1/28. Paradoxical embolism. An old but, paradoxically, under-estimated problem.The theoretical model of paradoxical embolism requires the presence of four parameters, namely, arterial embolism, venous thrombus, abnormal intracardiac communication and right-to-left shunt. Many aspects, however, of this well known entity are under consideration; diagnosis is often difficult to be established and the long term efficacy of preventive measures is undefined. We comment on a case report of recurrent paradoxical embolism with popliteal vein thrombosis and patent foramen ovale, and we briefly review the literature.- - - - - - - - - - ranking = 1keywords = embolism (Clic here for more details about this article) |
2/28. Transitional cell carcinoma manifesting as acute cor pulmonale: cause of microscopic tumor embolism.Acute cor pulmonale is an uncommon manifestation of microscopic pulmonary tumor embolism. We describe the case of an 84-year-old man with a history of transitional cell carcinoma (TCC) of the urinary bladder who had acute cor pulmonale and died within a few hours after the onset of dyspnea. autopsy showed that the right ventricle was dilated without hypertrophy. Microscopic examination of the lung showed that the small arteries, arterioles, and capillaries were filled with micrometastases of TCC. Microscopic pulmonary tumor embolism has rarely been reported with TCC, and to the best of our knowledge, such a fulminant course has not been previously described in the English language.- - - - - - - - - - ranking = 0.85714285714286keywords = embolism (Clic here for more details about this article) |
3/28. Acute cor pulmonale due to microscopic tumour embolism as the first manifestation of hepatocellular carcinoma.Microscopic pulmonary tumour embolism is a rare cause of pulmonary hypertension. In most of the reported cases, symptoms develop over several days or weeks in patients previously diagnosed with malignant diseases. In our case, a 41-year-old man with an unremarkable medical history presented with respiratory failure that led to death less than 48 h from the onset of symptoms. autopsy revealed massive microscopic pulmonary tumour embolism and a multifocal hepatocellular carcinoma. This case report is exceptional because it describes a very rapid clinical progression, and because acute cor pulmonale was the first manifestation of a previously undiagnosed neoplastic disease.- - - - - - - - - - ranking = 0.85714285714286keywords = embolism (Clic here for more details about this article) |
4/28. Microscopic pulmonary tumour embolism: an unusual presentation of thymic carcinoma.The present report describes the first reported case of microscopic pulmonary tumour embolism (MPTE) from thymic carcinoma. The carcinoma was discovered during an autopsy in a 55-year-old man who had undergone surgery for a pilonidal sinus two weeks before presentation. Pulmonary thromboembolism was suspected. This case was unusual because MPTE has never before been associated with thymic carcinoma, MPTE was the first clinical indication of an occult malignancy, and the clinical presentation was that of sudden onset of dyspnea associated with acute cor pulmonale. The cause of death was determined to be hypoxia secondary to extrinsic compression of the right pulmonary artery and extensive tumour emboli in the small arteries, arterioles and venules of the pulmonary parenchyma. A review of the clinical presentation and diagnosis of MPTE is included.- - - - - - - - - - ranking = 1.4690392594631keywords = thromboembolism, embolism (Clic here for more details about this article) |
5/28. Pulmonary tumor embolism: a review of the literature.dyspnea in a patient with cancer may have several causes, including infection, thromboembolism, metastases, and therapeutically induced cardiopulmonary disease. Pulmonary tumor embolism is an uncommon cause. Occlusion of the pulmonary microvasculature by tumor cells and associated thrombi can produce a subacute and progressive clinical picture that resembles thromboembolic disease. Unfortunately, microscopic tumor embolism is recognized rarely before death because of difficulty in establishing the diagnosis. We provide a review of the literature about the evaluation and diagnosis of this rare clinical entity.- - - - - - - - - - ranking = 1.6118964023203keywords = thromboembolism, embolism (Clic here for more details about this article) |
6/28. Successful pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension associated with anticardiolipin antibodies: report of a case.Chronic pulmonary thromboembolism with pulmonary hypertension is a rare but most unique syndrome in the broad spectrum of pulmonary embolism. This report describes a successful pulmonary thromboendarterectomy performed for a totally occluded right pulmonary artery on a 43 year old man who presented with positive cardiolipin antibodies. The surgery was performed through a median sternotomy with cardiopulmonary bypass and intermittent periods of deep hypothermic circulatory arrest. We are convinced that this method allows for complete removal of the thrombotic obstruction and should be the procedure of choice for patients with very proximal obstruction of a pulmonary artery.- - - - - - - - - - ranking = 1.4398035155361keywords = thromboembolism, pulmonary embolism, embolism (Clic here for more details about this article) |
7/28. Chronic cor pulmonale: a rare complication of undiagnosed pacemaker lead endocarditis.Pacemaker lead infection is a rare life-threatening complication of permanent transvenous pacing. We describe the case of a young man who suffered recurrent undiagnosed septic pulmonary embolisms from pacemaker lead vegetations inducing chronic cor pulmonale with major pulmonary arterial hypertension. The potential complications of transvenous pacing and the systematic use of transesophageal echocardiography are emphasized.- - - - - - - - - - ranking = 0.68504997035874keywords = pulmonary embolism, embolism (Clic here for more details about this article) |
8/28. Subacute cor pulmonale due to tumor embolism.We describe a patient wih subacute cor pulmonale caused by tumor emboli in the lungs. A 64-year-old female suffering from a subacute progressive cough and shortness of breathing died of severe pulmonary hypertension seven days after admission. Neither chest CT scans nor lung perfusion scintigraphy showed any abnormal findings. Microscopic examination after an autopsy revealed diffuse intravascular tumor emboli occluding not only the small pulmonary arteries and arterioles, but also the lymphatic vessels, which were suggested to be metastases of a breast carcinoma resected five years previously. Thus, pulmonary tumor embolism should be considered in the differential diagnosis of primary pulmonary hypertension, particularly in patients with a past history of cancers.- - - - - - - - - - ranking = 0.71428571428571keywords = embolism (Clic here for more details about this article) |
9/28. Fatal cor pulmonale caused by pulmonary tumor microembolism in a patient with occult gastric cancer.BACKGROUND: A fatal pulmonary tumor microembolism is rarely caused by an occult gastric cancer. methods AND RESULTS: We report the case of a 40-year-old woman who died after 3 days of progressive dyspnea, cough, and pulmonary hypertension. Postmortem examination demonstrated the presence of an occult diffuse-type gastric carcinoma, which had caused emboli in about 80% of small pulmonary arteries and arterioles. Despite an interatrial defect in the fossa ovalis, no parenchymal metastases were documented. CONCLUSION: Pulmonary tumor microembolism may be suspected in patients complaining of unexplained progressive dyspnea and who develop acute or subacute cor pulmonale.- - - - - - - - - - ranking = 0.85714285714286keywords = embolism (Clic here for more details about this article) |
10/28. Subacute cor pulmonale due to tumor embolization.Pulmonary tumor embolism is a rare but well-documented cause of respiratory failure in patients with cancer. This entity is probably clinically underrecognized and may represent an important cause of mortality and morbidity in patients with cancer. Pulmonary tumor embolization may present at any stage of the patient's illness and indeed may be the first presentation of an occult carcinoma. In a review of 1069 nonmedicolegal autopsy protocols, we recently encountered three cases in which death had occurred from subacute cor pulmonale due to tumor embolization from breast, lung, and ovarian carcinoma. Recent advances in cytologic examination of blood samples obtained from Swan-Ganz catheters may prove useful in the diagnosis of this entity.- - - - - - - - - - ranking = 0.14285714285714keywords = embolism (Clic here for more details about this article) |
