两例进行性偏瘫患者密切跟踪每日临床检查。两例患者入院时CT扫描和CSF均正常。在这两种情况下，客观恶化发生在三个或更多的步骤超过四天，从轻微的手指笨拙发展到手臂的完全瘫痪。在这两种情况下，第二次CT扫描后一天出现偏瘫显示一个陷窝的放射冠上的内囊。在1例病例中，静脉数字减影血管造影显示进展过程中大脑中动脉通畅。在另一个病例中，经颅多普勒超声的系列研究记录了大脑中动脉的持续通畅。这两个病例表明，没有必要假设大脑中动脉短暂闭塞是进行性腔隙性梗死的基本机制。
Two cases of progressive hemiplegia were closely followed by daily clinical examination. In both, the CT scan and CSF were normal on admission. In both, objective aggravation occurred in three or more steps over four days, progressing from minor finger clumsiness to total paralysis of the arm. In both cases a second CT scan a day after appearance of hemiplegia demonstrated a lacune in the corona radiata just above the internal capsule. In one case an intravenous digital subtraction angiogram demonstrated patency of the middle cerebral artery during the course of the progression. In the other case, serial study with transcranial Doppler ultrasound documented the continued patency of the middle cerebral artery. These two cases demonstrate that it is not necessary to postulate transient occlusion of the middle cerebral artery as an essential mechanism for progressive lacunar infarction.
