Q

To cut off all blood flow to the arm, ligation must occur at what location?

A

Distal to Subscapular A.

Ligation of the Axillary A. reverses blood flow in the Subscapular A. due to collateral circulation arriving via Suprascapular A., Transverse Cervical, and Intercostal A. to the scapular region and continuing feeding blood to the Brachial A.
