Hello Lisa,

Thank you for asking your query at DoctorSpring.

Arterial and Venous vascular 'disorders' is a broad term.

As you might be well aware, in the circulatory system there are arteries which carry the oxygenated blood and the veins which carry the deoxygenated blood. Arteries and Veins , although they carry both blood the types of diseases / disorders are different in both. This is because.

1. The structural difference
2. The difference in the function or functional capacity.

Let's see the major ones

Venous Disorders :

1.Venous Insufficiency
2.Varicose Veins
3.Deep Vein thrombosis
4.Thrombophlebitis
5.Venous Ulcer

Arterial Disorders :

1.Peripheral Vascular Diseases like TAO
2.Atherosclerosis
3.Peripheral Vein Thrombosis
4.Vasculitis / Arteritis
5. Aneurysms
6.Arterial ulcer.

Even though both are "tubes that carry blood", you can see that the disorders affecting them are different. Even the few similar disorders like Thrombosis and Ulcer have different mechanisms and clinical presentation . Please see these links for more information
