Splanchnic vein thrombosis (SVT) is an uncommon presentation of acute thrombosis; however, it can have serious complications, including bowel or splenic ischemia, portal hypertension, and bleeding. Clinical features can vary from asymptomatic to nausea, vomiting, and/or severe abdominal pain out of keeping with physical examination. This chapter illustrates the presentation of acute SVT in the setting of inflammatory bowel disease (IBD). Risk factors for SVT include IBD, malignancy, intra-abdominal sepsis or surgery, intra-abdominal inflammatory states, thrombophillic conditions, and liver disease. The ideal imaging modality is abdominal computed tomography (CT). Anticoagulation is the primary treatment of choice in most cases of SVT.
