Abstract
The aim of this study was to describe the case report of a 33-year-old girl with portal vein thrombosis. J.S.D.F., 33 years old, female, previously healthy, with a personal and family history negative for thromboembolic phenomena, without comorbidities, started with severe abdominal pain in the mesogastric region, radiating to HCD and back, associated with vomiting. Smoking active for about 20 years and using OC for 2 years. In view of the symptoms, she sought emergency services, where the first suspicion would be pancreatitis. Initial tests plagued leukocytosis. GUS of the total abdomen with doppler and CT of the abdomen showed the presence of thrombus in the right portal vein, with no other alterations. Rocefin® and metronidazole as an initial measure in the service began in addition to full coagulation with Clexane®. It showed clinical and laboratory improvement, with a reduction of leukocytes. The patient remained hospitalized in a hospital for 22 days to investigate the etiological cause. After of hospitalization, the patient was released with medical discharge, with guidelines for seeking the hematology service. During the investigation consultations, the results of the requested tests were negative for the diagnostic suspicions of nocturnal paroxysmal hemoglobinuria and chronic myeloproliferative disease. After 6 months of follow-up, she was discharged from the hematology service because she did not present a suspected disease and classified the cause of thrombolytic event as idiopathic associated with the combined use of OC and smoking.
Highlights
Portal vein thrombosis (PVT) is identified by portal venous obstruction caused by a blood clot
The etiologies of clot formation can be divided into four groups: direct lesion in the portal vein; congenital malformation of the vascular system with involvement of the portal system; indirect factors that influence the formation of the portal vein thrombus; and idiopathic causes (Balfour & Stewart, 1869)
GUS of the total abdomen with doppler and CT of the abdomen was requested, which showed the presence of thrombus in the right portal vein, with no other alterations
Summary
Portal vein thrombosis (PVT) is identified by portal venous obstruction caused by a blood clot. Balfour and Stweart (1869) described PVT in first time, being considered the main cause of extrahepatic portal hypertension in patients with normal liver (Belli, et al, 1989). Due to the recent diagnosis of more hereditary prothrombotic risk factors and the earlier detection of latent myeloproliferative syndromes, the rate of patients with idiopathic PVT has been reducing (Mahmoud, et al, 1997; Moreira, et al, 2009). Because it is a multifactorial disease, it is admitted that the simultaneous presence of more than one risk factor is necessary for venous thrombosis to occur (Okuda, et al, 1985). The aim of this study was to report the case of a 33-year-old girl with portal vein thrombosis
