This event was captured based on literature review of an article titled, "endovascular removal of a balloon expandable superior mesenteric artery stent".It was reported that the index procedure in 2017 was to treat the superior mesenteric artery (sma).A herculink elite stent was implanted and on an unspecified date post implantation, the patient developed abdominal pain and a full rash.This prompted allergy testing which demonstrated cobalt and chromium reactivity.The patient then underwent an endovascular procedure for removal of the herculink elite stent using disposable biopsy forceps with balloon control to prevent distal embolization and a snare to secure the stent to the wire.The patient was discharged on clopidogrel and rivaroxaban on post-procedure day 2 with minimal abdominal pain and improved rash.Details are listed in the attached article.
