In 50 patients subjected to aorto-femoral arteriography, the examination was carried out with and without the addition of 1 cm3 of 2% lidocaine per 10 cm3 of contrast medium; in 43/50 lidocaine led to a more or less notable reduction in pain without side-effects.
The angiographic findings in 18 patients with endocrine tumors of the pancreas are analyzed. A literature review (262 cases) is performed in order to assess the accuracy of angiography in diagnosing islet cell tumors, in particular multiple and small (less than 1 cm) lesions. Problems of differential diagnosis of pancreatic and extrapancreatic structures and lesions are discussed.
Selective arteriography of the carotid and vertebral arteries by the femoral route was carried out in 225 cases. The technique, results, indications and contraindications are reported and discussed together with complications.
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 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.
