[Value of lower limb arteriography in iatrogenic ergotism. A report on a case (author's transl)].

The authors report a further case of ergotamine poisoning with acute ischemia of the four limbs. Arteriography was carried out during the course of the vascular accident and at a later period when clinical signs had disappeared. Arteriography confirmed the presence of diffuse vascular spasm appearing as thin filiform arteries without any signs of a collateral circulation. Normal conditions were restored in the iliac, femoral, and leg arteries after stopping ergotamine administration. Arteriography appears to be of great value when there is any doubt during the acute clinical stage, in order to assist diagnosis and to confirm and verify the integrity of the vascular network at a later stage.

[Pericardial effusions (85 cases): radiological aspects (author's transl)].

A radiological study of 85 patients with acute pericarditis and effusion included a group of 35 cases observed before the introduction of ultrasonography and a second group of 50 patients in whom the presence of pericarditis had been confirmed by this investigation. The most important conclusions established were the following: --Absence of radiological signs in 55% of cases (group 1 : 46%, group 2 : 60%); normal heart size in 54% (group 1) and 78% (group 2), and increased size in 34% (group 1) and 20% (group 2). --Hilar manifestations (overlapping and obscuring of the left hilar region) in 26% of cases with a clear predominence of the left forms (14 out of 22). The cardiomegaly was not significant in 28% (group 1) and 14% (group 2). --The high frequency of pericarditis with a normal heart size has to be emphasized. The diagnostic value of hilar manifestations is also mentioned; the sign of left hilar overlapping is described in greater detail. --An overall comparison between the two groups shows, more particularly, the equal importance of left hilar manifestations for the radiological diagnosis of pericarditis. In a general way, it would appear that these hilar signs are the only elements which enable objective diagnosis of pericardial effusions on standard films.

[Radiological signs of primary sarcoma of the kidney in adults : a report on 5 cases (author's transl)].

Primary sarcomas of the kidney are extremely uncommon and the results of their angiographic study are rarely reported. A study of five cases that were confirmed histologically demonstrates the absence of specific clinical and urographic findings. Arteriographic appearances are variable and not related to the histological type. The poorly vascularized forms are traditionally the most frequent (2 out of 5 cases) but are not fundamentally different from adenocarcinomas. The diagnosis can be suspected, however, when there is an infiltrating peripheral tumor extending well beyond the capsule. The hypovascularized pseudocystic forms raise the same arteriographic problems as the adenocarcinomas. Arteriography can diagnose malignancy, but the diagnosis of sarcoma is usually impossible before operation.

[Arteriography in a case of single coronary artery with myocardial ischaemia (author's transl)].

Coronary arteriography is the only examination by which the diagnosis of single coronary artery may be made in vivo by demonstrating the presence of an entire coronary system arising from a common trunk. The discovery may be made under two distinct sets of circumstances: 1 degree Coronary ischaemia in a young subject. Arteriography confirms the diagnosis and the customary 2 degrees Coronary ischaemia in an older individual. Arteriography shows atherosclerotic lesions in a single coronary artery. The severity of the condition is related to the proximal character of the stenoses. The most logical therapeutic approach is aorto-coronary bypass if the quality of the distal network as seen at arteriography makes it possible.

[Multisite cervico-mediastinal venous samples for radioimmunologic determination of parathormone in primary hyperparathyroidism. Results in 24 surgically confirmed cases].

Multisite cervico-mediastinal venous blood samples were collected fort the estimation of parathormone before operation in twenty four patients subsequently confirmed at surgery to have primary hyperparathyroidism. The examination made it possible to lateralise a single (single adenoma: 18 cases) or predominant lesion (multiple adenomas or hyperplasia: 6 cases), in 15 of them (62%). In patients with a single adenoma, exact lateralisation was obtained in 12 out of 18 cases (9 had selective samples with 7 accurate lateralisations). This lengthy and costly examination is essentially of value in localisation and should be used essentially in patients with virtually definite primary hyperparathyroidism and in whom the responsible lesion has not been discovered at exploratory operation.

[Indications for arteriography and determination of parathyroid hormone in staged venous samplings in primary hyperparathyroidism].

The information provided by parathyroid arterigraphy and staged venous sampling with parathormone estimation is essentially related to localisation and is of little diagnostic value. It is not justifiable on a routine basis before all operations. These techniques are particularly useful in patients with practically definite hyperparathyroidism and who have already undergone a negative exploratory operation or surgery with insufficient excision.

[Diagnosis at arteriography of parathyroid adenomas. 45 cases (author's transl)].

The authors report the results of parathyroid arteriography in 45 patients in whom diagnosis was certain, with surgical confirmation of the radiological findings in 44. In this group arteriography led to the exact localisation of the parathyroid adenoma in 21 out of 34 cases. The angiographic signs of parathyroid adenomas are not constant and a negative arteriogram under no circumstances eliminates the possibility of an adenoma being present. In addition, the angiographic signs do not all possess the same significance, some being merely suggestive without definitely indicating the presence of an adenoma. By contrast, when there were highly suggestive or definite signs at arteriography, an adenoma was found surgically at the expected site in 21 of 22 cases. Finally, the authors stress the importance of comparison of the results of arteriography and thyroid scan in order to eliminate thyroid adenomas, as well as the necessity of a photographic substraction involving the different phases of the arteriogram, since this may reveal adenomas invisible on standard arteriography films.

[Angiographic study of coronary artery disease patients receiving circulatory assistance by intra-aortic diastolic counter-pulsion (author's transl)].

In patients receiving circulatory assistance by intra-aortic counter-pulsion for myocardial infarction, angiography may be carried out by the retrograde femoral route. It should include left ventriculography makes it possible to assess the number of segments which contract and to draw a correlation between the kinetics of a segment and its vascularisation. Vascular studies should be carried out at the time of maximum effect of the pump, i.e. from the 18th hour onwards. Indications for angiography are as follows: isolated or mechanical cardiogenic shock, early recurrence of infarction, refractory left ventricular failure and persistent arrhythmias. In cardiogenic shock and refractory left ventricular failure, the coronary lesions are diffuse. All our patients died. By contrast, in the group with early recurrence of infarction or persistent arrhythmias surgical treatment is often possible.

[Radiological diagnosis of acute kidney abscess in adults. Early diagnosis apropos of 7 cases].

The authors report, in 7 cases, their experience of the early diagnosis of renal abscess. They emphasize the importance of recognising this disease by comparison of the findings of intra-venous urography and the clinical signs. They were thus able to avoid arteriography and surgical operation in 6 cases. The diagnosis depends on the finding of a mass in the right kidney (5 cases out of 7) on intravenous urography, usually in the upper pole (4 cases out of 7). This space-occupying lesion may be accompanied by a certain number of signs which are inconstant and not specific, e.g. disappearance of the normal calyx pattern which disappears under compression and is probably related to inflammation. In fact, this association of a tumour and fever, due to deep pus formation and urinary infection, suggests the diagnosis and leads to the prescription of antibiotics. The disapperance of the clinical and radiological négative signs within 10 days confirms the diagnosis. The persistence of the space-occupying lesion requires arteriography which will make the difference between chronic abscess and carcinoma.
