| Abstract | 「要旨」 肝硬変17例を対象に内視鏡的食道静脈瘤硬化療法(EIS)前後における門脈側副血行路の変化をSingle Photon Emission CT(SPECT)を用いて検討した. SPECTは99mTcO4-20mCiの静注にて99mTc-in vivo赤血球標識後, 楕円軌道で360°を64方向から1方向30秒でデータを収集した. 17例中14例にcoronary vein, 3例にshort gastric veinの描出がみられた. coronary veinが描出された14例中8例, short gastric veinが描出された3例中1例にEIS後coronary veinないしはshort gastric vein領域の血液プールの消失または減少がみられた. EIS後の食道静脈瘤の経過観察に際し, 門脈側副血行路の変化を非侵襲的に観察しえる方法としてSPECTは有用な方法であると考えられた. |

| Abstract | [Summary] The changes in portal collaterals before and after Endoscopic Injection Sclerotherapy (EIS) for esophageal varices were studied by Single Photon Emission CT (SPECT). SPECT was performed for the intra-abdominal blood pool with 99mTc autologous red blood cells (RBC) in 17 patients with liver cirrhosis before and after EIS. Twenty mCi of 99mTc-RBC labeled by in vivo technique were administered intra-venously and tomographic imaging of the intra-abdominal vascular blood pool was performed as follows. For each subjects, 64 views were obtained over 360° of elliptic rotation at 30 seconds per view. In 15 of 17 patients, blood pool images over coronary vein and/or short gastric vein area were clearly demonstrated on coronary images. In 9 of 15 patients, the pool of coronary vein or short gastric vein was disappeared or decreased after EIS. It is considered that intra-abdominal blood pool SPECT study is clinically useful for following up of hemodynamics of portal collaterals before and after EIS. |
