Characteristic Sonographic Findings of Hepatic Erosion by Umbilical Vein Catheters

Abstract

A characteristic liver lesion can be seen on sonography with hepatic erosion by UVCs. Our study shows the importance of a high index of suspicion of UVC erosion into the liver in neonates with catheters positioned in the liver. When such neonates have abdominal distension, prompt abdominal sonograms should be obtained.

Hepatic laceration because of malpositioning of the umbilical vein catheter: case report and literature review

“…Hepatic injures are more severe than the other complications with a high risk for morbidity and mortality (Table 1) [7][8][9][10][11][12][13][14]. Lim-Dunham [9] and associates studied the characteristic sonographic findings of hepatic erosion by UVCs.…”

“…Lim-Dunham [9] and associates studied the characteristic sonographic findings of hepatic erosion by UVCs. They showed that all neonates had abdominal distension within 9 days of catheter placement, and in all of them, the UVC tip was located below the hemidiaphragm and superimposed over the liver.…”

“…Complications related to the liver have a high rate of morbidity and mortality, particularly in small premature newborns [7][8][9][10][11][12][13][14]. To the best of our knowledge, less than 4 articles describing hepatic laceration because of direct injury of the UVC have been reported by now [7][8][9][10][11]. Here, we present a newborn patient with hepatic laceration and intraabdominal hemorrhage secondary to the displacement of a UVC through the liver parencyhma.…”

“…Although a wide experience has been gained since its use was first described in 1947 [3], several mild to serious complications related to the UVC have been reported in the English literature [1,[4][5][6]. Complications related to the liver have a high rate of morbidity and mortality, particularly in small premature newborns [7][8][9][10][11][12][13][14]. To the best of our knowledge, less than 4 articles describing hepatic laceration because of direct injury of the UVC have been reported by now [7][8][9][10][11].…”

Liver Hematoma Presented as Midgut Volvulus Due To Medical Error: A Case Report

“…Hepatic injures are more severe than other complications with a high risk for morbidity and mortality (8). Lim-Dunham et al (9) studied the characteristic sonographic findings of hepatic erosion by UVCs. They showed that all neonates had abdominal distension within nine days of catheter placement, and in all of them, the UVC tip was located below the hemidiaphragm and superimposed over the liver.…”
