Supraclavicular fossa
== Supraclavicular fossa ==
The supraclavicular fossa is an anatomical feature located in the human body. It is a depression or hollow area situated above the clavicle (collarbone) and lateral to the sternocleidomastoid muscle. This fossa is clinically significant as it serves as a landmark for various medical procedures and is a site where important anatomical structures are located.
Anatomy[edit]
The supraclavicular fossa is bordered by the following structures:
- Medially by the sternocleidomastoid muscle
- Inferiorly by the clavicle
- Laterally by the trapezius muscle
Within the fossa, several important anatomical structures can be found, including:
- The subclavian artery and subclavian vein
- The brachial plexus
- The lymph nodes of the supraclavicular region
Clinical Significance[edit]
The supraclavicular fossa is of particular interest in clinical medicine for several reasons:
- **Lymphadenopathy**: Enlargement of the lymph nodes in this area can be an indicator of various diseases, including infections, lymphoma, and metastatic cancer.
- **Venous Access**: The fossa is a common site for the insertion of a central venous catheter into the subclavian vein.
- **Nerve Blocks**: The fossa is used as an access point for performing brachial plexus blocks, which are regional anesthesia techniques used in surgeries of the upper limb.
Examination[edit]
During a physical examination, the supraclavicular fossa is palpated to check for any abnormalities such as swelling, tenderness, or masses. The presence of a palpable mass in this area, known as a Virchow's node, can be a sign of gastric cancer or other malignancies.
