Renal arteriovenous malformations (AVM) are abnormal communications between the intrarenal arterial and venous systems. These lesions may present with a wide range of signs symptoms, including hypertension hematuria. We report case 71-year-old woman incidentally diagnosis asymptomatic right renal AVM.

ARTERIOVENOUS MALFORMATIONS AVM Incidence Since only 12% of AVMs cause symptoms, the incidence of AVM in the United States is not fully known. The incidence is thought to be around 1 per 100,000, equaling 300,000 cases. As technology advances and early detection increases, these numbers may rise. The average age of AVM diagnosis is 33 years, with 64% being identified before age 40 (Greenburg, 2...

BACKGROUND Arteriovenous malformations (AVM) of the urinary tract are extremely rare. To the best of our knowledge, only three case of AVM of the ureter have been described in the literature so far. CASE PRESENTATION We present an additional, fourth case of an AVM of the ureter, clinically presented as asymptomatic haematuria and an obstructive process in the left ureter. Ureteroscopic evalua...

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...

 Abstract Background: The Gamma Knife Radiosurgery (GKR) is an established management option for Cerebral Ar-teriovenous Malformations (AVMS). Therapeutic benefits of radiosurgery for arteriovenous malformations are complete obliteration of nidus with minimal neurological deficit. Methods: Radiosurgery was performed between February 2003 and April 2010 at Kamraniye day clinic, Teh-ran, Iran, us...

Orbital arteriovenous malformations (AVM) are identified by abnormal high-flow connections between the veins and arteries, which often supplied branches of internal external carotid also with a nidus cellular stroma distributed vessels. rare among all congenital malformations. Pain, glaucoma, optic nerve ischemia compression retinal some causes enlarging orbital AVMs. Because nature these lesio...

background: radiation-induced molecular changes on the endothelial surface of brain arteriovenous malformations (avm) may be used as markers for specific vascular targeting agents. in this study, we examined the level of expression of platelet endothelial cell adhesion molecule-1 (pecam-1) on brain endothelial cell surface after radiation treatment, with the aim of targeting the radiation-induc...

uterine arteriovenous malformations (avms) are relatively rare disorders that can cause life-threatening vaginal bleeding. we describe three childbearing-age females, who had abdominal pain and heavy vaginal bleeding, and were diagnosed as uterine avm by color doppler and angiography. the patients received successful superselective transarterial embolization (tae) with n-butyl cyanoacrylate (nb...

Although arteriovenous malformations (AVM) occur frequently in digestive organs, pancreatic AVM is rare. The clinical symptoms of pancreatic AVM are variable and include gastrointestinal bleeding, abdominal pain, jaundice, portal hypertension, pancreatitis, and duodenal ulcer. However, choledochoduodenal or pancreaticoduodenal fistulas complicated with ascending infection and pancreatitis is ex...
