Abstract:
Perinatal autopsies present forensic patholgists with a variety of challenges, not the least of which involves the removal and examination of very small and sometimes fragile organs. Removal of the immature brain can be particularly troublesome. Even if great care is taken during brain removal, one is often left with no more than a semifluid amorphous mass of softened tissue by the time the brain is ready to be fixed in formalin. We describe a method of perinatal brain removal which helps to preserve brain shape and integrity. By removing the brain while the head (and body) is totally immersed in water, we find that the brain is easier to remove and less apt to destruction. Subsequent fixation in formalin results in well-preserved, intact specimens, allowing for optimal examination and sectioning.
Insights
Forensic pathologists can preserve fragile perinatal brains during autopsy. A novel water immersion technique facilitates easier removal and fixation, ensuring intact specimens for examination.
Area of Science:
- Forensic Pathology
- Pediatric Pathology
- Neuropathology
Background:
- Perinatal autopsies pose challenges due to small, fragile organs.
- Immature brain removal is particularly difficult, often resulting in tissue destruction.
Purpose of the Study:
- To describe a method for preserving perinatal brain integrity during autopsy.
- To improve the quality of specimens for examination and sectioning.
Main Methods:
- A novel technique involving total immersion of the head and body in water during brain removal.
- Subsequent fixation of the brain in formalin.
Main Results:
- The water immersion method simplifies brain removal, reducing tissue damage.
- Intact, well-preserved brain specimens are obtained, suitable for detailed examination.
Conclusions:
- This water immersion technique is effective for preserving perinatal brain shape and integrity.
- It enhances the ability to perform optimal examination and sectioning of perinatal brains.
