Three-dimensional virtual simulation of cervical deep vein puncturation / 中国组织工程研究

ABSTRACT

BACKGROUND:Three-dimensional visual model of cervical deep vein can be used to virtual simulation of puncture. The studies on elevating deep vein puncture in the clinic are stil in the stage of exploration. OBJECTIVE:To find the application of three-dimensional virtual puncturation simulation to cervical deep vein puncturation. METHODS:CT cross-sectional images were obtained from healthy volunteers. Mimics software was used to semi-automatical y cut and reconstruct of various tissue of the neck. Three-dimensional model revealed cervical deep veins and its surrounding anatomic structure. Cervical deep vein puncturation was simulated, including internal jugular vein, supraclavicular vein and subclavian vein. RESULTS AND CONCLUSION:Three kinds of cervical deep vein puncturation were successful y simulated, showing three-dimensional adjacent relation of the virtual pin with surrounding anatomic structure. Safe angle, depth and optimal path of the pin were measured. A three-dimensional virtual puncturation simulation can provide visualized morphologic data for cervical deep vein puncturation.
