The Emergency Coil Embolization of Iatrogenic Injury to Carotid with Supraclinoid Pseudoaneurysm and Carotid Cavernous Fistula: A Case Report.
Carotid cavernous fistula infrequently occurs secondary to traumatic supraclinoid pseudoaneurysm of the internal carotid artery.
A thorough search through PubMed has given evidence of only seven reported cases of the condition.
CCF commonly occurs after head injuries, rupture of an aneurysm in the cavernous segment, or as a result of iatrogenic damage to the vessel during transsphenoidal surgery as in this case.
The cases that have been reported in the past have been treated using one of the listed
methods which are trapping, a combination of trapping and controlled embolization, and inserting a
thrombogenic agent into the site of aneurysm. Even though these procedures have a positive post-operative outcome, they had a great
impact on morbidity and mortality, thus, they are not applicable in all cases.
Alternatively, the endovascular treatment option has shown promising results, through the placement of coils with stents, or coils without stents in the treatment of dissection of great vessels, fistulas, and extra-cranial arterial pseudo-aneurysms, while maintaining a patent flow through the parent artery. This case report discusses a post-traumatic iatrogenic CCF after a supraclinoid pseudoaneurysm that was treated through the coiling of the aneurysm.
