%X BACKGROUND: Obesity is a serious situation that leads to non-communicable diseases like diabetes, hypertension, and others. The prevalence of obesity is growing very fast worldwide, so follow the results bariatric surgery, the most effective treatment of obesity, is increasing. Portomesentric vein thrombosis (PMVT) is one of the rare, fatal post-bariatric complications seen most commonly in sleeve gastrectomy and Roux-en-Y gastric bypass.
METHODS: A 50-year-old menopausal female with a body mass index (BMI) of 38 was admitted with acute abdominal pain 10 days after one-anastomosis gastric bypass (OAGB). Her lab tests were normal, but in her abdominal CT scan with IV contrast, subacute complete intraluminal thrombosis with luminal expansion at the left branch of the portal vein and its segmental branches was seen. Her diagnostic laparoscopy was normal, and she was discharged with no symptoms and a prescription for rivaroxaban.
CONCLUSIONS: PMVT is one of the complications after bariatric surgery that is very uncommon and fetal. It has been seen more in laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass, and early diagnosis of PMVT is essential due to its high mortality rate and cause of gastrointestinal ischemia.
CONCLUSIONS: In this case report, we saw that PMVT could happen after OAGB, and it is important to consider PMVT as one of the complications after OAGB to not miss the cases.
