ABSTRACT
Pulmonary vein stump thrombosis (PVST) is uncommonly encountered postoperative in-situ thrombosis in the stump of pulmonary veins after lung resection. Data regarding the incidence and clinical behaviour of PVST are scarce. Thus, this study aims to investigate the incidence, clinical characteristics and outcome of PVST after lung resection in patients with lung cancer. Follow-up enhanced chest computed tomography (CT) scans acquired after the surgery were retrospectively reviewed to determine PVST presence for patients with lung cancer who underwent lung resection in two tertiary referral centres. Out of the 1885 patients with lung cancer who underwent lobectomy or more extensive lung resection, PVST was observed in 37 patients (2.0%) on their follow-up chest CT. Most stump thrombi were observed in the left superior pulmonary vein [35 (94.6%)] and in patients who underwent left upper lobectomy [34 (91.9%)]. At the last CT follow-up of each patient, 33 (89.2%) exhibited complete resolution, three partial resolution and one stabilization. Eleven (29.7%) patients received anticoagulant therapy after the diagnosis. The rate of complete PVST resolution did not differ significantly between the anticoagulation and nonanticoagulation groups. None of the PVST patients experienced systemic embolic events, regardless of anticoagulation. The PVST incidence diagnosed at routine chest CT follow-up following lung cancer surgery was 2%. PVST was characterized by a benign clinical course without progression and systemic embolization, regardless of anticoagulation. However, further studies are required to determine individualized therapeutic strategies, including anticoagulation.
