[Lumbar phlebography: anatomy and technique (author's transl)].

This article describes the normal radiological anatomy of the epidural veins whose understanding is necessary for the correct interpretation of venographic studies. Three ways of achieving adequate visualization of the epidural venous plexus are described. Experience with 80 cases is reported; a comparison has been made among the degree of visualization of the epidural venous plexus, the length of time, the cost and the amount of radiation received by the operator and patients during the performance of each technique. Preference is expressed for simultaneous injection of contrast media via two needles introduced into right and left femoral veins.

[Cholangiocarcinoma in a patient with hepatosplenic atrophy subsequent to thorotrast administration (author's transl)].

A case of cholangiocarcinoma observed in a woman of 38 following carotidographic examination with Thorotrast is described: the presence of radioactivity was also demonstrated by gamma spectrometry. The high mean dose absorbed by the liver (estimated at about 3,000 rad) together with the high relative biological effectiveness of the alpha contribution and the time lapse justify the hypothesis that the neoplasia was caused by irradiation.

Selective arterial embolization in renal tumors.

Selective arterial embolization with Gelfoam was performed in 45 cases of hypernephroma. In 33 cases this technique has been utilized as preoperative procedure and almost always (97%) nephrectomy was facilitated: 97% of the cases had slight or moderate operative bleeding; in 82% of the cases separation of the tumor-containing kidney from adjacent tissues was easy. Embolization has been employed in 12 inoperable patients and was effective mainly in management of bleeding. Angiographic controls after embolization (from 13 to 162 days) were performed 8 times and it was assessed that the efficacy of the procedure on primary tumor growth is limited in time by renal artery revascularization. The embolized patients never presented severe complications, except several episodes of transitory renal failure.

[Angiographic signs of the small intestine (two cases) (author's transl)].

The authors describe 2 cases of ileal carcinoid. They evaluate the advantages of selective angiography over the traditional radiologic methods, considering their cases and the 39 found in the literature. The angiographic signs of the lesions localized to the bowel wall are rather scarse and non-specific. The signs of mesenteric infiltration, which is precocious and conspicuous in this type of tumour, are more significant. Liver metastases, which are very frequent, are hypervascularized. The angiographic pattern may be similar to that found in some inflammatory diseases, but can be differentiated from that of other neoplasms of the small intestine.

[Radiological study of the neoplastic bladder].

Radiological methods useful in the examination of bladder tumours are reviewed, with particular reference to preoperative evaluation in accordance with the system. Examples are drawn from a personal series.
