RESUMEN
A rarely observed digestive tract disorder, an intraluminal duodenal diverticulum is usually discovered during the course of a barium gastroduodenal follow-through examination. Radiological appearances are characteristic: intraluminal globular opaque image surrounded by a clear border. Clinical signs are absent or non-specific, and surgery is rarely indicated, except when the lesions are poorly tolerated or complications develop.

Results of vascular radiology and isotope examinations were compared in 48 patients with suspected ileocaval lesions (37 cases) or affections of the veins of the upper limb or superior vena cava (11 cases). Isotopic examination, which can be performed in ambulatory patients, respects normal hemodynamic conditions, is painless, and can be repeated, was found to give valid results, positive correlations with radiological investigation findings being present in 43 cases. Lack of correlation in the remaining 5 patients could have resulted from the period of time elapsed between the two examinations or the techniques employed during each investigation.

Two cases of tuberculosis of the oesophagus serve as an opportunity to review the clinical and radiological features of this rare condition. Generally situated at the junction of the upper and middle third of the oesophagus, the lesion is found opposite the invaded inter-tracheobronchial mediastinal nodes which may give rise to a fistula. Confirmed by oesophagoscopy, direct bacteriological examination, oesophageal tuberculosis is usually cured without sequelae by antituberculous therapy.

The administration of a vasodilator substance is followed by the development of a higher contrast gradient in a given film in comparison with a reference X-ray carried out in the same subject under comparable technical conditions. Comparative densitometric measurement of the contrast gradient in the two successive arteriographic series, one with and one without the injection, arterial or venous, of a vasodilator substance (Couramine-Rutine) represents a valuable method for the study in man of the action of the substance in a visceral territory. The present study was limited to the kedney (79 cases), ans the territory of the superior mesenteric (46 cases). The absence of any densitometric difference between the two renal series at too low doses of vasodilator substance leads to the supposition of the possibility of a threshold dose of pharmacological activity.

The authors report the case of acute dissection of the aorta (type I) with sudden aortic incompetence occurring in a young lady of 25 years of age with Marfan's syndrome. An urgent operation had a successful outcome; the ascending aorta was resected in toto, and replaced with a prosthesis, the coronary arteries being reimplanted.

Despite its imperfections, arteriography, when it demonstrates aneurysms, is an important element in diagnosis in all those cases in which histological findings are not definitive. It should be carried out before renal biopsy, given the risk of traumatic rupture of a possible aneurysm. The discovery of isolated distal arterial stenoses is not characteristic, though in the presence of a suggestive clinical picture, amy be considered as an argument in favour of the diagnosis. They occur frequently in the arteries of the digestive tract even in the absence of any abdominal symptoms or signs. Arteriography also has a prognostic value in establishing the extent of arterial lesions and, finally, is useful in the diagnosis of certain complications such as visceral haematomas and digestive haemorrhages. We thus feel that polyarteritis nodosa should be the object of a complete vascular exploration, including aortography with selective renal studies but also coelio-mesenteric opacification. In the light of the clinical context, the distal limb arteries may also be explored. Thus the diagnosis of polyarteritis nodosa is not purely histological but also arteriographic.
