Percutaneous translumbar cardiac catheterization and central venous line insertion: An alternative approach in children with congenital heart disease

Children with congenital heart disease present major problems with venous access, eliminating conventional routes for cardiac catheterization. Although the transhepatic approach has recently gained popularity, we describe here an alternative approach using percutaneous translumbar approach for cardiac catheterization and/or in-dwelling central line insertion in three children with congenital heart disease. Diagnostic hemodynamic studies, transcatheter delivery of an intravascular stent for left pulmonary artery (LPA) stenosis, and chronic central Venous line insertion were performed using this technique. Disadvantages include interventionalist's unfamiliarity with technique, awkward patient positioning, technically more difficult than transhepatic, and potential injury to kidney and bower. Advantages include avoidance of vascular-rich hepatic parenchyma, thus reducing risk of hemorrhage; providing an alternative where transhepatic entry may be contraindicated; avoidance of bile duct, portal vein, and hepatic artery injury; and providing another alternative for not only transvenous, but also transarterial access that may be required for intravascular aortic stent delivery. The interventional radiologist should be utilized as a valuable resource to the cardiologist to help teach and supervise this technique in selected infants and children with limited vascular access.
