Abstract Background: Unpredic table critical bleeding may occur from routine method of division and coagulation of the occipital sinus in pediatric posterior fossa surgery when it represents the main venous drainage. We describe safe technique with curved hemostat clamps to minimize or even prevent bleeding from this site especially in pediatric patients. Aim of Study: This study compared between two groups; a group where we open the dura with clamps and the other group where the dura is opened with routine division of the occipital sinus. Patients and Methods: This study divided the patients into two group: Group A: 20 patients where the dura opened with hemostat clamps (Hemostat clamp technique) as described in detail below. Results: The mean age in our study was 15.95±13 months, the mean blood loss was greater in (B) group than it was in (A) group. In (A) group: Mean blood loss was 35.2±16.4 in comparison to 159.25±99.8 in (B) group. Conclusion: This study applied this safe technique and compared it with the routine coagulation and division of the occipital sinus that carries a major risk of bleeding and swelling by comparison between two groups.
