Frequency and Predictors of Pulmonary Arterial Stump Thrombosis following Pneumonectomy or Lobectomy

The objectives of this study were to analyse the prevalence and risk factors of PAST and the clinical significance (follow-up, treatment, resolution, etc.) in patients with pneumonectomy/lobectomy. Methods: All adult cases who underwent pneumonectomy/lobectomy in our hospital for any reason, and who underwent control contrast-enhanced thoracic CT during the follow-up period were included in the study. Demographic and clinical features of the patients, data about surgery and the features of thrombi were recorded. Results: During the 4-years study period, a total of 454 patients underwent pneumonectomy/lobectomy (93 pneumonectomy, 361 lobectomy). Among the patients, 202 patients (50 pneumonectomy, 152 lobectomy) with at least one follow-up thorax CT were included into the analyses. PAST was detected in 9 (4.5%) of 202 patients and mostly seen in patients with pneumonectomy (lobectomy: 2.6% vs. pneumonectomy: 10%, p=0.043) and in patients whose pulmonary artery were ligated by stapler (suture ligation 1% vs. stapler: 7.4%, p=0.034). Pulmonary artery stump was also longer in patients with PAST (8.48 ±11.22 mm vs. 23.55±11.22 mm, p
