| Abstract | 「要旨」キーンベック病31例33関節に, 3フェーズ骨シンチグラフィを施行した. うち19例は治療経過の観察を目的とした. 動脈相と静脈相に分けたことで, 血流の解析が容易となった. 経過良好例には, 血管像で尺骨動脈の血流亢進と月状骨への灌流増加が見られ, 病状の回復には尺骨動脈血流が重要であることが示唆された. また術前例の病期診断には月状骨周囲の集積の多寡が重要で, 進行例ほど集積が亢進していた. このため後期像だけでも病期や病状を判定できたが, 情報量ではプール像には劣った. すなわちプール像は, 病巣の血液量や修復能等現状に即した画像を提供するので, 病状の分析や治療効果の判定にも有用であり, 汎用されるべき検査法である. 特に月状骨に限局した集積は月状骨への灌流増加と相俟って, 治癒の期待できる望ましい所見であった. |

| Abstract | [Summary]Thirty-three joints in 31 patients of Kienbock disease were evaluated with three-phase bone scintigraphy. Follow-up studies were performed in 19 cases of them. The patients with increased ulnar blood flow on arterial phase and ample perfusion on venous phase in angiograms showed good clinical prognosis. This ample ulnar blood flow and perfusion might be essential for the recovery of this disease. Although staging was possible using static images alone, blood pool images provided more information about the present condition of lesions, such as hyperemic state and remodeling reactions. Blood pool image was indispensable for staging and analyzing lesions and evaluating Post-operative course. Increased lunate perfusion in venous phase of angiograms and localized lunate uptake in blood pool images were the favorable signs, which were shown in most cases with good prognosis. It is concluded that three-phase bone scintigraphy gives useful informations for evaluating Kienbock disease which can not be obtained by conventional bone scintigraphy. |
