Common Causes And Complications Of A Port Wine Stain

Klippel-Trenaunay Syndrome

Klippel-Trenaunay syndrome is a genetic condition that produces changes in blood vessels, bones, and soft tissues such as muscles and skin. Patients with the syndrome typically have varicose veins, an abnormal overgrowth of both bones and soft tissues, and a port-wine stain that covers part of a limb. The overgrowth of bones and soft tissues usually impacts one of the patient's legs, but it may occasionally affect their arms. In rare instances, the torso could be impacted. The area impacted by the overgrowth could feel heavy and painful, and there is generally a reduction in the range of motion at the affected site. If a leg is affected, it could become more than two centimeters longer than the unaffected leg, and this might result in difficulties with walking. Doctors may recommend duplex scanning, MRI scans, and a scanogram to evaluate the blood vessels and bones. Surgery might be necessary to correct an overgrowth in a leg, and patients often benefit from laser therapy and epiphysiodesis.
