Nomogram for predicting in-stent stenosis after pipeline embolization device treatment in patients with unruptured intracranial aneurysm: a multicenter model development and validation study

Key Points

• The aim is to develop a nomogram that accurately predicts in-stent stenosis after pipeline embolization device treatment for unruptured intracranial aneurysms.
• Multicenter model development using clinical data from patients treated with pipeline embolization devices.
• Validation of the nomogram's predictive accuracy across multiple centers.
• Identification of parameters influencing in-stent stenosis after treatment.
• The nomogram demonstrated high accuracy in predicting in-stent stenosis.
• It successfully identifies high-risk patients for developing stenosis after treatment.
• The findings suggest improved strategies for managing treatment based on risk assessment.
