Surgery 2023; 174:1263-1269. [PMID: 37709647 DOI: 10.1016/j.surg.2023.08.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 07/05/2023] [Accepted: 08/08/2023] [Indexed: 09/16/2023]
Abstract
BACKGROUND The outcomes of liver transplantation with hepatic arterial reconstruction using interposition saphenous vein conduits are not widely reported. Here, we share our experience using great saphenous vein conduits for hepatic arterial reconstruction in living donor liver transplantation. METHODS This was a single-center retrospective review of patients who underwent living donor liver transplantation (n = 950). The saphenous vein conduits were used in 39 patients. We compared hepatic artery thrombosis, graft dysfunction, and 30-day and 1-year survival in the early (2012-2017) and late (2017-2020) transplant periods. RESULTS Among 39 patients (of whom 30 [76.9%] were males, median Model for End-Stage Liver Disease was 24 [interquartile range, 17-27], median age was 50 [interquartile range, 43-54]), saphenous vein conduits were placed on supra celiac aorta in 7 (17.9%), infrarenal aorta in 25 (64.1%), and other arteries in 7 (17.9%) patients. The number of biliary and hepatic vein anastomoses, total arterial ischemia time, portal vein-hepatic artery reperfusion time, and duration of surgery was different in the 2 groups (P < .05). The 30-day mortality was 5/21 (23.8%) and 0 in the early and late periods (P = .05). The 30-day survival was >90% in patients with portal vein-hepatic artery reperfusion time <240 minutes, ≤2 grade 3 complications, no graft dysfunction, and later period of transplantation (P < .05). The 1-year survival with standard transplantation, transplantation with saphenous vein conduits in the early and late period was 87%, 62%, and 89% (P = .022). CONCLUSION Liver transplantation with saphenous vein conduits is associated with acceptable outcomes. Major complications and arterial ischemia times are major determinants of outcomes.

Abstract
Hepatic artery thrombosis (HAT) after liver transplantation is associated with a marked increase in morbidity, leading to graft and patient loss. We evaluated the outcomes of adult living donor liver transplantation patients with HAT under an aggressive surgical intervention. A total of 1355 recipients underwent adult living donor liver transplantation at the Seoul National University Hospital. Surgical redo reconstruction for HAT was performed in all cases except in those with graft hepatic artery injury and late detection of HAT. Postoperative HAT developed in 33 cases (2.4%) at a median time of 3.5 days. Thirty patients (90.9%) underwent redo-arterial reconstruction. The survival rates in patients with HAT were similar to the rates in those without HAT (72.7% vs. 83.8%, p = 0.115). Although graft survival rates were lower in patients with HAT (84.8%) than in those without HAT (98.0%) ( p < 0.001), the graft survival rate was comparable (92.0% vs. 98.0%, p = 0.124) in the 25 patients with successful revascularization. Biliary complication rates were higher in patients with HAT (54.5%) than in those without HAT (32.0%) ( p = 0.008). In conclusion, the successful redo reconstruction under careful selection criteria saved the graft without retransplantation in 96.0% of the cases. Surgical revascularization should be preferentially considered for the management of HAT in adult living donor liver transplantation.

Abstract
Ensuring optimal arterial flow in solid organ transplantation is very important. Insufficient flow causes important problems such as bile duct problems, intrahepatic abscess formation, and organ loss. Arterial intimal dissection is an important factor that negatively affects organ blood flow. In this study, hepatic artery dissections that we detected in patients who underwent living donor liver transplantation in our clinic were defined, and the microvascular intima-adventitial fixation technique, which can be considered a new approach, was described.

Abstract
Poorer than expected, living donor liver transplant outcomes are observed after recipient graft artery thrombosis. At grafting, the risk for later thrombosis is high if a dissected hepatic artery is used for standard reconstruction. Surgeon diagnosis of dissection requires nonstandard management with alternative technique in addition to microvascular expertise. Intimal flap repair with standard reconstruction is contingent on basis of a redo anastomosis. It is a suboptimal choice for living donor transplantation. Achieving goal graft arterial perfusion at first revascularization is crucial for superior outcomes. Managing dissection at grafting with nonstandard left gastric artery reconstruction is unreported. Our experience is limited, but this is our preferred alternative technique to standard hepatic artery reconstruction complicated by dissection. Here, we describe our two-case experience with left gastric arterialized grafts for management of dissection. Our living donor graft recipients with alternatively arterialized grafts are now 6- and 2-years posttransplant.

Abstract
In living donor liver transplantation, hepatic artery intimal dissection is a rare but devastating complication often resulting in the inability to utilize the graft. We detail the salvage of a dissected donor right hepatic artery utilizing the recipient hepatic artery. After removal of the right lobe, the donor artery was found to have an intimal dissection extending to multiple branches. The liver transplant surgeons requested their plastic microsurgeon colleague to assist with reconstruction. Ultimately, the native recipient hepatic artery was used as a branch graft as the caliber and branching pattern was appropriate. Back table microvascular reconstruction was performed using the explanted recipient hepatic artery branches as a graft to the four donor artery branches. Every anastomosis was assessed with intraoperative doppler; all were patent with acceptable flow characteristics. The patient did well post-operatively with post-operative ultrasounds demonstrating patency of the graft. Four months post-transplantation the patient developed two polymicrobial abscesses that were drained and resolved with normalization of liver function tests. This case highlights how collaboration with a microvascular surgeon enabled the salvage of a living donor graft when faced with a complex arterial dissection.

Abstract
BACKGROUND Living donor liver transplant (LDLT) for hepatocellular carcinoma (HCC) has been controversial in terms of selection and outcome. We share our experience of LDLT for HCC in Indian patients. METHODS Retrospective analysis of patients undergoing LDLT for HCC discovered either preoperatively or incidentally on explant pathology was done. Preoperative characteristics and explant histopathology findings were recorded. Overall, recurrence-free survival and factors predicting recurrence were analyzed. RESULTS Six hundred and eleven LDLT were performed between June 2011 and October 2019. HCC constituted 6.5% (n = 53) of transplant activity. Forty had preoperative diagnosis, while 13 were detected incidentally. The median model for end-stage liver disease (MELD) score was 18 for patients with HCC. Only in 10 patients (19%), HCC was the primary indication for liver transplant (LT), and the rest had undergone transplant for progressive decompensation. Thirty-two patients were within up-to-7, while 21 were outside up-to-7 criteria. Overall 5-year survival was 85.4% and recurrence-free survival was 83.3% after a median follow-up of 35 months (13-59). This was similar to LDLT for other indications (81.2% at 5 years). Risk Estimation of Tumor Recurrence After Transplant (RETREAT) score was best able to predict recurrence (p = 0.03) with odds ratio of 6.8. CONCLUSION Patients with HCC in India present late for liver transplant. Most patients have some form of decompensation before they undergo LT. In selected patients, overall survival was comparable with other indications for LDLT with acceptable recurrence rates. RETREAT score was best to predict recurrence.
