Intracerebral hemorrhage in young people: analysis of risk factors, location, causes, and prognosis

BACKGROUND AND PURPOSE: The frequency of intracerebral hemorrhages (ICHs) in people aged 31 years (odds ratio, 3.48), and those with ICH that resulted from arteriovenous malformations were aged <20 years (odds ratio, 2.80). The final outcome was considered favorable in 60%. CONCLUSIONS: ICHs in young people are mainly lobar in location and result from vascular malformation. Hypertension causes most cases in which the ICH is located in the basal ganglia. Mortality and morbidity in the acute phase are low and are related to hypertension as the cause of ICH.     

Spontaneous intracerebral hemorrhages in young patients. Study of 33 cases]

We report 33 cases of intracerebral hemorrhage (ICH) in patients aged from to 9/44 years (male: 20, female: 13, mean age: 32.5 years). ICH was due to vascular malformations in 39 p. 100 of cases, to arterial hypertension in 30% and to various causes in 18% no cause could be found in 13% of the cases. ICH was lobar in 64%, deep in 33% and infratentorial in 3% of the cases. The diagnosis was assessed by arteriography in 9 patients. The vascular malformations were arterial angiomas, saccular aneurysms and cavernous angiomas. Death rate was 24%. There was a fast ICH handicap in 40% of cases. Only 36% of the patients were not disabled.     

Nontraumatic intracerebral hemorrhage in young adults

We reviewed our experience with 72 patients, aged 15 to 45 years, who were hospitalized for nontraumatic intracerebral hemorrhages (ICHs) between 1978 and 1985. Evaluation included arteriography in 61 patients. Computed tomography demonstrated 41 lobar, 11 putaminal, four thalamic, four pontine, four intraventricular, two caudate, two midbrain, two cerebellar, one globus pallidum, and one corpus callosum hemorrhage. Forty-three patients, with either progressive neurologic deterioration, arteriovenous malformations (AVMs), or saccular aneurysms underwent surgery. The overall in-hospital survival, including those patients treated medically, was 87.5%. A presumed cause for the ICH was found in 55 (76.4%) patients. The main causes were ruptured arteriovenous malformations (21), hypertension (11), ruptured saccular aneurysms (seven), and sympathomimetic drug abuse (five). Surgical explorations demonstrated a necrotizing angiitis in one patient and arteriovenous malformations in two patients who had negative arteriograms. Young patients with nontraumatic ICHs represent a heterogeneous group. A cause can be established in most patients. Arteriovenous malformations account for less than one third of the hemorrhages in young adults, and other causes should be sought.     

Intracerebral hemorrhage in COVID-19: A narrative review

Coronavirus Disease 19 (COVID-19) pandemic affects the worldwide healthcare system and our understanding of this disease grows rapidly. Although COVID-19 is a mainly respiratory disease, neurological manifestations are not uncommon. The aim of this review is to report on the etiology, clinical profile, location, and outcome of patients with intracerebral hemorrhage (ICH) and COVID-19. This review includes 36 studies examining ICH in the clinical presentation of COVID-19. Overall, 217 cases with intracranial hemorrhage, of which 188 ICHs, were reported. Generally, a low incidence of both primary and secondary ICH was found in 8 studies [106 (0.25%) out of 43,137 hospitalized patients with COVID-19]. Available data showed a median age of 58 years (range: 52–68) and male sex 64%, regarding 36 and 102 patients respectively. Furthermore, 75% of the patients were on prior anticoagulation treatment, 52% had a history of arterial hypertension, and 61% were admitted in intensive care unit. Location of ICH in deep structures/basal ganglia was ascertained in only 7 cases making arterial hypertension an improbable etiopathogenetic mechanism. Mortality was calculated at 52.7%. Disease related pathophysiologic mechanisms support the hypothesis that SARS-CoV2 can cause ICH, however typical ICH risk factors such as anticoagulation treatment, or admission to ICU should also be considered as probable causes. Physicians should strongly suspect the possibility of ICH in individuals with severe COVID-19 admitted to ICU and treated with anticoagulants. It is not clear whether ICH is related directly to COVID-19 or reflects expected comorbidity and/or complications observed in severely ill patients.     

Cerebrovascular disease in the elderly--a clinicopathological study of 73 autopsied cases with intracerebral hemorrhage

The medical records and autopsy data of patients over the age of 70 years at death with a diagnosis of intracerebral hemorrhage (ICH) in the Yokufukai Geriatric Hospital were reviewed. All cases with ICH caused by head injury, rupture aneurysms or arteriovenous malformations were excluded from this study. There were 73 autopsied cases with spontaneous ICH from January 1978 to September 1988. There were 33 men and 40 women. Fourteen percent of the patients had a stroke while hospitalized for another disorder. Their ages at death ranged from 70 to 99 years with a mean of 81.8 years. Of these, 48 cases (66%) were 70 years or older at the time of ICH. In the senile ICH (over 70 years), the following characteristics were observed; (1) the most common location was the thalamus, which accounted for 33.3% of the hemorrhage. (2) subcortical and cerebellar hemorrhage accounted for 16.6% and 14.6% of the total, respectively. (3) there was no pontine hemorrhage. Fifty-seven percent had anamnestic hypertension before the stroke. The ages at which they became bedridden state ranged from 62 to 92 years with a mean of 79.5 years. This study revealed that the non-organic factors such as insidious generalized muscular weakness or decreased spontaneity were important as causes of the deterioration of ADL in the chronic stage of the senile ICH. Within one year after becoming bedridden state, 76.1% of all patients died. The bedridden state in the elderly with the residuals of ICH indicated a poor prognosis. As causes of death, pneumonia occurred in 28.8% of all patients, brain death in 19.2%, and sudden death in 12.3%.     

Risk of recurrent intracerebral hemorrhages

Abstract

Intracerebral hemorrhage (ICH) occurs in about 10%-15% of all strokes, and hypertension and cerebral amyloid angiopathy (CAA) are the main underlying causes. There is often controversy regarding surgical evacuation especially in elderly patients. Follow-up of these patients and regulation of hypertension is important to prevent re-bleeding. The number of recurrent hematomas will increase with time of follow-up. We reviewed 968 patients with an ICH treated in our Department and 48 patients with recurrent hemorrhages (4.9%). The mean interval between the first and the second hemorrhage was three years (one month to 10 years). Clinical outcome after a second hemorrhage was severe and only 50% of patients were operated on the second hemorrhage compared to 77% (37/48) of patients who were operated on the first hemorrhage.     

Spontaneous intracranial hematomas: role of dynamic CT and angiography

Forty-five patients with spontaneous intracerebral hemorrhage (ICH) were studied prospectively by dynamic CT and cerebral angiography. The accuracy of dynamic CT in demonstrating the underlying vascular cause in ICH was evaluated. Dynamic CT correctly predicted 90% of aneurysms, 83% of AVMs and 100% of normal studies as compared to angiography. Cerebral angiography can be obviated in patients where dynamic CT does not show any obvious vascular anomaly.     

A prospective epidemiological and aetiological study of strokes in young Afro-Caribbean patients from Martinique, French West Indies

Few data are available regarding stroke among young black patients. We have conducted, in Martinique, a prospective study among young Afro-Caribbeans aged 15 to 45 Years, from June 1994 through May 1999. We identified 60 cerebral infarcts (CI) and 20 cases of intracerebral hemorrhage (ICH). Annual incidence and case fatality rate at 30 days were 7.6/100000/Year (95p.cent confidence interval, 3.13 to 11.35) and 8.3p.cent respectively for CI, and 2.42/100000/Year (95p.cent confidence interval, 0.06 to 4.7) and 25p.cent for ICH. Hypertension was the most prevalent stroke risk factor: 35p.cent in CI and 68p.cent in ICH. According to the TOAST criteria, a probable cause of ischemic stroke was identified in 61.3p.cent. Atherosclerosis, lacunar infarcts and cardioembolism were the main causes of CI (13.3p.cent for each etiology). Spontaneous cervical arterial dissection was found in only 6.7p.cent. Hypertensive ICH (60p.cent) was the most common subtype of ICH. In Martinique, high frequencies of ICH and lacunar infarcts are characteristic of stroke in young Afro-Carribeans. These suggest the role of the high prevalence of hypertension in the black population. We confirm the heterogeneity of stroke etiologies and the low prevalence of cervical arterial dissection in black people.     

Hypertension is a Leading Cause of Nontraumatic Intracerebral Hemorrhage in Young Adults

Objective: To evaluate the etiology and discharge outcome of nontraumatic intracerebral hemorrhage (ICH) in young adults admitted to a comprehensive stroke center. Methods: A retrospective chart review was performed on patients with a discharge diagnosis of nontraumatic ICH admitted from 7/1/2011 to 6/30/2016. Data was collected on demographics, clinical history, ICH score, hemorrhage location, do-not-resuscitate (DNR) orders, likely etiology, and discharge disposition. Categorical data was reported as percentage. Chi-squared test was performed to evaluate association of location of ICH, etiology of ICH, and ICH score with the discharge outcome. Results: Sixty-three patients met the study criteria, with mean age 35.4 ± 6.4 years including 26 (41%) women and 40 (64%) whites. Headache (65%) and change in mental status (48%) were the most common presenting symptoms. Hemorrhage was most commonly seen in the deep structures in 29 (46%) patients followed by lobar ICH in 14 (22%) patients. The most common etiology of ICH was hypertension in 23 (37%) patients, followed by vascular abnormalities in 18 (29%) patients. Forty-two (67%) had good outcome defined as discharge to home (n = 25) or acute inpatient rehabilitation (n = 17). Twenty-one (33%) patients had bad outcome with discharge to skilled nursing facility (n = 6), hospice (n = 1) or died in the hospital (n = 14). Hospital DNR orders were noted in 11 (18%) patients. Higher ICH score (P < .0001) and use of DNR orders (P < .0001) were associated with bad outcome. All 11 patients with DNR orders died in the hospital. Location or etiology of hemorrhage were not associated with discharge outcome. Conclusions: Hypertension, a modifiable risk factor, is a major cause of nontraumatic ICH in young adults. Aggressive management of hypertension is essential to halt the recent increased trends of ICH due to hypertension. Early DNR orders may need to be cautiously used in the hospital.

Stroke in Saudi Arabian young adults: a study of 120 cases

One hundred and twenty cases of stroke occurring in Saudi Arabian subjects aged 15 to 45 years are reviewed. These constituted 12.7% of a group of 946 stroke patients. Males outnumbered females (76/44). The frequency of intracranial hemorrhage, including subarachnoid hemorrhage, was slightly lower than cerebral infarction (41.5 vs 58.5%). The causes of large cerebral infarction were as follows: atherosclerosis 17 (28%), cardiac embolism 12 (19.5%), uncommon and uncertain causes 21 (34.5%). Some unusual causes were encountered such as dissecting arterial aneurysm due to popular healing manoeuvres or to traditional dance, retrograde embolism from a thoracic outlet syndrome or embolism from a fibroelastoma of the mitral valve chorda. Lacunar cerebral infarction was diagnosed in nine cases. Hypertension (25.5%) and arteriovenous malformations (20.5%) were the main causes of cerebral hemorrhage; all subarachnoid hemorrhages except one were due to berry aneurysms. The cause was undetermined in 16% of cerebral infarction and 26% of intracranial hemorrhage. The high frequency of stroke in young Saudi Arabian adults is probably a reflection of the demographic structure of the predominantly young Saudi society. The observed causes were relatively similar to those in industrial societies. Contrary to other developing countries infectious disease no longer seems to be an important cause of stroke. Drug abuse, which is becoming an important cause in Western societies, was encountered in only two of our cases.     

Leukoaraiosis is associated with warfarin-related hemorrhage following ischemic stroke

BACKGROUND AND OBJECTIVES: Prior ischemic stroke is a risk factor for intracerebral hemorrhage (ICH) in patients taking warfarin, but the mechanism is not known. This study investigates radiographic and clinical characteristics of patients with warfarin-related ICH following ischemic stroke. METHODS: In this case-control study, the authors selected all patients with warfarin-related ICH and previous symptomatic ischemic stroke from a prospective cohort of consecutive patients with ICH. Control subjects were similarly aged patients with history of symptomatic stroke randomly chosen from an anticoagulant therapy unit. The 26 eligible ICH cases and 56 controls were compared for vascular risk factors, stroke characteristics, and extent of leukoaraiosis (graded in anterior and posterior brain regions on a validated scale of 0 to 4). RESULTS: The presence and severity of leukoaraiosis on CT scan correlated strongly with the occurrence of ICH. Leukoaraiosis was seen in 24 of 26 cases (92%) compared with 27 of 56 controls (48%), yielding an odds ratio of 12.9 (95% CI 2.8 to 59.8). Other clinical factors associated with ICH included an international normalized ratio >3.0, history of multiple previous strokes, and the presence of carotid artery stenosis. The relationship between leukoaraiosis and ICH persisted in multivariable analyses controlling for these risk factors as well as hypertension and diabetes mellitus. CONCLUSIONS: Leukoaraiosis is an independent risk factor for warfarin-related ICH in survivors of ischemic stroke, including those in the commonly employed range of anticoagulation.     

Potential triggering factors of intracerebral hemorrhage

The distributions of intracerebral hemorrhage (ICH) according to place of onset, degree of physical activity at onset and potential triggering factors were analyzed in 848 patients with ICH. Patients were grouped according to the presumed cause of ICH: hypertensive ICH, secondary ICH and ICH of undetermined origin. The influence of demographic and temporal factors on the relative frequency of events was also assessed. In 30% of the cases, ICH occurred during inactivity or sedentary activity, in 50% during light exertion and in 20% during moderate/vigorous exertion. During inactivity or sedentary activity, hypertensive ICH was significantly less frequent than secondary ICH (OR 0.32; 95% CI 0.21-0.47) and undetermined ICH (OR 0.36; 95% CI 0.23-0.55), whereas during moderate or vigorous exertion hypertensive ICH was more frequent than secondary (OR 1.88; 95% CI 1.16-3.05) and undetermined ICH (OR 2.29; 95% CI 1.31-4.00) Potential triggering factors were observed in 27% of patients and were significantly more frequent in patients with hypertensive ICH than in patients with secondary ICH (OR 2.90; 95% CI 1.85-4.54) or undetermined ICH (OR 2.44; 95% CI 1.54-3.87). Our findings suggest that many potential external triggers that act mainly by raising blood pressure may interact, and their concurrence may favor cerebral hemorrhage, particularly in hypertensive patients. In many cases, these circumstances of increased risk may be mitigated by preventive measures.     

The effects of selective brain hypothermia on intracerebral hemorrhage in rats

Prolonged hypothermia effectively treats global cerebral ischemic injury in animal models as well as in cardiac arrest victims. Furthermore, clinical trials, based upon encouraging animal findings, are underway to assess efficacy in ischemic stroke. Intracerebral hemorrhage (ICH) is a more devastating stroke, but one that shares mechanisms of injury with ischemia. Accordingly, ICH may be amenable to hypothermia treatment. In this study we tested whether selective brain hypothermia improves outcome after an ICH in rats created by infusing 100 microL of autologous whole blood into the striatum. Striatal hypothermia ( approximately 32 degrees C) was induced with a novel method (implanted cooling coil) that does not cause systemic cooling, thereby providing a safer and potentially more effective treatment for stroke than systemic hypothermia. Edema occurred for 4 days after ICH, but it peaked at 3 days ( approximately 5%). At this time it was significantly reduced (to approximately 2%) by cooling starting 1 h after ICH (3 day duration). Next, we determined whether 1 and 12 h delayed cooling treatments (4 day duration) would lessen functional impairment and lesion size. Untreated (normothermic) ICH resulted in significant forelimb use asymmetry, as well as deficits in walking and skilled reaching. These deficits were unaffected by hypothermia, as was the volume of tissue lost ( approximately 20 mm(3)) at 1 month. Thus, attenuated edema did not result in behavioral or histological benefit. In conclusion, while additional research with alternative cooling protocols and ICH models are required, these findings suggest that while hypothermia lessens edema, it will not be directly neuroprotective after ICH.     

Cerebrovascular disorders in young adults in Saudi Arabia. A study of 136 cases]

We report our experience of stroke in 136 young adults aged from 18 to 45 years seen in the Eastern Province of Saudi Arabia over a 10-year period. They constituted 25% of all our stroke cases. Thirty-eight percent were Saudi nationals and 62% expatriates. Males largely outnumbered females. The frequency of cerebral infarction (54%) was not very different from that of intracranial hemorrhage (45%). Atherosclerosis and embolism of cardiac origin were the major causes of infarction. The main causes of intracranial bleeding were arterial aneurysms, arteriovenous malformations and hypertension. However, the causes of 29% of ischemic strokes and 44% of hemorrhagic ones remained undetermined. Interethnic comparison of the causes showed that hemorrhages were significantly more frequent in Far East immigrants. Sixty five percent of cerebral infarctions in Asiatic patients remained of undetermined origin. The local variant of sickle cell gene did not seem to play a major role in the pathogenesis of stroke in the Saudi young adult. These data are commented and compared with similar reported data. The influence of the demographic structures of the Saudi population and immigrants communities is analyzed.     

Aspects of intracerebral hematomas--an update

Background – In Norway, there are approximately 16000 strokes each year and 15% of these are caused by intracerebral hematomas. Intracerebral hemorrhage (ICH) results from the rupture of blood vessels within the brain parenchyma. ICH occurs as a complication of several diseases, the most prevalent of which is chronic hypertension. When hemorrhage develops in the absence of a pre‐existing vascular malformation or brain parenchymal lesion, it is denoted primary ICH. Secondary ICH refers to hemorrhage complicating a pre‐existing lesion. Primary ICH is the most common type of hemorrhagic stroke, accounting for approximately 10% of all strokes. Despite aggressive management strategies, the 30‐day mortality remains high, at almost 50%, with the majority of deaths occurring within the first 2 days. At 6 months, only 20–30% achieve independent status. Material and methods – This article is based on clinical experience, modern therapeutic guidelines for the treatment of intracerebral hematomas and up‐to‐date medical literature found in Medline. The article discusses the pathophysiology, clinical aspects, treatment, and the prognosis of intracerebral hematomas. Results and discussion – Advances in diagnosis, prognosis, pathophysiology, and treatment over the past few decades have significantly advanced our knowledge of ICH; however, much work still needs to be carried out. Future genetic and epidemiologic studies will help identify at‐risk populations and hopefully allow for primary prevention. Randomized controlled studies focusing on novel therapeutics should help to minimize secondary injury and hopefully improve morbidity and mortality.     

Cerebrovascular disease in the elderly--clinical study of 31 cases with acute intracerebral hemorrhages

Thirty-one consecutive cases of intracerebral hemorrhage (ICH) in the elderly (over 70 years at the onset) were reported with special reference to neurological evaluations, prognosis and mortality in the acute phase. There were 11 men and 20 women with ICH, who were admitted to the Yokufukai Geriatric Hospital within 24 hours after the onset of ICH. Their ages at the onset ranged from 71 to 93 years with a mean of 81.1 years. The lesion location showed 5 cases with thalamic hemorrhage, 4 cases with putaminal hemorrhage, 6 cases with subcortical hemorrhage, 7 cases with cerebellar hemorrhage, 8 cases with mixed hemorrhage and 1 case with unclassified hemorrhage. 61.3% of all cases showed the onset during daytime but the remaining awoke in the morning with their symptoms or had the onset from the stage of the bedridden state. The classical prodromal symptoms headache and nausea or vomiting were found in 30% and 54.8%, respectively. Two cases with cerebellar hemorrhage were accompanied by vertigo. Twenty-four patients had consciousness disturbance at admission. There were 18 cases with right or left hemiparetic symptoms, 5 cases with tetraparesis, and 5 cases without motor dysfunction. The remaining already had hemiparesis due to old stroke. Patients with mixed hemorrhage usually exhibited conjugate deviation. In 9 of 31 cases there were mental symptoms such as wandering or night delirium. The 30-day mortality rate was 64.5% and sixty-five percent of them died within 6 days after the onset of ICH. Consciousness at admission was the overwhelming predictive factor.(ABSTRACT TRUNCATED AT 250 WORDS)
