Pigmented villonodular synovitis of synovial tumors and tumor-like lesions and differential diagnosis of Experience


Check the condition of the hospital equipment joint, synovial derived preoperative or postoperative pathology-based disease diagnosis and differential diagnosis of the primary means. 3.2 pigmented villonodular synovitis of as a benign lesion,ralph lauren polo, with exudative synovitis, tumor-like proliferation of the main pathological changes, and lesions of bone and soft tissue even dip, can not be considered to be malignant . Generally only do partial synovectomy, soaked to the bone organizers are required to do partial debridement, because diffuse lesions, complete resection difficult, to do radiation therapy for relapsed patients, often to obtain a satisfactory therapeutic effect. Transcranial Doppler ultrasound diagnosis of intracranial hypertension and brain death in clinical analysis Hegang City, Heilongjiang Province People's Hospital (154 101) Liyan Yu Lvzong Chang He Wenxia Yuan Fengqin Keywords transcranial Doppler ultrasound (D) increased intracranial pressure normal brain death human cranial and cranial contents to maintain a dynamic balance between the pressure, when the CSF pressure> 180mm0 (1.77kP ~, this steady-state equilibrium was destroyed, as increased intracranial pressure. nl increased intracranial pressure caused by a post- series of pathophysiological changes, the serious consequences of intracranial circulatory arrest, due to ischemia, hypoxia caused by brain death a cause of 1.1 cerebral edema, intracranial lesions, CSF malabsorption caused by hydrocephalus or increased secretion, etc., the smaller the cranial cavity, cranial contents volume increased, leading to increased intracranial pressure foot. 1.2 If the progressive increase of intracranial pressure can not control, the continuing recovery of consciousness, leading to brain death is 2.1 2 clinical attack of intracranial pressure increased when the main symptoms of headache, vomiting and acute intracranial hypertension, severe headache, with jet-like vomiting; papilledema, abducens nerve palsy, focal neurological signs worsened herniation can cause severe disturbance of consciousness 2.12, including the brain stem, including brain death is the irreversible loss of all skills, state of the diagnostic criteria of brain death prepared the country is different, just try our diagnostic criteria are: ① deep coma; ② Consumers husband brainstem reflex ; ③ no spontaneous breathing: ④ EEG straight or transcranial Doppler ultrasound showed brain death waveform [l] 3 increased intracranial pressure, the D performance with increased intracranial pressure, cerebral perfusion pressure decreased, blood flow resistance increased blood flow velocity decreased, mainly in significantly decreased diastolic blood flow velocity, pulsatility index increased, the high flow rate was low pulsatility index spectrum in patients with increased intracranial pressure, when after shunt surgery, decreased intracranial pressure,diesel jeans sale, D shows blood flow to speed, pulsatility index decreased this paper, l0 cases of increased intracranial pressure monitoring of patients with bilateral middle cerebral artery blood flow, found that D spectrum of changes in intracranial pressure is very sensitive to this high resistance in severe low-flow spectrum, diastolic flow velocity can be reduced to zero, when given mannitol decompression, ventricular decompression drainage and other measures, the improvement in intracranial pressure, D spectrum of clinical improvement and improvement is consistent when the disease continues to increase, intracranial pressure continues to rise,abercrombie uk, the further deterioration of clinical symptoms, and the emergence of brain death, D has characteristic spectral changes. 4 Na clinical diagnosis performance when the death of D near the diastolic blood pressure increased intracranial pressure, the intracranial blood flow velocity tends to the effective 0 when increased intracranial pressure between the diastolic and systolic blood pressure, extravascular pressure enough to make the whole system of cerebral small vessel lumen in all diastolic collapse, loss of compensatory mechanisms. changes in brain death a typical spectrum there are three kinds: ① systolic forward flow with diastolic reverse flow, the spectral shape is not exactly the same, may have diastolic early and late reverse flow. diastolic blood flow in the mid-small positive or no blood flow. may also have full reverse diastolic blood flow in clinical practice can be seen,diesel jean sale, some patients still weak breathing occurs when the diastolic reverse flow, foreign countries also have similar false-positive reports, these patients may still survive. that forward diastolic blood flow to the more simple the reverse flow occurs more accurate diagnosis of brain death . can not alone make D spectrum on the diagnosis of brain death must be combined with clinical, but if there D spectrum diastolic reverse flow,Nike Schuhe Günstig, the poor prognosis of patients prompted if undetectable blood flow, many more to be experienced by the e doctors repeatedly checked, undetectable by the temporal window, the window to be checked by eye. really no blood flow signals can be combined with clinical judgments.
