Portal venous gas complication following coronary angiography: A case report

Figure 1 Computerized tomography scan on February 21, 2024. A and B: No portal venous effusion seen.

Figure 2 Computerized tomography scan on February 26, 2024. A: Transverse section: Portal venous effusion, prominent in the left portal vein; B: Transverse section: intrahepatic portal vein, superior mesenteric vein, splenic vein, multiple pneumatoconiotics in mesenteric vessels; C: Sagittal view: Intrahepatic portal vein, superior mesenteric vein, splenic vein, multiple pneumatoconiotics in mesenteric vessels, and turbidity in the right middle and lower abdominal periampullary fat of the right middle and lower abdomen of the right middle and lower abdominals.

Figure 3 Emergency computerized tomography scan of abdominal aortic enhancement. A: Transverse section of the liver; B: Transverse section of the intestinal lumen; C: Sagittal view. A-C: Extensive pneumoperitoneum in the portal vein. Multiple scattered gas in the superior mesenteric vein and its collateral branches (right middle and lower abdominal peristomal vessels), turbid spaces of the right middle and lower abdominal peristomal fat, and a localised small bowel wall in the right lower abdomen; D: Reconstruction of the vascular image of the abdominal aorta: Localised calcified plaque in the abdominal aorta, compression syndrome of the median arcuate ligament, no embolism of the mesenteric artery.

Figure 4 Comparison of computerized tomography scan on February 26, 2024, with necrosis of the bowel wall, peripheral exudative accumulation of mesenteric edema progressing more than before, and additional abdominopelvic effusion. Superior mesenteric vein and its collateral vessels with multiple pneumoperitoneum have been absorbed compared to before, and intrahepatic portal vein pneumoperitoneum has been significantly absorbed compared to before. A: Transverse section of the liver; B: Transverse section of the intestinal lumen; C: Sagittal view.

Figure 5 Computerized tomography scan on 10 March, 2024: Wall and mesenteric edema of the terminal ileum were better than before, and pelvic fluid was absorbed. A: Transverse section of the liver; B: Transverse section of the intestinal lumen; C: Sagittal view.
