A 35-year-old man suffered secondary generalized tonic-clonic convulsions due to a large brain abscess. Neuroimaging incidentally revealed another tumor-like lesion. Cerebral angiography confirmed that the lesion was an unusual giant venous varix associated with a high-flow pial arteriovenous fistula (AVF) and showed one more small arteriovenous malformation (AVM). Pulmonary AVF, which can caus...

PURPOSE To describe symptomatic pulmonary emboli from brain arteriovenous malformation embolization with liquid acrylates and to analyze the reasons for these complications and describe preventive techniques. METHODS The clinical records of 182 patients embolized with acrylate glue since 1978 for treatment of brain AVMs were searched for evidence of symptomatic pulmonary complications. Origin...

BACKGROUND Renal arteriovenous malformation is an aberrant vascular connection between the renal artery and vein. Acquired renal arteriovenous malformation (arteriovenous fistulae) accounts for approximately 70% of renal arteriovenous abnormalities. Congenital renal arteriovenous malformation, relatively rare, can result in significant hematuria which may require arterial embolization or nephre...

background: arteriovenous malformations are one of the most common vascular disorders of the colon. vascular disorders present as painless, high-volume rectal bleeding. case presentation: this study elucidates two rare cases of vascular disorders that are diagnosed as angiodysplasia of the left colon and cavernous hemangioma of the colon and rectum.  the chief complaint in two patients was rect...

INTRODUCTION Pregnancy has been linked to increased rates of arteriovenous malformation rupture. This link remains a matter of debate and very few studies have addressed the management of arteriovenous malformation in pregnancy. Unruptured arteriovenous malformations in pregnant woman generally warrant conservative management due to the low rupture risk. When pregnant women present with rupture...

Arteriovenous malformations (AVMs) can occur in any location but are more commonly seen the brain. Surgical excision combined with embolization therapy is preferred method of treatment. We had a young female intramuscular AVM left leg and patient has already undergone sclerotherapy multiple times not been relieved symptoms. have excised severely calcified stone-like AV malformation ligation fee...

This study is to investigate hematuria in pregnant patients caused by renal arteriovenous malformation and to evaluate the efficacy of superselective renal angiography and embolization used for treatment of renal arteriovenous malformation. Two cases of hematuria in pregnant patients caused by renal arteriovenous malformation were enrolled. Case 1 was a 28-year-old woman with repeatedly intermi...

BACKGROUND AND PURPOSE This review discusses recent research on the genetic, molecular, cellular, and developmental mechanisms underlying the etiology of vascular malformations of the brain (VMBs), including cerebral cavernous malformation, sporadic brain arteriovenous malformation, and the arteriovenous malformations of hereditary hemorrhagic telangiectasia. Summary of Review- The identificati...

The genesis of brain arteriovenous malformations remains enigmatic. We reviewed some pathways involving inflammatory and angiogenic signals that are amenable to the study of genetic single-nucleotide polymorphisms associated with the sporadic disease. Such study can yield insights into arteriovenous malformation pathogenesis and suggest possible fruitful approaches to developing medical therapy...
