33. Anastomosis Around Scapula
34. First part of Subclavian a. Third part of Axillary a. Suprascapular a. Subscapular a. Circumflex scapular a. Deep branch of transverse cirvical a. Lateral cutaneous branches of posterior intercostal arteries from Thyrocervical trunk Thoracic aorta Dr.Sherif Fahmy
35. Descending thoracic Aorta Dr. Sherif Fahmy
36. Anastomosis Around Scapula It is the anastomosis between first part of subclavian, third part of axillary and abdominal aorta through the following branches: Site: the dorsal aspect of scapula. A- First part of subclavian artery: 1- Suprascapular a. (supraspinous & infraspinous fossae) 2- Deep branch of transverse cervical artery (supraspinous & infraspinous fossae). B- Third part of axillary artery: 1- Circumflex scapular artery from subscapular artery (infraspinous fossa). C- Descending thoracic aorta: 1- Anterior divisions of lateral cutaneous branches of posterior intercostal arteries (supraspinous & infraspinous fossae).
37. Importance of Anastomosis Around Scapula 1- Bypassing block in the artery between subclavian and 3rd part of axillary artery. 2- In aortic coarctation, it allow flow of blood to lower ½ of the body.
