title: [The effect of internal jugular vein ligation on cerebral circulation in children with extrahepatic portal hypertension].
abstract: The menesterico-caval H-bypass using right internal jugular vein was performed in 63 children with extrahepatic portal hypertension. Two group of patients were divided as follows: 45 children in the first group had H-bypass operation with the use of right internal jugular vein. In 23 children of the second group bypass operations without dissection of internal jugular vein were performed. The age of children was between 1, 5 and 14 years. Various methods have been used to estimate the impact of one jugular vein ligation on CNS and cerebral blood supply: electroencephalogram, echoencephalography, rheoencephalography. The tests have been done prior the operation, 1-3 weeks after the operation and a year after it. All children had Doppler test before the operation to make sure that both jugular veins are permeable. 80% of patients had different kind of functional cerebral changes. In 90% of cases intracranial pressure and tone of microvascular bed were increased. One-sided ligation of the internal jugular vein in children does not cause cerebral hemodynamic and liquor-dynamic disorders and does not influence functional status of brain in the short-term and long-term postoperative period.
