biostudies-literatureUnknown3(4)Toyoda YChronic thromboembolic pulmonary hypertension is a rare but serious condition caused by pulmonary artery thrombi. Pulmonary thromboendarterectomy through median sternotomy is the "gold standard," but minimally invasive approaches are emerging. We describe a 22-year-old female athlete with May-Thurner syndrome and factor V Leiden and prothrombin mutations in whom pulmonary embolism developed. After failed thrombectomy, she underwent pulmonary thromboendarterectomy by J-shaped upper hemisternotomy. Circulatory arrest time was 24 minutes; cardiopulmonary bypass time, 131 minutes; and cross-clamp time, 51 minutes. This technique is feasible and safe, achieving comparable outcomes to full sternotomy while improving cosmesis, making it an appealing option for selected patients.Annals of thoracic surgery short reports893-896https://www.ebi.ac.uk/biostudies/studies/S-EPMC12712136biostudies-literatureMinimally Invasive Pulmonary Thromboendarterectomy by a J-Shaped Upper Hemisternotomy.PMC12712136Vijayapuri SMokashi SYanagida RSenzai MChauhan AKrishan KKehara HToyoda YfalseMinimally Invasive Pulmonary Thromboendarterectomy by a J-Shaped Upper Hemisternotomy.Chronic thromboembolic pulmonary hypertension is a rare but serious condition caused by pulmonary artery thrombi.
