Comparative Study of Treatment Results between Surgical Neck Clipping and Endovascular Coiling on the Ruptured Middle Cerebral Artery Aneurysms

ABSTRACT

OBJECTIVE: The treatment modalities of cerebral aneurysms mainly consist of surgical neck clipping of aneurysms and endovascular embolization. Through comparing of the treatment results between two methods especially focused on their complicatons, the authors present the efficacy of the treatment modality in ruptured middle cerebral artery aneurysms. METHODS: Patients who admitted due to ruptured middle cerebral artery aneurysm between January 1998 and December 2002 were selected. They have done surgical neck clipping or endovascular embolization which employed platinum coil. Treatment methods were chosen in random fashion. The patient's clinical state were determined before, during, and after the treatment by using Hunt and Hess grade and Glasgow outcome scale(GOS). According to Fisher grade was classified based on the amount of hemorrhage. Statistical analyses were done with Student t-test, Pearson's correlation coefficient, and Mann-Whitney U test. RESULTS: Average follow-up period was 24 months(5 days-36 months) in surgery group and 26 months(8 days-36 months) in endovascular embolization group. There was no statistical significance regard to sex, age, patient's Hunt and Hess grade on admission, the Fisher grade, and aneurysmal size. There was no significant difference between GOS of two groups in statistically(p>0.05). CONCLUSION: This comparative study of reveals no significant difference in neurologic outcomes between two treatment modalities.
