The vascular territories of the anterior chest wall
Insights
This study details the vascular network of the anterior chest wall, highlighting the internal thoracic artery as the primary blood supplier. Findings are crucial for surgical planning in breast reduction and flap procedures.
Area of Science:
- Anatomy
- Vascular Surgery
Background:
- Understanding the vascular supply of the anterior chest wall is critical for surgical procedures.
- Previous studies have provided foundational knowledge, but detailed correlations are needed.
Purpose of the Study:
- To define the vascular architecture of the anterior chest wall.
- To correlate new findings with existing literature.
- To assess the clinical significance for surgical applications.
Main Methods:
- Conducted 31 fresh cadaver studies.
- Utilized injection, dissection, and radiographic techniques.
Main Results:
- Confirmed the internal thoracic artery as the dominant blood supply.
- Identified interconnectivity with posterior intercostals, lateral thoracic, acromio-thoracic, and transverse cervical arteries.
- Located dominant cutaneous perforators around the pectoralis major, costal margin, and serratus anterior.
Conclusions:
- The vascular patterns are key for designing breast reduction techniques.
- Specific perforator concentrations along the inframammary crease originate from anterior intercostal vessels.
Abstract:
A series of 31 fresh cadaver injection, dissection and radiographic studies were undertaken to define the vascular architecture of the anterior chest wall and to correlate the findings of previous writers in this area. The findings confirmed that the dominant supply to this region is from the internal thoracic artery which interconnects in all layers with the posterior intercostals, the lateral thoracic, the acromio-thoracic and the transverse cervical arteries. The dominant cutaneous perforators of these vessels are concentrated around the perimeter of the pectoralis major muscle, the costal margin and over the interdigitations of the serratus anterior muscle in the mid-axillary line. The clinical significance of these findings is discussed with particular reference to the design of various breast reduction procedures and the planning of flaps in this area. Of special note is the observation that the concentration of large perforators which exists along the inframammary crease arises from the anterior intercostal vessels in the fifth and sixth intercostal spaces.
