Abstract
AIMS: The aim of this study is to describe the outcome and management of all children who have presented with haemorrhagic stroke (HS) secondary to an arteriovenous malformation (AVM) at a single UK centre over a 13-year period. METHODS: All children with HS managed at our institution (2005-2018) were identified and those with underlying AVMs were studied. Clinical and imaging data were obtained from medical records. Outcome was scored using the Recovery and Recurrence Questionnaire. RESULTS: Ninety-three children (median age 8.8 years; 56 males; 8 neonates) presented with both global and focal features (28 had Glasgow Coma Score < 8). Haemorrhage was intraparenchymal in 72; prior risk factors present in 14. An underlying vascular lesion was identified in 68/93, most commonly AVM (n = 48). A systemic cause was found in 10, cerebral venous thrombosis in three, and 9 remain unidentified despite neuroradiological investigation. Median follow-up was 2.4 years, six died, and one was lost to follow-up. Outcome was rated as good in 60/86. Of the 48 AVMs, 3 were Spetzler-Martin (SM) grade 1, 21 SM 2, 21 SM3 and 3 SM4. One patient was treated conservatively as the AVM was too high risk to treat. At follow-up, 19 with AVM were angiographically cured, all with low SM grade and with the use of a single modality in 9 cases (all low SM grade). CONCLUSION: Although children with acute HS are extremely unwell at presentation, supportive care results in a good outcome in the majority. Complete obliteration for childhood AVMs is challenging even with low-grade lesions with multimodal treatment.
