This study evaluates results of Indocyanine Green Videoangiography (ICG-VA) in a patient group with intracerebral aneurysms. To assess reliability of this technique, ICG-VA findings were compared with postoperative cerebral angiography. Furthermore, benefits and limitations of this intraoperative evaluation method were discussed. This study includes 75 aneurysms in 61 consecutive patients. Following clip ligation of the aneurysm, ICG was administrated intravenously to observe the aneurysm, parent arteries, and perforating arteries. All patients under-went postoperative angiography before discharge. In 86.6% of aneurysms, ICG-VA confirmed satisfactory clip application and was concor-dant with postoperative angiography. In 6.6% of aneurysms, ICG-VA showed pathological findings intraoperatively leading to readjustment of clips immediately. In another 6.6% of aneurysms, ICG-VA did not reveal any pathological findings intraoperatively while postoperative angiography was not normal in these cases. ICG-VA cannot replace the intraoperative angiography yet as the gold standard method of int-raoperative blood assessment. However, this technique adds greatly to the safety of the surgical treatment of intracranial aneurysms. ICG-VA promoted real time assessment of the surgical field with good image quality. It is easy to perform and evaluate the procedure. This technique has the potential to be considered as a standard step of this surgical intervention.

Beyin Anevrizmalarının Cerrahi Tedavisinde Indocyanine Green Videoanjiyografi Kullanımı

Öz

Bu çalışmada, beyin anevrizması nedeniyle cerrahi tedavi uygulanan bir hasta grubunda İndosiyanin Yeşili Videoanjiyografi (ICG-VA) yönteminin sonuçlarının değerlendirilmesi amaçlanmıştır. Bu intraoperatif değerlendirme yönteminin güvenilirliğini saptamak için, ICG-VA bulguları postoperative anjiyografi ile karşılaştırılmıştır ve bu yöntemin faydaları ve kısıtlılıkları tartışılmıştır. Bu çalışmaya, 75 anevrizma saptanan altmış bir ardışık hasta dahil edilmiştir. Anevrizmanın kliplenmesini takiben; anevrizmayı, ana arterleri ve perforan arterleri göz-lemlemek için intravenöz yoldan ICG uygulandı. Ameliyat sonrasında tüm hastalara taburculuk öncesi anjiyografi yapıldı. Anevrizmala-rın %86,6'sında, ICG-VA tatmin edici klipleme sağlandığını gösterdi ve ICG-VA bulguları postoperatif anjiyografi ile uyumluydu. Anevriz-maların %6.6'sında, anormal ICG-VA bulguları saptandı ve kliplerin değiştirilmesi veya düzeltilmesi gerekli oldu. Anevrizmaların bir di-ğer % 6.6'sında ise, ICG-VA herhangi bir patolojik bulgu göstermezken postoperatif anjiyografide anormal bulgular saptandı. ICG-VA ameliyat esnasında kan akımının değerlendirmesinde altın standart yöntem olan intraoperatif anjiyografinin yerini almamakla birlikte, beyin anevrizmalarının cerrahi tedavisinde hasta güvenliğine büyük katkıda bulunmaktadır. ICG-VA, iyi görüntü kalitesiyle cerrahi alanın gerçek zamanlı değerlendirilmesini mümkün kılmaktadır. İşlemi gerçekleştirmek ve değerlendirmek kolaydır. Bu teknik, anevrizma cerrahisinin standart bir uygulaması olarak değerlendirilmelidir.
