Abstract
OBJECTIVE
The most common cause of hemorrhage after paracentesis is direct needle puncture of the inferior epigastric artery (IEA). This study examined the relationship between the amount of the ascites and the location of the IEA in liver cirrhosis.
METHODS
Abdominal computed tomography (CT) examinations of patients with liver cirrhosis were reviewed retrospectively and divided into two groups according to the amount of ascites. The distances between the midline and the IEAs of both sides were measured at the umbilicus, McBurney's point, anterior superior iliac spine, and mid-inguinal level. Branching of the IEAs, abdominal wall and mesenteric varices in the abdomen below the umbilicus level were recorded.
RESULTS
A total of 120 abdominal CTs were reviewed. The distances from the midline to the IEA in the large ascites group were longer than those in the small ascites group at the level of the right McBurney's point (44.5±14.6 mm vs. 39.6±11.8 mm, P=0.043) and left McBurney's point (48.6±15.3 mm vs. 43.3±11.5 mm, P=0.035). The incidence of abdominal wall varices was higher in the large ascites group (21.7% vs. 5.0%, P=0.014).
CONCLUSION
In patients with liver cirrhosis, the large amount of ascites might be associated with lateralizing the location of the IEA. Moreover, it may be necessary to confirm the blood vessels in the abdominal wall and mesentery near the puncture site by bedside ultrasound before the paracentesis.
