Pulmonary artery involvement in Takayasu's arteritis: diagnosis before pulmonary hypertension.

ABSTRACT: BACKGROUND:This study was performed to analyze the clinical manifestations, imaging features, and prognosis of Takayasu's arteritis (TA) with pulmonary arteritis (PA). METHODS:In total, 51 of 815 patients with TA were diagnosed with PA at the Peking Union Medical College Hospital from 1986 to 2015. The patients' medical records and radiographic data were retrospectively reviewed. RESULTS:The patients comprised 39 women and 12 men with a median age of 33?years (range, 14-67?years). The most common symptoms were dyspnea (70.6%), cough (66.7%), hemoptysis (47.1%), and chest pain (45.1%). Computed tomography (CT) pulmonary angiography, pulmonary arteriography, and pulmonary perfusion imaging showed pulmonary artery stenosis or occlusion in 44 patients. A total of 82.4% of patients had lung parenchyma lesions on CT scans, indirectly indicating pulmonary artery involvement. Additionally, 58.8% of patients had pulmonary hypertension (PH) by echocardiography. Compared with the PH group, the non-PH group was characterized by a shorter disease duration; more symptoms such as fever, chest pain, and hemoptysis; an increased erythrocyte sedimentation rate; and a higher incidence of subpleural wedge-shaped shadows on chest CT (P?

Echocardiographic characteristics of pulmonary artery involvement in Takayasu arteritis.

Project description:BackgroundUp to 50% patients with Takayasu arteritis have pulmonary artery involvement. Hence, the early identification of pulmonary artery involvement to facilitate prompt treatment is required.MethodsThis retrospective study was performed in patients diagnosed with Takayasu arteritis between January 2009 and January 2016. Pulmonary artery involvement was confirmed with computed tomographic pulmonary angiography. Images from transthoracic echocardiography in three windows (suprasternal right pulmonary artery long-axis view, parasternal aortic short-axis view, and subxiphoid view) were documented and analyzed.ResultsA total of 27 patients had Takayasu arteritis and pulmonary artery involvement. Characteristic changes identified by echocardiography included luminal medium-to-high echogenic signals, stenosis, and occlusion, as well as intimal thickening. Left pulmonary artery involvement was revealed in the parasternal aortic short-axis view. Right pulmonary artery involvement was best observed in the suprasternal right pulmonary artery long-axis view, with complementary views from the parasternal aortic short-axis and subxiphoid angles. Pulmonary trunk involvement was not observed in all three windows.ConclusionsTransthoracic echocardiography could be a useful noninvasive test to detect pulmonary artery involvement in patients with Takayasu arteritis.

Outcome measures for Takayasu's arteritis.

Project description:Purpose of reviewTakayasu's arteritis (TAK) is a large-vessel vasculitis with a chronic, indolent course affecting the aorta and its main branches. This review will describe the recent studies to develop validated outcome measures to assess TAK.Recent findingsTAK is traditionally assessed with a physician's global assessment including symptoms and signs of inflammation and vascular insufficiency, acute-phase reactants (APRs), and imaging including conventional digital subtraction angiography, computerized tomographic, and magnetic resonance angiography, and recently 18-FDG-PET. Recent attempts to develop a validated tool for disease assessment include the Indian Takayasu Clinical Activity Score (ITAS2010), which incorporates clinical signs and symptoms with APRs in a simplified and weighted adoption of the Birmingham Vasculitis Activity Score. Among biomarkers to assess clinical activity, pentraxin-3 is perhaps the most promising, but its validity and superiority against APRs in clinical practice need to be demonstrated. Patient-reported outcomes (PROs) are increasingly recognized as of substantial importance to measure in clinical trials; in addition to so-called 'generic' tools such as the SF-36 or measures of fatigue, disease-specific instruments would likely help capture aspects of TAK not measured by generic quality-of-life assessments or physician-based tools.SummaryAlthough outcome measures for TAK are not sufficiently validated, progress in the assessment of TAK is reflected in recent studies with new tools such as ITAS2010, new biomarkers, and a variety of PROs.

Magnetic resonance imaging in the diagnosis and follow up of Takayasu's arteritis in children.

Project description:BackgroundTakayasu's arteritis (TA) has a mortality rate of up to 40% in children. Because the clinical presentation of TA is often non-specific, accurate and prompt diagnosis depends on a high degree of awareness and appropriate laboratory and imaging studies.ObjectiveTo examine the use of advanced magnetic resonance imaging (MRI) in evaluating, gauging activity, and following the complications of TA.Methods and resultsT1 weighted, T2 weighted, contrast enhanced MR images, and MR angiograms of the chest and abdomen were obtained in three children (age range 11-14 years). The MRI studies confirmed the diagnosis of active TA and were repeated to evaluate response to treatment. Two patients showed complete resolution of lesions found on MRI at six and 12 months' follow up, while the third patient showed no significant improvement.ConclusionMRI can be used to help establish the initial diagnosis of TA in children, and it can also be used to monitor disease activity and to guide treatment.

CLINICAL PROFILE OF TAKAYASU'S ARTERITIS.

Project description:Thirty consecutive cases of Takayasu's arteritis (TA) admitted over a period of four years in a large referral hospital were analysed. The extent of aorta and its branches involvement was assessed by a Duplex Doppler study and aortography. The mean age of patients was 24.7 years with the male to female ratio of 1:1.2. The vascular involvement was, Type I (10%), Type II (40%) and Type III (50%). Renal artery (76.6%), Coeliac and superior mesenteric arteries (46.6%) and right common carotid artery (30%) were the commonly involved branches of aorta. Systemic features were seen in 25 per cent cases. Hypertension (83.3%), unequal pulses (80%) and arterial bruit (66.6%) were common clinical features. Stroke (20%), cardiac failure (10%) and renal failure(10%), were the complications seen. Hypertensive retinopathy was common, but Takayasu's retinopathy was not seen.

Distribution of arterial lesions in Takayasu's arteritis and giant cell arteritis.

Project description:To compare patterns of arteriographic lesions of the aorta and primary branches in patients with Takayasu's arteritis (TAK) and giant cell arteritis (GCA).Patients were selected from two North American cohorts of TAK and GCA. The frequency of arteriographic lesions was calculated for 15 large arteries. Cluster analysis was used to derive patterns of arterial disease in TAK versus GCA and in patients categorised by age at disease onset. Using latent class analysis, computer derived classification models based upon patterns of arterial disease were compared with traditional classification.Arteriographic lesions were identified in 145 patients with TAK and 62 patients with GCA. Cluster analysis demonstrated that arterial involvement was contiguous in the aorta and usually symmetric in paired branch vessels for TAK and GCA. There was significantly more left carotid (p=0.03) and mesenteric (p=0.02) artery disease in TAK and more left and right axillary (p<0.01) artery disease in GCA. Subclavian disease clustered asymmetrically in TAK and in patients ?55 years at disease onset and clustered symmetrically in GCA and patients >55 years at disease onset. Computer derived classification models distinguished TAK from GCA in two subgroups, defining 26% and 18% of the study sample; however, 56% of patients were classified into a subgroup that did not strongly differentiate between TAK and GCA.Strong similarities and subtle differences in the distribution of arterial disease were observed between TAK and GCA. These findings suggest that TAK and GCA may exist on a spectrum within the same disease.

Severe aortic regurgitation complicating Takayasu's arteritis.

Project description:We present an uncommon case of a 48-year-old female patient with symptomatic presentation of a severe aortic regurgitation with aneurysm of the ascending aorta and progressive dyspnea. Detailed investigation of laboratory tests and imaging identified Takayasu's arteritis (TA) as the underlying etiology. Computed tomography scan revealed complete occlusion of the right carotid artery as well as stenosis at the origins of left subclavian and vertebral arteries. In addition, cardiac magnetic resonance angiogram showed aneurysm at the proximal segment of right subclavian artery. Intervention with corticosteroids effectively diminished the need for immediate surgical intervention. Treating physicians should always consider differential diagnosis of TA in the presence of atypical clinical findings in all patients with cardiac problems especially when there is valve involvement.

Coronary-carotid artery collateral formation in Takayasu's arteritis: First reported case in the literature.

Project description:We present the first case report of coronary-carotid artery collateral formation in Takayasu's arteritis. There was a vasculitic involvement of both subclavian and carotid arteries with critical stenosis; cerebral perfusion was supported with collaterals arising from the mesenteric arteries and coronary artery. <Learning objective: A case of coronary-carotid artery collateral formation in Takayasu's arteritis is presented. Such an angiographic finding has not been reported previously, and this case could be the first description of coronary-carotid artery collaterals development. The learning objective of the article is to evaluate collateral circulation in Takayasu's arteritis from different vasculature including the coronary system.>.

Takayasu's arteritis: management of left main stem stenosis.

Project description:Takayasu arteritis is a chronic vasculitis involving the aorta and its main branches, the pulmonary arteries, and the coronary tree, and needs to be considered in a young patient with angina, in particular when pulses are absent. This case illustrates the limitations of exercise testing in diagnosing the extent of coronary artery disease and the risks associated with coronary angiography in patients with inflammatory disease in the left main stem coronary artery. It also highlights the novel use of non-invasive scanning with positron emission tomography using 18-fluorodeoxyglucose in assessing remission from this disease. Revascularisation was performed with percutaneous transluminal coronary angioplasty and stenting as an emergency procedure, but treatment of the restenosis with directional atherectomy was based on a review of the available literature. The lymphocytic alveolitis seen in this patient has not been previously described in Takayasu's disease.
