Portomesenteric venous thrombosis: A community hospital experience with 103 consecutive patients

Background: Portomesenteric venous thrombosis (PMVT) is uncommon but associated with ischemic bowel and mortality. Objective: The purpose of this study was to determine the occurrence of PMVT in a community setting and evaluate current diagnosis, treatment, and outcomes. Methods: Medical records of consecutive patients admitted to a community-based hospital diagnosed with PMVT were reviewed. Patients were divided into 2 groups: those diagnosed from 1997 to 2003 and those diagnosed from 2004 to 2009. Results: One hundred three patients were included. The proportion of chronic PMVT diagnoses increased in the recent group (14% in contrast to 44%, P =.001). Treatment was more common in acute in contrast to chronic PMVTs (70% in contrast to 48%, P =.035). The median length of stay decreased over time (6 in contrast to 3 days, P =.004). Three patients underwent surgical intervention. Overall, 30-day mortality was 17% and did not change over time. Conclusions: Diagnosis and treatment have changed with increased differentiation between acute and chronic PMVT; outcomes were similar. Surgical intervention was rarely necessary. Mortality is attributed to patient comorbidity rather than PMVT.
