[A differential approach to the surgical treatment of liver hemangiomas].

Treatment results and indications for surgery were analysed in 50 cases of hepatic hemangioma versus pattern of hemangiomatosis and size, site and extent of tumor. Surgery was performed in 41 (82%) patients. Radical surgery was possible and justified in as few as one-third of them. Palliative treatment including ligation and roentgen-endovascular occlusion of the hepatic artery and its branches, local ferromagnetic embolization of tumor and suturing and sclerotherapy of hemangioma were performed in 28 cases. End results were analysed in 33 cases followed up to as long as 8 years posttreatment. The extent and type of surgery for hepatic hemangioma should be different for each of the four patterns of the disease identified.

[Blood group assignment--a genetic marker of hepatic hemangiomatosis].

There is no single point of view on pathogenesis of hemangiomas. The authors investigated the ABO blood types in 52 patients with hepatic hemangiomas (Group 1) and 1000 control patients (Group 2). The study demonstrated 61.5% of the A blood type among the patients of Group 1. This was significantly higher than in the Group 2 and representative groups from literature (P less than 0.001). Taking into account that the cells of both blood and blood vessels are formed in embryos through the mesenchyma and the heritability of blood group antigens, it is supposed that the results obtained support the genetic determination theory of pathogenesis of hepatic hemangiomas.

[Embolization of the hepatic artery in the treatment of malignant tumors of the liver].

The results of therapeutic hepatic artery embolization (HAE) in 25 patients with malignant unresectable tumors of the liver are discussed. The proximal segments of the hepatic artery were occluded by metal spirals. Thrombosis of the portal vein was accepted as an absolute contraindication for HAE, and a tumor involving more than 50% of the volume of the liver and chronic hepatic insufficiency were considered relative contraindications. After the intervention signs of subjective improvement were noted in 73.9% and signs of objective improvement in 65.2% of cases. The mortality after HAE was 4.2%. The obtained results are evidence of the efficacy of proximal HAE as a method for the treatment of inoperable malignant tumors of the liver.

[Potentialities of angiography in the diagnosis and treatment of angiosarcoma of the liver].

Clinicoroentgenological evidence is described for 3 patients with nonresectable hepatic angiosarcoma. Two of these underwent therapeutic embolization of hepatic artery. Differential diagnosis between angiosarcoma and other hepatic malignancies by angiographic images seems impossible. Hepatic artery embolization can be employed as palliative treatment of advanced angiosarcomas.

[Clinical aspects of diagnosis and treatment of aneurysms of the splenic artery].

Literature data and original clinical evidence are reviewed concerning diagnostic and treatment aspects of splenic artery aneurysms (SAA). Five cases of aneurysms of the splenic artery trunk in 4 females and 1 male aged 23-54 are described. There was a case of a false SAA due to previous abdominal trauma and consequent pancreatitis. In another case SAA combined with cavernous hepatic hemangioma. Portal hypertension resultant from hepatic cirrhosis was seen in 3 out of 5 SAA cases. Two patients underwent embolization of the artery trunk proximally from SAA, three patients--ligation of the splenic artery with removal of the SAA and the spleen. Current methods of investigation are believed capable of SAA diagnosis before fatal complications, with differential approach to SAA evaluation warranting definition of surgical treatment scope.

[Embolization of the hepatic artery in hemangiomas of the liver].

Embolization of the proximal part of the hepatic artery was carried out in three patients with hemangioma of the liver who did not meet the criteria for radical surgery. Metal spirals were used for this purpose. Response was observed in all the cases. Patients were followed for 9-36 months. The data obtained suggest that embolization of the hepatic artery is effective and may be used for the treatment of inoperable vascular tumors of the liver.

Transcatheter treatment of splenic artery aneurysms (SAA). Report of two cases.

Splenic artery embolization with steel coils was performed in two patients who both had large splenic artery aneurysms and hepatic cirrhosis complicated by hypersplenism. A good clinical effect was noticed after the procedure. It was concluded that this treatment is safe and effective and decreases the risk of splenic artery rupture. It also corrects hypersplenism. Transcatheter embolization appears to be a preferable alternative to surgery in such cases.
