| − | ==Developmental pathology== | + | '''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. |
