Pulmonary artery reconstruction using cryopreserved allograft for lung cancer: a bi-centric comparative study.

ABSTRACT:

Background

Pulmonary artery (PA) reconstruction during lung cancer surgery is a recognized parenchymal-sparing alternative to pneumonectomy. However, the use of cryopreserved allografts for PA reconstruction remains limited. This study aims to evaluate the surgical morbidity and mid-term performances of three different PA reconstruction techniques, including cryopreserved grafting, direct suture and end-to-end anastomosis, in lung cancer surgery.

Methods

We retrospectively analyzed all patients who underwent PA reconstruction following lung lobectomy with en-bloc vascular resection over a 20-year period in two tertiary lung surgery centers. The patients were assigned to three groups: patch closure of the PA (group 1, n=60), end-to-end anastomosis (group 2, n=24), and cryopre
