Advance Access: NeuroForm Atlas Stent-Assisted Coiling: Preliminary Results. Golshani K, Ferrel A, Lessne M, Shah P, Chowdhary A, Choulakian A et al. Neurovascular stents for stent-assisted coiling (SAC) offer a non-surgical, minimally invasive method to treat aneurysms in the brain. Bending expectations of conformability and stability The Neuroform Atlas Stent System is purposefully designed to provide the coil support and wall apposition needed to perform effective stent-assisted coiling procedures. CONCLUSIONS: Stent-assisted coiling of intracranial aneurysms is safe, effective, and provides durable aneurysm closure. EP stents were used for aneu - rysms arising from a parent vessel with a diameter of 2. However, the use of Solitaire AB stents for the treatment of ruptured very small intracranial aneurysms has not been reported in the literature. SAC is believed to be associated with a high risk of thromboembolic and hemorrhagic complications in acute subarachnoid hemorrhage (SAH). Neuroform Stent-Assisted Coil embolization to treat complex cerebral aneurysms over 3-year period, emphasizing on the technical difficulties, procedure-related complications, and to evaluate midterm results. Stent-assisted coiling of ruptured intracranial aneurysms, however, is not as widespread and remains somewhat controversial due to the possibility of thrombotic complications and the consecutive need for dual anti- platelet therapy in the presence of an acute subarachnoid hemorrhage. Overall, 90% of patients who underwent Enterprise-assisted coiling had a modified Rankin Scale score of 2 or less at last follow-up. A second microcatheter is inserted into the aneurysm sac, and the first Enterprise stent is deployed, bridg-ing the aneurysm neck. Case Study Brain & Spinal Cord Stent Assisted Coiling Case Study Details Aneurysm coiling gave a new lease of life to Mrs. Early cessation of antiplatelet agents may be associated with an increased risk of cerebral ischemic events. Background and Purpose— Stent-assisted coiling has expanded the treatment of intracranial aneurysms, but the rates of procedure-related neurological complications and the incidence of angiographic aneurysm recurrence of this novel treatment are not yet well known. Endovascular coiling is a procedure performed to block blood flow into an aneurysm (a weakened area in the wall of an artery). The present retrospective study assessed nine patients with ruptured very small intracranial aneurysms that underwent Solitaire AB stent-assisted coiling embolization between July 2010 and December 2012.

Original Article Stent-assisted coil embolization of intracranial aneurysms: A single center experience Chao-Bao Luo a,b,c,*, Michael Mu-Huo Teng a,b, Feng-Chi Chang a,b, Chung-Jung Lin a,b,. Endovascular treatment for unruptured aneurysm: stent-assisted coiling. Procedural complications occurred in 10. A series of connected spirals or concentric rings formed by gathering or winding: a coil of rope; long coils of hair. Follow-up 3-D angiography at 6 months revealed a patent renal artery with continued exclusion of the aneurysm and preservation of renal blood flow. Stent-assisted coiling remains a widely popular option for the treatment of aneurysm, according to a recent survey of 211 neurointerventionalists. The literature studies reported values of rates of thromboembolic complications related to stent-assisted coiling technique ranging from 4. PATIENTS AND METHODS: 57 patients with MCA trifurcation wide-necked aneurysms un-derwent stent-assisted coiling embolization using a solitaire AB stent. This study demonstrated that noncovered stent-assisted coil embolization is safe and effective in patients with wide-based RAAs. This study reports the first clinical experience with AS. This is passed into the diseased part of the artery using a balloon. The recommendations are intended to promote the safe and. Stent-assisted coil embolization can preserve parent vessel flow and obliterate the aneurysm. Clinical and angiographic results were analyzed. The rates of favorable outcomes (82. Stent assisted coiling rajesh kumar. Because of low risk of rupture in such aneurysms, the coiling of unruptured such aneurysms must be selective. Flow Diversion. 3%) underwent retreatment of their aneurysms during the follow-up period. Complications of conventional coiling include coil protrusion or luxation from the aneurysm into the parent vessel, which are related to aneurysm geometry and configuration. 5 -4 mm, while ST stents were recommended for aneurysms arising from a parent vessel with a diameter of 2. The combination of aspirin and clopidogrel is generally used to decrease these complications, but some patients do not respond to clopidogrel and have a higher risk of stent thrombosis. Materials and methods The analysis included 34 consecutive ruptured and unruptured wide-neck aneurysms. Brain Stents 2 Introduction Brain stents are devices implanted in the brains of people with high risk conditions of the brain arteries. Because clopidogrel is a prodrug treatment should be initiated 5-6 days before efficacy assessment. When the neck of the aneurysm is too wide, a stent is sometimes necessary to be placed in the parent vessel to hold the coils inside the body of the aneurysm. The rate of ischemic events was 1 (14. Methods: Patients underwent Neuroform stent-assisted coil embolization were registered in a database. Methods All intracranial aneurysms treated by stent-assisted coiling using a single AS in a single institution were retrospectively evaluated. Lawson and Oliver perform traditional coiling as well as advanced stent-assisted coiling, balloon-assisted coiling, and embolization using flow diversion devices. Flow chart of our antiplatelet therapy assessment prior to elective stent-assisted coiling procedures. Higher complication rates are associated with coiling before stenting, use of multiple stents, and hypertension. Intravascular or neck bridging device. EP stents were used for aneu - rysms arising from a parent vessel with a diameter of 2. This technique has been described for basilar tip aneurysms and middle cerebral artery bifurcation aneurysms using Neuroform and Enterprise stents.
