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 hipoplastik/aplastik 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 hipoplastik/aplastik PCoA anomalisi olan olguların 17'sine (%37,8) anterior sirkülasyon enfarktı, 14 olguya (%31,1) posterior sirkülasyon enfarktı tanısı konulmuştur. Tek taraflı hipoplastik/aplastik ACA A1 segmenti tanısı alan 50 olgunun 13'üne (%26) anterior sirkülasyon infraktı, 10 olguya (%20) posterior sirkülasyon infraktı tanısı konulmuştur. 27 olguya (%54) iskemik inme tanısı konulmamıştır. Bilateral hipoplastik/aplastik ACA A1 segmenti tanısı alan 2 olgunun her ikisinde de anterior sirkülasyon infarktı mevcuttu. Tek taraflı FPCA anomalisi tanısı alan 13 olgunun 4'üne (%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.

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.
