1/27. Successful non-operative management of right coronary artery perforation during percutaneous coronary intervention in a patient receiving abciximab and aspirin.We report a case of successful non-operative treatment of coronary artery perforation that occurred during percutaneous transluminal coronary angioplasty. The patient was receiving abciximab, aspirin and heparin. The perforation was recognized immediately and managed by partial reversal of heparin and inflation of a non-compliant balloon at the perforation site. The perforation sealed completely. The patient was discharged asymptomatic the following day.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/27. Left internal mammary artery graft perforation repair using polytetrafluoroethylene-covered stents.The increase in the use of the left internal mammary artery (LIMA) as graft of choice to the left anterior descending coronary artery for conventional and minimally invasive coronary artery bypass surgery has led to an increased incidence of LIMA pathologic lesions early after surgery. The lesion, commonly located in the body of the LIMA graft, is usually caused by mechanical injury during harvesting of the vessel. In this context, percutaneous intervention with stent implantation can be complicated by vessel rupture, which usually requires emergency surgical repair. We describe two cases of stent implantation in newly placed LIMA grafts complicated by vessel rupture, which were successfully repaired using polytetrafluoroethylene-covered stents.- - - - - - - - - - ranking = 0.2keywords = coronary (Clic here for more details about this article) |
3/27. Missiles in the heart causing coronary artery disease 44 years after injury.We present a case of two missiles in the heart causing coronary artery disease with first onset 44 years after the injury. The missiles were close to the right coronary artery and the left anterior descending coronary artery. The missiles initiated local arteriosclerosis in these vessels, with an extremely stretched time frame from injury to the onset of symptoms for coronary artery disease.- - - - - - - - - - ranking = 0.8keywords = coronary (Clic here for more details about this article) |
4/27. The use of off pump surgery for management of penetrating coronary artery injury.Penetrating trauma to the chest leading to coronary artery injury is associated with a high mortality rate, especially in the case of injury to the left anterior descending (LAD) coronary artery. The mortality rate remains high whether they are managed with primary ligation or with coronary artery bypass grafting using conventional cardiopulmonary bypass techniques. We report a case of proximal LAD coronary artery injury successfully treated with off pump coronary revascularisation.- - - - - - - - - - ranking = 0.9keywords = coronary (Clic here for more details about this article) |
5/27. Different types of coronary artery wall injury following cutting balloon angioplasty.The cutting balloon is a device that enlarges atherosclerotic coronary arteries by a combination of plaque incision and dilation. This peculiar mechanism would account for a better immediate result achieved at the cost of minimal vessel wall trauma. Coronary perforation is however a potential complication. No systematic data have been reported as to which angiographic lesion characteristic may predict the occurrence of complications after cutting balloon angioplasty. This case report study deals with different types of coronary artery wall injury complicating cutting balloon angioplasty and detected by intravascular ultrasound.- - - - - - - - - - ranking = 0.6keywords = coronary (Clic here for more details about this article) |
6/27. Penetrating injury of the chest and coronary arteriovenous fistula.An unusual case of coronary artery fistula, due to a stab wound in the chest in a 17-year-old male patient, with a resultant acute inferior myocardial infarction is presented. At surgery, complete transection of the right coronary artery was found, which formed a fistulous communication with both the right atrium and the right ventricle. The development of a continuous murmur in the period immediately after the injury, the absence of hemopericardium, and multiple cardiac-chamber involvements were unique features of the case. The inferior myocardial wall was akinetic due to infarction and did not improve following revascularization surgery. A brief review of the literature is also presented.- - - - - - - - - - ranking = 0.6keywords = coronary (Clic here for more details about this article) |
7/27. Delayed presentation of injury to the sinus of valsalva with aortic regurgitation resulting from penetrating cardiac wounds.A 39-year-old man had attempted to commit suicide using a small knife to penetrate the anterior chest wall. An emergency operation was performed successfully to repair the penetrating cardiac injury of the right ventricular outflow tract without using cardiopulmonary bypass. Two years after the operation, he was complained of dyspnea and a continuous murmur was detected. echocardiography and cardiac catheterization revealed aorto-right ventricular fistula in the sinus of valsalva with aortic regurgitation. In operation, the healed laceration of the right coronary cusp and the fistula between aorta and right ventricle were identified. The fistula was closed using a Dacron patch and the aortic valve was replaced with a mechanical valve. Long-term follow-up of penetrating thoracic injuries is important for detecting underlying intracardiac lesions.- - - - - - - - - - ranking = 0.1keywords = coronary (Clic here for more details about this article) |
8/27. death by chainsaw: fatal kickback injuries to the neck.Each year over 3 million new chainsaws are sold in the united states. The operation of these newer saws combined with the millions of older chainsaws in circulation results in over 28,000 chainsaw-related injures annually. The majority of the injuries involve the hands and lower extremities with less than 10% involving injuries to the head and neck regions. Deaths while operating a chainsaw are extremely rare. The most common hazards associated with chainsaws are injuries caused by kickback, pushback, and pull-in. Kickback is the most common and poses the greatest hazard. Kickback occurs when the rotating chain is stopped suddenly by contact with a more solid area throwing the saw rapidly backward toward the operator. The cause of most injuries can be traced to improper use of the saw or poor judgment on part of the operator. We present two fatal chainsaw deaths; one with an older style saw, and the other with a modern type. In both cases the victims died from fatal injuries received to the neck region from a chainsaw kickback. The first case involved a 49-year-old white male operating an older style chainsaw with limited safety features. The second case involved a 38-year old white male who was operating a newer model chainsaw equipped with a low kickback chain in an unsafe manner.- - - - - - - - - - ranking = 0.0054445510117643keywords = circulation (Clic here for more details about this article) |
9/27. Metallic fragment embolization to the middle cerebral artery.A 25-year-old male was wounded accidentally in the neck by a metallic fragment, which penetrated his right carotid artery and migrated within the ipsilateral middle cerebral artery. Clinical and laboratory findings over a 16-month-period are reported. Problems arising from the presence of metallic emboli to the cerebral circulation are discussed on the basis of the pertinent literature.- - - - - - - - - - ranking = 0.0054445510117643keywords = circulation (Clic here for more details about this article) |
10/27. Penetrating cardiac injury--to close the pericardium or not? A case report.Many trauma surgeons who treat penetrating cardiac injuries do not routinely suture the pericardium closed after repairing the heart. The patient reported here died from exsanguination during attempts to mobilise the heart which had adhered to the sternum. With the increasing demand for coronary artery surgery and the high incidence of carcinoma of the oesophagus in south africa, both of which require access to the mediastinum, we recommend that in the trauma setting, the pericardium be closed to facilitate future surgery if required.- - - - - - - - - - ranking = 0.1keywords = coronary (Clic here for more details about this article) |
