The results of angiographic studies of abdominal masses.

This study reveals the continuing great viability of angiography in the investigation of abdominal masses. It is a fundamentally important procedure within the context of presurgical evaluation. Certain points should be underlined. - The radiological definition of the histological nature of an abdominal mass during angiography remains difficult, practically impossible in certain regions. - Borrowed vascularizations still pose complex diagnostic problems at different levels. - The benefit of angiography should be compared with other modern radiodiagnostic methods, especially the less aggressive ones. - The importance of each of these points has led us to develop them separately: - The diagnostic reliability of angiography in abdominal masses (from anatomico-radiological correlations). To be published - The borrowed vascularisation of abdominal masses. To be published - The tomodensitometry of abdominal masses. To be published - Diagnostic strategy in case of an abdominal mass.

Abdominal Neoplasms

The parasitic blood supply of abdominal masses.

Many lesions, and particularly hyper-vascularized ones, acquire an aberrant blood supply. These parasitic vascular supplies are defined as tumour vascularizations derived from neighbouring organs or structures, and supplement the normal blood supply of the diseased organ. Their existence is essential for the angiography of abdominal masses. We selected 35 cases of abdominal masses with parasitic vascular networks. Twenty-four belonged to an initial review of 117 angiographic studies of abdominal masses. Eleven have been added in accordance with the theme of this work. Parasitic circulations should be taken into account because of their effects on the angiographic technique, their diagnostic possibilities and limitations, and their importance in the management of the patient.

Abdominal Neoplasms

[Topographic diagnosis of pheochromocytoma. Value of computerized axial tomography].

The localisation of a pheochromocytoma is difficult and sometimes hazardous. There are many radiological techniques of varying sensitivity and the risks of hypertensive crises or of cardiovascular collapse are not negligeable (especially during arteriography and venography). Abdominal computerised axial tomography (CAT) would appear to be of considerable value. It gives a very precise localisation without any risk. Three personal cases confirm this opinion. The first case was of a 38 year old man with an extra-adrenal pheochromocytoma localised in the pelvis of the left kidney by CAT (after negative intravenous urography); the second case was of a 54 year old man with a left adrenal pheochromocytoma confirmed on CAT (after 2 negative aortic arteriogrammes and adrenal venography); the third case was of a 39 year old woman with a para aortic pheochromocytoma, diagnosed on CAT (after negative intravenous urography). These three cases bring to 43 the total number of reports of pheochromocytoma localised by abdominal CAT. When this method is compared with intravenous urography and aortic arteriography, abdominal CAT is over three times more sensitive than intravenous urography (90% compared to 26%) and also more sensitive than arteriography (90% compared to 76%). The false negative results on CAT usually involve small tumours (diameter less than 30 mm). The new generation of CAT should reduce these errors. The great advantage of this investigation should change the order of the radiological examinations in the localisation of pheochromocytoma. It would seem logical to carry out an abdominal CAT as soon as biological confirmation of the hypersecretion of catecholamines had been obtained. The other radiological investigations (especially aortic arteriography) should be reserved for cases with negative abdominal CAT.
