Abstract近時, 特発性門脈高圧症そのほかの脾腫性疾患に総脾血流量の著明な増加のあることが知られてきた. かかる事実は臨床的に希有ガスクリアランス法による単位重量当りの脾血流量測定が行なわれ, 脾実質重量の計測により総脾血流量が算出されて明らかにされたものである. したがって脾実質重量を生体外より推定することが, 臨床的にきわめて重要な意義を持つようになってきた. 従来から, 腹部単純X線の脾臓影を利用して, 生体外から脾重量を推定するいろいろな方法が案出されている. しかしかかる方法には幾多の難点があり, 脾シンチグラム法には従来のX線法の欠点を補いうる幾つかの長所がある. われわれは脾シンチグラム法を用い, 脾シンチグラム像の断面積と摘出脾重量とを対比させて脾実質重量を推定する方法を検討し, その臨床的応用を試みた. 「対象および方法」1)対象:特発性門脈高圧症(IPH) 8例について, 摘脾前に脾シンチスキャニングを施行した.

Abstract[Summary] This study was based on the 8 operated spleens of idiopathic portal hypertension. The scintiscanning was performed by 203Hg-MHP method before splenectomy. The cross. sectional areas of the spleen taken by the scan were measured by planimater. After the spleen was removed py operation, blood of the spleen was completely washed out by perfusion of saline, The spleen was weighed after saline was removed from the spleen. The spleen weights thus obtained were plotted against the scan "surface areas" of the corresponding spleen on the log-log paper, A linear relationship was found to exist between these values. The straight lines, which were obtained by the method of least squares, were as followed. Log W=1.66 log S-1.03 or W=0.093 S1.66 on the sagital plane (I) log W=1.34 log S-0.18 or W=0.066 S1.31 on the frontal plane (II) (W: the spleen weight S: scan "surface area") The spleen weights were plotted against the volumes calculated from the equation S.F/L on the section paper and the curve indicated a straight line relation. ship. This straight line, which was obtained by the method of least squares was as followed: W=0.413 V-60.0 (III) (W: the spleen weight, V: the calculated splenic volume, S: scan "surface area" of sagital plane, F: scan "surface area" of frontal Plane, L: vertical height of the spleen) There is good correlation between the estimated spleen weights derived from the above equation and the operated weights, correlation coefficients of (I), (II) and (III) being 0.934, 0.879 and 0.925, respectively. Estimation of the spleen weight is necessary to the calculation of the total splenic blood flow based on the radioactive rare gas clearance method, whtch is one of our important indexes to determine the indication of splenectomy in portal hypertension.
