Insights
Pediatric cerebral arteriovenous malformations (AVM) are rare but can cause severe hemorrhage. Surgical and radiosurgical interventions offer good outcomes for most children with AVM, improving quality of life.
Area of Science:
- Neurology
- Pediatric Neurosurgery
Context:
- Cerebral arteriovenous malformations (AVM) represent a significant challenge in pediatric neurosurgery.
- This study reviews a substantial cohort of pediatric AVM cases over 18 years.
Purpose:
- To analyze the clinical presentation, treatment modalities, and outcomes of pediatric cerebral arteriovenous malformations (AVM).
Summary:
- The study identified 61 pediatric AVM cases, with hemorrhage being the most common presentation (7.7%).
- Surgical intervention was performed in 86.8% of cases, with stereotactic radiosurgery used in 2 instances.
- A high success rate (82%) was observed, with most patients achieving good or excellent results and a normal life, though some experienced sequelae or mortality.
Impact:
- This research highlights the importance of timely diagnosis and intervention for pediatric AVMs.
- It provides valuable data on the efficacy of various treatment strategies, guiding future clinical practice and improving patient outcomes.
Abstract:
A series of 61 cases of cerebral arteriovenous malformations(AVM) was observed in children under 15 years of age during the last 18 years; 7 concern infants under 12 months and more than 50% are children between 10 and 15 years old. Intra-cerebral hemorrhage was revealing in 45 cases (7.7%) and 12 patients were in comatose state at presentation; 8 children (1.1%) only presented epilepsy alone; 53 cases (86.8%) were operated upon and only one has had a partial removal; 2 children were cured by stereotactic radiosurgery; one child must be embolize and 5 children were not treated; 50 cases (82%) have a good or an excellent result with normal life; 7 cases (11.5%) have sequellae and only 4 children (6.5%) died.
