Distal medium vessel occlusions (DMVOs) are thought to cause as many as 25% to 40% of all acute ischemic strokes and may result in substantial disability amongst survivors. Although intravenous thrombolysis (IVT) is more effective for distal than proximal vessel occlusions, the overall efficacy of IVT remains limited in DMVO with less than 50% of patients achieving reperfusion and about 1/3 to 1/4 of the patients failing to achieve functional independence. Data regarding mechanical thrombectomy (MT) among these patients remains limited. The smaller, thinner, and more tortuous vessels involved in DMVO are presumably associated with higher procedural risks whereas a lower benefit might be expected given the smaller amount of tissue territory at risk. Recent advances in technology have shown promising results in endovascular treatment of DMVOs with room for future improvement. In this review, we discuss some of the key technical and clinical considerations in DMVO treatment including the anatomical and clinical terminology, diagnostic modalities, the role of IVT and MT, existing technology, and technical challenges as well as the contemporary evidence and future treatment directions.
远端中等血管闭塞(DMVO)被认为在所有急性缺血性卒中中占比高达25%至40%,且可能导致幸存者出现严重残疾。尽管静脉溶栓(IVT)对远端血管闭塞的效果优于近端血管闭塞,但在DMVO中,IVT的总体疗效仍然有限,不到50%的患者实现再灌注,约1/3至1/4的患者未能实现功能独立。关于这些患者机械取栓(MT)的数据仍然有限。DMVO中涉及的血管更小、更细且更迂曲,这可能与更高的手术风险相关,而鉴于处于风险中的组织区域较少,预期获益可能较低。技术上的最新进展已在DMVO的血管内治疗中显示出有前景的结果,且未来仍有改进空间。在本综述中,我们讨论了DMVO治疗中的一些关键技术和临床考量,包括解剖学和临床术语、诊断方式、IVT和MT的作用、现有技术、技术挑战以及当代证据和未来治疗方向。
