中文摘要 | 對於截肢的病人而言,幻肢痛是一項常見的經驗,然而其產生的確切 機轉仍不清楚。本篇報告一位在左肘上截肢後產生幻肢痛的病人,其鎝 -99m-HMPAO腦部單光子射出電腦斷層發現在右頂葉皮質區域明顯的局部血流 的增加,這一個現像顯示大腦皮質可能與幻肢痛的產生有關。至於在幻肢痛的機 轉上,大腦皮質的角色及腦部單光子射出電腦斷層的用途,則有待進一步的研究 來確認。 |
英文摘要 | Phantom limb pain is a common experience for patients who have received amputation. However, the definite mechanism is still not clear. Here, we describe a patient who suffered from phantom limb pain after left above-elbow amputation. The Tc-99m hexamethylpropylene amine oxime (HMPAO) brain single photon emission computed tomography (SPECT) study revealed increased regional cerebral blood flow in the right parietal cortex. This finding may imply the involvement of cerebral cortex in the development of phantom limb pain. Further study is worthwhile to elucidate the utility of SPECT and the role of cortex in phantom limb pain. |
