Granulasjonsvev

Granulasjonsvev is a vital component of the wound healing process. It is a temporary connective tissue that forms at the site of an injury as the body repairs damaged tissue. This newly formed tissue is characterized by its granular appearance, hence the name, which is due to the abundance of small, reddish blood vessels that are essential for supplying nutrients and oxygen to the healing area.

The formation of granulasjonsvev is a complex process involving several cellular and molecular events. It begins with inflammation, where immune cells like neutrophils and macrophages clear debris and fight infection. Following this, fibroblasts migrate into the wound bed and begin producing collagen, a structural protein that forms the framework of the new tissue. Angiogenesis, the formation of new blood vessels, also occurs concurrently, providing the necessary vascularization.

Granulasjonsvev is typically pink or red in color and has a moist, granular texture. Its presence indicates that the wound is progressing through the proliferative phase of healing. While essential for repair, excessive or unhealthy granulasjonsvev can sometimes lead to complications such as hypertrophic scarring or keloid formation. In certain situations, such as chronic wounds that fail to heal, the appearance of granulasjonsvev might be diminished or absent, signaling a stalled healing process. Understanding granulasjonsvev is crucial for healthcare professionals in assessing and managing wound healing effectively.
