Rupture from cavernous internal carotid artery pseudoaneurysm 11 years after trans sphenoidal surgery

Thomas Morrison

Carotid artery pseudoaneurysm is a rare complication of transsphenoidal surgery, usually diagnosed within 90 days post procedure. Pseudoaneurysm rupture may present with severe epistaxis or carotid cavernous fistula (CCF) with significant morbidity and mortality. We present a case of epistaxis from pseudoaneurysm rupture over a decade after transsphenoidal surgery. The pseudoaneurysm was treated with staged balloon-assisted coiling, endonasal mucosal flap repair and interval flow-diverting stent insertion. This case illustrates that pseudoaneurysms develop and rupture regardless of postoperative time course after transsphenoidal surgery, and the treatment complexities involving combined endovascular and endonasal techniques.
