  • Title: Cardiac catheterization in infants through a venous cutdown sheath.
    Author: Henry GW, Harned HS.
    Journal: Cathet Cardiovasc Diagn; 1981; 7(2):209-12. PubMed ID: 7296669.
    Abstract:
    When percutaneous vascular access for cardiac catheterization of small infants fails, necessitating a cutdown approach, we cannulate the isolated vein (usually the great saphenous vein) with a guidewire, dilator, and sheath with subsequent introduction of the catheter through the indwelling sheath. We have used this technique in sixty-one infants without complications and recommend this modified sheath approach because of the following advantages: ease of introduction of the introducer set and catheter, the ability to change catheters quickly, elimination of distal vascular spasm, reduction of vascular trauma induced by catheter manipulation, prevention of backflow bleeding at the catheter entry site, and possible reduction of catheterization time.
