Clinical success was defined as the resolution of symptoms. Technical success was defined as > 50% patency of the previously thrombosed vessel, with restoration of antegrade filling of SMV branches confirmed by venography at the conclusion of the treatment, and resolution of bowel wall thickening at CT.
After the procedure, all patients were discharged on lifelong oral anticoagulation therapy (INR 2.5–3.5). Follow-ups were performed using CT at the moment of discharge, after 1 month, and then 1 year after treatment. Color Doppler ultrasound follow-ups were performed at 3 and 6 months after treatment, and subsequently yearly.
