Abstract「要旨」冠状動脈バイパス手術(CABG)における内胸動脈(ITA), および下腹壁動脈(IEA)の血流増加を目的として下腹壁動静脈シャント造設術を行った. 実験イヌ6頭を用いて, IEA起始部を大腿静脈と端側吻合した. 1ヶ月ごとに, シャント造設側のITA造影を行い, 4ヶ月間追跡した. ITA中央部平均径はシャント造設時の1.84mmから1ヶ月後には2.06mm(P<0.05), 4ヶ月後には2.5mmへと有意に増加した(P<0.01). IEAはシャント造設直後わずかに造影されるのみであったが, 3ヶ月後には大腿静脈への造影剤の流入が確認された. IEA内径には有意の変化はなかった. 下腹壁動静脈シャントによりITAの内径拡大とIEAの血流増加が得られたことから, この方法は動脈グラフトによるCABGの適応拡大に寄与すると考えられた.

AbstractAlthongh the use of arterial graft is preferable in CABG, the internal thoracic artery (ITA), inferior epigastric artery (IEA), gastroepiploic artery (GEA) or radial artery (RA) is not long enough for complete revasculalization. To increase flow and size of ITA and IEA as an arterial graft for use in CABG, shunting the IEA to the common femoral vein making an arterio-venous fistula was experimentally undertaken using beagle dogs. Arteriography of the ITA and IEA was followed for 4 months. The diameter of ITA increased significantly from 1.84±0.05mm at the shunt operation to 2.06±0.05mm (p<0.05) after 1 month and 2.5±0.1mm (p<0.01) after 4 months. But no significant increase in diameter was observed in IEA. Although IEA was not visualized at the shunt operation, a clear visualization of IEA with efflux to the femoral vein was obtained 3 months after the shunt operation. Increased diameter of the ITA and flow of IEA suggested the clinical application of IEA shunting to the femoral vein is promissing for clinical use as a long arterial graft.
