Iatrogenic embolization: complication of pediatric cerebral angiography
Insights
Iatrogenic cerebral embolization during angiography in children occurred at a similar rate as in adults but with milder clinical consequences. Angiographic appearance and outcomes differed, possibly due to technique and pediatric-specific factors.
Area of Science:
- Neurology
- Pediatric Radiology
- Vascular Imaging
Background:
- Cerebral angiography in pediatric patients carries a risk of iatrogenic embolization.
- Understanding the incidence and clinical impact of these events is crucial for patient safety.
Purpose of the Study:
- To investigate the incidence, clinical outcomes, and angiographic characteristics of inadvertent iatrogenic cerebral embolization in infants and children undergoing angiography.
- To compare these findings with those reported in adult populations.
Main Methods:
- Retrospective analysis of 3,731 consecutive angiographic examinations in pediatric patients.
- Identification and review of cases with inadvertent iatrogenic embolization of cerebral vessels.
Main Results:
- Fourteen cases (0.9% of patients, 0.4% of examinations) of iatrogenic cerebral embolization were identified.
- Clinical consequences were mild, with only one patient experiencing transient neurologic symptoms.
- Angiographic appearance of emboli differed from adult cases, potentially influenced by technique (general anesthesia with hyperventilation) and pediatric-specific factors.
Conclusions:
- Iatrogenic cerebral embolization in children undergoing angiography is infrequent and typically associated with mild clinical outcomes.
- Differences in emboli appearance and clinical response compared to adults warrant further investigation into pediatric cerebrovascular physiology and imaging techniques.
Abstract:
Fourteen cases of inadvertent iatrogenic embolization of cerebral vessels occurring in a consecutive series of 3,731 angiographies in infants and children were studies. The incidence of embolization(0.9% of all patients ond 0.4% of all angiographic examinations) was about the same as has been reported in adults, but the clinical consequences were much milder, only one patient having documented transient neurologic symptoms. Also the angiographic appearance of the emboli differed from those described in adults. These differences may in part be due to the technique (general anesthesia with hyperventilation) but also to different reactions towards ischemia and to different types of emboli in children.
