An 85-year-old male presented with bilateral chronic subdural hematomas (CSDHs) resulting in unilateral oculomotor nerve paresis and brainstem symptoms immediately after removal of both hematomas in a single operation. Initial computed tomography on admission demonstrated marked thick bilateral hematomas buckling the brain parenchyma with a minimal midline shift. Almost simultaneous removal of ...

OBJECTIVE Density of the chronic subdural hematoma (cSDH) is variable. It often appears to be mixed density. Multiple densities of cSDH may result from multiple episodes of trauma. We investigated the frequency of mixed density and the causes of head injuries representing each density. METHODS We could collect 242 cases of chronic SDH. The cSDHs were classified into four groups; hypodensity, ...

Cerebral angiography in patients with nontraumatic lobar intracerebral hemorrhage may or may not uncover the underlying cause of the disorder. The CT and cerebral angiographic studies of 67 consecutive patients with nontraumatic lobar intracerebral hemorrhage were reviewed to assess the relationship between CT pattern and location of hemorrhage and the frequency of diagnostic angiographic findi...

In this study, we measured the level of ferrum ion and VEGF from the hematoma cavity fluid in chronic subdural hematoma (CSDH), and analyzed the relationship between these values with the CSDH diagnosis by MRI. The cranial MRI appearance of each CSDH were classified as hypodense, isodense, hyperdense, or mixed density. The concentrations of ferrum ions in serum and hematoma cavity fluid were me...

To determine the chronologic changes in the MR appearance of brainstem hemorrhage and to evaluate the clinical efficacy of MR imaging, 15 patients were examined with a 0.5-T MR scanner with inversion-recovery (IR) and T2-weighted spin-echo (SE) images. In the acute stage (up to the sixth day), hematomas were hypo- or isointense on IR images and isointense and then hypointense on SE images. In t...

Many uninformed neurosurgeons have regarded surgery for post-traumatic intracranial hematomas as unrewarding. This pessimism is based on the belief that outcome is determined principally by the magnitude of the initial injury and, therefore, frequently remains poor despite optimal surgery. In fact, management of post-traumatic epidural hematoma is one of the most ‘cost-effective’ of neurosurgic...

In (helicopter) emergency medical services, (H)EMS, the prehospital detection of intracranial hematomas should improve patient care and the triage to specialized neurosurgical hospitals. Recently, noninvasive detection of intracranial hematomas became possible by applying transcranial near infrared spectroscopy (NIRS). Herein, second-generation devices are currently available, for example, the ...

Hematoma and seroma formation in surgical wounds has negative effects on wound healing and subsequent morbidity to patients. This is of particular pertinence in cosmetic procedures in which the patient has chosen to undergo surgery electively. Over the past several decades there has been considerable interest in the use of ancillary techniques to assist in closing wounds and achieving hemostasi...

BACKGROUND AND PURPOSE Although previous reports have characterized MR imaging features of spinal epidural hematomas (EDH), few cases have been reported during the acute or hyperacute phase within the first 48 hours. Our goal in this investigation was to correlate the MR imaging features of acute (< or =48 hours) spontaneous EDH with clinical management and outcome. METHODS Eight patients wit...
