“…Ectopic varices: Ectopic varices can develop at any site, including duodenal, small bowel, colon, rectum, common bile duct, and peristomal, with duodenum ectopic varices are being the most frequent to bleed[ 25 , 28 ]. Many case reports have described the use of EUS for variceal bleeding at ectopic sites.…”

Endoscopic ultrasound (EUS) is one of the significant breakthroughs in the field of advanced endoscopy. In the last two decades, EUS has evolved from a diagnostic tool to a real-time therapeutic modality. The luminal gastrointestinal (GI) tract provides a unique opportunity to access multiple vascular structures, especially in the mediastinum and abdomen, thus permitting a variety of EUS-guided vascular interventions. The addition of the doppler and contrast-enhanced capability to EUS has further helped provide real-time visualization of blood flow in vessels through the GI tract. EUS-guided vascular interventions rely on standard endoscopic accessories and interventional tools such as fine-needle aspiration needles and fine-needle biopsy. EUS allows the visualization of various structures in real-time by differentiating tissue densities and vascularity, thus, avoiding radiation exposure. EUS-guided techniques also allow real-time microscopic examination after target biopsy. Furthermore, many necessary interventions can be done during the same procedure after diagnosis. This article provides an overview of EUS-guided vascular interventions such as variceal, non-variceal bleeding interventions, EUSguided portal vein (PV) access with the formation of an intrahepatic portosystemic shunt, and techniques related to diagnosis of GI malignancies. Furthermore, we discuss current insights and future outlook of therapeutic modalities like PV embolization, PV sampling, angiography, drug administration, and portal pressure measurement.

“…One should be mindful of the Doppler angle since, in cases where US waves are vertical to the longitudinal axis of the portal vein (which also applies to all other blood vessels), a false absence of blood flow may be observed. A long-standing thrombosis may result in the formation of a cavernoma, which usually engulfs the extrahepatic biliary ducts [14]. Important changes occur in the splenic circulation as the result of splenic congestion and histological remodelling, leading to the increased resistance to the arterial inflow, which is reflected in the increased resistive and pulsatility indices (RI>0.6 and PI>1) of the intraparenchymal branches of the splenic artery [15,16].…”

Ultrasound (US) is usually the first and most commonly used tool in the diagnostic algorithm for liver disease. It is widely available, non-invasive and offers a real-time assessment of the liver in several anatomic planes, using different US modalities such as greyscale imaging, Doppler, elastography and contrast-enhanced US. This multiparametric ultrasound (MPUS) provides more information of the examined structures and allows for a faster and more accurate diagnosis, usually at the point of care, thus reducing the requirement for some invasive and more expensive methods. Current data on the MPUS in hepatology are summarised in this review, mostly focused on its use for non-invasive staging of liver fibrosis, detection and classification of portal hypertension and oesophageal varices, prognosis in chronic liver diseases and characterisation of focal liver lesions (FLLs). Based on the available data, we propose practical algorithms for clinical use of MPUS in chronic liver disease and FLL.

Subtypes and clinical significance of common bile duct varices in portal vein thrombosis: diagnosis and follow-up by Doppler US and EUS

Abstract: While abdominal US and EUS are equally sensitive for detection of CBDV, EUS allows more precise determination of CBDV subtype. Patients with SMV might be at increased risk of bleeding upon ERCP.
