High flow arteriovenous malformation with transverse-sigmoid sinus stenosis and congestive venopathy mimicking DAVF.
Background: Arteriovenous malformations commonly present with hemorrhage, seizures, headache and other symptomatology. However, AVMs presenting as venous hypertension, owing to downstream stenosis/occlusion of venous sinuses, are very rare. This presentation is much more common in patients with dural AVFs.
Case description: We present a young lady with left frontal arteriovenous malformation with bilateral transverse-sigmoid sinus stenosis, presenting with features of venous hypertension, which was treated with surgical excision of AVM. This case demonstrates a rare example of AVM with co-existing venous sinus stenosis distal to the nidus.
Conclusions: High flow AVMs may co-exist with venous sinus stenosis or occlusion and lead to congestive venopathy. Treatment of AVM with surgical resection can be performed safely to relieve the hyper-dynamic venous congestion.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
