The authors report a 7 year follow-up of Takayasu's arteritis (TA) type III, group 1, in a young Italian woman. At diagnosis, at the age of 25, the echotomographic and angiographic studies showed narrow subclavian arteries, narrow abdominal aorta (diameter of 0.6-0.8 cm) below the renal arteries, stenotic left common carotid and renal arteries, and occluded upper mesenteric artery. With steroid therapy, (prednisone 50 mg/day per os), the erythrocyte sedimentation rate (ESR) normalized within 12 days. With a maintenance dosage of 7.5 mg/day per os, the patient achieved remission as documented by the absence of symptoms, the persistent normalization of ESR, and the improving of the diameter of the abdominal aorta (1.3-1.4 cm). On steroid therapy, the patient had a normal pregnancy and delivered a healthy baby girl. The disease has been stable for seven years. Recently, diabetes mellitus occurred and it has been treated with insulin therapy. The rising of ESR after tapering of steroid therapy (prednisone 5 mg per os on alternate days) suggests an alternative treatment with a cytotoxic agent. 相似文献

Autopsy findings of widespread thrombosis and necrotizing arteritis of the liver in a 69-year-old woman who had clinical symptoms suggesting those of temporal (giant cell) arteritis were presented. The lesion of the temporal artery was not of temporal arteritis but of thrombosis, part of widespread thrombosis, which occurred in the small arteries having hypertensive arteriolopathy. This case also had an arteritis of the liver resembling polyarteritis nodosa (PN). The pathologic processes demonstrated in this case suggested that the temporal arteritis-like symptoms may be brought about by occlusion of the temporal artery. Temporal arteritis is a nonfatal and self-limited disease and little information has been obtained from autopsy material. Accordingly, it is necessary to collect autopsy cases of temporal arteritis to investigate this disease through observations of whole bodies. Recently we examined a case which appeared clinically having symptoms of temporal arteritis, but the autopsy revealed that the symptoms were not brought about by temporal arteritis but by thrombosis of the temporal artery. It is the purpose of this paper to present this case and to discuss some problems concerning genesis of symptoms of temporal arteritis. 相似文献

A 39-years-old woman with Takayasu's arteritis confirmed by histological examination was admitted in our hospital because of angina pectoris. Selective coronary arteriograms reveled a 90% isolated stenosis in the right coronary ostium. The patient underwent a right coronary artery bypass grafting using the saphenious vein. The post operative clinical course was uncomplicated. On follow-up over 14 months the patient has been completely free from anginal chest-pain. 相似文献

Takayasu arteritis was diagnosed in two children, a 15-year-old girl and a 10-year-old boy. The girl had suffered from fatigue, malaise, abdominal pain and weight loss for several months, but no clear cause could be found. A few weeks later, when a blood pressure of 222/155 mmHg was measured, the possibility of renal artery stenosis was considered and imaging studies revealed indications for Takayasu's disease. The patient was given methylprednisolone followed by a combination of prednisone and, initially, cyclophosphamide, later methotrexate. This resulted in a clinical remission of the inflammatory process. The boy presented with increasing fatigue and variable episodes of fever. After 3 years, sarcoidosis or Castleman's disease were considered. Imaging studies revealed aortic stenosis. He underwent stenting of the involved vessel segment. Takayasu arteritis is a chronic vasculitis of unknown origin, affecting mainly the aorta and its main branches. As a result of the inflammation, stenosis, occlusion or dilatation of the involved vessels may occur and cause a wide range of symptoms. Especially in the early phase, the symptoms often are non-specific. One should look for hypertension, blood pressure differences between the two arms, decreased peripheral pulsation or bruits over the aorta and its major branches. Radiological examination may consist ofangiography, magnetic resonance imaging or CT-scans. Treatment consists of corticosteroids and other immunosuppressants, such as cyclophosphamide, methotrexate, azathioprine, and antagonists of tumour-necrosis factor alpha. In addition, balloon dilatation or stenting is often necessary. 相似文献

Takayasu''s arteritis is a large vessel vasculitis that can be a challenging diagnosis to make and has a varied clinical presentation. Management largely depends on affected vessel disease severity and individual patient considerations. The diagnosis must be considered in a young patient with large vessel aneurysms. We present a case of a 30 year-old woman of Pacific Islander descent who presented to the Tripler Army medical Center Vascular Surgery Department in Honolulu, Hawai‘i seeking repair of her abdominal aortic and renal artery aneurysms prior to conception.A 30 year-old Pacific Islander woman with a history of a saccular abdominal aortic aneurysm and renal artery aneurysms presented to our clinic seeking vascular surgery consultation prior to a planned pregnancy. She had a renal artery stent placed at an outside institution for hypertension. She met the diagnosis of Takayasu''s arteritis by Sharma''s criteria. Physical exam was significant for a palpable, pulsatile, abdominal mass and CT angiography revealed a saccular irregular-appearing infra-renal abdominal aortic aneurysm, extending to the aortic bifurcation, with a maximum diameter of 3.3 cm. A right renal artery aneurysm was also identified proximally, contiguous with the aorta, with a maximal transverse diameter of 1.7 cm. The patient underwent a supraceliac bypass to the right renal artery with a 7mm Dacron graft, as well as excision of the right renal artery aneurysm. The abdominal aortic aneurysm was replaced using a Hemashield Dacron bifurcated 14mm x 7mm bypass graft. Intraoperative measurements of the renal artery aneurysm were 1.5 x 1.5 cm and the saccular appearing distal abdominal aortic aneurysm measured 3.6 x 3.3cm. The patient was discharged from the hospital 7 days post-operatively. At 1-year follow up, CT scan of the abdominal aorta revealed the repair was without any evidence of aneurysm formation, anastomotic pseudoaneurysm formation, or areas of stenosis. She has remained normotensive with a normal serum creatinine 18 months after her repair. She has since delivered her second child.It is rare for Takayasu''s arteritis to present with aneurysmal disease. It is much more common to present with stenosis or occlusion. It has yet to be proven that Takayasu''s truly has a higher incidence in those of Asian descent. Takayasu''s can be a difficult diagnosis to make but can be aided with the use of Sharma''s criteria. Our particular patient posed unique considerations on the effects of the physiology of pregnancy on her aneurysms and repair.Managing the active phases of disease is imperative, and though medical management is first line, surgical intervention may be necessary. Surgical intervention should be performed in a quiescent period of disease if possible given that biological inflammation at the time of intervention increases the complication rate. Repair of aneurysmal disease in a young female should also be considered prior to pregnancy. 相似文献

A 77-year-old woman was admitted because of progressive vertigo, nausea and a dysarthric speech disorder. The patient's history of diabetes mellitus, hypertension and hypercholesterolaemia, and the finding of murmurs over peripheral arteries at physical examination led to a presumptive diagnosis of cerebellar ischaemia in the context of generalized atherosclerosis. However, the diagnosis was revised when bilateral cerebellar infarction was demonstrated radiologically, and a biopsy of a temporal artery revealed giant cell arteritis. Despite treatment with prednisone (60 mg daily) the patient's neurological condition deteriorated, and she succumbed several months later to pneumonia. The case illustrates the pitfalls in the diagnostic approach of elderly patients with multiple pathology and it also emphasizes that in an elderly person with high erythrocyte sedimentation rate (> 100 mm in the first hour) temporal arteritis should be ruled out as soon as possible to prevent further neurological damage. 相似文献

Encephalopathy, recurrent occlusion of retinal arteries and hearing loss comprise the clinical picture of Susac's syndrome. The correct diagnosis is frequently missed because of incomplete clinical signs or negligence of previous symptoms. Early diagnosis and treatment can halt the progression and prevent permanent disability. METHODS: Here, we describe a Hungarian case and review the clinical characteristics, diagnostic procedures and current concepts of therapy. RESULTS: A 30-year-old female was admitted to our neurology department because of change in her personality, apathy, and difficulty in concentration. Brain MRI indicated multiple hyperintense T2-weighted lesions including cerebellum and corpus callosum. Protein content of the CSF was markedly elevated. The recurrent bilateral loss of vision and hearing along with migraine in her previous 2,5-year-long medical history suggested Susac's syndrome. Fundoscopy and fluorescein angiography indicated multiple occlusions of the retinal arteries, audiography revealed bilateral hearing loss. Systemic autoimmune and connective tissue diseases and thrombophilia were excluded. The markedly elevated protein in the cerebrospinal fluid supported Susac's syndrome. Chronic treatment with methylprednisolone resulted in remission of clinical signs. DISCUSSION: Consideration of multiple clinical signs is an important key to the diagnosis of rare clinical entities like Susac's syndrome. 相似文献

The authors report on their results with local intraarterial thrombolysis in four patients. PATIENTS: Three patients suffered from vertebrobasilar artery occlusion, and one from carotid-T occlusion. All were treated with local intraarterial thrombolysis by a joint team of neurologist, neuroanaesthesist and interventional neuroradiologist in the stroke-department of St. Stephen Municipal Hospital in collaboration with National Institute of Neurosurgery. Selection of patients suitable for successful intraarterial thrombolysis has to be done in the neurological department with help of ultrasound and neurological examination and CT scan. Patients were transferred to the therapeutic angiosuit and interventional treatment was initiated immediately upon establishing the diagnosis. At least one million units of urokinase was infused directly into the embolus in each case. RESULTS: Complete recanalisation was achieved in three of the four cases. That was associated with full recovery in two patients, in whom good collateral circulation and no signs of atherosclerotic lesions were found prior to treatment. Another patients has died despite of full recanalisation of the basilar artery. One patient survived after partial recanalisation of bilateral vertebral artery occlusion with mild residual tetraparesis. CONCLUSION: Local intraarterial thrombolysis is effective and is associated with good clinical outcome in properly selected patients. Careful and accurate ultrasound diagnostics of the site of occlusion plays a significant role in proper patient selection. Although difficult, acute intraarterial thrombolysis can be organized in a timely fashion even utilizing the required facilities in two different institutions, providing that all efforts is being made by each party for the fast diagnosis and treatment initiation. 相似文献

The present study was designed to determine whether norepinephrine (NE) mediate endothelium-dependent relaxations in arteries
of the pulmonary vasculature of cold-acclimated rats. Twenty male Sprague-Dawley rats comprising two groups (Cold-acclimated
for 12 weeks at 6°C, CA; Warm-acclimated for 12 weeks at 24 °C, WA) were used. After anesthesia, the pulmonary artery (4 mm
long) was isolated. Pulmonary artery with and without endothelium were suspended for isometric force measurements in a buffered
salt solution. The doseresponse relations for the vascular responses to the isolated pulmonary artery to norepinephrine (NE),
phenylephrine (PE) and acetylcholine (Ach) were determined and compared in the CA group and the WA group. In the CA group,
the vascular sensitivities to NE and PE-induced contraction in the pulmonary artery was significantly lowered than that in
the WA group. NE and PE-induced contractions were significandy greater in endotheliumdenuded compared with endothelium-intact
arteries. These differences of contraction responses to NE and PE between arteries with widiout endothelium were significantly
greater in the CA group than in the WA group. There was no significant difference between the pulmonary arterial response
to Ach in the CA group and that in the WA group. Our data suggest that chronic exposure to cold show decreased NE and PE-induced
contraction responses in isolated pulmonary arteries and may decrease NE-induced contraction responses due to enhancing NE-induced
endodielium derived relaxing factor release via up-regulating endothelial α-adrenoceptors. 相似文献

This study was undertaken to clarify whether pulmonary hypertension is a useful marker for underlying obstructive sleep apnea in patients with edema. Twenty-eight ambulatory adults with bilateral leg edema and a normal echocardiogram were enrolled. Sixteen subjects had pulmonary hypertension, and 12 subjects had normal pulmonary artery pressures. Spirometry, pulse oximetry on room air, and polysomnography were obtained for each subject. Ten of 16 (63%) pulmonary hypertension subjects and 9 of 12 (75%) nonpulmonary hypertension subjects had obstructive sleep apnea (P =.48). Eleven of 16 (69%) pulmonary hypertension subjects and 11 of 12 (92%) nonpulmonary hypertension subjects were obese (P =.20). If these results are generalizable, obstructive sleep apnea is frequently associated with bilateral leg edema and obesity, regardless of the presence of pulmonary hypertension. Thus, especially in obese patients, bilateral leg edema may be a useful clinical marker for underlying obstructive sleep apnea. 相似文献

The first population-based incident case-control study of temporal arteritis (TA) in the US was conducted using the unique data resources of the Rochester Epidemiology Project. During the period 1950-1985, 88 newly diagnosed cases of biopsy-proven TA were identified among residents of Olmsted County, Minnesota. Cases were each matched to four Olmsted County community controls on age, sex and duration of community medical record. Odds ratios (OR) were calculated for marital status, education, Quetelet index, pregnancy, age at menopause, thyroid disease, diabetes, smoking, hypertension, angina, myocardial infarction, peripheral vascular disease, and stroke. Multivariable conditional logistic regression analysis identified statistically significant adjusted OR for smoking (2.3, 95% CI = 1.3-4.1). Elevated ORs which were not statistically significant were noted for angina, myocardial infarction, and peripheral vascular disease. These data suggest that TA and arteriosclerosis may share a common causal pathway. Alternatively, histopathological misclassification of temporal artery biopsies may have resulted in the observed association. Due to the limited power of this population-based study, multicentre collaboration should be encouraged to more precisely define the epidemiology of TA. 相似文献
