[Embolization with gelatin-impregnated microspheres].
OBJECTIVE
This paper presents a new, easy to handle material for embolisation which comes up with sharply defined particle size and spherical shape, very suitable for peripheral embolisation in the small end arteries.


METHODS
In 13 superselective embolisations with coaxial catheters the gelatine coated microspheres-sized 300-500, 500-700, 700-900 microns--were injected in the region of bronchial arteries (n = 7), vertebral bodies (n = 4) and pudendal arteries (n = 2).


RESULTS
In all cases complete occlusion of the desired vessels was achieved. With the exception of one transient dysesthesia in the relevant dermatome during embolisation of the third lumbal vertebra, no adverse effects were noted. The microspheres were suspended in contrast medium and could be easily located by indirect methods, and hence the embolisation procedure was well controlled.


CONCLUSIONS
Compared with other embolisation materials the ready-for-use gelatine coated microspheres due to their physical properties are an excellent alternative to superselective embolisation materials of end arteries.
