Pulmonary artery catheter placement with two-dimensional echocardiographic guidance: a technique applicable in critically ill neonates.

In nine critically ill neonates with persistent fetal circulation, femoral venous catheters were inserted at the bedside to initiate treatment and provide venous access. After femoral vein puncture or cutdown, a 5-F sheath was placed in the inferior vena cava through the femoral vein. With use of two-dimensional echocardiographic guidance, a 5-F balloon angiographic catheter was advanced through the inferior vena cava into the right atrium and subsequently manipulated through the tricuspid valve and into the main pulmonary artery. No major complications were attributable to the procedure. When performed by a pediatric cardiologist, this technique is as safe as umbilical catheter placement.
