[Selective arteriography of the supra-aortic trunks by right humeral approach with a 4F catheter].

Three hundred and sixty seven patients were studied for cerebrovascular disease with intra-arterial digital subtraction. Examination were performed using a right transbrachial approach with a 4F catheter. Selective catheterization of the carotid arteries was possible in 98% for the left and 99% for the right. Image quality was consistently good or excellent. There was 2 neurologic complications and 1 local complication (hematoma) requiring surgery few weeks later. Selective carotid and vertebral catheterizations by the brachial route is safe, simple, accurate and rapid (15 mn) and can be employed in outpatients.

[Intra-arterial fibrinolysis of superior mesenteric artery embolism].

Intra arterial fibrinolysis for acute mesenteric embolism. Acute mesenteric ischemia has a poor prognosis because the diagnosis is often too late (greater than 12 h), leading to a difficult surgery in old patients. The lesions of the bowel don't always allow a single operative embolectomy but often need a resection when there is a long time interval between onset of symptoms and therapy. We report a case of acute embolism in the superior mesenteric artery with the clot located in its terminal part. A rapid diagnosis was made by arteriography and intra-arterial fibrinolysis was attempted with success permitting the complete cure of the affection, without sequellae. This treatment is only likely to be successful if it is carried out within 10-12 hours of the onset of clinical signs and symptoms.

[Pseudolinitis plastica of breast origin].

The most common type of gastric metastases secondary to carcinoma of the breast is the one showing a linitis plastica appearance. The roentgenologic aspect when performing an upper gastrointestinal examination with barium contrast is typical and allows the differential diagnosis with the primitive linitis. The linitis plastica type of metastatic breast carcinoma results from transmural infiltration of the stomach wall with initial deposit of tumor cells in the submucosal or subserosal regions. CT provide valuable information concerning the metastatic spread.

CT findings of laryngeal involvement in von Recklinghausen disease.

In two patients with laryngeal von Recklinghausen disease, CT demonstrated hypodense, well-defined, septated masses sparing the epiglottis, and with little enhancement after contrast medium injection. Additional cervical lesions, benign or occasionally malignant, may also be seen.

Alveolar echinococcosis of the liver: MR findings.

Nineteen cases of proven hepatic alveolar echinococcosis were examined by magnetic resonance (MR) and the results were compared with CT. Fibrous and parasitic tissue showed low signal both on T1- and, generally, on T2-weighted images. In a few cases a high signal on T2-weighted images may be observed, due either to central necrotic zones or to small peripheral cysts. Central necrosis was more easily identified by MR than by CT. However, MR seemed to be less effective than CT in allowing us to reach a positive diagnosis, due to its inability to show microcalcifications. In addition, MR may not reveal small lesions. In most cases T1-weighted images revealed more clearly than CT did the margins of the lesions and the hepatic extension, especially to hepatic veins, vena cava, and perihepatic spaces.
