Malignant neoplasms such as renal cell carcinoma may invade the inferior vena cava leading to a risk of pulmonary tumour embolization during surgical excision. Although massive pulmonary tumour embolism occurs relatively rarely, it can have catastrophic consequences. We report the case of an acute intraoperative pulmonary tumour embolism during resection ...

Pulmonary embolism (PE) is a common, treatable, highly lethal emergency, which despite advances in diagnostic testing, remains an under diagnosed killer. The mortality rate of diagnosed and treated pulmonary embolism ranges from 3-8%, but increases to about 30% in untreated pulmonary embolism. PE is a part of the spectrum of ...

Limb-salvage surgery for malignant tumors frequently involves reconstruction with an endoprosthesis anchored to bone by using third-generation cementing techniques. A 10-year-old boy with osteosarcoma had a pulmonary embolus caused by polymethylmethacrylate after having limb-salvage surgery that used high-pressure cementing techniques. He experienced transient postoperative chest pain, and a new wedge-shaped ...

Various congenital and acquired anomalies may affect the pulmonary arteries in adult patients. Congenital anomalies (proximal interruption, anomalous origin of the left pulmonary artery [pulmonary artery sling], and idiopathic dilatation of the pulmonary trunk) are usually found incidentally at chest radiography or computed tomography (CT). Acquired anomalies include diffuse or ...
