An 18-year-old male living donor for his father with end-stage liver cirrhosis due to hepatitis B underwent an extended right lobe donor hepatectomy. The middle hepatic vein was visualised on the cut surface of the graft and dissected up to the confluence of the middle and left hepatic veins. After vascular clamping, right and middle hepatic veins were cut to removed the graft. While starting the stump closure, the clamp over the middle hepatic vein slipped and the vein stump sutured quickly under suboptimal exposure. Soon after this closure, the remnant liver showed increasing congestion. Intraoperative Doppler ultrasound revealed obstruction of venous outflow at the remnant left liver due to stenosis in the left hepatic vein. Under total hepatic vascular occlusion, the sutures were removed from the narrowed left hepatic vein. A 2 × 2 cm peritoneal patch from the subcostal area that was prepared to close the defect was sutured to the edges of the left hepatic vein defect. Venous congestion of the liver disappeared when the clamps were removed. Intraoperative Doppler ultrasound confirmed normal hepatic venous flow. The postoperative course of the donor was uneventful. There was no clinical, biochemical, or radiological problems at 47 months of follow-up. An autogenous peritoneal patch may be a good option to repair vascular defects, which are not suitable for primary sutures, due to easy accessibility and size adjustment, cost effectiveness, as well as relatively low risk of infection and thrombosis. Close dissection of the left hepatic vein during parenchymal transection over the middle hepatic vein can result in narrowing, particularly at the bifurcation of the middle/left hepatic veins that can cause congestion in the remnant liver. When we include the middle hepatic vein with the right graft, we now believe that dissection away from the left hepatic vein seems much more secure for donors.

    ABSTRACT: The lack of use of a common grading system in reporting morbidity impedes estimation of the true risk to a right lobe living donor (RLLD). We report outcomes in 91 consecutive RLLD's using the validated 5-tier Clavien grading and a quality of life (QOL) questionnaire. The median follow-up was 79 months. The donors were predominantly female (66%), 22 (24%) received autologous blood transfusions. Fifty-three complications occurred in 43 donors (47% morbidity), 19 (37%) were ≥ Grade III, biliary fistula (14%) was the most common. There was no donor mortality. Two intraoperative complications could not be graded and two disfiguring complications in female donors were graded as minor. Two subgroups (first 46 vs. later 45 donors) were compared to study the presence if any, of a learning curve. The later 45 donors had lesser autologous transfusions, lesser rehospitalization and no reoperation and a reduction in the proportion of ≥ Grade III (major) complications (24% vs. 50%; p = 0.06). In the long term, donors expressed an overall sense of well being, but some sequelae of surgery do restrain their current lifestyle. Our results warn against lackadaisical vigilance once RLLD hepatectomy becomes routine.

    ABSTRACT: The harvesting of the middle hepatic vein (MHV) with the right lobe graft for living-donor liver transplantation allows an optimal venous drainage for the recipient; however, it is an extensive operation for the donor. This is a prospective, nonrandomized study evaluating liver functions and early clinical outcome in donors undergoing right hepatectomy with or without MHV harvesting. From August 2005 to July 2007, a total of 100 donor right hepatectomies were performed with (n = 49) or without (n = 51) the inclusion of the MHV. The decision to take MHV was based on an algorithm that considers various donor and recipient factors. There was no donor mortality in donors in either group. Overall complication rate was higher in MHV (+) donor group, however when remnant liver volume was kept above 30%, complication rates were similar between the groups. The results of this study show that right hepatectomy including the MHV neither affects morbidity nor impairs early liver function in donors when remnant volume is kept above 30%. The decision, therefore, of the extent of right lobe donor hepatectomy should be tailored to the particular conditions considering the graft quality and metabolic demand of the recipient.

    ABSTRACT: Abdominal vascular injuries are among the most challenging and lethal injuries in traumatized patients. Inferior vena cava is the most frequently injured vein during the blunt or penetrating trauma. The primary repair, end to end anastomosis, endovascular stenting, or graft interposition with autogenous or synthetic materials should be considered in selected cases. However, in cases the synthetic graft was preferred, intestinal contaminations due to small or large bowel perforation accompanying the trauma have been cited as a limiting factor for the use of such grafts as in the current case. However, a previous history of lower leg variceal surgery prevents the use of great saphenous vein as a graft. So in the present case, the authors report a patient with inferior vena cava injury repaired with autogenous peritoneo-fascial graft. The authors have used APF graft in traumatic inferior vena cava injury for the first time.
