How is pectoralis minor syndrome treated?

What is pectoralis minor?
Together the pectoralis minor and minor, as well as their associated fascia, form the anterior wall of the axilla. Posteriorly the pectoralis minor is related to the serratus anterior and intercostal muscles, the ribs and several neurovascular and lymphatic structures, described below.
What is a PECS I block?
It is an alternative to paravertebral blocks in patients receiving breast surgery. The PECS I block targets the pectoral nerves, which arise from the brachial plexus cords. The lateral pectoral nerve arises from C5-7, runs between the pectoralis major and minor muscles, and supplies innervation to the pectoralis major muscle.
What is a PECS II block in breast surgery?
The PECS II block is used when patients are receiving more extensive breast surgery such as tumor resection and mastectomy, involving the pectoralis major and minor muscles, the serratus anterior muscle, and the axilla.
What nerve does the Pecs I block?
The PECS I block targets the pectoral nerves, which arise from the brachial plexus cords. The lateral pectoral nerve arises from C5-7, runs between the pectoralis major and minor muscles, and supplies innervation to the pectoralis major muscle.
