Brain tumors are the most challenging causes of brain deaths due to the lack of pathology results in many cases. It is not uncommon to find a brain tumor in a brain-dead patient with no pathology results or neuroradiology reports available; this would exclude the deceased from organ donation. The mortality that occurs while patients are on transplant wait lists motivated us to find a solution to prevent losing brain-dead patients as potential donors. We present our experiences in autopsy examinations of brain tumors and the results of frozen-section pathology.
We performed autopsy examinations of 8 brain-dead patients who were suspected of having highly malignant brain tumors and in whom there were no pathology or radiology reports available. The autopsy process began at the conclusion of organ retrieval. First, we performed a complete brain dissection; the tumor was then removed with its adjacent brain tissue and sent for examination by an expert pathologist. Organ transplant was deferred until the pathology examination was completed.
Organ transplant was cancelled if the frozen sections revealed a high-grade tumor. For all other results, the transplant was performed. If a medulloblastoma was confirmed, only the heart was transplanted. The duration of the delay for pathologic examination was 30 to 45 minutes. A total of 21 organs were donated that would otherwise have been rejected.
It is worth performing an autopsy and frozen-section pathology examination to prevent losing potential organs from donors with brain tumors who are suspected of having a high-grade neoplasm but have no pathology or neuroradiology reports. This process is simple and has the potential to save lives.
由于在许多情况下缺乏病理结果,脑肿瘤是导致脑死亡最具挑战性的原因。在没有病理结果或神经放射学报告的脑死亡患者中发现脑肿瘤的情况并不少见;这将使死者不符合器官捐赠条件。患者在移植等待名单上时发生的死亡促使我们找到一种解决方案,以防止失去作为潜在捐赠者的脑死亡患者。我们介绍我们在脑肿瘤尸检检查以及冰冻切片病理结果方面的经验。
我们对8名疑似患有高度恶性脑肿瘤且没有病理或放射学报告的脑死亡患者进行了尸检检查。尸检过程在器官获取结束后开始。首先,我们进行了完整的脑部解剖;然后将肿瘤及其相邻脑组织取出,送交给专家病理学家进行检查。器官移植推迟到病理检查完成后进行。
如果冰冻切片显示为高级别肿瘤,则取消器官移植。对于所有其他结果,则进行移植。如果确诊为髓母细胞瘤,则仅移植心脏。病理检查的延迟时间为30至45分钟。总共捐赠了21个器官,否则这些器官将被拒绝。
对疑似患有高级别肿瘤但没有病理或神经放射学报告的脑肿瘤捐赠者进行尸检和冰冻切片病理检查,以防止失去潜在器官是值得的。这个过程很简单,并且有可能挽救生命。
