Novel Real-time MRI Navigation Technology in the Treatment of Venous Malformation: A Case Report
-
摘要: 静脉畸形是一种常见的先天性血管发育异常, 血管内硬化治疗是其治疗的一线方案。对病灶进行准确穿刺是血管内硬化治疗的关键, 如穿刺有偏差, 很可能造成局部溃疡、坏死等并发症。本例静脉畸形患者在诊疗中应用了新研发的实时MRI导航技术, 顺利实现了对常规手段难以到达的深部病变进行硬化剂注射治疗的目标。本文通过对该病例的诊疗经过进行回顾, 以期为静脉畸形或其他软组织疾病的诊断与治疗提供借鉴。Abstract: Venous malformation is a common congenital anomaly of vascular development, and endovascular sclerotherapy is currently the first-line treatment for it. Accurate puncture of the lesion is the key to endovascular treatment. Any deviation is likely to result in local ulcers, necrosis and other complications. We described one case, in which a newly developed real-time MRI navigation technology was introduced and sclerotherapy was successfully performed for deep lesions that were difficult to reach by conventional methods. This article reviewed the treatment process of this case, in order to provide guidance and help for venous malformations and other soft tissue diseases in the future.作者贡献：周经纬、张紫旻负责收集资料，撰写论文；顾豪协助疏理撰稿思路；陈辉、胡丽负责提供技术支持，审阅论文；刘泓源、徐梓安负责收集、核对资料；杨希、林晓曦负责指导论文修订。利益冲突：所有作者均声明不存在利益冲突
