Abstract「要旨」動脈管開存症 (PDA) 5症例についてradioisotopic angiocardiography (RI-ACG) の動態画像および動態曲線所見を調べ, 本疾患に特徴的なRI-ACG所見を検索した. また, RI-ACG所見を心血管造影や心カテーテルなど他検査の所見と比較し, 本疾患の診断ならびに病態把握に当たってのRI-ACGの臨床的意義を検討した. 動態画像および曲線は共に本疾患に特徴的な所見をいくつか示し, これら所見は心内左右短絡疾患との鑑別に有用と考えられた. 中でも, 動態画像所見として肺動脈稀釈像および短絡像が, また動態曲線所見として肺および左心室曲線の初回循環波下降脚の短絡波が特徴的であった. 一方, 本検査はPDAに合併した肺高血圧症や心不全の診断にも有用な所見を示した. また, 本検査は, 連続性雑音の間歇的に消失した症例において, その血流動態の急激な変化を簡便かつ的確に検出することができた.

Abstract[Summary] : Dynamic images and curves obtained from radioisotopic angiocardiography (RI-ACG) using video recording system were studied in 5 patients with patent ductus arteriosus (PDA) , to disclose any characteristic findings of PDA on this radioisotopic examination. And, the examination was evaluated with referance to diagnosis and assessment of status of PDA, comparing with other radiological examinations including angiocardiography and catheterizatlon. Both the dynamic images and the dynamic curves of RI-ACG showed some characteristic findings of PDA, which was considered to be valuable to differentiate the intracardiac left to right shunt in atrial or ventricular septal defect. It was very characteristic of PDA that dynamic images showed regional dilution and recirculation patterns in the region of the main pulmonary artery to its periphery, and dynamic curves presented shunt waves on the descending limbs of the first circulation waves of both the pulmonary and the left ventricular region of interest. The Degrees of appearance of these characteristic findings showed a tendency to well correlate with the value of the left to right shunt fraction calculated by cathetelization technique. On the other hand, RI-ACG showed useful findings to diagnose pulmonary hypertension or heart failure associated with PDA. And, RI-ACG was very useful to detect an abrupt change of the central circulation dynamics in a patient with PDA, in whom continuous murmur characteristic of PDA desappeared intermittently.
