Solitaire AB stent-assisted coiling embolization for the treatment of ruptured very small intracranial aneurysms

Abstract

Abstract. Recent advances in neuroradiological techniques have increasingly improved the diagnosis rate for very small aneurysms, particularly with the widespread use of three-dimensional cerebral angiography. However, the treatment of very small aneurysms remains a considerable challenge for neurosurgeons. Endovascular coiling has emerged as a potential treatment option for intracranial aneurysms. The aim of the present study was to evaluate the safety and efficacy of Solitaire AB stent-assisted coiling embolization for the treatment of ruptured very small intracranial aneurysms. This retrospective study included nine consecutive patients with ruptured very small intracranial aneurysms (≤3 mm) that underwent Solitaire AB stent-assisted coiling embolization. The aneurysms were located in the ophthalmic branch of the internal carotid artery (n=2), the posterior communicating branch of the internal carotid artery (n=4), the top of the basilar artery (n=1) and the middle cerebral artery (n=2). Solitaire AB stents were successfully implanted in all nine patients. Of the nice individuals, six patients exhibited complete occlusion at Raymond grade I and three patients exhibited occlusion at Raymond grade II. No aneurysm rupture was observed during the surgery. During the follow-up period of 8-13 months, no intracranial hemorrhage occurred. A total of seven patients underwent follow-up digital subtraction angiography at 5-10 months post-intervention. No recurrence of the aneurysms and no stenosis or occlusion of the parent arteries was observed. Therefore, Solitaire AB stent-assisted coil embolization was demonstrated to be a safe and effective treatment for ruptured very small intracranial aneurysms. The long-term efficacy of this technique may be improved by increasing the packing density around the aneurysmal neck and improving the hemodynamics.

Clinical and angiographic outcomes following endovascular treatment of very small (3 mm or smaller) intracranial aneurysm

“…Very small intracranial aneurysms (VSAs), also known as tiny intracranial aneurysms, refer to those of 3 mm diameter or smaller aneurysms. [ 1 – 3 ] Recent advances in neuroimaging, especially the three-dimensional (3D) cerebral angiography, have increasingly improved the diagnosis rate for VSAs. With advances in endovascular techniques, endovascular coil embolization of intracranial aneurysms is considered a valid alternative to surgical clipping.…”

Successful Hemostasis of Post-pancreaticoduodenectomy Arterial Bleeding by Placement of a Covered Stent for Coronary Arteries

“…In contrast, TAE to embolize the vessel proximal and distal to a common hepatic artery aneurysm is widely used in vascular interventional radiology, and this procedure has a significantly high survival rate compared with surgical hemostasis [8][9][10][11] . This difference could be because in open abdominal surgery, determination of the bleeding source is often difficult due to local inflammatory changes or postoperative adhesions, and the postoperative complication rate is also reported to be high 12) .…”

“…It can be completely recovered twice, and the stent hole is adjustable. The advantages of this stent are mainly a higher success rate for SAC of small-size aneurysms and a lower risk of postoperative thrombosis [11].…”
