Transcirculation Approach for Matricidal Carotid Cavernous Aneurysm: Not a Good Choice – A Case Report of Unsuccessful Endovascular Treatment of Matricidal Carotid Cavernous Aneurysm

Matricidal carotid cavernous aneurysm (CCA) is a rare and dangerous condition. The treatment failure of the endovascular approach like flow diversion, coiling, or stent-coiling is relatively high with considerable morbidity and mortality. The transcirculation approach is an alternative treatment option, but in case of matricidal CCAs, the results are not well documented in the literature. The authors present a complicated case of an unsuccessful transcirculation approach for matricidal CCA finally treated with sacrifice of the parent artery and high-flow bypass.
