Cerebral hyperperfusion during surgical resection of high-flow arteriovenous malformations.
Cerebral hemodynamics were evaluated in 16 patients with arteriovenous malformations (AVMs) using intraoperative thermogradient or laser Doppler flowmeter. The postexcision/preexcision blood flow ratio was determined. Two of seven patients with large AVMs (> or = 4 cm) developed a postoperative hematoma. Their flow ratios were larger than 1.9. In 4 patients with large AVMs, their blood flow rat...

Arteriovenous malformations of the brain are congenital vascular lesions that affect 0.01-0.50% of the population, and are generally present in patients aged 20-40 years. The usual clinical presentations are haemorrhage, seizures, progressive neurological deficit, or headache. Results of natural history studies have shown a yearly haemorrhage rate of 1-4%.

Th e prevalence is calculated 0.2-0.5%/100.000 although lower numbers are discussed (0.01%) Men are slightly more aff ected than women (1.4:1) [1]. Most patients present with the neurological sequelae of intracranial haemorrhage caused by the AVM (50%), which is a major cause of intracerebral bleeding in younger adults. In 25% patients present with epileptic seizures and in 25% with other sympt...
