120例脑死亡法医病理学研究及《环椎后弓切除术式》应用

Forensic Pathological Study of Brain Death in 120 Cases and Application of Posterior Arch-Ectomy (P.A.E) of Atlas

脑死亡的提出是现代医学发展的必然，因为它关系到人的生与死的定义和判定；关系到临床复苏的标准和是否有效；关系到伤病者的死亡何时宣告，临床抢救几时终结；关系到器官移植的开展；关系死亡的哲学、生物学、医学、法律等广范领域。因此，成为现代法医学重要研究课题之一。

1. Forensic autopsies in 120 cases died from primary intracranial damage were made.2. These cases were divided into the part of primary brain death becauof the antemortem clinical signs of brain (come apnea and the other functions Less of brain) prior to the signs of heart.3. Using the method 《P.A.E》 created by me, it was found that there were 112 cases (93.3%) had herniations of foramen magnam including cerebellar herniation in 71 cases (59.2%) and cerebellar tonsillar medullary oblongata rerniation in 41 cases (34.2%). In which 99 cases (82.5%) had liquefications of the cerebellar tonsillar herniations; 27 cases (22.5%) were found that the fragments of cerebellar tonsillar tissue were fallen into spinal space and 3 cases (2.5%) implanted the spinal cords;4. The one of the distinetive findings in this study was the growth of implanted cerebellar tonsillar tissue in the spinal cords.5. On the Occurence and development of brain death in this series, except Primary intercrinial damages the secondary neuropathological changes especiall the anoxic and ischemic necrosis of cerebral cortex cerebellar cortex and brain stem were important too.
