Abstract

Cerebral embolic protection devices (EPD) reduce the rate of periprocedural thromboembolic complications and are currently used in all carotid artery stenting (CAS) procedures. However, tortuous vascular anatomy of the internal carotid artery (ICA) may prevent navigation of distal EPDs, thereby leading to inadequate cerebral protection. We present a case in which significant tortuosity of the ICA distal to the stenotic lesion precluded navigation of currently available distal EPDs. During a CAS procedure, significant vascular tortuosity of the distal cervical ICA was noted which prevented navigation of currently available distal EPDs due to catheter kinking. In order to overcome this anatomic barrier, a novel rapid exchange catheter system (RECS) was created using a modified DAC 038 braided catheter through which a distal EPD and microguidewire were placed. This newly devised RECS allowed navigation of the distal EPD past the tortuous ICA bend and successful completion of the CAS procedure without periprocedural complications. We demonstrate that modification of currently available devices can, in select cases, effectively address cases of significant vascular tortuosity which limit the use of conventional distal EPDs.
