Prevalence of Middle Cerebral Artery Stenosis in Bihar Population (A Trans-cranial Doppler Study)

Background: The prevalence and causes of intra cranial arterial stenosis in adults’ stroke patients is largelyunknown. Hence it has become a great clinical challenge for Neuro-physician, neurosurgeon and radiologist tofind out the aetiologies of intra cranial arterial stenosis.Method: 100 patients of aged between 25 to 60 years were selected for study. Their past history and clinicalmanifestations were noted TCD examination was performed with portable machine (multi-drop (R) + DWL),which is a 2MHz power motion single channel TCD, MCA was approached through temporal windows by use ofstandard protocol. stenosis of arteries were defined by the peak systolic flow velocity more than 140 cm/sec forMCA.Results: The highest clinical manifestation was HTN 75%, followed by DM 58%, obesity 52% and hyper cholestremia48%, smoker 38%, CAD 32% and least was PVD 2%. In odds ratio study HTN was highest 8.5, followed by CADratio was 6 and least ratio was alcoholics 1.6.Conclusion: The present study revealed the aggravating factor like HTN, DM, and CAD. Atherosclerosis causesstenosis of MCA and peak systolic velocity more than 140 mc/sec for MCA. Hence the patients having suchclinical manifestations will be more prone for stenosis of MCA.
