We report the case of long-term follow-up of brain magnetic imaging of cerebral amyloid angiopathy. Cerebral amyloid angiopathy is often considered a major cause of spontaneous intracerebral hemorrhage in the elderly. This case illustrates the markedly progressive clinical and radiological features of the vasculopathic process in 10 years.

Abstract Background The modified Boston criteria (mBC) define the probability for the diagnosis of cerebral amyloid angiopathy (CAA). Its initial clinical presentation differs from asymptomatic cerebral microbleedings (cMBs), acute ischemic stroke (AIS), cortical hemosiderosis (cSS), to lobar ICH (lICH). Methods Retrospective analyses and clinical follow-ups of individuals with at least mBC “possible” CAA from 2005 to 2018. Results 149 patients were classified in subgroups due to the index event: lICH (n = 91), AIS (n = 32), > 3 cMBs only (n = 16) and cSS (n = 10). Patients in the lICH subgroup had a significantly higher percentage of single new lICHs compared to other groups, whereas patients in the AIS-group had a significantly higher percentage of multiple new AIS. cMBs as index event predisposed for AIS during follow up (p < 0.0016). Patients of the cMBs- or cSS-group showed significantly more TFNEs (transient focal-neurological episodes) and lower numbers of asymptomatic patients (for epilepsy and TFNEs) at the index event than patients with lICH or AIS (p < 0.0013). At long-term follow-up, the cMBs- and cSS-group were characterized by more TFNEs and fewer asymptomatic patients. Conclusions A new classification system of CAA should add subgroups according to the initial clinical presentation to the mBCs allowing individual prognosis, acute treatment and secondary prophylaxis.

Long Term Mortality

Background: A post-hoc analysis of the PROGRESS trial suggested that long-term anti-hypertensive therapy prevents intracerebral hemorrhage (ICH) in patients with cerebral amyloid angiopathy (CAA). However, the burden of underlying hypertension in patients with CAA is unclear, and it is also unclear whether this hypertensive burden contributes to long-term outcome in survivors of CAA-related ICH. Left ventricle (LV) hypertrophy is a measure of the chronicity and severity of hypertension and could be used to assess hypertensive end-organ damage in patients with CAA. Objective: To test the hypothesis that LV hypertrophy is common in patients with CAA-related ICH and is associated with increased long-term mortality and shorter survival in those patients. Methods: This was a retrospective analysis of a prospectively collected cohort of consecutive patients with primary ICH presenting to a single academic center. We included patients presenting between January/2000 to December/2010, age > 55 years, who received a transthoracic echocardiogram (echo) during follow-up and were diagnosed with definitive, probable or possible CAA according to the Boston criteria. LV mass index (10g/m2) was calculated according to Penn convention. Ninety-day survivors were followed prospectively for long-term mortality or censoring at January/2012. Cox proportional hazards models were used to identify predictors of mortality as time-dependent variables adjusting for potential confounders. Results: Among 211 patients who met inclusion criteria, the mean time to follow-up was 4.28 ± 2.7 years; the median time to echocardiogram was 3 days (IQR:49). The mean age was 75.7 ± 9.1 years; 103 (49%) were male. LV hypertrophy was present in 55 (31.8%) patients and 152 (72%) patients survived more than 90 days. In multivariate analysis, after adjusting for baseline characteristics, LV mass index (10g/m2) was associated with higher long-term mortality (HR: 1.20; 95%CI: 1.01-1.4; p=0.039). On Cox-regression, LV hypertrophy was independently associated with shorter long-term survival (HR 1.91; 95%CI 1.05-3.47; p=0.034). Conclusions: LV hypertrophy is common in patients with CAA-related ICH and is associated with increased risk of subsequent mortality among 90-day survivors.

Absorbable Tacks

Background: Laparoscopic Incisional and Ventral Hernia Repair (LIVHR) is a safe and worldwide accepted procedure performed using absorbable tacks. The aim of the study was to evaluate recurrence rate in a long term follow-up and whether the results of laparoscopic IVH repair in the elderly (≥65 years old) are different with respect to results obtained in younger patients. Methods: One hundred and twenty-nine consecutive patients (74 women and 55 men, median age 67 years, range = 30-87 years) with ventral (N = 42, 32.5%) or post incisional (N = 87, 67.5%) hernia were enrolled in the study. Patients were divided into two groups according to their age: group A (N = 55, 42.6%) aged <65 years and group B (N = 74, 57.4%) aged ≥65 years. Results: The mean operative time was not significantly different between groups (66.7 ± 37 vs. 74 ± 48.4 min, p = 0.4). To the end of 2016, seven recurrences had occurred (group A = 3, group B = 4, p = 1). Complications occurred in 8 (16%) patients in group A and 21 (28.3%) patients in group B. Conclusion: In conclusion, our results confirm that the use of absorbable tacks does not increase recurrence frequency and laparoscopic incisional and ventral repair is a safety procedure also in elderly patients.

Background: Mild cognitive impairment (MCI) is considered by some to be a prodromal phase of a progressive disease (i.e., neurodegeneration) resulting in dementia; however, a substantial portion of individuals (ranging from 5–30%) remain cognitively stable over the long term (sMCI). The etiology of sMCI is unclear but may be linked to cerebrovascular disease (CVD), as evidence from longitudinal studies suggest a significant proportion of individuals with vasculopathy remain stable over time. Objective: To quantify the presence of neurodegenerative and vascular pathologies in individuals with long-term (>5-year) sMCI, in a preliminary test of the hypothesis that CVD may be a contributor to non-degenerative cognitive impairment. We expect frequent vasculopathy at autopsy in sMCI relative to neurodegenerative disease, and relative to individuals who convert to dementia. Methods: In this retrospective study, using data from the National Alzheimer’s Coordinating Center, individuals with sMCI (n = 28) were compared to those with MCI who declined over a 5 to 9-year period (dMCI; n = 139) on measures of neurodegenerative pathology (i.e., Aβ plaques, neurofibrillary tangles, TDP-43, and cerebral amyloid angiopathy) and CVD (infarcts, lacunes, microinfarcts, hemorrhages, and microbleeds). Results: Alzheimer’s disease pathology (Aβ plaques, neurofibrillary tangles, and cerebral amyloid angiopathy) was significantly higher in the dMCI group than the sMCI group. Microinfarcts were the only vasculopathy associated with group membership; these were more frequent in sMCI. Conclusion: The most frequent neuropathology in this sample of long-term sMCI was microinfarcts, tentatively suggesting that silent small vessel disease may characterize non-worsening cognitive impairment.

Aneurysm Occlusion

Background Flow diversion with the Pipeline embolization device (PED) is a widely accepted treatment modality for aneurysm occlusion. Previous reports have shown no recanalization of aneurysms on long-term follow-up once total occlusion has been achieved. Case description We report on a 63-year-old male who had a large internal carotid artery cavernous segment aneurysm. Treatment with PED resulted in complete occlusion of the aneurysm. However, follow-up angiography at four years revealed recurrence of the aneurysm due to disconnection of the two PEDs placed in telescoping fashion. Conclusion Herein, we present the clinico-radiological features and discuss the possible mechanisms resulting in the recanalization of aneurysms treated with flow diversion.

ObjectiveTo assess the association of cortical superficial siderosis (cSS) presence and extent with future bleeding risk in cerebral amyloid angiopathy (CAA).MethodsThis was a meta-analysis of clinical cohorts of symptomatic patients with CAA who had T2*-MRI at baseline and clinical follow-up for future intracerebral hemorrhage (ICH). We pooled data in a 2-stage meta-analysis using random effects models. Covariate-adjusted hazard ratios (adjHR) from multivariable Cox proportional hazard models were used.ResultsWe included data from 6 eligible studies (n = 1,239). cSS pooled prevalence was 34% (95% confidence interval [CI] 26%–41%; I2 87.94%; p < 0.001): focal cSS prevalence was 14% (95% CI 12%–16%; I2 6.75%; p = 0.37), and disseminated cSS prevalence was 20% (95% CI 13%–26%; I2 90.39%; p < 0.001). During a mean follow-up of 3.1 years (range 1–4 years), 162/1,239 patients experienced a symptomatic ICH-pooled incidence rate 6.9% per year (95% CI 3.9%–9.8% per year; I2 83%; p < 0.001). ICH incidence rates per year according to cSS status were 3.9% (95% CI 1.7%–6.1%; I2 70%; p = 0.018) for patients without cSS, 11.1% (95% CI 7%–15.2%; I2 56.8%; p = 0.074) for cSS presence, 9.1% (95% CI 5.5%–12.8%; I2 0%; p = 0.994) for focal cSS, and 12.5% (95% CI 5.3%–19.7%; I2 73.2%; p = 0.011) for disseminated cSS. In adjusted pooled analysis, any cSS presence was independently associated with increased future ICH risk (adjHR 2.14; 95% CI 1.19–3.85; p < 0.0001). Focal cSS was linked with ICH risk (adjHR 2.11; 95% CI 1.31–2.41; p = 0.002), while disseminated cSS conferred the strongest bleeding risk (adjHR 4.28; 95% CI 2.91–6.30; p < 0.0001).ConclusionIn patients with CAA, cSS presence and extent are the most important MRI prognostic risk factors for future ICH, likely useful in treatment planning.Classification of evidenceThis study provides Class III evidence that in symptomatic CAA survivors with baseline T2*-MRI, cSS (particularly if disseminated, i.e., affecting >3 sulci) increases the risk of future ICH.

Objective:In order to explore the mechanisms of cortical superficial siderosis (cSS) multifocality and its clinical implications for recurrent intracerebral hemorrhage (ICH) risk in patients with cerebral amyloid angiopathy (CAA), we used a new rating method that we developed specifically to evaluate cSS extent at spatially separated foci.Methods:Consecutive patients with CAA-related ICH according to Boston criteria from a single-center prospective cohort were analyzed. The new score that assesses cSS multifocality (total range 0–4) showed excellent interrater reliability (k = 0.87). The association of cSS with markers of CAA and acute ICH was investigated. Patients were followed prospectively for recurrent symptomatic ICH.Results:The cohort included 313 patients with CAA. Multifocal cSS prevalence was 21.1%. APOE ε2 allele prevalence was higher in patients with multifocal cSS. In probable/definite CAA, cSS multifocality was independently associated with neuroimaging markers of CAA severity, including lobar microbleeds, but not with acute ICH features, which conversely, were determinants of cSS in possible CAA. During a median follow-up of 2.6 years (interquartile range 0.9–5.1 years), the annual ICH recurrence rates per cSS scores (0–4) were 5%, 6.5%, 13.5%, 16.2%, and 26.9%, respectively. cSS multifocality (presence and spread) was the only independent predictor of increased symptomatic ICH risk (hazard ratio 3.19; 95% confidence interval 1.77–5.75; p < 0.0001).Conclusions:The multifocality of cSS correlates with disease severity in probable CAA; therefore cSS is likely to be caused by discrete hemorrhagic foci. The new cSS scoring system might be valuable for clinicians in determining annual risk of ICH recurrence.
