We present the case of a balloon-assisted, stent-supported coil embolization of a basilar tip aneurysm. Initially, a balloon extending from the basilar artery into the right PCA was placed.3 However, even with a more proximal purchase, coils were found to impinge on the left PCA. Subsequently, a transcirculation approach was performed, where the left posterior communicating artery was utilized as a conduit for balloon support and the coils were embolized from the ipsilateral vertebral artery.1 However, after this transcirculation approach was completed, there was a coil tail extruding from the aneurysm. The balloon was then removed over an exchange wire and a horizontal stent advanced, spanning the entire neck of the aneurysm, eliminating the extruded coil.2The video can be found here: http://youtu.be/bMbtZoPnYvo.

Object. Intracranial stent placement combined with coil embolization is an emerging procedure for the treatment of intracranial aneurysms. The authors report their results using intracranial stents for the treatment of intracranial aneurysms. Methods. A prospectively maintained database was reviewed to identify all patients with intracranial aneurysms that were treated with intracranial stents. Ten lesions, including eight broad-based aneurysms and two dissecting aneurysms, were treated in 10 patients. Four lesions were located in the cavernous segment of the internal carotid artery, two at the vertebrobasilar junction, two at the basilar trunk, one at the basilar apex, and one in the intracranial vertebral artery. Attempts were made to place stents in 13 patients, but in three the stents could not be delivered. Altogether, intracranial stents were placed in 10 patients for 10 lesions. Results that were determined to be satisfactory angiographically were achieved in all 10 lesions. Two patients suffered permanent neurological deterioration related to stent placement. In two patients, the aneurysm recurred after stent-assisted coil embolization. In one case of recurrence a second attempt at coil embolization was successful, whereas in the second case of recurrence parent vessel occlusion was required and well tolerated. Conclusions. Intracranial stents can be a useful addition to coil embolization by providing mechanical, hemodynamic, and visual benefits in the treatment of complex, broad-based aneurysms.

From October 1993 to February 1998, intraaneurysmal embolization by endovascular treatment with detachable coils was performed for 41 cases of cerebral aneurysm. As a detachable coil, interlocking detachable coils (IDC) were used in the initial 15 cases and Guglielmi detachable coils (GDC) were used in the subsequent 26 cases. As for 15 cases treated with IDC, complete occlusion was performed in 9 cases, subtotal occlusion in 4 cases and partial occlusion in 2 cases. In one of the partial occluded cases, a coil compaction occurred 6 months after embolization. Distal emboli were recognized on CT after embolization in 3 cases, however, only one case was symptomatic. Intra-operative bleeding occurred in one case, but no obvious hemorrhage after coil embolization in any case. As for 26 cases treated with GDC, complete occlusion was performed in 18 cases, subtotal occlusion in 8 cases. In one case of basilar-tip aneurysm, a mild coil compaction occurred 6 months after embolization. Distal emboli were recognized on CT after embolization in 3 cases, however, only one case was symptomatic (minor stroke). No intra-operative bleeding and no obvious hemorrhage after coil embolization occurred in any case. From our experiences, treatment for poor-grade ruptured aneurysm is still difficult, but intra-aneurysmal embolization for cerebral aneurysms using detachable coils is possible and a useful alternative, especially for surgically difficult aneurysms. The results of treatment of aneurysm with GDC are much better than those with IDC, so the indications for intra-aneurysmal embolization with GDC might increase in the future.

Purpose Flat panel detector (FD)-equipped angiography machines are increasingly used for neuro-angiographic imaging. During intracranial stent-assisted coil embolization procedures, it is very important to clearly and quickly visualize stent shape after deployment in the vessel. It is necessary to quickly visualize stents by cone-beam computed tomography (CBCT). The aim of this study was to compare CBCTs at 10 and 20 s, and to confirm that this method is useful for neuro-endovascular treatment procedures. Materials and methods We treated 30 patients with wide-necked intracranial aneurysms with a flexible, self-expanding neurovascular stent and subsequent aneurysm embolization with platinum micro-coils. We performed the CBCT after stent deployment. We compared the 10 s and 20 s CBCTs, using the full width one-half maximum (FWHM) visualization. Results Accurate stent placement with subsequent coil occlusion of the aneurysms was feasible in all patients. Stent struts were clearly visualized on both 10 s and 20 s CBCTs. Importantly, 10 s CBCT can reduce the radiation dose by about 42%, compared with 20 s CBCT. Performing 10 s CBCT with a 14% dilution of the contrast medium may significantly improve image acquisition during stent-assisted coil embolization. Conclusions Reduced-dose, 10 s CBCT can visualize stents in clinical cases, while significantly reducing radiation exposure.
