However, anatomical understanding is unclear, due to limited cadaver and clinical studies. We evaluated the usability of these vessels by evaluating perforator size, dominance, laterality, interspace location, and relationship with breast volume.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective review assessed 197 female patients with breast cancer who had undergone computed tomography angiography (CTA) of the chest wall.

Most patients (95.5%) had sizeable perforating artery identified on CTA. Among all sizeable perforators identified, the mean diameter of the most dominant arterial perforator was 1.8\u2009\u00b1\u20090 .8\u2009mm. The right hemi\u2010chest had significantly larger perforators than the left (1.9\u2009\u00b1\u20090 .9\u2009mm vs. 1.7\u2009\u00b1\u20090 .7\u2009mm, <jats:italic>p<\/jats:italic>\u2009=\u20090.002). The first intercostal space (ICS) had a slightly greater of perforators than second ICS (34.6% vs. 29.8%, <jats:italic>p<\/jats:italic>\u2009=\u20090.172). However, second ICS had a greater number of most dominant perforators compared to first ICS (38.9% vs. 34.7%, <jats:italic>p<\/jats:italic>\u2009=\u20090.357). Perforators from first ICS emerge medial to the sternal edge and breast footprint. When dividing groups with 0\u20131 versus 2\u20133 reliable perforators, breast volume was significantly higher in the later (422.0\u2009mL vs. 461.2\u2009mL,
