Transcatheter therapy in angiography: indications, techniques, and illustrations.

This paper reports the history, methods,and indications currently accepted for transcatheter management of two distinct pathologic states. Reported are numerous cases from available literature and five cases from our own experience, supported by illustrations from angiography performed in this institution. It is hoped that the technologist has gained an understanding of the indications and methods for performing transcatheter therapies and that the growing interest in this adaptation of radiologic capabilities will serve to enhance the technologist's scope of operation as a member of the health-care team. The future of diagnostic angiography cannot be predicted, pending full evaluation and implementation of the rapid advances in other diagnostic modalities. The future of transcatheter therapeutic measures, however, appears worthy of continued vigorous investigation.
