Abstract

Aim: Brain aneurysm is a balloon
shaped dilatation of brain vessels as a result of attenuation of the vessel
walls. The aim of this study was to evaluate the relationship between blood
flow velocities in the right and left arterial vessels in an unruptured
aneurysm and healthy group, and to investigate whether this analysis can help
early diagnosis of aneurysm.

Methods: Four aneurysm
patients (four female, mean age 57.25 ± 0.75 years) and four healthy subjects (two
female, 2 male male, mean age 36.35 ± 6.19 years) were included in the study.
Blood flow velocity values ​​of right and left internal carotid arteries,
vertebral artery and right and left internal jugular veins were obtained during
a cardiac cycle with phase contrast technique. Spearman's correlation analysis
was applied to flow velocity values. Statistically significant blood flow
similarities between right and left brain were investigated.

Results: In the aneurysm group, there
was a significant difference between right and left cervical arterial blood
flow velocity values (p=0.001). Spearman correlation coefficient values between
right and left arterial blood flow velocity values and right and left side
arteriovenous blood flow velocity values were lower in the aneurysm group
compared to the control group however, there was no statistical significance
(p≥0.05 for all).

Conclusion:  The difference between the right and left
arterial blood flow velocities obtained in the aneurysm group and the low
correlation values may be useful in early diagnosis of aneurysm.

Tek taraflı intrakranial anevrizmalı hastalarda servikal kan akış hızı değerleri: Ön sonuçlar

Abstract

Amaç: Beyin anevrizması damar
çeperlerindeki zayıflama sonucu beyin damarlarında oluşan balon şeklinde
genişlemedir. Bu araştırmanın amacı, kanamasız anevrizmalı ve sağlıklı grupta
sağ ve sol arteriyel damarlardaki kan akış hızlarını değerlendirmek ve bu
analizin anevrizma ön tanısına yardımcı olup olamayacağını araştırmaktır.

Yöntemler: Araştırmaya dört anevrizma
hastası (dört kadın, ortalama yaş 57,25 ± 0,75) ve dört sağlıklı denek  (iki kadın, iki erkek, ortalama yaş 36,35 ±
6,19) dahil edildi. Sağ ve sol iç karotis arter, vertebral arter ve sağ ve sol
iç jugular ven kan akış hızı değerleri faz kontrast tekniği ile bir kardiyak
döngü boyunca elde edildi. Spearman’ın ilişki analizi akış hızı değerlerine
uygulandı. Beyinin sağı ve solu arasındaki istatistiksel olarak anlamlı kan akış
benzerlikleri araştırıldı.

Bulgular: Anevrizma grubunda,  sağ ve sol taraf servikal arteriyel kan akış
hızı değerleri arasında anlamlı fark bulundu (p=0,001). Sağ ve sol arteriyel
kan akış hızı değerleri arasındaki ve sağ ve sol taraf arteriyovenöz kan akış
hızı değerleri arasındaki Spearman ilişki katsayı değerleri anevrizma grubunda
kontrol grubuna göre düşüktü, ancak istatistiksel anlamlılık yoktu (hepsi  için p≥0,05).

Sonuç: Bu ön araştırmanın sonuçları, anevrizma
grubunda elde edilen sağ ve sol arteriyel kan akış hızları arasındaki belirgin
farkın ve düşük ilişki değerlerinin anevrizma tanısında faydalı olabileceğini
düşündürdü.
