Anesthetic management of a parturient with congenital cavernous transformation of the portal vein and chronic thrombocytopenia.

Cavernous transformation of the portal vein is a rare disorder resulting from extrahepatic portal vein thrombosis and development of collateral venous circulation. We report a case of a pregnant patient with congenital cavernous transformation of the portal vein associated with persistent consumptive coagulopathy and chronic thrombocytopenia. Single dose spinal anesthesia was safely conducted for an uneventful cesarean delivery.
