Surgical treatment of Budd-Chiari syndrome caused by short segmental lesion of inferior vena cava and major hepatic veins / 中华普通外科杂志

Objective　To evaluate the results of radical resection for the treatment of Budd-Chiari syndrome (BCS) caused by short segmental lesions in inferior vena cava (IVC), and major hepatic veins (MHV).　Methods　In this series, resection of IVC occlusive segment and orthotopic artificial vascular graft transplantation were performed in 42 patients. Resection of major hepatic vein, hepatic venous plasty and orthotopic transplantation with artificial vascular graft were performed in 10 patients. Resection of major hepatic vein, anastomosis between hepatic vein and right artrium in 3 cases. Percutaneous transhepatic angioplasty in 10 cases.　Results　One patient died of complication. 58 cases were followed up for an average of 30 months. 3 cases in interventional group suffered recurrence and one in surgical group had recurrence.　Conclusions　The treatment of BCS by resecting inflicted segment of IVC or hepatic veins and orthotopic artificial vascular graft transplantation effect a radical cure in most cases.

The diagnosis and treatment of Budd-Chiari syndrome with inferior vena cava thrombosis / 中国普通外科杂志

Objectives To evaluate methods to diagnose Budd-Chiari syndrome with inferior vena cava (IVC) thrombosis.Methods 31 cases underwent phlebography, 28 cases received color Doppler sonography preoperatively. Radical thrombectomy was carried out in 28 cases. Results IVC thrombi was found by phlebography in 24 cases, and by color Doppler sonograhy in 25 cases. There was no intraoperative death, nor acute pulmonary embolism.All patients were discharged uneventfully. Follow-up of 6 to 80 months found recurrence in 3 cases.Conclusions Large or lateral thrombi can be easily diagnosed by phlebography. Fresh or floating thrombi often missed by phlebography could be rushed out by blood stream at the time IVC was incised.The thrombi adhered to the IVC wall could be taken out with large balloon catheter or manually.

THE OBSERVATION ON THE ULTRASTRUCTURE OF THE TEGUMENT OF ORIENTOBILHARZIA TURKESTANICA VAR. TUBERCULATA CERCARIAE / 中国血吸虫病防治杂志

Through transmission electron microscope,the ultrastructure of the tegument of Orien-tobilharzia turkestanica var. tuberculata cercariae was observed. From exterior to interior, the tegument can be divided into five parts,i. e. ,glycocalyx,external plasma membrane,ma-trix, basal plasma membrane and basement layer. The cell boundery is absent in the matrix, there is no subcellular structure but is filled with abundant dense particles. The thickness of this layer varies markedly so the surface of the cercarial body can be either convex or con-cave. There are two types of dense bodies (cercarial-type inclusion bodies) in this layer. Its formation,function and the relation with the glycocalyx are discussed.
