Background and Aim: This study aimed at analyzing the demographic characteristics of the patients with non-traumatic intracranial hemorrhage, their angiographic results and the correlation between computed tomography (CT) scan and angiography findings. Methods and Materials/Patients: In a descriptive study, we retrospectively reviewed the records of the patients with non-traumatic intracranial...
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.
Objective: to describe our experience with pre-operative evaluation of intracranial vascular malformations using functional magnetic resonance (fmRi). Method: Assessment of eight patients with cerebral vascular malformations (seven arteriovenous malformations [Avm] and one cavernous malformation) referred for pre-operative fmRi mapping of the eloquent cortex. An oxygen level-dependent technique...
Pulmonary arteriovenous malformations (PAVMs), although most commonly congenital, are usually detected later in life. CASE REPORT We present a case of a 19-year-old woman with no previous history of AVM or telangiectasia, who presented dyspnea and hypoxia by massive left hemothorax in the 34th week of gestation. After emergent cesarean delivery, a chest computed tomography (CT) with i.v. cont...
OBJECTIVE To determine whether the risk of arteriovenous malformation (AVM) rupture is increased during pregnancy and puerperium. METHODS Participants included 979 female patients with intracranial AVM admitted to Beijing Tiantan Hospital between 1960 and 2010. Two neurosurgery residents reviewed medical records for each case. Of them, 393 patients with ruptured AVM between 18 and 40 years of...
Avian vacuolar myelinopathy (AVM) was recognized in 1994 as a cause of wild bird mortality when 29 bald eagles (Haliaeetus leucocephalus) succumbed to the disease at DeGray Lake, Arkansas (USA). The cause of AVM and its source remain undetermined despite extensive diagnostic and research investigations. Two years later, when AVM killed 26 eagles in the same area in Arkansas, it became apparent ...
We report a case of ruptured tectal arteriovenous malformation (AVM) that was demonstrated angiographically only after removal of an unruptured occipital AVM. A 57-year-old man presented with sudden onset of diplopia and tinnitus. Computed tomography revealed a small hemorrhage in the right tectum mesencephali with intraventricular hemorrhage. Magnetic resonance imaging and angiography disclose...
BACKGROUND Arteriovenous malformation (AVM) in the extracranial region is uncommon. The most common sites are cheek, ear, nose, and forehead in order of frequency in the extracranial region. Although the external ear is the second most common site for the extracranial AVM, AVM in the pretragal region has not been reported until now. METHODS AND RESULTS We reported a case of AVM in the pretrag...
The incidence of uterine arteriovenous malformation (AVM) is rare. However, it is clinically significant in that it can cause life-threatening vaginal bleeding. We report a case of a large uterine AVM with positive serum beta-human chorionic gonadotropin. A presumptive diagnosis was made; a uterine AVM accompanied by, early pregnancy or retained product of conception. Because this uterine AVM w...
BACKGROUND Cerebral arteriovenous malformation (AVM) is a vascular disease exhibiting abnormal blood vessel morphology and function. miR-18a ameliorates the abnormal characteristics of AVM-derived brain endothelial cells (AVM-BEC) without the use of transfection reagents. Hence, our aim was to identify the mechanisms by which miR-18a is internalized by AVM-BEC. Since AVM-BEC overexpress RNA-bin...
