Interest of a Simulated Procedure Performed on a Printed Model in the Endovascular Treatment of Carotid-sylvian Aneurysms (Anev3D)

Detailed Description
The indication of a primary preventive treatment by endovascular route will be posed in a multidisciplinary consultation meeting of neurovascular pathology for patients who have accidentally discovered a carotid-sylvian cerebral aneurysm (not ruptured).
During the treatment announcement consultation carried out by an interventional neuroradiologist taking place, generally less than a month, after the staff, the latter may propose the study to the patient. The investigator gives him the information letter. The patient will benefit from a reflection period of one week and will be contacted by telephone by the MERM to validate or not his wish to participate in the study.
The random selection of patients is carried out in consultation during the inclusion visit (consultation with the MERM). The pre-operative course will be carried out according to the usual scheme in the 2 groups. Unlike the control group (PPO-), the PPO+ group will have a parallel PPO (Pre-Planning Operative). The intracranial aneurysm embolization treatment procedure will then be performed in both groups.
The duration of the study is a maximum of 6 months per participant, including a maximum interval of 2 months between the inclusion visit and the treatment (usual coverage period between the treatment announcement consultation and the intervention) and 4 months of follow-up (end-of-study visit at M4).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: PPO +
Operational Pre-Planning + intracranial aneurysm embolization treatment
|
Using a 3D printer, printing of the patient's aneurysm from the segmented 3D images obtained during the initial assessment and thus allowing a simulation of the embolization procedure.
This pre-operative planning (PPO) carried out in real conditions aims to anticipate the possible complications that could be encountered on the same day of treatment.
