Frequency of intracranial hemorrhage as a presenting symptom and subtype analysis: a population-based study of intracranial vascular malformations in Olmsted County, Minnesota

Abstract: The purpose of this study was to determine the symptoms at presentation and the incidence of intracranial hemorrhage (ICrH) caused by intracranial vascular malformations (IVMs) in a defined population. The authors used the Mayo Clinic medical records linkage system to detect all cases of IVM among residents of Olmsted County, Minnesota, during the period 1965 through 1992. Forty-eight IVMs were detected over the 27-year period. Twenty-nine of the 48 patients were symptomatic at presentation. The most common pr… Show more

“…Estimates of the rate of cerebral AVM hemorrhage vary significantly depending on whether the analysis aims to report the cumulative or per annum risk [32][33][34][35], and the inclusion of recurrent and previous hemorrhages [7]. Given their relative rarity, confusion among classification systems [10], and the small number of modern clinical series with any natural history data, it is even more difficult to estimate the innate rate of bleeding for SCAVM.…”

“…It has been estimated that AVMs are found in approximately 0.1% of the US population and are responsible for approximately 2% of all hemorrhagic strokes. 2,5 AVMs have an annual risk of intracerebral hemorrhage that varies anywhere from 1% to 25%. 2,5,15 While cerebral AVMs are a relatively infrequent cause of stroke overall, they make up a particularly high percentage of hemorrhagic strokes in patients younger than 40 years.…”

“…7,19,22,25,30,34 According to reports, 0.1% of the population harbors an AVM, 3,8 and both sexes are equally affected. AVMs are the leading cause of nontraumatic intracerebral hemorrhage in people less than 35 years old.…”

“…37 Most lesions come to patients' attention in their 40s and 75% of the hemorrhagic presentations occur before the age of 50 years. 7 In addition, AVMs can cause debilitating headaches, seizures, and progressive neurological deficits due to ischemia of the surrounding abbreviatioNs AVM = arteriovenous malformation; DSA = digital subtraction angiography; GKS = Gamma Knife surgery; HR = hazard ratio; NBCA = N-butyl cyanoacrylate; RAS = Radiosurgery AVM Scale; RIC = radiation-induced change; SRS = stereotactic radiosurgery. obJective A combination of embolization and radiosurgery is used as a common strategy for the treatment of large and complex cerebral arteriovenous malformations (AVMs).…”
