Verification of clinical efficacy of surgical planning using 3D printed models of intracranial aneurysms: randomized controlled study

Not Applicable
Completed
Conditions
Diseases of the circulatory system
Registration Number
KCT0008646
Lead Sponsor
Seoul National University Hospital
Brief Summary

The usefulness of the model was determined based on treatment outcomes, patient counseling, and physician education. Compared to the control group, the total operation time was shorter (median 91 minutes versus 125 minutes; P = 0.02) and the volume of blood loss was lower (median 119.6 ml versus 234.0 ml; P = 0.01) in the case group. Patients’ understanding of the operation improved significantly after counseling using 3D printed models in all aspects (P = 0.02)
