Multidirection rotating-sucking device for intracranial hematoma / 医疗卫生装备

This device is an apparatus which can remove intracranial hematoma rapidly and offer a mild damage to the brain tissue.So,with the device,the hematoma which cased by hypertensive cerebral hemorrhage can be removed effectively,and the damage caused by cerebral hemorrhage can be lighten,and the mortality can be reduced,This device is making up of overcoat tube,rotation-sucking tube,guide tube,and spray tube,which can be used for rotating broken suction and multidirection spraying washing.Used clinically to treat more than 400 patients with hypertension cerebral hemorrhage,the device can lighten space occupying effect of intracranial hematoma rapidly,and thus many patients are saved.It's indicated this device is the most effective device for removing brain hematoma at present.

Diffusion-weighted MR imaging findings of intracerebral hematoma

PURPOSE: To evaluate diffusion-weighted imaging findings of intracerebral hematoma according to the time sequence. MATERIALS AND METHODS: Seventeen patients with intracerebral hematoma were studied. Diffusion weighted images using 1.5 tesla MRI machine were obtained with b-value of 1000 sec/mm2. The patients were grouped as hyperacute stage(within 12 hours, 5 patients), acute stage(within 3 days, 4 patients), subacute stage(within 3 weeks, 4 patients), and chronic stage(after 3 weeks,4 patients). The signal intensities were analysed as bright, high, iso, low and dark at the central and peripheral portions of the hematoma in each stage, and compared with those of T2 and T1 weighted images. RESULTS: The signal intensities of the central and peripheral portion of the intracerebral hematoma on diffusion-weighted images were high and dark in hyperacute stage, dark and high-bright in acute stage, and high-bright and dark in subacute and chronic stages. The patterns of signal change of hematoma on diffusion-weighted image according to the time sequence were similar to those on T2-weighted image, but 1 early and prominently. CONCLUSION: The intracerebral hematoma on diffusion-weighted image showed unique central and peripheral signal intensity according to the time sequence. Central portions show high to bright signals in hyperacute, subacute and chronic stage, and dark signal in acute stage, and peripheral portions show dark signals in hyperacute, subacute and chronic stage, and high to bright signal in acute stage.
