Amaç: Hidrosefalinin tanısı hala ciddi bir sorundur. Cerrahi tedaviye karar vermeden önce tanıyı doğrulamak önemlidir. Literatürde tanımlanmış kriterler bazı vakalarda hidrosefali tanısı için yeterli gözükmemektedir. Biz hidrosefalinin BOS/parankim dansitesi üzerine etkilerini araştırdık ve tedavi edilmiş ve tedavi edilmemiş hidrosefali hastalarında bu dansitelerdeki değişiklikleri göstererek bir fikir vermeyi amaçladık.

Materyal ve metodlar: Biz dansite ölçümleri için bilgisayarlı tomografi (BT) ile Hounsfield ünitesini (HU) kullandık. Bu retrospektif çalışmada iki çalışma grubunu inceledik. Hidrosefali tanısını almış ve ventriküloperitoneal şant cerrahisi tedavisi uygulanmış 20 hasta operasyon grubunu oluşturdu. Bu gruptaki hastalar operasyon öncesi ve sonrası BT ile ayrı ayrı değerlendirildi. Bu nedenle bu gruptaki hastalar aynı zamanda preoperatif ve postoperatif çalışma gruplarını oluşturdular. Serebral patoloji saptanmamış tomografiye sahip 20 hasta da kontrol grubunu oluşturdu. Serebral dansite ölçümlerini klinik BT kullanarak HU ile yaptık. Çalışma gruplarının HU değerleri birbirleri ile istatistiksel analiz kullanılarak karşılaştırıldı.

Bulgular: Ventriküllerin frontal ve oksipital hornlarından alınan HU değerleri operasyon sonrası uyumlu bir şekilde azaldı. İncelenen ventriküllerde, preoperatif HU değerleri ile postoperatif HU değerleri arasında istatistiksel olarak ileri derecede fark bulundu. Ayrıca gri cevher komşuluğundaki beyaz cevher HU değerlerinde operasyon sonrası istatistiksel olarak çok belirgin azalmalar tespit edildi.

Sonuç: BT ile dansite ölçümü hidrosefali tanısına kolaylıkla yardımcı olabilir.

 

ABSTRACT

 

Objectives: Diagnosis of hydrocephalus is still challenging. It is important to confirm the diagnosis before deciding surgical treatment. Defined criteria in the literature seems insufficient for the diagnosis of hydrocephalus in some cases. We aimed to analyze the effects of hydrocephalus to CSF/parenchymal density and give an understanding about the changes in CSF/parenchymal density in non-treated and treated hydrocephalus patients.

Materials and methods: We used computed tomography (CT) with Hounsfield unit (HU) for density measurements. Two study groups were evaluated in this retrospective study. Twenty patients who had diagnosis of hydrocephalus and underwent ventriculoperitoneal shunt surgery, were included in the operation group. These patients were evaluated both preoperatively and postoperatively with CT. Therefore, this group also was divided into preoperative and postoperative study groups. Twenty patients who had brain CT with no detected cerebral pathology were included in the control study group. Cerebral density measurements were obtained from clinical CT with HU. HU values of the study groups were compared with each other by using statistical analysis.

Results: The HU values of the ventricules in the frontal and occipital horns consistently decreased after the operations. There were extremely significant differences between the preoperative HU values and the postoperative HU values of the all evaluated ventricles statistically. Additionally, there were very significant decreases after the operations in the HU values of white matter near grey mater.

Conclusıon: Density measurements with CT can easily make contribution in the diagnosis of hydrocephalus.
