Key result
Systemic anticoagulation resolves chest pain in delayed pulmonary artery stump thrombosis.
Why the study?
Pulmonary artery stump thrombosis is a recognized complication after pneumonectomy, but delayed development and the role of anticoagulation remain unclear.
Case Report (n=1)
This case highlights the rare delayed presentation of a pulmonary artery stump thrombus and suggests systemic anticoagulation may be beneficial for specific subsets of symptomatic patients with convex thrombi.
Pulmonary artery stump thrombosis is a recognized complication after pneumonectomy. However, to our knowledge, there is only one case report of delayed development of this complication. We report the case of a 68 year-old man who presented with chest pain nearly ten years after undergoing a right pneumonectomy for lung cancer. Workup identified a pulmonary artery stump thrombosis. Due to the acute onset of his symptoms, the patient was anticoagulated, and his chest pain resolved. While the literature suggests that anticoagulation is not generally required for stump thromboses, we highlight features of this case that may indicate an increased risk of clinically important sequelae. Taking previous reports into account, we argue that a specific subset of patients with stump thrombosis may benefit from systemic anticoagulation.
