The purpose of this study is to identify and compare complication rates between autologous breast reconstruction techniques with and without the inclusion on intraoperative indocyanine green (ICG) angiography.

ICG-angiography is a real-time visualization of tissue perfusion using intravenous fluorescence. It allows the surgeon a tool for intraoperatively assessment of tissue perfusion of the autologous flap, providing a basis for trimming of hypo perfused areas. The study evaluates the effect of inclusion of this technique by examine postoperative outcomes retrospectively. This is done by differentiation between major and minor complications to evaluate the greatest gains of the intervention.

Inclusion Criteria:

• Eligible patients over the age of 18 years
• Deemed suitable for breast reconstruction with the latissimus dorsi (LD) myocutaneous flap, muscle sparring LD flap or transverse rectus abdominal muscle (TRAM) flap

Exclusion Criteria:

• Patients with recurrence of breast cancer
• Smoking 4 weeks prior of operation
• Not able to read and understand Danish

Patients who underwent immediate or delayed, pedicle autologous flap breast reconstruction between 2012 and 2016 were enrolled in the study.
