The aim of this work was to evaluate the efficiency, sensitivity, and specificity of ultrasonographic findings in the diagnosis of portal vein cavernous transformation and secondary splanchnic hypertension in children. Twenty patients with esophageal varices on endoscopic sclerotherapy, with ages ranging from 1 to 15 years (mean of 7.5), were compared with 20 age-matched normal asymptomatic controls. In 17 cases, diagnosis was confirmed by splenoportography. Ultrasonographic portal vein features, respiratory variations in splenic and superior mesenteric veins, lesser omentum to aorta diameter ratio and spleen size, as well as the presence of vessels in the lesser omentum and of spontaneous anastomoses, were analyzed in both groups. The efficiency of ultrasonography to establish a diagnosis of portal vein cavernous transformation reached 100%. Splenic and superior mesenteric vein respiratory variation was negligible in patients and inspiration versus expiration diameter differences ranged from 1 to 4 mm (mean of 2.4) in controls (p less than .001). Mean lesser omentum to aorta ratio was 2.07 in patients versus .9 in controls (p less than .001). Splenomegaly was found in all but two cases; lesser omentum vessels were visualized in nine cases; whereas five presented spontaneous splenorenal anastomoses and gallbladder varices were observed in five patients. Thus, ultrasonography allowed portal vein cavernous transformation to be diagnosed throughout; portal hypertension was also detected. It may be concluded that ultrasonography, either alone or associated with endoscopy, provides a reliable method for portal vein cavernous transformation diagnosis. Angiography should be reserved for preoperative or controlled hemodynamic studies.

“…Earlier studies of the liver in PHT have mainly been focused on demonstrating patency of the portal vein (7), and the existence of different collateral vessels such as a recanalized umbilical vein (12,14), a dilated coronary vein (8,15), or periportal, splenorenal or other collaterals (3,5,6,9) ..…”

Ultrasonographic Investigation of Respiratory Influence on Diameters of Portal Vessels in Normal Subjects

In order to improve the basis for ultrasonographic studies of portal hypertension the normal diameters and respiratory variations in the portal vessels were measured in sixty-seven volunteers. In healthy subjects, measurements were made on the portal vein and its major tributaries. The respiratory variations were most prominent in the splenic vein, somewhat less in the superior mesenteric vein and least in the portal vein. There were no significant correlations to weight, age or height. The hypothesis that examinations performed after food intake would give more prominent respiratory variations had to be rejected but showed that the portal vein should be examined under defined conditions regarding alimentary status. The diameters alone of the portal vessels can probably not be used reliably as an indicator of portal hypertension while a respiratory variation of less than 30 per cent in the splenic vein should be considered pathologic and lead to further investigations.
