Liver regeneration after portal and hepatic vein embolization improves overall survival compared with portal vein embolization alone: mid-term survival analysis of the multicentre DRAGON 0 cohort.

Background: The purpose of this study was to compare 3-year overall survival after simultaneous portal (PVE) and hepatic vein (HVE) embolization versus PVE alone in patients undergoing liver resection for primary and secondary cancers of the liver.

Methods: In this multicentre retrospective study, all DRAGON 0 centres provided 3-year follow-up data for all patients who had PVE/HVE or PVE, and were included in DRAGON 0 between 2016 and 2019. Kaplan-Meier analysis was undertaken to assess 3-year overall and recurrence/progression-free survival.

The RAVI registry: prospective, multicenter study of radial access in embolization procedures - 30 days follow up.

Background: There is a lack of registry studies about transradial access (TRA) outcomes. This prospective registry evaluated the TRA and procedure outcomes of visceral embolizations performed via TRA with 30-day follow-up.

Material & Methods: Prospective, multicenter registry included uterine fibroids (UFE), prostate artery (PAE), liver tumors (LT), and other hypervascular tumors (OHT) embolization performed in six US hospitals.

Minimally invasive management of pathologic fractures of the pelvis and sacrum: Tumor ablation and fracture stabilization.

Background: Pathologic fractures of the pelvis/sacrum due to metastatic bone disease (MBD) cause pain and dysfunction due to mechanical instability of the pelvic ring. This study presents our multi-institutional experience with percutaneous stabilization of pathologic fractures and osteolytic lesions from MBD throughout the pelvic ring.

Methods: The records of patients undergoing this procedure from 2018 to 2022 were reviewed retrospectively from two institutions.

Conception rates after fluoroscopy-guided fallopian tubal cannulation: an alternative to fertilization for patients with tubal occlusion.

Objective: Previous studies show good technical success rates for fallopian tube recanalization. Scarce literature exists regarding advance techniques currently used by interventional radiologists during fallopian tube recanalization procedures. This study investigates the level of intervention and tubal patency and its association with technical success and associated pregnancy outcomes.

Inadvertent noncaval filter deployment and its management.

Inferior vena cava filters are placed to prevent life-threatening pulmonary embolism in a selected group of patients. Significant complications are known to occur with prolonged dwell times, and rarely during initial placement. In this report, we describe two cases of inadvertent noncaval inferior vena cava filter placements, specifically in the azygous vein and right renal vein, and the complex methods used to retrieve them, which exemplify the critical importance of routine and careful placement techniques.

The Changing Face of Hepatocellular Carcinoma: Forecasting Prevalence of Nonalcoholic Steatohepatitis and Hepatitis C Cirrhosis.

Background/objectives: The purpose of this research is to analyze the past and forecast the future prevalence of Hepatitis C Virus (HCV) and Nonalcoholic Steatohepatitis (NASH) and their respective contribution to Hepatocellular Carcinoma (HCC) incidence in the setting of novel anti-viral agents and rising obesity rates in the United States.

Methods: Existing data of HCV and NASH prevalence in the United States utilizing the National Health and Nutrition Examination Survey (NHANES) and Organ Procurement and Transplantation Network (OPTN) was collected and analyzed to project future prevalence trends.

Results: Prevalence of NASH and HCV are expected to increase and decline respectively over the next two decades with alcoholic cirrhosis expected to stay relatively unchanged.

Combination Ipsilateral Lobar and Segmental Radioembolization Using Glass Yttrium-90 Microspheres for Treatment of Multifocal Hepatic Malignancies.

Eight patients with primary (n = 6) and metastatic (n = 2) disease of the liver underwent yttrium-90 radioembolization with glass microspheres using a combination of segmental and ipsilateral lobar approach to treat multifocal tumors containing a single dominant tumor. The superselective dose was administered to the dominant tumor, whereas lobar infusion was used for smaller tumors. Assuming uniform distribution, median dose to the segment with dominant tumor was 412.

Superselective retrograde lymphatic duct embolization for management of postoperative lymphatic leak.

Lymphatic leak is a well-documented complication following neck dissection surgeries. When conservative methods fail to control the leak, thoracic duct embolization becomes an option. Transabdominal access is the standard for this procedure; however, it is not always feasible.

Assessing Intra-arterial Complications of Planning and Treatment Angiograms for Y-90 Radioembolization.

Purpose: To report hepatic arterial-related complications encountered during planning and treatment angiograms for radioembolization and understand any potential-associated risk factors.

Materials And Methods: 518 mapping or treatment angiograms for 180 patients with primary or metastatic disease to the liver treated by Yttrium-90 radioembolization between 2/2010 and 12/2015 were retrospectively reviewed. Intra-procedural complications were recorded per SIR guidelines.

Isolated stenosis of the inferior mesenteric artery: to treat or not to treat?

The indication for treatment of inferior mesenteric artery (IMA) is generally not clear. The IMA is frequently ignored owing to its size and the presence of alternate pathways within the mesenteric vasculature. However, IMA treatment may be indicated in certain clinical scenarios.

Safe and effective treatment of early suprahepatic inferior vena caval outflow compromise following orthotopic liver transplantation using percutaneous transluminal angioplasty and stent placement.

Purpose: To describe the safety and efficacy of percutaneous transluminal angioplasty and stent placement in patients presenting with suprahepatic inferior vena cava (IVC) outflow compromise in the early postoperative period following orthotopic liver transplantation.

Methods And Results: Between October 2002 and April 2009, 3 patients presented with IVC outflow compromise in the first 2 months following orthotopic liver transplantation. All 3 underwent percutaneous transluminal angioplasty and stent placement without complication and showed significant clinical improvement at short and intermediate term follow-up.

Transmyocardial revascularization: peril and potential.

Transmyocardial laser revascularization is a technique for the treatment of patients with chronic angina pectoris that is refractory to medical therapy and who are not eligible for surgical intervention. Percutaneous myocardial revascularization is a less-invasive catheter-based procedure that has been adapted from transmyocardial laser revascularization. Six prospective randomized clinical trials have been performed with transmyocardial laser revascularization and 5 have been performed using percutaneous myocardial revascularization.
