularity where there is an abnormal connection between arteries and veins.

Diagnosing hypervascularity typically involves medical imaging techniques such as Doppler ultrasound, computed tomography (CT) angiography, or magnetic resonance imaging (MRI) with contrast agents. These methods can highlight areas with increased blood flow. Treatment strategies for hypervascularity depend on the underlying cause and can range from managing inflammation to more targeted therapies for tumors, including anti-angiogenic drugs that inhibit blood vessel formation.
