TETRATHECAL Meaning and Definition

1. Tetrathecal is a term used in the field of medicine to describe a process or procedure that involves the introduction of substances into or around the fourth ventricle of the brain. It refers to the administration of medication directly into this specific region, which is located in the lower part of the brainstem.

   The fourth ventricle is one of the interconnected cavities within the brain that contains cerebrospinal fluid (CSF), which surrounds and protects the brain and spinal cord. Tetrathecal administration can involve injecting therapeutic agents, such as medications or contrast agents, into this fluid-filled space for various diagnostic or therapeutic purposes.

   This procedure may be utilized in the treatment of certain medical conditions, such as chronic pain management, cancer-related symptoms, or central nervous system infections. It can allow for targeted drug delivery, bypassing some barriers that may impede access to the brain or spinal cord. Tetrathecal administration may also help reduce systemic side effects that can occur with other routes of drug delivery.

   This term is derived from the Greek word "tetra" meaning "four" and "theca" meaning "case" or "container," referring to the fourth ventricle as the specific anatomical location where the substances are introduced. It is important to note that the administration of drugs through this method is a specialized procedure that requires professional training and expertise to ensure safety and efficacy.

2. In bot., having four loculaments or thecae.
