Abstract

Background

Indications for carotid endarterectomy (CEA) and reduction of complications require evaluation of the plaque properties and location of the distal end of the plaque. High cervical location can be predicted from the anatomy of the vertebral body and mandibular bones and the locations of the posterior belly of the digastric muscle and stylohyoid muscle. Magnetic resonance (MR) imaging without contrast medium is useful for preoperative evaluation of the plaque, arteries, and bone characterization. However, no method for simultaneous evaluation of the muscle, plaque, arteries, and bone using MR imaging has been established.

Methods

Five patients with moderate or higher carotid artery stenosis underwent CEA in our institute. Noncontrast MR imaging/MR angiography and computed tomography (CT) angiography were performed before surgery in all cases. The fusion images of the muscle, plaque, arteries, and bone (M-PAB image) acquired from MR imaging/MR angiography, CT angiography, and the intraoperative view were compared.

Results

M-PAB image, CT angiography, and intraoperative view were acquired in all cases with no obvious differences.

Conclusions

M-PAB imaging using MR imaging without contrast medium is useful for preoperative evaluation of CEA. This method does not require contrast agents and avoids radiation exposure.

背景：颈动脉内膜切除术（CEA）的适应症和减少并发症需要评估斑块的特性和斑块远端的位置。高颈椎位置可根据椎体和下颌骨的解剖结构以及腹股沟肌后腹和花键肌的位置进行预测。不使用造影剂的磁共振（MR）成像可用于术前评估斑块、动脉和骨骼特征。然而，目前还没有使用磁共振成像同时评估肌肉、斑块、动脉和骨骼的方法：方法：五名中度或中度以上颈动脉狭窄患者在我院接受了颈动脉造影术（CEA）。所有病例均在手术前进行了非对比核磁共振成像/核磁共振血管造影和计算机断层扫描（CT）血管造影。对通过 MR 成像/MR 血管造影、CT 血管造影和术中观察获得的肌肉、斑块、动脉和骨骼的融合图像（M-PAB 图像）进行比较：结果：所有病例均获得了 M-PAB 图像、CT 血管造影和术中视图，且无明显差异：结论：使用不含造影剂的 MR 成像进行 M-PAB 成像可用于 CEA 的术前评估。这种方法不需要造影剂，也避免了辐射暴露。

期刊介绍： World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The journal''s mission is to: -To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care. -To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide. -To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients. Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
