In 59 patients having non-operable malignant renal tumours, palliative trans-catheter embolization was performed. In 42 of them follow-up observations were realized over 18 months. The average survival rate was then 43% of cases. Local tumour growth was documented in 9 patients (23%) due to recanalization of the embolized arteries (13%) and to non-occluded collateral vessels (10%). The choice of suitable embolizing materials mainly influences the therapeutic result: Oily contrast labeled amino-acid Ethibloc is considered to be the material of choice for safe application and reliable vascular distribution causing persisting occlusion of the renal arteries.
In a retrospective study of 47 cases of chondromalacia proved by operation, a correct diagnosis had been made by arthrography in three cases. In 44 patients a false negative finding had been obtained. A prospective study was carried out comparing single and double contrast arthrography as well as double contrast arthrotomography and scintigraphy in ten patients with typical chondropathia. It was confirmed by arthroscopy in nine cases. Only two patients with severe chondromalacia showed abnormal findings by arthrography or scintigraphy. Our investigation has led to the conclusion that arthrography is not a suitable method for demonstrating idiopathic chondropathia of the patella.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
