"Bail-out" stenting for acute obstruction of a modified Blalock-Taussig shunt following selective angiography.
A 3-year-old boy developed acute obstruction of a left modified Blalock-Taussig shunt following selective power injection of contrast in the shunt. Balloon dilation was ineffective due to rapid recoil of the narrowed segment, but implantation of a stent effectively abolished the obstruction. The obstruction itself may have been produced by an intimal flap caused by the power injection.
