Methods Seventy-two patients with TIA collected from years 1959 to 1977 were followed up by means of face-to-face communication with the patients themselves or their families till year 1998. According to the principle of life table, the recurrence of TIA after the first attack, occurrence of complete stroke and myocardial infarction, fatality rate, causes of death and survival rate every year, and the 95% confidence interval were calculated and analyzed.Results Till 1998, the recurrent rate of TIA in 72 patients was 27.9%, the occurrence rate of complete stroke 65.7%, and that of myocardial infarction 8.4%. The fatality rate was 72.7%. Among the deaths, 2 (3.8%) patients died of myocardial infarction. It was shown from the study that the main cause of death was complete stroke, accounting for 59.6% of all deaths, with the main cause in non-elderly patients being cerebral hemorrhage, and that in the elderly patients being cerebral infarction. The 20-year survival rate was 39.9% and its 95% confidence interval was (28.4%, 51.4%). Nineteen cases were indicated for neurovascular surgical operation, accounting for 26.6% of the 72 patients. Conclusions In the long-term follow-up study, about one third of the patients had the recurrent TIA. The occurrence rate of complete stroke was markedly higher than that of myocardial infarction. Presumably, the effect of neurovascular surgical operation on the prevention of complete stroke in patients with TIA is limited.展开更多

Methods： A total of 71 PCIV cases were randomly allocated into an acupuncture group （37 cases） and a medication （oral Flunarizine Hydrochloride） group （34 cases）. After 6 weeks of treatment, the therapeutic efficacies in the two groups were analyzed. Results： After treatment, the mean blood flow velocities （VM） of both the vertebral artery （VA） and the basilar artery （BA） in acupuncture group were significantly increased, showing statistical differences when compared with the pre-treatment result of the same group （P〈0.05）; despite some decrease in pulsatility index （PI） after treatment, there was no statistical difference when compared with the pre-treatment result. After treatment, the mean blood flow velocities of both VA and BA in the medication group were increased, showing statistical differences when compared with the pre-treatment result of the same group （P〈0.05）; there was no statistical difference in PI before and after the treatment （P〉0.05）. Regarding the improvement of VM, the acupuncture group was superior to the medication group, showing a statistical difference （P〈0.05）; there was no statistical difference in PI improvement between the two groups. Considering from the clinical efficacy, both acupuncture and medication are effective. However, acupuncture obtained a significantly better effect than medication （P〈0.05）. Conclusion： Acupuncture therapy can posterior circulation ischemia vertigo. obtain a better effect than oral Flunarizine Hydrochloride for展开更多
