Key result
A 64-MDCT scan in a 76-year-old male revealed a network of pulmonary vein thrombi connecting the pulmonary veins and left atrium, highlighting PVT as a potential risk factor for ischemic stroke.
Case Report (n=1)
Pulmonary vein thrombi can form an extensive network extending into the left atrium, potentially representing an under-recognized risk factor for ischemic stroke following cardiac surgery.
Alerts clinicians to possible PVT in unexplained stroke; single case leaves causal role and screening open.
Stroke remains a devastating complication following cardiac surgery. Pulmonary vein thrombi (PVT) are believed to be rare, but I have reported 37 cases of PVT in elderly patients with chest pain since 2012, indicating that PVT are not unusual. The present case showed that PVT can make a network among four pulmonary veins and left atrium. Currently, PVT are not recognized as a risk factor for ischemic stroke, especially following cardiac surgery. A 76-year-old male was examined by 64-slice multidetector CT (64-MDCT) to assess chest pain. The 64-MDCT scan revealed thrombi in the left upper and lower pulmonary veins, the right upper and lower pulmonary veins and the left atrium (LA) as the defects of contrast enhancements. The LA thrombi seemed to be connected to PVT forming a network of thrombi. To avoid stroke following cardiac surgery, it is important to cope with PVT. How to treat PVT during cardiac surgery should be developed.

Hidekazu Takeuchi (2014) conducted a case report in Pulmonary vein thrombi (n=1). Pulmonary vein thrombi was evaluated. A 64-MDCT scan in a 76-year-old male revealed a network of pulmonary vein thrombi connecting the pulmonary veins and left atrium, highlighting PVT as a potential risk factor for ischemic stroke.
