Patients with varicose veins show purple calves, which means that the condition is very serious and is caused by a long history of the disease and local lack of oxygen to the skin, and even in severe cases there is also necrosis of the skin and the formation of an obvious ulcerated surface. In severe cases of varicose veins, surgery is also an option, because a portion of the varicose veins can also form thrombotic emboli within the vein mass and localized sterile inflammation, which can lead to secondary infections and changes in skin color if left untreated for a long time. The surgery requires excision of the non-functioning vessels and stripping of the emboli to avoid serious complications due to the return of the emboli into the deep veins with the venous blood. The patient also needs to have regular checkups after the surgery and proper functional exercises, mainly to promote venous blood return to the lower extremities, by choosing foot dorsiflexion exercises and intermittent elevation of bilateral lower extremities.
