Reduction of the size of the aortopulmonary shunt.

Best answers
Can anyone help? I can't find a code for this.

A midline was performed

using reoperative techniques. After the cardiac structures were

carefully dissected, I dissected out the aortopulmonary shunt

adequately and went around the shunt and mobilized it. At this point

I took a silastic patch and cut out a 4.5 to 5 mm wide band of

silastic band and then I tailored this to a circumference of

approximately a 3 mm Hegar dilator circumferential. This was

measured and was marked and I wrapped this around the proximal part

of the shunt and then placed 6-0 Prolene sutures through it using a 5

mm shunt to a 2 mm shunt. We this the diastolic pressures went up by

approximately 8 to 10 mmHg and the saturations stabilized down into

the 70s.
