1/146. Aortic dissection in young patients with chronic hypertension.We describe four patients aged 14 to 21 years who developed acute aortic dissection. In three of the four patients, the course was fatal, despite aggressive medical and surgical intervention. All four patients had sustained systemic hypertension related to chronic renal insufficiency. The patients had no other identifiable risk factors for aortic dissection, including congenital cardiovascular disease, advanced atherosclerosis, vasculitis, trauma, pregnancy, or family history of aortic dissection. Although aortic dissection is rare in individuals younger than 40 years of age, young patients with sustained systemic hypertension are at increased risk for this serious and often fatal condition. physicians must be aware of this rare complication of hypertension and consider aortic dissection in the differential diagnosis of unusual chest, abdominal, and back pain in hypertensive children, adolescents, and young adults.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
2/146. Thoracic aortic aneurysm: a new etiology of pulmonary cavity.The most frequent chest X-ray finding of descending thoracic aortic aneurysm is an enlargement of medial mediastinum. Haemoptysis caused by thoracic aortic aneurysm is rare and, normally, when it occurs, it is due to an aorto-bronchopulmonary fistula. We report the case of an 88 year-old male, heavy smoker with arterial hypertension, who had been operated on for abdominal aneurysm five years before, whose unique symptom was scant haemoptysis and radiologically presented a cavity mass in the upper left lobe. autopsy revealed that the pulmonary cavity mass was due to a descending thoracic aortic aneurysm.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
3/146. Coronary artery aneurysms, aortic dissection, and hypertension secondary to primary aldosteronism: a rare triad. A case report.Primary aldosteronism is a relatively uncommon etiology of hypertension. plasma renin activity is suppressed in the majority of the cases but not always. plasma renin activity has been associated with increased vascular injury. The occurrence of vascular complications has rarely been reported with low plasma renin activity. The authors report a case of long-standing secondary hypertension due to primary aldosteronism with coronary artery aneurysms and aortic dissection. Diagnosing is important, for therapeutic intervention can be curative.- - - - - - - - - - ranking = 0.85714285714286keywords = hypertension (Clic here for more details about this article) |
4/146. Multivessel spontaneous coronary artery dissection in a patient with severe systolic hypertension: a possible association. A case report.Spontaneous coronary artery dissection (SCAD) is an uncommon cause of myocardial ischemia and infarction. hypertension has not been associated with SCAD. The authors report multivessel SCAD in an elderly woman with severe systolic hypertension. They postulate that hypertension of this degree may play a pathophysiologic role in the causation of SCAD.- - - - - - - - - - ranking = 0.85714285714286keywords = hypertension (Clic here for more details about this article) |
5/146. Aortic dissection: a rare complication of osteogenesis imperfecta.osteogenesis imperfecta (OI) is an inherited connective tissue disorder, a group that includes ehlers-danlos syndrome, Marfan's syndrome and pseudoxanthoma elasticum. OI is a heterogeneous disease of collagen I biosynthesis characterized by variable clinical phenotypes, including skeletal and cardiovascular manifestations. A 65-year-old man with OI who had extensive prior successful cardiac valve surgeries is described. He survived for 18 years after his initial valve surgery, but died of multiorgan failure and sepsis after repair of a spontaneous type A aortic dissection. This is the fourth reported case of aortic dissection secondary to OI and illustrates the extensive cardiovascular pathology associated with OI. Aggressive management of arterial dissection risk factors, such as systemic arterial hypertension, is advocated for patients with OI.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
6/146. Painless left hemorrhagic pleural effusion: An unusual presentation of dissecting ascending aortic aneurysm.Aortic dissection is a catastrophic event that is commonly associated with severe pain, massive hemorrhage, and high mortality. In this report, we present the case of a 31-year-old man who presented with painless, hemorrhagic left pleural effusion. Further investigation revealed a 9-cm dissecting ascending aortic aneurysm that was thought to be due to a congenitally bicuspid aortic valve. We suggest that ascending aortic aneurysm be included in the differential diagnosis of hemorrhagic pleural effusion, even in the absence of the classic features of aortic dissection, such as chest pain, advanced age, or history of hypertension.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
7/146. Emergency repair of incidentally diagnosed ascending aortic aneurysm immediately after caesarean section.A 36-yr-old pregnant woman with a history of hypertension presented at term for elective Caesarean section because of breech position. At preoperative examination, a diastolic murmur was found and transoesophageal echocardiography (TOE) revealed a large, 8.1-cm diameter ascending aortic aneurysm with severe aortic regurgitation and moderate pericardial effusion. Surgical repair was not considered to be urgently required. The patient was delivered electively by Caesarean section under epidural anaesthesia using invasive arterial pressure monitoring. TOE performed 6 h post-partum showed progressing pericardial effusion, for which emergency replacement of the aortic valve and ascending aorta were indicated. The epidural catheter was removed 4 h before starting the cardiopulmonary bypass procedure. arterial pressure was controlled by a titrated infusion of esmolol and clonidine. To improve uterine tone, the patient received an i.v. infusion of oxytocin throughout surgery. After implantation of an aortic composite graft and weaning from cardiopulmonary bypass, the patient was transferred to the intensive care unit. Awake and receptive to neurological evaluation, her trachea was extubated 4 h after surgery. Mother and baby made an uneventful recovery.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |

9/146. A case of aortic dissection with transient ST-segment elevation due to functional left main coronary artery obstruction.A 48-year-old man with a history of hypertension and diabetes mellitus was hospitalized with sudden onset of severe chest pain. He was in cardiogenic shock with a systolic pressure of 60 mm Hg. His electrocardiogram (ECG) showed ST-segment elevation in the precordial leads suggestive of acute anteroseptal myocardial infarction. The ST-segment returned to baseline after the systolic blood pressure rose to 100 mm Hg with the administration of sympathomimetic agents. aortography and transesophageal echocardiography demonstrated type A aortic dissection and aortic regurgitation. aortography and short-axis transesophageal echocardiography showed during diastole almost complete collapse of the true lumen of the ascending aorta caused by the intimal flap. The patient underwent surgical repair of the aortic dissection and implantation of Palmaz stents in the carotid arteries. Decreased blood pressure and the presence of aortic regurgitation accelerated the collapse of the true lumen during diastole in the ascending aorta, resulting in functional obstruction of the left main coronary artery, which may have been related to ST-segment changes in this case.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
10/146. Coronary artery erosion and dissection: an unusual complication of mitral annular calcification.This article describes a 42-year-old male patient with a longstanding history of insulin-dependent diabetes mellitus, systemic arterial hypertension, and chronic renal failure. The patient had severe mitral annular calcification (MAC) identified at autopsy. This MAC was of an amorphous, caseous-appearing type; it displaced the posterior mitral valve leaflet and extruded into the myocardium of the lateral and posterolateral left ventricle to involve the epicardial surface. The MAC produced extramural erosion of the wall, and dissection into the media, of the first left/obtuse marginal coronary artery. This coronary artery involvement by, and other complications of, MAC are discussed.- - - - - - - - - - ranking = 0.14285714285714keywords = hypertension (Clic here for more details about this article) |
