[The diagnosis of venous malformation of the orbits (author's transl)]

The authors describe the frequency, clinical features and methods of diagnosis of venous malformations of the orbits based on their own experience and on the relevant literature. Special attention is paid to plain film diagnosis and angiographic methods of investigation. Orbital phlebography is the most suitable method for demonstrating cavernous haemangiomas and orbital varices and for demonstrating the anatomy of the supplying vessels. For this, special apparatus and skills are necessary in order to obtain adequate, or optimal, phlebograms. The radiological features of venous malformation are described and a selection of typical phlebographic findings are illustrated. An attempt is made to evaluate other forms of examination. Possible aetiological factors in the development of venous malformation in the head and neck region are discussed.
