videokapillaroskopiaan

Videokapillaroskopia is a non-invasive diagnostic technique used to examine the small blood vessels, or capillaries, in the nail fold. This procedure involves using a specialized microscope, often coupled with a video camera, to visualize the capillaries under high magnification. The image is then displayed on a screen, allowing for detailed observation of the capillary morphology, blood flow, and surrounding tissue.

The primary purpose of videokapillaroskopia is to detect abnormalities in the capillaries that may indicate underlying systemic diseases. Conditions such as connective tissue diseases, particularly scleroderma, Raynaud's phenomenon, and various autoimmune disorders, often manifest with characteristic changes in nail fold capillaries. These changes can include dilation, tortuosity, or the presence of giant capillaries.

During the procedure, a small drop of immersion oil is typically applied to the nail fold to enhance visualization. The patient's hand or foot is then placed under the microscope. The examination is usually quick and painless. The captured video images or still photographs can be analyzed by a trained clinician to identify specific patterns and diagnose or monitor the progression of certain conditions. Videokapillaroskopia provides valuable insights into the microcirculation and can aid in early diagnosis and management of diseases affecting the vascular system.
