The residual filling, if seen, was seen in the center of the 2-mm coil loop. However, polymer emboli may result from excessive or rapid glue injection.14 We prefer to perform coil embolization in small aneurysms. Work-up of SAH with CTA versus conventional angiography is a frequently debated topic and, as pointed out by Kallmes et al,8 CTA can result in false-negative results, and 3DRA probably remains the most accurate study in these patients. Depends on damage at bleeds. If untreated, another 50% will die within a month, with a 20% risk of rebleed by the end of the first two weeks. Once an aneurysm is found, it requires a careful evaluation by a specialist who understands the risk an aneurysm could pose to the patient. This may have biased the results in favor of a positive outcome because anatomic features such as atherosclerosis or extreme tortuosity were absent in the younger age group, favoring precise catheter manipulation. Medical studies show the risk of a brain aneurysm rupturing is quite low. Small size makes for challenging aneurysm catheterization, the risk for perforation by microcatheters that load and spring forward, and difficulty placing multiple coils.13 The small size of the aneurysm may be associated with a higher risk for rupture during embolization.2,3 Review of the English-language literature revealed only 1 study by Suzuki et al,4 who reported on endovascular treatment of very small aneurysms. E, Angiogram before coil detachment shows a well-placed coil with the microcatheter tip outside the aneurysm. Aneurysms can be fatal and, unfortunately, there are often no symptoms. can survivors of ruptured brain aneurysm live a normal life following medical treatment? DSA was performed followed by 3DRA. C, DSA in the same angulation as the 3D image. CT angiography (CTA) had been performed in 3 patients and detected the aneurysm in 2 of the patients. Therefore, it is important that decisions regarding optimum management are made based on the comparison of the risk of aneurysm… In such cases, wrapping of the artery with muscle, Surgicel (Ethicon, Somerville, NJ), or muslin gauze, coating of the aneurysm with vinyl polymers or cyanoacrylate adhesives, and direct coagulation of the aneurysm have been variably described as treatment options.10-12 In a similar fashion, very small aneurysm sizes may limit endovascular options. The smallest coil available during the period of study was 2-mm diameter, and the treatment dynamics change considerably in such cases compared with aneurysms larger than 2 mm. Another issue is retention of the coils in such small aneurysms. In 2 cases, minimal projection of the coil tip was seen into the parent artery before detachment and was considered to be acceptable. CTA and DSA may not detect some of these aneurysms. Previously presented as a short lecture at: Vascular Leaders Summit 2008 in Bangkok, Thailand, June 20–23, 2008. There are two main treatments for brain aneurysms. Follow-up DSA after 6 months revealed a completely thrombosed aneurysm with change in the configuration of the coil (Fig 3G). A single soft coil was used in all cases with the shortest available length. The technique also avoids the technical problems associated with other endovascular options. By using our website, you consent to our use of cookies. Goddard et al13 also reported on the use of a single coil in the treatment of small aneurysms with reasonable long-term stability in their series. E, Postembolization DSA. C, DSA in the same angulation as the 3D image shows a very small aneurysm (arrow) and its relationship with the anterior choroidal artery (arrowhead). Results on DSA performed at another institution were reported to be normal, and she was treated conservatively. Neurologist (MD) Doctoral Degree. Aneurysms can occur in any part of the body. The abdominal aortic aneurysm is dangerous if left untreated as it can lead to internal bleeding and can lead to stroke or death in severe cases. Ronnie Hall: I could have tipped over dead. After detachment, the tip of the coil prolapsed into the upper division of the MCA (Fig 4E). 3DRA and DSA are of higher resolution than CTA and are better in the detection of aneurysms and in defining the morphologic features of the aneurysm. Answer Save. If it … We considered that the coil projecting into the vessel would reconstruct the MCA bifurcation, and this was considered to be the “true neck” of the aneurysm. BACKGROUND AND PURPOSE: The very small size of cerebral aneurysms is considered to be one of the limitations for endovascular treatment, with a high risk for intraoperative rupture. Even if minimal contrast filling was seen, no additional coil placement was attempted. MATERIALS AND METHODS: We performed retrospective analysis of 7 consecutive cases of very small aneurysms treated by coil embolization in our institution between July 2006 and April 2008. An aneurysm is a bulge in a blood vessel caused by a weakness in the blood vessel wall, usually where it branches. what is the best treatment for a brain aneurysm? Careful consideration of the technical issues in treatment of these cases is essential to achieve technical success while avoiding complications.
