| Popis: | The aim of the study was to investigate the relationship of BMI and abdominal wall thickness (AWT) with the diameter of the dominant deep inferior epigastric artery perforator (DIEP) as well as DIEA branching pattern in preoperatively performed computed tomography angiography (CTA).We conducted a retrospective study including all patients undergoing DIEP flap breast reconstruction with available CTAs from November 2013 to April 2018 in our department. The caliber-strongest DIEP was detected after passage of the rectus fascia as well as the superficial inferior epigastric artery (SIEA) and correlated with the AWT 5 cm above and below the umbilicus, lateral at the level of the umbilicus and at the level of the anterior superior iliac spine (ASIS), and with BMI.Seventy-seven patients met the inclusion criteria (age: 47.3 ± 8.9 years). We observed a significant relationship (p 0.05) between DIEP (mean ∅ = 2.98 mm) and BMI (r = 0.353), the AWT supra- and infraumbilical (r ≥ 0.32), and the AWT lateral at the level of the umbilicus and ASIS (r ≥ 0.25). In addition, there was a highly significant correlation (p 0.01) between SIEA and BMI (r = 0.389) and between the AWT lateral at the level of ASIS (r ≥ 0.41).We demonstrated a correlation of the diameter of the dominant DIEP with both BMI and AWT. Focusing on the diameter, in patients with a high AWT at the level of the ASIS, the SIEA, if present, may represent an alternative therapeutic option. |
