Clinical Decision Making Using CTA in Conjoined, Bipedicled DIEP and SIEA for Unilateral Breast Reconstruction.

 Guided by preoperative CTA imaging, we recommend the consistent use of these conjoined, bipedicled hemi-abdominal flaps for unilateral breast reconstruction, primarily those with delayed reconstruction and radiation deficits. Preoperative CTA imaging is crucial in directing perforator dissection to maximize overlapping perfusion zones and guide in performing anastomoses.
