Abstract EN

Background and Objective: This study was performed to assess the clinical outcome of surgically treated patients with posterior fossa tumors with signs and symptoms of hydrocephalus without pre-operative ventriculo-peritoneal shunt .

Methods and Material: we study 32 patients who underwent operations for posterior fossa tumors in the department of neurosurgery in Damascus University in the duration between 2012 and 2014.

The patients were divided into two groups, control group (A) underwent Ventriculo -peritoneal shunt prior to surgery for the tumor , and experimental group(B) were not treated with shunt prior to surgery for the tumor.

We follow the pateints for one month after tumor resection and then compare between two groups using the following parameters: Duration of hospital stay, postoperative complications including (cerebrospinal fluid leakage, pseudomeningocele ,meningitis, seizere and shunt complications), and final outcome at 1 month using modified Kranofsky performance scale .

Results: The mean duration of hospital stay in control group (A) was 95.1± 12.6 days with range between 70 and 120 days, and in experimental group(B) was 71± 12.6 days with range from 36 to 88 days .

the majority of patients had no complications in both groups[12pateints(70.6%) in group A and 9(60%) in group B].Final outcome after 1 month according to Kranofsky scale was similar in both groups.

Conclusion: This study showed that none of both methods( with or without pre- operative shunt ) had particular benefit over the other ,though, it is important to do ventriculo-peritoneal shunt befor surgery for relieving symptoms of raised intracranial pressure ,but also several post operative complications were related to shunt itself.
