The limitations of traditional treatment methods, such as simple ligation of the external carotid artery, which does not cure the condition.

    Excision of giant orbital arteriovenous malformation combined with ligation of the external carotid artery: a case report · 2026 · DOI

  • Considering its distinct minimally invasive advantages, endovascular therapy represents a highly viable alternative to surgery for parotid cAVFs, though prospective, multi-center studies with rigorous comparative cohorts are warranted to establish formal clinical recommendations.

    Endovascular treatment of congenital arteriovenous fistulas in the parotid region using coils and absolute ethanol · 2026 · DOI

  • The coexistence of AVM and DVA is a rare neurovascular association. There is a lack of understanding of the imaging features and clinical implications of this association.

    Coexistence of a Hemispheric Developmental Venous Anomaly and Two Ipsilateral Arteriovenous Malformations: A Rare Neurovascular Association · 2026 · DOI

  • The study used a simulated model and an animal model, which may not fully represent human brain AVMs. The sample size of the animal model was limited to six pigs.

    Mechanistically driven transnidal hemodynamic manipulations enhance simulated endovascular transvenous treatments for brain AVMs · 2026 · DOI

  • The accumulating evidence supports the concept that bAVM is a dynamic and multifactorial lesion that can emerge and evolve through the interplay of somatic mutations, chronic inflammation, and hemodynamic stress. In particular, the discovery of somatic mutations within lesional ECs represents a major breakthrough in elucidating mechanisms of lesion formation and endothelial dysfunction.

    Advances in the Genetics and Molecular Biology of Brain Arteriovenous Malformations · 2026 · DOI

  • There are no previous reports of SDAVF presenting with symptoms solely contralateral to the shunt origin. The varied initial presentation of SDAVF often results in diagnostic difficulties and delayed intervention.

    Isolated contralateral radiculopathy in thoracic spinal dural arteriovenous fistula without myelopathy: illustrative case · 2026 · DOI

  • The meta-analysis was limited by the availability of data from the included studies. The study did not assess the quality of the individual studies included in the systematic reviews.

    Hemorragia cerebral asociada a alteplasa en accidente cerebrovascular isquémico: revisión de revisiones sistemáticas y metaanálisis · 2026 · DOI

  • The diagnosis of intraosseous AVMs is frequently missed due to nonspecific clinical presentation. Routine dental extraction may precipitate catastrophic haemorrhage.

    Post-Extraction Catastrophic Bleeding Revealing an Undiagnosed Arteriovenous Malformation: A Case Report · 2026 · DOI

  • First, CLOVES syndrome should not be viewed solely as a benign structural overgrowth disorder when major surgery is planned. The coagulation and thrombotic risks are systemic and potentially life-threatening, even when surgical sites are distant from the primary malformations.

    Case Report: When benign overgrowth turns fatal in CLOVES syndrome: underestimated perioperative risk · 2026 · DOI
