Abstract

Pseudoaneurysm (PA) and carotid cavernous fistula (CCF) of the internal carotid artery (ICA) is an uncommon complication of endoscopic endonasal surgery that occurs in 1% of cases. We report on the successful placement of flow-diverting stents (FDS) to ICA pseudoaneurysm and caroticocavernous fistula caused by iatrogenic ICA injury for a pituitary adenoma in a 37-year-old female. After placement of the pipeline shield given a certain time, dual antiplatelet agents (DAPT) and follow-up angiogram verified complete aneurysm obliteration and effective endoluminal reconstruction of the injured vessel. In managing ICA pseudoaneurysms, the placement of flow-diverting stents is a viable vessel-sparing technique.
