Modified USA Dressing Forceps — 25cm American Liver Transplant
The 25cm-labelled Modified USA dressing forceps serves American liver transplant programmes — the high-volume OLT practice at the ~140 American Society of Transplant Surgeons-affiliated centres. American liver-transplant volume is approximately 9000 procedures annually, with median centre volume of 50-70 OLTs per year. The 25cm Modified USA fits the standardised liver-transplant tray that supports these high-volume practices.
The piggyback OLT technique
American liver-transplant programmes have largely adopted the piggyback technique — preserving the recipient inferior vena cava and anastomosing the donor IVC end-to-side, rather than the classical caval-replacement technique. The piggyback approach reduces caval-cross-clamp time and post-reperfusion haemodynamic instability. The 25cm Modified USA forceps handles the piggyback-anastomosis tissue with the precision the technique demands.
The MELD-era allocation
American liver-allocation moved to MELD (Model for End-stage Liver Disease) score in 2002, prioritising sicker patients. This has shifted the transplant-recipient population toward more complex disease, with technical challenges that the 25cm Modified USA forceps’s American-tradition design supports.
