Application of interventional therapy for 3D printing cerebral arteriovenous malformation model based on DICOM image fusion technology

Abstract

Objective To explore the clinical value of 3D printed cerebral arteriovenous malformation (AVM) model in interventional embolization therapy. Methods Retrospective collection of clinical data of patients with AVM who underwent interventional embolization at the Department of Neurosurgery, Zhongshan Hospital Affiliated to Dalian University from January 2016 to June 2019. Ten patients who were included in the preoperative routine imaging examination and constructed a 3D printed model were used as the test group, and 10 patients of the same level without the 3D printed model were used as the control group, to compare the size of the deformed vascular mass before and after embolization, the embolization rate, and the operation time etc. Results The difference in AVM size between the test group and its MRA/CTA was statistically significant (P 0.05). Conclusion 3D printing brain AVM model based on DICOM image fusion technology can display AVM anatomical structure features more directly and accurately, and has great clinical application value in clarifying AVM size, S-M classification, improving embolization effect and shortening operation time.
