Is postoperative anticoagulation necessary after left innominate vein division in general thoracic surgery?

In this study, there was no case of mortality or severe morbidity among the patients with LIV resection. Moreover, there was no need to initiate routine anticoagulant therapy after the LIV division as the frequency of embolism in the LIV stump was low and was expected to disappear prior to starting anticoagulant therapy.
