1/13. Ischemic papilledema in giant-cell arteritis. Mucopolysaccharide deposition with normal intraocular pressure.A 68-year-old man died 18 days after the onset of ischemic optic neuropathy caused by histologically proven giant-cell arteritis. On histopathologic study of the eye, ischemic necrosis of the prelaminar and retrolaminar optic nerve was seen, along with the massive presence of acid mucopolysaccharides sensitive to testicular hyaluronidase. This finding was interpreted as an intrusion of vitreal material resulting from breaks in the internal limiting membrane and the pressure gradient from intraocular to extraocular tissues, an analogy to Schnabel degeneration in acute glaucoma.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/13. Progressive diffuse aortic stenosis after localized supravalvular aortic stenosis repair.A 6-year-old boy presented with diffuse stenosis of the aortic arch. He had undergone patch augmentation for localized supravalvular aortic stenosis at 2 years of age. Before the initial operation, the aortic arch and descending aorta were noticed to be hypoplastic with a diameter of 60 to 73% of that of the aortic annulus, without a pressure gradient. 4 years later, progressive diffuse stenosis of the aortic arch with a diameter of 42% of that of the aortic annulus was found. reoperation, consisting of patch augmentation of the aortic arch, was carried out. A pressure gradient of 40 mmHg distal to the repair was newly recognized, again. This is a rare case of supravalvular aortic stenosis, which required reoperation because of the progression of diffuse stenosis of the distal aorta.- - - - - - - - - - ranking = 0.4keywords = pressure (Clic here for more details about this article) |
3/13. Surgical management of tunnel-like subaortic stenosis via ventricular septal defect in a patient with the interrupted aortic arch.A 24-day-old male with interrupted aortic arch (type B), ventricular septal defect, and tunnel-like subaortic stenosis underwent a one-stage surgical treatment. The operative procedure comprised reconstruction of the aortic arch, transatrial excision of the subaortic fibromuscular tissue via the ventricular sepatal defect, and patch closure of the defect. The patient tolerated the procedure well and the postoperative echocardiography demonstrated a residual pressure gradient across the left ventricular outflow tract of 20 mmHg. Our result suggests that the transatrial surgical management of subaortic stenosis via the ventricular sepatal defect produces a safe and promising surgical option.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
4/13. Paroxysmal hypertension in aortitis syndrome.Three patients with aortitis syndrome ehibited paroxysmal hypertension which seemed to result from baroreceptor dysfunction. All of the patients had signs of active inflammation of aortitis syndrome and stenotic carotid and subclavian arteries. During the attacks, the blood pressure rose to at least 230 mm. Hg systolic and the heart rate exceeded 100. However, with prolonged administration of steroid hormones, the attacks ceased. In two patients with dilated thoracic aortas and aortic regurgitation, the attacks of paroxysmal hypertension occurred without apparent precipitating factors and were followed by anginal pain with marked ST depression. The sympathicotonic state resulting from the disturbance of the baroreceptors was considered to be responsible for the attacks. In another patient, the attacks occurred in the course of treatment with a steroid hormone and were provoked only by voluntary micturition. This post-micturition hypertension was presumed to be an expression of abnormal overshooting following a fall in blood pressure after voiding.- - - - - - - - - - ranking = 0.4keywords = pressure (Clic here for more details about this article) |
5/13. takayasu arteritis in a middle-aged Caucasian woman: clinical course correlated with duplex ultrasound and angiography.takayasu arteritis, an occlusive arteritis usually involving the aorta and its major branches, occurs most commonly in young oriental women. The authors report the case of a 54-year-old caucasian woman with takayasu arteritis who initially presented with the inflammatory manifestations of fever and markedly accelerated erythrocyte sedimentation rate. Over 2 months she developed evidence of vascular insufficiency with arm claudication, diminished radial pulses, and decreased blood pressure in the arms, suggestive of an occlusive arteritis. Arteriography revealed the typical findings of takayasu arteritis, which involved the brachial and axillary arteries but spared the aorta and its major branches. Changes in the patient's clinical course were correlated with sedimentation rate, angiography, and Duplex sonography.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
6/13. Takayasu's arteritis and pregnancy: a case of deleterious association.The association of pregnancy with Takayasu's arteritis is almost always uneventful. A case with high values of maternal blood pressure (BP) and severe intra-uterine growth retardation (IUGR), submitted to aggressive management with the delivery of a live fetus at 30 weeks, is presented.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |

Successful outcome of pregnancy in a subfertile patient with severe aortoarteritis (Takayasu's disease).This report describes the successful outcome of pregnancy in a 27-yr-old subfertile Chinese nullipara with severe Takayasu's disease. pregnancy was achieved following ovulation induction with clomiphene. blood pressure was controlled with propranalol and fetal growth was monitored by serial ultrasound fetal anthropometry. pregnancy was terminated at 38 weeks of pregnancy by elective caesarean section. A live female infant weighing 2420 g was delivered.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
8/13. Takayasu's arteritis in pregnancy. A report of 4 cases.Four cases of Takayasu's arteritis in association with pregnancy are described. These patients are at high risk of pregnancy hypertension. Measurement of the blood pressure in the arms may be impossible or unreliable and is often more accurately obtained in the legs.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
9/13. Systolic hypertension and cardiac mortality of Takayasu's aortoarteritis.Long-term observations of a 35-year-old woman who died from refractory congestive heart failure due to Takayasu's aortoarteritis are reported. Severe systolic hypertension was documented in the pre-pulseless phase. After the loss of all limb pulses, but relative sparing of carotid vessels, serial ophthalmodynamometric retinal pressures suggested that central aortic pressure remained high during her terminal cardiac illness. Postmortem pathologic examination showed a narrowed, severely atherosclerotic aorta with variable occlusions of all branch vessels. The loss of capacitance and volume of the aorta appears to be the cause of systolic hypertension and refractory pump failure of the left ventricle.- - - - - - - - - - ranking = 0.4keywords = pressure (Clic here for more details about this article) |
10/13. Tooth extractions and aortitis syndrome (Takayasu's disease).Several problems in tooth extraction in patients with aortitis syndrome are described and the following points are stressed. (1) The extractions of teeth should be done at nonactive period of the disease. (2) patients who reveal hyper- or impaired sensitivity of the carotid sinus should be positioned in the most relaxed way with no pressure and no stretch of the carotid sinus region. (3) Since no pulsation is present at any extremity in many patients, these patients should be carefully monitored during treatment. (4) Antibiotics before tooth extraction are necessary. (5) Tooth extractions should not alter an already unbalanced hemodynamic state to a more severe stage.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
