Thunderclap headache, a severe headache which is maximal in intensity at onset, is associated with numerous underlying disorders, including subarachnoid hemorrhage, unruptured intracranial aneurysm, cervical artery dissection, cerebral venous sinus thrombosis, stroke, intracranial hemorrhage, reversible cerebral vasoconstriction syndrome, and reversible posterior leukoencephalopathy. After excl...

OBJECTIVE Low serum total cholesterol levels are associated with an increased risk of symptomatic intracerebral hemorrhage and with presence of asymptomatic cerebral microbleeds. The relative contribution of lipid fractions to these associations is unclear and requires investigation. We determined whether serum HDL-cholesterol, LDL-cholesterol, and triglycerides are associated with risk of intr...

Intracerebral hemorrhage (ICH) is the most feared risk of systemic thrombolysis for ST-elevated myocardial infarction, pulmonary embolism, or acute ischemic stroke. Clinical, radiological, and pathological evidence suggests that cerebral small vessel disease and, in particular, cerebral amyloid angiopathy (CAA) may contribute to or in some cases directly underpin thrombolysis-related intracereb...

BACKGROUND AND PURPOSE Transcranial doppler ultrasound (TCD) is used after subarachnoid hemorrhage to detect cerebral vasospasm and is often treated with induced hypertension. Cerebral autoregulation, however, may be disturbed in this population, raising the possibility that TCD velocities may be elevated by induced hypertension. To study this possibility, we performed continuous TCD monitoring...

Cerebrovascular responses to a 20% volume hemorrhage were studied in chloralose-anesthetized dogs with the Doppler cerebral venous outflow method. Arterial PCO2, PO2, and pH were held constant by servocontrol of ventilation. The experimental results were divided into 2 groups as determined by the spontaneous responses of mean arterial pressure (MAP) to hemorrhage. In Group 1 (n = 11), steady st...

Cerebral vasospasm and delayed cerebral ischemia are common complications associated with subarachnoid hemorrhage (SAH) outcomes. Various modalities can be used to evaluate detect after SAH. Transcranial Doppler (TCD) ultrasonography as an appropriate bedside dynamic monitoring tool screen for the presence progression of in patients This article briefly reviewed severity SAH pathophysiology vas...

Cranial sonography revealed cerebral hemorrhage in three of seven neonates with erythroblastosis fetalis. Among the three infants with hemorrhage, one was 28 weeks gestational age and experienced germinal matrix hemorrhage with ventricular extension, a finding typical of cerebroventricular hemorrhage in the premature population. The other two infants with intracranial hemorrhage were more gesta...

BACKGROUND AND PURPOSE Patients with hereditary hemorrhagic telangiectasia (HHT) are at risk for developing cerebral vascular malformations and pulmonary arteriovenous fistulae. We assessed the risk of neurological dysfunction from these malformations and fistulae. METHODS Three hundred twenty-one consecutive patients with HHT seen at a single institution over a 20-year period were studied. A...

Methods We retrospectively studied 34 patients with cerebral hemorrhage (23 men, 11 women, mean age 64 ± 15 years) hospitalized in ICU of the KAT hospital in Athens. Demographic data of patients, the type, severity and treatment of cerebral hemorrhage, the predisposing factors, the comorbidities, the complications during ICU hospitalization and the outcome were recorded. T-student and chisquare...

Headache of subacute onset, associated with other signs of increased intracranial pressure, represents the most frequent symptom of cerebral thrombophlebitis. We report a case of subarachnoid hemorrhage as a rare presentation of cerebral thrombophlebitis. Unfractionated intravenous heparin treatment resulted in resolution of subarachnoid hemorrhage on control brain CT scan and quick clinical re...
