Recurrent Cerebral Arteriovenous Malformation in a Child : Case Report and Review of the Literature

Abstract

J Korean Neurosurg Soc 45 : [401][402][403][404] 2009 Arteriovenous malformations (AVM) are generally considered to be cured following angiographically proven complete resection. However, rare instances of AVM recurrence have been reported in both children and adults with negative findings on postoperative angiography. The authors present the case of a 12-year-old boy with recurrent AVM. The AVM was originally fed by the pericallosal arteries on both sides, and it showed changing patterns of supply at recurrence. The authors concluded that a negative postoperative angiogram is not necessarily indicative of a cure. Repeat angiography and regular follow-up examinations should be performed to exclude the possibility of recurrence, especially in children.

Influence of the combination of patient age and deep venous drainage on brain arteriovenous malformation recurrence after surgery

“…Although surgery is considered to be the most robust method of repair (in comparison with endovascular or radiosurgery), recurrence over time after an initial negative postoperative angiogram, particularly in children, has been reported. 2,3,5,7,9,11,12,15,16,[18][19][20][21]24,25,27,[30][31][32]35,[39][40][41] Case reports of recurrent brain AVMs after apparent curative surgery suggest that older patients are unlikely to develop recurrence. However, recurrences are not confined to pediatric cases.…”

A Case of Pial Arterio-Venous Malformation

“…But some people with brain AVM may experience signs and symptoms other than bleeding related to the AVM. 1 The origin of arteriovenous malformations remains uncertain, although they are thought to be congenital and perhaps involves dysregulation of vascular endothelium growth factor (VEGF).…”

Role of follow-up imaging after resection of brain arteriovenous malformations in pediatric patients: a systematic review of the literature

“…Thirty patients from 13 papers were included in this review (Tables 2 and 3). [1][2][3]6,7,17,19,[22][23][24]26,29,30 Mean patient age at initial presentation of AVM was 8.92 years (range 1-17 years). All patients experienced AVM recurrence, and 2 patients experienced 2 recurrences each (total of 32 recurrences).…”
