Abstract
Liver transplantation continues to rapidly evolve, and in 2020, 8906 orthotopic liver transplants were performed in the United States. As a technically complex surgery with multiple vascular anastomoses, stenosis and thrombosis of the venous anastomoses are among the recognized vascular complications. While rare, venous complications may be challenging to manage and can threaten the graft and the patient. In the last 20 years, endovascular approaches have been increasingly utilized to treat post-transplant venous complications. Herein, the evaluation and interventional treatment of post-transplant venous outflow complications, portal vein stenosis, portal vein thrombosis, and recurrent portal hypertension with transjugular intrahepatic portosystemic shunt (TIPS) are reviewed.

Morris RI, Jackson N, Smith A, Black SA. A Systematic Review of the Safety and Efficacy of Inferior Vena Cava Stenting. Eur J Vasc Endovasc Surg 2023; 65:298-308. [PMID: 36334902 DOI: 10.1016/j.ejvs.2022.11.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 10/05/2022] [Accepted: 11/01/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVE Inferior vena cava (IVC) stenting may provide benefit to patients with symptomatic obstruction; however, there are no devices currently licensed for use in the IVC and systematic reviews on the topic are lacking. The aim of this study was to carry out a systematic review of the literature and meta-analysis to investigate the safety and efficacy of IVC stenting in all adult patient groups. DATA SOURCES The Medline and Embase databases were searched for studies reporting outcomes for safety and effectiveness of IVC stenting for any indication in series of 10 or more patients. REVIEW METHODS A systematic review of the literature was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS Thirty-three studies were included describing 1 575 patients. Indications for stenting were malignant IVC syndrome (229 patients), thrombotic disease (807 patients), Budd-Chiari syndrome (501 patients), and IVC stenosis post liver transplantation (47 patients). The male:female ratio was 2:1 and the median age ranged from 30 to 61 years. The studies included were not suitable for formal meta-analysis as 30/33 were single centre retrospective studies with no control groups and there was considerable inconsistency in outcome reporting. There was significant risk of bias in 94% of studies. Median reported technical success was 100% (range 78 - 100%), primary patency was 75% (38 - 98%), and secondary patency was 91.5% (77 - 100%). Major complications were pulmonary embolism (three cases), stent migration (12 cases), and major bleeding (15 cases), and there were three deaths in the immediate post-operative period. Most studies reported improvement in clinical symptoms but formal reporting tools were not used consistently. CONCLUSION The evidence base for IVC stenting consists of predominantly single centre, retrospective, observational studies that have a high risk of bias. Nonetheless the procedure appears safe with few major adverse events, and studies that reported clinical outcomes demonstrate improvement in symptoms and quality of life. Randomised controlled trials and prospective registry based studies with larger patient numbers and standardised outcome are required to improve the evidence base for this procedure.

IVC angioplasty using an autologous vascular graft for IVC stenosis due to metallic stent in a pediatric liver transplant. Pediatr Transplant 2019; 23:e13475.

Abstract
A 12-year-old girl underwent LDLT using a left lobe graft for hepatic dysfunction associated with citrin deficiency. A continuous anastomosis suture technique was performed between the recipient's IVC and the donor's left hepatic vein. At age 14, the patient developed intractable ascites. Venography of the IVC and hepatic vein showed twisted-shape stenosis of the hepatic vein-IVC anastomosis with intravascular pressure gradient, probably due to the enlarged transplanted liver, for which a metallic stent was placed. The ascites disappeared, and the patient was making satisfactory progress eight months after surgery. However, nine months after surgery, the ascites appeared again with edema in the lower extremities. Since the stent that had been inserted was suspected of hampering the outflow of the graft liver and IVC, it was decided to conduct stent removal and IVC angioplasty. After intravascular exploration, the stent was removed. Angioplasty was performed. An autologous vascular graft patch was designed to be wedge-shaped to fit the incised part of the IVC, and it was sutured with 5-0 non-absorbable surgical sutures using a continuous suture technique. No postoperative complications or perioperative graft dysfunction were observed. The ascites decreased markedly, and the edema in the lower extremities disappeared. Thus, we were able to successfully perform IVC angioplasty using an autologous vascular graft patch in a patient who developed IVC stenosis after stenting. This procedure is one of the most effective treatment options, especially for pediatric patients requiring long-term vascular patency.

Abstract
Budd-Chiari syndrome (BCS) is a rare but life-threatening disease. If not treated promptly, it is almost always lethal with progressive liver failure, severe nutritional depletion, and renal failure at the late stage. We report the successful treatment of a 5-year-old boy with BCS due to a stenosis of the inferior vena cava (IVC) with a 26-year follow-up. We performed a percutaneous transluminal angioplasty, which resulted in a great improvement of BCS and the disappearance of ascites. Restenosis occurred at 25 years after the initial angioplasty, for which balloon angioplasty was repeatedly performed. The IVC was patent at 1-year follow-up after the second angioplasty.

Abstract
Liver transplantation (LT) is commonly used to treat patients with end-stage liver disease. The evolution of surgical techniques, endovascular methods, and medical care has led to a progressive decrease in posttransplant morbidity and mortality. Despite these improvements, a multidisciplinary approach to each patient remains essential as the early diagnosis and treatment of the complications of transplantation influence graft and patient survival. The critical role of interventional radiology in the collaborative approach to the care of the LT patient will be reviewed. Liver Transplantation 23 1328-1341 2017 AASLD.

Abstract
The purpose of this study was to evaluate the longterm outcomes of stent placement for a hepatic venous outflow obstruction in adult liver transplantation recipients. From June 2002 to March 2014, 23 patients were confirmed to have a hepatic venous outflow obstruction after liver transplantation (18 of 789 living donors [2.3%] and 5 of 449 deceased donors [1.1%]) at our institute. Among these patients, stent placement was needed for 16 stenotic lesions in 15 patients (12 males, 3 females; mean age, 51.7 years). The parameters that were documented retrospectively were technical success, clinical success, complications, recurrence, and the patency of the stent. The technical success rate was 100% (16/16). Clinical success was achieved in 11 of the 15 patients (73.3%). A major complication occurred in only 1 patient-a hepatic vein laceration during the navigation of the occluded segment. The median follow-up period was 33.5 months (range, 0.5-129.3 months), and the overall 1-, 3-, and 5-year primary patency rates of the stent were all 93.8%. One case of occlusion of the stent without clinical signs and symptoms was observed 5 days after the initial procedure. In this patient, the stent was recanalized by balloon angioplasty and showed patent lumen for 48 months of the subsequent follow-up period. In conclusion, stent placement is a safe and effective treatment modality with favorable longterm outcomes to treat hepatic venous outflow obstruction in adult liver transplantation recipients.

Abstract
PURPOSE To evaluate safety and efficacy of balloon dilation and stent placement combined with thrombus aspiration and thrombolysis to treat patients with Budd-Chiari syndrome (BCS) with inferior vena cava (IVC) thrombosis. MATERIALS AND METHODS Charts from 55 consecutive patients with primary BCS and IVC thrombosis treated between April 2000 and August 2014 were retrospectively analyzed. Transcatheter aspiration and percutaneous recanalization were attempted in all patients, and stents were placed if balloon dilation was successful. Catheter-directed thrombolysis was performed when evident clot burden was present after recanalization. RESULTS Technically successful IVC recanalization was achieved in 53 of 55 patients (96.4%). Technical failures in 2 patients were due to long segment of IVC obstruction. A stent was placed in 47 of 53 patients (88.7%). Thrombus was successfully aspirated in 23 patients, and thrombolytic treatment was administered to 13 patients. Median follow-up was 58 months (range, 8-180 mo). No symptomatic pulmonary embolism occurred. Reocclusion occurred in 8 patients, and 6 of these patients (75%) underwent repeat recanalization by balloon dilation with or without stents. Cumulative 1-, 5-, and 10-year primary patency rates were 94%, 89%, and 66%. Alanine transaminase and alkaline phosphatase levels were independent risk factors for reocclusion. Cumulative 1-, 5-, and 10-year survival rates were 90%, 86%, and 86%. Child-Pugh score and reocclusion were independent predictors of survival. CONCLUSIONS Percutaneous vena caval balloon dilation and stent placement with thrombus aspiration and thrombolytic therapy is safe and effective for treatment of patients with BCS and IVC thrombosis.

Abstract
The purpose of our study was to address the long-term outcome of angioplasty and stent placement for hepatic venous outflow obstruction following pediatric liver transplantation. From October 1999 to December 2011, 20 stenotic lesions were confirmed to constitute hepatic venous outflow obstruction in 18 pediatric patients (13 boys, 5 girls) among 152 pediatric patients following liver transplantation and were managed with endovascular intervention. Stent placement was favored over additional angioplasty in patients of preadolescent or adolescent age (>8 years old), after 1 or 2 sessions of balloon angioplasty. The primary patency and assisted primary patency were estimated using the Kaplan-Meier method. A total of 32 procedures (24 balloon angioplasties, 8 stent placements) were conducted. The technical success rate was 90.6% (29/32). Clinical success was achieved in 15 of 18 patients (clinical success rate of 83.3%). Major complications did not occur in our study. Median follow-up was 91.5 months (interquartile range, 54.7-137.3 months) for the 18 patients. The 1-year, 3-year, 5-year, and 10-year primary patencies of the 20 treated lesions were 63.5%, 57.8%, 57.8%, and 57.8%, respectively. The 1-year, 3-year, 5-year, and 10-year assisted-primary patencies of the lesions were 100%, 100%, 100%, and 100%, respectively. Of the 6 patients of preadolescent or adolescent age, 5 patients underwent stent placement procedures, and the stents were patent during the follow-up period of 57.3-162.5 months (median, 72.7 months). In conclusion, endovascular intervention is very effective in hepatic venous outflow obstruction following pediatric liver transplantation. In addition, early stent placement in patients of preadolescent or adolescent age can provide a safe and favorable long-term outcome.

Utility of liver biopsy in predicting clinical outcomes after percutaneous angioplasty for hepatic venous obstruction in liver transplant patients. World J Hepatol 2015; 7:1884-1893. [PMID: 26207170 PMCID: PMC4506946 DOI: 10.4254/wjh.v7.i14.1884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2015] [Revised: 06/16/2015] [Accepted: 07/14/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To determine utility of transplant liver biopsy in evaluating efficacy of percutaneous transluminal angioplasty (PTA) for hepatic venous obstruction (HVOO).
METHODS: Adult liver transplant patients treated with PTA for HVOO (2003-2013) at a single institution were reviewed for pre/post-PTA imaging findings, manometry (gradient with right atrium), presence of HVOO on pre-PTA and post-PTA early and late biopsy (EB and LB, < or > 60 d after PTA), and clinical outcome, defined as good (no clinical issues, non-HVOO-related death) or poor (surgical correction, recurrent HVOO, or HVOO-related death).
RESULTS: Fifteen patients meeting inclusion criteria underwent 21 PTA, 658 ± 1293 d after transplant. In procedures with pre-PTA biopsy (n = 19), no difference was seen between pre-PTA gradient in 13/19 procedures with HVOO on biopsy and 6/19 procedures without HVOO (8 ± 2.4 mmHg vs 6.8 ± 4.3 mmHg; P = 0.35). Post-PTA, 10/21 livers had EB (29 ± 21 d) and 9/21 livers had LB (153 ± 81 d). On clinical follow-up (392 ± 773 d), HVOO on LB resulted in poor outcomes and absence of HVOO on LB resulted good outcomes. Patients with HVOO on EB (3/7 good, 4/7 poor) and no HVOO on EB (2/3 good, 1/3 poor) had mixed outcomes.
CONCLUSION: Negative liver biopsy greater than 60 d after PTA accurately identifies patients with good clinical outcomes.

[PMID: 26017456 DOI: 10.1007/s00270-015-1120-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2015] [Accepted: 04/21/2015] [Indexed: 10/23/2022]
Abstract
Refractory ascites (RA) is thought to complicate the postoperative course of 5-7% (Nishida et al. in Am J Transplant. 6: 140-149, 2006; Gotthardt et al. in Ann Transplant. 18: 378-383, 2013) of liver transplant recipients. RA after liver transplantation is often a frustrating diagnostic dilemma with few good management options unless an obvious mechanical factor is identified. Supportive therapies often fail until a treatable precipitating cause is identified and removed. We describe two patients who developed RA following liver transplantation for primary sclerosing cholangitis, and hepatitis C and alcoholic liver disease, respectively. The cause for RA was hyperkinetic portal hypertension secondary to splenomegaly in the first case and a pancreatic AVM in the 2nd case. After failure of other interventions, surgical splenectomy resulted in immediate and durable resolution of the previously intractable ascites.

Abstract
Obstruction of the inferior vena cava (IVC) is a rare complication of liver transplantation with significant consequences including intractable ascites and hepatic dysfunction. Although venoplasty and stenting are effective in many cases, patients who fail first-line treatment may require surgical intervention or re-transplantation. Scheduled sequential balloon dilation, an approach frequently used to treat fibrotic, benign biliary strictures, but less commonly vascular lesions, may avert the need for such high-risk alternatives while achieving favorable clinical and angiographic response. Herein, we report the case of a 36-year-old woman with transplant-related, initially angioplasty-resistant IVC stenosis that was successfully treated with sequential balloon dilation.
