Subarachnoid hemorrhage represents a serious disease with high mortality and morbidity. Two important areas are becoming the central research interest of subarachnoid hemorrhage: cerebral vasospasm and early brain injury. The authors have reviewed the major contributions in experimental subarachnoid hemorrhage documented in the medical literature in the past 5 years. Treatments interfering with...

Intracranial hemorrhage in hemophilia is an unusual manifestation of the disease. The cases hitherto reported have been those of subarachnoid rather than of intracerebral hemorrhage. Indeed, Gunther,2 writing in 1935, stated that no substantiated instance of cerebral hemorrhage in a hemophiliac had been detailed up to that date. Von Limbeck,5 however, is credited with the description of such a ...

conclusions small dose of clopidogrel (75 mg) may lead to rare, life-threatening dah, so physicians should be aware of the possibility of dah after neurointervention in patients who have respiratory distress, worsening alveolar infiltrates accompanied by hemoptysis. introduction diffuse alveolar hemorrhage (dah) is a very rare complication but acute and life-threatening event. clopidogrel has g...

abstract cerebral  aneurysms  are  the  major  cause  of  subarachnoid  hemorrhage.  common  ascribed  etiologies  are hemodynamic  factors  such  as  atherosclerosis,   hypertension,  infection,  trauma,  polycyctic   kidney  disease, connective tissue disorders like ehlers-danlos disease, marfan syndrome, and familial predisposition. however, its association with ankylosing spondylitis (as) i...

Background and Purpose: Cerebral microbleeds are an intracerebral microangiopathy with bleeding tendency found in intracerebral hemorrhage patients. However, studies about cerebral microbleed effects on the prognosis of hypertensive intracerebral hemorrhage patients are rare. We performed a prospective study to discuss not only the risk factors of cerebral microbleed incidence in hypertensive i...

Ruptured intracranial aneurysm usually manifests as subarachnoid hemorrhage (SAH) or SAH with hematoma. Aneurysms that only present with intracerebral hemorrhage or intraventricular hemorrhage are mostly confined to the distal artery. It is very rare that ruptured middle cerebral artery bifurcation aneurysms manifest signs of caudate head hemorrhage extending into the cerebral ventricle. One su...

1. Intracerebral hemorrhage can follow an asymptomatic interval after a trauma and may be due to local or systemic coagulation abnormalities, necrosis of blood vessels in areas of brain injury, transient cerebral dysautoregulation, reduction of intracranial pressure either medically or surgically, or cerebral venous sinus thrombosis. 2. Cerebral venous sinus thrombosis may be easily overlooked ...

PRIMARY cerebral amyloidosis is characterized by deposition of amyloid within the cerebral tissue (e.g., core of neuritic plaques and core of plaques in spongiform encephalopathies) and the cerebral and meningeal blood vessel walls (amyloid or congophilic angiopathy) in the absence of systemic amyloidosis. Primary cerebral amyloidosis has been associated with normal brain aging changes" and wit...

Cerebral amyloid angiopathy is a pathologic condition characterized by the deposition of amyloid in the walls of small vessels in the cerebral cortex and meninges. Intracerebral hemorrhage is common in persons with this condition, but pure subarachnoid or subdural hemorrhage is rarely seen. Recently, the existence of two types of amyloid proteins related to cerebral amyloid angiopathy, beta pro...

The sequential changes in systemic and cerebral hemodynamics, systemic and cerebral oxygen transport and consumption rates, and the regional blood flows (measured with 15 micron microspheres) to the cortical and subcortical brain tissues were determined in nine dogs subjected to graded hemorrhage (10 ml/kg X 4 at 15 min intervals). As hemorrhage progressed, both mean arterial pressure and cardi...
