Multidetector computed tomography angiography to evaluate the subscapular arterial tree

Area of Science:

• Anatomy
• Radiology
• Vascular Surgery

Background:

• The subscapular artery is crucial for reconstructive surgery, supplying major pedicles for various flaps.
• Understanding its anatomy and variations is essential for successful surgical outcomes.

Purpose of the Study:

• To provide detailed anatomical data of the subscapular artery and its branches using MDCTA.
• To evaluate the clinical utility of MDCTA in preoperative planning for reconstructive surgery.

Main Methods:

• A retrospective analysis of thoracic MDCTA scans from 92 patients was performed.
• Bilateral subscapular arteries and branches >0.5 mm in diameter were evaluated for diameter and length.

Main Results:

• Mean diameters of the subscapular, circumflex scapular, and thoracodorsal artery origins were measured.
• Mean lengths of the circumflex scapular artery and branches of the thoracodorsal artery were recorded.
• Variations such as doubled circumflex scapular arteries (4.3%) and direct branching from the axillary artery (3.2%) were identified. No significant sex or side differences were noted.

Conclusions:

• MDCTA is a highly effective non-invasive tool for detailed vascular anatomy assessment.
• It aids in identifying anatomical variations, crucial for enhancing surgical safety in reconstructive procedures.
