Angiographic view in a 41-year-man who presented 7 days earlier with subarachnoid hemorrhage from a ruptured anterior communicating artery (ACA) aneurysm (which was treated with surgical clipping). The most common cause for the rupture is uncontrolled hypertension (high blood pressure). A small tube called a catheter can sometimes be threaded up through a major artery in an arm or leg and guided into the brain tissue, allowing the surgeon to use cameras to see the problem.Once the catheter is guided to the source of the bleeding, it deposits a mechanical agent, such as a coil, to prevent further rupture.This type of procedure is endovascular, meaning that the surgeon gains access through the vascular system, making it less invasive than conventional surgical treatment.Sometimes surgery is required to secure a blood vessel at the base of the aneurysm. Stroke may result in loss of cerebral autoregulation of cerebral perfusion pressure.Intensive BP reduction (target BP < 140 mm Hg systolic) early in the treatment of patients with intracerebral hemorrhage appears to lessen the absolute growth of hematomas, particularly in patients who have received previous antithrombotic therapy, according to a combined analysis of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trials 1 and 2 (INTERACT).Suggested agents for use in the acute setting are beta blockers (eg, labetalol) and angiotensin-converting enzyme inhibitors (ACEIs) (eg, enalapril).

Hyperacute stroke: evaluation with combined multisection diffusion-weighted and hemodynamically weighted echo-planar MR imaging. Studies of recombinant factor VIIa (rFVIIa) have yielded disappointing results. Guidelines for the management of aneurysmal subarachnoid hemorrhage: a guideline for healthcare professionals from the American Heart Association/american Stroke Association. The ICH score: a simple, reliable grading scale for intracerebral hemorrhage.

Prevalence of stroke--United States, 2005.

Prediction of hemorrhagic transformation in acute ischemic stroke: role of diffusion-weighted imaging and early parenchymal enhancement.

Frontal view from a cerebral angiogram in a 41-year-man who presented 7 days earlier with subarachnoid hemorrhage from a ruptured anterior communicating artery (ACA) aneurysm (which was treated with surgical clipping). Correlation of apparent diffusion coefficient and computed tomography density in acute ischemic stroke.

Indeed, 2 studies have reported worse outcomes in patients who did not have a documented seizure but who received antiepileptic drugs (primarily phenytoin).The 2010 AHA/ASA guidelines do not offer recommendations on prophylactic anticonvulsants, but suggest that continuous EEG monitoring is probably indicated in patients with intracranial hemorrhage whose mental status is depressed out of proportion to the degree of brain injuryProphylactic anticonvulsant therapy has been recommended in patients with lobar hemorrhages to reduce the risk of early seizures. Rapidly stabilize vital signs, and simultaneously acquire an emergent computed tomography (CT) scan. Follow-up cerebral angiogram after coil embolization in a 57-year-old man with a left distal internal carotid artery aneurysm. A small amount of residual filling is noted at the proximal neck of the aneurysm, which may thrombose over time. Feigin VL, Lawes CM, Bennett DA, Anderson CS. Chapman AB, Rubinstein D, Hughes R, Stears JC, Earnest MP, Johnson AM, et al. Strokes are a leading cause of long-lasting injury, disability, and death. von Kummer R, Meyding-Lamadé U, Forsting M, Rosin L, Rieke K, Hacke W, et al. Intubate and hyperventilate if intracranial pressure is elevated, and initiate administration of mannitol for further control. The most common cause is an Immediate emergency care is crucial for a hemorrhagic stroke. If the stroke is caused by an AVM, surgery may be used to remove it. Preoperative evaluation of carotid artery stenosis: comparison of contrast-enhanced MR angiography and duplex sonography with digital subtraction angiography. 2001 Ability to use duplex US to quantify internal carotid arterial stenoses: fact or fiction?. For patients with stroke, the combination of an ACE inhibitor and ARB is not recommended (Grade B). Surgical risk as related to time of intervention in the repair of intracranial aneurysms. Patients with renal failure and platelet dysfunction may also benefit from the administration of desmopressin (DDAVP). Brown PB, Zwiebel WJ, Call GK. Early treatment and preventive measures can reduce the brain damage that occurs as a result of a stroke. Intraventricular hemorrhage is also noted layering in the left occipital horn. The need for invasive intracranial pressure monitoring and for emergent cerebral angiography should be assessed by the neurosurgeon. There is also a mild, lobulated dilatation of the cavernous left ICA. Flaherty ML, Woo D, Haverbusch M, Sekar P, Khoury J, Sauerbeck L, et al. The vertebral arteries join to form the basilar artery. PET/SPECT imaging: from carotid vulnerability to brain viability.
