僧帽弁位生体弁置換術後早期に, 一過性の狭窄性の機能不全を生じた症例を経験した. 症例は62歳の男性. 僧帽弁閉鎖不全症による心不全をきたし手術を希望した. 手術中の所見で, 僧帽弁は, 前後尖の腱索が断裂し, 前後尖とも変形をきたしており修復しえず, 29mm Hancock II弁による僧帽弁置換術が行われた. 術後2週で行われた心臓カテーテル検査および経食道心臓超音波検査で, 僧帽弁の逆流は認めなかったが, 3弁尖のうち1弁尖が閉鎖位で固定されていて開放せず, 軽度の狭窄性の機能不全が認められた. 発生原因が不明であったが, 外来で経過をみていると, 術後6月の経食道心臓超音波検査で, 3弁尖とも開閉しており, 生体弁・心機能とも異常ないと考えられた. 術後2年の現在も健在である.

Successful repair of a distal aortic arch aneurysm without aortic cross-clamping was carried out in a 74-year-old man, using a combination of special separate cerebral perfusion and retrograde coronary perfusion, termed non-clamping selective cerebral perfusion. We believe that satisfactory results following aortic arch surgery in elderly patients can only be achieved through the prevention of emboli derived from an aortic cross-clamping site, and shortened ischemic time of the vital organs.
