[Radiologic diagnosis of abdominal aortic aneurysm. Value of abdominal radiography, ultrasonic tomography and abdominal aortography].

Radiological diagnosis of arteriosclerotic abdominal aortic aneurysm is discussed. This review is based on the evaluation of 70 abdominal plain films and 58 aortograms. In addition, 11 aneurysms have been examined by ultrasound tomography (grey-scale technique). In 15% of patients referred with suspicion of aneurysm, the diagnosis could not be confirmed radiologically or operatively. The diagnosis of abdominal aortic aneurysm can be established in 80% of patients on the basis of the abdominal plain films. Ultrasonography gives better results as a screening method, since it renders a definite diagnosis possible in about 98% of cases and unnecessary arteriography can thus be avoided. However, preoperative abdominal aortography remains indispensable for demonstration of the exact anatomic details and pathologic changes in the large abdominal and pelvic arteries. The risk involved in this examination are minimal. Suprarenal or combined supra- and infrarenal aneurysm were found in 9% (5 patients), and renal artery stenosis or obstruction in 12% (7 cases). Obstruction or stenosis of the celiac artery and the superior mesenteric artery were present in only 2 patients with suprarenal expansion of the aneurysm. The angiographic-anatomic correlation is excellent, and only very infrequently is it impossible to determine exactly the distal extent of the aneurysm (2 patients).

[Angiography in Crohn's regional enteritis. Its relation to conventional radiological, endoscopic and micro-angiographic findings].

There has been a definite increase in the incidence of Crohn's disease in recent years. A particular feature of this disease is the high incidence of recurrence after surgical removal of affected portions of the gut. This may be due to a resection carried out through a diseased segment and this stresses the importance of recognising early changes. This is not possible by conventional radiology (small bowel examination, barium enema) and is therefore an indication for pre-operative visceral angiography. The results obtained in ten patients, who subsequently came to surgery, were compared with the findings on conventional radiology and endoscopy. Angiography proved the best method for the early demonstration of inflammatory changes. This was confirmed by histological examination of the resected specimen.

Pelvimetry in breech and cephalic presentation.

Pelvic measurements in a group of 115 women delivering in breech presentation were compared with those in a group of 100 delivering in cephalic presentation. The average pelvic measurements were all a few mm larger in the breech cases and the average sum of the outlet diameters was significantly larger. Pelvic disproportion was not more common in breech presentation and no support was found for the theory that large pelvic measurements predispose to breech presentation. The small differences found are attributed to the moulding of the pelvis occurring during parturition.

[The angiographic findings in focal nodular hyperplasia of the liver(author's transl)].

Four cases of FNH are described; the angiographic appearances are detailed and problems in differential diagnosis are discussed. FNH presents as a hypervascular benign space-occupying process in the liver, with a typical vascular structure and intensive prolonged and sharply demarcated parenchymal staining. It can be distinguished from malignant lesions in the liver by the absence of tumour vessels, infiltration and occlusion of vessels.
