Mycotic intracranial aneurysms (MIA) are a rare form of cerebrovascular pathology for which obliteration must be undertaken when they present with rupture or fail to respond to antibiotic therapy. Intracranial stents provide the unique ability to simultaneously preserve parent vessel integrity while obliterating the aneurysmal sac, but their use for the treatment of MIA has only been reported in a few instances for proximally located lesions. We report a patient with a MIA treated with endovascular stenting and review the literature for similar cases. Three case reports of four MIA treated with either stent monotherapy or stent-assisted coil embolization were identified. The clinical and radiographic features of each case were detailed. A 35-year-old with bacterial endocarditis from Streptococcus mitis was diagnosed with a ruptured 3 mm MIA of the pericallosal anterior cerebral artery after episodic diplopia. The MIA was successfully treated with stent-assisted coil embolization utilizing a Neuroform EZ stent (Stryker Neuroendovascular, Kalamazoo, MI, USA). Follow-up magnetic resonance angiography at 3 months demonstrated complete aneurysm obliteration, and the patient was neurologically intact. In the literature, a M1 segment middle cerebral artery MIA, bilateral cavernous carotid MIA, and a unilateral cavernous carotid MIA were also successfully treated with Neuroform, Helistent (Hexacath, Rueil-Malmaison, France), and SILK (BALT Extrusion, Montmorency, France) stents, respectively. We present the first patient with a pericallosal MIA treated with stent-assisted coil embolization. Proper treatment of the causative organism with antibiotics minimizes the risk of infectious seeding of the stent. Intracranial stenting may be safely and effectively utilized to treat select cases of MIA. 相似文献

Endovascular treatment of ruptured intracranial aneurysms 总被引:4,自引:0,他引:4

The Guglielmi detachable coil (GDC) is an important tool for the treatment of ruptured intracranial aneuryms by an endovascular
approach. This new device may be introduced under fluoroscopy into the aneurysmal sac through a microcatheter. When the coil
is judged well positioned, it can be detached with accuracy by electrolytic breakdown. The procedure is completed when a dense
coil packing is obtained. When vasospasm is present, papaverin infusion or angioplasty may be used by the endovascular approach
as well. Best results are achieved in cases of small aneurysm with small neck. The morbidity and mortality rates in the first
200 patients treated by GDC for a ruptured intracranial aneurysm were 4% and 1.5%, respectively. Complications are generally
related to rupture of the malformation by the endovascular device or to thromboembolic events. Despite these promising results,
further studies using larger numbers of patients are required to determine the exact role of these procedures in patient care.

Objectives
Endovascular stents have been widely used in intracranial aneurysm embolization. In this work, we compared the safety and long-term efficacy of stent-assisted coiling with those of conventional coiling for small posterior communicating artery aneurysms, aiming at a better understanding of the related safety and efficacy profiles.Methods
Between January 2008 and December 2011, 114 small PcomA aneurysms (defined as 3 mm ≤ maximum diameter < 10 mm in this study) in 108 patients were treated by endovascular treatment in our department. Patient demographics, aneurysm characteristics, angiographic results (initial and follow-up), and procedural complications were assessed.Results
Embolization was successfully performed in all the patients. Complications occurred in 7.4% of patients in both groups. There was no associated mortality. Based on initial post-procedural angiography, the rate of complete aneurysm occlusion, neck remnant and residual sac in the stented group were 37.9%, 24.1%, and 37.9%, while in the conventional group the figures were 42.9%, 48.2%, and 8.9%, respectively. The initial angiographic results were significantly better in the conventional group, compared with the stented group (P = 0.038). The follow-up results showed that the rate of improvement in the stented group was significantly higher (53.3% vs. 14.0%; P < 0.001) and the recurrence rate was significantly lower than that in the conventional group (4.4% vs. 3.02%; P = 0.001).Conclusion
Compared with conventional coiling, stent-assisted coiling of the small posterior communicating artery aneurysms does not increase the risk. Stents bear an advantage in reducing the recurrence rate, increasing progressive occlusion rate, and improving long-term prognosis in endovascular treatment of intracranial aneurysms. 相似文献18.
