Summary: Introduction: Radiotherapy is a challenge in autologous breast reconstruction because of its impact on cutaneous and vascular systems. Hyperbaric oxygen therapy (HBOT) is a recognized treatment of radiation-related complications. We aimed to assess the impact of perioperative HBOT on irradiated breast microvascular reconstructive outcomes. Method: We reviewed the medical charts of patients who received radiotherapy and then underwent secondary free autologous breast reconstruction at our institution. Data on demographics, HBOT protocol, intervention characteristics and post-operative complications were collected. Outcomes of the irradiated patients were then compared between the HBOT and non-HBOT groups. Results: Fourteen patients were included (11 unilateral and 2 bilateral deep inferior epigastric artery perforator flaps and 1 free transverse rectus abdominis muscle flap). Seven patients received HBOT and 7 did not. In the non-HBOT group, there were 1 Clavien–Dindo grade II, 1 Clavien–Dindo grade IIIa and 2 Clavien–Dindo grade IIIb post-operative complications. In the HBOT group, there were 3 Clavien–Dindo grade I, 1 Clavien–Dindo grade IIIa and 2 Clavien–Dindo grade IIIb post-operative complications. The mean operative time was 452.3 minutes (SD ±62.4 minutes) for unilateral cases without HBOT and 457.8 minutes (SD ±102.1 minutes) with HBOT (p=0.913). Mean ischaemia time per flap without HBOT was 109.4 minutes (SD ±51.8 minutes) versus 80.1 minutes (SD ±37.7 minutes) in the HBOT group (p=0.249). Conclusion: This study provides insights into the potential of HBOT treatment in preparing patients with irradiated breast cancer for secondary autologous reconstruction.
