Axillary dissection is a surgical procedure that incises the axilla, usually in order to identify, examine, or take out lymph nodes. [1] The term "axilla" refers to the armpit or underarm section of the body. [ 2 ]
If cancer is not present in the sentinel lymph nodes, then the axillary lymph node dissection should not be performed. [ 5 ] If one or two sentinel nodes have cancer that is not extensive, then no axillary dissection should be performed, but the person with cancer should have breast-conserving surgery and chemotherapy appropriate for their ...
The axillary lymph nodes or armpit lymph nodes are lymph nodes in the human armpit. Between 20 and 49 in number, they drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb.
The concept of sentinel lymph node surgery is to determine if the cancer has spread to the very first draining lymph node (called the "sentinel lymph node") or not. If the sentinel lymph node does not contain cancer, then there is a high likelihood that the cancer has not spread to any other area of the body. [2]
Mediastinal lymph nodes: They consist of several lymph node groups, especially along the trachea (5 groups), along the esophagus and between the lung and the diaphragm. In the mediastinal lymph nodes arises lymphatic ducts, which drains the lymph to the left subclavian vein (to the venous angle in the confluence of the subclavian and deep ...
Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope (see: biopsy). The lymphatic system is made up of several lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell ...
A posterior or subscapular group of six or seven glands is placed along the lower margin of the posterior wall of the axilla in the course of the subscapular artery.. The afferents of this group drain the skin and muscles of the lower part of the back of the neck and of the posterior thoracic wall; their efferents pass to the central group of axillary glands.
The substance of a lymph node is divided into the outer cortex and the inner medulla. [4] The cortex of a lymph node is the outer portion of the node, underneath the capsule and the subcapsular sinus. [17] It has an outer part and a deeper part known as the paracortex. [17]
