| Abstract | 「要旨」 肺血流シンチグラフィより求めた灌流欠損度 (%PD) と心プールシンチグラフィより算出した右室駆出率 (RVEF) にて肺血栓塞栓症 (pulmonary thromboembolism : PTE) の重症度判定を行った. 対象は肺血流シンチグラフィと心プールシンチグラフィを1週間以内に施行した肺血栓塞栓症36症例である. このうち27例では経過観察のため再度の肺血流シンチグラフィを行った. RVEF正常群 (>38% : n=15) , 低下群 (≦38% : n=12) で抗凝固療法前後の肺シンチ上の灌流欠損 (PD) の差ΔPD (+ : 改善, - : 悪化) は, それぞれ19.40±15.58 (%) , 0.00±3.91 (%) であり, RVEF正常群にて治療の奏功を予測しえた. また%PD<40の26例, %PD≧40の7例で3年間の経過観察中の死亡率はそれぞれ3.8%, 42.9%であった. これらの結果よりPTEにおいて重症度閾値 (RVEF=38%, %PD=40) を用いた非観血的な病型分類は臨床的重症度を反映し, 予後の評価に有用であった. |

| Abstract | [Summary] In 36 cases, severity of pulmonary thromboembolism (PTE) were determined with extent of perfusion defect (%PD) from pulmonary perfusion scintigraphy combined right ventricular ejection fraction (RVEF) from radionuclide angiocardiography. In 27 cases, follow-up scintigraphy was also done. After medical therapy, ΔPD (=initial %PD-follow up %PD) was significant improved in patients with normal RVEF (>38%) (19.40+-15.58% : n=15) than that in those with reduced RVEF (<=38%) (0.00+-3.9%) . In follow-up studies, patients with larger %PD (>=40) showed poor prognosis than those with moderate or less %PD (<40) . In conclusion, these both non-invasive indicators were proved to be usefull for the evaluation not only the clinical severity but the prognosis of pulmonary thromboembolism. |
