Bifrontal Biparietal Cruciate Decompressive Craniectomy in Pediatric Traumatic Brain Injury.
BACKGROUND: We investigated a novel surgical approach to decompressive craniectomy (DC), the bifrontal biparietal, or "cruciate," craniectomy, in severe pediatric traumatic brain injury (TBI). Cruciate DC was designed with a fundamentally different approach to intracranial pressure (ICP) control compared to traditional DC. Cruciate DC involves craniectomies in all 4 skull quadrants. The sagittal and coronal bone struts are disarticulated at the skull to allow the decompression of the sagittal sinus and bridging veins in addition to permitting cerebral expansion, thereby maintaining cranial compliance.
OBJECTIVE: To characterize ICP control with cruciate DC in pediatric TBI.
METHODS: We performed a retrospective review of TBI patients who underwent cruciate DC. We investigated mortality and preoperative and postoperative ICP. Group 1 underwent medical therapy prior to DC and Group 2 required immediate DC.
RESULTS: Fifteen of 18 patients survived. In Group 1, mean preoperative ICP was 18.5 mm Hg and mean postoperative ICP was 11.5 mm Hg. In Group 2, mean preoperative ICP was 27.3 mm Hg and mean postoperative ICP was 15.0 mm Hg.
CONCLUSION: Cruciate DC was associated with lowering ICP. We observed acute drops in ICP and long-term ICP control. The floating bone struts of the cruciate DC permits the decompression of the sagittal sinus and bridging veins, with maximal relief of cerebral edema.
