What artery supplies subscapularis?
Posterior circumflex humeral artery supplying the subscapularis muscle.
What does the thoracodorsal artery supply?
The thoracodorsal artery supplies predominantly the latissimus dorsi muscle but also gives branches to the serratus anterior muscle, the axillary skin, the subscapular and teres major muscles.
What does circumflex scapular artery Anastomose with?
It enters the infraspinatous fossa under cover of the Teres minor, and anastomoses with the transverse scapular artery (suprascapular) and the descending branch of the transverse cervical (a.k.a. dorsal scapular artery).
What comes off subscapular artery?
subscapular artery: the largest branch of the axillary artery, travels along the posterior wall of the axilla; distally, it divides into the thoracodorsal artery, giving branches to serratus anterior, and into the circumflex scapular artery which contributes to the scapular anastomosis; thoracodorsal artery then runs …
What artery supplies blood to the scapula?
The subscapular trunk is typically the largest branch of the axillary artery. It gives rise to the scapular circumflex artery and the thoracodorsal artery. The scapular circumflex artery runs through the triangular space and provides blood to the scapular region.
What artery travels with thoracodorsal nerve?
The thoracodorsal artery is a branch of the subscapular artery. It travels inferiorly with the thoracodorsal nerve and supplies the latissimus dorsi.
Where does the thoracodorsal artery originate?
axillary region
The thoracodorsal artery is a terminal branch of the subscapular artery that originates in the axillary region. It runs inferomedially along the lateral border of the scapula, then courses posteriorly passing deep to the latissimus dorsi muscle.
What is the clinical importance of the anastomosis around scapula?
The pectoral girdle has a rich plexus of arterial vessels that anastomose around the scapula and its muscles known as the scapular anastomosis. It functions to allow blood to flow around the scapula and shoulder joint if there is injury or occlusion.
Which arteries take part in anastomosis around scapula?
The scapular anastomosis is a system connecting certain subclavian artery and their corresponding axillary artery, forming a circulatory anastomosis around the scapula.
Where does the circumflex scapular artery begin and end?
The circumflex scapular artery stems from the posterior aspect of the subscapular artery and travels posteriorly towards the scapula. The artery curves around the lateral border of scapula and passes through the triangular space formed by the subscapularis (superiorly), teres major (inferiorly) and long head of triceps brachii (laterally).
What are the symptoms of a blocked circumflex artery?
Common symptoms associated with the blocked circumflex artery problem are: Huge pressure, tightness, heaviness or pain in the patient’s chest, particularly, at the back portion of his breastbone. Pain radiating in the neck, jaw, shoulders and arms or in the back portion Breathing shortness
Which is the larger branch of the subscapular artery?
The subscapular artery provides two large terminal branches: the circumflex scapular and thoracodorsal arteries. The circumflex scapular artery is the larger of the two terminal branches. It runs posteriorly, wraps around the lateral margin of scapula and emerges on the posterior surface of the scapula.
Can a stent be done on a circumflex artery blockage?
Can you do angioplasty stent on restively short 100% blockage in mid lad and 100 % posterolateral branch of circumflex artery & both relatively small. Generally yes: The real question is do they need to be done.
