Radioactive Coil Embolisation of Intracranial Aneurysms

Coil embolisation of intracranial aneurysms can improve the outcome of patients treated after subarachnoid haemorrage as compared to surgical clipping 1. Unfortunately, angiographic recurrences are not infrequent and although their clinical significance remains to be determined, they may be responsible for future ruptures2. In situ beta radiation, using coils ion-implanted with 32P, may prevent recanalization and thus improve long-term results of endovascular treatment. The present article will review the experimental data as well as present the clinical feasibility of radioactive coil embolisation of intracranial aneurysms.
