An obstructed biliary stent can act as a nidus, causing complications such as recurrent persistent cholangitis. It can also cause vascular complications (such as bleeding and the formation of pseudoaneurysms), perforate the liver capsule (causing biloma or abscess), or, in rare cases, cause intestinal obstruction or perforation. In this pictorial essay, we demonstrate various interventional radiology techniques for the treatment of biliary stent dysfunction in patients with obstructive biliary disease.<\/jats:p>","DOI":"10.1590\/0100-3984.2019.0141","type":"journal-article","created":{"date-parts":[[2021,2,3]],"date-time":"2021-02-03T18:27:43Z","timestamp":1612376863000},"page":"43-48","source":"Crossref","is-referenced-by-count":5,"title":["Percutaneous
