Background/objective: Oral malformations of the tongue are exceedingly rare. The aim of this study was to evaluate the effectiveness of individualized treatment for patients with vascular malformations of the tongue.
Methods: This retrospective study is based on a consecutive local registry at a tertiary care Interdisciplinary Center for Vascular Anomalies.
Background: Venous malformations tend to retain their slow-flow behavior, even in progressive disease or regression following therapy.
Objective: The aim of this study is to analyze the development of acquired hemodynamic relevant arterio-venous fistulae in patients with slow-flow malformations.
Methods: This study is a retrospective analysis based on a consecutive local registry at a tertiary care Interdisciplinary Center for Vascular Anomalies.
Article Synopsis
- The study aimed to test the effectiveness and safety of a new embolic agent made from ethylene vinyl alcohol (EVOH) for treating symptomatic peripheral arteriovenous malformations (AVMs).
- A total of 36 procedures were conducted on 21 patients, with a focus on evaluating the success of the embolization techniques and patient outcomes, including symptom relief and any adverse events.
- Results showed that 85.7% of patients experienced good angiographic results, with 90% achieving pain relief, indicating that EVOH is a safe and effective option for treating peripheral AVMs with a low incidence of adverse effects.
Bleomycin electrosclerotherapy in therapy-resistant venous malformations of the body.

Article Synopsis
- The study aimed to evaluate the effectiveness of combining reversible electroporation with bleomycin in treating patients with slow-flow vascular malformations that had not responded to prior treatments.
- A total of 17 patients, averaging 20.8 years old, underwent this new combined treatment method, displaying significant reductions in lesion size — an average decrease from 24.9 cm to 3.5 cm.
- Results indicated that after a few months, half of the patients were symptom-free, suggesting that bleomycin electrosclerotherapy could be promising for those with resistant venous malformations, though larger studies are needed for more definitive conclusions.
Purpose: To assess morphological and hemodynamic characteristics of peripheral vascular malformations on 3 T magnetic resonance imaging (MRI) including qualitative comparison of two fat-saturated sequences: short tau inversion recovery (STIR) and three-dimensional high-resolution volume interpolated gradient recalled echo (GRE).
Materials And Methods: During 9 months, 100 patients with suspected or known vascular malformations were prospectively assessed on a 3 T scanner using T2-weighted STIR and turbo spin echo (TSE), T1-weighted TSE, time-resolved contrast-enhanced magnetic resonance angiography (MRA) with interleaved stochastic trajectories (TWIST) and T1-weighted volume interpolated breath-hold examination (VIBE) after contrast enhancement. The analysis included signal behavior and morphologic and hemodynamic characteristics.
