1/9. Aorto caval fistula--the "bursting heart syndrome".Aorto caval fistula is one of the less well recognised complications of abdominal aortic aneurysm seen in accident and emergency departments. It presents in a number of different ways the commonest of which is high output congestive cardiac failure with warm peripheries. Initial diagnosis is based on the index of suspicion of the clinician. However, early diagnosis by the emergency physician and early surgery can markedly improve the patients prognosis.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/9. Aortobronchial fistula: a rare etiology for hemoptysis.Aortobronchial fistula is an extremely rare cause of hemoptysis. Aortobronchial fistula occurs in patients who have a history of thoracic vascular surgery. Because its symptoms are nonspecific, a high index of suspicion is critical if the physician is to detect it. The results of imaging studies (e.g., plain films, computed tomography, and angiography) and bronchoscopy are sometimes, but not always, diagnostic--another reason the diagnosis is difficult. Left untreated, mortality in patients with aortobronchial fistula is 100%. patients can be salvaged by a variety of techniques, including the placement of an endovascular stent. We describe the case of a 52-year-old man who came to us with hoarseness and hemoptysis, which proved to be underlying symptoms of aortobronchial fistula. He was treated successfully.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/9. Secondary aortoduodenal fistula.Secondary aortoenteric fistula (SAF) is now recognized as an uncommon but exceedingly important complication of abdominal aortic reconstruction. The complication often occurs months to years after the original surgery. The main clinical manifestation of the disease is always upper gastrointestinal bleeding. Treatment of the disease is early surgical intervention. The mortality is high if no prompt operation. We present a case of secondary aortoduodenal fistula (SADF) found 20 days after aortic reconstructive surgery, with the clinical presentation of upper gastrointestinal bleeding. Even immediate exploratory laparotomy was performed, the patient died 48 hrs after the surgical management. Because of the increasing number of elective aortic aneurysm repairs in the aging population, it is likely that more patients with SAF will present to the clinical physicians in the future. So, a high index of suspicion is necessary for prompt diagnosis and treatment of this actually life-threatening event.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
4/9. myocardial infarction resulting from nonatherosclerotic coronary artery diseases.myocardial infarction (MI) infrequently results from nonatherosclerotic coronary diseases such as coronary embolism, spasm, dissection, and arteritis. If these disorders are not considered in the differential diagnosis of MI, specific beneficial therapies would be overlooked. Because physicians see large number of patients with MI during their career, the likelihood that they will encounter patients with MI resulting from nonatherosclerotic diseases is high. Two cases are presented to highlight different etiologies and treatment approaches of nonatherosclerotic MI.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
5/9. Dysphagia aortica: a neglected symptom of aortoesophageal fistula.Aortoesophageal fistula, secondary to thoracic aortic aneurysm, is an uncommon cause of gastrointestinal bleeding that is uniformly fatal without surgical intervention. Typical symptoms are midthoracic pain and/or dysphagia followed by a usually short, albeit unpredictable, symptom-free interval and by a 'herald' haemorrhage, which is observed in 80% of patients before fatal exsanguinations. Dysphagia is present in 45% of patients, sometimes for several weeks, before the first bleeding occurs. However, dysphagia aortica is rarely considered in the differential diagnosis of dysphagia and lack of awareness, as well as symptom's underevaluation, both contribute to a significant diagnostic and therapeutic delay. We present a case of a 77-year-old woman who died for a bleeding AEF consequent to a thoracic aortic aneurysm and whose main symptom during the past 2 months was dysphagia, which was not taken seriously into consideration by her general practitioner. This case report emphasises that primary care physicians should be alerted to evaluate carefully the alarming symptoms like dysphagia -- especially in elderly patients -- before life threatening complications occur, as they are the ones who could suspect early the diagnosis and make a proper referral.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
6/9. Systemic embolization following thrombolytic therapy for acute myocardial infarction.We describe a patient with acute inferior myocardial infarction who developed a "saddle" aortic embolus during streptokinase infusion. Three months previously, this patient had sustained an anterior infarction, and an apical aneurysm was found. This patient's embolus had most probably originated from a left ventricular mural thrombus that had been dislodged by streptokinase. As fibrinolytic treatment is gaining wide acceptance, physicians should be aware of this rare, but possible, complication.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
7/9. Sudden death due to a paraganglioma of the organs of Zuckerkandl.A 20-year-old woman died suddenly in a hospital emergency room after presenting with nausea, vomiting, back pain, and hypertension. At autopsy, an extra-adrenal pheochromocytoma (paraganglioma) of the organs of Zuckerkandl was found, with microscopic focal myocardial necrosis similar to that described in death from adrenal pheochromocytomas. Tumors of the organs of Zuckerkandl are extremely rare; less than 100 such cases have been reported in the world's literature, and only six, including the present case, have presented as a sudden, unexpected death. The symptoms of catecholamine storm may mimic those of acute drug intoxications, leading to misdiagnosis by both clinical physicians and pathologists.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
8/9. Aortocaval fistulae: an occasional cause of congestive cardiac failure.Two atypical patients with spontaneous aortocaval fistulae with a successful outcome, are presented. Lack of physician awareness is considered an important contributor to diagnostic delay. A finding at cardiac catheterization is described. review of the English literature shows that satisfactory results in the management of this condition can now be expected.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
9/9. Diagnosis of esophageal varices by transesophageal echocardiography: a mimicker of aortic disease.The use of transesophageal echocardiography is well established in the emergency department diagnosis of traumatic aortic diseases. It has very high sensitivity and specificity compared with those of other tests. The physician performing transesophageal echocardiography should be aware of conditions that can mimic aortic pathologic conditions, thus leading to an incorrect diagnosis. We report a case in which the presence of previously undiagnosed esophageal varices mimicked traumatic aortic disease.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
