Case Reports
Internal jugular venous thrombosis as a complication after an elective anterior cervical discectomy: case report.
Anterior cervical discectomy is one of the most common spine procedures in neurosurgery. Various complications, including hoarseness, hematoma, and dysphagia, have been reported in the literature. We report the first case of internal jugular venous thrombosis after an elective anterior cervical discectomy. ⋯ This is the first report of internal jugular venous thrombosis after an elective anterior cervical discectomy. Internal jugular venous thrombosis should be considered in the differential diagnosis of a patient presenting with cervical swelling after an anterior cervical discectomy.

To correlate high-resolution magnetic resonance imaging (MRI) with immunohistopathology in the injured human spinal cord. ⋯ MRI, the only imaging technique that currently provides useful information on the spinal cord parenchyma after trauma, is rapidly evolving. High-field scanners of up to 9.4 T are being clinically tested. The present postmortem investigation of an isolated spinal cord specimen demonstrates the precise correlation that can be achieved between imaging and pathology. In future investigations, this type of technique can lead to a more precise description of spinal cord injuries and their consequences in remote tissue. Translation into the clinical setting will improve diagnosis and follow-up of spinal cord injured patients.

In this study, we evaluated patients' clinical outcome and recurrence rates at long-term follow-up after aggressive microsurgical resection of cranial base chordomas. ⋯ Aggressive microsurgical resection of chordomas can be followed by long-term, tumor-free survival with good functional outcome. A more conservative strategy is recommended in reoperation cases, especially after previous radiotherapy, to reduce postoperative complications.

The aim of the study was to correlate absolute cerebral blood flow (CBF) and mean transient time (MTT) measured by dynamic perfusion computed tomographic (PCT) scanning with the clinical course, vasospasm severity, and perfusion abnormality in patients with cerebral vasospasm after aneurysmal subarachnoid hemorrhage. ⋯ The present study suggests that, in general, quantitative measurements of rCBF and regional MTT by PCT show high concordance rates with the clinical course, vasospasm severity, and hemodynamic impairments in patients with cerebral vasospasm aneurysmal subarachnoid hemorrhage.

Comparative Study
Transcranial Doppler grading criteria for basilar artery vasospasm.
Transcranial Doppler (TCD) criteria for basilar artery (BA) vasospasm are poorly defined, and grading criteria for vertebrobasilar vasospasm are unavailable. The purpose of the present study was to define TCD grading criteria for BA vasospasm on the basis of the absolute flow velocities and the intracranial to extracranial flow velocity ratios for the posterior circulation, and to improve the sensitivity and specificity of TCD for diagnosis of BA vasospasm. ⋯ The BA/VA ratio improves the sensitivity and specificity of TCD detection of BA vasospasm. On the basis of the BA/VA ratio and BA mean velocities, we suggest new TCD grading criteria for BA vasospasm.
