    Background:
    Arterial embolism including cerebral infarction is the major concern after surgery, because it can leave fatal or serious results. Recently, it is reported that pulmonary vein stump thrombosis is easy to occur after pulmonary resection, particular left upper lobectomy. However, it is unknown whether pulmonary vein thrombus is actually associated with cerebral infarction.
    
    Method:
    A totally 296 patients, underwent postoperative enhanced CT after left upper lobectomy in our hospital from September 2002 to December 2013, were retrospectively evaluated. We examined the association with pulmonary vein thrombus and cerebral infarction in both groups with thrombosis and without thrombosis formation. The relationship of patients’ background, clinical stage, pulmonary vein stump thrombus and postoperative cerebral infarction were analyzed.
    
    Result:
    Figure 121 patients (7.1 %) had a pulmonary vein thrombus, however all cases were asymptomatic and cerebral infarction was not developed. On the other hand, cerebral infarction developed in 15 patients of 275 patients without pulmonary vein thrombus formation. Only clinical stage was significantly relevant to cerebral infarction in univariate analysis. Table 1. Incidence of cerebral infarction according to a pulmonary vein stump thrombus
    
    
    
    Conclusion:
    Left upper lobectomy of the lung is well known to be a high risk of pulmonary vein stump thrombosis and cerebral infarction in all surgical procedures of the lung. However, pulmonary vein thrombus was not necessarily associated with the cerebral infarction after left upper lobectomy of the lung in this study.
