Cardiac catheterization in infants through a venous cutdown sheath

Area of Science:

• Pediatric Cardiology
• Vascular Surgery
• Interventional Radiology

Background:

• Percutaneous vascular access for cardiac catheterization in infants can be challenging and may fail.
• Failure necessitates a cutdown approach, often involving direct cannulation of a vein like the great saphenous vein.

Purpose of the Study:

• To describe and evaluate a modified sheath technique for infant cardiac catheterization following failed percutaneous access.
• To highlight the advantages of this modified sheath approach in pediatric cardiac procedures.

Main Methods:

• A cutdown approach was used to cannulate the isolated great saphenous vein in small infants.
• A guidewire, dilator, and sheath were introduced, followed by catheter insertion through the indwelling sheath.
• The technique was applied to sixty-one infants.

Main Results:

• The modified sheath technique was successfully employed in sixty-one infants without any reported complications.
• Key advantages observed include ease of introducer and catheter insertion, rapid catheter exchanges, and elimination of distal vascular spasm.

Conclusions:

• The modified sheath approach is a safe and effective alternative for infant cardiac catheterization when percutaneous access fails.
• This technique offers benefits such as reduced vascular trauma, prevention of bleeding, and potentially shorter procedure times.
