[Myeloproliferative diseases as causative agents of portal and hepatic veins thrombosis].
Thrombosis of portal and hepatic veins is one of the most severe complications and most important causes of death of patients with chronic myeloproliferative diseases. Based on results of the past studies, myeloproliferative diseases were the causes of hepatic veins thrombosis in 30% and portal vein thrombosis in 20% of patients. The study presented 4 patients with myeloproliferative diseases complicated by thrombosis of splanchnic veins, aiming at the illustration of issue complexity in diagnostics and therapy. Two patients with portal vein thrombosis and recurring hemorrhage from esophageal varicosity were described. The first case was planned for shunting, while another case sustained bleeding on what account his anticoagulant therapy was discontinued, but it caused mesenterial thrombosis resulting in lethal outcome. Another two patients had hepatic veins thrombosis. Due to frequent, life-threatening bleeding from the esophageal and gastric varices, a patient with chronic Budd-Chiari syndrome and lineal vein thrombosis underwent mesocaval shunting. An immediate postoperative period was manifested by multiple thrombosis and hemorrhages that ended in his death. A patient with the acute Budd-Chiari syndrome was administered myelosuppressants and anticoagulants on time so reperfusion was restored. In myeloproliferative diseases, thrombosis of portal and hepatic veins gives rise to excessive portal hypertension with profuse hemorrhage from the esophageal and gastric varicosity which is difficult to manage because of complex coagulation disorders.
