Atrial embolism caused by portal vein embolization: Treatment by percutaneous withdrawal and stenting

World J Hepatol. 2012 Dec 27;4(12):412-4. doi: 10.4254/wjh.v4.i12.412.

Abstract

Hepatectomy remains the only curative treatment for many primary and secondary liver cancers. Portal vein embolization (PVE) has been used to increase the volume of the future liver remnant and thus lower the risk of small-for-size syndrome and postoperative liver failure. This technique has proven its safety, with a low post-procedure morbidity rate. Here, we describe a very rare case in which a young patient suffered a glue embolism to the right atrial cavity following PVE in preparation for a major hepatectomy for colorectal metastasis. The foreign body was withdrawn from the heart with a femoral, percutaneous device and trapped against the wall of the femoral vein with a self-expanding metal stent. Our report shows that this previously unknown complication of PVE can be resolved without recourse to sternotomy and open heart surgery.
