穿支动脉病变的影像学评估在内囊预警综合征中的临床应用1例

Clinical application of imaging assessment of penetrating artery lesions in capsular warning syndrome:a case report

内囊预警综合征是脑缺血发作的一种特殊亚型,目前关于其发病机制仍然知之甚少。本文报道了1例内囊预警综合征患者,展现了穿支动脉的影像学评估在其诊疗过程中的临床应用,充分阐明了内囊预警综合征的可能机制为穿支血管的动脉粥样硬化性病变,其反复发作的特点可能与血管狭窄处原位血栓形成-溶解有关。这一病例为了解内囊预警综合征的发病机制及指导治疗提供了更多的依据。

Capsular warning syndrome(CWS)is a rare clinical syndrome characterized by recurrent and transient episodes of focal neurological deficits.Patients with CWS are at high risk of developing infarction.However,the exact physiological mechanism of CWS remains unclear.This paper presents an imaging assessment of penetrating arteries in the context of CWS using advanced time-of-flight magnetic resonance angiography and high resolution magnetic resonance imaging.This case reveals atherosclerosis of the lenticulostriate artery as a potential etiological factor contributing to CWS.
