Congestive splenomegaly occurs when the portal or splenic vein (main veins of the spleen) becomes blocked.4 Certain drugs, such as barbiturates, can increase blood pooling and, therefore, cause a slight "back up" of blood to the spleen.3 Affected patients may have a decreased PCV because the blood cannot filter properly.3 Right-sided congestive heart failure, obstruction of the caudal vena cava (such as with heartworm disease), and splenic torsion can all cause congestive splenomegaly.3
