Abstract

Objective: We report a case of neurofibromatosis type 1 with ruptured extracranial giant internal carotid artery (ICA) aneurysm, treated by endovascular trapping using a triple coaxial catheter system.<br>Case presentation: A 41-year-old female presented with dysphagia, and acutely appeared and enlarged left neck mass. Cerebral angiography, MRI, and contrast CT revealed ruptured extracranial giant ICA aneurysm. Since urgent treatment was necessary, endovascular coil-trapping was planned, considering the vulnerable aneurysmal wall. Initially, a microcatheter was easily kicked back and fallen down into the aneurysm during coil placement of the distal ICA. Next, we tried it with triple coaxial catheter system, using 4Fr inner catheter and balloon guiding catheter, which made the procedure of the distal and proximal ICA trapping stable and easy. Endovascular trapping was finished successfully and her symptoms were improved.<br>Conclusion: A triple coaxial catheter system was considered to be effective in endovascular trapping for treatment of a giant aneurysm with coils.
