Abstract
This is a prospective descriptive research which was carried out in Imam Khomeini Hospital related to Tehran University during two years (1375-1377) in order to study the incidence of internal carotid stenosis in patients who suffered from TIA ot minor stroke. It was evaluated by duplex sonography. Risk factors of carotid stenosis were studied. 1052 patients who had cerebrovascular accident admitted to Imam Khomeini Hospital and 100 of them who suffered from TIA or minor stroke were selected. The data was gathered by questionnaire and analysed. According to the results of the research, the incidence of internal carotid stenosis was 81%. The incidence of severe stenosis (>70%) was 20%, moderate stenosis (30-69%) was 36%, and mild stenosis (<29%) was 44%. There was a significant relationship between hyperlipidemia, diabetes mellitus and alcohol consumption, with internal carotid stenosis. There was no significant relationship between hypertension and cigarette smoking with internal carotid stenosis. There was a significant relationship between history of angina pectoris or myocardial infarection with severity of internal carotid stenosis. We suggest to consider duplex sonography as a part of evaluation of patients who suffer from TIA or minor stroke for screening of severe internal carotid stenosis. Control and treatment of risk factors are useful preventive measures that can reduce the incidence of carotid artery stenosis and cerebrovascular accidents

Volume 66, Issue 7 (10-2008)
Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Approximately 2-15% of the global population suffers from migraine headaches. Since acupuncture is one of the treatments for this disorder, the aim of the present study was to assess the effectiveness of this modality on patients with migraine.
Methods: In this experimental interventional study, we enrolled 180 patients with migraine headache attacks at a documented frequency of at least 2 attacks during last 6 months. For all patients, the number, duration and intensity of the headaches were recorded before treatment. To treat the patients, the point with maximal pain was first determined and the meridian was distinguished. Then, the related acupoints were found and stimulated by percutaneous electrical acupuncture for several minutes. The procedure was repeated once per week for six weeks. After completion of all treatment sessions, the patients were visited and questioned about the number, duration and the intensity of headaches.
Results: The mean of number of attacks (9.55±8.26 vs. 3.50±6.77, p=0.001), the mean duration of each attack (9.11±6.59 vs. 3.33±3.65, p=0.001) and the intensity of the attacks (1.83±0.38 vs. 0.61±0.78, p=0.001) were significantly lower after treatment.
Conclusion: Application of acupuncture in patients with migraine headaches is associated with a significant decrease in the mean number, duration and intensity of attacks. Thus, this method of treatment is strongly recommended for migraine headache.


Transient ischemic attacks and presence of an acute brain lesion in diffusion-weighted MRI: study of 50 patients
Sabeti M, Naser Moghadasi A, Aloosh M, Paknejad Sm, Toghae M,
Volume 70, Issue 7 (10-2012)
Abstract

Background: Finding an acute brain lesion by diffusion-weighted (DW) MRI upon an episode of transient ischemic attack (TIA) is a predictor of imminent stroke in the near future. Therefore, exploring risk factors associated with lesions in DW-MRI of the brain is important in adopting an approach to TIA management. In the current study, we tried to determine the risk factors associated with lesions in DW-MRI of the brain in patients experiencing TIA episodes.
Methods: Fifty patients with TIA were recruited consecutively in Sina Hospital, Tehran, Iran, over a 6-month period between July 2008 and January 2009. All of the patients underwent a complete neurological examination and laboratory tests. Brain DW-MRIs were performed for all the patients within 72 hours of a TIA episode.
Results: DW-MRI revealed an acute lesion in 16% of the participants. There was a significant correlation between presence of an acute lesion in DW-MRI and TIA duration, history of diabetes mellitus and presence of unilateral facial palsy (P=0.0003, P=0.02 and P=0.008, respectively). Other variables such as age, hypertension, hyperlipidemia, past history of TIA, headache, vertigo, and sensory or visual disturbances had no significant relation with the presence of an acute lesion in DW-MRI.
Conclusion: Duration of TIA, presence of diabetes mellitus and unilateral facial palsy are risk factors for an acute lesion in DW-MRI, meaning that patients with such risk factors are at risk for stroke in the near future.


Investigation the frequency of asymptomatic hemorrhagic transformation of infarction in CT scan of acute ischemic stroke patients

Volume 76, Issue 12 (3-2019)
Abstract
Background: Asymptomatic hemorrhagic transformation infarct (AHTI) is known as a complication of ischemic attack and maybe occurs in the entire stroke. However, the role of AHTI in the result of the treatment is still not clear, because it is based on the definition of an asymptomatic and not identifiable. The aim of this study was assessment and evaluation frequency of AHTI in acute ischemic stroke patients.
Methods: This prospective cross-sectional study was done in Neurologic Department, Tehran University of Medical Sciences, Tehran, Iran, from April 2015 to April 2016. Second evaluation was done about new neurologic signs and symptoms ten days after stroke. In addition, brain CT scan was used to diagnose of hemorrhagic event in infarct area. If the hemorrhagic event was occur in different area, the patient was consider as a non-hemorrhagic transformation and excluded from the study. Other exclusion criteria include intracranial hemorrhage (ICH), trauma to the head during admission, cerebral vein thrombosis, coagulation disorder, anti-coagulant (heparin, warfarin) administration, induced transformation within 10 days of onset of ischemia, lacunar ischemic and unobservable in thirty T-brain scan, patient's lack of referral for examination and CT scan 10 days after the onset of symptoms, died before CT was considered.
Results: Three hundred and eighty seven patients had inclusion criteria. 249 cases were excluded due to lost following, vein thrombosis of the brain, lacunar ischemia, anti-coagulants recipient (heparin, warfarin), asymptomatic hemorrhagic transformation and death. Finally, 138 cases (86 men, 52 women) with 66.61±9.37 years (50-101 years) were participated in data analysis. Frequency of positive CT scan was evaluated for ischemic stroke evidence in two stages. Of the 138 patients who participated in the study, 75 (54.3%) were positive in the first and 63 (45.7%) cases in the second time. 27 cases (19.6%) had AHTI.
Conclusion: Coronary artery bypass graft (CABG) had significant correlation with ATHI in acute ischemic attack. However, stroke history correlated with decreasing of ATHI. Concerning smoking and consuming the results showed that smoking did not affect the asymptomatic hemorrhagic transformation. Also, the results showed that the use of aspirin and Plavix also had no significant effect on increasing the incidence of ATHI.
