[A case of surgical correction of the inferior vena cava obstruction with Budd-Chiari syndrome].

A 37-year-old man is presented with Budd-Chiari syndrome associated with a membranous obstruction of the inferior vena cava. Clinical symptoms were ascites, leg edema and dilatation of the superficial abdominal veins. Aggressive surgery was carried out for this case. Midsternal incision and right subcostal oblique incision were made, and hepatic segment of the inferior vena cava was reconstructed using pericardial patch after endovenectomy and partial cardiopulmonary bypass was used without temporary interruption of liver circulation. Blood flow from the right hepatic vein was restored. Postoperative course was not eventful and this patient remains free of any evidence of ascites and liver dysfunction after operation. This procedure may be useful particularly for protecting the liver function which is damaged by hemostasis.

Creutzfeldt-Jakob disease with demonstration of virus-like particles.

Two kinds of virus-like particles, doughnut-shaped particles and particles with dense core, were discovered in a brain tissue from a patient with Creutzfeldt-Jakob disease. The two types of virus-like particles are similar to immature type C and type C particles. although no direct relationship between Creutzfeldt-Jakob disease and these virus-like particles can be established, these facts may suggest that viruses play some role in the pathogenesis of Creutzfeldt-Jakob disease.

[Cerebro-vascular accident during pregnancy (author's transl)].

Cerebro-vascular accident is an uncommon but formidable complication of pregnancy. Faced with these cases, the neurosurgeon and obstetrician might differ in the planning of the treatment, when the interests of mother and child appear to conflict between them. From our clinical data of 5 cases and review of the literatures, the following points should be considered for the management of a cerebro-vascular accident during pregnancy. (1) The possibility of cerebro-vascular accident should be considered in any pregnant patients with neurological symptoms, and full investigation should be done if clini-indicated. (2) Aneurysm and angioma are most often encountered in pregnant patients with a cerebro-vascular accident. (3) Unless labour begins during investigation, a cerebral lesion should be treated before delivery, irrespective of the stage of pregnancy and the method of treatment should be decided primarily on neurosurgical grounds. (4) The time of onset of cerebro-vascular accident may be related to the hemodynamic and hormonal change. It occurs more frequently after the second trimester, when the blood volume and cardiac output reach their peak. (5) Pregnancy per se does not influence the mortality from a cerebro-vascular accident in pregnant patients.
