    Abstract:
    OBJECTIVE: We report our experience with 93 consecutive pulmonary artery reconstructions during pulmonary lobectomy with regard to morbidity, mortality, and long-term survival. METHODS: Clinical records of all patients who underwent lobectomy with partial or circumferential pulmonary artery resection in a single institution during an 8-year period were reviewed retrospectively. RESULTS: Lobectomy with partial (n = 90) or circumferential (n = 3) pulmonary artery resection was carried out in 93 patients. Indications for surgical intervention were non-small cell lung cancer in 87 patients and other malignancy in the remaining 6 patients. Bronchial sleeve resection was associated in 23 patients. Neoadjuvant chemotherapy had been administered in 34 cases because of cN2 disease. Operative mortality was 5.4%. Postoperative complications occurred in 27 (29.0%) patients. All the patients underwent contrast-enhanced computed tomographic scanning 6 to 8 weeks postoperatively, which always showed patency of the pulmonary arteries. In the whole population median and 5-year survivals were 40 months and 39.4%, respectively. Disease-free survival was 41.4% at 5 years. Among patients with non-small cell lung cancer, at univariate analysis, tumor size of less than 3 cm; presence of vascular peritumoral emboli, intratumoral emboli, or both; and dyspnea influenced 5-year survival. Multivariate analysis showed that the size of the primary tumor and the presence of vascular emboli were independent factors of worse outcome. CONCLUSIONS: Lobectomy with arterial sleeve resection has acceptable mortality and no specific complications. Late results in terms of survival are satisfactory.
