Incidence and clinical features of the incidentally found vascular stump thrombus during routine follow up after oncologic lung surgery

We aimed to evaluate the incidence and clinical features of vascular stump thrombus after oncologic lung surgery. A retrospective analysis of records from our institutional database dated between 2009 and 2016 was performed. Data regarding demographics, clinical presentation, medication use, operative findings, pathology, and radiologic findings were retrieved. The study cohort consisted of 648 oncologic surgeries for primary lung cancer. The incidence of thrombus in the entire population was 5.7% (37/648). Most thrombi were incidentally found on follow-up chest computed tomography scans. Univariate Cox proportional hazard analysis showed that age (p = 0.02), adjuvant therapy (p
