- Venous ulcer
Vein insufficiency can lead to more serious problems over time. As leg pressure increases throughout the day, the vein diameter gradually increases. It dilates the vein and tries to balance the increased pressure. Over time, this situation gradually increases and fluid begins to leak out of the veins and leg swelling occurs.
Swelling can also be seen as a permanent scar caused by the accumulation of fluid, whose volume has increased in chronic venous insufficiency, in the skin and subcutaneous tissues and the protein that precipitates in these parts over time. . This form of edema that occurs in patients usually first starts on the back of the foot and can progress over time to the ankles, lower legs, and lower and upper knees.
Skin shape and color changes can occur in the entire leg, but generally the ankles are affected. It is more common just above, inside and in the front. Due to venous disease, the increased venous pressure just above the front of the ankle causes blood to leak out of the vein. As a result of this leakage, red cells from the shaped elements of the blood come out of the vessel. After completing their lives outside the vein in this region, they die and the oxygen-carrying substance of the blood, which we call hemoglobin, is released outside the vein.
The organism breaks down this hemoglobin into heme and globin. Globin is sent to the necessary places to be used in newly produced blood cells. “Hem” meaning the iron stays there. Dark color changes and subsequent varicose ulcers begin to form.
