What is Axillary Lymph Node Dissection?

Axillary lymph node dissection is part of various cancer operations, especially those involved in removal of the breast. This is a necessary operation because breast cancers frequently involve the axillary lymph nodes.

What does Axillary Lymph Node Dissection involve?

A complete axillary lymph node dissection involves risk and exposure to many important nearby structures. In addition, most of these operations will affect some or all of the following:

• Pectoralis major and minor muscles together with their nerve supply.

• Axillary tail of the breast.

• Axillary thoraco-acromial vessels.

• Affected tributaries of the axillary vein.

• Many smaller branches of the axillary artery.

What is Preserved in Axillary Lymph Node Dissection?

Every effort is made to preserve the following:

• Brachial plexus.

• Axillary vein and artery.

• Thoraco-dorsal nerve (to latissimus dorsi muscle).

• Long thoracic nerve (to serratus anterior muscle).
