Portal vein embolization: Cross-sectional imaging of normal features and complications

OBJECTIVE. The purpose of this article is to describe the role of cross-sectional imaging before portal vein embolization, the normal imaging findings after the procedure, and the imaging findings of postprocedural complications. CONCLUSION. With the increasing emphasis on aggressive resection of hepatic malignancies, portal vein embolization has evolved into a leading technique. Radiologists need to be familiar with the normal imaging findings after this procedure and with the imaging findings of postprocedural complications.
