A variation of the technique of transfemoral pulmonary arteriography.

A variation of the transfemoral pulmonary artery catheterization technique utilizes a commercially available pigtail catheter with high torque control. A single 90 degree curve is added to this catheter prior to the examination. This resulted in successful catheterization of the right and left pulmonary arteries. No catheter tip deflector system or other special equipment was needed. There have been no complications.
