1/27. Inverse paradoxical embolism in a patient on chronic hemodialysis with aortic bacterial endocarditis.We present a 45-year-old patient on chronic hemodialysis who suffered aortic endocarditis by staphylococcus haemolyticus after bacteremia associated with a venous catheter, which was used temporarily during the maturing phase of a Cimino-Brescia arteriovenous fistula in the left forearm. Three weeks after starting antibiotic therapy, the patient suffered a septic pulmonary embolism. The catheter had been removed 4 weeks before the embolism. thrombophlebitis of lower limbs, infection or thrombosis of the vascular access, and the involvement of right-sided cardiac structures were all discarded. We assumed that the pulmonary episode was probably a consequence of the paradoxical passage of embolic material, detached from the aortic valve, from arterial to venous circulation through the arteriovenous fistula.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
2/27. A case of acute pulmonary embolism and acute myocardial infarction with suspected paradoxical embolism after laparoscopic surgery.We describe the case of a 59-year-old Japanese man who had an acute pulmonary embolism in addition to acute myocardial infarction after a laparoscopic cholecystectomy. The posterior descending coronary artery was totally occluded. and direct percutaneous transluminal balloon angioplasty was performed. The pulmonary embolism was diagnosed by lung perfusion scanning and was treated with anticoagulant therapy. A patent foramen ovale and right-to-left atrial shunting of blood were detected by contrast transesophageal echocardiography. Paradoxical embolism is a rare complication of pulmonary embolism and may have been responsible for the acute myocardial infarction in our patient.- - - - - - - - - - ranking = 0.7940150000321keywords = coronary (Clic here for more details about this article) |
3/27. Paradoxical embolism-report of a case involving four organ systems.Paradoxical embolism through a patent foramen ovale (PFO) can involve multiple organs simultaneously. The most commonly involved sites are the cerebrum and the extremities. Paradoxical embolism to coronary arteries or upper extremities is relatively uncommon. We report a case of acute pulmonary embolism and paradoxical embolism through a patent foramen ovale involving the left upper extremity, brain, and coronary artery. early diagnosis in the emergency department was made by a trans-esophageal echocardiogram, and the patient was successfully treated with intravenous t-PA and heparin. patients with acute pulmonary embolism or deep venous thrombosis who also develop signs of systemic embolism should be evaluated for a patent foramen ovale.- - - - - - - - - - ranking = 1.5880300000642keywords = coronary (Clic here for more details about this article) |
4/27. Paradoxical embolism causing fatal myocardial infarction in a newborn infant.A neonate who presented with circulatory collapse was found to have myocardial infarction caused by thrombotic occlusion of the left main coronary artery. At autopsy, a thrombus was found in the ductus venosus making paradoxical embolism through the foramen ovale the most likely mechanism of coronary occlusion.- - - - - - - - - - ranking = 1.5880300000642keywords = coronary (Clic here for more details about this article) |
5/27. Acute myocardial infarction caused by paradoxical coronary embolization in a patient with a patent foramen ovale.We describe the case of a young woman without cardiac risk factors who had an acute inferoapical myocardial infarction. Coronary angiographic appearance was consistent with thrombus in the distal left anterior descending coronary artery. A patent foramen ovale with moderate right-to-left shunting after the valsalva maneuver was detected by contrast transesophageal echocardiography. No other cardioembolic source was identified. Paradoxical embolization through a patent foramen ovale is a rare phenomenon, which appeared to have resulted in myocardial infarction in this patient.- - - - - - - - - - ranking = 3.9700750001605keywords = coronary (Clic here for more details about this article) |
6/27. Paradoxical embolus: an unusual indication for upper limb amputation.Paradoxical emboli occur when venous embolic material passes into the arterial circulation (via a right-to-left cardiac shunt). The association of paradoxical emboli and arterial ischaemia has been described previously, especially with respect to cerebral infarcts. We describe a case in which double paradoxical emboli following a long haul flight, resulted in emergency amputation of an upper limb. amputation resulting from a paradoxical embolus has not previously been described.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
7/27. Paradoxical air embolism during hepatic resection.Systemic venous air embolism is a serious complication in patients with chronic liver disease having liver surgery. Intrapulmonary arteriovenous shunting can permit air emboli to pass into the systemic circulation. We describe a case of paradoxical air embolism detected by transoesophageal echocardiography in a patient with cirrhosis who was having a hepatic resection.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |

Paradoxical embolism to the left main coronary artery: visualization by transesophageal echocardiography.A case of myocardial infarction is described with transesophageal echocardiography visualization of left main coronary artery thrombus arising from paradoxical embolism of mobile venous thrombus by patent foramen ovale.- - - - - - - - - - ranking = 3.9700750001605keywords = coronary (Clic here for more details about this article) |
9/27. Paradoxical embolism in the left main coronary artery: diagnosis by transesophageal echocardiography.We describe a patient with a paradoxical coronary embolism diagnosed by transesophageal echocardiography. The patient developed a stroke followed by a myocardial infarction. coronary angiography showed an obstruction of the left main coronary artery. Transesophageal echocardiography showed the mechanism of the neurologic and cardiac events to be a paradoxical embolism. Emergency surgical retrieval of the thrombus lodged in the left main coronary ostium and of a separate thrombus traversing a patent foramen ovale was performed. To our knowledge, direct visualization of the paradoxical coronary embolism by echocardiography has not been reported previously. We discuss mechanisms responsible for paradoxical coronary embolism and review the literature pertaining to this condition.- - - - - - - - - - ranking = 7.1461350002889keywords = coronary (Clic here for more details about this article) |
10/27. A case of pregnancy with a history of paradoxical brain embolism.brain embolisms in younger persons are rare but are often caused by a paradoxical embolism, the embolic entry of a venous thrombus into the systemic circulation through a right-to-left shunt. A 27-year-old pregnant woman presented with hemiplegia that had been treated with an antiplatelet agent since the occurrence of a paradoxical brain embolism via the pulmonary arteriovenous fistula. A tendency of hypercoagulation is generally observed during pregnancy, so a patient with this condition has a strong risk factor for venous thromboembolism during pregnancy and even more so for arterial thromboembolism under the intense strain of labor, which is much stronger than that of the valsalva maneuver. This case had been controlled well with an antiplatelet agent and an anticoagulant while the levels of coagulation and fibrinolytic factors were monitored and was followed by a successful pregnancy outcome.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
