[Angina abdominalis: Clinical findings and therapy (author's transl)].

Angiographic and clinical findings of angina abdominalis are demonstrated by the clinical course of four patients. Two of them suffered from athero-sclerotic stenosis and the remaining two from compression of the coeliac trunc respectively the upper mesenteric artery by fibrotic strings. One patient was treated by an interposition of a saphenous vein graft another one by tissue decompression. Two patients were not operated upon, because one of them had sufficient collateral circulation on angiography, and the other denied an operation, he died one year after diagnosis because of an occlusion of the coeliac trunc and the upper mesenteric artery with following gangrene of the small and large intestine. Danger of complete intestinal necrosis following arterial vessel occlusion as well as reconstructive operative procedures on arterial occlusion should be considered.

[Catheter embolisation of a bleeding renal hamartoma, with a contribution to its angiographic diagnosis].

Hamartomas of the kidney, often associated with tuberous sclerosis, have a typical angiographic appearance. Despite the similarity of the angiographic signs with malignant renal tumours, it is possible to differentiate these, as was shown in two patients which we have documented. If there is massive bleeding, fibrin embolisation carried out at the end of a diagnostic angiogram may lead to occlusion of the vessels and stop the bleeding. This was demonstrated in one of our patients.

[Scintigraphic findings in splenic vein thrombosis].

After a brief review of the literature concerning scintigraphy of the spleen, its vascular system is described. The presence of numerous anastomoses makes it likely that occlusion of the splenic vein will usually not lead it any parenchymal damage. In five patients with angiographically confirmed spenic vein thrombosis it was shown that radio-colloid scans always demonstrate an enlarged spleen. Poor colloid uptake was thought to be due to a venous reflex mechanism leading to a reduction in the arterial blood supply. The statement found in the literature, that the spleen cannot be shown scintigraphically if the vein is thrombosed, has not been confirmed by us. We tend to the view that the apparent absence of a splenic scan was due to geometric causes.

[Catheter embolisation of the splenic artery as treatment for acute bleeding from varices (author's transl)].

Embolisation of the splenic artery with fibrin foam, in order to stop acute bleeding from varices, was carried out in two patients. This was performed immediately after diagnostic arterial indirect demonstration of the portal vein; by this method it is possible to achieve at least a temporary cessation of bleeding from oesophageal or gastric varices. The procedure is indicated in desparate situations, if intubation has been unsuccessful or has had to be discontinued, when endoscopic sclerosis is contra-indicated or when an emergency shunt cannot be carried out because of poor liver function or the general condition of the patient. Permanent results cannot be expected and recurrence of bleeding cannot be avoided. The use of splenic embolisation depends on stopping the acute bleeding in order to obtain an interval during which liver function can be improved so that a decompressing shunt operation becomes possible subsequently.

[The scope and limitations of cavography in tumour diagnosis (author's transl)].

Fourteen cavograms showing abnormal findings were selected from a total of 500 examinations; in these the diagnosis had been confirmed surgically, histologically, at autopsy or by the clinical course. The aim of selecting this material was to determine retrospectively the accuracy to cavography in localising retroperitoneal masses, to determine their extent, whether it is possible to diagnose the type of tumour and whether the presence of thrombi can be regarded as a sign of invasion of the cava by malignant tumour. The abnormal cavograms were evaluated with respect to certain radiological signs and the diagnostic value of individual signs was calculated statistically. It was found that the only fairly reliable sign of tumour thrombus consists of an ill-defined impression with breaks in the continuity of the vascular margin. All other radiological signs examined were found to be non-specific.

[The angiographic appearances of liver haemangiomas (author's transl)].

Thirteen cases of cavernous haemangiomas of the liver are described, and the clinical features, diagnosis and treatment are discussed. The purpose of this paper is to show the value of selective coeliac angiography in the differential diagnosis. The most important angiographic findings in cavernous haemangiomas of the liver are: supplying arteries of normal width, prolonged stasis of the contrast medium producing the appearance of spotty contrast depots, frequently, sharp delineation of the tumours; no A-V fistulae and no tumour vessels. Other hypervascular liver tumours must be distinguished from these, particularly hepatocellular carcinomas and sarcomas, as well as the rare haemangioendotheliomas.

[Splenic artery ligature and latero-lateral anastomosis in portal hypertension (author's transl)].

A new type of shunt for decompressing portal hypertension is described, consisting of ligation of the spleno-renal anastomosis. This reduces the pressure in the portal territory and in the dangerous gastric and oesophageal varices. In addition the procedure also abolishes the marrow inhibition due to splenic activity without removing the spleen and maintaining part of the portal circulation. The advantages and disadvantages of various decompression operations are discussed and compared with other methods in current use.

[Radiologic diagnosis of secondaries of tumors of the testicle (author's transl)].

For the radiologic diagnosis of secondaries of testicular tumors we use conventional plain films of chest and abdomen, IVP or infusion urography, tomography of the retroperitoneal space with or without contrast media and, according to the suspected site of metastases, further special radiologic techniques like lymphography, cavography, azygography, venography of the lumbar vein or, occasionally, aortography. The techniques are described, their value and limits discussed.

[Cancer arising on cirrhosis of regenerative node (author's transl)].

12 patients with cancer arising from a cirrhosis of the liver and 8 patients with regenerative nodes in a cirrhotic liver have been examined with scintigraphy, serial scintigraphy, angiography and biopsy. The results show that defects in the parenchyma of the liver can be shown with relative certainty using conventional scintigraphy with radiocolloids. But nothing can be said about their nature. Because of the simplicity of this technique and the minor claims on the patient scintigraphy should be the first diagnostic step. If angiography is contra-indicated serial scintigraphy may further elucidate the effects. When, however, angiography can be done, it will offer the best chance of differentiating between cancer and regenerative nodes on the basis of cirrhosis.
