An innovative method in venous coronary cast technique.

Area of Science:

• Anatomical studies
• Material science

Background:

• Polyurethane foam (PU foam) is increasingly used for creating anatomical specimens.
• Conventional injection techniques face challenges with certain anatomical structures like the coronary sinus.

Purpose of the Study:

• To evaluate the morphology of the coronary sinus and its tributaries.
• To address difficulties encountered during injection and maceration for specimen preparation.

Main Methods:

• Development of a novel device for cannulating the coronary sinus orifice.
• Adaptation of maceration techniques to manage saponified adipose tissue.

Main Results:

• The new device facilitates the injection of casting media into the coronary sinus.
• Modified maceration effectively handled saponified adipose tissue, enabling clearer specimen visualization.

Conclusions:

• The developed device and modified maceration technique improve the preparation of coronary sinus anatomical specimens.
• This approach enhances the utility of PU foam in creating detailed macro- and micro-anatomical samples.
