If blood loss occurs after splenic embolization, it can result in low platelets, but the platelet count usually increases some time after splenic embolization.
Splenic embolization reduces the phagocytosis and destruction of platelets by the spleen, so platelets generally increase 1 to 2 weeks after the procedure. The rate of platelet elevation after splenic embolization mainly depends on the supply of embolizing vessels, the size and location of the spleen. Therefore, there is usually no platelet drop after splenic embolization, unless the patient experiences blood loss after splenic embolization. Blood loss is not a common post-splenic embolization complication.
Splenic embolization refers to the use of embolic agents, such as gelatin sponge pellets and spring coils, to embolize the splenic artery in order to cause ischemic necrosis of a portion of the spleen, thus serving to abrogate splenic function, and is used to treat splenic enlargement and hypersplenism of various causes.
The most common causes of splenomegaly are cirrhosis and portal hypertension. Common complications after splenic embolization include fever, pain, and splenic abscess.
Patients who are in need of splenic embolization are advised to go to a regular hospital to avoid delays.
