Diagnostic value of color-coded duplex sonography within the first hours following carotid artery reconstruction was investigated. We examined 15 out of 290 patients who developed neurologic symptoms after carotid endarterectomy. During the early postoperative period color-coded duplex sonography was associated with some problems. The investigation at this time was characterized by poor quality of B mode and color Doppler. It may be caused by deposition of air or bleeding. Differentiation of internal and external carotid arteries was difficult. When Doppler sonography of the reconstructed carotid artery was additionally performed, more accurate information was obtained. A normal reconstructed internal carotid artery was found in 8 patients, whereas 5 patients showed pathologic results (3 stenoses, 1 total occlusion, 1 embolisation). In patients with pathologic changes reoperation was immediately performed. Results of ultrasound investigations were proved by intraoperative findings. In 2 patients examination of the reconstructed internal carotid artery was impossible even by the combination of duplex and Doppler sonography. We conclude that color-coded duplex sonography in combination with Doppler sonography is a valuable method for investigations in the early postoperative period following carotid artery reconstruction.
研究了彩色编码双功超声在颈动脉重建术后最初几小时内的诊断价值。我们检查了290例颈动脉内膜切除术后出现神经症状的患者中的15例。术后早期彩色编码双功超声存在一些问题。此时的检查特点是B模式和彩色多普勒质量较差。这可能是由空气沉积或出血引起的。区分颈内动脉和颈外动脉很困难。当额外对重建的颈动脉进行多普勒超声检查时，可获得更准确的信息。8例患者重建的颈内动脉正常，而5例患者显示病理结果（3例狭窄、1例完全闭塞、1例栓塞）。有病理改变的患者立即进行了再次手术。超声检查结果经术中发现证实。即使联合使用双功超声和多普勒超声，仍有2例患者无法对重建的颈内动脉进行检查。我们得出结论，彩色编码双功超声联合多普勒超声是颈动脉重建术后早期进行检查的一种有价值的方法。
