[Repair of the dura mater in children using xenogenic pericardium]
Insights
Xenogenic calf pericardium offers a successful alternative for dura mater reconstruction in pediatric neurosurgery. This biomaterial addresses shortages of traditional grafts and demonstrates durability for cranial and spinal procedures.
Area of Science:
- Neurosurgery
- Biomaterials Science
- Pediatric Surgery
Context:
- The use of autologous and allogenic tissues for dura mater reconstruction is limited by availability and donor site morbidity.
- Xenogenic materials present a viable alternative for addressing tissue shortages in reconstructive neurosurgery.
Purpose:
- To evaluate the five-year clinical experience with xenogenic calf pericardium for dural reconstruction in pediatric patients.
- To assess the efficacy and safety of xenogenic pericardium as a substitute for traditional dural grafts.
Summary:
- A retrospective analysis of 50 pediatric cases using xenogenic calf pericardium for dural plastic operations over five years.
- The biomaterial was successfully employed in reconstructions of the posterior cranial fossa, cerebral convexity, and skull base dura mater.
- Satisfactory incorporation was achieved by adhering to specific surgical techniques, including appropriate graft sizing, intradural placement, and meticulous suturing.
Impact:
- Xenogenic calf pericardium effectively addresses the scarcity of allogenic collagenous tissues for dural repair.
- Its inherent resistance provides advantages in specific neurosurgical indications and anatomical locations.
- This biomaterial expands reconstructive options in pediatric neurosurgery, potentially improving patient outcomes.
Abstract:
The authors report their five-year experience with the use of xenogenic calf pericardium for plastic operations of the cerebral and spinal dura mater which they introduced into neurosurgical practice in 1983. Of 165 grafts they selected 50 which they used in children for the plastic operation of the dura mater above the posterior cranial fossa, above the convexity of the brain and at the skull base. The xenogenic pericardium proved successful and resolved also the shortage of allogenic collagenous tissues (fascia lata, dura mater) used for plastic operations of the dura mater. Moreover, due to its resistance it achieved priority in some indications and localizations. When used, certain conditions must be met to ensure satisfactory incorporation (suitable size, intradural submersion, careful suture).
