Color Doppler findings of gastric varices compared with findings on computed tomography

Abstract

Although color Doppler sonography is a useful, noninvasive modality for evaluating the hemodynamics of gastric varices, it falls short in visualizing the detailed hemodynamics of the inflowing and outflowing vessels of gastric varices in half of the patients when compared with computed tomography.

Evaluation of therapeutic effects on rectal varices using percutaneous color Doppler ultrasonography

“…Komatsuda et al reported the usefulness of CDU for the diagnosis of gastric and duodenal varices, 17 and we concluded that CDU was useful for evaluating of gastric varices. 18 There has been only one report of the diagnosis of rectal varices by CDU. 6 CDU can be performed simply, non-invasively and repeatedly before and after treatments of rectal varices.…”

Variceal Bleeding and Portal Hypertension: New Lights on Old Horizon

“…Sato et al [7] in Japan reported that the rates of detection of gastric varices, feeding vessels, and draining vessels with color Doppler in comparison with CT were 100 % vs. 100 %, 87.5 % vs. 100 %, and 75 % vs. 87.5 %, respectively. Color Doppler was not a good modality in comparison with CT for detecting inflowing and outflowing vessels from gastric varices.…”

Diagnosis and Endoscopic Treatments of Rectal Varices

“…ECDUS is useful for detecting rectal varices through color flow images, and it is a necessary tool for effective and safe EIS by calculating the velocity of blood flow in rectal varices (Fig.2). (20). CDUS cannot be performed successfully without a suitable acoustic window.…”
