We report the case of a liver transplant patient who developed a biliary stricture 3 years postoperatively which was treated with an endostent. During endoscopic removal, the stent fractured and a portion of it lodged itself within the intrahepatic portion of a portal vein branch. The endostent fragment was retrieved percutaneously using interventional radiology techniques. Risk factors for endostent fracture and migration as well as various percutaneous retrieval methods are reviewed in this article.

Percutaneous transvenous closure of atrial septal defects (ASDs) has become feasible in recent years, as later-generation devices have largely overcome initial difficulties in device deployment and complication rates. The Amplatzer septal occluder (ASO) is one such device that we have used extensively and is, in our opinion, the most versatile and practical to use. It is capable of closing defects up to 40 mm in diameter via a relatively low-profile delivery sheath. More importantly, the ASO may be easily withdrawn into the sheath after deployment but prior to release, which is essential in safely closing difficult defects where successful positioning on the initial deployment is not guaranteed. In this article based on our experience, review of the literature, and communications with other operators, we describe the various problems encountered in closing atrial septal defects and make suggestions as to the best way of overcoming these difficulties.
