In right lobe living donor liver transplantation (ALDLT), reconstruction of middle hepatic vein (MHV) tributaries is often necessary to avoid severe graft congestion. From March 2001, we performed 36 right lobe ALDLT (segments 5, 6, 7, and 8) without MHV and one pediatric transplant (segments 2 and 3). In the presence of MHV tributaries larger than 5 mm, we intraoperatively evaluated the need for reconstruction. At a mean follow-up of 848 days (range = 8-2412), 33/37 transplanted patients are alive with overall patient and graft survivals of 89.2% and 83.8%, respectively. Large MHV tributaries (>5 mm) were present in 10 cases, and inferior right hepatic veins (IRHV) draining segment 6 in 11 cases. In 10 cases, we performed an end-to-side anastomosis between the IRHV and the side of the recipient vena cava. In three cases, the MHV tributaries were end-to-end anastomosed to the stump of the recipient MHV. In all other cases, the vein tributaries were not reconstructed. A computed tomography scan performed from 1 to 3 months after surgery did not show any congested area in the liver parenchyma. In our experience, reconstruction of the MHV tributaries was not always necessary when graft-to-recipient weight ratio is >0.8. Pre- and intraoperative evaluation of the segmental branches of the hepatic vein is crucial to decide about reconstructing these collaterals.

Abstract

In right lobe living donor liver transplantation (ALDLT), reconstruction of middle hepatic vein (MHV) tributaries is often necessary to avoid severe graft congestion. From March 2001, we performed 36 right lobe ALDLT (segments 5, 6, 7, and 8) without MHV and one pediatric transplant (segments 2 and 3). In the presence of MHV tributaries larger than 5 mm, we intraoperatively evaluated the need for reconstruction. At a mean follow-up of 848 days (range = 8-2412), 33/37 transplanted patients are alive with overall patient and graft survivals of 89.2% and 83.8%, respectively. Large MHV tributaries (>5 mm) were present in 10 cases, and inferior right hepatic veins (IRHV) draining segment 6 in 11 cases. In 10 cases, we performed an end-to-side anastomosis between the IRHV and the side of the recipient vena cava. In three cases, the MHV tributaries were end-to-end anastomosed to the stump of the recipient MHV. In all other cases, the vein tributaries were not reconstructed. A computed tomography scan performed from 1 to 3 months after surgery did not show any congested area in the liver parenchyma. In our experience, reconstruction of the MHV tributaries was not always necessary when graft-to-recipient weight ratio is >0.8. Pre- and intraoperative evaluation of the segmental branches of the hepatic vein is crucial to decide about reconstructing these collaterals. Anastomosis of V5 or V8 to the stump of the recipient MHV reduces the number of vascular anastomosis and maintains a physiological angle between these collaterals and the caval vein. © 2008 Elsevier Inc.
