guidelines for the management of patients with unruptured intracranial aneurysms

  • 09.01.2021

This statement is being published simultaneously in the November 2000 issue of Stroke. Among the patients with prior history of SAH with basilar tip UIAs of <10 mm, the rupture risk was ≈12% at 7.5 years compared with 3% for <10-mm UIAs in other locations. RESULTS: Evidence-based guidelines are presented for the care of patients presenting with unruptured intracranial aneurysms. In the meta-analysis by Raaymakers et al,62 aneurysm size correlated with morbidity and mortality rates, with smaller aneurysms associated with better rates.  |  The majority of studies of outcome after surgery for UIAs involve case series of one or more neurosurgeons in which their results are evaluated. Randomized trials with high likelihoods of false-negative and positive errors provide level II evidence. Studies have used the Glasgow Coma Scale score or modifications, but these scales are relatively insensitive to disabilities in good outcome strata. The guidelines are intended to serve as … To support the neurosurgery community in these unprecedented times, the CNS is offering complimentary online education. Coil embolization is a treatment option for UIAs. In addition, it should be recalled that in 2 studies in which UIAs later ruptured, the majority of UIAs showed enlargement, although the temporal course of this change remains undefined.1216 Finally, recommendations regarding the treatment of UIAs should be influenced by characteristics such as aneurysm morphology, extensive calcification, thrombosis, and more rarely encountered clinical features such as previous confirmation of the aneurysm and stability of size. Patients’ experiences, biases, and personal preferences influence the decision to treat and should also be considered.23. Purpose— The aim of this updated statement is to provide comprehensive and evidence-based recommendations for management of patients with unruptured intracranial aneurysms. 7272 Greenville Ave. Nonlethal complications in both settings can potentially improve over time. Although significant questions remain, ISUIA still represents the most comprehensive effort to date in documentation of the natural history of UIAs. However, the strength of the predictive value of size was marginal for the entire population (P=0.036) and was not statistically significant for the 131 patients with prior SAH. These syndromes support the theory of inherited susceptibility to aneurysm formation.8918252947, The familial intracranial aneurysm (FIA) syndrome occurs when 2 relatives, third degree or closer, have radiographically proved intracranial aneurysms.271114283048 Cohorts with this syndrome have SAH at a younger age than in the general aneurysm population, are more likely to harbor multiple aneurysms, and have more hemorrhages among siblings and mother-daughter pairings.21630 In family members with ≥2 first-degree relatives with SAH, the risk of harboring an unruptured aneurysm was found to be 8% in 1 study,32 whereas another study reported a relative risk of 4.2.45 Family members with only 1 affected first-degree relative have a higher relative risk of harboring an unruptured aneurysm than the general population but less than those with the FIA syndrome.4449 In patients who have been treated for a ruptured aneurysm, the annual rate of new aneurysm formation is 1% to 2%.17465051 Patients with multiple intracranial aneurysms may be particularly susceptible to new aneurysm formation.50, In evaluation of the clinical efficacy of screening for asymptomatic intracranial aneurysms, the costs of screening should be weighed against the risks and consequences of SAH. As found in the recent ISUIA, UIAs must be considered in the context of the patient’s previous history of aneurysmal SAH or lack thereof due to a difference in rupture rates in these 2 populations. © American Heart Association, Inc.

Recommendations for the management of patients with unruptured intracranial aneurysms: A statement for healthcare professionals from the Stroke Council of the American Heart Association. Noninvasive imaging techniques now exist, such as MRA and CT angiography, which are less expensive and noninvasive and have a high degree of sensitivity and specificity as outlined here. However, the group with late rebleeding included a significantly greater proportion with aneurysms ≥10 mm in diameter.17 In another study of 61 patients with SAH and 2 intracranial aneurysms in whom only the ruptured aneurysms had been clipped, 7 patients bled from a previously unruptured aneurysm, and 3 additional patients experienced fatal hemorrhage during a 10-year follow-up period. Symptoms due to UIAs should be discriminated relative to those developing rapidly and related to smaller aneurysms, presumably due to acute aneurysmal expansion. Population-based studies of SAH demonstrate a mortality rate for first SAH of 45%.1 However, the mortality rate after a first SAH in the ISUIA was 83%, and in a previous study by the same authors with similar patient selection criteria, the rate was >90%.4 This suggests that selection bias for inclusion in these studies resulted in the high mortality rates after rupture but could also be attributed to wide confidence intervals or a true higher mortality rate in this population. To date, there have been no randomized controlled clinical trials that addressed the cost effectiveness of screening for intracranial aneurysms, and only grade C recommendations can be made. Treatment complications generally occur at or around the time of the procedure but could potentially improve during the patient’s remaining lifetime. There are no prospective randomized trials of treatment interventions versus conservative management to date, and it is possible that no such studies will be carried out in the future. Evidence-based guidelines are presented for the care of patients presenting with unruptured intracranial aneurysms. Identification and validation of key genes mediating intracranial aneurysm rupture by weighted correlation network analysis.

Guidelines for the Management of Patients with Unruptured Intracranial Aneurysms. Recent studies have found that the following factors heavily influence the analysis of cost effectiveness for asymptomatic unruptured aneurysms: aneurysm incidence, risk of rupture (natural history), and risk of treatment.3245495253 Mathematical modeling studies have demonstrated that the cost effectiveness of screening is highly sensitive to the aneurysm rupture rate, even in populations at high risk for intracranial aneurysms. Guidelines for the Management of Patients with Unruptured Intracranial Aneurysms June 2015 Guideline from the American Heart Association/American Stroke Association. The majority of UIAs will never rupture. Several assumptions must be made to estimate these costs, such as how an aneurysm would be managed if detected, although this unrealistically simplifies the medical decision-making process. To date, >16 000 patients with ruptured and unruptured aneurysms have been treated worldwide with the GDC method.92 Published reports of early clinical and angiographic results suggest that this method is associated with fewer treatment-related complications than open surgery,9394 but the long-term efficacy of the GDC method in the prevention of rupture or growth of an unruptured aneurysm is, as yet, unproved. Rinkel GJE(1). The ISUIA findings differ from those of previous studies, which have shown (1) the mean diameter of aneurysms of patients who present with SAH to typically be <10 mm,19202122 (2) the surgical morbidity and mortality rates to be significantly lower (see later),2123 and (3) a considerably higher annual rupture rate than that reported by ISUIA.21 Like all natural history studies to date, ISUIA was based on retrospectively identified patients, which has raised controversy about patient selection. guideline is to present current and comprehensive recommendations for the management of intracranial aneurysms, with or without rupture. This important finding requires further investigation and must be considered in the assessment of individual patients for possible surgical treatment. 2011 Sep;42(9):2672-713. doi: 10.1161/STR.0b013e3182299496. Hemphill JC 3rd, Greenberg SM, Anderson CS, Becker K, Bendok BR, Cushman M, Fung GL, Goldstein JN, Macdonald RL, Mitchell PH, Scott PA, Selim MH, Woo D; American Heart Association Stroke Council; Council on Cardiovascular and Stroke Nursing; Council on Clinical Cardiology. The investigators used predefined criteria for patient entry and aneurysmal rupture across multiple centers, remeasurement of all aneurysms with hard-copy films that involved a defined system for magnification correction, and a published methodology for in-depth detection, review, and adjudication of detailed data regarding outcome events.8 This study also had sufficient numbers of patients to allow secondary subgroup analysis according to aneurysm size, location, and history of SAH from a different aneurysm. ISUIA constitutes the most comprehensive study on this issue, as previously outlined, and is the only study to systematically assess cognitive status before and after surgery across multiple centers with a team-evaluation approach.8 Although ISUIA enrolled surgeons from leading academic institutions, it did not specify outcome thresholds to credential surgeons before participation in the study. Three of 9 patients with 7- to 10-mm aneurysms bled; however, the precise sizes of these aneurysms were not stated.9 In a study from Japan, Inagawa et al10 studied 47 patients with 55 UIAs for a mean duration of 5.1 years. Nevertheless, as experience with microsurgical techniques increases, aneurysm location may become less of a factor that influences outcome, and recent studies report little or no increase in morbidity rates due to focal neurological deficits in cases of nongiant aneurysm of the posterior circulation.6669, Symptoms such as mass effect on cerebral or brain stem structures, compression of cranial nerves, or ischemic/embolic phenomena can be effectively treated with surgical clipping and decompression and can serve as an important indication for treatment.697677 For example, the development of a new third nerve palsy ipsilateral to an aneurysm of the posterior communicating artery implies growth of the aneurysm. If changes in aneurysmal size or configuration are observed, this should lead to special consideration for treatment. Methods— Writing group members used systematic literature reviews from January 1977 up to June 2014. As a general rule, exclusively extradural, intracavernous (internal carotid artery) aneurysms, even if symptomatic with pain or ophthalmoparesis, do not carry a major risk for intracranial hemorrhage, and thus management decisions are primarily aimed at symptom relief more than at hemorrhage prevention.8798, Among patient factors, patient age, general medical condition, and family history of aneurysmal SAH are prime considerations in the treatment analysis. These guidelines are intended to serve as a framework for the development of treatments for individuals and as a basis for future research regarding UIAs. Aneurysm location also predicted future rupture (posterior communicating, vertebrobasilar/posterior cerebral, and basilar tip UIAs were more likely to rupture). The guideline underwent extensive peer review, including review by the Stroke Council Leadership and Stroke Scientific Statement Oversight Committees, before consideration and approval by the American Heart Association Science Advisory and Coordinating Committee. They are usually discovered incidentally. There has been virtually no uniformity regarding the definition of good versus poor outcomes, or even mortality rates; some have been defined at 30 days, 3 to 6 months, or 1 year after surgery. Management of unruptured intracranial Aneurysms Abstract. Unruptured intracranial aneurysms (UIAs) are a common coincidental finding in cranial imaging of patients with non-correlated symptoms such as headache or dizziness. The average aneurysm size in those who bled was 13.1 mm. The aim of this updated statement is to provide comprehensive and evidence-based recommendations for management of patients with unruptured intracranial aneurysms. In a study by Wiebers et al14 that included 130 patients with a mean follow-up interval of 8.3 years, 15 of 130 patients had a subsequent intracranial hemorrhage. Aneurysms located at the basilar apex carry a relatively high risk of rupture. Surgical experience has been shown to influence outcome after intracranial aneurysm surgery. This review addresses the difficulties in managing incidental unruptured saccular intracranial aneurysms. However, alternative hypotheses could account for this observation, including a much higher prevalence of 7- to 10-mm aneurysms, a decrease in aneurysm size at the time of rupture, or a smaller critical size for aneurysms that rupture at the time they form or soon after they form. 2.7 %, although the mortality among patients with a follow-up of 3.5 years Heart Association formed task!
