Abstract:

 Our aim in this study is examining the frequency of posterior communicating artery PCoM, Anterior Cerebral Artery A1 segment ACA AI and Fetal type posterior cerebral artery FPCA anomalies and their effects on ischemic stroke by retrospectively analyzing examinations of Computerized Tomography Angiography CTA taken in our hospital within 2017. 22 cases 26.5 diagnosed with bilateral hypoplastic  aplastic PCoA anomaly, were diagnosed with anterior circulation infarct, 24 cases 28.9 were diagnosed with posterior circulation infarct, but 37 cases 44.6 were not diagnosed with ischemic stroke. 17 37.8 of the cases who have unilateral hypoplastic  aplastic PCoA anomaly, were diagnosed with anterior circulation infarct, 14 cases 31.1 were diagnosed with posterior circulation infarct. 13 26 of 50 cases diagnosed with unilateral hypoplastic  aplastic ACA A1 segment, were diagnosed with anterior circulation infarct, 10 cases 20 were diagnosed with posterior circulation infarct. 27 cases 54 were not diagnosed with ischemic stroke. Both of 2 cases diagnosed with bilateral hypoplastic  aplastic ACA A1 segment, had anterior circulation infarct. 4 30.8 of 13 cases diagnosed with unilateral FPCA anomaly, were diagnosed with anterior circulation infarct, 3 cases 23.1 were diagnosed with posterior circulation infarct, 6 cases 46.2 did not have ischemic stroke symptoms. In conclusion, even though these variations role in optimum stroke prophylaxis in individuals having one or more stroke risk factors, has not determined yet, there is no doubt that clinical researcher will eliminate these uncertainties in future studies.

 Bu çalışmadaki amacımız Bilgisayarlı Tomografi Anjiyografi BTA incelemelerini retrospektif olarak analiz ederek Posterior Komünikan Arter PCoM, Anterior Serebral Arter A1 segmenti ACA AI ve Fetal Tip Posterior Serebral Arter FPCA anomalilerinin sıklığını ve iskemik inme üzerindeki etkilerini incelemektir. Çalışma retrospektif olarak planlandı ve 2017 yılında BTA çekilen hastalar çalışmaya dahil edildi. Bilateral hipoplastikaplastik PCoA anomalisi tanısı alan 22 olguya 26,5 anterior sirkülasyon infraktı, 24 olguya 28,9 posterior sirkülasyon infraktı tanısı konulmuştur, 37 olguya 44,6  iskemik inme tanısı konulmamıştır. Tek taraflı hipoplastikaplastik PCoA anomalisi olan olguların 17sine 37,8 anterior sirkülasyon enfarktı, 14 olguya 31,1 posterior sirkülasyon enfarktı tanısı konulmuştur. Tek taraflı hipoplastikaplastik ACA A1 segmenti tanısı alan 50 olgunun 13üne 26 anterior sirkülasyon infraktı, 10 olguya 20 posterior sirkülasyon infraktı tanısı konulmuştur. 27 olguya 54 iskemik inme tanısı konulmamıştır. Bilateral hipoplastikaplastik ACA A1 segmenti tanısı alan 2 olgunun her ikisinde de anterior sirkülasyon infarktı mevcuttu. Tek taraflı FPCA anomalisi tanısı alan 13 olgunun 4üne 30,8 anterior sirkülasyon enfarktı tanısı konulmuştur, 3 olguya 23,1 posterior sirkülasyon enfarktüsü tanısı konulurken, 6 olguda 46,2 iskemik inme semptomu saptanmamıştır. Sonuç olarak, bir veya daha fazla inme risk faktörüne sahip bireylerde bu varyasyonların optimum inme profilaksisindeki rolü henüz belirlenmemiş olsa da, klinik araştırmacıların gelecekteki çalışmalarda bu belirsizlikleri ortadan kaldıracağından şüphe yoktur.
