Following the significant advances in neuroradiology, it has been now recognized that an intracranial arteriovenous malformation (AVM) lesion and vascular aneurysm(s) might coexist more often than estimated before. A58-yearold female seen due to a subarachnoid hemorrhage (SAH) was subsequently shown to have an AVM lesion fed by the pericallosal frontopolar, M1 segment of the middle cerebral art...

A correlation between near-infrared atmospheric attenuation measurements made by the Atmospheric Visibility Monitor (AVM) at the Table Mountain Facility and airport surface weather observations at Edwards Air Force Base has been performed. High correlations (over 0.93) exist between the Edwards observed sky cover and the average AVM measured attenuations over the course of the 10 months analyze...

Uterine arteriovenous malformation (AVM) is defined as abnormal and nonfunctional connections between the uterine arteries and veins. Although the patients typically present with vaginal bleeding, some patients may experience life-threatening massive bleeding in some circumstances. The treatment of choice depends on the symptoms, age, desire for future fertility, and localization and size of th...

Two cases of patients with multiple peripheral aneurysms are reported ; four aneurysms arising from the left callosomarginal artery feeding an arterivenous malformation (AVM) in a 51year-old female and two aneurysms from the left posterior inferior cerebellar artery not associated with AVM in a 53-year-old female. In the former case , the AVM was partly thrombosed and the most distal aneurysm w...

BACKGROUND AND PURPOSE A new curative embolization technique with Onyx for selected small and medium-sized superficially located brain AVMs was developed, which consists of obliteration of the nidus, including incremental occlusion of the draining veins. We report our first clinical results. MATERIALS AND METHODS Between June 2008 and July 2011, 24 patients (7 women, 17 men; mean age, 41 year...

BACKGROUND AND PURPOSE KTS is a rare limb overgrowth disorder with slow-flow vascular anomalies. This study examines the presumed association between KTS and spinal AVMs. MATERIALS AND METHODS We performed a MEDLINE search of articles and reviewed textbooks of spinal diseases to study the association between KTS and spinal AVM. Our goal was to ascertain the basis on which the diagnosis of KTS...

Risk factors for anthelmintic resistance (AR) on bovine ranches were studied. Data were derived from a survey made to 50 ranch owners, who had conducted a faecal egg-count-reduction test. The questionnaire contained descriptors of bovine ranch management and nematode control. A case-control design study was undertaken and AR cases were present in 26 herds. Associations between the binary outcom...

Avermectin (AVM) and ivermectin (IVM) are potent pesticides and acaricides which have been widely used during the past 30 years. As insect resistance to AVM and IVM is greatly increasing, alternatives are urgently needed. Here, we report two novel AVM derivatives, tenvermectin A (TVM A) and TVM B, which are considered a potential new generation of agricultural and veterinary drugs. The molecule...

Cerebral aneurysms and arteriovenous malformations (AVM) are a common cause of stroke and cerebral hemorrage. Both are often discovered when they rupture, causing subarachnoid hemorrhage (SAH). SAH-induced vasospasm is mediated by enhanced vasoconstriction due to endothelin-1 (ET-1). We investigated whether endothelial cells (ECs) obtained from aneurysm and AVM express phenotypic and genotypic ...

Anemia is one of the most common causes of dizziness. Most chronic anemia is associated with gastrointestinal bleeding, such as peptic ulcers or cancer of various organs (1). Pancreatic arteriovenous malformation (AVM) is a rare cause of gastrointestinal bleeding (2). They are usually asymptomatic but may present with abdominal pain, portal hypertension in the absence of hepatopathy, or gastroi...
