Endovascular Treatment for Ruptured Cerebral Aneurysms in Acute Stage
Since the introduction of endovascular embolization with Guglielmi Detachable Coils (GDC)1–3in April 1997, we have performed 56 endovascular treatments for ruptured cerebral aneurysms in the acute stage based on our definition of candidates for this modality. Overall outcomes are as follows. 1) Rebleeding within one year was limited to one case (2.5%). 2) Vasospasm occurrences: four cases (7.1%) infarction and three cases (5.4%) as transient ischemia. 3) H&K Grade IV; 60% of cases resulted in improved outcomes. 4) H&K Grade II: One case of rupture during an operation. 5) Three out of five older subjects (over 80 years old) resulted in GR or MD. In this study, we reviewed endovascular embolization in acute stage in terms of candidates and technical problems.
