1/81. An unusual iatrogenic cause of right coronary air embolism.A 62-year-old woman undergoing redo mitral valve replacement was noted to have persistent intracardiac air following standard deairing procedures. Transesophageal echocardiography (TEE) identified air bubbles entering the left atrium from the right superior pulmonary vein. Exploration of the pleural cavity revealed a fistula between the pulmonary parenchyma and the right superior pulmonary vein caused by the atriotomy closure suture transfixing the edge of the lung, which was repaired with immediate disappearance of the air emboli. This demonstrates that transesophageal echocardiography is an invaluable aid to ensuring complete deairing after open heart procedures.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/81. air embolism in the right coronary artery occurring during the left coronary angioplasty using the guiding catheter with a side hole.Coronary air embolism is one of the inadvertent complications of coronary angioplasty. We report two rare cases of complicating air embolism in the right coronary artery occurring during control left coronary angiography using a guiding catheter with a side hole, just prior to a coronary intervention procedure for a left coronary artery lesion. The air seemed to be injected into the right coronary artery through the side hole. When we use an angiographic or guiding catheter with a side hole, we should be aware that an air embolism can occur in the contralateral coronary artery and should carefully and repeatedly perform aspiration of the catheter.- - - - - - - - - - ranking = 3.75keywords = coronary (Clic here for more details about this article) |

4/81. Coronary air embolism treated by bubble aspiration.We describe a case of coronary air embolism following cardiac catheterization, with all the signs and symptoms of an acute coronary event. Thanks to the rapid and effective aspiration of the air bubble from the distal artery, blood flow was restored and the clinical picture was resolved.- - - - - - - - - - ranking = 0.5keywords = coronary (Clic here for more details about this article) |
5/81. Normal diffusion-weighted imaging in cerebral air embolism complicating angiography.We report a case of cerebral air embolism resulting from accidental air infection during cerebral angiography. A 60-year-old man was accidentally injected with air via the left subclavian artery. Angiography demonstrated air within the basilar artery. The patient showed signs of posterior circulation ischaemia (confusion, blindness, gaze palsy and hemiparesis). However, MRI, including diffusion-weighted imaging, showed no abnormality 4 h later. The patient was treated with hyperbaric oxygen within 5 h of the embolism. All symptoms and signs resolved completely within a week.- - - - - - - - - - ranking = 0.31607443076846keywords = circulation (Clic here for more details about this article) |
6/81. Fatal air embolism during thoracotomy for gunshot injury to the lung. Report of a case.Fatal coronary air embolism occurred during thoracotomy in a patient with a gunshot wound involving the hilum of the right lung. embolism was observed during a second period of failure of heart action. Evidently, air entered the pulmonary veins from the bronchus, which was receiving positive-pressure ventilation. The literature contains reports of only 3 similar cases, but we suspect that air embolism may be responsible for death and morbidity in additional cases in which accidental or iatrogenic lung trauma has produced a pathway between the bronchial tree and the pulmonary veins.- - - - - - - - - - ranking = 0.25keywords = coronary (Clic here for more details about this article) |
7/81. Chronological changes in cerebral air embolism that occurred during continuous drainage of infected lung bullae.We present a 43-year-old man with cerebral air embolism that occurred during continuous drainage of infected lung bullae. This complication is extremely rare, and may have been caused by the passage of air into the pulmonary venous circulation through a bronchovenous fistula and/or damaged pulmonary vessels. air densities were demonstrated along the right frontal gyri on a CT performed 1 h after the onset of embolism, then moved to the deep cortex after 2.5 h. Three days later, a cortical infarct accompanied with extensive white matter edema in the right frontal lobe was confirmed by MRI. These CT and MRI findings may indicate the passage of intravascular air from the superficial to the deep cortex and subsequent cerebral infarction.- - - - - - - - - - ranking = 0.31607443076846keywords = circulation (Clic here for more details about this article) |
8/81. A dynamic bubble trap reduces microbubbles during cardiopulmonary bypass: a case study.Microemboli passing to the cerebral circulation during cardiopulmonary bypass can contribute to postoperative neurologic dysfunction. Many studies conclude that air microbubbles predominantly are responsible for this problem. A dynamic bubble trap (DBT) was developed to diminish the number of microbubbles in the arterial line of extracorporeal circulation. The DBT is able to substantially reduce the number of air microbubbles, as shown in two patients undergoing coronary artery bypass grafting, where a high number of microbubbles was assessed. Although a 40-micron arterial filter was used, many bubbles larger than 40 microns occurred in the arterial line. The DBT reduced the number of large microbubbles from 2,267 to 67 in patient 1 and from 897 to 61 in patient 2.- - - - - - - - - - ranking = 0.88214886153691keywords = circulation, coronary (Clic here for more details about this article) |
9/81. Successful resuscitation of patient with massive coronary air embolism occluding two vessels during coronary angiography--a case report.Massive coronary air embolism is usually disastrous although successful resuscitation has been reported previously. To what extent a patient with coronary air embolism can be resuscitated is not known. The authors report a rare case of massive air embolism to the left coronary arteries and successful resuscitation by vigilantly maintaining an effective driving force to dissipate the air lock.- - - - - - - - - - ranking = 2.75keywords = coronary (Clic here for more details about this article) |
10/81. Fatal air embolism during female autoerotic practice.air embolism has been described in pregnant women and is a classic cause of death during attempted abortion by syringing. Death was caused by the introduction of an amount of air sufficient to cause a substantial air lock in the heart, pulmonary trunk or arteries. If the surface of the placenta has been stripped by the syringe, venous spaces are opened and air can pass into the circulation. Orogenital sex with vaginal insufflation can also cause air embolism during pregnancy. We report a case of air embolism in a 40-year-old non-pregnant woman subsequent to vaginal insertion of a foreign body (carrot) for an autoerotic purpose. The mechanism is roughly similar to syringing, the foreign body acting like a piston to displace a sufficient amount of air. In the present case, the endometrium stripping was probably due to the presence of an intrauterine device. As such risks may often be encountered and as, to our knowledge, no similar case has previously been reported, we may speculate if such air embolisms are underdiagnosed or dissimulated by the partners when questioned by the medical rescue teams.- - - - - - - - - - ranking = 0.31607443076846keywords = circulation (Clic here for more details about this article) |
