@entity3 in the liver derived from @entity14 rarely invade the portal vein macroscopically. Little is known about the clinical characteristics and outcome of surgical treatment in @entity1 with @entity5 thrombus in the portal vein. Medical charts of 142 consecutive @entity1 who underwent hepatic resection for colorectal metastasis were reviewed retrospectively. Of the 142 @entity1 , 4 (2.8%) had macroscopic portal vein invasion. The most prominent characteristic on preoperative imaging was segmental staining in the arterial phase shown by dynamic computed tomography (CT) or by CT arteriography. This finding was positive in all four of the @entity1 . All @entity1 underwent anatomic liver resection and were alive with no evidence of disease for an average of 52.3 months (range 21-102 months). @entity5 thrombus in the portal vein is rare with colorectal metastasis. It is accurately detected by CT by checking for signs of segmental staining. In this setting, anatomic major resection of the liver is essential for curative treatment.
