血液希釈性自己輸血下に摘出した若年性血管線維腫の1症例

Juvenile Angiofibroma Extirpated under Hemodiluted Autotransfusion

はじめに

　鼻咽腔血管線維腫は，臨床的には年齢・性・現病歴および局所所見より比較的容易に診断されるが，手術に際して大量の出血が予想されるため，術前に腫瘍の進展範囲を充分に把握し，術前処置や摘出方法などを検討・工夫する必要がある。

　今回我々は，術前にホルモン療法を施行し，麻酔科医の協力により血液希釈性自己輸血（hemo—dylutional autotransfusion：HAT）下で摘出した症例を経験したので若干の文献的考察を加えて報告する。

A 15-year-old boy with a chief complaint of repeated left nasal bleeding had a diagnosis of nasopharyngeal fibroma with abundant blood vessels. The tumor was extirpated under general anesthesia after preoperative hormonal therapy. Although a total amout of bleeding during opera-tion reached 1,650ml, no homologous blood was transfused at all but autotransfusion of 1,200ml.

Autotransfusion was therefore considered as use-ful for prevention of infections as serum hepatitis, AIDS, ATL.
