    ABSTRACT: Certain complexities, such as extensive vena caval injury, unexpected dense adhesions between liver and retrohepatic vena cava, and liver tumor abutting retrohepatic vena cava, sometimes warrant resection of vena cava during living-donor liver transplantation. Because the donor graft is devoid of vena cava, reconstruction of the retrohepatic cava is required, which can be done with the use of either a cryopreserved venous graft or an artificial conduit. With only a few published reports, the experience in vena cava reconstruction with the use of expanded polytetrafluoroethylene (ePTFE) during living-donor liver transplantation remains limited. We present our experience of 4 patients who successfully underwent vena caval resection during liver transplantation for various indications, which was subsequently reconstructed with the use of ePTFE grafts. All of these patients except 1 recovered well without any undue complications, such as thrombosis or outflow inadequacies, thus proving this extensive surgical treatment to be a successful and life-saving procedure, though meticulous skills are prerequisite.

    ABSTRACT: To present our experience with simultaneous living donor liver and kidney (SLK) transplantation from two different living donors. We performed five SLK transplantations from two different living donors from November 2006 to December 2010. Four patients were males and one, female. Their age range was 47 to 66 years (mean, 55 years). The primary liver diseases included hepatitis B virus (n=2), alcoholic liver cirrhosis (n=2), cryptogenic liver disease (n=1), and hepatitis C virus with hepatocellular carcinoma (n=1). All five patients had chronic renal failure: four were on hemodialysis (H/D) and one on chronic ambulatory peritoneal dialysis for 1 to 20 years. Liver implantation was performed first, followed by kidney transplantation. The liver and kidney teams worked closely to shorten the ischemia time. All surgical procedures were performed uneventfully and all recipients and donors survived the operations. Good liver graft function was noted in all five patients. The patient with both anti-T- and anti-B-cell positive crossmatch tests developed hyperacute rejection of the kidney graft requiring its immediate removal. This patient was maintained on regular H/D afterward. The other four patients displayed good renal function. No evidence of severe acute rejection was noted during the follow-up period (range, 9-55 months) among patients treated with tacrolimus-based immunosuppression. We suggest that SLK transplantation be performed with organs from two different instead of a single live donor.

    ABSTRACT: Venous congestion of segments V and VIII of the graft is observed frequently in right-lobe living donor liver transplants (LDLT) without middle hepatic vein (MHV) drainage. It can cause graft dysfunction and failure. Inclusion of the MHV in the right lobe graft allows optimal venous drainage but can pose adverse effects for the donor. From May 2005 to April 2011, we performed 202 right-lobe LDLTs using grafts that all (except two) contained the MHV. The mean duration of donor surgery was 558±132 minutes (median 540, range 332-1100), and estimated blood loss 441±309 mL (median 350, range 35-3200). No donor was admitted to the intensive care unit postoperatively. The mean hospital stay was 8.7±2.1 days (median 8, range 6-22). Postoperatively, 39 donors (19.5%) experienced Clavien grade I and II complications, mostly minor wound infections or massive ascites necessitating diuretic therapy. Seven (3.5%) donors displayed Clavien grade III complications, including five bile leakages requiring endoscopic retrograde biliary drainage and two abdominal wound dehiscences requiring repair under general anesthesia. There was no donor death. In conclusion, inclusion of the MHV in a right-lobe LDLT was safe for most donors.

    ABSTRACT: To analyze the outcomes of patients with high Model for End-Stage Liver Disease (MELD) scores who underwent adult-to-adult live donor liver transplantation (A-A LDLT). From September 2002 to October 2010, a total of 152 adult patients underwent A-A LDLT in our institution. Recipients were stratified into a low MELD score group (Group L; MELD score≤30) and a high MELD score group (Group H; MELD score>30) to compare short-term and long-term outcomes. Of the 152 adult patients who underwent A-A LDLT, 9 were excluded from the analysis because they received ABO-incompatible grafts. Group H comprised 23 and Group L 120 patients. The median follow-up was 21.5 months (range, 3 to 102 m). The mean MELD score was 15.6 in Group L and 36.7 in Group H. There were no significant differences in the mean length of stay in the intensive care unit (Group L: 3.01 days vs Group H: 3.09 days, P=.932) or mean length of hospital stay (Group L: 17.89 days vs. Group H: 19.91 days, P=0.409). There were no significant differences in 1-, 3-, or 5-year survivals between patients in Groups L versus H (91.5% vs 94.7%; 86.4% vs 94.7%; and 86.4% vs 94.7%; P=.3476, log rank). The short-term and long-term outcomes of patients with high MELD scores who underwent A-A LDLT were similar to those of patients with low MELD scores. Therefore, we suggest that high MELD scores are not a contraindication to LDLT.

    ABSTRACT: The aim of our study was to retrospectively investigate the outcomes of hepatic artery (HA) reconstruction by cardiovascular surgeons in adult-to-adult living donor liver transplantation (A-A LDLT). From April 2007 to April 2011, 187 recipients underwent A-A LDLT. After excluding seven ABO-incompatible transplant recipients, we reviewed the courses of 180 patients including 125 men and 55 women of mean age 52.5±9.2 years (range=23-71). One hundred seventy-seven patients received right-lobe grafts with inclusion of middle hepatic vein (MHV); two, right-lobe grafts without MHV; and one, left-lobe graft. A continuous, single-stitch, running suture with the parachute technique was used for HA reconstruction. The anastomosis was performed by cardiovascular surgeons employing surgical loupes with 4.5× magnification. The mean time for an arterial reconstruction was 10.7±4.0 minutes (median=10, range=4-30). Hepatic arterial thrombosis (HAT) was encountered in 3 (1.66%) patients. One HAT that developed on postoperative day 1 was successfully rescued by the intra-arterial infusion of urokinase. Another patient required reoperation due to a redundant kinked HA. A third HAT patient underwent successful retransplantation with a cadaveric graft on postoperative day 6. In our series, no delayed HAT was detected and no recipient deaths were related to HAT. HA reconstruction with a running suture under surgical loupes is a feasible technique in A-A LDLT. A speedy reconstruction can be performed by an experienced cardiovascular surgeon with a low incidence of HAT.

    ABSTRACT: Hepatic arterial thrombosis is a critical complication in living donor liver transplantation (LDLT). Two separate branches of the right hepatic artery (RHA) are sometimes observed and addressed by anastomosis of the larger branch first, then checking backflow from the smaller branch. If not good, the smaller branch must be reconstructed. We used the cystic artery as a conduit for the reconstruction. Meticulous dissection was performed to identify all branches of the hepatic artery in the donor operation. The length of cystic artery preserved was as long as possible. The cystic arterial stump was anastomosed to the stump of the posterior branch the of RHA under microscopic guidance on the back table. Patency was checked through the stump of the anterior branch of the RHA. With this technique, only one orifice, the stump of right anterior hepatic artery, was used for hepatic artery reconstruction. We have performed this technique in two patients. Both had good arterial flow after living donor liver transplantation. This innovative technique is easy and safe, and requires only one anastomosis, which, in theory, decreases the adds of developing hepatic arterial thrombosis.

    ABSTRACT: Artificial grafts are not recommended because of the high incidence of thrombogenic effects. However, in some situations, such as emergency or when no vascular bank is available, an artificial graft must be used. We present a case in which a polytetrafluoroethyline graft was used as a conduit to reconstruct the retrohepatic vena cava severed during living donor liver transplantation (LDLT). A 48-year-old woman had end-stage primary biliary cirrhosis for 5 years received a right lobe liver graft from her son. The retrohepatic vena cava was divided and ligated in several sequences. The upper end of the severed retrohepatic vena cava retracted into the liver parenchyma. The lower end of the severed vena cava was distended, with multiple stitches. A 16-mm artificial graft was used as a conduit to replace the inferin vena cava for outflow reconstruction. The patient tolerated the complicated procedure well. No anticoagulant was used throughout the entire course. The patient has been well with excellent liver function after follow-up for more than 5 years. Magnetic resonance imaging and Doppler ultrasonographic studies showed good patency of the cava with no evidence of thrombosis. We suggest use of an artificial graft in living donor liver transplantation, in particular in urgent situations when autologous or allogeneic vessels are not available.

    ABSTRACT: Outflow obstruction may lead to liver congestion and eventual graft failure after living donor liver transplantation. Various methods of venoplasty provide wider outflow tracts. Most series have suggested use of autologous or allogenic grafts for patch venoplasty. We used a polytetrafluorethylene patch in two patients. Both showed good patency of the outflow tract at Doppler ultrasonography at 7 months and 4 months posttransplantation. A polytetrafluoroethylene patch may be a good alternative when no other autologous or allogeneic vascular patch is available or when the situation is critical.
