We use Flowprobes to evaluate flows in the hepatic artery and portal vein in the setting of living donor liver transplantation. This formal process allows us to evaluate the impact of flows on eventual graft function and correlate with risk factors for graft failure." Emond, J, MD, Chief of Transplantation, Columbia Presbyterian Medical Center, Co-chair, A2ALL Study.

Life-saving transplant surgeries challenge a transplant surgical team to perform at their highest level. During these high stake surgeries, intraoperative blood flow measurements provide a quick, quantitative assessment of anastomotic integrity and blood flow that either confirms a clinical impression or alerts the team to potential problems while they still can be more easily addressed.

Orthotopic liver transplantation, in particular, presents a unique opportunity for intraoperative flow measurements. Measurements are incorporated into the protocol for the multicenter Adult-to-Adult Living Donor Liver Transplantation (A2ALL) Study. Since simple visualization of a pink-to-red reperfused liver doesn’t ensure that both the hepatic artery and portal vein are each functioning, simultaneous hepatic/portal measurements provide an essential quality assurance.

In addition to checking the quality of anastomoses in liver, renal, pancreatic, lung and heart transplant surgeries, intraoperative measurements also identify potential kinking of conduits, particularly veins, and are useful in identifying donor-to-recipient mismatches. No other flow technology produces flow data as quickly, accurately and non-intrusively during transplant surgery as Transonic intraoperative flow measurements.

Benefits are:

  • Reduce allograft risk of failure
  • Identify impaired blood flow before closure
  • Document restored flow
