Microvascular Plug Embolization of Anterior Spinal Artery Bearing Segmental Arteries Prior Aortic Stenting: Technique and Safety.

Purpose: This study aims to present our experience with superselective embolization of the anterior spinal artery-bearing segmental artery (ASAbSA) using a microvascular plug (MVP) during the minimally invasive segmental artery coil embolization (MISACE) procedure prior endovascular repair of the thoracoabdominal aortic aneurysms.

Methods: We retrospectively evaluated all MISACE procedures performed between May 2018 and July 2023, where MVP was deployed into an angiographically confirmed ASAbSA. Data were analyzed regarding interventional details, technical aspects, and safety protocols.

Efficacy and Safety of Local Liver Radioablation in Hepatocellular Carcinoma Lesions within and beyond Limits of Thermal Ablation.

Introduction: CT-guided interstitial brachytherapy (iBT) radiotherapy has been established in the treatment of liver tumors. With iBT, hepatocellular carcinoma (HCC) lesions can be treated beyond the limits of thermal ablation (i.e.

Outcome of bleomycin electrosclerotherapy of slow-flow malformations in adults and children.

Objectives: To evaluate the safety and clinical outcome of bleomycin electrosclerotherapy (BEST) for treating extracranial slow-flow malformations.

Methods: In this retrospective investigation of a multicenter cohort presenting symptomatic slow-flow malformations, patient records were analyzed with respect to procedural details and complications. A treatment-specific, patient-reported questionnaire was additionally evaluated, obtained 3-12 months after the last treatment, to assess the subjective outcomes, including mobility, aesthetic aspects, and pain, as well as the occurrence of postprocedural skin hyperpigmentation.

In vivo evaluation of tumor uptake and bio-distribution of 99mTc-labeled 1-thio-β-D-glucose and 5-thio-D-glucose in mice model.

Background: To investigate the capacity of Tc-labeled 1-thio-β-D-glucose (1-TG) and 5-thio-D-glucose (5-TG) to act as a marker for glucose consumption in tumor cells in vivo as well as to evaluate the biodistribution of 1-TG and 5-TG. We investigated the biodistribution, including tumor uptake, of 1-TG and 5-TG at various time points after injection (0.5, 2 and 4 h) in human colorectal carcinoma (HCT-116) and human lung adenocarcinoma (A549) xenograft bearing nude mice (N = 4 per tracer and time point).

Prognostic value of baseline MRI features in patients treated with thermal ablation for hepatocellular carcinoma.

Purpose: To investigate prognostic value of baseline MRI features for time-to-recurrence (TTR) and local recurrence in patients with early hepatocellular carcinoma (HCC).

Method: Baseline and follow-up images of 88 patients treated with thermal ablation followed by adjuvant sorafenib or matching placebo due to HCC within the phase II prospective randomized trial (SORAMIC) were included. Baseline MRI images were evaluated in terms of atypical enhancement (lack of wash-in or wash-out), lesion diameter, tumor capsule, peritumoral enhancement on arterial phase, intratumoral fat, irregular margin, satellite lesions, and peritumoral hypointensity on hepatobiliary phase.

Impact of adjuvant sorafenib treatment after local ablation for HCC in the phase II SORAMIC trial.

Background & Aims: The aim of the study was to evaluate the efficacy and safety of adjuvant sorafenib treatment compared with placebo in patients with hepatocellular carcinoma who underwent local ablation.

Methods: The SORAMIC trial is a randomised controlled trial with diagnostic, local ablation, and palliative sub-study arms. After initial imaging within the diagnostic study, patients were assigned to local ablation or palliative arms.

Multicentered analysis of percutaneous sclerotherapies in venous malformations of the face.

Objectives: To evaluate the safety and outcome of image-guided sclerotherapy for treating venous malformations (VMs) of the face.

Materials And Methods: A multicenter cohort of 68 patients with VMs primarily affecting the face was retrospectively investigated. In total, 142 image-guided sclerotherapies were performed using gelified ethanol and/or polidocanol.

Prognostic value of baseline imaging and clinical features in patients with advanced hepatocellular carcinoma.

Aims: To investigate the prognostic value of baseline imaging features for overall survival (OS) and liver decompensation (LD) in patients with hepatocellular carcinoma (HCC).

Design: Patients with advanced HCC from the SORAMIC trial were evaluated in this post hoc analysis. Several radiological imaging features were collected from baseline computed tomography (CT) and magnetic resonance imaging (MRI) imaging, besides clinical values.

Y-Stent-Assisted Coiling With Low-Profile Neuroform Atlas Stents for Endovascular Treatment of Wide-Necked Complex Intracranial Bifurcation Aneurysms.

Background: Y-stent-assisted coiling is one of the eligible techniques for the treatment of complex bifurcation aneurysms. In majority of previous literature, Y-stenting has been performed using stents that could be delivered through large profile microcatheters that are often difficult to manipulate during navigation through sharply angled side branches. Attempts to navigate with these large profile catheters might cause serious complications during Y-stenting procedure.

Preliminary Results of Stent-Assisted Coiling of Wide-Necked Visceral Artery Aneurysms via Self-Expandable Neurointerventional Stents.

Purpose: To determine technical feasibility and results of stent-assisted coiling of visceral artery aneurysms (VAAs) with self-expandable LEO PLUS neurointerventional stent.

Materials And Methods: In this retrospective study, 11 consecutive patients (mean age 61.9 y ± 8.
