在对疑有颈动脉狭窄病人的诊断中,作者对X线平片上观察到的颈动脉钙化的潜在意义进行了评价。本研究的目的是在颈动脉区X线平片所见颈动脉钙化与动脉狭窄严重程度之间建立可能的联系。 对160例(男111例,平均62岁;女49例,平均66岁)临床疑有颈动脉狭窄的病人拍颈动脉X线平片,并在同一血管区作静脉数字减影血管造影(IVDSA),还对其中108例的同一血管区作复式超声(DUS)。钙化的分类按105mm胶片上的形态学外观进行。钙化分为点状和线形(线形定义为从
In the diagnosis of suspected carotid stenosis, the authors evaluated the potential significance of carotid calcification observed on plain radiographs. The purpose of this study was to establish a possible link between carotid artery calcification and the severity of arterial stenosis seen on plain radiographs of the carotid artery. Carotid radiographs of 160 patients (111 male, mean age 62, 49 women, average age 66) with carotid artery stenosis underwent carotid artery radiography in the same vascular region for intravenous digital subtraction angiography (IVDSA ), But also for 108 cases of the same vascular area for duplex ultrasound (DUS). Calcifications were classified according to the morphological appearance on 105 mm film. Calcification is divided into points and lines (linear definition from
