    Full Text Available Context: Syphilitic aortitis has been relegated to the category of rare cardiovascular disease or a "medical curiosity" in the west. The same situation may not exist in developing countries due to the stigmata that continue to remain attached to sexually-transmitted diseases in general. Aims: To study the prevalence of syphilitic aortitis among autopsied non-atherosclerotic aortic diseases encountered in a span of 15 years. Settings and Design: Retrospective, autopsy-based study. Materials and Methods: Among 187 cases of non-atherosclerotic diseases of the aorta, 44 had been diagnosed as syphilitic aortitis on the basis of the pathological features and serology. The demographic details and modes of clinical presentation were retrieved from the health records. Depending on the presence of complicating lesions, the cases were classified as uncomplicated or complicated aortitis. Results: The 44 cases of syphilitic aortitis formed 23.5 % of the non-atherosclerotic aortic diseases. They were predominantly seen in males in the fifth decade, who often presented with valvular regurgitation, aneurysmal disease or myocardial ischemia; 13.6 % of patients were asymptomatic. Blood VDRL results were available in 19 patients; 84.2 % were positive. Concomitant involvement of the ascending, transverse and descending thoracic was seen in 45.5 % of cases. None had uncomplicated aortitis. Complications in the form of aortic regurgitation (72.7 %, coronary ostial stenosis (59 % and aneurysms (59 % frequently coexisted. Thirty-five aneurysms were present in 59 %, chiefly involving the aorta. Conclusions: We found syphilitic aortitis to be a common cause of aortitis at autopsy. Diagnosis should be made with the help of characteristic pathological features correlated to the clinical context and appropriate serological tests.

    Two cases of aortitis associated with the presence of antiphospholipid antibodies (APAs) are reported. Only CT and MR imaging were able to show these unusual form of aortitis preferentially affecting the outer aortic tunics. We conclude that aortitis could be a new manifestation of primary antiphospholipid syndrome (APS) and the initial pathological process before the development of aortic thrombosis, reported as a classical complication of APS.

    Full Text Available In the antibiotic era, aortic aneurysm is a rare complication of syphilis, what makes the diagnostic assumption even more difficult. Nonetheless, this condition should be suspected in patients with aortic aneurysm. Reports of aortic dissection complicating syphilitic aortitis have been distinctly rare in the literature, and their cause-effect relationship has not been definitely established. In this case report, we present a 62-year-old woman with aortic aneurysm and dissection associated with an unexpected diagnosis of syphilitic aortitis.

    Clostridium septicum ( C. septicum ) aortitis is a rare condition frequently associated with colon adenocarcinoma and carries a poor prognosis. We report the case of a 66-year-old man who presented with abdominal pain, blood in the stool, fever and chills. Laboratory tests were significant for leukocytosis and microcytic anemia. Abdominal imaging revealed a right colon mass and aortitis. Colonoscopy confirmed the right colon mass and also discovered a rectal mass, both adenocarcinomas. Treatment consisted of antibiotics, aortic repair, right hemi-colectomy and later trans-anal excision of the rectal mass. Blood cultures and the aortic specimen grew C. septicum . The patient improved and was doing well in follow up.

    Full Text Available Abstract Aortitis may be due to infectious and non-infectious causes. We observed aortitis, associated with glaucoma, thyroiditis, pericarditis, pleural effusion and neuropathy in a 63-years old woman. Despite antibiotic therapy, inflammatory signs persisted and resolved only after initiation of glucocorticoid therapy. Increasing aortic ectasia necessitated resection of the ascending aorta and implantation of a Vascutek 30 mm prosthesis. Histologically a granulomatous aortitis was diagnosed. Since all other possible causes were excluded, an immunological mechanism of the aortitis is suspected and possible triggering factors are discussed.

    IgG4 aortitis is one of the entities seen in the spectrum of IgG4-related disease (IgG4-RD). It is characterized by serologic (elevated serum IgG4) and histologic features including a lymphoplasmacytic infiltrate with increased numbers of IgG4-positive plasma cells, storiform fibrosis and obliterative phlebitis. Some studies have described a correlation between infections and IgG4 aortitis. We describe a patient with an aneurysm of the infrarenal descending abdominal aorta with features of IgG4-RD, as well as culture evidence of Streptococcus sanguis.

    1984-01-01

    A 45-year-old female was admitted to our hospital with complaints of anemia, hypertension, and a dull, throbbing pain in the right side of the neck. On physical examination, a pulsating tumor in the right side of the neck and a ''to-and-fro'' murmur at the right 2nd intercostal space were noted. Laboratory tests revealed ESR 90 mm/hour and CRP 5+. Digital subtraction angiography (DSA) showed an aneurysm distal to the narrowing of the right common carotid artery, in addition to winding and narrowing of the right vertebral and the left common carotid arteries. These findings are typical of Type I aortitis syndrome. Aortogram showed aortic regurgitation (AR). Furthermore, we found the presence of HLA Bw52 and a conspicuous increase of tromboxane B 2 . Treatment involving a combination of prednisolone, azathioprine and estriol was effective, resulting in marked improvement of the patient's general condition as well as laboratory test results. In cases of aortitis syndrome combined with an aneurysm of a large artery and AR, direct opacification of the aorta with a catheter is occasionally hazardous and is difficult to perform repeatedly. DSA is useful in such circumstances because it can be performed repeatedly with little risk and it offers an image as clear as these obtained by direct injection of contrast medium in the aorta.

    Vasculitides are heterogenic group of autoimmune connective tissue diseases which often present difficulties in early diagnosing. Giant cell arteritis is vasculitis of large and medium arteries. It predominantly presents with symptoms of affection of the external carotid artery branches. Furthermore, the only symptoms can be constitutional. In clinical practice, vasculitides are sometimes considered as paraneoplastic, but no definite association with malignancies has been established and the mechanisms are still debated. The gold standard for diagnosing giant cell arteritis is a positive temporal artery biopsy, but the results can often be false negative. Additionally, more than half of the patients have aorta and its main branches affected. Considering aforementioned, imaging studies are essential in confirming large-vessel vasculitis, amongst which is highly sensitive PET/CT. We present the case of a 70-year-old female patient with constitutional symptoms and elevated sedimentation rate. After extensive diagnostic tests, she was admitted to our Rheumatology unit. Aortitis of the abdominal aorta has been confirmed by PET/CT and after the introduction of glucocorticoids the disease soon went into clinical and laboratory remission. Shortly after aortitis has been diagnosed, lung carcinoma was revealed of which the patient died. At the time of the comprehensive diagnostics, there was no reasonable doubt for underlying malignoma. To the best of our knowledge, there are no recent publications concerning giant cell arteritis and neoplastic processes in the context of up-to-date non-invasive diagnostic methods (i.e. PET/CT). In the light of previous research results, we underline that the sensitivity of PET/CT is not satisfactory when estimating cancer dissemination in non-enlarged lymph nodes and that its value can at times be overestimated.

    Aortitis is a general term that refers to all conditions involving an inflammation of the aortic wall. This case report describes the surgical approach of a patient with infectious and symptomatic aortitis caused by the rare vector Prevotella intermedia. A 44-year old male patient was admitted with fever and general discomfort after a period of sore throat in a non-teaching hospital. After two weeks he developed acute abdominal and back pain accompanied by sweating and elevated infection parameters. Computed tomography angiography revealed atherosclerotic changes of the infrarenal aorta with a locally contained rupture of the aorta alongside peri-aortal signs of inflammation (and aortitis aspects). An urgent aortic reconstruction was performed according to Nevelsteen. The blood cultures turned out positive for Prevotella intermedia. Postoperatively the patient received antibiotics for six weeks. The patient recovered uneventful from this infection and surgical procedure. A complicated and acute aortitis is a rare but potentially life-threatening disease. The aetiology can be ordered into two main groups; inflammatory and infectious. Diagnosis is based upon symptoms, biochemical values, microbiological results and imaging modalities. Treatment depends on aetiology and should be discussed in an experienced multidisciplinary setting. Infectious aortitis should be treated with antibiotics for at least six weeks with close monitoring of the patient's clinic and biochemical values, even after surgery. Prevotella intermedia is a rare causative agent for aortitis. Acute aortitis is a challenging clinical entity which should be managed in an equipped medical center by an experienced multidisciplinary team. Copyright © 2017 The Authors.

    Full Text Available Behcet's aortitis is a rare, but one of the most severe complications of Behcet's disease. We report a 24-year-old woman who was noted initially to have aortitis and severe aortic regurgitation caused by Behcet's disease. After receiving aortic valve replacement, aortoplasty and immunosuppressant therapy, her condition became stationary. As far as we are aware, she is the youngest case that has undergone surgery. The early onset of hemodynamic decompensation is considered to be related to delay in diagnosis and lack of steroid treatment.

    The aim of this study was to evaluate the contribution of semiquantitative analysis of 180-min {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT images for the assessment of aortitis in cases of suspected large vessel vasculitis (LVV) and to establish a threshold index for application in the clinical setting. This prospective study included 43 patients (mean age 67.5 ± 12.9 years) with suspicion of LVV (25 with a final diagnosis of aortitis). {sup 18}F-FDG PET/CT scan was acquired 180 min after injection of 7 MBq/kg of {sup 18}F-FDG. A semiquantitative analysis was performed calculating the aortic wall maximum standardized uptake value (SUV{sub max}) (T), the lumen SUV{sub max} (B) and the target to background ratio (TBR). These results were also compared with those obtained in a control population. The mean aortic wall SUV{sub max} was 2.00 ± 0.62 for patients with aortitis and 1.45 ± 0.31 for patients without aortitis (p < 0.0001). The TBR was 1.66 ± 0.26 for patients with aortitis and 1.24 ± 0.08 for patients without aortitis (p < 0.0001). The differences were also statistically significant when the patients with aortitis and controls were compared. Receiver-operating characteristic (ROC) analysis revealed that the area under the curve was greater for the TBR than for the aortic wall SUV{sub max} (0.997 vs 0.871). The highest sensitivity and specificity was obtained for a TBR of 1.34 (sensitivity 100 %, specificity 94.4 %). Semiquantitative analysis of PET/CT images acquired 180 min after {sup 18}F-FDG injection and the TBR index of 1.34 show very high accuracy and, therefore, are strongly recommended for the diagnosis of aortitis in the clinical setting.

    The aim of the study was to compare epidemiological data, clinical findings and results of investigations in patients with isolated aortitis and those with giant cell arteritis (GCA) to establish whether patients with isolated aortitis differ from those with GCA. We reviewed the medical notes of all patients consecutively seen in two Rheumatology centres in the last two decades with a suspicion of GCA, searching for cases characterised by abnormal [18F] fluorodeoxyglucose (FDG) PET uptake of the aorta. 'Isolated aortitis' was defined as increased FDG uptake in the aorta not explained by atherosclerosis in the absence of FDG uptake in other large vessels. Comparing the epidemiological and clinical data of patients with isolated arteritis with those with GCA, we observed many statistical significant differences. First of all, the male/female ratio was reversed, with a predominant male involvement in isolated arteritis. Moreover, the mean age of patients with isolated arteritis was significantly lower than that of GCA patients (62 vs. 78.4 yrs; psides of the same coin.

    Takayasu aortitis (TA) is a chronic inflammatory and fibrotic vasculitis of large- and medium-sized arteries. Early stages of the disease show a panarteritis and inflammatory wall thickening of the aorta and its branches, whereas advanced (fibrotic) stages comprise stenosis, aneurismatic transformation and occlusion. Magnetic resonance imaging visualises early-stage disease with high accuracy and is considered to be the method of choice in the diagnosis of TA. The aim of this article is the detailed comparison of FDG-PET performed with a hybrid camera and MR imaging in five patients with early TA. Five patients (median age 60 years) were enrolled during an ongoing prospective study on [18F]2'-deoxy-2-fluoro-D-glucose (FDG) hybrid camera PET in patients with fever of unknown origin (FUO). These patients underwent MR imaging after establishing the diagnosis of TA. Abnormal FDG uptake in the wall of the aorta was noted in all patients. The bracheocephalic artery and the common carotid arteries were visualized in 3 cases. Increased uptake of the subclavian artery was found in 3 patients and in 4 patients pathological uptake was noted in the ilio-femoral vessels. Of 34 vascular regions studied, 26 (76%) showed elevated FDG uptake. On transversal MR images vessel wall thickening and contrast enhancement of the thoracic aorta was found in 4 patients (ascending aorta/aortic arch: n=2; descending aorta: n=3; abdominal aorta: n=1). Additionally, vessel wall pathologies of the subclavian and the common carotid arteries could be shown in 1 patient and in another patient in the ilio-femoral arteries. No abnormalities were found using contrast-enhanced MR angiography. Of 28 vascular regions studied, 9 (32%) showed vasculitis on MRI. The FDG-PET is a suitable whole-body screening method in the primary diagnosis of early TA, especially in those cases with early disease that present with uncharacteristic symptoms such as FUO. Both MRI and MRA remain indispensable in the exact

    The aim of this prospective study was to compare fluorine-18 fluorodeoxyglucose ([{sup 18}F]FDG) positron emission tomography (PET) with magnetic resonance imaging (MRI) in patients with early aortitis, at the time of initial diagnosis and during immunosuppressive therapy. The study population consisted of 15 patients (nine females and six males; median age 62 years, range 26-76 years) who presented with fever of unknown origin or an elevated erythrocyte sedimentation rate or elevated C-reactive protein and who showed pathological aortic [{sup 18}F]FDG uptake. Fourteen of these patients had features of early giant cell arteritis (GCA), while one had features of early Takayasu arteritis. During follow-up, seven PET scans were performed in six patients with GCA 4-30 months (median 19 months) after starting immunosuppressive medication. The results of [{sup 18}F]FDG imaging were compared with the results of MRI at initial evaluation and during follow-up and with the clinical findings. At baseline, abnormal [{sup 18}F]FDG uptake was present in 59/104 (56%) of the vascular regions studied in 15 patients. Seven follow-up PET studies were performed in six patients. Of 30 regions with initial pathological uptake in these patients, 24 (80%) showed normalisation of uptake during follow-up. Normalisation of [{sup 18}F]FDG uptake correlated with clinical improvement and with normalisation of the laboratory findings. All except one of the patients with positive aortic [{sup 18}F]FDG uptake were investigated with MRI and MRA. Thirteen of these 14 patients showed inflammation in at least one vascular region. Of 76 vascular regions studied, 41 (53%) showed vasculitis on MRI. Of 76 vascular regions studied with both PET and MRI, 47 were concordantly positive or negative on both modalities, 11 were positive on MRI only and 18 were positive on PET only. MRI was performed during follow-up in six patients: of 17 regions with inflammatory changes, 15 regions remained unchanged and two

    Syphilis infection persists globally contributing to preventable and treatable morbidity and mortality. How extensive early syphilis disseminates is unknown. To better understand the relationship between early syphilis infection and inflammation over time, our study enrolled six individuals recently infected with syphilis for sequential positron emission tomography (PET) scans. We evaluated a case series of six individuals with high syphilis titres (two secondary, two early latent and two latent, unknown duration, but with high titre) who received sequential PET scans to assess inflammation over time and its response to treatment. At time of PET scan, four of the six individuals were co-infected with HIV. One of the four was not on antiretroviral therapy and three of the four were not virally suppressed (viral load of >400 copies/mL). Baseline rapid plasma reagin (RPR) titres ranged from 1:64 to 1:256 (four of the six participants had prior non-reactive RPR results). Five of the six participants had mild to intense hypermetabolic PET scan activity consistent with cervical (n=5), axillary (n=4), inguinal (n=5) and retroperitoneal (n=1) adenopathy. Mild hypermetabolic activity in the thoracic aortic wall, suggesting aortitis, was present among the same five participants and resolved within 30 days for four of the five participants and 60 days for the other participant. However, widespread lymphadenopathy remained present in PET scans up to 3 months following treatment in two participants. We did not find any abnormal PET scan activity of the central nervous system. We found abnormal aortic wall PET scan activity suggesting aortitis to be common in a case series of patients with early syphilis. In research settings, PET scans may be a sensitive tool to monitor inflammation associated with syphilis. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    this article reports a case of a seven-year girl who presented with severe dilated cardiomyopathy (DCM) associated with a large thrombus in the left ventricle (LV). She had a long segment stenosis of the lower thoracic descending aorta, possibly due to non-specific aortitis and underwent successful stent angioplasty. The LV thrombus resolved after heparin without sequelae.

  8. Thoracic vasculitis presenting as surgical problems.

    We present four patients with vasculitis manifesting with unusual clinical or pathological features, generating surgical problems. Two cases presented with pulmonary hypertension, with investigations and radiological evidence prompting clinical suspicion of pulmonary thrombo-embolic disease. First case, with an antecedant history of Wegener\\'s granulomatosis (WG), demonstrated following "embolectomy", WG involving the large pulmonary elastic arteries. The second case of inoperable "pulmonary thrombo-embolic disease" was subsequently found at limited post mortem to have giant cell arteritis, which affected widespread small peripheral pulmonary arterial vessels. The other two cases were of aortitis occurring in the background of immune-mediated disease, which had been treated with aggressive immunosuppression regimens. The first of these was a case of Cogan\\'s syndrome complicated by descending aortitis, a rarely reported phenomenon, with co-existent acute endocarditis of the aortic valve leaflets. Most cases of endocarditis in this context occur secondary to and in continuity with ascending aortitis. That this case, and a case of ascending aortitis occurring in the context of relapsing polychondritis occurred in the face of aggressive immunosuppression with an apparent clinical response, underscores the need to not accept a clinical picture at face value. This has implications for clinical management, particularly in the follow-up of surgical prosthetic devices such as grafts which may be used in these cases. All four cases emphasise the continued importance of histology and the post-mortem examination in elucidating previously undetected or unsuspected disease.

    From 1962 to 1970 about 200 abdominal aortographies were performed in Department of Radiology of National Medical Center, Seoul, Korea, with percutaneous retrograde seldinger catheterization technique. The 200 cases of the abdominal aortography were analyzed as followings. 1) The sex ratio of all patients was 105 (52.5%) males to 95 (47.5%) females. And high incidence was noted in middle age group. (46 patients were from 30 years to 40 years of age) 2) Radiological findings were grouped as 62 (31%) vascular lesion, 113 (56.5%) visceral or other expanding lesions and 29 (14.5%) angiographically nonspecific findings. Total is over 200 due to double lesions in 4 patients. 3) The 62 vascular lesions were composed of 40 aortitis, 28 renal hypertension etc. a) The 40 aortitis was divided into 25 artherosclerotic and 15 nonspecific. The 15 nonspecific aortitis revealed segmental narrowing (2-4 cm) with collaterals. b) In 28 renal hypertension, 17 cases were combined with aortitis, but not in 11 cases (Pure renal hypertension), and 19 cases were unilateral. 4) The highest incidence in 113 (56.5%) visceral or other expanding lesions, was renal lesions (88 cases), and other lesions, such as 12 retroperitoneal masses, 9 liver and pancreatic masses were also noted. The 88 renal lesions were composed of 37 renal tbc, 17 hydronephrosis (excluding tbc hydro), Tumors, 10 cyst etc. a) The most significant findings of renal tuberculosis in renal arteriogrpahy was rarefaction of contrast staining in involved area which was noted in 32 cases (87%) out of 37 renal Tuberculosis. b) All 12 hypernephroma, 1 wilm's tumor, metastaic tumor from fibromyomata uteri revealed pathological vessels and tumor stainings, however these findings were not noted in 2 ureteral carcinoma involving renal pelvis. 5) No permanent complications arose after abdominal aortography.

    Aortic aneurysm has been reported to be the dominant cause of primary iliac-enteric fistula (IEF) in >70% of cases [1]; other less common causes of primary IEF include peptic ulcer, primary aortitis, pancreatic pseudocyst, or neoplastic erosion into an adjacent artery [2, 3]. We describe an unusual case of IEF managed with a staged approach using an endovascular stent-graft as a “bridge” in the emergency setting to optimize the next elective definitive excision of the lesion.

  13. Determinants of Vessel Targeting in Vasculitis

    2004-01-01

    Full Text Available Studies of autoimmune diseases have not yet elucidated why certain organs or vessels become the objects of injury while others are spared. This paper will explore the hypothesis that important differences exist in regions of the aorta that determine vulnerability to diseases, such as atherosclerosis, aortitis, giant cell arteritis and Takayasu's disease. The reader is invited to reassess; (1 whether the aorta is indeed a single homogeneous structure, and (2 whether the initial stage of aortitis (and indeed other diseases considered “autoimmune” may be primarily due to acquired alterations of substrate, that influence unique immune profiles, which by themselves may not be pathogenic. Disease susceptibility and patterns are influenced by many factors that are inborn and acquired. Examples include genetic background, gender, ethnicity, aging, prior and concomitant illnesses, habits, diet, toxin and environmental exposures. Studies of vascular diseases must assess how such variables may affect regional differences in endothelial cells, subendothelial matrix, vascular smooth muscle and the response of each to a variety of stimuli.

    Abstract Objectives: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition that can affect multiple organs and lead to tumefactive, tissue-destructive lesions. Reports have described inflammatory aortitis and periaortitis, the latter in the setting of retroperitoneal fibrosis (RPF), but have not distinguished adequately between these 2 manifestations. The frequency, radiologic features, and response of vascular complications to B cell depletion remain poorly defined. We describe the clinical features, radiology findings, and treatment response in a cohort of 36 patients with IgG4-RD affecting large blood vessels. Methods: Clinical records of all patients diagnosed with IgG4-RD in our center were reviewed. All radiologic studies were reviewed. We distinguished between primary large blood vessel inflammation and secondary vascular involvement. Primary involvement was defined as inflammation in the blood vessel wall as a principal focus of disease. Secondary vascular involvement was defined as disease caused by the effects of adjacent inflammation on the blood vessel wall. Results: Of the 160 IgG4-RD patients in this cohort, 36 (22.5%) had large-vessel involvement. The mean age at disease onset of the patients with large-vessel IgG4-RD was 54.6 years. Twenty-eight patients (78%) were male and 8 (22%) were female. Thirteen patients (36%) had primary IgG4-related vasculitis and aortitis with aneurysm formation comprised the most common manifestation. This affected 5.6% of the entire IgG4-RD cohort and was observed in the thoracic aorta in 8 patients, the abdominal aorta in 4, and both the thoracic and abdominal aorta in 3. Three of these aneurysms were complicated by aortic dissection or contained perforation. Periaortitis secondary to RPF accounted for 27 of 29 patients (93%) of secondary vascular involvement by IgG4-RD. Only 5 patients demonstrated evidence of both primary and secondary blood vessel involvement. Of those treated with

    One hundred fifty patients having pulmonary disease underwent pulmonary scintigraphy sequentially with sup(99m)Tc-MAA and sup(81m)Kr gases. Scintigrams of matched defect were obtained from 113 (75.3%) of the 150 patients, considered to be nonspecific universal pattern of a pulmonary disease. Scintigrams of mismatched defect (absent perfusion and homogeneous ventilation) were obtained from 20 patients (13.3%), including 6 with lung carcinoma, 3 with pulmonary embolism, 3 with connective tissue disease, 2 with aortitis syndrome and 6 with other diseases. Scintigrams of mismatch with impaired ventilation and normal perfusion were mainly seen in chronic obstructive lung diseases. Of the 10 patients with bronchial asthma, 5 had scintigrams of improved ventilation after intravenous injection of 250 mg aminophilline, but none of patients with emphysema. The combined scintigraphy has made significant contributions to diagnosis and management of patients with pulmonary disease where the chest X-ray is unhelpful. (author)

    A lady with aortitis syndrome developed in-stent restenosis (ISR) of the innominate artery stent and critical stenosis of right internal carotid artery. The therapeutic challenge was gaining access to the carotid vessel, after treating the innominate artery ISR and all the while using distal protection to circumvent potential cerebral embolism. Percutaneous transluminal angioplasty (PTA) with or without stenting is a safe therapeutic option for re-vascularization of the supra aortic vessels. In the event of re-stenosis, re-treatment with PTA and stenting is safe. Ample evidence-base exists now for carotid artery stenting (CAS) in preference to carotid endarterectomy in patients with stenotic lesions of the carotid vessels. (author)

    Full Text Available The paper describes a clinical case of the typical variant of Cogan's syndrome (CS, a new nosological entity in the current classification of systemic vasculitides (SV, which belongs to a group of variable vasculitides. The literature review highlights in detail the problems of the diagnosis and treatment of this rare disease.CS is characterized by inflammatory eye involvement (interstitial keratitis, uveitis, and episcleritis and hearing problems (sensorineural hearing loss, vestibular disorders with the possible development of vasculitis at other sites, aortitis, and aortic or mitral lesions. A systemic lesion involving the ears and eyes necessitates to rule out granulomatosis with polyangiitis (Wegener's and to make a differential diagnosis with a wide range of diseases. The given data underline the need for the interdisciplinary collaboration of rheumatologists, otorhinolaryngologists, audiologists, oculists, and cardiologists in order to improve the diagnosis and treatment of this form of SV.

    This article deals with not only CT-endoscopy (CTES) technique but also various imaging and processing techniques of 3D CT. CTES images, which were obtained from 137 patients with suspected cardiovascular disorder or disease of other tubular organs, were reconstructed using a newly developed volumetric scanner with a slip-ring system. Among the 137 patients, 107 (78%) were successfully diagnosed by CTES. For cardiovascular region, dissecting aneurysm was detected in 27/32, aortitis in 9/9, and intra-arterial thrombosis in 5/6. Various imaging and processing techniques, including CT number conversion technique, multi-threshold range imaging, 'open-window' and 'virtual operation', and long segmental arteriogram by intravenous contrast injection, are displayed in futures. In conclusion, CTES might become a safe and minimally invasive means for observing the inner surface of the tubular organs, particularly of the aorta, without the need of fiberscopic manipulation.

    The vasculitis can be the consequence of malignancy: most often hematologic rather than solid tumors. The association between large vessels vasculitis and myelodysplastic syndrome is rare. A 55-year-old man experienced asthenia, fever, polyarthritis and inflammatory syndrome. Haematological investigations found a type 2 refractory anemia with excess blasts (RAEB-2) with discovery of severe anemia (Hb: 7,8g/dl) and thrombopenia (platelets: 40,000/mm 3 ). Radiological examinations found thoracic aortitis and carotid vasculitis. Treatment in the form of steroids and azacitidine was instituted. The lack of control of both RAEB-2 and vasculitis was responsible for the death of the patient. Myelodysplastic syndrome and large vessels vasculitis is a rare but serious association disease. The lack of efficiency of corticosteroids seems to be common. Prognosis depends on the haematological treatment effectiveness.

    ECG-gated cine mode magnetic resonance (MR) imaging was performed in 20 patients with various heart deseases. Left ventricular volume (LVV) and left ventricular ejection fraction (LVEF) were calculated on MR images obtained in left ventricular vertical and horizontal long axis views. The findings were compared with those obtained from left ventriculography. There was a significant positive correlation between MR imaging and ventriculography for both LVV and LVEF (p<0.001). In Marfan syndrome after surgery for dissecting aneurysm of the aorta, MR imaging was capable of visualizing not only the whole aorta in a single plane but also enlargement of the aortic root. It also depicted asynergy and thinned wall of the infarcted myocardium for myocardial infarction; an enlarged left auricle, the thickened septum, and constricted outflow tract for idiopathic hypertrophic subaortic stenosis; shunt flow for ventricular septum defect; and an enlarged aortic root for aortitis syndrome. Using ventriculography as the standard, cine MR imaging was frequently false positive for the detection of mitral regurgitation. There was, however, good concordance between MR imaging and ventriculography in detecting aortic regurgitation. In addition, MR imaging was equivalent to color Doppler technique for detecting valvular regurgitation. (N.K.).

    The purpose of this study was to compare the diagnostic value of two-dimensional echocardiography with that of other methods in the detection and localization of aneurysm involving the ascending aorta in patients with annuloaortic ectasia. Two-dimensional echocardiography, RI angiography, CT scan and aortography were performed in 19 patients (12 patients with Marfan's syndrome, 4 with aortitis syndrome and 3 with postoperative perivalvular aneurysm). Eight of 12 patients with Marfan's syndrome had dissection in the ascending aorta which was confirmed at surgery or autopsy. The following observations were obtained. 1) Dissection of the ascending aorta was clearly demonstrated on the two-dimensional echocardiogram in 7 patients by recording the intinal tear and flap, and in these cases the short axis two-dimensional echocardiogram of the ascending aorta was more useful in identifying the site and extent of dissection. 2) In patients with postoperative perivalvular aneurysms, RI angiography proved to be a more useful and sensitive technique in differentiating a leakage into the aneurysm from clots in the aneurysm. 3) CT scanning proved to be an insensitive technique to detect dissection of the ascending aneurysm and to differentiate a leakage from clots in the perivalvular aneurysm. From these observations, we concluded that two-dimensional echocardiography and RI angiography proved to be sensitive techniques in detecting dissection of the ascending aneurysm and evaluating a postoperative aneurysm in patients with annuloaortic ectasia.

    Peripheral arterial disease (PAD) encompasses disease of all arteries of the body except the coronary arteries. The main etiology whatever the patient's age is atherosclerosis. Different etiologies can induce PAD especially when patients are younger than 50 years old and have no cardiovascular risk factors (smoking, hypertension, diabetes…). PAD that appears before 50 years old can be named juvenile PAD (JPAD) although there is no consensus about the definition. The aim of this work is to present the different etiologies of JPAD according to their hereditary, acquired or mixed origins. The following hereditary causes are addressed: Marfan syndrome, Ehlers-Danlos syndrome, homocystinuria, pseudoxanthoma elasticum, osteogenesis imperfecta "mid-aortic" syndrome. Among the acquired etiologies, inflammatory JPADs without extravascular signs such as atherosclerosis and Buerger's disease, inflammatory JPADs with extravascular signs as Takayasu's disease, Behçet's disease and Cogan's syndrome, JPADs like aortitis, embolic JPADs, iatrogenic JPADs, and mechanical or traumatic JPADs are described. Finally, mixed origins as thrombotic disease and fibromuscular dysplasia are presented. This work will assist clinicians in the diagnosis of JPAD. Copyright © 2016 Elsevier Masson SAS.

    To evaluate the clinical usefulness of magnetic resonance imaging (MRI) in the cardiovascular disease, 21 patients were examined using 0.35 and 1.5 Tesla superconductive type (Magnetom, Siemens). In our study, all patients were performed using ECG-gated MRI. Therefore, the cardiac chambers were discriminated clearly from the myocardial wall compared to non-gated MRI. Gated-MRI was performed in 6 normal persons in the operating field at 0.35 and 1.5 Tesla. The image of the latter showed superior than that of the former because of high S/N ratio. In myocardial infarction, infarct area was demonstrated as the wall thinning in 4 of 5 patients. Hypertrophic cardiomyopathy showed thickened left ventricle associated with its narrowed cavity in 7 patients. In the remaining such as congenital and valvular heart disease, global and regional cardiac morphology were assessed noninvasively by gated MRI. In addition, gated MRI was also applied to the diagnosis of peripheral vascular diseases. In dissecting aneurysm, double channels with an intimal flap in the aorta were clearly visualized. And in the aortitis syndrome, aortic dilatation and stenosis were also assessed noninvasively. In conclusion, gated MRI in diagnosing various abnormalities of cardiovascular disease was confirmed.

    Full Text Available Objective: It is controversial whether microorganisms play a role in the pathogenesis of large and medium vessel vasculitides (eg, giant cell arteritis [GCA], Takayasu arteritis [TAK] and focal idiopathic aortitis [FIA]. Recent studies have reported the presence of Varicella Zoster Virus (VZV within formalin-fixed, paraffin-embedded temporal arteries and aortas of about three-quarters or more of patients with these conditions, and in a minority of controls. In a prospective study, we sought to confirm these findings using DNA extracted from vessels that were harvested under surgically aseptic conditions and snap frozen. Methods and Results: DNA samples extracted from 11 surgically sterile temporal arteries and 31 surgically sterile thoracic aortas were used in an attempt to identify the vessel-associated VZV genome. Two different validated PCR methods were used. Thirty-one thoracic aorta aneurysm specimens included biopsies from 8 patients with GCA, 2 from patients with TAK, 6 from patients with FIA, and 15 from patients without vasculitis, who had non-inflammatory aneurysms. Eleven temporal artery biopsies were collected from 5 patients with GCA and 6 controls. The presence of VZV was not identified in either the specimens from patients with large vessel vasculitis or from the controls. Conclusions: Using surgically sterile snap-frozen specimens, we were unable to confirm recent reports of the presence of VZV in either aortas or temporal arteries from patients with large vessel vasculitis or controls.

    We have been using the flanged composite aortic prosthesis and Carrel button technique to re-attach the coronary ostia in aortic root replacement procedures at our institution over the last twenty five years. Our objective was to evaluate the long-term results of aortic root replacement with this technique. A total of 73 patients from January 1984 to August 2010 were included in this study. The median age was 52.7 ± 14.4 years (range 28-80 years). There were 48 male and 25 female patients. 44 patients (60.3%) had annuloaortic ectasia, and 15 patients (20.5%) had acute type A aortic dissection. Marfan syndrome was recognized in 12 patients (16.5%). The early mortality rate was 5.5% (n = 4). Causes of death were multiple organ failures in two patients and sepsis in another two patients. The actuarial survival rate was 84.2% at 5 years, 64.3% at 15 years and 51.9% at 25 years. Only one patient with aortitis needed a reoperation because of coronary pseudoaneurysm after 23 years from the previous operation. This modified Bentall procedure is reliable and safe, with superior long-term survival and a low rate of aortic reoperation.

    Aortitis is a rare cause of aortic dissection. We report the unusual presentation of a 77-year-old male patient who underwent emergency surgery for an aortic dissection type A. A purulent pericardial fluid and inflammatory aorta were found after chest opening. Several samples were sent for analysis. The ascending aorta presented a mild dilatation with a large haematoma infiltrating the aortic root. The distal part of the ascending aorta seemed unaffected. The aortic rupture was found one centimetre above the non-coronary cusp. Aortic wall tissues were extremely fragile and with an inflammatory aspect. The patient died in the theatre room. In the histological study one out of three fragments of ascending aorta displayed longitudinal splitting of the outer media, with blood extravasation in the adventitial layer. In this level, the presence of a detritus material that reminded of bacterial colonies was noteworthy, together with abundant fibrinous exudates. In the laboratory a new specimen, Dietzia maris, was found in the pericardial liquid and in the aortic wall. We believe that this is the first reported finding of Dietzia maris in a patient with aortic disease.

    It is controversial whether microorganisms play a role in the pathogenesis of large and medium vessel vasculitides (eg, giant cell arteritis [GCA], Takayasu arteritis [TAK] and focal idiopathic aortitis [FIA]). Recent studies have reported the presence of Varicella Zoster Virus (VZV) within formalin-fixed, paraffin-embedded temporal arteries and aortas of about three-quarters or more of patients with these conditions, and in a minority of controls. In a prospective study, we sought to confirm these findings using DNA extracted from vessels that were harvested under surgically aseptic conditions and snap frozen. DNA samples extracted from 11 surgically sterile temporal arteries and 31 surgically sterile thoracic aortas were used in an attempt to identify the vessel-associated VZV genome. Two different validated PCR methods were used. Thirty-one thoracic aorta aneurysm specimens included biopsies from 8 patients with GCA, 2 from patients with TAK, 6 from patients with FIA, and 15 from patients without vasculitis, who had non-inflammatory aneurysms. Eleven temporal artery biopsies were collected from 5 patients with GCA and 6 controls. The presence of VZV was not identified in either the specimens from patients with large vessel vasculitis or from the controls. Using surgically sterile snap-frozen specimens, we were unable to confirm recent reports of the presence of VZV in either aortas or temporal arteries from patients with large vessel vasculitis or controls.

    The bone marrow distribution of Ga-67 citrate may be influenced by various elements in serum. In order to make these points clear, 1,955 whole body images were reviewed on the relationship between the accumulation of bone marrow and laboratory examination data of each patients. Increasing accumulation in the bone marrow was determined as positive when the bones of lower extremities were deposited on the images, because these bones was not visualized in normal gallium image. Laboratory data of 20 patients without having bone marrow accumulation was used as control. The positive findings of bone marrow accumulation was observed in 38 patients (2%) including 23 malignancies and 15 benign disease. The malignant tumor infiltration to the bone marrow was demonstrated by bone marrow aspiration biopsy in 2 out of 7 patients with bone marrow accumulation of Ga-67. Seven out of 15 patients with benign disease were collagen disease such as aortitis syndrome or SLE. The values of hemoglobin, hematocrit, serum iron and creatinine clearance were significantly lower in the patients with positive findings in comparison with control. These results suggest that the lower level of serum iron and anemia may cause increasing bone marrow accumulation of Ga-67 citrate. (author).

    Full Text Available It was reported previously that a Candida albicans water-soluble fraction (CAWS, including a mannoprotein and β-glucan complex, has strong potency in inducing fatal necrotizing arteritis in DBA/2 mice. In this study, histopathological changes and cardiac function were investigated in this system. One mg/day of CAWS was given to DBA/2 mice via peritoneal injection for five days. The CAWS-treated DBA/2 mice were induced aortitis and died at an incidence of 100% within several weeks. Histological findings included stenosis in the left ventricular outflow tract (LVOT and severe inflammatory changes of the aortic valve with fibrinoid necrosis. Cardiomegaly was observed and heart weight increased 1.62 fold (<0.01. Echocardiography revealed a severe reduction in contractility and dilatation of the cavity in the left ventricle (LV: LV fractional shortening (LVFS decreased from 71% to 38% (<0.01, and the LV end-diastolic diameter (LVDd increased from 2.21 mm to 3.26 mm (<0.01. The titer of BNP mRNA increased in the CAWS-treated group. Severe inflammatory changes resulting from CAWS brought about lethal LV dysfunction by aortic valve deformation with LVOT stenosis. This system is proposed as an easy and useful experimental model of heart failure because CAWS arteritis can be induced by CAWS injection alone.

    Despite the positive clinical results of valve-sparing aortic root replacement, little is known about the causes of reoperations and the modes of failure. From October 1999 to June 2010, 101 patients underwent valve-sparing aortic root replacement using the David reimplantation technique. The definition of aortic root repair failure included the following: (1) intraoperative conversion to the Bentall procedure; (2) reoperation performed because of aortic regurgitation; and (3) aortic regurgitation equal to or greater than a moderate degree at the follow-up. Sixteen patients were considered to have repair failure. Three patients required intraoperative conversion to valve replacement, 3 required reoperation within 3 months, and another 8 required reoperation during postoperative follow-up. At initial surgery 5 patients had moderate to severe aortic regurgitation, 6 patients had acute aortic dissections, 3 had Marfan syndrome, 2 had status post Ross operations, 3 had bicuspid aortic valves, and 1 had aortitis. Five patients had undergone cusp repair, including Arantius plication in 3 and plication at the commissure in 2. The causes of early failure in 6 patients included cusp perforation (3), cusp prolapse (3), and severe hemolysis (1). The causes of late failure in 10 patients included cusp prolapse (4), commissure dehiscence (3), torn cusp (2), and cusp retraction (1). Patients had valve replacements at a mean of 23 ± 20.9 months after reimplantation and survived. Causes of early failure after valve-sparing root replacement included technical failure, cusp lesions, and steep learning curve. Late failure was caused by aortic root wall degeneration due to gelatin-resorcin-formalin glue, cusp degeneration, or progression of cusp prolapse. Copyright © 2011 The Society of Thoracic Surgeons.

    Objective Kawasaki disease (KD) is the most common cause of acquired cardiac disease in US children. In addition to coronary artery abnormalities and aneurysms, it can be associated with systemic arterial aneurysms. We evaluated the development of systemic arterial dilatation and aneurysms, including abdominal aortic aneurysm (AAA) in the Lactobacillus casei cell wall extract (LCWE)-induced KD vasculitis mouse model. Methods and Results We discovered that in addition to aortitis, coronary arteritis and myocarditis, the LCWE-induced KD mouse model is also associated with abdominal aorta dilatation and AAA, as well as renal and iliac artery aneurysms. AAA induced in KD mice was exclusively infrarenal, both fusiform and saccular, with intimal proliferation, myofibroblastic proliferation, break in the elastin layer, vascular smooth muscle cell loss, and inflammatory cell accumulation in the media and adventitia. Il1r−/−, Il1a−/−, and Il1a−/− mice were protected from KD associated AAA. Infiltrating CD11c+ macrophages produced active caspase-1 and caspase-1 or NLRP3 deficiency inhibited AAA formation. Treatment with IL-1R antagonist (Anakinra), anti-IL-1α, or anti-IL-1β mAb blocked LCWE-induced AAA formation. Conclusions Similar to clinical KD, the LCWE-induced KD vasculitis mouse model can also be accompanied by AAA formation. Both IL-1α and IL-1β play a key role, and that use of an IL-1R blocking agent that inhibits both pathways may be a promising therapeutic target not only for KD coronary arteritis, but also for the other systemic arterial aneurysms including AAA that maybe seen in severe cases of KD. The LCWE-induced vasculitis model may also represent an alternative model for AAA disease. PMID:26941015

    We report the case of a 53 year old man with a chronic periaortitis (CP) in whom Fluorine 18 Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has been useful in assessing the disease extent at diagnosis, in evaluating the treatment response, in diagnosing the relapse, and in monitoring the disease activity during follow up. This case highlights the usefulness of FDG PET/CT at different times in patients with CP. CP is a rare inflammatory disorder that affects the abdominal aorta and the retroperitoneum. Imaging procedures are essential to diagnose and monitor the disease course. Ultrasonography may be used as first line screening test, and is particularly useful to monitor patients with hydronephrosis and aortic aneurysms. However, CT or magnetic resonance imaging (MRI) of the abdomen are currently considered the investigations of choice to diagnose CP. In active CP, the periaortic mass usually enhances on CT and MRI. Both these methods can be used to monitor the disease course of CP and to evaluate response to treatment. A note of caution: signs of vasculitis seen on MRI and CT may persist for some time, despite achievement of clinical remission. A further limitation of abdominal CT and MRI is that neither technique can detect vasculitis in vessels other than the abdominal aorta, which has been described in 43% of patients with CP. FDG PET/CT has been proposed as useful tool in inflammatory diseases, such as aortitis, because metabolic changes assessed by FDG PET/CT usually precede morphological changes assessed by conventional imaging methods. Our case highlights the usefulness of FDG PET/CT at different times in patients with CP. This method may be useful in assessing disease activity and extent at diagnosis, in evaluating the treatment response, in diagnosing the relapse, and in monitoring the disease during follow up.

    Kawasaki disease (KD) is the leading cause of acquired heart disease among children in developed countries. Coronary lesions in KD in humans are characterized by an increased presence of infiltrating CD3+ T cells; however, the specific contributions of the different T cell subpopulations in coronary arteritis development remain unknown. Therefore, we sought to investigate the function of CD4+ and CD8+ T cells, Treg cells, and natural killer (NK) T cells in the pathogenesis of KD. We addressed the function of T cell subsets in KD development by using a well-established murine model of Lactobacillus casei cell wall extract (LCWE)-induced KD vasculitis. We determined which T cell subsets were required for development of KD vasculitis by using several knockout murine strains and depleting monoclonal antibodies. LCWE-injected mice developed coronary lesions characterized by the presence of inflammatory cell infiltrates. Frequently, this chronic inflammation resulted in complete occlusion of the coronary arteries due to luminal myofibroblast proliferation (LMP) as well as the development of coronary arteritis and aortitis. We found that CD8+ T cells, but not CD4+ T cells, NK T cells, or Treg cells, were required for development of KD vasculitis. The LCWE-induced murine model of KD vasculitis mimics many histologic features of the disease in humans, such as the presence of CD8+ T cells and LMP in coronary artery lesions as well as epicardial coronary arteritis. Moreover, CD8+ T cells functionally contribute to the development of KD vasculitis in this murine model. Therapeutic strategies targeting infiltrating CD8+ T cells might be useful in the management of KD in humans. © 2016, American College of Rheumatology.

    Full Text Available Background: The advantages of using a homograft in valve replacement surgery are the excellent hemodynamic profile, low risk of thromboembolism, and low risk of prosthetic valve infection. The aim of this study was to evaluate the long-term outcomes of homograft implantation in the aortic valve position. Methods: This is a retrospective study of 33 patients (>20 years old who underwent aortic valve replacement or root replacement with homografts between April 1995 and May 2015. Valves were collected within 24 hours from explanted hearts of heart transplant recipients (<60 years and organ donors who were not suitable for heart transplantation. The median follow-up duration was 35.6 months (range, 0 to 168 months. Results: Aortic homografts were used in all patients. The 30-day mortality rate was 9.1%. The 1- and 5-year survival rates were 80.0%±7.3% and 60.8%±10.1%, respectively. The 1-, 5-, and 10-year freedom from reoperation rates were 92.3%±5.2%, 68.9%±10.2%, and 50.3%±13.6%, respectively. The 1-, 5-, and 10-year freedom from significant aortic dysfunction rates were 91.7%±8.0%, 41.7%±14.2%, and 25.0%±12.5%, respectively. Conclusion: Homografts had the advantages of a good hemodynamic profile and low risk of thromboembolic events, and with good outcomes in cases of aortitis.

    The vasculitis of Behçet disease (BD) is distinctive because of involvement of both arteries and veins of all sizes. The concept of vasculo-Behçet disease has been adopted for cases in which vascular manifestations are present and often dominate the clinical features. While venous manifestations are frequent and have been reported in many publications, data regarding arterial lesions in patients with BD are rare and often isolated. In this study, we report the main characteristics, treatment, and long-term outcome of 101 patients with arterial lesions among a cohort of 820 (12.3%) BD patients. Factors that affect prognosis were assessed by multivariate analysis. There were 93 (91.2%) male patients; the median (Q1-Q3) age at diagnosis of BD was 33 (27-41) years. Arterial lesions included aneurysms (47.3%), occlusions (36.5%), stenosis (13.5%), and aortitis (2.7%). Lesions mainly involved the aorta (n = 25) and femoral (n = 23) and pulmonary (n = 21) arteries. Patients with arterial lesions were more frequently male (91.2% vs. 62.4%, respectively; p = 0.017) and had higher rates of venous involvement (80.4% vs. 29.8%, respectively; p < 0.001) compared to patients without arterial manifestations. Thirty-nine (38.6%) patients achieved complete remission. In multivariate analysis, the presence of venous involvement (odds ratio [OR], 0.29; 95% confidence interval [CI], 0.08-1.11) and arterial occlusive lesions (OR, 0.13; 95% CI, 0.01-1.25) were negatively associated with complete remission. The use of immunosuppressants (OR, 3.38; 95% CI, 0.87-13.23) was associated with the occurrence of complete remission. The 20-year survival rate was significantly lower in BD patients with arterial involvement than in those without arterial lesions (73% vs. 89%, respectively; p < 0.0001). In conclusion, the long-term outcome of arterial lesions in BD is poor, especially in the case of occlusive lesions and associated venous involvement. The use of immunosuppressants improved the

    The physiological infrarenal aortic diameter varies between 12.4 mm in women an 27.6 mm in men. As defined, an aneurysmatic dilatation begins with 29 mm. According to that, 9% of all people above the age of 65 are affected by an abdominal aortic aneurysm (AAA). Compared with the female sex, the male sex predominates at a rate of about 5:1. The disease is predominant in men of the white race. In black men, black and white women the incidence of AAA is identical. 38 to 50 percent of the AAA patients (patients) suffer from hypertension, 33 to 60% from coronary, 28% from cerebrovascular and 25% from peripheral occlusive disease. The AAA expansion rate varies between 0.2 and 0.8 cm per year and is exponential from a diameter of 5 cm on. In autopsy studies, the rupture rates with AAA diameters of 7 cm were below 5%, 39% and 65%, respecitvely. 70% of the AAA patients do not die of a rupture, but of a cardiac disease. Serum markers, such as metalloproteinases and procollagen peptides are significantly increased in AAA patients. Thoraco-abdominal aneurysms (TAA) make up only 2 to 5% of all degenerative aneurysms. 20 to 30% of the TAA patients are also affected by an AAA. 80% of the TAA are degenerative, 15 to 20% are a consequence of the chronic dissection - including 5% of Marfan patients -, 2% occur in case of infections and 1 to 2% in case of aortitis. The TAA incidence in 100,000 person-years is 5.9% during a monitoring period of 30 years. In case of TAA, an operation is indicated with a maximum diameter of 5.5 to 6 cm and more and, in case of a Marfan's syndrome (incidence of 1:10,000), with a maximum diameter of 5.5 cm and more. With regard to aorto-iliac occlusive diseases, there are defined 3 types of distribution. Type I refers to the region of the bifurcation itself. Type II defines the diffuse aortoiliac spread of the disease. Type III designates multiple-level occlusions also beyond the inguinal ligament. Type I patients in most cases are female and more

    We present our experience of total aortic arch replacement. Twenty-nine patients (21 males and 8 females; mean age 63.3 ± 13.3 years) with extended thoracic aortic aneurysms underwent graft replacement. The pathology of the diseased aorta was non-dissecting aneurysm in 11 patients, including one aortitis and aortic dissection in 18 patients (acute type A: one, chronic type A: 11, chronic type B: six). Five patients had Marfan syndrome. In their previous operation, two patients had undergone the Bentall procedure, three had endovascular stenting, one had aortic root replacement with valve sparing and 12 had hemi-arch replacement for acute type A dissection. Approaches to the aneurysm were as follows: posterolateral thoracotomy with rib-cross incision in 16, posterolateral thoracotomy extended to the retroperitoneal abdominal aorta in seven, mid-sternotomy and left pleurotomy in three, anterolateral thoracotomy with partial lower sternotomy in two and clam-shell incision in one patient. Extension of aortic replacement was performed from the aortic root to the descending aorta in 4, from the ascending aorta to the descending aorta in 17 and from the ascending to the abdominal aorta in eight patients. Arterial inflow for cardiopulmonary bypass consisted of the femoral artery in 15 patients, ascending aorta and femoral artery in seven, descending or abdominal aorta in five and ascending aorta in two. Venous drainage site was the femoral vein in 10, pulmonary artery in eight, right atrium in five, femoral artery with right atrium/pulmonary artery in four and pulmonary artery with right atrium in two patients. The operative mortality, 30-day mortality and hospital mortality was one (cardiac arrest due to aneurysm rupture), one (rupture of infected aneurysm) and one (brain contusion), respectively. Late mortality occurred in three patients due to pneumonia, ruptured residual aneurysm and intracranial bleeding. Actuarial survival at 5 years after the operations was 80.6

    This study investigated the value of fluorine-18 2'-deoxy-2-fluoro-D-glucose (FDG) imaging with a double-headed gamma camera operated in coincidence (hybrid PET) detection mode in patients with suspected spondylitis. Comparison was made with conventional nuclear medicine imaging modalities and magnetic resonance imaging (MRI). Sixteen patients with suspected spondylitis (nine male, seven female, mean age 59 years) prospectively underwent FDG hybrid PET (296 MBq) and MRI. For intra-individual comparison, the patients were also imaged with technetium-99m methylene diphosphonate (MDP) (555 MBq) (n=13) and/or gallium-67 citrate (185 MBq) (n=11). For FDG hybrid PET, two or three transverse scans were performed. Ratios of infected (target) to non-infected (background) (T/B) vertebral bodies were calculated. MR images were obtained of the region of interest. Patients found positive for spondylitis with MRI and/or FDG hybrid PET underwent surgical intervention and histological grading of the individual infected foci. Twelve out of 16 patients were found to be positive for spondylitis. Independent of the grade of infection and the location in the spine, all known infected vertebrae (n=23, 9 thoracic, 12 lumbar, 2 sacral) were detected by FDG hybrid PET. T/B ratios higher than 1.45±0.05 (at 1 h p.i.) were indicative of infectious disease, whereas ratios below this value were found in cases of degenerative change. FDG hybrid PET was superior to MRI in patients who had a history of surgery and suffered from a high-grade infection in combination with paravertebral abscess formation (n=2; further computed tomography was needed) and in those with low-grade spondylitis (n=2, no oedema) or discitis (n=2, mild oedema). False-positive 67 Ga citrate images (n=5: 2 spondylodiscitis, 1 aortitis, 1 pleuritis, 1 pulmonary tuberculosis) and 99m Tc-MDP SPET (n=4: 1 osteoporosis, 2 spondylodiscitis, 1 fracture) were equally well detected by FDG hybrid PET and MRI.

    2007-01-01

    A morphological study of coronary ostia was performed in 70 autopsied human hearts, with particular attention being focused on the funnel-shaped structure, aging changes, and relation to atherosclerosis. The following results were obtained: The ostium is particularly well-defined and forms a funnel-shaped structure. The structure is predominantly a double circular shape on the right and comet-shaped on the left. The funnel-shaped structure of coronary ostia is characterized by a longitudinal smooth muscle arrangement in the inner layer and circular one in the outer layer. Including overhang formation, coronary sclerosis of the ostium appears mainly on the upper margin of the funnel-shaped structure of the right ostium and at the upper right margin of the left. In ischemic heart disease, along with changes in coronary arteries themselves, changes in the ostia of these arteries should be paid close attention. Ostial stenosis of the coronary artery in the absence of distal vessel obstructions, isolated ostial stenosis, is a rare form of coronary artery disease. In a previous review of the international literature, the incidence of coronary ostial stenosis varied between 0.13% and 2.7%. Among 7,500 patients undergoing selective coronary cineangiography at Juntendo University Hospital and Juntendo Urayasu Hospital from 1975 to 1990, five women (0.07%) were diagnosed as having ''isolated coronary ostial stenosis'', of which the cause is unknown. Atherosclerosis, particularly early premature atherome, congenital coronary anomaly, fibro-muscular dysplasia, Takayasu's aortitis, humoral factors, spasm, and iatrogenic events have been considered as its causes. In contrast to usual atherosclerotic coronary artery disease, patients with isolated coronary ostial stenosis of unknown etiology were characterized as being middle-aged, premenopausal, slender females having few coronary risk factors, experiencing severe angina pector is with marked ischemic electrocardiogram changes

    The physiological infrarenal aortic diameter varies between 12.4 mm in women an 27.6 mm in men. As defined, an aneurysmatic dilatation begins with 29 mm. According to that, 9% of all people above the age of 65 are affected by an abdominal aortic aneurysm (AAA). Compared with the female sex, the male sex predominates at a rate of about 5:1. The disease is predominant in men of the white race. In black men, black and white women the incidence of AAA is identical. 38 to 50 percent of the AAA patients (patients) suffer from hypertension, 33 to 60% from coronary, 28% from cerebrovascular and 25% from peripheral occlusive disease. The AAA expansion rate varies between 0.2 and 0.8 cm per year and is exponential from a diameter of 5 cm on. In autopsy studies, the rupture rates with AAA diameters of <5 cm, between 5.1 and 6.9 cm, and of >7 cm were below 5%, 39% and 65%, respecitvely. 70% of the AAA patients do not die of a rupture, but of a cardiac disease. Serum markers, such as metalloproteinases and procollagen peptides are significantly increased in AAA patients. Thoraco-abdominal aneurysms (TAA) make up only 2 to 5% of all degenerative aneurysms. 20 to 30% of the TAA patients are also affected by an AAA. 80% of the TAA are degenerative, 15 to 20% are a consequence of the chronic dissection - including 5% of Marfan patients -, 2% occur in case of infections and 1 to 2% in case of aortitis. The TAA incidence in 100,000 person-years is 5.9% during a monitoring period of 30 years. In case of TAA, an operation is indicated with a maximum diameter of 5.5 to 6 cm and more and, in case of a Marfan's syndrome (incidence of 1:10,000), with a maximum diameter of 5.5 cm and more. With regard to aorto-iliac occlusive diseases, there are defined 3 types of distribution. Type I refers to the region of the bifurcation itself. Type II defines the diffuse aortoiliac spread of the disease. Type III designates multiple-level occlusions also beyond the inguinal ligament. Type I

    Full Text Available Foram estudados 27 pacientes submetidos a implante de tubo de Dacron valvulado (segundo técnica de Bentall-De Bono, entre 1976 e 1985. Todos apresentavam ectasia ânulo-aórtica, que era devida a necrose cística da média em 23 pacientes (85,2%, dissecção crônica de aorta em 3 pacientes (11,1% e aortite luética em 1 paciente (3,7%. A faixa etária foi de 29 a 64 anos (m = 48 anos. Três eram do sexo feminino e 24, do masculino. Foi utilizado tubo de Dacron 28 ou 30 mm em todos. As válvulas utilizadas foram: de dura-máter em 7 pacientes, de aorta heteróloga em 9 e metálica em 11 pacientes. A classe funcional era I-II em 7 pacientes e III-IV em 19 pacientes (NYHA. Houve 1 óbito (3,7% pós-operatório imediato, por sangramento incontrolável e insuficiência renal aguda. As complicações mais freqüentes foram arritmias (13 pacientes, 48% e hemorragia (3 pacientes, 11 %. No pós-operatório tardio faleceram 9 pacientes, pelas seguintes causas: morte súbita (2 pacientes, 7,4%, insuficiência cardíaca aguda (2 pacientes, 7,4%, hemorragia após reoperação (1 paciente, 3,7%, infecção hospitalar (1 paciente, 3,7%, endocardite infecciosa (1 paciente, 3,7% e causa acidental (7,4%. Cinco pacientes (18,5% foram reoperados no pós-operatório tardio, 2 por disfunção de prótese, 2 por endocardite infecciosa sobre tubo de Dacron e 1 por fístula perivalvular. A curva atuarial mostrou uma probabilidade de sobrevida de 83,7% até o 3? ano, 61 % aos 5 anos e 42,7% do 6º ao 9º ano. No fim do período, os 17 pacientes sobreviventes encontram-se em classe funcional I-II (p This is a report of 27 patients presenting annulo-aortic ectasia submitted to surgical correction with a composite valve-tube graft (Bentall-De Bono technique, between 1976 and 1985.
