Final answer:
The described procedure is a specific method used in embalming to control the distribution of preservative fluids. The term for this method is not provided in the reference materials. The common carotid artery, involved in this process, supplies blood to the head and neck.
Step-by-step explanation:
The term for the embalming process indicated is not directly provided in the supplied information. However, the question describes a method where one of the carotid arteries is injected while the other is occluded. This process is generally known in embalming practice to precisely control the flow of embalming fluid. In the broader context of medical procedures, embalming is not typically discussed alongside treatments like angioplasty, which is a treatment for occluded arteries noted in the passage. Instead, embalming is a process performed post-mortem to preserve and sanitize the body.
For the supplied references on arteries, it is essential to recognize that the common carotid artery plays a critical role in supplying blood to the head and neck, splitting into the external and internal carotid arteries. While the embalming process typically involves such arteries for the injection of preservative fluids, the procedure described in the question seems specific to the embalming field and does not have a name provided in the reference passages. It is a technique aimed at targeting the distribution of fluids in a controlled manner.
