Summary:Abstract   OBJECTIVES Our goal was to evaluate the incidence and frequent sites of pulmonary vein stump thrombus (PVST) formation after pulmonary resection. METHODS This is a prospective multicentre observational study conducted by 14 institutions in Japan. Enrolled patients underwent anatomical pulmonary resection including lobectomy, bilobectomy, pneumonectomy, left upper trisegmentectomy or lingular segmentectomy. Postoperative contrast-enhanced computed tomography was performed in the early period after the pulmonary resection to evaluate the incidence of PVST. Furthermore, univariable and multivariable analyses were performed to assess the risk factors associated with PVST using a logistic regression model. RESULTS The status of PVST based on postoperative contrast-enhanced computed tomography scans was prospectively evaluated for 1040 patients. Postoperative computed tomography evaluation was performed for 3 (range: 1–84) days on average after the pulmonary resection. PVST was found in 127 (12.2%) patients with left-sided (23.3%) predominance compared to the right side (4.9%) (P
