Primary portal venous aneurysms are rare; however, they are the most common visceral venous aneurysms, and their pathogenesis is not fully understood. Complications include thrombosis, rupture, and mass effect on adjacent structures. The optimal management of these patients is not known. We describe a patient whose large (6-cm) portal vein aneurysm underwent complete spontaneous regression over several years of serial observation. To our knowledge, this observation has not been reported in the English literature
Case Details
Disease Location
Liver
Personal Characteristics
57 years old man, history of acute alcoholic pancreatitis and portal vein aneurysm,type ii diabetes mellitus, hypertension, hyperlipidemia, chronic obstructive pulmonary disease, aortic valve insufficiency, and nonischemic alcoholic cardiomyopathy,
Clinical Characteristics
Incidental finding of an asymptomatic 6-cm pva on computed tomography. Because he was asymptomatic and medically high risk, we elected for serial observation and aspirin therapy.
Remission Characteristics
During same year after diagnosis, pva measured 4.7 cm. Another follow-up CT scan 1 year later revealed complete regression of the pva with portal vein of 1.6 cm, remaining unchanged after 2 years.
Treatment & Mechanisms
Proposed Remission Mechanisms
Not discussed
Clinical Treatment
Serial observation and aspirin therapy.
