Arteriovenous malformations (AVM) have a wide range of clinical presentations. Operative bleeding is one of the most hazardous complications in the surgical management of high-flow vascular malformations. In the cervical region, the presence of vital vascular structures, such as the carotid artery and jugular vein, may increase this risk. This is a case of massive arteriovenous malformation def...

Cerebral arteriovenous malformations (AVMs) are associated with hereditary hemorrhagic telangiectasia (HHT). I report a case of a patient with HHT with four cerebral AVMs in whom one AVM spontaneously regressed during a 5-year period. The spontaneous regression of this AVM in this patient with HHT supports the theory that AVMs associated with this syndrome have a different natural history than ...

Colonic arteriovenous malformations (AVMs) are well recognized in the literature and commonly manifest as colitis, abdominal pain, rare cases have been reported of liver congestion. Dual-supply superior artery/ inferior mesenteric artery (SMA/IMA) colonic AVMs never only one case treating portal hypertension due to an AVM with endovascular approach has reported. We present a dual-supply SMA/IMA...

Abstract Background Spinal arteriovenous malformations (AVM) consist of a heterogeneous group pathological vascular entities that affect the spinal cord parenchyma either directly or indirectly. Case presentation We present an unusual case malformation (type 2) in 18-month-old girl who presented with weakness both lower limbs and urinary incontinence. She was diagnosed AVM large intramedullary ...

INTRODUCTION Arteriovenous malformations (AVM) of the brain have a low prevalence but are responsible for a significant component of visual pathology in the young population. Vascular studies using selective angiography are necessary to identify arterial connections and venous drainage, and provide useful information for planning treatment. CLINICAL CASE A 10-year-old child with a temporo-occ...

In this report, the authors discuss the case of a patient with a mixed cerebrovascular malformation in which an arteriovenous malformation (AVM) was associated with a capillary telangiectasia. Recent reports have contained reviews of various subsets of mixed malformations. To the authors' knowledge, however, this is the first report of a mixed vascular malformation with both arterial and capill...

Angiography is the gold standard for the diagnosis and complete resection of arteriovenous malformations (AVMs). The absence of residual AVM after surgery is commonly believed to reduce the risk of future hemorrhage. However, AVMs can recur after proven complete angiographic resection can occur, albeit rarely, especially in the pediatric population. We report a rare case of a recurrent AVM two ...

Intracranial arteriovenous malformations (AVM) are a rare feature of Bannayan-Riley-Ruvalcaba syndrome (BRRS). Palencia et al reported a case of intracranial arteriovenous malformation in a child with BRRS in a Spanish journal in 1986. However, the occurrence of dural AVM in a patient with BRRS has not since been addressed in the literature. Advancements in imaging and therapeutic embolization,...

Cerebral vascular malformations with potential surgical consequences mainly consist of arteriovenous malformations (AVM) and cavernous malformations. The standard preoperative workup of these lesions includes basic neuroradiological investigation, such as computed tomography, magnetic resonance imaging (MRI), and magnetic resonance angiography, and conventional angiography, to assess the exact ...
