Arteriovenous malformations (AVMs) are the most dangerous congenital vascular malformations. Intracranial AVMs occur in about 0.1 percent of the population and account for 1 to 2 percent of all strokes. The angioarchitecture of AVMs consists of direct arterial to venous connections without an
The occurrence of complications of intracranial arteriovenous malformation (AVM) during labor induction is relatively uncommon. Intracranial AVM can cause convulsions, headache, focal neurological deficits and intracranial hemorrhage if ruptures. We present a 33-year-old parturient with history of
BACKGROUND
and purposes. The purpose of this study was to identify the specific characteristics of headaches associated with cerebral arteriovenous malformations in order to differentiate them from other known entities of headaches such as migraine, cluster headache, and trigeminal neuralgia. This
The therapeutic benefits of microsurgery for cerebral arteriovenous malformations (AVM) with regard to headache and epilepsy are not well known. The objective of the present review is to discuss the available evidence and our own experience, which showed that two-thirds of the patients with
OBJECTIVE
Cerebral arteriovenous malformations (AVM) are uncommon lesions. They are most often presented in childhood as intracranial hemorrhage. The aim of this report is to present the use of transcranial color-coded duplex sonography (TCCS) in detection of AVMs in children suffering
BACKGROUND
In ruptured and unruptured arteriovenous malformations (AVMs), bleeding and re-bleeding rate and efficacy of microsurgical, endovascular, and radiosurgical treatment to prevent hemorrhage are well known. Uncertainty exists concerning the benefit of therapy with regard to headache,
Cluster headache is considered a clinically distinct entity with no underlying gross pathology. However, in rare cases this kind of headache may be mimicked by an arteriovenous malformation. A 49-year-old male is described who had severe bouts of unilateral headache resembling those of cluster
Three women, aged 27, 32 and 30 years, respectively, suffered from headache, nausea and neurological abnormalities and were found to have an intracranial arteriovenous malformation (AVM). One of them after diagnosis had two pregnancies, both ended by caesarean section with good results. Another
89 patients with angiographically documented arteriovenous malformations were treated with helium ion Bragg peak radiation. The rate of complete angiographic obliteration 2 years after radiation was 94% in those lesions smaller than 4 cm3 (2.0 cm in diameter), 75% for those 4-25 cm3 and 39% for
Among all vascular malformations, the intracranial arteriovenous malformations (AVM's) have the most powerful impact from the clinical point of view. The manifestations include hemorrhage, seizures, headacheh, but sometimes they are incidentally found during the diagnostic approach of patients with
Intracranial arteriovenous malformations (AVM) are uncommon vascular lesions which typically present with hemorrhage or, in the case of unruptured lesions, with seizure, headache, or focal neurological deficit. The importance of the venous drainage pattern in AVM natural history and treatment
OBJECTIVE
The effectiveness and safety of radiosurgery for small- to medium-sized cerebral arteriovenous malformations (AVMs) have been well established. However, the management for large cerebral AVMs remains a great challenge to neurosurgeons. In the past 5 years the authors performed preplanned
