kärlgrupper

Kärlgrupper, a term originating from Swedish, translates to "vessel groups" or "vascular groups." In a medical context, it refers to clusters or formations of blood vessels within the body. These groups can be normal anatomical structures, such as the arterial or venous networks supplying specific organs or tissues.

However, the term can also be used to describe abnormal collections of blood vessels that may arise due to various pathological conditions. These can include congenital malformations like arteriovenous malformations (AVMs), where arteries and veins are abnormally connected, or acquired conditions such as vascular tumors or inflammatory processes that lead to neovascularization, the formation of new blood vessels. The study of these groups is crucial for understanding blood flow dynamics, diagnosing and treating vascular diseases, and planning surgical interventions. Imaging techniques like angiography, CT angiography, and MRI angiography are often employed to visualize and characterize kärlgrupper.
