    Abstract:
    Lung cancer may involve the pulmonary artery (PA) either by direct extension of the primary tumor or by invasion of the hilar lymph nodes. In these instances, a radical resection is usually a pneumonectomy despite distal functioning lung tissue. To spare the lung parenchyma, angioplastic procedures requiring removal of a portion of the arterial wall or a circumferential resection with arterial reconstruction have been used. Several techniques of pulmonary arterioplasty have been explored suggesting that the incidence of postoperative complications is acceptably low and long-term local control can be achieved. Over a period of 7 years, 84 angioplastic procedures (alone or associated with bronchoplasty) were performed at our institution. Partial PA resection was performed in 80 (95.2%) patients. Reconstruction was performed by running suture in 63 (75%) patients and using a pericardial patch in 17 (20.2%) cases (16 autologous and 1 heterologous). A complete PA resection and reconstruction was performed in four (4.8%) patients by a polytetrafluoroethylene (PTFE) prosthesis (n=2) and by a custom-made bovine pericardial conduit (n=2). The latter are the topic of this report.
