Compare the pathophysiology of chronic venous insufficiency and deep venous thrombosis. Describe how venous thrombosis is different from arterial thrombosis.

Veins and arteries disorders

Pathophysiology for chronic venous (CVI) insufficiency and deep venous (DVT), both of which are caused by an obstruction to the flow of blood through the veins, is the same. This is caused by a degeneration or destruction of the walls in the veins, which decreases the ability of those vessels to transport blood towards the heart. It is usually caused by ageing, trauma, diabetes, hypertension and lifestyle factors such as smoking.

DVT, on the other hand occurs when a blood clot develops inside a deep vein in the body that blocks the normal flow of blood. This can be caused by many different conditions including genetic predisposition, injuries that cause vein damage or inflammation, surgery, pregnancy, certain medications/treatments (e.g. Even prolonged immobility or chemotherapy can lead to thrombosis. Venous and arterial thrombosis are different in the fact that they affect veins, not arteries. Both share risk factors like obesity and old age. Both types of thrombosis are serious and can lead to other health issues if they’re not properly treated. However, there are treatments that reduce the symptoms as well as prevent future complications.
