We previously presented a cardiopulmonary bypass (CPB) method with blood delivery
via femoral artery cannulation for pediatric aortic arch repair operations using the
Radifocus Introducer sheath. However, the flow rate with the Radifocus Introducer
sheath is limited by accessory parts with the same structure having a smaller inner
diameter among different sizes, rather than the sheath body. Therefore, we further
devised a combination of the JELCO IV catheter, an extension tube, and a three-way
stopcock with a larger opening to obtain more flow rate keeping the CPB circuit pressure
significantly lower than when using the Radifocus Introducer sheath successfully.
