Objective. To delineate technical aspects of vascular models with intracranial aneurysm in vitro production, suitable for angiographic imaging.
Material and methods
. Wax (K2 exact, S-U-CERAMO-CAPS-WAX), Girtl’s mass, gelatin, and silicone (Silicone 10015 Den Braven, Elastosil 7683/25, Elite Double 32 Shore-A, Rema-Sil) were used for model production. Construction of models was based on T-shaped plastic tube connections and lost core techniques. Images of rotational angiography, glass tubes with aneurysm, and casts obtained in human specimen were used as samples of cerebral arteries.
Results
. Technical aspects of vascular models production were delineated in experience of eight silicone models produced. M1 was hand made with basilar tip aneurysm; M2 was obtained according to angiography images with internal carotid artery supraclinoid part bifurcation to anterior and middle cerebral artery aneurysm. BM1 and BM2 casts were made using glass tubes with lateral aneurysm, M3 – from T-shaped plastic tubes with lateral aneurysms. M4, M5, and M6 were formed using casts obtained in human specimen with basilar tip aneurysm.
Conclusions
. Silicone of two components is practical for casts of cerebral arteries in human specimen production. Gelatinous solution 50°C diluted 1:1 with water can be used for copies of arterial casts production. Wax materials are unsuitable for making casts in a human specimen.
