Pulmonary artery reconstruction with a prosthetic conduit in lung cancer.

In radical pulmonary resection for advanced lung cancer, reconstruction of the pulmonary artery (PA) can preserve the lung parenchyma. Reconstruction techniques have gained acceptance because they enable the surgeon to avoid pneumonectomy. Various techniques have been documented, such as direct suturing, end-to-end anastomosis, and a patch or conduit reconstruction. We present two lobectomy cases in which the patients underwent PA reconstruction with prosthetic conduits because they were unfit for other procedures. In both cases, the conduits showed good postoperative patency. When interposition of a conduit is required for PA reconstruction, the use of a prosthetic conduit should be considered in selected cases.
