Objectives: To find out the results of microsurgical excision of cerebral Arteriovenous Malformations.
Materials and Methods: This study was conducted from January 2005 to December 2007 at the department of Neurosurgery, PGMI Lady Reading Hospital Peshawar. A total of 12 patients of cerebral AVMs were included in this study. All the patients, who undergone surgery for cerebral AVMs, irrespective of their age and gender, were included in the study. Their clinical features, radiological reports, peroperative findings and surgical outcome were analyzed in different aspects.
Results: Of the total 12 patients, there were 8 males and 4 female patients. Their age ranged from 14 years to 36 years with the mean age of 23.4 years. Six patients presented with primary intracerebral hemorrhage, five cases with seizures and one patient was diagnosed incidentally after a minor head trauma. There were four patients with AVMs on left parietal region, one at right occipital, two at left occipital, two at frontal, one at right parieto occipital, one at left fronto parietal and one at right parietal region of the brain. In our study the out come of excision of AVMs at the eloquent areas of the brain was good in young patients as compared to the old patients. There was single mortality in our study.
Conclusion: Microsurgical techniques and appropriate radiological investigation is the basis for good surgical outcome.
