Case Reports
[Autogenous pericardial patch augmentation of the anastomotic orifice of Blalock-Taussig shunt].
Our recent experiences of the autogenous pericardial patch augmentation of Blalock-Taussig anastomotic orifice are reported. In Case 1, the direct suture between the left subclavian artery and the left pulmonary artery was difficult on the anterior wall because of the shortness of the left subclavian artery. Therefore, a piece of the patient's own pericardium was excised and sutured anteriorly between the two vessels by interrupted 7-0 polypropylene sutures. ⋯ In Case 3, the same operation as in Case 2 was performed. A 6 months postoperative angiogram showed no stenosis or distortion of either the subclavian or the pulmonary artery. Although it is premature to draw any conclusion, the use of the autogenous pericardium may be indicated to widen the anastomotic orifice of Blalock-Taussig shunt without sacrificing the length of the subclavian artery even in small infants or neonates.
