Application of preoperative embolization during surgery for the destroyed lung

The destroyed lung has been a challenge in the clinical practice of thoracic surgery, and severe adhesions and massive bleeding during surgery are the main obstacles faced by surgeons. This study aimed to investigate the efficacy of the preoperative embolization of blood vessels in adhesions during surgery for the destroyed lung.

A total of 7 patients underwent preoperative embolization for lung resection of destroyed lungs between June 2016 and February 2019. Preoperative embolization was performed for 45 min to 2 h within 48 h before surgery. The embolized arteries included the intercostal artery, radial artery, subclavian artery and their branches, and the number of embolized arteries ranged from 5 to 13.

A posterolateral incision was made in these patients, and endoscope-assisted separation of the adhesions at the top of the chest wall and on the lateral chest wall was performed. The operation time ranged from 3.5 to 8 h, and the blood loss was 1,200-5,000 mL. The postoperative drainage was in the normal range. One patient developed multiple organ failure and bronchopleural fistulas (BPF) one month after surgery, which was resolved after active drainage and argon cauterization; another patient developed BPF 7 months after surgery, which was resolved after placement of a nonreturn valve in the subsegmental bronchi via bronchoscopy.

Surgery of the destroyed lung is a great challenge in clinical practice, mainly due to the risk of the blood supply in the adhesions. Preoperative embolization may reduce intraoperative blood loss and surgical difficulty.
