Karotid kanal çapı anterior serebral vasküler varyasyonların ve anevrizmaların gösterimesinde yol gösterici olabilir mi?

Öz

Amaç: Karotid kanal çapının kanal çapında değişikliğe neden olabilecek serebral vasküler varyasyon veya anevrizması olmayan hastalarda ölçülmesi ve kanal çapındaki değişikliklerin serebral vasküler anevrizma ve varyasyonların göstergesi olup olamayacağının belirlenmesi amaçlandı. Gereç ve Yöntemler: Yedi yüz beyin-boyun bilgisayarlı tomografi incelemesi retrospektif olarak değerlendirildi. Hastaların 283’ü (40.4%) kadın, 417’si (59.6%) erkekti. İki taraflı karotid kanal çapı ölçüldü. Serebral vasküler varyasyonlar ve anevrizmalar kaydedildi. Bulgular: Sağ karotid kanal çapı tüm hastalarda 5.631±0.502mm, erkeklerde 5.797±0.475mm ve kadınlarda 5.388±0.441mm; sol karotid kanal çapı tüm hastalarda 5.666±0.512mm, erkeklerde 5.825±0.492mm ve kadınlarda 5.432±04.49mm bulundu (p=0.039, <0.001 ve<0.001). Vasküler hipoplazilerde ve posterior komünikan arter (PCom) dışındaki diğer vasküler agenezilerde, Moyamoya hastalığında, anterior ve orta serebral arter anevrizmalarında karotid kanal dardır. Fetal orjinli posterior serebral arter varlığında, PCom dışındaki dolikoektazilerde, anterior komünikan arter (ACom) varyasyon ve anevrizmalarında, internal serebral arter anevrizmasında karotid kanal geniştir. PCom agenezisi, anterior serebral arter A2 trifukasyonu ve ACom fenestrasyonu sağda dar kanal solda geniş kanal ile birliktelik göstermektedir. Sonuç: Karotid kanal çapındaki anormallikler serebral vasküler varyasyon ve anevrizmaların göstergesi olabilir. Karotid kanal anormalliklerinde artan anevrizma insidansı daha geniş hasta gruplarında daha geniş çalışmaların gerekliliğini göstermektedir.

Can carotid canal diameter be an indicator of anterior cerebral vascular variations and abnormalities?

Öz

Aim: To measure the bony carotid canal diameters in people without any cerebral vascular variations or aneurysms that would affect the bony carotid canal and to determine whether the variations of bony carotid canal width could be an indicator of cerebral vascular aneurysyms and variations. Material and Methods: Seven-hundred neck-brain CT angiographies were assessed retrospectively. Of the patients, 283 (40.4%) were women and 417 (59.6%) were men. Bilateral bony carotid canal diameter was measured. Cerebral vascular variations and aneurysms were recorded. Results: Normal canal diameter on the right, in all patients was 5.631±0.502mm, in males 5.797±0.475mm and 5.388±0.441mm in females; on the left side, 5.666±0.512mm overall, 5.825±0.492mm in males and 5.432±04.49mm in females (p=0.039, <0.001 and <0.001 consequently). In vascular hypoplasias, in all other vascular agenesias other than posterior communicating (Pcom) artery, in Moyamoya disease, in anterior and middle cerebral artery aneurysms the canal is narrow. In the presence of fetal originated vessels, in dolichoectasias of vessels, except PCom, in all anterior communicating artery (ACom) variations and aneurysms, in internal cerebral artery aneurysm the canal is wide. PCom agenesia, anterior cerebral artery A2 trifurcation and ACom fenestration is accompanied by narrow canal on the right and wide canal on the left. Conclusion Abnormal canal diameter may indicate to vascular variation or aneurysm. The increased incidence of aneurysm in carotid canal anomalies implicates of the necessity of further studies with larger groups.
