Orbital Doppler sonography findings in cases of brain death.
In this study, we investigated the blood flow velocity changes in orbital arteries by using Doppler sonography in eight patients with brain death. Peak-systolic and end-diastolic velocities and resistive indices of the ophthalmic and central retinal arteries were evaluated. We observed the absence or reversal of end-diastolic blood flow in these arteries. To our knowledge, this finding has not ...
متن کاملDiagnosis of brain death by transcranial Doppler sonography.
Delays in diagnosis of brain death have definite consequences for the organ retrieval and transplantation process. It is advisable to use accurate diagnostic methods. Transcranial Doppler sonography is a well-accepted technique for diagnosing cerebral circulatory arrest. However, in some cases, the access to the intracranial circulation via the temporal window is difficult. In 43 brain-dead pat...
متن کاملDoppler and Duplex Sonography for the Diagnosis of the Irreversible Cessation of Brain Function ("Brain Death"): Current Guidelines in Germany and Neighboring Countries.
Extra- and transcranial sonography of brain-supplying arteries is accepted worldwide in brain death protocols as a valid "ancillary" method of proving brain circulatory arrest. Color-coded duplex sonography and CT angiography have been newly incorporated in the fourth update of the German Medical Association's guidelines for the determination of the irreversible cessation of brain function ("br...

Infertility is defined as the failure to conceive a desired pregnancy after 12 months of unprotected intercourse, and affects 10 percent of married couples. The causes of infertility can involve one or both partners. Causes of female infertility: • Fallopian tube factors (damage or blockage due to salpingitis, EP) • Ovulation disorders (PCOS ,Early menopause ) • Uterine factors • Intrauterine l...
متن کاملRole of Transcranial Doppler Sonography in Confirmation of Brain Death
The aim of the study was to determine the specificity and sensitivity of Transcranial Doppler Sonography (TCD) as a confirmatory test for diagnosis of brain death and to assess the possibility of adding this test to the protocol for diagnosis of brain death in ICU. TCD examination was done in 20 patients (group I) with brain death confirmed either by clinical assessment and EEG (17 patients) or...
