Core Tip
Core tip: Six patients with portal vein tumor thrombus (PVTT) at hepatic hilum underwent electrochemotherapy (ECT), a new non thermal ablative technique. The follow-up ranged from 9 to 20 mo (median, 14 mo). In 2 patient, the follow-up computed tomography (CT) demonstrated complete patency of the treated portal vein. Three patients showed a persistent avascular non-tumoral shrinked thrombus at CT during follow-up. No local recurrence was observed in 5/6 patients. One patient, was lost to follow-up because of death from gastrointestinal hemorrage 5 wk after treatment. ECT seems effective and safe for curative treatment of PVTT at hepatic hilum.
