Intraoperative Graft Verification in Renal Transplants
The success of an arterial reconstruction is dependent on multiple factors, including patient selection, quality of the vessels, type of vascular conduit employed, and the surgical technique adopted. Transit time flow measurement is a technique that is now the standard of care for immediate graft patency verification following coronary artery bypass graft surgery. Read more...
Liver and Systemic Hemodynamics in Children With Cirrhosis: Impact on the Surgical Management in Pediatric Living Donor Liver Transplantation
Cirrhosis in adults is associated with modifications of systemic and liver hemodynamics, whereas little is known about the pediatric population. The aim of this work was to investigate whether alterations of hepatic and systemic hemodynamics were correlated with cirrhosis severity in children. The impact of hemodynamic findings on surgical management in pediatric living donor liver transplantation (LT) was evaluated. Liver and systemic hemodynamics were studied prospectively in 52 children (median age, 1 year; 33 with biliary atresia [BA]). The hemodynamics of native liver were studied preoperatively by Doppler ultrasound and intraoperatively using invasive flowmetry. Portosystemic gradient was invasively measured. Read more...
Intraoperative Flow Measurement of Native Liver and Allograft During Orthotopic Liver Transplantation in Children
Hepatic hemodynamic changes during orthotopic liver transplantation (OLT) in children have not yet been studied. We measured intraoperative portal vein flow (PVF) and hepatic arterial flow (HAF) (mL/min) in 53 children and 58 grafts during OLT.
Flows were measured in the native organ and in the allograft. In the native liver, PVF and HAF are similar; after transplantation they return to the physiological situation. Read more...
Too Much, Too Little, or Just Right? The Importance of Allograft Portal Flow in Deceased Donor Liver Transplantation
While portal flow (PF) plays an important role in determining graft outcomes in living donor liver transplantation, its impact in deceased donor liver transplantation (DDLT) is unclear. The aim of this study was to investigate the correlations between graft PF and graft outcomes in DDLT.
Methods: We retrospectively investigated 1001 patients who underwent DDLT between January 2007 and June 2017 at our institution. The patients were divided into 3 groups according to hazard ratio for 1-year graft loss at each PF value, which was standardized with graft weight. Graft and recipient outcomes were compared between the groups.
