The posterior circumflex humeral artery
was accompanied by the axillary nerve and they entered the quadrangular space.
* Common trunk of subscapular and circumflex humeral artery
, which further divides into anterior and posterior cirumflex humeral arteries are rarely reported in the literatures.
Posterior circumflex humeral artery
injury with distal embolisation in professional volleyball players: a discussion of three cases.
In up to 30% of the cases, the subscapular artery can arise from a common trunk with the posterior circumflex humeral artery
. Occasionally, the subscapular, anterior circumflex humeral, posterior circumflex humeral and profunda brachii arteries arise in common.
The fibromuscular slip between the Brachialis and Brachioradialis forms a fibromuscular tunnel underneath which lies the Radial nerve along with descending branch of posterior circumflex humeral artery
. No mention of this vascular relationship was found in available literature.
* The three terminal branches of the collateral artery are posterior circumflex humeral artery
, circumflex scapular artery and thoracodorsal arteries.
In up to 30% of cases, the subscapular artery can arise from a common trunk with the posterior circumflex humeral artery
. Occasionally the subscapular, circumflex humeral and profunda brachii arteries arise in common, in which case, branches of the brachial plexus surround this common vessel instead of axillary artery.
