Insights
Extracranial internal carotid aneurysms are rare, especially in children. Endovascular stent placement offers a viable treatment option for pediatric patients when surgery poses significant risks.
Area of Science:
- Vascular Surgery
- Pediatric Neurology
- Interventional Radiology
Background:
- Extracranial internal carotid aneurysms are rare, affecting less than 1% of the population.
- These aneurysms pose risks for cerebrovascular events and neurological complications.
- Incidence is significantly lower in the pediatric population.
Observation:
- A 14-month-old infant presented with unexplained neck swelling.
- MR imaging confirmed an extracranial internal carotid aneurysm.
- Multidisciplinary consultation deemed endovascular repair the optimal approach due to the patient's age and surgical risks.
Findings:
- Endovascular repair with stent placement successfully excluded the aneurysm.
- This minimally invasive approach was chosen over surgery due to the patient's young age.
- Pediatric endovascular stent placement is a crucial option when surgical risks are high.
Implications:
- Endovascular techniques provide a safe and effective alternative for treating pediatric extracranial internal carotid aneurysms.
- This case highlights the importance of considering endovascular options in complex pediatric vascular cases.
- Further research into endovascular treatments for pediatric vascular pathologies is warranted.
Background:
Extracranial internal carotid aneurysms consist a rare pathology with an overall incidence less than 1% in the general population, and warrant treatment due to their association with cerebrovascular events and neurological complications. The incidence is even lower in the pediatric population.
Case Report:
A 14-month infant presented in our clinic with neck swelling of unknown origin, with subsequent MR imaging revealing an extracranial internal carotid aneurysm. Due to the patient's age and risk of surgical complications, the decision to proceed with endovascular repair with stent placement and complete exclusion of the aneurysm from the circulation was made, after multidisciplinary consultation.
Results:
In the pediatric population, pediatric population, endovascular stent placement can be considered at least as a last resort treatment when surgical access harbors significant risks or is impossible.
