Vascular Anatomy of the Subacromial Space: A Map of
Bleeding Points for the Arthroscopic Surgeon
Purpose: Our purpose was to study the vascular anatomy of the subacromial
space and to map the major sources of expected bleeding during
subacromial arthroscopy surgery. Methods: Ten shoulders of five adult
cadavers underwent whole-body arterial perfusion with a mixture of lead
oxide, gelatin, and water. The tissue specimens were dissected,
photographed, radiographed, scanned, and analyzed with a digital software
analyzer. Dissection of the arteries of the subacromial space, with their
respective anatomic landmarks, was documented. Correlations of bleeding
areas during subacromial arthroscopic surgery and cadaveric dissection were
carried out. A vascular map of the walls of the subacromial space was
created. Results: The vascularity of the subacromial structures showed
consistent patterns of distribution in 60% of the shoulders dissected, and
specific sources of bleeding were analyzed. We divided this space into walls
with their major arteries as follows: anterior wall, with the acromial branch of
the thoracoacromial artery; posterior wall, with the posteromedial acromial
branch of the suprascapular artery; and medial wall, with the anterior and
posterior arteries of the acromioclavicular joint. The vascular map of the
lateral wall, roof, and floor of the subacromial space was also described.
Conclusions: Vascular maps of the arteries of the walls of the subacromial
space were created. The subacromial space is highly vascular, and the
pattern of blood supply was found to be constant in 60% of the shoulders
dissected. This knowledge of the vascular anatomy may decrease bleeding
during surgery. Clinical Relevance: Knowledge of the vascular anatomy may
decrease vascular damage during subacromial arthroscopy surgery
