Duplex Doppler sonography (DS) and color-flow Doppler sonography (FDS) are noninvasive diagnostic methods for the evaluation of a patient with suspected vascular disease of the abdomen. They represent a useful adjunct to realtime sonography in the identification of normal and variant visceral vascular anatomy. Aneurysms and pseudo-aneurysms of visceral arteries are readily differentiated from other cystic lesions. DS and FDS have a high sensitivity in the detection of portal vein thrombosis and stenosis. Both methods allow the observation and measurement of splanchnic hemodynamics in patients with chronic liver disease and portal hypertension. Hence, DS and FDS already play an important role in the pre- and postoperative assessment of patients undergoing liver or pancreas transplantation. The possibility that DS and FDS may enable discrimination between hypovascular and hypervascular tumors is under clinical investigation. FDS facilitates an excellent anatomic display of the abdominal vasculature and allows easy placement of the Doppler sample volume. Consequently, quantitative data acquired with DS are accomplished within short scanning times. However, the diagnostic impact of both modalities depends to a great extent on the experience of the investigator.
双功多普勒超声检查(DS)和彩色多普勒超声检查(FDS)是用于评估疑似腹部血管疾病患者的非侵入性诊断方法。它们是实时超声检查的有用辅助手段,可用于识别正常和变异的内脏血管解剖结构。内脏动脉的动脉瘤和假性动脉瘤很容易与其他囊性病变区分开来。DS和FDS在检测门静脉血栓形成和狭窄方面具有很高的敏感性。这两种方法都可以观察和测量慢性肝病和门静脉高压患者的内脏血流动力学。因此,DS和FDS在肝或胰腺移植患者的术前和术后评估中已经发挥了重要作用。DS和FDS能否区分低血管性和高血管性肿瘤仍在临床研究中。FDS有助于很好地显示腹部血管的解剖结构,并便于轻松放置多普勒取样容积。因此,用DS获取定量数据可在短扫描时间内完成。然而,这两种检查方式的诊断效果在很大程度上取决于检查者的经验。
