Introduction: Arteriovenous malformations (AVMs) are uncommon vascular lesions that can arise in any part of the body. Case Report: In this case study, we presented a huge AVM of the upper lip in a 70-year-old man that he noticed since 5years ago with slow growth in this period. Computed tomography angiography revealed a large AVM with feeders from the right...

A 41-year-old woman with a history of recurrent epistaxis presented with left hemiplegia, right gaze deviation, and dysarthria. Physical examination confirmed skin and lip telangiectasia (figure 1). Her son had pulmonary arteriovenous malformation (AVM). Her head CT and cerebral angiography revealed right parietal hemorrhage with parasagittal AVM (figure 2). Hereditary hemorrhagic telangiectasi...

Nasal arterio-venous malformations (AVM) are uncommon lesions. We present a rare case of huge, long standing AVM in the nasal area which was treated by angioembolization, followed by surgical excision and forehead flap reconstruction.

Abstract Introduction To evaluate the efficacy and safety of EST, particularly foamed STS 3% in treatment arteriovenous malformations (AVMs) a single specialist centre. Methods All patients with AVMs who underwent EST from 01 January 2015–31 December 2019 were retrospectively reviewed. Types AVM grouped into Schobinger's classification. ESTs performed either foam sclerosants (STS polidocanol), ...

A 53-year-old man presented with sudden onset left-sided weakness. His medical history included hereditary hemorrhagic telangiectasia with recurrent epistaxis. On examination, he was hypoxemic at rest and had left-sided flaccid hemiparesis. He was noted to have multiple lower lip telangiectasias (Figure 1). Computed tomography of chest revealed bilateral segmental and subsegmental pulmonary emb...

BACKGROUND AND PURPOSE Cerebral arteriovenous malformation (AVM) is a vascular disease that disrupts normal blood flow and leads to serious neurological impairment or death. Aberrant functions of AVM-derived brain endothelial cells (AVM-BECs) are a disease hallmark. Our aim was to use microRNA-18a (miR-18a) as a therapeutic agent to improve AVM-BEC function. METHODS Human AVM-BECs were tested...

Spontaneous regression of cerebral arteriovenous malformation (AVM) is a rare phenomenon, but its occurrence is an important consideration in treatment planning. A 58-year-old male was found to have a high-flow AVM of Spetzler-Martin Grade III. Before his scheduled treatment, the AVM ruptured with a large parenchymal hemorrhage. Following emergency decompressive surgery, a targeted embolization...
