In patients with vein of Galen malformations, high-flow shunting decreases cerebral perfusion. By reducing or eliminating these shunts, transarterial embolization can improve cerebral perfusion and clinical outcomes. Quantifying pre- and postembolization shunt blood flow may help determine the optimal timing and efficacy of embolization and may provide prognostic information. The authors used magnetic resonance imaging noninvasive optimal vessel analysis as a novel modality to measure volumetric blood flow through vein of Galen malformation shunts in a neonate and an infant before and after transarterial embolization.

A Case of Radical Resection of Esophageal Basaloid Cell Carcinoma After Hemostasis by Transarterial Embolization.
Case Rep Surg

Department of Surgery, Ise Red Cross Hospital, 1-471-2 Funae, Ise City, Mie, Japan.
Esophageal bleeding management typically involves endoscopy but becomes challenging with large or hemorrhagic tumors, especially in cases of rare basal cell carcinoma. This malignancy, with a poorer prognosis than squamous cell carcinoma, often requires definitive surgery. A 78-year-old man with severe hematemesis underwent transarterial embolization (TAE) after failed endoscopic hemostasis for a middle thoracic esophageal tumor.

Objective: To develop and validate a computed tomography (CT)-based deep learning radiomics model to predict treatment response and progression-free survival (PFS) in patients with unresectable hepatocellular carcinoma (uHCC) treated with transarterial chemoembolization (TACE)-hepatic arterial infusion chemotherapy (HAIC) combined with PD-1 inhibitors and tyrosine kinase inhibitors (TKIs).
Methods: This retrospective study included 172 patients with uHCC who underwent combination therapy of TACE-HAIC with TKIs and PD-1 inhibitors. Among them, 122 were from the Interventional Department of the Harbin Medical University Cancer Hospital, with 92 randomly assigned to the training cohort and 30 cases randomly assigned to the testing cohort.
Endovascular treatment of carotid-cavernous fistulas in a medium-sized Scandinavian neurovascular center.

January 2025
Department of Neurosurgery, Haukeland University Hospital, Bergen, Norway.
Purpose: Carotid-cavernous fistulas (CCFs) are treated almost exclusively by endovascular techniques, but the frequency of treatments is limited in smaller centers. We analyzed all CCFs treated in our hospital to determine if high-quality treatment of CCFs can be provided in a medium-volume neurovascular center.
Methods: Retrospective quality-control cohort study.

The integration of robotic systems in image-guided trans-arterial interventions has revolutionized the field of Interventional Radiology (IR), offering enhanced precision, safety, and efficiency. These advancements are particularly impactful for acute conditions such as stroke, pulmonary embolism, and STEMI, where timely intervention is critical. Robotic platforms like the CorPath GRX and Magellan allow for remote navigation and catheter-based interventions, making it possible to extend specialized services to remote and underserved areas.

Background: Numerous studies have demonstrated limited survival benefits of transarterial chemoembolization (TACE) alone in the treatment of intermediate-stage hepatocellular carcinoma (HCC) beyond up-to-seven criteria. The advent of immunotherapy, particularly immune checkpoint inhibitors (ICIs), has opened new avenues for HCC treatment. However, TACE combined with ICIs has not been investigated for patients with intermediate-stage HCC beyond the up-to-seven criteria.
