Abstract

AIM: The aim of this study was to report our experience with a 64-channel computerized tomography (CT) scanner as the primary choice on the detection of intracranial aneurysms. Comparison of intracranial aneurysms with the simulated images obtained via three-dimensional computed tomography angiography (3D-CTA) in pterional approach was also aimed. MATErIAL and METHods: Among 288 consecutive patients who had intracranial aneurysms detected on 64-slice CTA, a total of 337 aneurysms were detected. CTA simulation images and intraoperative images were compared with regards to size, shape, and orientation. rEsuLTs: In one of the 22 CTA-negative cases, one aneurysm was detected in DSA and an additional aneurysm was detected in a patient operated with CTA. Aneurysm size, shape and direction were error free except a few cases. However, CTA was found to be insufficient to show particularly perforating arteries that were smaller than 2 mm in size. CoNCLusIoN: As a fast and noninvasive technique, CTA can be used as an initial examination in subarachnoid hemorrhage. Keeping the fact that there can be insufficiency in showing particularly small aneurysms in mind, DSA should be performed on CTA-negative cases and required cases.

Özet

AMAÇ: Çalışmada 64 kesit bilgisayarlı tomografi (BT) ile intrakraniyal anevrizmalar tetkik edildi. Üç boyutlu simülasyon görüntüleriyle pterional yaklaşımdaki anevrizmalar karşılaştırıldı. yÖNTEM ve GErEÇLEr: Altmış dört kesit BT anjiyografi yapılan 288 hastada, 337 anevrizma saptandı. BT anjiyografideki simülasyon görüntüleriyle intraoperatif anevrizma büyüklük, şekil ve yönelimi karşılaştırıldı. BuLGuLAr: BT anjiyografi negatif olan 22 hastadan birinde dijital anjiyografide, bir olguda ise cerrahi sırasında ek anevrizma saptandı. Anevrizma boyut, şekil ve yönelim olarak çok az olgu dışında hatasızdı. BT anjiyografi 2 mm den küçük perforanları göstermede yetersiz kaldı. soNuÇ: Hızlı ve noninvaziv bir tetkik olarak BT anjiyografi ilk tetkik olarak subaraknoid kanamda kullanılabilir. Küçük damarları göstermedeki yetersizliği akılda tutularak BT anjiyografi negatif olgularda ve gerekli olgularda dijital anjiyografi yapılmalıdır.
