Endoscopic ultrasound-guided portosystemic pressure gradient measurement transjugular balloon occlusion measurement in patients with cirrhosis (ENCOUNTER): A bicentric EU study.

Background & Aims: Patients with cirrhosis and portal hypertension are at increased risk of hepatic decompensation and liver-related mortality. While the hepatic venous pressure gradient (HVPG) is the accepted method for quantifying portal hypertension, its measurement and limited availability pose challenges. Endoscopic ultrasound-guided portal pressure gradient (EUS-PPG) provides a direct alternative.

CIRSE Standards of Practice for the Interventional Radiology Management of Acute and Chronic Arterial Mesenteric Ischaemia.

Purpose: Mesenteric ischaemia due to arterial occlusion, usually secondary to atherosclerosis or arterial thromboembolism, may be acute or chronic. Endovascular intervention is now the primary treatment based on its minimally invasive nature and lower in-hospital mortality. Open surgery is indicated in the presence of bowel necrosis, the diagnosis of which remains challenging.

BioPearl™ doxorubicin microspheres for unresectable HCC: a prospective, single-arm, multicenter study: BIOPEARL-ONE.

Drug-eluting microsphere transarterial chemoembolization (DEM-TACE) reduces systemic exposure to chemotherapeutic drugs compared with conventional TACE but permanently occludes the embolized vessels, potentially obviating the possibility of re-treatment with TACE. Temporary embolization by resorbable BioPearl™ microspheres might facilitate subsequent re-treatments. We herein describe the trial protocol of BIOPEARL-ONE, a prospective, single-arm, multicenter, post-market clinical follow-up study.

Patients And Methods: Retrospective study on a cohort of 103 patients who presented with a type II endoleak after EVAR for infrarenal abdominal aortic aneurysm. Maximum diameter and volumetric measurements were calculated on computed tomography follow-up scans at 3 months and 1 year after index surgery.

TIPS, a Trick for Transcaval TEVAR Access.

Purpose: We described an alternative access for thoracic endovascular aortic repair (TEVAR) deployment using a transjugular intrahepatic portosystemic shunt (TIPS) needle for gaining transcaval access to the abdominal aorta.

Case Report: A 63-year-old man presented with a penetrating atherosclerotic ulcer in the descending aorta. Traditional transfemoral and transaxillary access were not possible.

Resin-Based Yttrium-90 Radioembolization as a Bridging or Downstaging Treatment to Liver Transplantation for Hepatocellular Carcinoma.

Purpose: To evaluate the outcomes of resin-based yttrium-90 (Y) transarterial radioembolization (TARE) for hepatocellular carcinoma (HCC) as a bridging or downstaging therapy to liver transplantation (LT) in terms of safety, tumor response, recurrence, and survival.

Materials And Methods: A single-center retrospective analysis of patients with HCC treated with resin-based TARE as bridging or downstaging treatment to LT between January 2006 and April 2021 was performed. TARE-related liver toxicity was assessed.

Sarcopenia in patients receiving TIPS is independently associated with increased risk of complications and mortality.

Background: Sarcopenia is an acknowledged risk factor for individuals with chronic liver disease, however, the influence on outcomes in patients receiving transjugular intrahepatic portosystemic shunt (TIPS) remains underexplored.

Aims: This study aimed to investigate the association between sarcopenia and incidence of complications and mortality post-TIPS.

Methods: A retrospective analysis was performed on 175 patients who underwent TIPS between 2011-2021 at a Belgian tertiary care center.

Endovascular Management of Thrombosed Cavoportal Anastomosis After Liver Transplantation Using Catheter Directed Thrombolysis and Stent Placement: A Case Report.

Cavoportal hemitransposition (CPHT) is a rarely performed treatment technique in liver transplantation in cases of extensive splanchnic thrombosis, in which the inferior vena cava of the recipient is used to perfuse the portal vein of the allograft. A case of a 65-year-old liver transplantation patient with an acutely thrombosed cavoportal anastomosis is presented. After unsuccessful medical treatment, recanalization was obtained with transfemoral catheter directed thrombolysis, angioplasty and stent placement.

The Toulouse algorithm identifies patients with increased risk of cardiac decompensation only in patients with TIPS for refractory ascites.

Introduction And Objectives: TIPS placement is an effective, possibly life-saving, treatment for complications of portal hypertension. The pressure shift induced by the stent can lead to cardiac decompensation (CD). We investigated the incidence of CD, possible variables associated with CD and the validity of the Toulouse algorithm for risk prediction of CD post-TIPS.

Transcatheter arterial embolization for small-bowel bleeding: technical and clinical outcomes and risk factors for early recurrent bleeding.

Background: This study evaluated the technical and clinical outcomes of transcatheter arterial embolization (TAE) in patients with acute small-bowel bleeding (SBB) and aimed to identify potential risk factors for early recurrent bleeding after TAE.

Purpose: Postpartum haemorrhage (PPH) remains a leading cause of maternal death despite current medical management. Surgical interventions are still needed for refractory bleeding. Interventional radiology (IR) can be a successful intermediary that avoids the need for hysterectomy.

Simplification strategies for a patient-specific CFD model of particle transport during liver radioembolization.

Background: Patient-specific 3D computational fluid dynamics (CFD) simulations have been used previously to identify the impact of injection parameters (e.g. injection location, velocity, etc.

Adaptive design of experiments to fit surrogate Gaussian process regression models allows fast sensitivity analysis of the input waveform for patient-specific 3D CFD models of liver radioembolization.

Background And Objective: Patient-specific 3D computational fluid dynamics (CFD) models are increasingly being used to understand and predict transarterial radioembolization procedures used for hepatocellular carcinoma treatment. While sensitivity analyses of these CFD models can help to determine the most impactful input parameters, such analyses are computationally costly. Therefore, we aim to use surrogate modelling to allow relatively cheap sensitivity analysis.

Antithrombotic Therapy and Freedom From Bridging Stent Occlusion After Elective Branched Endovascular Repair: A Multicenter International Cohort Study.

Based on our study, no antithrombotic therapy is significantly associated with bridging stent occlusion, and no evidence of the superiority of other antithrombotic therapy exists. Nevertehless, due to the low number of bridging stent occlusions, this study can neither support nor reject the PRINCE2SS recommendations. Further studies with larger cohorts are needed to determine clear guideliness of the best antithrombotic treatment regimen after complex enfovascular aortic repair.
