Abstract：Objective:Toobservetheclinicalefficacyofhyperbaricoxygenforposteriorcirculationischemicvertigo ( PCIV)caused by small vascular lesions. Methods:From August in 2014 to February in 2015,80 cases in hospital with with posterior circulation ischemic vertigo,diagnosed by magnetic resonance imaging( MRI ),magnetic resonance angiography (MRA),diffusion weighted imaging(DWI),were randomly divided into hyperbaric oxygen treatment group(40 cases)and control group(40 cases). Assessment Rating Scale(DARS)score,vertigo disorder questionnaire(DHI)score and transcranial doppler ultrasonography( TCD)were observed before and after the treatment 7 days,14 days. Results:Hyperbaric oxygen ther-apy group compare to control group,can significantly improve the clinical symptoms in patients with vertigo,DARS and DHI scores of patients in two groups has obvious change before and after therapy(P<0. 01). Two groups of patients with TCD changes as a result,before expanding set of treatment the abnormal rate was 82. 22%(37/45),the control group before treat-ment the abnormal rate was 86. 67%(39/45),expansion treatment group after treatment the abnormal rate was 15. 67%(7/45),the control the abnormal rate was 37. 78%(17/45). Expansion and prompt treatment and classical treatment all can im-prove the hemodynamics of vertebral basilar artery system,but the effect of hyperbaric oxygen treatment group is more signifi-cant. Conclusion:Hyperbaric oxygen treatment can quickly and efficiently improve the small vascular lesions caused by posteri-or circulation ischemic symptoms of dizziness.
