Abstract
BACKGROUND Aortohepatic conduits (AHCs) are valuable alternatives when conventional hepatic artery anastomoses are not possible. However, AHCs have earlier and higher occlusion rates and reduced graft and patient survival. While endovascular therapy is safe and effective for conventional anastomotic stenoses, data on AHC stenoses are limited. This study reviewed outcomes for endovascular management of AHC stenosis at a single liver transplant center. METHODS A retrospective review of a prospectively maintained database was performed on the endovascular management of AHC stenosis between January 1, 2000, and December 31, 2016. Medical records, laboratory data, and imaging were analyzed for technical and hemodynamic success, primary and assisted primary patency, and patient and graft survival. RESULTS Seven patients underwent angioplasty a median of 142 days after transplant, and 2 required reintervention. The primary patency rate was 67% at 6 months and 22% at 1 year. The assisted primary patency rate was 83% at 6 months and 42% at 1, 3, and 5 years. Patient and graft survival were 86% at 6 months and 71%, 57%, and 38% at 1, 3, and 5 years, respectively. Four conduits were patent at last follow-up. There were no major adverse events after angioplasty. One reintervention was complicated by acute AHC thrombosis after stenting, causing biliary necrosis, sepsis, and death. There was no 30-day mortality, retransplant, or surgical revascularization because of endovascular intervention. CONCLUSIONS Endovascular treatment of AHC stenosis appears to be safe with a high technical success rate but lower long-term patency than standard hepatic arterial anastomoses.

Abstract
Background The aim of this study was to assess the impact of placement of an aortohepatic conduit on graft and patient survival after liver transplantation (LT) in selected patients with an inadequate recipient hepatic artery (HA) for a standard arterial anastomosis. Material/Methods Of 331 patients who underwent deceased donor LT, 25 (7.6%) who received placement of an aortohepatic conduit at the time of transplantation were included. Clinical characteristics and outcomes, including postoperative complications, conduit patency, and graft and patient survival rates, were analyzed. Results All 25 patients included in this study presented a high preoperative Model for End-stage Liver Disease score (25.4±8.6; range, 6–42) and high rates of retransplantation (n=11, 44%) or previous abdominal – pelvic surgery (n=5, 20%). The observed postoperative vascular complications were portal vein thrombosis in 3 cases (12%) and anastomosis-site bleeding of the aortohepatic conduit in 1 case (4%); there was no HA thrombosis or stenosis in our analysis. With a median follow-up of 37 months (range, 0–69 months), all aortohepatic conduits were patent, and the graft and patient survival rates were 84% and 68%, respectively. The causes of death were graft failure (n=4), pneumonia (n=3), and cerebrovascular accidents (n=1). Conclusions Our results indicate that placement of an aortohepatic conduit is a feasible alternative to a standard arterial anastomosis in selected patients whose HA and surrounding potential inflow arteries are not suitable for standard arterial anastomosis.

Abstract
PURPOSE This study sought to assess the effectiveness of rotational thrombectomy (RT) with the Rotarex device in the treatment of thrombotic occlusions in native arteries, by-pass grafts, stents and stent-grafts. MATERIALS AND METHODS Over the last 4 years, 22 patients (14 men and 8 women; mean age 62.6 years) affected by 5 acute (<14 days) thrombotic occlusions of the native arteries (4 plaque thromboses in the common iliac artery and one on a dissection intimal flap of the external iliac artery), 17 subacute and chronic thromboses affecting 4 femoro-popliteal by-pass grafts, 10 stents (7 in the common iliac artery and 3 in the superficial femoral artery) and 3 stents-grafts were studied. Acute thromboses of native arteries were follow-up with colour-Doppler ultrasound (US) examination at 1 and 3 months. Subacute and chronic thrombotic occlusions were follow-up with colour-Doppler US examination at 1, 3, 6 and 12 months and yearly thereafter. RESULTS Immediate technical success was achieved without any need for additional procedures in all acute occlusions of native arteries (4/22 cases). In the subacute and chronic occlusions, the procedure was completed with percutaneous transluminal angioplasty (PTA) (8/22), cutting balloon (6/22) and stenting (5/22). The complication rate was 4.8% (1 rupture of the external iliac artery repaired with a stent-graft). CONCLUSIONS Arterial recanalisation with RT is the treatment of choice for acute thrombosis of healthy native arteries (4-7 mm); the treatment of thrombosis complicating calcified plaques or dissection intimal flaps may cause rupture of the arterial wall. In subacute and chronic occlusions of by-pass grafts, stents and stent grafts, additional procedures are necessary to achieve complete recanalisation.

Abstract
Arterial problems remain a formidable challenge in liver transplantation. In many situations, an aortohepatic conduit can provide a solution. No long-term results (over 5 years) have been reported. This study was designed to assess the impact of aortohepatic conduits on graft survival after liver transplantation and the safety of aortohepatic conduits and to establish the long-term results (up to 20 years) of aortohepatic conduits. Data from 2346 adult liver transplants were prospectively collected into the computerized database and analyzed. In the majority of cases, arterial conduits were constructed from the donor iliac artery obtained at the liver retrieval. Aortohepatic conduits were required in 149 (6.4%) first transplants. The long-term graft survival after liver transplantation using aortohepatic conduits was excellent and comparable to that of the control group. The graft survival was 59% with the conduit versus 67% without the conduit at 5 years of follow-up, 50% versus 52% at 10 years, and 33% versus 35% at 15 years. With up to 20 years of follow-up, there was no statistically significant difference in graft survival, patient survival, hepatic artery complications, or biliary complications. For the same time period, there was no statistically significant difference in graft survival or patient survival for the retransplants with and without aortohepatic conduits. In conclusion, in experienced hands, aortohepatic conduits can be used safely for liver transplantation with no negative impact on long-term graft survival, patient survival, hepatic artery complications, or biliary complications. Excellent long-term results can be obtained.

Abstract
Improvements in surgical technique, advances in the field of immunosuppresion and the early diagnosis and treatment of complications related to liver transplantation have all led to prolonged survival after liver transplantation. In particular, advances in diagnostic and interventional radiology have allowed the Interventional Radiologist, as part of the transplant team, to intervene early in patients presenting with complications related to organ transplant with resultant increase in graft and patient survival. Such interventions are often achieved using minimally invasive percutaneous endovascular techniques. Herein we present an overview of some of these diagnostic and therapeutic approaches in the treatment and management of patients before and after liver transplantation.
