BACKGROUND AND PURPOSE The morbidity from spontaneous hemorrhage of untreated brain arteriovenous malformations (AVM) is not well described. METHODS The 241 consecutive AVM patients (mean age 37+/-16 years, 52% women) from the prospective Columbia AVM Databank initially presenting with hemorrhage were evaluated using the Rankin Scale (RS) and the National Institute of Health Stroke Scale (NIH...

BACKGROUND AND PURPOSE To evaluate the hemorrhage rates of cerebral arteriovenous malformations (AVM) and the risk factors of hemorrhage before and after Gamma Knife radiosurgery (GKS). METHODS The annual hemorrhage rate was calculated as the number of hemorrhages divided by the patient-years at risk. Characteristics of patients and AVM related to hemorrhagic or nonhemorrhagic presentation we...

Abstract Introduction Many studies demonstrated that trauma-hemorrhage induces marked alterations in various immune functions. The trauma-hemorrhage-induced immunosuppression is associated with an increased susceptibility to subsequent sepsis, organ failure and mortality. Previous studies demonstrated that trauma-hemorrhage induces immunosuppression in both innate immune systems and adaptive im...

To emphasize the important association of polycystic kidney disease and hypertensive cerebral hemorrhage, a registry of 900 consecutive cases of hemorrhagic stroke was reviewed. Eleven patients (1.2%) had intracranial hemorrhage (eight had hypertensive cerebral hemorrhage and the other three had aneurysmal subarachnoid hemorrhage) found to be associated with polycystic kidney disease. These 11 ...

Automated hemorrhage detection and segmentation in traumatic pelvic injuries is vital for fast and accurate treatment decision making. Hemorrhage is the main cause of deaths in patients within first 24 hours after the injury. It is very time consuming for physicians to analyze all Computed Tomography (CT) images manually. As time is crucial in emergence medicine, analyzing medical images manual...

Intraplaque hemorrhage in atherosclerotic plaques has been associated with accelerated plaque growth as well as exacerbation of clinical symptoms. The identification of intraplaque hemorrhage using magnetic resonance imaging primarily relies on the detection of methemoglobin on T(1) weighted images. Current techniques are limited by insufficient intraplaque hemorrhage-wall contrast and poor blo...

Introduction:Intracranial hemorrhage (ICH) is divided into two traumatic and non-traumatic categories. The present study sought to investigate the anatomical properties of non-traumatic intracranial hemorrhage in Kerman, Iran. Method:A total of 305 non-traumatic ICH cases were chosen in Shafa medical center. Data from patients’ files and CT scan images, including demographic factors and type o...

Hemorrhage of the basal ganglia is common in hypertensive patients, and most of the cases are spon- taneous unilateral hemorrhage. Traumatic basal ganglia hemorrhage is uncommon, while bilateral hemorrhage of the basal ganglia after trauma is an extremely rare entity. This report described a rare case of bilateral hemorrhage of the basal ganglia after head trauma. We also analyzed the mechanism...

It is unclear whether hemorrhage of brain metastasis is a poor prognostic factor in patients with hepatocellular carcinoma. We conducted a retrospective cohort study to compare overall survival between hemorrhage and no-hemorrhage groups of hepatocellular carcinoma patients with brain metastasis. Hepatocellular carcinoma patients with brain metastasis treated between June 2000 and June 2016 at ...
