[Diagnostic position of cavography (author's transl)].

Since computerised tomography and sonography are both capable of direct identification of retroperitoneal structures even if their vascularisation is poor, indication for cavography has been reduced. The majority of cavographies performed during the past three years were executed for the purpose of optimal preparation of surgery of a tumour identified via computerised tomography, sonography or arteriography. In a few cases only was the indication for cavography necessary on account of thrombosis or in order to clarify pre-operatively any anomalous structures. Due to the rapid development of the non-invasive techniques it is expected that indication for cavography will be reduced even further in future.
