Objective: The purpose of this study was to evaluate the diagnostic performance of three-dimensional computed tomography angiography (3D-CTA) for arteriovenous malformations (AVMs) in the oral and maxillofacial region.
Materials And Methods: Sixty four-slice spiral CT angiography of oral or maxillofacial region was performed in 8 patients with surgically proven arteriovenous malformations. The morphologic features, size, location, boundary, and feeding and draining vessels of lesions were reviewed.
Results: AVMs in 5 patients were located in the soft tissues and 3 were in the mandible. CTA of all cases showed tangles of disorganized vessels with well-defined borders. The feeding and draining vessels were enlarged and tortuous. Four patients had bone involvement.
Conclusion: Sixty four-slice spiral CTA can accurately demonstrate the morphological characteristics of AVMs.

This case report discusses the case of a 74-year-old man who was diagnosed with hereditary hemorrhagic telangiectasia (HHT). The patient initially presented with right upper quadrant abdominal pain and was later diagnosed with cholangitis. Subsequently, heart failure was identified due to hepatic arteriovenous malformations.

Arteriovenous fistulas of the filum terminale are rare vascular malformations that predominantly affect males and can present with various neurological symptoms. In this study, we indexed previously published cases of filum terminale arteriovenous fistulas demonstrating that endovascular and microsurgical management are both proven to be appropriate and successful treatment modalities with low complication rates. Endovascular treatment is far less invasive; however, it is associated with higher failure rates, which need to be managed surgically.

Gastroenterology and Hepatology, St. Joseph's University Medical Center, Paterson, NJ, USA.
Heyde syndrome is a triad of aortic stenosis (AS), gastrointestinal (GI) bleeding from angiodysplasia, and acquired von Willebrand disease (vWD). It is hypothesized that stenotic aortic valves cleave von Willebrand factor (vWF) multimers, predisposing patients to bleeding from GI angiodysplasias. This hypothesis is supported by the observation that aortic valve replacement often leads to the resolution of GI bleeding.

Wyburn-Mason disease (WMD) is a rare congenital phakomatosis known for its complex arteriovenous malformations (AVMs) predominantly affecting the brain and ocular structures. We present the case of a 19-year-old female with an unruptured Spetzler-Martin grade 5 left thalamic AVM, who initially exhibited progressive visual impairment and migraines. Following diagnosis, she was treated with trametinib, a MEK inhibitor; however, nine months later, she developed acute complications, including left monocular blindness and right hemisensory loss.
