Introduction Omental flap (OF) is a traditional surgical option to counteract severe postcardiotomy mediastinal infection and to cover extensive sternal defects. We reviewed our experience with omental flap transfer (OFT) in various clinical circumstances, in which omentoplasty may be considered by cardiac surgeons.

Methods Twenty-one patients, who underwent OFT from January 2012 to December 2021, were studied. The main indication was treatment of infected foreign material implants including vascular grafts and ventricular assist devices or prevention of its infection (16 patients). In five patients, an OFT was used to cure mediastinitis following deep sternal wound infection after median sternotomy.

Results All patients had a high surgical risk with 3 ± 1.9 previous sternotomies and a mean Euro Score II of 55.0 ± 20.1. OF was successful in its prophylactic or therapeutic purpose in all patients, no complications related to the operative procedure were noted, that is, no early or late flap failure and no herniation of abdominal organs occurred. In-hospital mortality was six patients as three patients each died from multiple organ dysfunction syndrome and cerebral hemorrhage. All fifteen patients discharged demonstrated rapid recovery, complete wound healing without fistula, and no late gastrointestinal complications. The mean follow-up of 18 months was uneventful.

Conclusion OFT seems to be an excellent solution for extensive mediastinal and deep sternal wound infections.

网膜 瓣 (OF) 是一种传统的手术选择，用于抵消严重的心脏切开术后纵隔感染并覆盖广泛的胸骨缺损。我们回顾了我们在各种临床情况下进行大网膜瓣转移 (OFT) 的经验，在这些情况下，心脏外科医生可能会考虑进行大网膜成形术。

方法 对 2012 年 1 月至 2021 年 12 月接受 OFT 的 21 名患者进行了研究。主要适应症是治疗感染的异物植入物，包括血管移植物和心室辅助装置或预防其感染（16 名患者）。在 5 名患者中，OFT 用于治疗正中胸骨切开术后深部胸骨伤口感染后的纵隔炎。

结果 所有患者的手术风险都很高，之前有 3 ± 1.9 次胸骨切开术，平均 Euro Score II 为 55.0 ± 20.1。OF 在所有患者中的预防或治疗目的都是成功的，没有发现与手术过程相关的并发症，即没有早期或晚期皮瓣失败，也没有发生腹部器官疝出。院内死亡率为 6 名患者，其中 3 名患者分别死于多器官功能障碍综合征和脑出血。所有出院的 15 名患者都表现出恢复迅速，伤口完全愈合，无瘘管，无晚期胃肠道并发症。平均 18 个月的随访是平安无事的。

结论 OFT 似乎是广泛纵隔和深部胸骨伤口感染的极佳解决方案。
