AI Article Synopsis
- Acute mesenteric vein thrombosis (MVT) is a rare cause of acute mesenteric ischaemia, primarily affecting older adults, and is less common in younger individuals, with many cases lacking clear causes.
- A 27-year-old man experienced persistent abdominal pain, leading to imaging that revealed extensive thrombosis in his portal and mesenteric veins; after treatment, his condition significantly improved.
- Clinicians need to be aware of the possibility of MVT in younger patients to avoid misdiagnosis and ensure timely treatment.
Article Abstract
Background: Acute mesenteric vein thrombosis (MVT) accounts for only 2%-10% of all cases of acute mesenteric ischaemia, with an incidence rate of ~0.1% in Europe and the United States. It represents < 10% of mesenteric infarction cases and is seen predominantly in older adults. In younger individuals, MVT is uncommon, with 36% of cases having unidentified mechanisms and causes.
Case Summary: A 27-year-old man presented to the emergency department on February 29, 2024, with a chief complaint of intermittent abdominal pain for 3 day. He was previously in good health. As the abdominal pain was not alleviated by conventional treatment, an abdominal computed tomography (CT) scan was performed, which showed increased density in the portal and mesenteric veins. Further imaging, including portal vein ultrasound, mesenteric CT angiography, and enhanced abdominal CT, revealed widespread thrombosis of the portal vein system (including the main portal vein, left and right branches, proximal mesenteric vein, and splenic vein). After 10 day of thrombectomy and anticoagulation therapy, the patient's abdominal pain had improved significantly. Follow-up assessments indicated that portal venous blood flow had largely returned to normal. He was discharged on March 9, 2024. During a follow-up exam 2 months later, repeat abdominal enhanced CT showed that the previously detected thrombi were no longer visible.
Conclusion: Clinicians should remain vigilant for acute MVT in young patients presenting with abdominal pain, to prevent misdiagnosis of this fatal condition.

Background: The erector spinae plane block (ESPB) has been increasingly utilized for postoperative analgesia in thoracic, abdominal, and spinal surgeries. This study evaluated the postoperative analgesic outcomes of ESPB with nalbuphine as a ropivacaine adjuvant for lumbar trauma surgery.
Methods: This randomized double-blind clinical trial included 57 participants who underwent lumbar trauma surgery.

Objective: To evaluate the clinical efficacy and safety of ultrasound-guided rectus sheath block (RSB) in laparoscopic umbilical hernia repair with intraperitoneal onlay mesh (IPOM).
Methods: A total of 139 patients scheduled for laparoscopic umbilical hernia repair with IPOM were selected and randomly assigned to either the group receiving general anesthesia combined with bilateral rectus sheath block (Group GR, 71 patients) or the group receiving general anesthesia alone (Group G, 68 patients). We monitored the patients' heart rate (HR) and mean arterial pressure (MAP) at four time points: before anesthesia induction (T1), at the start of surgery (T2), during mesh fixation (T3), and upon removal of the laryngeal mask (T4).
