Usefulness of C-stopper coil for neurointervention.
C-stopper coil (CSC) which are available for 0.018-inch inner diameter microcenter have been used for neurointervention such as transarterial embolization (TAE) of feeding artery. Although various shapes of pushable microcoils have been developed, microcoils are usually short to embolize the lesion and require lots of coils. The most specific feature of CSC is the extended length of 18 cm. To evaluate the usefulness of CSC, we reviewed our experience of CSC. Neurointervention using CSC was performed for 28 patients (31 treatments). Intervention procedures were TAE for dural arteriovenous fistula (AVF)(n = 15), transvenous embolization for dural AVF (n = 4), parent artery occlusion for cerebral aneurysm, dissection and carotid-cavernous fistula (n = 8), TAE for epistaxis (n = 2), and preoperative embolization for tumor (n = 2). CSCs were deployed with push technique through microcatheter. CSCs were successfully placed into the lesion namely feeding artery, venous sinus, parent artery of aneurysm, or dissection. There were no major technical complications resulting in morbidity. Postoperative course was uneventful. No recanalization of the occluded vessel occurred during follow-up. Use of CSCs was safe and feasible for embolization of cerebrovascular lesion.
