Ultrasonography monitoring with Superb Microvascular Imaging during cerebrovascular surgery.

Introduction: Ultrasonography (US) is used as a real-time dynamic imaging modality during neurosurgery. A novel Doppler US technique, Superb Microvascular Imaging (SMI), can be used to visualize low-velocity flow of small vessels at high resolution with high frame rates. We visualized vessel flow using this US SMI technique and contrast agent during cerebrovascular surgery.

Infective Arteritis Manifesting as an Acute Subdural Hematoma.

We encountered a 60-year-old man who had been diagnosed with heart failure of valvular disease and infective endocarditis; he was being treated with intravenous antibiotics and diuretics. On the 12th hospital day, he suddenly lost consciousness; computed tomography showed a right-sided huge subdural hematoma (SDH) with brain herniation. He died after invasive care was discontinued.

Clinical outcomes of intracerebral hemorrhage in hemodialysis patients.

Background: Chronic renal failure (CRF) is associated with a high incidence of stroke. In particular, the mortality rate for intracerebral hemorrhage (ICH) patients with hemodialysis (HD) due to advanced stage CRF is high, and the annual number of such cases is increasing. Therefore, we retrospectively investigated 5 years of clinical data from patients with ICH in our institution to reveal differences in the clinical courses of HD and non-HD patients and to identify risk factors for poor outcomes in ICH patients with HD.
