| Abstract | 「I. はじめに」門脈圧亢進症では種々の側副血行路の形成がみられ, その中でも食道静脈瘤の存在は, 臨床上患者の予後を左右する上で重要な血行路である. 従来, この部における血流動態を観察する方法として, 経上腸間膜動脈性門脈造影, 経皮経肝門脈造影などが行われているが, これらの方法は侵襲的であるため, より非侵襲的で簡便な観察法が望まれる. 著者らは食道静脈瘤に対する硬化療法前後における血流動態の変化を経皮的に脾穿刺によるRI門脈造影により比較検討したので報告する. 「II. 対象および方法」食道静脈瘤硬化療法前後に本法を施行したのは5例である. 方法は, まず患者体位を検査体位と同じ仰臥位とし, 超音波断層装置を用いて脾門部のレベルで穿刺部位ならびに深さを決定した. ついで局所麻酔を用いず, 23Gカテラン針にてRI(99mTcO4-, 5〜10mCi, 0.5〜1ml)を脾内に注入した. |

| Abstract | [Summary]The hemodynamics of the esophageal varices was studied by injecting small amount of Tc-99m pertechnetate percutaneously into the spleen. The method allowed us to study splenoportal flow in almost physiological way. The study was so far performed in five patients before and right after the sclerotherapy of the esophageal varices. Serial images, obtained from each study, were stored in a computer and later analyzed with a ROI technique. Radioactivity over the area of coronary vein (feeding vein of the esophageal varix) and that of the liver were accumulated. Their ratio was calculated using gamma-fitting method and used as a portal flow ratio. Changes in their esophageal endoscopic findings and serum bile acids were correlated with those in portal flow ratios. There were well-correlated tendencies between radio-activity ratios and scores of endoscopic findings as well as serum bile acids concentration. The method was able to visualize the splenoportal flow with minimal invasiveness, and supplied useful informations of prognosis after the sclerotherapy. |
