Pseudoaneurysm, Hepatic artery, Gastrointestinal bleeding, Pregnancy
A 29-year-old 11-week pregnant multigravida woman without previous medical history presentedwith sudden onset of hematemesis. This case illustrates the occurrence of a rare complication (rupture of pseudoaneurysm of right hepatic artery inside the biliary system), appearing as upper gastrointestinal bleeding in a pregnant woman. The cause of the rupture is presumably pregnancy-related. We would like to emphasize the presence of pseudoaneurysm of the hepatic artery as a rare cause of gastrointestinal bleeding in pregnancy.
Figure 1 and 2 CTA showed a lobulated contour of saccular aneurysmal dilatation at proximal right hepatic artery, measured about 3.5x3.2x1.6 cm in size and 2.6 mm in neck width; pseudoaneurysm is likely. There is perianeurysmal heterogeneously hyperdense non-enhancing lesion which shows flip-flop phenomenon, measured about 5.5x6.1x5.5 cm in size; Partially thrombosed pseudoaneurysm at proximal right hepatic artery is likely. This lesion causes stretching of the common hepatic artery and portal vein. Hyperdenselesion with flip-flop phenomenon is also seen within dilated bilateral IHD, CHD, CBD and gallbladder; Contrast extravasation into CHD, CBD, 1st, 2nd, 3rd, 4th part of duodenum and jejunum is detected in portovenous phase. hemobilia is suggested.
