Technique of colored latex vascular injection in neurosurgical soft cadaveric head.

ABSTRACT

Objective: To present our technique of injected vascular specimen, so as to facilitate the process of cadaveric head preparation.Material and Method: Colored latex is used to inject the extracranial part of cerebral arteries and veins. The process is composed of three steps and can be summarized as follows 1) exposure and cannulation of the extracranial vessels 2) irrigation of vessels to remove blood clol and 3) preparation and injection of the colored latex. Results: The quality of the injection was evaluated by inspection of both superficial and deep vascular trees( both venous and arterial dural vessels). There was sometimes the leakage of latex from the vessels. Conclusion: The simple and inexpensive process of cadaveric head preparation would promote the neuroanatomical knowledges of neurosurgical residents and practicing neurosurgeons.
