“…Recently, Simón-Talero et al showed an association between the detection of PSs by computed tomography (CT) and magnetic resonance imaging (MRI) analysis and increased complications and mortality in patients with liver cirrhosis [9]. Several researchers have reported US to be particularly useful for the detection of PSs [10][11][12][13][14]. In general, however, the role of US in the detection of PSs, and especially its impact on disease characterization, remains insufficiently investigated.…”

This review focuses on ultrasonography (US) to diagnose patients with complications in portal hypertension. Clinicians first use US to evaluate patients with suspected portal hypertension, because US is quick, simple, and radiation free. US is necessary for grading and performing paracentesis for ascites. Doppler US-based detection of reverse splanchnic vein flow or the presence of a spontaneous portosystemic shunt is highly specific in patients with cirrhosis. Since it is important to estimate spleen size in patients with portal hypertension, spleen size is usually measured by US. Spleen volume can be more accurately measured with 3D-US. Estimation of viable residual splenic volume after partial splenic embolization should be limited to cases with total splenic volume less than 1000 ml. Portal vein thrombosis is often detected during the US examination performed when symptoms first appear or during the follow-up. Two-dimensional transthoracic echocardiography is an excellent noninvasive screening test in patients with pulmonary portal hypertension who can undergo it. By measuring the maximum and minimum diastolic blood flow velocities in the renal arteries using renal color Doppler US, the pulsatility index (PI) and resistive index (RI) can be calculated. The PI and RI in cirrhotic patients were significantly higher than those in healthy subjects and patients with chronic hepatitis, and showed a significant positive correlation with the Child-Pugh Score. In conclusion, US is an essential tool for the diagnosis and treatment of patients with portal hypertension.

“…Noninvasive, nonexpensive, harmless, and rapid techniques are ultrasonography [8,[44][45][46], real-transhepatic portography, improved by ultrasonically guided puncture, may be performed with little risk and time/pulsed Doppler ultrasonography (capable of determining the direction and rate of blood flow in large veins) is proved to be superior with regard to delineation of the portal venous system and esophageal varices [56,57]. In [17,47], color Doppler sonography, and duplex Doppler ultrasonography [21,[48][49][50]. Part of the course of the several studies, this procedure was reported to be successful in 96% of the examinations, visualizing collateral veins portocaval anastomotic vessels can be visualized by ultrasonography opposite the left adrenal gland and in the in 81% and varices in 69% of the patients with portal hypertension [56,57].…”

The aim of this paper is to describe and discuss, on the basis of a thorough review of the literature, the case of a 70-year-old woman with probable cirrhosis secondary to chronic hepatitis B and C, uncomplicated portal hypertension (without ascites, encephalopathy or bleeding varices), splenomegaly and hypersplenism, and an unusual, spontaneous, large splenorenal shunt and recanalization of the umbilical vein. The tortuous and varicose splenorenal shunt was diagnosed by abdominal ultrasound and CT investigations. A duplex Doppler ultrasonography evaluation was performed to study shunt flow direction and velocity. No gastroesophageal varices were identified on endoscopic examination. The clinical relevance of spontaneous splenorenal shunt, often associated with fundic gastric varices, is discussed.
