Thirty Years of Transcranial Doppler: What has changed?

Prof. Rune Aaslid, PhD

This year (2011) marks the 30th anniversary of the first application of transcranial Doppler (TCD). In the summer of 1981, I was fortunate to be invited to do research at the Department of Neurosurgery in Bern by Prof. Helge Nornes—a pioneer in the study of cerebral hemodynamics using electromagnetic flowmetry and intraoperative Doppler. Before accepting the position, I decided to try to get Doppler signals from the intracranial vessels using a 2MHz pulsed Doppler system that I happened to have on loan in my laboratory (the Doppler was used for developing a full scale physical model of the left ventricle and aorta for the Norwegian Underwater Institute).

Днес по инициатива на сдружение “Българска асоциация по невросонология и мозъчна хемодинамика” (БАНМХ) в зала „София” на столичния хотел “Кемпински-Зографски” от 18,30 часа ще се проведе международен научен форум, посветен на ултразвуковата класификация на каротидните стенози. Симпозиумът е под егидата на Изследователската група по невросонология към Световната федерация по неврология. Гост-лектор  ще бъде президентът на Изследователската група по невросонология проф. Манфред Капс.

Treatment of Acute Ischemic Stroke with Thrombolysis in Bulgaria

Stroke is a socially significant disease characterized by high incidence, morbidity and mortality, causing severe disability worldwide. According to the World Health Organization there are 15 million new cases with stroke per year in the world; 5 million of them die and five million remain permanently disabled. In Europe, the annual stroke death is approximately 650,000 and mortality is higher in Central and Eastern Europe compared to Northern, Southern and Western Europe. In the European Union the total cost of cerebrovascular diseases amount 192 bilion euro annually; around 57% of them are health care costs, 21% are due to incapacity to work and 22% due to informal care of stroke survivals [9].
