◆要旨:腹腔鏡下胆囊摘出術を施行中に中肝静脈が胆囊床に露出した症例を経験し,MRI画像上で両者が接していたため,171例のMRIで中肝静脈と胆囊間の距離を測定した.両者の距離は冠状断での測定では100例(58.5%)で可能であり,水平断ではほとんど不可能であった.測定結果は1~26mmの範囲であり,距離の平均は10.1mmで,2mm以内は3%であった.同様な距離測定の報告は,カラードプラUSと血管造影CTによる測定であり,MRIを用いた検討は筆者らが初めてと思われる.MRIによる測定は描出率では劣るものの,造影や特殊な技術は不要であり,客観的でretrospectiveな検討が可能なので,有用であると考えられた.
We measured the distance between the middle hepatic vein(MHV)and the gall bladder using magnetic resonance imaging(MRI)in 171 cases because we encountered a rare case in which the MHV was exposed to the gall bladder bed.
Distance could be measured in 100 cases(58.5%)on only coronal section. Measured distance ranged from 1 to 26 mm(mean 10.1 mm), 3 cases(3%)were the less than 2 mm . In other reports, it was measured by color Doppler ultrasound or contrast enhanced CT, so our report using MRI was thought to be the first.
MRI shows a poor success rate at measurement of distance, but enhancement and special technique are not necessary. This method was thought to be effective because objective and retrospective examination could be done.
