Chronic Venous Insufficiency

Question 1

A common condition typically involves lower extremity edema, trophic skin changes, and discomfort secondary to venous hypertension.

Answer 1

Chronic venous insufficiency

Question 2

The following three systems make up the lower extremities’ venous network, which CVI frequently impacts

Answer 2

1. Superficial Veins and the Small Saphenous Veins
2. Perforating Veins
3. Deep Veins (including the deep femoral, superficial femoral, peroneal, popliteal, anterior, posterior, and iliac veins)

Question 3

Either due to reflux (backward flow) or obstruction of
venous blood flow

Answer 3

Chronic venous insufficiency

Question 4

It is usually due to weakened or abnormally shaped valves or widened venous diameter, which prevents normal valve congruence

Answer 4

Superficial incompetence

Question 5

It is usually owing to the previous DVT, which results in inflammation, valve scarring and adhesion, and luminal narrowing.

Answer 5

Deep vein dysfunction

Question 6

It allows higher pressure to enter the superficial venous system. The subsequent dilation prevents the proper closure of the valve cusps in the superficial veins

Answer 6

Perforating vein valvular failure
