Intraoperative magnetic resonance imaging system (iMRIS) surgical theatre is a highly integrated operating room with an intraoperative magnetic resonance imaging (iMRI) designed originally for brain tumour surgery. Its use in neurointerventional procedures, particularly in the setting of endovascular coiling of intracranial aneurysms, has not been discussed in the literature to date. We present our initial experience about the safety and feasibility of iMRI to assess post operative complications and provide baseline imaging post coiling of intracranial aneurysms.
Consecutive patients who underwent iMRI between 2015 and 2018 were included in the study. Demographic, clinical details, endovascular technique and surgical outcomes were collected. Details of anesthesia during the procedure were also collected.
Fifteen patients underwent iMRI with MRA to assess post coiling status of their elective endovascular coiling of intracranial aneurysms. The mean age in this cohort was 61 years and 46.7% were male. No immediate complications were seen either from the endovascular procedures or from the iMRI. All iMRI scans were performed as planned with no aborted or truncated scans. The image quality of the iMRI/MRA was adequate to detect the residual aneurysm, if present. There was no residual aneurysm on the angiogram that were not detected on the iMRIs. Of the 15 patients, 10 were safely discharged the following day and other 5 were discharged 2 days after their surgery.
The iMRI is an advantageous tool which can be integrated into neurointerventional workflow resulting in early post peri-procedural feedback and potentially reduced post-operative hospital stay.
术中磁共振成像系统（iMRIS）手术室是一个高度集成的手术室，配备有最初专为脑肿瘤手术设计的术中磁共振成像（iMRI）。迄今为止，尚未在文献中讨论其在神经介入手术中的应用，特别是在颅内动脉瘤血管内栓塞治疗中。我们介绍了我们在评估术后并发症和提供颅内动脉瘤栓塞术后基线成像方面使用 iMRI 的初步经验。
本研究纳入了 2015 年至 2018 年间接受 iMRI 的连续患者。收集了人口统计学、临床详细信息、血管内技术和手术结果。还收集了手术过程中麻醉的详细信息。
15 例患者接受了 iMRI 和 MRA 检查，以评估其择期颅内动脉瘤血管内栓塞治疗后的状态。该队列的平均年龄为 61 岁，46.7%为男性。无论是血管内手术还是 iMRI 都没有立即出现并发症。所有 iMRI 扫描均按计划进行，没有扫描中止或截断。iMRI/MRA 的图像质量足以检测到是否存在残留动脉瘤。在 iMRI 上未检测到血管造影上存在的残留动脉瘤。在 15 例患者中，10 例患者于次日安全出院，其余 5 例患者于手术后第 2 天出院。
iMRI 是一种有利的工具，可以整合到神经介入工作流程中，从而提供早期术后围手术期反馈，并可能减少术后住院时间。
