Acute mesenteric ischemia secondary to oral contraceptive-induced portomesenteric and splenic vein thrombosis: A case report

Figure 1 Computed tomography of the abdomen. A and B: Portal vein thrombosis, splenic vein thrombosis, and superior mesenteric vein thrombosis (red arrows); C: Ischemic small bowel loops (yellow arrows). PVT: Portal vein thrombosis; SVT: Splenic vein thrombosis; SMVT: Superior mesenteric vein thrombosis.

Figure 2 Follow-up computed tomography of the abdomen. A and B: Portal vein thrombosis and superior mesenteric vein thrombosis (red arrows); C: Ischemic small bowel loops (yellow arrows). PVT: Portal vein thrombosis; SMVT: Superior mesenteric vein thrombosis.

Figure 3 Follow-up contrast-enhanced computed tomography of the abdomen and total gastroenterography on day 15 after admission. A and B: Residual thrombotic material visible in the superior mesenteric vein (A) and portal vein thrombosis (B) on contrast-enhanced computed tomography (CECT); C: Collateral vessels (red arrows) on CECT; D: Ischemic intestinal loops (yellow arrows) on CECT; E: Total gastroenterography revealed ischemic intestinal loops (yellow arrows). PVT: Portal vein thrombosis; SMVT: Superior mesenteric vein thrombosis.

Figure 4 Follow-up contrast-enhanced computed tomography on day 31 after admission. A: No residual thrombotic material was visible in the splanchnic vein, with collateral vessels and reopened superior mesenteric vein (red arrows); B: Contrast-enhanced computed tomography revealed ischemic intestinal loops (yellow arrow) and dilated bowel segments. SMVT: Superior mesenteric vein thrombosis.
