[Superselective interventional angiography].
The authors report on the clinical application of superselective interventional angiography within the framework of revascularisation and occlusion. A coaxial catheter system is used for probing, consisting of an F 5 angiography catheter as guiding catheter and an F 3 catheter as internal catheter. The internal catheter is equipped with a shaft with segments of different flexibility and can take up a guide wire of 0.018" that is sufficiently stable to be rotated and guided. The interplay between the guide wire, which can be manipulated, and the flexible internal catheter enables superselective probing even of peripheral vascular areas. As may be required by the basic disease, the necessary interventional measures can be taken via the superselectively placed microcatheter. Superselective interventional angiography is indicated as an occlusive measure in preoperative vascular occlusion followed by palliative tumour resection, embolisation in haemangioma, chemoembolization in tumours of the liver. Superselective angiography is used for revascularisation in the local lysis of peripheral vessels. Due to the on-target superselective approach, side effects are markedly less than those observed with the interventions performed to date.
