Abstract

Introduction and purpose: Aneurysms
affect the hemodynamics and perfusion of the brain, with complications such as
intra-parenchymal mass, ruptured bleeding, and vascular spasm. For this reason,
the purpose of the treatment is to remove an aneurysm completely from the
circulation, to eliminate the possibility of bleeding, to destroy the mass
effect, and to protect the blood flow in the main artery. Our study aims to
determine how aneurysm treatment affects brain perfusion.

 Materials
and Methods:
Between 2014 and 2017, 42 patients who underwent endovascular
aneurysm treatment at Atatürk University’s Radiology Department were examined.
Eight patients were excluded from the study because they did not meet the
inclusion criteria. The data for 34 patients were evaluated in the study. Brain
perfusion parameters were measured before the procedure, 3 days after the
procedure, and 1 month after the procedure. Also, rCBV, rCBF, MTT, and TTP
parameters were compared with posterior circulation, and the changes in
perfusion parameters were evaluated statistically.

Results: The
size of the aneurysm was measured as ≤ 10 mm in our patients. Thus these
patients were evaluated as part of the small aneurysm class. When the perfusion
parameters were compared, there was no significant difference between
preoperative and postoperative values in terms of rCBV, rCBF, and MTT. The p
values obtained were as follows: for rCBV, p = 0.652; for rCBF, p = 0.563; and
for MTT; p = 0.865. There was a significant difference in the values obtained
from the TTP map (p = 0.025). According to the measurements taken before the
operation, prolongation was observed on the third day after the operation,
which decreased in the first month after the operation.







Conclusion: Because
small aneurysms do not affect rCBV and rCBF during brain perfusion,
perfusion-related complications (hyperperfusion syndrome), which can be seen
during the treatment of aneurysms, are not expected. The third-day prolongation
and the shortening of the first month of the TTP period may be indicative of
complications such as brain edema and vasospasm, which may develop during or
after the procedure

Abstract

Giriş ve Amaç:
Anevrizmalar kese içi doluma bağlı kitle etkisiyle veya rüptürüne bağlı kanama
ve vasküler spazm gibi komplikasyonlarla beyin hemodinamiğini ve perfüzyonunu
etkiler. Bu nedenle, tedavideki amaç anevrizmayı tam olarak dolaşım dışında
bırakarak kanama ihtimalinin ortadan kaldırılması, kitle etkisinin yok edilmesi
ve bunun yanı sıra ana arterdeki kan akımının korunmasıdır. Çalışmamızdaki
amacımız anevrizmaların tedavisi ile beyin perfüzyonu üzerinde yaptığı
değişimlerin belirlenmesidir.



Gereç ve Yöntem:
2014 - 2017 tarihleri arasında Atatürk Üniversite Radyoloji A.B.D.’da
endovasküler anevrizma tedavisi yapılan 42 hasta incelemeye alındı. 8 hasta
değerlendirme kriterlerine uymadığı için çalışmadan çıkarıldı. Çalışmada
yaşları 21-69 arasında değişen (ort:52) 34 hastada işlem öncesi, işlem sonrası
3.gün ve işlem sonrası 1. ay beyin perfüzyon parametreleri (rCBV, rCBF, MTT ve
TTP) , posterior dolaşımla kıyaslanarak perfüzyon parametrelerinde ki
değişimler istatistiksel olarak değerlendirildi.



Bulgular:
Çalışma popülasyonumuzun ortalama yaşı 52 yaştır (21-69). Hastalarımızda
anevrizma boyutu ≤ 10mm ölçülmüş olup küçük anevrizmalar sınıfında
değerlendirildi. Operasyon öncesi, operasyon sonrası üçüncü gün ve operasyon
sonrası birinci aya ait perfüzyon parametreleri karşılaştırıldığında rCBV, rCBF
ve MTT değerleri bakımından operasyon öncesi ve sonrasında istatistiksel olarak
anlamlı farklılık saptanmamıştır. İstatistiksel p değerleri: rCBV için; p=0,652
, rCBF için; p=0,563 , MTT için; p=0,865 bulunmuştur. TTP haritasından elde
edilen değerlerde ise operasyon öncesine göre, operasyon sonrası üçüncü gün
uzama ve operasyon sonrası birinci ayda ise azalma izlenmiş olup anlamlı farklılık
tespit edilmiştir ( p=0,025 ).



Sonuç: Küçük anevrizmalar beyin perfüzyonunda rCBV ve
rCBF’ ye etki etmediğinden bu anevrizmaların tedavisinde perfüzyona bağlı
komplikasyonlar (hiperperfüzyon sendromu) beklenmemektedir. TTP haritasının
3.gün uzaması ve 1. ay kısalması işlem sırasında ve sonrasında gelişen beyin
ödemi, vazospazm gibi komplikasyonları açısından gösterge olabilir.
