Primary intracerebral and subarachnoid hemorrhage. An approach to diagnosis and therapy.
The diagnosis of primary intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) has become easier with the advent of modern imaging techniques. The incidence of ICH has declined, while SAH has remained relatively constant. The prognosis for both disorders remains dismal and the mortality rate is substantially higher than that observed with ischemic stroke. Early imaging with CT or MRI is important for rapid and accurate diagnosis. General medical management in a skilled nursing facility should be available for patients who are not moribund. Therapy for ICH is predominantly supportive and effective medical and surgical intervention remains elusive. For SAH, calcium channel blockers may reduce cerebral ischemic complications related to vasospasm, but effective medical therapy to prevent rebleeding has not been established. Early surgery after SAH should be considered in clinically stable patients. Many challenges remain regarding the prevention and treatment of both these cerebral hemorrhage subtypes.
