Risk Assessment of Intracranial Aneurysm Remnants After Microsurgical Clipping Based on 3D-Digital Subtraction Angiography

Key Points

• The aim is to evaluate the incidence of intracranial aneurysm remnants after microsurgical clipping using 3D-digital subtraction angiography.
• Used 3D-digital subtraction angiography to assess aneurysm remnants after clipping.
• Analyzed the impact of various factors on the completeness of clipping.
• Identified risk factors associated with incomplete clipping.
• Found a higher incidence of aneurysm remnants than previously reported in literature.
• Preoperative aneurysm size is identified as a significant independent risk factor for incomplete clipping.
• Emphasized the need for close follow-up for cases with incomplete clipping.
