Long-term outcomes of individualized treatment strategy in treatment of type I Budd-Chiari syndrome in 456 patients

Vascular liver diseases: A sex-oriented analysis of the literature

Vascular liver diseases are an heterogenous group of diseases that collectively represent an important health issue in the field of liver diseases. This narrative review was elaborated by the Special Interest Group (SIG) "Gender in Hepatology" of the Italian Association for the Study of the Liver (AISF). We aimed to review the current knowledge regarding the potential role of biological sex in patients with vascular liver diseases such as splanchnic vein thrombosis, hepatic vein thrombosis, porto-sinusoidal vascular disorder, and hereditary hemorrhagic telangiectasia. As vascular liver diseases commonly affect young individuals, including women in childbearing age, we also included a specific section on the management of pregnancy in these challenging patients.

Evaluation of outcome from endovascular therapy for Budd-Chiari syndrome: a systematic review and meta-analysis

This study was performed to evaluate the outcome of endovascular intervention therapy for Budd-Chiari syndrome (BCS) and compare recanalization, transjugular intrahepatic portosystemic shunt (TIPS)/direct intrahepatic portosystemic shunt (DIPS), and combined procedure treatment. For the meta-analysis, 71 studies were identified by searching four databases. The individual studies’ samples were used to calculate a confidence interval (CI 95%), and data were pooled using a fixed-effect model and random effect model. The pooled measure and an equal-weighted average rate were calculated in all participant studies. Heterogeneity between the studies was assessed with I², and T² tests, and publication bias was estimated using Egger’s regression test. A total of 4,407 BCS patients had undergone an endovascular intervention procedure. The pooled results were 98.9% (95% CI 97.8‒98.9%) for a technical success operation, and 96.9% (95% CI 94.9‒98.9%) for a clinical success operation. The re-intervention rate after the initial intervention procedure was 18.9% (95% CI 14.7‒22.9%), and the survival rates at 1 and 5 years after the initial intervention procedure were 98.9% (95% CI 96.8‒98.9%) and 94.9% (95% CI 92.9‒96.9%), respectively. Patients receiving recanalization treatment (98%) had a better prognosis than those with a combined procedure (95.6%) and TIPS/DIPS treatment (94.5%). The systematic review and meta-analysis further solidify the role of endovascular intervention treatment in BCS as safe and effective. It maintains high technical and clinical success and long-term survival rates. The recanalization treatment had a better prognosis and outcome than the combined procedures and TIPS/DIPS treatment.

Long-term outcomes of individualized interventional treatment for primary Budd-Chiari syndrome complicated by inferior vena cava thrombosis

BACKGROUND

Various endovascular treatments were used for Budd-Chiari syndrome (BCS) patients complicated by inferior vena cava (IVC) thrombosis. The best treatment for this disease remains unknown. To evaluate safety and efficacy of individualized interventional treatment for primary BCS with IVC thrombosis.

METHODS

Forty-seven consecutive patients with IVC involvement BCS complicated by IVC thrombosis between June 2002 and August 2020 were analyzed retrospectively. They were treated with individualized interventional treatment based on thrombus type and size. Agitation thrombolysis, transcatheter thrombus aspiration, and catheter-directed thrombolysis were initially used for fresh and mixed thrombus (n = 20), then stent implantation for compressing thrombus and IVC recanalization were performed according to the size of the residual thrombus. Direct balloon angioplasty was used for old thrombus (n = 27).

RESULTS

Median follow-up duration was 109 (5-223) months (average 114 ± 60 months). IVC recanalization were attempted in forty patients and failed in one. The technical successful rate of IVC recanalization was 97.5%. Thrombus was completely lysed in eight patients with fresh thrombus (40%, 8/20), partially lysed in 11 patients with mixed thrombus (55%, 11/20), and no response in one patient with mixed thrombus (5%, 1/20). Thrombolytic-related complications occurred in one patient (5%, 1/20). No symptomatic pulmonary embolism occurred. Among the 11 patients with thrombus partially lysed, five patients underwent stent implantation for compressing thrombus, six patients received conservative treatment. Old thrombus was completely lysed in 15 patients (55.6%, 15/27) during follow-up. Restenosis occurred in six patients (15.4%, 6/39). Primary patency rates at 1, 5, 10 and 15 years were 92, 92, 86 and 80%, respectively. Hepatocellular carcinoma (HCC) occurred in four patients (8.5%, 4/47). One patient died of HCC. The survival rate was 97.9%.

CONCLUSIONS

The individualized interventional treatment based on thrombus type and size for primary BCS complicated by IVC thrombosis patients is safe and effective with long-term patency and survival.

Budd-Chiari syndrome: consensus guidance of the Asian Pacific Association for the study of the liver (APASL)

Budd Chiari syndrome (BCS) is a diverse disease with regard to the site of obstruction, the predisposing thrombophilic disorders and clinical presentation across the Asia-Pacific region. The hepatic vein ostial stenosis and short segment thrombosis are common in some parts of Asia-Pacific region, while membranous obstruction of the vena cava is common in some and complete thrombosis of hepatic veins in others. Prevalence of myeloproliferative neoplasms and other thrombophilic disorders in BCS varies from region to region and with different sites of obstruction. This heterogeneity also raises several issues and dilemmas in evaluation and approach to management of a patient with BCS. The opportunity to recanalize hepatic vein in patients with hepatic vein ostial stenosis or inferior vena cava stenting or pasty among those membranous obstruction of the vena cava is a unique opportunity in the Asia-Pacific region to restore hepatic outflow closely mimicking physiology. In order to address these issues arising out of the diversity as well as the unique features in the region, the Asia Pacific Association for Study of Liver has formulated these guidelines for clinicians.

The outcomes of interventional treatment for Budd-Chiari Syndrome complicated by inferior vena cava thrombosis: Systematic review and meta-analysis

PURPOSE

The aim of this study was to perform a systematic review and meta-analysis to assess the safety and efficacy of interventional treatment for Budd-Chiari syndrome (BCS) complicated by Inferior Vena Cava thrombosis (IVCT) patients.

METHODS

We evaluated the published studies on interventional treatment for BCS complicated by IVCT. Meta-analysis was used to calculate the combined effect size and their 95% confidence intervals (CI) based on random effect. The publication bias was assessed by Begg's test.

RESULTS

Sixteen studies on interventional treatment for BCS complicated by IVCT patient were selected for meta-analysis, a total of 767 BCS complicated by IVCT patients were included. The combined effect size (95% CI) were 99% (98-100%) for the total successful rate of IVC recanalization, 15% (11-21%) for the rate of IVC restenosis after initial operation, 92.0% (86-97%) for the rate of clinical improvement, 76% (68-84%) for the rate of thrombus clearance and 0.00% (0-1%) for the incidence of pulmonary embolism (PE). Through subgroup meta-analysis about the rate of thrombus clearance, we got the pooled results (95% CI) of individualized treatment strategy (ITS) group and non-individualized treatment strategy (non-ITS) group, were 81% (71-92%) and 73% (63-83%), respectively.

CONCLUSIONS

The interventional treatment for BCS complicated by IVCT patients is safe and effective with low incidence of PE, high thrombus clearance rate, high technically successful rate, good patency, and high clinical improvement rate. Moreover, subgroup analysis indicated that management based on the type and extent of the thrombus is proposed.

Inferior vena cava-syndrome

Inferior vena cava syndrome (IVCS) is caused by agenesis, compression, invasion, or thrombosis of the IVC, or may be associated with Budd-Chiari syndrome. Its incidence and prevalence are unknown. Benign IVCS is separated from malignant IVCS. Both cover a wide clinical spectrum reaching from asymptomatic to highly symptomatic cases correlated to the underlying cause, the acuity, the extent of the venous obstruction, and the recruitment and development of venous collateral circuits. Imaging is necessary to determine the underlying cause of IVCS and to guide clinical decisions. Interventional therapy has changed the therapeutic approach in symptomatic patients. This article provides an overview over IVCS and focuses on interventional therapeutic methods and results.

Long-Term Outcomes of Endovascular Interventions in More than 500 patients with Budd-Chiari Syndrome

PURPOSE

To assess and compare the long-term outcomes of various endovascular interventions in patients with Budd-Chiari syndrome (BCS).

MATERIALS AND METHODS

In this single-center retrospective study, 510 consecutive patients with BCS who had undergone a total of 618 endovascular procedures from January 2001 to December 2019 were included. Details of the type of endovascular intervention, technical success, clinical success, patency rate, complications, and survival outcomes were analyzed.

RESULTS

The overall technical success rate was 96% (593 of 618 procedures; 500 in treatment-naïve patients and 93 repeat interventions for recurrent disease). Endovascular procedures included recanalization procedures (angioplasty and stent placement) in 355 patients (71%) and transjugular intrahepatic portosystemic shunt (TIPS) creation in 145 (29%). Major postprocedure complications occurred in 14 patients (2.8%). Vascular/stent restenosis occurred in 95 patients (19%), and successful repeat intervention was performed in 82 of those 95 (86.3%). An additional 11 of these 82 (13.4%) underwent a third intervention for restenosis. In the recanalization and TIPS groups, the 1- and 5-y cumulative patency rates were 87% and 74% and 95% and 68%, respectively. The 1- and 5-y survival rates were 96% and 89% and 90% and 76%, respectively.

CONCLUSIONS

Endovascular interventions for BCS are feasible and safe in the majority of patients, with excellent short- and long-term patency and survival rates.

Budd-Chiari Syndrome: An Uncommon Cause of Chronic Liver Disease that Cannot Be Missed

Budd-Chiari syndrome (BCS), or hepatic venous outflow obstruction, is a rare cause of liver disease that should not be missed. Variable clinical presentation among patients with BCS necessitates a high index of suspicion to avoid missing this life-threatening diagnosis. BCS is characterized as primary or secondary, depending on etiology of venous obstruction. Most patients with primary BCS have several contributing risk factors leading to a prothrombotic state. A multidisciplinary stepwise approach is integral in treating BCS. Lifelong anticoagulation is recommended. Long-term monitoring of patients for development of cirrhosis, complications of portal hypertension, hepatocellular carcinoma, and progression of underlying diseases is important.

Restenosis after recanalization for Budd-Chiari syndrome: Management and long-term results of 60 patients

BACKGROUND

Budd-Chiari syndrome is defined as hepatic venous outflow tract obstruction. For Asian Budd-Chiari syndrome patients, the major treatment modality is recanalization (percutaneous transluminal angioplasty with or without stent implantation). The cumulative 1-, 5-, and 10-year primary patency rates and survival rates are reported to be excellent or satisfactory, but the long-term outcome of patients with restenosis (the most common complication after recanalization) is unknown.

AIM

To explore the treatment strategy for restenosis in patients with Budd-Chiari syndrome after interventional therapy and to evaluate the long-term follow-up results.

METHODS

The clinical data and follow-up results of 60 patients with restenosis after interventional therapy from November 1983 to December 2013 were retrospectively analyzed.

RESULTS

Sixty patients with restenosis were retrospectively divided into a percutaneous transluminal angioplasty (PTA) group (40 patients) and a PTA + stent group (20 patients) according to the primary recanalization method. For the patients with restenosis in the PTA group, 13 refused treatment, and 27 received further treatment; among these patients, five had a second restenosis, two had a third restenosis, and one had a fourth restenosis. For the patients with restenosis in the PTA + stent group, nine refused treatment, ten received PTA alone, and the other received PTA + stent implantation. Among the patients who received further treatment, five had a second restenosis, three had a third restenosis, and one had a fourth restenosis. The 1-, 5-, 10-, 20-, and 25-year cumulative survival rates of the 38 patients who received further treatment after restenosis were 100%, 78.3%, 78.3%, 70.5%, and 70.5%, respectively; however, for the 22 patients who refused treatment, the survival rates were 72.7%, 45.9%, 30.6%, 10.2%, and unavailable, respectively (P < 0.001).

CONCLUSION

Long-term follow-up after interventional therapy is very important. Active treatment for patients with restenosis can improve prognosis, and minimally invasive treatment strategies for restenosis allows to obtain satisfactory results.

Obstructed membranous transformation of the inferior vena cava in patients with hepatic vein-type Budd-Chiari syndrome: A case series

Budd-Chiari syndrome (BCS) is a rare disease characterized by the obstruction of hepatic venous outflow due to occlusion of the hepatic vein (HV) or the inferior vena cava (IVC). The pathophysiology of IVC and HV membranous transformation, which can form in isolation or simultaneously, remains unclear in patients with combined-type BCS. Here we report three cases of patients with BCS demonstrating conversion from HV-type to combined-type. Three patients with only HV-type BCS underwent percutaneous balloon angioplasty (PTA) of the obstructed HV. During follow up, membranous transformation of the IVC was observed. This condition was subsequently treated with PTA of the IVC. These cases demonstrate that HV-type BCS may convert to combined-type BCS.

Accessory hepatic vein recanalization for hepatic vein-type Budd-Chiari syndrome

PURPOSE

To explore the clinical efficacy and long-term outcomes of accessory hepatic vein (AHV) recanalization as a means of treating hepatic vein (HV)-type Budd-Chiari syndrome (BCS).

METHODS

Between January 2011 and December 2018, a total of 46 symptomatic HV-type BCS patients were treated by AHV recanalization in our hospital. The technical and clinical success of this treatment, as well as associated long-term patient prognosis was assessed herein.

RESULTS

The AHV recanalization approach was technically successful in 100% of patients, without any instances of complications associated with the operation. This procedure was 95.7% (44/46) clinically successful and resultant. AHV re-obstruction occurred in 12 patients. The cumulative primary one-, two-, and five-year patency rates were 77.3%, 71.7%, and 71.7%, respectively. The secondary cumulative one-, two-, and five-year patency rates were 97.7, 87.1, and 87.1%, respectively. The five-year patency rates did not differ significantly between patients treated with balloons and stents (p  =  .674). Based on Cox-regression analysis, younger age was an independent predictor of re-obstruction (p = .005). The cumulative one-, two-, and five-year survival rates were 97.7, 92.2, and 92.2%, respectively.

CONCLUSIONS

AHV recanalization is a safe and effective treatment for HV-type BCS.
