Abstract「要旨」腎動脈分岐部をこえて解離が認められた腹部大動脈瘤患者15例に施行した腎動態シンチグラフィにつき, 腎動脈侵襲との関係を中心にretrospectiveに分析した. 血流相イメージと分腎機能から所見は3つの型に分類された. すなわち, A型 : 血流, 分腎機能ともに左右差を認めないもの, B型 : 血流, 分腎機能ともに1側で低下を認めるもの, C型 : 血流相で1側の血流のおくれを認めるが, 分腎機能に左右差を認めないものである. A型, B型, C型を呈する症例は, それぞれ, 3例, 6例, 6例であった. A型の全例とB型の3例では, 両側とも真腔から腎動脈へ血流が供給されていた. B型の残りの2例では1側の腎動脈が閉塞し, 1例では偽腔から血流を供給される側の腎に梗塞とおもわれる変形がみられた. 一方, 血流と分腎機能の所見に解離を認めるC型の所見を呈する1例では, すべて, 血流のおくれを認める側の腎動脈の血流が偽腔より供給されていた. この所見は, 真腔に比し, 血流のおくれる偽腔の血行動態を反映した所見と思われ, 1側の腎血流が偽腔から供給される場合の特徴的な所見と考えられた.

Abstract[Summary] Dynamic renal scintigraphy on 15 patients of dissecting aneurysm of abdominal aorta extending below the renal arteries were retrospectively studied. The results were reviewed and classified into 3 types according to perfusion images and parenchymal tissue uptake : Type A : symmetric perfusion and parenchymal tissue uptake, Type B : asymmetrical perfusion and parenchymal tissue uptake, Type C : Delayed perfusion of one kidney and symmetric parenchymal tissue uptake. The number of patients who showed Type A, Type B, and Type C were 3 cases, 6 cases, and 6 cases, respectively. In all Type A and 3 of Type B, perfusion of bilateral renal arteries was mainly from true lumen. In the remaining 3 cases of Type B, 2 had one renal artery obstructed with thrombus ; 1 had a deformity of one kidney (the blood supply was mainely from a false lumen), suggestive of renal infarction. On the other hand, in all 6 Type C cases, the renal artery where perfusion was delayed was apparently supplied from false lumen. It is suggested in this retrospective study that the findings in Type C, where delayed perfusion of one kidney and symmetric parenchymal tissue uptake were found, were due to the presence of delayed flow through the false lumen ; and therefore, specific to cases where the main blood supply of one renal artery from false lumen.
