Stages Of Chronic Venous Insufficiency

Stages Of Chronic Venous Insufficiency

What is Chronic Venous Insufficiency? Is it correlated to varicose vein treatment? Also, have you heard about phlebitis? At USA Vein Clinic, let us assist you in understanding all the implications. 

What is Chronic Venous Insufficiency?

Chronic venous insufficiency (CVI) consists of the inability of blood from the veins to return to the heart after reaching the lower limbs, where it tends to stagnate.

It can originate from an alteration of the veins, the so-called organic chronic venous insufficiency, or it can be caused by hyperactivity of the veins themselves, the so-called functional Chronic Venous Insufficiency.


Chronic Venous Insufficiency can be caused by a dilation of the walls of the veins (varicose veins) which in turn can derive from various causes such as pregnancy, overweight, water retention and others.

Chronic venous insufficiency is prevalent, especially among women, so much so that it is estimated that 3 out of 10 females are affected to varying degrees in Italy.

Chronic functional venous insufficiency instead derives from an overload of work of the veins which incorrect postures, poor movement of the lower limbs or alterations of the muscle pump, can cause. 

Excess weight is an apparent risk factor for the onset and development of chronic venous insufficiency of the lower limbs.

This is because the obese tend first to move little, and their blood is pumped much more slowly due to the large number of fat cells in parts of the body affected by the flow of blood directed towards the lower limbs. On this note, we need to check for immediate agitation on varicose vein treatment.

What is Phlebitis?

Phlebitis is an inflammation particularly affecting the walls of the superficial veins of the legs. When the inflammation is linked to a blood clot, it is in the presence of thrombophlebitis.

When the lump is present in deep veins, especially in the leg and hip, a deep vein thrombosis can occur and cause an embolism, with the associated risk of death of the patient.

Phlebitis (or superficial vein thrombosis) is the inflammation of an external vein caused by a thrombus that can block the internal cavity and prevent blood from circulating properly.

The causes of thrombus formation can be different; in most cases, it is impossible to identify them with certainty. The most common reasons are obesity, trauma, an excessive sedentary lifestyle, immobility due to rest after surgery, and taking certain medicines.

Phlebitis mainly affects the legs (lower limbs), especially in people suffering from varicose veins; in some cases, it can also affect the veins in the neck, arms or any other body part.

The vein can be on the surface, and in this case, we spoke of superficial thrombophlebitis, or deep and located inside a muscle and, in this case, we spoke of deep vein thrombosis.

This much more difficult situation puts the person at risk of serious complications. It is therefore advised to see vein specialists for varicose vein treatment.

Phlebitis usually resolves within 2 to 6 weeks. In some cases, high fever, chest pain and difficulty breathing may occur.

In these cases, you must urgently go to the hospital emergency room because phlebitis could be accompanied by deep vein thrombosis. This severe disease exposes you to the risk of pulmonary embolism.


  • Prolonged immobility, for example, during long car journeys or plane rides
  • Permanence in bed for chronic diseases or following surgery
  • The trauma of the vein by external crushing or by insertion of a needle cannula or an intravenous catheter
  • People with cases of thrombophilia in the family
  • Women taking the contraceptive pill or hormone replacement drugs
  • Pregnant women
  • Patients with some cancers
