A presumed new radiological-pathological entity of atherosclerotic subintimal of the carotid artery is described. Subintimal hematomas were found in 12 of 50 (24%) carotid bifurcations during surgery for repeated transient ischemic attacks in a single hemispheric distribution; only 33% were associated with ulcerations. The typical angiographic appearance was a sharply marginated, rounded, eccentric filling defect located near the extracranial carotid bifurcation, although occasionally it may simulate a typical smooth or even ulcerated atherosclerotic plaque. Pathological mechanisms responsible for the hemorrhage into the atherosclerotic plaque resulting in the hematoma are discussed.
描述了一种推测的颈动脉粥样硬化内膜下新的放射学 - 病理学实体。在针对单次半球分布的反复短暂性脑缺血发作进行手术时，在50个颈动脉分叉中的12个（24%）发现了内膜下血肿；仅有33%与溃疡相关。典型的血管造影表现是位于颅外颈动脉分叉附近的边界清晰、圆形、偏心性充盈缺损，尽管偶尔它可能类似典型的光滑甚至溃疡型动脉粥样硬化斑块。讨论了导致动脉粥样硬化斑块内出血形成血肿的病理机制。
