Validation Analysis Of Intelligent Selection Of Flow Diverters Used In The Treatment Of Intracranial Aneurysms Based On Three-dimensional Image Data

ObjectiveTo verify the accuracy of a preoperative simulation software（UKNOW）for the treatment of intracranial aneurysms using flow diverters（FDs）based on three-dimensional rotational angiography（3DRA）data.MethodsBased on 3DRA data,the preoperative simulation software（UKNOW）was used to simulate the deployment of virtual FDs.The length and dimensions of virtual and real devices were compared.The deployment plan recommended by the UKNOW software was preliminarily used to complete implantations in the real world.During the experiment,experienced neurointerventional experts were responsible for supervising and judging information such as the length,dimension,and deployment location of the FDs.ResultsThis study retrospectively analyzed the data of 29 patients who received FD treatment.There was no statistical difference between the length of the real device and the virtual device（p = 0.6）.The dimensions of FDs recommended by the software were consistent with the dimensions used in 24 out of the 29 real cases.In four of the remaining five cases,neurointerventional experts found that the FD dimensions recommended by the software were superior to those were actually used.Thus,the accuracy rate for FD dimension recommendations by the UKNOW software was 96.6%（28/29）.Procedures performed in five cases using deployment plans recommended by the UKNOW software all achieved good postoperative results;the deployment positions of the device were reasonable,and all devices showed good wall adherence.ConclusionsThe UKNOW software can give a reasonable deployment plan of FD before surgery,and the results are safe and reliable.
