Abstract「要旨」: 胸部大動脈瘤の治療のためExtra anatomic bypass法を行った11例でバイパス血管および左心機能評価を行った. バイパス血管の評価ではRadionuclide angiography (RNA) とComputed tomography (CT) , Digital subtraction angiography (DSA) で画像診断の比較を行った. バイパス血管の血流については各検査法とも診断できた. CTではバイパス血管の造影, 血栓の描出は鮮明であったが, 大動脈クランプの遮断効果が判定できないことがあり, 一回の造影では腹部大動脈の逆行性血流の評価が困難であった. DSAではバイパス血管は鮮明に造影されたが, 血栓の診断が難しかった. RNAではバイパス血管の評価および腹部大動脈の逆行性血流の判定, 血液プール・シンチグラフィの併用により血栓形成の評価, 心プール・シンチグラフィの併用により術後の左心拡張期機能の低下を判定できた. RNAは術後のバイパスおよび心機能評価に有用であった.

Abstract[Summary] : This study was to evaluate outcome of extra anatomic bypass and left ventricular function at postoperative state by radionuclide angiography (RNA) . Surgical proceduce of extra anatomic bypass (EAB) (bypass from ascending aorta to infrarenal portion of abdominal aorta) was applied to extensive thoracic aneurysm (7 cases) and dissecting ancurysm (4 cases) . Left ventricular function was evaluated by left ventricular ejection fraction (LVEF) as systolic index and first third filling fraction (1/3 FF) , mean first third filling rate (1/3 FRm) as diastolic indices. Outcome of EAB was evaluated as to patency of graft, leakage of aortic clamp, thrombus formation in the sequestraed aneurysm and retrograde blood flow in abdominal aorta from bypass graft. Findings of outcome of EAB by RNA were compared with those of computed tomography (CT) and digital subtraction angiography (DSA) . Result of left ventricular function analysis and outcome of EAB were shown, as follows. Although systolic function of left ventricle was normal, diastolic function was impaired in postoperative patients of EAB. RNA was useful in evaluating not only outcome of EAB but also postoperative left ventricular function.
