目的:脊髄髄内腫瘍の神経症状の推移を調査すること.対象:手術治療を行い詳細な神経学的所見を把握できた37例.方法:術前・術直後・最終観察時の3時点で,下肢機能,感覚機能,膀胱機能の改善・不変・悪化を調査した.結果:術直後には約80%に悪化が見られたが,そのうち約90%は最終観察時までに改善傾向であった.術前と最終観察時との比較では約65%で悪化していた.術前の機能がよい状態で手術を行ったほうが最終成績がよかった.結語:脊髄髄内腫瘍は神経症状が悪化することが多く,早い段階での手術が望ましいと考える.
Purpose:We studied postoperative changes in neurological symptoms of intramedullary spinal cord tumors (IMSCT). Objective:Subjects were 37 patients with IMSCT who has been treated surgically. Methods:Lower leg, sensory, and urinary functions were studied preoperatively, immediately after surgery, and at final follow-up. Results:Although 80% of patients deteriorated neurologically immediately after surgery, 90% improved by final follow-up. Compared to preoperative symptoms, final symptoms deteriorated in 65%. Patients in good preoperative stage had good outcomes. Conclusion:Most cases of neurological symptoms are likely to deteriorate sooner or later, so we recommend early surgery.
