The Complications of the Varicose Veins
We call Type 4 or CVD - Complicated Venous Disease all of the situations where complications have already happened. The most frequent complications are Trombophebitis, the Leg Ulcers, Hyper-pigmentations , the Venous Eczema, the Bleeding, Fibrosis, the Ocre Dermatitis, the Infections, the Pain, and the Clot of Lung. They are usually patients who have had this problem for a very long time.
All these types follow an evolution, but it does not mean that one type will necessarily evolute to the other. The varicose veins always get worse, but each patient will have a different history and it doesn't mean, although it is possible, that the type 1 will turn into type 4.
The blood should flow inside of the vases, without interruptions. However, when a bleeding happens as in an accident or caused by some disease, or even a controlled bleeding as the ones of any surgery, the body tries to protect itself and control this situation that causes a risk of death. The most important is the coagulation system. The coagulation then is a good thing, when it happens for protection. But in certain situations this coagulation system can malfunction and cause serious problems.
When a vein has sick walls, as in the varicose veins, or if the system that makes the blood flow, the venous pump of the calf is working poorly, as in forced rests because of diseases or in long trips, the Venous Thrombosis can happen.
The Venous Thrombosis can be superficial or deep. The superficial happens in the vases of the surface of the member and the deep in the internal vases of the leg .
The venous thrombosis can have several causes, and among them, the Varicose Veins. When the coagulation of the blood inside the superficial veins happens, it is called Superficial Trombophlebitis.
When the veins of the members are extensive, as in the varicose veins, the whole process of flow of the blood is in jeopardy. We can say, in a simple way, that when the blood doesn't have a good flow in vein, it tends to coagulate, forming a clot (the thrombus) inside the vein. The superficial thrombophlebitis is one of the complications of the varicose veins. A coagulation inside the vase happens, interrupting the circulation as if it was a cork.
The patient complains about pain, redness and swelling in the varicose veins. The Superficial Venous Thrombosis has an effective treatment, but the great problem is that, although rarely, the clot can progress through the superficial veins to the deep veins. It can also, starting from the deep veins or through great superficial veins, release small pieces of coagulated blood, the embolus.
The embolus can, through the circulation, reach the lung. It stops there, impeding the circulation to happen and putting the life in risk. The progression of a Thrombus to the lung is called the Clot of Lung or Pulmonary Embolism.
Deep Venous Thrombosis
The Deep Venous Thrombosis, or DVT, is a fearsome occurrence, because it puts in risk the patient's life. Several are its causes, and one of them is the presence of Varicose Veins of Lower Extremities. It is a serious disease that is characterized by the formation of clots inside the deep veins of the leg. One of its main consequences in a short term is the Clot of Lung which can lead to death, prolong or complicate hospitalization after a surgery or even make the individual disabled for certain social activities and work, when it causes sequelae.
The pos-phlebitic syndrome can happen some years after DVT. It is characterized by swelling, dark coloration and hardening of the skin, eczema (chronic allergy of the skin) and ulcers (wounds) due to the alterations and scars left by DVT in the venous system. Certain people have risk factors for this disease. There are certain situations that can cause the disease; they are the risk situations. The individual factors and risk situations can characterize the patient as being in the risk group for the development of the disease. This risk is called Thromboembolic Risk .
We can mention as main individual risk factors for DVT, besides the varicose veins: people older than 40 years old, obesity, individuals who have already had thrombosis, the use of contraceptives and therapy of hormonal replacement, neoplasy, pregnancy and puerperal period, individuals with genetic abnormality of the coagulation system, traumatisms, surgeries, immobilization for long periods, hospitalization, diseases of the heart or lungs, and serious infections.
The Lung Clots happens when a piece of the clot that was formed inside the deep veins of the leg is released and reaches the blood vessels of the lungs. Depending on the size of the clot, the person cannot survive. In the case of varicose veins, although it can happen, the Pulmonary Embolism is a rare occurrence.
The difficulty that the blood has to return to the heart in the cases of varicose veins, ends up in stasis and swelling . The swelling and stasis cause a series of alterations in the lower extremities, mainly in the more distal part. The migration to the skin of elements of the blood happens, and they stay in places where they should not be. The presence of iron, derived of the hemoglobin of the blood, gives the skin of the leg or the ankle a dark and rusty aspect, called "Dermatitis Ocre."
Blood stasis also causes the inflammation of the skin, resulting in a venous eczema. The skin itches, peels and swells. It is an unpleasant and inconvenient problem caused by the varicose veins.
It is a difficult to control complication of the varicose veins. Furthermore, it is an unpleasant condition. The Venous Ulcer appears after a long evolution of the varicose veins. It is a wound, that can have a great extension, reaching a great part of the individual's leg.
The Bleeding is a serious complication that happens when the varicose vein increases so much of size, that breaks the skin that recovers the vein and perforates it, causing a profuse bleeding.
It is a sign of venous stasis. The individual's lower extremities are swollen, mainly in the end of the day.
Usually the patients with varicose veins complain about pain in the lower extremities associated with the weight and fatigue sensation that gets worse with the heat. Other factors may cause pain, such as sitting or standing for very long periods of time during the day, being, therefore, more intense in the end of the afternoon. In the women those uncomfortable symptoms tend to get worse in the premenstrual period and pregnancy. Associated with these symptoms, people usually complain about itching, tingling, heat, cramps, and the swelling of the ankles and lower extremities. These symptoms are proportional to the amount of varicose veins.
The order in which the complications appear
In a large number of patients, the varicose veins can be present for many years without complications, but the treatment should not be postponed, because the complications can take many years to appear, When they finally appear in a more advanced age, the effective treatment cannot be established anymore.
In the beginning of the evolution of the Varicose Veins of lower extremities, it is observed the weight sensation or fatigue in the end of the day. The visible varicose veins of several sizes appear slowly. The edema begins to appear in the end of the day. After there is the pigmentation (dermatitis ocre) and eczemas may appear. In evolution of the disease, Trombophlebitis, ulcers and bleeding may occur .
