Abstract

Aim: Topical hemostatic agents are widely used in brain surgery but they have some disadvantages such as foreign body reaction, being a focus for infection and causing artifacts in radiological examinations. The purpose of this study is to compare the effectiveness and safety of microporous polysaccharide hemospheres (MPH) with a well known agent, oxidized regenerated cellulose (ORC), histopathologically and radiologically. Material and Methods: Standard brain lesions (4x1mm) were created in 24 hemispheres in 12 New-Zealand rabbits. Animals were divided into three groups; control, ORC and MPH. Twenty-four hours later, all rabbits magnetic resonance brain imaging. After imaging, the animals were sacrificed and the brains were removed for histopathological analysis. Results: Histopathological analysis showed no significant difference between the groups. Radiological examination showed no significant difference between the MPH and ORC groups in terms of edema but the edema in control group was significantly prominent than MPH and ORC groups (p<0.001). Conclusion: A new agent (MPH) provides safe and effective hemostasis in the brain in this study. The most important advantage of microporous polysaccharide hemospheres is their rapid clearance from the surgical field and therefore having the potential of causing less imaging artifacts.

Özet

Amaç: Topikal hemostatik ajanlar beyin cerrahisinde yaygın bir şekilde kullanılmakla birlikte yabancı cisim reaksiyonu, enfeksiyon için odak oluşturma ve radyolojik tetkiklerde artefakt oluşturma gibi dezavantajları mevcuttur. Bu çalışmanın amacı, mikroporöz polisakkarit hemosferler (MPH) ile iyi bilinen bir ajan olan okside rejenere sellülozun (ORC) etkinlik ve güvenilirliklerini histopatolojik ve radyolojik olarak karşılaştırmaktır. Yöntem ve Gereç: 12 Yeni Zelanda tavşanında 24 hemisferde standart (4x1 mm) beyin lezyonları oluşturuldu. Denekler 3 gruba ayrıldı; kontrol, ORC ve MPH. Yirmi dört saat sonra tüm hayvanlara manyetik rezonans görüntüleme yapıldı. Görüntüleme sonrası denekler sakrifiye edildi ve beyinleri histopatolojik analiz için çıkarıldı. Bulgular: Histopatolojik analiz gruplar arasında belirgin farklılık göstermedi. Radyolojik incelemede ödem yönünden MPH ve ORC grupları arasında belirgin farklılık izlenmemekle birlikte, kontrol grubunda ödem MPH ve ORC gruplarına gore belirgin bir şekilde yüksek bulundu (p<0,001). Sonuç: Bu çalışmada yeni bir ajan (MPH), beyinde hemostazda güvenilir ve etkin bulunmuştur. MPH'ın en önemli avantajı cerrahi sahadan hızla uzaklaşması ve bu yolla daha az potansiyel görüntüleme artefaktına yol açmasıdır.
