Arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system. In most cases, the disorder may be asymptomatic. The objective of endovascular AVM treatment is set individually for each case upon consultations with a neurosurgeon and a neurologist. The endpoint of the treatment should consist in prevention of AVM bleeding in a management pr...

Despite the great capacity for the pediatric brain to recover from stroke, the morbidity and mortality in children who harbor an arteriovenous malformation (AVM) remains high. This study examines the clinical data and management experience with 132 patients with brain AVM from 1949 to 1989. Although the high tendency for a childhood AVM to present with hemorrhage (79%) remained constant for the...

The avermectins (AVM) are macrocyclic lactone derivatives produced by Streptomyces avermitilis, which have potent anthelmintic as well as insecticidal activities (Egerton et al., 1979; Ostlind et aL, 1979; Putter et al., 1981). These compounds consist of four major components (A~a, A:a, Bl~, B2a) and four minor components (A~b, AEb, Bmb, BEb) but it is presumed that all avermectins share a comm...

BACKGROUND Cerebral arteriovenous malformations (AVMs) are congenital masses of arteries and veins that appear to undergo an unclear "maturation" for many years. Using structured interviews, we compared developmental history of adult patients with AVM with a comparison group of patients with cerebral tumor or aneurysm. OBJECTIVE To determine whether a remote history of developmental abnormali...

The long-term outcomes of gamma knife surgery (GKS) in patients with posterior fossa arteriovenous malformations (AVMs) were retrospectively analyzed in 82 patients followed up for more than 5 years to evaluate the efficacy and safety. The median AVM volume at GKS was 0.95 cm(3). The prescribed dose to the AVM margin was median 18 Gy with 1-18 isocenters. The actual complete AVM obliteration ra...

Abnormal vaginal microbiota (AVM) or bacterial vaginosis (BV) might negatively impact reproductive outcomes of in vitro fertilization (IVF). However, before randomized controlled trials are initiated to investigate cause and effect, it is necessary to establish the optimal treatment for AVM. Metronidazole seems ineffective to treat the biofilm in AVM; thus, clindamycin could be suggested as a r...

OBJECTIVE To characterize clinical features of avian vacuolar myelinopathy (AVM) in American coots. DESIGN Case-control study. ANIMALS 26 AVM-affected American coots and 12 unaffected coots. PROCEDURES Complete physical, neurologic, hematologic, and plasma biochemical evaluations were performed. Affected coots received supportive care. All coots died or were euthanatized, and AVM status w...

Brain arteriovenous malformation (AVM) is an important cause of hemorrhagic stroke. The etiology is largely unknown and the therapeutics are controversial. A review of AVM-associated animal models may be helpful in order to understand the up-to-date knowledge and promote further research about the disease. We searched PubMed till December 31, 2014, with the term "arteriovenous malformation," li...

Background: The authors introduced a rare case of intracranial malignant melanoma. Case presentation: A 32 year-old male patient presented to the hospital with signs and symptoms commonly seen in the presentation of a hemorrhagic stroke. The patient was diagnosed as having an Arteriovenous Malformation (AVM) after a thorough history, physical examination and radiographic imaging were performed ...

We describe a case of a patient who presented with hematuria and was diagnosed with a renal arteriovenous malformation (AVM). Transcatheter arterial embolization subsequently was performed on this lesion multiple times. Follow-up imaging demonstrated that the AVM was masking an underlying, rapidly growing renal cell carcinoma (RCC). We describe the pathological and radiographic characteristics ...
