Identifying Blalock-Taussig shunts using a Silastic band.

Abstract

Placement of an encircling Silastic band around Blalock-Taussig shunts facilitates identification and ligation of the shunt at the time of corrective operation. This technique of "shunt banding" is particularly useful for left-sided shunts, both native and modified. We have noted no complications, specifically shunt constriction. Placement of the band adds minimal operative time during shunt placement and substantially lessens the time and amount of dissection required during subsequent procedures.
