Venous Pathology

Functional anatomy

Larger veins have a simailar archiecture to arteries, though thinner walled. Venules have no muscular layer. The intimal layer has no internal elastic lamina. The main distinguishing feature of veins is their posession of valves.

Obstruction of the venous circulation creates high pressure in the capillary beds surrounding the affected area. As a result, edema and/or effusion are very common clinical signs seen in these types of diseases. Some specific examples of venous diseases are detailed below including Budd-Chari-Like syndrome, Portal Vein Thrombosis, and Cranial Vena Cava Syndrome.
