LUI G, Andrea; PONIACHIK T, Jaime; QUERA P, Rodrigo  y  BERMUDEZ E, Cristián. Mesenteric vein thrombosis: clinical manifestations, treatment and outcome. Rev. méd. Chile [online]. 2005, vol.133, n.1, pp.17-22. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872005000100003.

Background: Mesenteric vein thrombosis (MVT) is uncommon and accounts for 5-10% of all mesenteric ischemic events. In 80% of cases, an etiologic factor is found. The clinical presentation varies and the diagnosis is made based on imaging studies. The treatment involves anticoagulation alone or in combination with surgery. Aim: To describe the clinical characteristics of patients with MVT. Patients and methods: Retrospective and prospective review of all cases with MVT, treated between 1995-2001. The clinical presentation, imaging studies, treatment and outcome were evaluated. Results: 29 cases of MVT were reviewed (14 females, age 56 ± 15 years). Twenty two patients (76%) had recognizable risk factors. The main symptoms were abdomianl pain (86%) and vomiting (55%). The diagnosis of acute mesenteric ischemia was suspected on admission only in 6 patients (21%). Thirteen patients underwent transabdominal color Doppler ultrasonography and the diagnosis was confirmed for 11 of these (85%). Twenty out of 24 patients (85%) studied with computed tomography, had positive signs of MVT. Twenty one patients (72%) recieved anticoagulation, 10 of whom also underwent surgery. Four patients (14%) received surgical treatment alone. Four patients were not treated. Seven patients (24%) died. Conclusions: MVT is difficult to identify. It is necessary to have a high degree of suspicion in patients who have risk factors. The diagnosis is made with imaging studies. The treatment consists of early anticoagulation and surgical intervention when indicated (Rev Méd Chile 2005; 133: 17-22)
