Axillary vein approach for pulmonic valvuloplasty in infants with iliac vein obstruction.

Repeated pulmonic balloon valvuloplasty from the axillary vein was performed in two infants with initial transvalvular gradients of 131 and 162 mm Hg. The first angioplasty was performed through the femoral vein and improved the valve gradient in both patients. Because of obstruction of the iliac system the axillary vein approach was used for the second angioplasty. The transaxillary pulmonic valvuloplasty decreased the gradient to acceptable levels, and no complications were noticed. The axillary vein approach can be the alternative to the femoral one in cases with obstructed iliac system or interrupted inferior vena cava.
