Objective: Cavernoma and DVA (Developmental venous anomalies) association is the most common mixed type vascular malformation. In this study, vascular and epidemiological features of DVA that may affect the development of cavernoma were investigated.

Material and Methods: Patients with cavernoma and DVA were detected by scanning the patients with contrast-enhanced brain MRI in our hospital between January 2016 and February 2019 from the database. Age, gender, location of lesions, cavernoma size, maximum number of vessels in a single section of DVA, drainage direction and drainage location of the collecting vein of these patients were determined.

Results: Of the 28 patients included in the study, 15 were female (56%) and the average age was 45 (17-82). Although supratentorial location was frequent, a statistically significant increase was observed in infratentorial ones. Subependymal drainage was present in 61% of the cases and this rate was significant in men. Cavernoma sizes were larger in GVA with top-down drainage of the collecting vein in the Z-axis.

Conclusion: The possibility of cavernoma is higher in GVA that is located infratentorially and draining into the subependymal vein, and the follow-up of patients with MRI is very important.

Amaç: Kavernom ve gelişimsel venöz anomali (GVA) birlikteliği en sık görülen miks tip vasküler malformasyondur. Bu çalışmada kavernom gelişimine etki edebilecek GVA vasküler özellikleri ve epidemiyolojik özellikler araştırılmıştır.

Gereç ve Yöntem: Ocak 2016- Şubat 2019 tarihleri arasında hastanemizde kontrastlı beyin manyetik rezonans (MR) görüntüleme yapılan hastalar veri tabanından taranarak bu görüntülerde kavernom ve GVA’sı bulunan hastalar tespit edildi. Bu hastalara ait yaş, cinsiyet, lezyonların yerleşim yeri, kavernom boyutu, GVA’nın tek kesitteki maksimum damar sayısı, toplayıcı venin drenaj yönü ve drenaj yeri belirlendi.

Bulgular: Çalışmaya dahil edilen 28 hastanın 15’i kadın (%56) olup, yaş ortalaması 45’ti (17-82). Supratentoryal yerleşim sık olmakla birlikte infratentoryal olanlarda istatistiksel olarak kavernom sayısında anlamlı artış görüldü. Subepandimal drenaj vakaların %61’inde mevcuttu ve bu oran erkeklerde anlamlı düzeydeydi. Z ekseninde toplayıcı ven drenajı yukarıdan aşağı yönde olan GVA’larda eşlik eden kavernom boyutları daha büyüktü.

Sonuç: İnfratentoryal yerleşimli, subepandimal vene drene olan GVA’larda kavernom görülme olasılığı daha yüksek olup hastaların MR ile takibi oldukça önemlidir.
