Title: Ruptures of arteriovenous malformations in children associated with trivial head trauma. Author: Nishi T, Matsukado Y, Marubayashi T, Masumitsu T, Yamamoto H. Journal: Surg Neurol; 1987 Dec; 28(6):451-7. PubMed ID: 3686326. Abstract: Three cases of ruptured arteriovenous malformations (AVMs) in childhood associated with trivial head trauma are reported. These patients represented 12.5% of 25 consecutive patients with cerebral AVMs. The patients' ages ranged from 5 to 9 years; the patients were younger than their nontraumatic counterparts. The force of the trauma was presumably received in an anteroposterior or posteroanterior direction in all cases. Hematomas accompanying the AVMs were located in the subcortical area of the parietal or temporal lobe and angiographically their feeding arteries were all from the anterior cerebral artery or middle cerebral artery. The possible mechanisms for the rupture of AVMs after trivial head trauma are discussed.[Abstract] [Full Text] [Related] [New Search]
