Sample records for artery steal syndrome

  1. Partial subclavian steal syndrome in a congenitally anomalous subclavian artery

    International Nuclear Information System (INIS)

    Background. A subclavian steal syndrome results from the abnormal flow of blood due to the occlusion in the subclavian artery proximal to the origin of the vertebral artery. A case of a male patient with a partial subclavian steal syndrome is presented. Case report. The syndrome was caused by a stenotic lesion of an aberrant right subclavian artery (the so called lusorian artery). The partial subclavian steal was recognized using the duplex ultrasound which showed the to and fro pattern in the right vertebral artery. Angiography of the aortic arch revealed the arterial anomaly. In our case, duplex ultrasound was a crucial method in diagnosing the partial subclavian steal syndrome. However, in order to show the arterial anomaly, the final evaluation had to be performed using arteriography. Conclusions. The early recognized partial subclavian steal syndrome provides good understanding of patient's symptoms, successful follow up, and a variety of treatment options. (author)

  2. Interventional therapy of complications after liver transplantation: arterial steal syndrome

    International Nuclear Information System (INIS)

    Arterial steal syndrome (ASS), a scarce complication after liver transplantation, is characterized by hepatic arterial hypoperfusion of the graft caused by a shifting of blood flow into the splenic, left gastric, or gastroduodenal arteries. It can lead to stricture formation of biliary system and transplanted liver function exhaustion. The early diagnosis and treatment are important for protecting the transplanted liver function. Dynamic CDFI after liver transplantation as a routine is necessary to find out the suspected lesions, and transcatheter angiography as the gold standardization can give clear dignosis. Embolization of splenic artery is minimally invasive, successful and less complication treatment for ASS and especially the coil embolization of middle segment of splenic artery is the best choice.

    The subclavian-vertebral artery steal syndrome (SSS) is the hemodynamic phenomenon of blood flow reversal in the vertebral artery due to significant stenosis or occlusion of the proximal subclavian artery or the innominate artery. Occasionally, SSS is diagnosed in patients not harboring arterial stenosis. With the exception of arterial congenital malformations, the limited case reports of SSS with intact subclavian artery are attributed to dialysis arteriovenous fistulas (AVFs). Interestingly, these cases are more frequently symptomatic than those with the classical atherosclerotic SSS forms. On the other hand, the disclosure of SSS due to subclavian/innominate artery atherosclerotic stenosis, even in the absence of accompanying symptoms, should prompt a thorough cardiovascular work-up for the early detection of coexisting coronary, carotid, or peripheral artery disease. Herein, we review the incidence, clinical presentation, sonographic findings, and therapeutic interventions related to SSS with and without subclavian/innominate artery stenosis. We also review the currently available data in the literature regarding the association of SSS and dialysis AVF. In addition, we present a patient with bilateral symptomatic SSS as the result of an arteriovenous graft (AVG) that was introduced after the preexisting AVF in the contralateral arm became nonfunctional. SSS due to subclavian or innominate artery stenosis/occlusion is rarely symptomatic warranting interventional treatment. In contrast, when it is attributed to AVF, surgical correction is frequently necessary. PMID:27301069

  4. Transcatheter Splenic Artery Occlusion for Treatment of Splenic Artery Steal Syndrome After Orthotopic Liver Transplantation

    International Nuclear Information System (INIS)

    Purpose: To review some aspects of the problem of splenic artery steal syndrome as cause of ischemia in transplanted livers and treatment by selective splenic artery occlusion. Materials and Methods: Eleven liver transplant patients from a group of 350 patients, nine men and two women,ranging in age from 40 years to 61 years (mean 52 years), presented with biochemical evidences of liver ischemia and failure, ranging from one to 60 days following orthotopic liver transplantation. Diagnosis of splenic artery steal syndrome was suspected by elevated enzymes, Doppler ultrasound and confirmed by celiac angiogram. Patients with confirmed hepatic artery thrombosis before angiography were excluded from the study. Embolization with Gianturco coils was performed. Results: All patients were treated by splenic artery embolization with Gianturco coils. The 11 patients improved clinically within 24 hours of the procedure with significant change in the biochemical and clinical parameters. Followup ranged from one month to two years. One of the 11 patient initially improved, but developed hepatic artery thrombosis within 24 hours of the embolic treatment,requiring surgical repair. Conclusion: Splenicartery steal syndrome following liver transplantation surgery can be diagnosed by celiac angiography, and effectively treated by splenic artery embolization with coils. Embolization is one of the treatments available, it is minimally invasive, and leads to immediate clinical improvement. Hepatic artery thrombosis is a possible complication of the procedure

  5. Arterial steal syndrom in patients after liver transplantation: transarterial embolization of the splenic and gastroduodenal arteries

    International Nuclear Information System (INIS)

    Purpose: To evaluate transaterial embolization of splenohepatic and gastroduodenal steal syndrome in patients with impaired liver function tests after liver transplantation. Methods and Material: In a prospective study 22 patients (10 male, 12 female; mean age 49.5 years) with unexplained elevation of hepatic enzymes after liver transplantation underwent transcatheter arterial embolization of splenohepatic (n = 18) and gastroduodenal (n = 4) steal syndrome with use of Gianturco coils or microcoils. Liver and spleen parenchyma were surveyed and evaluated before and after embolization with plain helical CT, including volumetry of liver and spleen. Results: DSA examinations revealed a dilated splenic artery (n = 18) or gastroduodenal artery (n = 4) combined with a slightly decreased perfusion of the hepatic arteries, while immediately after successful embolization a normal perfusion of the hepatic arteries could be noted. Volumetric measurements before and after embolization showed no significant changes in liver parenchyma (x = + 7% ± 2), and variable changes in splenic volume of - 5% to + 28% (mean, + 11%), with initial measurements. Clinical follow-up examinations revealed a normalization of the previously elevated hepatic enzymes and a normalization of liver function tests after successful embolization. Complications were observed in 4 patients (infarction of the spleen). Conclusions: The preliminary results reveal that in liver transplant candidates with splenohepatic and gastroduodenal steal syndrome successful embolization results in an improvement of organ perfusion with normalization of function tests.

    Full Text Available Patients with multivessel coronary artery disease are more likely to have extensive atherosclerosis that involves other major arteries. Critical subclavian artery (SCA stenosis can result in coronary subclavian steal syndrome that may present as recurrent ischemia and even myocardial infarction in patients with coronary artery bypass graft (CABG. In patients with concomitant severe native coronary disease, occluded saphenous venous grafts (SVG to other arteries, percutaneous intervention on critical subclavian artery (SCA stenosis that will compromise the blood flow to left internal mammary graft (LIMA and left anterior descending (LAD artery will be a high-risk procedure and may be associated with cardiogenic shock, especially in patients with preexisting ischemic cardiomyopathy. The use of percutaneous left ventricular (LV assist device like Impella will offer better hemodynamic support and coronary perfusion and therefore results in decreased myocardial damage, maximized residual cardiac function, and lower incidence of cardiogenic shock.

    Objective. To evaluate the efficacy of subclavian stenosis percutaneous transfemoral angioplasty (PTA)-treatment in patients with intermittent or complete subclavian steal syndrome (SSS), and coronary-subclavian steal syndrome (C-SSS) after left internal mammary artery-interventricular anterior artery (LIMA-IVA) by pass graft. Methods. We studied 42 patients with coronary subclavian steal syndrome subdivided in two groups; the first group consisted of 15 patients who presented an intermittent vertebral-subclavian steal, while the second group consisted of 27 patients with a complete vertebral-subclavian steal. All patients were treated with angioplasty and stent application and were followed up for a period of 5 years by echocolordoppler examination to evaluate any subclavian restenosis. Results. Subclavian restenosis was significantly increased in patients with a complete subclavian steal syndrome. The restenosis rate was 6.67% in the first group and 40.75% in the second group, These patients had 9.1 fold-increase risk (CI confidence interval 0.95-86.48) in restenosis. Conclusion. Patients with a complete subclavian and coronary steal syndrome present a higher risk of subclavian restenosis

    We report a case of erectile dysfunction caused by external iliac artery occlusion, associated with pelvic steal syndrome; bilateral internal iliac arteries were patent. The patient stated that he had experienced erectile dysfunction at similar times along with claudication, but he did not mention it before angiography. He expressed that the erectile dysfunction did not last long and that he felt completely okay after the interventional procedure, in addition to his claudication. Successful treatment of the occlusion, by percutaneous transluminal angioplasty and stent implantation, helped resolve erectile dysfunction completely and treat the steal syndrome.

    The occurrence of an anastomosis between the coronary artery to the systemic artery is rare. However, the probability of hemodynamic changes sufficient to cause clinical symptoms is extremely low. Anastomosis of the coronary to bronchial artery can cause myocardial ischemia due to the decreased flow to the coronary arteries. The authors report a case of coronary to bronchial artery anastomosis presenting as coronary steal syndrome that was treated with transarterial microcoil embolization instead of surgical ligation.

    Branch occlusion of the anterior cerebral artery (ACA) is regarded as a part of Moyamoya disease. The purpose of this study is to define the ACA steal phenomenon (SP) in Moyamoya disease and to evaluate temporal changes according to the disease progression. From 139 Moyamoya patients we defined ACASP as narrowing of the ipsilateral A1-2 junction while preserving the anterior communicating artery and supplying the contralateral ACA cortical branches with the development of leptomeningeal collaterals by the ipsilateral middle cerebral artery into the hypoperfused ipsilateral ACA territory. Direction of the steal related to the stage in both hemispheres by Suzuki classification was statistically analyzed using the binomial test based on binomial distribution. Follow-ups of ACASP were evaluated in five patients. We identified ACASP in 13 (9%) patients (male:female=7:6, mean age 18 years, range: 2-58 years) of the 139 study patients. The presenting pattern was ischemic in 12 and hemorrhagic in one. The direction of SP occurred from the hemisphere in the lower to the higher stage of Suzuki classification (two-tail P value=0.0002). After revascularization surgery, ACASP disappeared or diminished. ACASP may occur in bilaterally different stages of Moyamoya disease as a transient self-adaptive process. It regresses after revascularization surgery. (orig.)

    Non-occlusion of the internal mammary artery side branches may cause ischemia due to flow diversion after coronary artery bypass grafting. The authors present the case of a 67-year-old man with recurrent angina after undergoing myocardial revascularization with a left internal mammary artery to left anterior descending bypass. He presented with impaired anterior wall myocardial perfusion in the setting of a patent left internal mammary artery side branch. Effective percutaneous treatment was carried out through coil embolization, with improved flow and clinical symptoms, confirmed through ischemia testing. Coronary steal through a patent mammary artery side branch is a controversial phenomenon and this type of intervention should be considered only in carefully selected patients. PMID:23809629

Uma das complicações da fístula arteriovenosa é a síndrome do roubo, mas esta é de ocorrência incomum, e o seu tratamento está diretamente indicado quando há sintomas manifestos. Vários métodos foram propostos para sua correção nos membros superiores, sendo considerada a revascularização distal com ligadura arterial o procedimento de escolha. Neste relato de caso inédito, descreve-se o tratamento da síndrome do roubo de uma fístula arteriovenosa realizada em membro inferior, tratada com sucesso por meio da mesma técnica indicada para os membros superiores.Arteriovenous fistula with adequate blood flow is extremely important for patients with chronic renal insufficiency undergoing hemodialysis. Steal syndrome is a complication of arteriovenous fistula, but it is rare and its treatment is directly indicated when there are associated symptoms. Although many treatments have been proposed for its repair in the upper limbs, distal revascularization and interval ligation is currently the treatment of choice. This original case report describes the treatment of steal syndrome secondary to arteriovenous fistula in the lower limb, which was successfully treated using the same procedure described for the upper limbs.

    Various benign and malignant conditions could cause biliary obstruction. Compression of extrahepatic bile duct (EBD) by right hepatic artery was reported as a right hepatic artery syndrome but all cases were compressed EBD from stomach side. Our case compressed from dorsum was not yet reported, so it was thought to be a very rare case. We present here the first case of bile duct obstruction due to the compression of EBD from dorsum by right hepatic artery.

  12. Superior Mesenteric Artery Syndrome or Wilkie Syndrome

    International Nuclear Information System (INIS)

    We described three cases of superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, chronic duodenal ileus, or cast syndrome. This syndrome occurs when the third portion of the duodenum is compressed between the SMA and the aorta. The major risk factors for development of SMA syndrome are rapid weight loss and surgical correction of spinal deformities. The clinical presentation of SMA syndrome is variable and nonspecific, including nausea, vomiting, abdominal pain, and weight loss. The diagnosis is based on endoscopic, radiographic and tomographic findings of duodenal compression by the SMA. The treatment of SMA syndrome is aimed at the precipitating factor, which usually is related to weight loss. Therefore, conservative therapy with nutritional supplementation is the initial approach, and surgery is reserved for those who do not respond to nutritional therapy.

  13. Vascular Steal Explains Early Paradoxical Blood Oxygen Level-Dependent Cerebrovascular Response in Brain Regions with Delayed Arterial Transit Times

    2013-04-01

    Full Text Available Introduction: Blood oxygen level-dependent (BOLD magnetic resonance imaging (MRI during manipulation of inhaled carbon dioxide (CO2 can be used to measure cerebrovascular reactivity (CVR and map regions of exhausted cerebrovascular reserve. These regions exhibit a reduced or negative BOLD response to inhaled CO2. In this study, we sought to clarify the mechanism behind the negative BOLD response by investigating its time delay (TD. Dynamic susceptibility contrast (DSC MRI with the injection of a contrast agent was used as the gold standard in order to provide measurement of the blood arrival time to which CVR TD could be compared. We hypothesize that if negative BOLD responses are the result of a steal phenomenon, they should be synchronized with positive BOLD responses from healthy brain tissue, even though the blood arrival time would be delayed. Methods: On a 3-tesla MRI system, BOLD CVR and DSC images were collected in a group of 19 patients with steno-occlusive cerebrovascular disease. For each patient, we generated a CVR magnitude map by regressing the BOLD signal with the end-tidal partial pressure of CO2 (PETCO2, and a CVR TD map by extracting the time of maximum cross-correlation between the BOLD signal and PETCO2. In addition, a blood arrival time map was generated by fitting the DSC signal with a gamma variate function. ROI masks corresponding to varying degrees of reactivity were constructed. Within these masks, the mean CVR magnitude, CVR TD and DSC blood arrival time were extracted and averaged over the 19 patients. CVR magnitude and CVR TD were then plotted against DSC blood arrival time. Results: The results show that CVR magnitude is highly correlated to DSC blood arrival time. As expected, the most compromised tissues with the longest blood arrival time have the lowest (most negative CVR magnitude. However, CVR TD shows a noncontinuous relationship with DSC blood arrival time. CVR TD is well correlated to DSC blood arrival time

  14. Left carotid steal. A new observation.

    Shumacker, H B; Isch, J H

    1975-04-01

    A patient had an occlusion of the left subclavian artery just proximal to the takeoff of a previously placed subclavian-carotid graft. This caused reversal of flow in the graft and a symptomatic steal of blood via to the intracranial arteries. An axilloaxillary graft restored forward flow. In a second patient, a steal occurred from the right carotid and vertebral systems into the distal carotid system of the left side that has been isolated by a proximal carotide artery occlusion from arteriosclerosis. A saphenous vein, used as a bypass from the subclavian to the carotid artery, restored normal flow. Thus, the carotide system may be the low-pressure area responsible for the steal, although this is rarer than the subclavian. PMID:1147756

    International Nuclear Information System (INIS)

    In patients with Tetralogy of Fallot, collateral supply to the pulmonary artery from systemic arterial sources is frequently encountered. However, collateral blood flow arising from the cerebral circulation has, to our knowledge, not been reported in this condition. We describe a patient with Tetralogy of Fallot in whom the left pulmonary artery filled directly via retrograde flow from the left carotid artery. Review of the literature in search of a similar case was unrevealing. A theoretical embryologic basis for this anomaly is discussed. (orig.)

    Full Text Available Goldenhar Syndrome is characterized by craniofacial, ocular and vertebral defects secondary to abnormal development of the 1st and 2nd branchial arches and vertebrae. Other findings include cardiac and vascular abnormalities. Though these associations are known, the specific anomalies are not well defined. We present a 7-month-old infant with intermittent respiratory distress that did not improve with respiratory interventions. Echocardiogram suggested a double aortic arch. Cardiac CT angiogram confirmed a right arch and aberrant, stenotic left subclavian artery, dilation of the main pulmonary artery, and agenesis of the left thyroid lobe. Repeat echocardiograms were concerning for severely dilated coronary arteries. Given dilation, a rheumatologic workup ensued, only identifying few weakly positive autoantibodies. Further imaging demonstrated narrowing of the aorta below the renal arteries and extending into the common iliac arteries and proximal femoral arteries. Given a physical exam devoid of rheumatologic findings, only weakly positive autoantibodies, normal inflammatory markers, and presence of the coronary artery dilation, the peripheral artery narrowings were not thought to be vasculitic. This case illustrates the need to identify definitive anomalies related to Goldenhar Syndrome. Although this infant’s presentation is rare, recognition of specific vascular findings will help differentiate Goldenhar Syndrome from other disease processes.

    Introduction Severe nephrotic syndrome is associated with increased morbidity and mortality. Renal artery embolization (RAE) has been used in a number of renal diseases such as renal tumors, arteriovenous fistulas etc. However, data regarding benefits of RAE in patients with symptomatic severe proteinuria is limited. We decided to evaluate role of RAE in the setting of severe symptomatic nephrotic syndrome. Methods Eight patients who had undergone transcatheter renal artery embolization with polyvinyl alcohol (PVA) were included. Clinico-demographic characteristics as well as baseline laboratory data including level of proteinuria, serum albumin, C-reactive protein and LDL cholesterol levels were recorded for each patient. After RAE, outpatient clinic control laboratory values were also assessed. Findings All patients except one underwent bilateral RAE (four simultaneous or three sequential). Two patients experienced postembolization syndrome characterized by flank pain, fever, and leukocytosis, which was self-limited and responded to analgesics in all patients. There was no technical complications associated with RAE procedure. All patients became anuric except one. Serum albumin levels increased and serum LDL-cholesterol levels decreased considerably in treated patients. Discussion Renal artery embolization with the purpose of amelioration in nephrotic syndrome complications was effective and free of major technical complications in our patients. PMID:26833695

    Although conventional intraarterial digital subtraction angiography remains the gold standard method for imaging the vertebral artery, noninvasive modalities such as ultrasound, multislice computed tomographic angiography and magnetic resonance angiography are constantly improving and are playing an increasingly important role in diagnosing vertebral artery pathology in clinical practice. This paper reviews the current state of vertebral artery imaging from an evidence-based perspective. Normal anatomy, normal variants and a number of pathological entities such as vertebral atherosclerosis, arterial dissection, arteriovenous fistula, subclavian steal syndrome and vertebrobasilar dolichoectasia are discussed.

We presented the case of a 52-year-old man with no light perception in his right eye. The visual loss was monocular and painless, fundoscopy showed central retinal artery occlusion and the laboratory investigation showed the raised erythrocyte sedimentation rate of 105 mm/h and the raised C-reactive protein of 22 mg/l. Specific laboratory investigations and fluorescein angiography excluded the presence of vasculitis, collagen vascular diseases, hypercoagulable state and antiphospholipid syndrome. Conclusion. The patient met all the five of the National Cholesterol Education Program (NCEP criteria for the metabolic syndrome: hypertension, abnormal lipid profile, abnormal glucose metabolism, obesity and hyperuricemia. Measurement of C-reactive protein is useful for the assessment of therapeutic systemic effect on any abnormality in the metabolic syndrome. Individual therapy for all risk factors in the metabolic syndrome is necessary to prevent complications such as cardiovascular, retinal vascular diseases and stroke.

    2015-01-01

    Superior mesenteric artery (SMA) syndrome (known as Wilkie's syndrome) is a rare cause of upper gastrointestinal obstruction. It is an acquired disorder in which acute angulation of the SMA causes compression of the third part of the duodenum between the SMA and the aorta. This is commonly due to loss of fatty tissue as a result of a variety of debilitating conditions. We report a 17-year-old female who presented with intermittent abdominal pain and intractable vomiting following significant weight loss after hospitalization for pneumonia. Symptoms persisted for 2 years and the patient underwent extensive invasive and non-invasive tests, but to no avail. Thereafter she developed acute high intestinal obstruction, which unraveled her diagnosis. This case emphasizes the challenges in the diagnosis of SMA syndrome and the need for increased awareness of this entity. This will improve early recognition in order to reduce irrelevant tests and unnecessary treatments. PMID:26120301

    International Nuclear Information System (INIS)

    Stealing the Gold presents a survey of some of the most exciting topics in condensed matter physics today, from the perspective of the pioneering work of Sam Edwards. Original articles from leaders in the field, including several Nobel laureates, highlight the historical development as well as new and emerging areas. This book would be of interest to graduate students and researchers in condensed matter physics, statistical physics and theoretical physics. Over the course of nearly half a century, Sam Edwards has led the field of condensed matter physics in new directions, ranging from the electronic and statistical properties of disordered materials to the mechanical properties of granular materials. Along the way he has provided seminal contributions to fluid mechanics, polymer science, surface science and statistical mechanics. This volume celebrates the immense scope of his influence by presenting a collection of original articles by recognized leaders in theoretical physics, including two Nobel laureates and a Fields medalist, which describe the genesis, evolution and future prospects of the various sub-fields of condensed matter theory, along with reprints of a selection of Edwards' seminal papers that helped give birth to the subject. Stealing the Gold, Edwards' favourite caricature of the relationship between theoretical physicists and nature, will be of singular interest to graduate students looking for an overview of some of the most exciting areas of theoretical physics, as well as to researchers in condensed matter physics looking for a comprehensive, broad and uniquely incisive snapshot of their subject at the dawn of the 21st century.

    Full Text Available OBJECTIVES: We investigated the relationship between metabolic syndrome and breast arterial calcification detected via mammography in a cohort of postmenopausal subjects. METHODS: Among 837 patients referred to our radiology department for mammographic screening, 310 postmenopausal females (105 patients with and 205 patients without breast arterial calcification aged 40 to 73 (mean 55.9±8.4 years were included in this study. The groups were compared with respect to clinical characteristics and metabolic syndrome criteria. Univariate and multivariate analyses identified the factors related to breast arterial calcification. RESULTS: Age, postmenopausal duration and the frequencies of diabetes mellitus, hypertension and metabolic syndrome were significantly higher in the subjects with breast arterial calcification than in those without (p<0.05. Multivariate analysis indicated that age (OR = 1.3, 95% CI = 1.1-1.6, p = 0.001 and metabolic syndrome (OR = 4.0, 95% CI = 1.5−10.4, p = 0.005 were independent predictors of breast arterial calcification detected via mammography. The independent predictors among the features of metabolic syndrome were low levels of high-density lipoproteins (OR = 8.1, 95% CI = 1.0−64.0, p = 0.047 and high blood pressure (OR = 8.7, 95% CI = 1.5−49.7, p = 0.014. CONCLUSIONS: The likelihood of mammographic detection of breast arterial calcification increases with age and in the presence of hypertension or metabolic syndrome. For patients undergoing screening mammography who present with breast arterial calcification, the possibility of metabolic syndrome should be considered. These patients should be informed of their cardiovascular risk factors and counseled on appropriate lifestyle changes.

    Ocular ischemic syndrome is a chronic ischemic eye disease including a series of ischemic ocular and brain syndromes caused by carotid artery occlusion or stenosis.Because of the different degrees of ischemia,clinical manifestations of ocular ischemic syndrome are diverse,and it is difficult to diagnose in the initial stage.The main strategy to treat ocular ischemic syndrome is elimination of carotid stenosis.We presented a patient who recovered dramatically after carotid artery stenting.The pre-stenting arm-retinal circulation time of the patient's left eye was prolonged,and a large amount of microaneurysm appeared at the posterior polar and mid-peripheral aspects of the left retina.The post-stenting arm-retinal circulation time of the left eye decreased to 16.3 seconds,and the microaneurysm almost disappeared.

  4. Severe Hypertension Secondary to Renal Artery Stenosis and Cushing's Syndrome

    International Nuclear Information System (INIS)

    We present an unusual patient who simultaneously had severe renal artery stenosis RAS and Cushings syndrome. The case highlights the difficulty of reaching a specific diagnosis of Cushings syndrome and the possible interaction between Cushings syndrome and some other concurrent illnesses that this patient had. A 37-year old man presented with severe hypertension HTN and uncontrolled diabetes mellitus DM without clear physical signs of Cushings syndrome. He was found to have severe osteoporosis, proximal myopathy, several cutaneous warts, tinea versicolor, and chronic viral hepatitis. Captopril-stimulated renal scan and renal artery angiogram revealed severe RAS. Partial balloon dilatation of RAS led to improvement in HTN. Unexpectedly, urine free cortisol 24 hour was found extremely high. Serum adrenocorticotropic hormone ACTH was also elevated and high dose dexamethasone suppression tests were inconclusive. Several imaging studies failed to localize the source of ACTH. Despite normal MRI of the pituitary gland, bilateral inferior petrosal sinus sampling IPSS localized the source of ACTH secretion to the right side of the pituitary gland and right anterior hemihypophysectomy resulted in cure of Cushings disease, HTN, DM, and tinea versicolor with significant improvement in cutaneous warts, osteoporosis, and chronic hepatitis. In conclusion, RAS and Cushings syndrome may occur together. Significant hypercortisolemia can occur without clear signs of Cushings syndrome. Controlling hypercortisolemia is of paramount importance when treating chronic infections in patients with Cushing's syndrome. (author)

    Full Text Available Abstract Introduction This is the first case report of Mirizzi syndrome associated with hepatic artery pseudoaneurysm. Case presentation A 54-year-old man presented with painful obstructive jaundice and weight loss. Computed tomography showed a hilar mass in the liver. Following an episode of haemobilia, angiography demonstrated a pseudoaneurysm of a branch of the right hepatic artery that was embolised. At surgery, a gallstone causing Mirizzi type II syndrome was found to be responsible for the biliary obstruction and a necrotic inflammatory mass and haematoma were found to be extending into the liver. The mass was debrided and drained, the obstructing stones removed and the bile duct drained with a t-tube. The patient made a full recovery. Conclusion This case highlights another situation where there may be difficulty in differentiating Mirizzi syndrome from biliary tract cancer.

    The superior mesenteric artery syndrome (SMAS) is an uncommon condition in children. We describe a case of a 7-year-old boy with SMAS that occurred 3 years after a Deloyers' procedure for subtotal colonic Hirschsprung who was admitted for bilious vomit, abdominal pain and diarrhea due to unrecognized celiac disease. This case emphasize that SMAS in children needs a close medical and surgical follow-up to avoid an underestimation of early clinical signs unrelated to surgery. PMID:25972411

    Three patients developed signs of a unilateral cervical cord lesion 6 to 36 h after the acute onset of severe cervico-brachial pain. The neurological deficit progressed over 6 to 18 h. On the painful side a central Horner's syndrome, a hemiparesis with plegia of the hand, and a slight pallhypaesthesia were found. On the opposite side thermhypaesthesia and hypalgesia were noted with a level at the dermatome C5 or C6. T2-weighted MR images revealed in one patient a small area of increased signal intensity restricted to one half of the cervical cord, and electromyography in another patient showed after 6 months evidence of segmental chronic denervation. Both abnormalities were found at the clinically expected level. The findings are consistent with a small infarction of the cervical cord in the perfusion territory of a central (sulco-commissural) artery, a duplicated anterior spinal artery or an anterior spinal branch of the vertebral artery.

    2013-01-01

    Pulmonary arterial hypertension (PAH) syndrome in broilers (also known as ascites syndrome and pulmonary hypertension syndrome) can be attributed to imbalances between cardiac output and the anatomical capacity of the pulmonary vasculature to accommodate ever-increasing rates of blood flow, as well as to an inappropriately elevated tone (degree of constriction) maintained by the pulmonary arterioles. Comparisons of PAH-susceptible and PAH-resistant broilers do not consistently reveal differences in cardiac output, but PAH-susceptible broilers consistently have higher pulmonary arterial pressures and pulmonary vascular resistances compared with PAH-resistant broilers. Efforts clarify the causes of excessive pulmonary vascular resistance have focused on evaluating the roles of chemical mediators of vasoconstriction and vasodilation, as well as on pathological (structural) changes occurring within the pulmonary arterioles (e.g., vascular remodeling and pathology) during the pathogenesis of PAH. The objectives of this review are to (1) summarize the pathophysiological progression initiated by the onset of pulmonary hypertension and culminating in terminal ascites; (2) review recent information regarding the factors contributing to excessively elevated resistance to blood flow through the lungs; (3) assess the role of the immune system during the pathogenesis of PAH; and (4) present new insights into the genetic basis of PAH. The cumulative evidence attributes the elevated pulmonary vascular resistance in PAH-susceptible broilers to an anatomically inadequate pulmonary vascular capacity, to excessive vascular tone reflecting the dominance of pulmonary vasoconstrictors over vasodilators, and to vascular pathology elicited by excessive hemodynamic stress. Emerging evidence also demonstrates that the pathogenesis of PAH includes characteristics of an inflammatory/autoimmune disease involving multifactorial genetic, environmental, and immune system components.

    Full Text Available Abstract Background Arterial tortuosity syndrome (ATS (OMIM #208050 is a rare autosomal recessive connective tissue disorder characterized by tortuosity and elongation of the large and medium-sized arteries, propensity to aneurysms formation, vascular dissection, and pulmonary arteries stenosis. ATS is caused by mutations in SLC2A10 gene, encoding for the facilitative glucose transporter 10 (GLUT10. So far, 17 SLC2A10 mutations have been reported in 32 families, two of which were Italian with a total of five patients. Here we present the clinical and molecular characterization of two novel Italian paediatric ATS patients. Methods The exons and intronic flanking regions of SLC2A10 gene were amplified and direct sequencing was performed. Results In both patients, the involvement of major- and medium-sized arteries was characteristic; the nonvascular connective tissue manifestations were mild and not pathognomic of the disorder. Both patients, born from non-consanguineous parents, were heterozygous for two different SLC2A10 mutations, three of which were recurrent and one was novel (p.Arg231Trp. This mutation is localized at the endofacial loop between the transmembrane domains 6 and 7 of GLUT10. Conclusion Two novel ATS patients were characterized at clinical and molecular level. Overall, four ATS unrelated families are known in Italy so far. Though ATS clinical delineation improved in the last years, further works in the comprehension of disease presentation and complications onset, particularly in paediatric age, and on ATS molecular basis are needed to add new insights for diagnosis and prevention strategies for related complications.

  15. High prevalence of vertebral artery tortuosity of Loeys-Dietz syndrome in comparison with Marfan syndrome

    International Nuclear Information System (INIS)

    Loeys-Dietz syndrome (LDS) is a connective tissue disease caused by mutations in the genes encoding the transforming growth factor-β receptor (TGFBR). LDS is associated with aneurysms or dissections of the aorta similar to Marfan syndrome (MFS) as well as arterial tortuosity and aneurysms in the peripheral arteries. The purpose of this study was to evaluate the arterial diseases of LDS to differentiate it from MFS. A total of 10 LDS patients with an identified mutation in TGFBR (6 male, 4 female; mean age 36.3 years) and 20 MFS patients with an identified mutation in fibrilin-1 who were age- and sex-matched to the LDS subjects (12 male, 8 female; mean age 37.1 years) were reviewed. The prevalence of vertebral arterial tortuosity (VAT) and peripheral aneurysm (PAN) was studied using computed tomography angiography. In all, 9 of the 10 LDS patients had VAT, and five PANs were observed in 3 patients. In contrast, 8 (40%) of the MFS patients had VAT, and 1 patient had a PAN. LDS had a higher prevalence of VAT (P=0.017) by Fisher's exact test. The VAT was highly prevalent among LDS patients. Thus, the presence of VAT has the potential to differentiate LDS from MFS.

    The landmark 1933 case report from Massachusetts General Hospital by Bland, White and Garland (Am Heart J 8:787-801) described a 3-month-old child with progressive feeding problems, cardiomegaly on chest radiography, and EKG evidence of left ventricular damage. Of interest was the fact that the vigilant father of the infant was Aubrey Hampton, a radiologist and future chairman of radiology at Massachusetts General Hospital. At autopsy, the left coronary artery originated from the pulmonary artery rather than from the aorta. Effective treatment for this condition was not available until 1960 when Sabiston, Neill and Taussig showed that the blood flowed from the left coronary artery toward the pulmonary artery. The anomalous left coronary artery was ligated at its junction with the pulmonary artery and the child survived. This historical review of Bland-White-Garland syndrome, now known as anomalous left coronary artery arising from the pulmonary artery (ALCAPA), stresses the continued diagnostic significance of cardiomegaly on chest radiography and EKG changes suggesting left ventricular damage in 2- to 3-month-old infants with feeding intolerance or irritability. With a high index of suspicion, an echocardiogram can be obtained to confirm the diagnosis. Modern surgical methods involve left coronary artery translocation and afford excellent outcomes. (orig.)

The Results of this study was found to be highly increased in the males than the females. The prevalence of metabolic syndrome in all of the participants was 30.5 percentages. The carotid artery IMT in the subjects with metabolic syndrome was significantly high in both genders, compared to the rest, who were without metabolic syndrome. The Pearsons correlation coefficient of metabolic syndrome and CIMT was 0.378(p<0.01). In conclusions, the present study also supports the association between the carotid artery IMT and the metabolic syndromes with cardiovascular risk factors. Usage of B-mode ultrasonography to measure the carotid artery IMT was found to be highly effective in the current analysis.

  10. Prevalence of coronary artery disease in Japanese patients with cerebral infarction. Impact of metabolic syndrome and intracranial large artery atherosclerosis

    International Nuclear Information System (INIS)

    Patients with cerebral infarction have a high prevalence of asymptomatic coronary artery disease (CAD) and other vascular diseases, but there is a lack of such data for Japanese patients, so the present study investigated the prevalence of cardiovascular disease (CVD) in Japanese patients and determined the predictors of CAD. The study group comprised 104 patients with cerebral infarction who had no history of CVD. All patients underwent coronary computed tomographic angiography, and systematic evaluation was done on the basis of the presence of other vascular diseases, CVD risk markers, and the degree of atherosclerosis. Of the total, 39 patients (37.5%) had CAD, 9 (8.7%) had carotid artery stenosis, 9 (8.7%) had peripheral artery disease of the lower limbs, and 3 (2.9%) had atherosclerotic renal artery stenosis. Multiple regression analysis showed that the presence of CAD was independently associated with metabolic syndrome (odds ratio (OR) 5.008, 95% confidence interval (CI) 1.538-16.309; p<0.01) and intracranial large artery atherosclerosis (OR 4.979, 95% CI 1.633-15.183; p<0.01). Japanese patients with cerebral infarction have a high prevalence of CVD, especially asymptomatic CAD. Both metabolic syndrome and intracranial large artery atherosclerosis may be potential predictors for identifying patients with cerebral infarction who are at the highest risk of asymptomatic CAD.

    Full Text Available Abstract Introduction Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction resulting from compression of the duodenum by the superior mesenteric artery and abdominal aorta. Case presentation We describe a case of superior mesenteric artery syndrome in a 61-year-old Japanese man with non-small cell lung cancer who had been treated with cisplatin-containing chemotherapy and had lost 7 kg in weight. The diagnosis was confirmed by the typical findings of abdominal computed tomography showing distended stomach resulting from compression of the third portion of the duodenum and reduction of an aortomesenteric distance and aortomesenteric angle. Conclusions This case highlights the importance of considering the possibility of superior mesenteric artery syndrome in patients treated with chemotherapy, especially those presenting with a low body mass index and showing weight loss during chemotherapy.

    During a 3-year period, three patients developed arterial complications related to congenital or post-traumatic old pseudarthrosis of the clavicle. Arterial complications of pseudarthrosis of the clavicle presenting as a thoracic outlet syndrome are very rare. Symptoms are variable and occur late. Without treatment, the prognosis is poor with spontaneous development of gangrene. Arterial morphology investigations should be undertaken in patients with pseudarthrosis of the clavicle or isolated arterial symptoms involving the upper limb whose radial pulse disappears during postural tests. Duplex Doppler of the subclavian artery is an excellent screening exam but selective arteriography is the gold standard. It shows proximal arterial lesions (embolytic stenosis of the subclavian artery with post-stenotic dilatation), as well as distal embolic complications. Both static and postural tests must be performed to unmask subclavian restriction by the clavicle, proving its causal effect in the arterial complications. There are four clinical varieties: chronic thrombosis of the subclavian artery, distal arterial micro emboli, acute thrombosis of proximal arteries of the upper limb, and subclavian aneurysm. These lesions are thought to be due to chronic constriction and repeated arterial microtrauma. Congenital or post-traumatic pseudarthrosis, hypertrophic callus, arterial restriction by a screw in a clavicular plate, usually explain the arterial lesions. Bone tumors and Paget's disease are potential but exceptional clavicular etiologies. Surgical treatment is always necessary. Clavicular resection is usually needed in case of pseudarthrosis; there is no functional handicap. Plate fixation and autologous grafting, or open reduction and internal fixation are other valid surgical treatments; The embolytic lesions must be treated to prevent recurrence of distal embolization: graft resection and thromboendarteriectomy have been described.

    Full Text Available Background: Pseudoexfoliation syndrome (PEX is recognised by chronic deposition of abnormal pseudoexfoliation material on anterior segment structures of the eye, especially the anterior lens capsule. In recent years, several studies have shown the presence of vascular, cardiac and other organ pseudoexfoliative material in patients with ocular pseudoexfoliation. Aims : The purpose of this study is to determine whether an association exists between ocular pseudoexfoliation and coronary artery disease, aortic aneurysms and peripheric vascular disease. Patients and Methods: 490 patients who underwent coronary angiography (CAG at Kosuyolu Cardiovascula Research and Training Hospital were included in the study. Patients were evaluated for conventional risk factors such as age, sex, family history, hypertension, diabetes, dislipidemia and smoking. Detailed eye examinations including evaluation of lens were done in all patients. The presence of PEX material in the anterior segment was best appreciated by slit lamp after pupillary dilation. The patients were divided into two groups according to the presence of PEX, and compared for the presence of CAD and other risk factors. Results: CAD was present in 387 patients. 103 patients had normal coronary angiography. 20 (5.2 % of CAD patients and 4 (3.9% of normal CAG patients were found to have PEX (p>0.05. There was no significant relationship between CAD and the presence of PEX (p>0.05. When patients were grouped according to the presence of PEX, only age was significantly different between the two groups (r: 0.25, p<0.001. Conclusion: There is no significant relationship between the presence of PEX and CAD. Further studies in larger scales with elderly population may be more valuable.

    Arterial tortuosity syndrome (ATS) is a rare hereditary disorder with variable clinical presentation including tortuosity and elongation of the major arteries, often associated with pulmonary artery stenosis, pulmonary hypertension, and skin and joint laxity, suggestive of a connective tissue disorder. ATS is transmitted in an autosomal recessive mode, but the causal gene is unknown. We report an Italian pedigree with three inbred families in which five patients show signs of ATS. In particular, four adult patients present arterial tortuosity and elongation of the main arteries. Two of these patients, with the most severe degree of arterial tortuosity, also show severe peripheral stenosis of the main pulmonary artery. The fifth young patient shows a severe pulmonary valve stenosis in the absence of arterial tortuosity. All patients show signs of Ehlers-Danlos syndrome (EDS): soft skin with abundant subcutaneous tissue and joint laxity, hernias, and disorganization of the extracellular matrix (ECM) of fibronectin (FN) and of actin microfilaments in cultured skin fibroblasts. Linkage analysis of the genes involved in EDS and other connective tissue disorders, excluded COL1A1, COL1A2, COL2A1, COL3A1, COL5A1, COL5A2, COL5A3, COL6A1, COL6A2, ADAMTS2, ELN, FN1, TNXA, and TNXB as candidate genes in the family under study, thus indicating that ATS is a distinct clinical and molecular entity.

    We report a case of left upper cervical posterior spinal artery (PSA) syndrome caused by atherosclerosis of the left vertebral artery. A 70-year-old female experienced sudden dizziness and paralysis of the left upper and lower limbs. Diffusion-weighted magnetic resonance imaging (DWI) of the brain showed high signal intensity at the vermis and lower left hemisphere of the cerebellum, and magnetic resonance angiography showed that the entire left vertebral artery was thin. The patient was treated with an intravenous infusion of tissue plasminogen activator 2 hours after symptom onset and made a full recovery. Repeat DWI, fluid-attenuated inversion recovery images, and T2-weighted images showed high signal intensity in the left upper cervical PSA area from the lower medulla oblongata to the C2 level in addition to the cerebellum. Previously reported cases of cervical posterior artery syndrome are reviewed. PMID:27012218

    Full Text Available We describe an infant presenting with contractures of the fingers, a large ventricular septal defect (VSD, and severe pulmonary artery dilatation. He had clinical and echocardiographic features of both neonatal or infantile Marfan syndrome (MFS and congenital contractural arachnodactyly. After surgical VSD closure, the aortic root developed progressive dilatation while the size of pulmonary artery returned to normal limits. Eventually the diagnosis of MFS was confirmed by DNA analysis.

    Full Text Available To our knowledge, incomplete central retinal artery occlusion associated with short posterior ciliary artery occlusion is extremely rare. Herein, we describe a case of a 62-year-old man who was referred to our hospital with of transient blindness in his right eye. At initial examination, the patient’s best-corrected visual acuity was 18/20 in the right eye. Fundus examination showed multiple soft exudates around the optic disc and mild macular retinal edema in his right eye; however, a cherry red spot on the macula was not detected. Fluorescein angiography revealed delayed dye inflow into the nasal choroidal hemisphere that is supplied by the short posterior ciliary artery. The following day, the patient’s visual acuity improved to 20/20. Soft exudates around the optic disc increased during observation and gradually disappeared. His hemodynamic parameters revealed subclavian steal syndrome as examined by cervical ultrasonography and digital subtraction angiography. We speculate that his transient blindness was due to ophthalmic artery spasms. In this particular case, spasms of the ophthalmic artery and occlusion of the short posterior ciliary artery occurred simultaneously. As the short posterior ciliary artery branches from the ophthalmic artery, the anatomical location of the lesion might be near the branching of both arteries.

    Full Text Available A 39-year-old woman presented with a right-hemispheric stroke 1 year after she had suffered a left-hemispheric stroke. Her diagnostic workup was notable for bilateral occlusions of the internal carotid arteries at their origins and a positive lupus anticoagulant antibody test. There was no evidence of carotid dissection or another identifiable cause for her carotid occlusions. These findings suggest that the antiphospholipid antibody syndrome may be implicated in the pathological changes that resulted in occlusions of the extracranial internal carotid arteries. Young stroke patients who present with unexplained internal carotid artery occlusions may benefit from testing for the presence of antiphospholipid antibodies.

    Congenital single coronary artery is commonly associated with complex congenital heart diseases and manifests in infancy or childhood. But isolated single coronary artery is a rare congenital anomaly which can present as acute coronary syndrome in adults. The aim of the work is to discuss on isolated single coronary artery in two adults presenting as acute coronary syndrome. The first case underwent coronary angiography (CAG) through right radial route, but switched over to femoral for confirmation of diagnosis and due to radial spasm. An aortic root angiogram was done to rule out presence of any other coronary ostia. It revealed a single coronary artery originating from right sinus of valsalva. After giving rise to posterior descending artery branch at crux, it continued in the atrioventricular groove to the anterior basal surface of the heart and traversed as anterior descending artery. There was no atheromatous occlusive stenosis. This is R-I type single coronary artery as per Lipton classification. In the second case, angiography was completed through right radial route. It revealed a single coronary artery arising from right aortic sinus. Anterior descending and circumflex branch were originating from proximal common trunk of the single coronary artery and supplying the left side of the heart. The right coronary artery has diffuse atheromatous disease without significant stenosis in any major branch. This is R-III C type as per Lipton classification. A coronary anomaly of both origin and course is very rare. It may be encountered in adults evaluated for atherosclerotic coronary heart disease. Knowledge and understanding of anatomical types of this congenital anomaly will reduce time, anxiety, complications during CAG and cardiac surgery. PMID:25075168

    Full Text Available True spontaneous coronary artery dissection (SCAD is an extremely rare but important cause of acute coronary syndrome, with only about 200 cases reported in the literature. Diagnosis is often made at autopsy. Risk factors include oral contraceptive use, atherosclerotic disease and the peripartum period. SCAD should be considered when a healthy young patient presents with the onset of acute myocardial ischemic syndrome. A timely diagnosis and intervention are mandatory as SCAD can cause sudden death. We present a case of SCAD with an uncommon clinical presentation of acute coronary syndrome and without identifiable risk factors, and successfully treated with non-invasive (medical therapy.

  2. CT perfusion assessment of Moyamoya syndrome before and after direct revascularization (superficial temporal artery to middle cerebral artery bypass)

    International Nuclear Information System (INIS)

    To evaluate the utility of CT perfusion (CTP) for the assessment of superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis in patients with Moyamoya syndrome (MMS). Twenty-four consecutive MMS patients, who underwent unilateral STA-MCA bypass surgery, received CTP before and after surgery. The relative perfusion parameter values of surgical hemispheres before treatment were compared with post-treatment values. All patients underwent CT angiography (CTA) before and after surgery in order to confirm the patency of bypass. The follow-up CTA after surgery clearly demonstrated 20 (20/24, 83.3 %) bypass arteries, whereas four (16.7 %) bypass arteries were occluded or very small. Postoperative rMTT and rTTP values (P < 0.05) of the surgical side were significantly lower than pre-operation. In patients (n = 20) with bypass patency, postoperative rCBF, rMTT and rTTP values (P < 0.05) of the surgical side were significantly improved. However, the differences of all parameters were not significant (P > 0.05) in the patients (n = 4) without bypass patency after revascularization. This study demonstrates that CTP can provide a crucial quantitative assessment of cerebral haemodynamic changes in MMS before and after STA-MCA anastomosis. (orig.)

    Background Pulmonary arterial hypertension, also known as Ascites syndrome (AS), remains a clinically challenging disease with a large impact on both humans and broiler chickens. Pulmonary arterial remodeling presents a key step in the development of AS. The precise molecular mechanism of pulmonary artery remodeling regulating AS progression remains unclear. Methodology/Principal Findings We obtained pulmonary arteries from two positive AS and two normal broilers for RNA sequencing (RNA-seq) analysis and pathological observation. RNA-seq analysis revealed a total of 895 significantly differentially expressed genes (DEGs) with 437 up-regulated and 458 down-regulated genes, which were significantly enriched to 12 GO (Gene Ontology) terms and 4 KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways (Padj<0.05) regulating pulmonary artery remodeling and consequently occurrence of AS. These GO terms and pathways include ribosome, Jak-STAT and NOD-like receptor signaling pathways which regulate pulmonary artery remodeling through vascular smooth cell proliferation, inflammation and vascular smooth cell proliferation together. Some notable DEGs within these pathways included downregulation of genes like RPL 5, 7, 8, 9, 14; upregulation of genes such as IL-6, K60, STAT3, STAT5 Pim1 and SOCS3; IKKα, IkB, P38, five cytokines IL-6, IL8, IL-1β, IL-18, and MIP-1β. Six important regulators of pulmonary artery vascular remodeling and construction like CYP1B1, ALDH7A1, MYLK, CAMK4, BMP7 and INOS were upregulated in the pulmonary artery of AS broilers. The pathology results showed that the pulmonary artery had remodeled and become thicker in the disease group. Conclusions/Significance Our present data suggested some specific components of the complex molecular circuitry regulating pulmonary arterial remodeling underlying AS progression in broilers. We revealed some valuable candidate genes and pathways that involved in pulmonary artery remodeling further contributing to the AS

    AIM: To study the effect of oral garlic on arterial oxygen pressure in children with hepatopulmonary syndrome.METHODS: Garlic powder in a capsule form was given to 15 children with hepatopulmonary syndrome (confirmed by contrast echocardiography) at the dosage of 1g/1.73 m2 per day. Patients were evaluated clinically and by arterial blood gas every four weeks.RESULTS: The garlic capsule was administered to 15patients with hepatopulmonary syndrome. There were 10 boys and 5 girls with a mean age of 9.4±3.9 years.The underlying problems were biliary tract atresia (4patients), autoimmune hepatitis (4 patients), cryptogenic cirrhosis (4 patients) and presinusoidal portal hypertension (3 patients). Eight patients (53.3%) showed an increase of 10 mmHg in their mean arterial oxygen pressure. The baseline PaO2 was 65.6±12.1 mmHg in the responder group and 47.1±11.2 mmHg in nonresponder group. At the end of treatment the mean PaO2 in responders and non-responders was 92.2±7.75mmHg and 47.5±11.87 mmHg, respectively (P<0.01).CONCLUSION: Garlic may increase oxygenation and improve dyspnea in children with hepatopulmonary syndrome.

    For patients with a non-ST-segment elevation acute coronary syndrome (NSTE-ACS), guideline recommendations and treatment pathways focus on revascularization for definitive treatment if the patient is an appropriate candidate. Despite the widespread use of revascularization for NSTE-ACS, most patients undergo a percutaneous coronary intervention, whereas a minority of patients undergo coronary artery bypass grafting. Focusing specifically on the USA, the contemporary utilization, preoperative and perioperative considerations, and outcomes of NSTE-ACS patients undergoing coronary artery bypass grafting have not been comprehensively reviewed.

    Williams syndrome (WS) is a developmental disorder characterized by vascular abnormalities such as thickening of the vascular media layer in medium- and large-sized arteries. Supravalvular aortic stenosis (SVAS) and peripheral pulmonary artery stenosis (PPAS) are common vascular abnormalities in WS. The natural course of SVAS and PPAS is variable, and the timing of surgery or intervention is determined according to the progression of vascular stenosis. In our patient, SVAS and PPAS showed rapid concurrent progression within two weeks after birth. We report the early manifestation of SVAS and PPAS in the neonatal period and describe the surgical treatment for stenosis relief. PMID:27066434

    The Korsakoff syndrome is defined as "an abnormal mental state in which memory and learning are affected out of all proportion to other cognitive functions in an otherwise alert and responsive patient." Confabulation refers to false or erroneous memories arising, not deliberately, in the context of a neurological amnesia and is often thought of as pathognomonic of the Korsakoff syndrome. Although the exact pathophysiology is unknown, various studies have identified brain lesions in the thalami, mammillary bodies, and frontal cortex. We report a case of a 68-year-old male presenting with acute altered mental status on July 16, 2015. The neuropsychological dysfunctions included prominent Korsakoff's syndrome, which became apparent when the altered mental status resolved. Amnesia was accompanied by prominent confabulation, disorientation, and lack of insight into his own disability. Neuroradiological data indicated that the intralaminar and dorsomedial nuclei in bilateral thalami were infarcted by occlusion of the artery of Percheron. We believe that ours is one of few reported cases of Korsakoff syndrome in a patient with infarction involving the territory of the artery of Percheron.

    Full Text Available The Korsakoff syndrome is defined as “an abnormal mental state in which memory and learning are affected out of all proportion to other cognitive functions in an otherwise alert and responsive patient.” Confabulation refers to false or erroneous memories arising, not deliberately, in the context of a neurological amnesia and is often thought of as pathognomonic of the Korsakoff syndrome. Although the exact pathophysiology is unknown, various studies have identified brain lesions in the thalami, mammillary bodies, and frontal cortex. We report a case of a 68-year-old male presenting with acute altered mental status on July 16, 2015. The neuropsychological dysfunctions included prominent Korsakoff’s syndrome, which became apparent when the altered mental status resolved. Amnesia was accompanied by prominent confabulation, disorientation, and lack of insight into his own disability. Neuroradiological data indicated that the intralaminar and dorsomedial nuclei in bilateral thalami were infarcted by occlusion of the artery of Percheron. We believe that ours is one of few reported cases of Korsakoff syndrome in a patient with infarction involving the territory of the artery of Percheron. We conclude that bilateral thalamic lesions could cause Korsakoff’s syndrome and the intralaminar and dorsomedial nuclei might be important structures in the pathogenesis of confabulation.

  11. Radiocephalic Fistula Complicated by Distal Ischemia: Treatment by Ulnar Artery Dilatation

    International Nuclear Information System (INIS)

    Hand ischemic steal syndrome due to a forearm arteriovenous fistula is a rare occurrence. However, its frequency is increasing with the rise in numbers of elderly and diabetic patients. This complication, which is more common for proximal than for distal accesses, can be very severe and may cause loss of hand function, damage to fingers, and even amputation of fingers or the hand. Its treatment is difficult and often leads to access loss. We report here a case of severe hand ischemia related to a radiocephalic fistula successfully treated by ulnar artery dilatation.

    2012-12-15

    Neurovascular compression is assumed to cause symptoms like trigeminal neuralgia, hemifacial spasm and vestibular paroxysmia. We present a patient with recurrent episodes of transient dysarthria due to isolated right hypoglossal nerve (HN) palsy. We describe the first case of a calcified persistent hypoglossal artery (PHA) as the putative cause of a hypoglossal neurovascular compression syndrome. Our patient received a daily low-dose medication of carbamazepine resulting in complete relief of symptoms. In conclusion, PHA is not only an anatomic variation but also a possible cause of a neurovascular compression syndrome leading to intermittent HN palsy. PMID:23020989

  15. A patient with WPW syndrome and coronary artery disease

    International Nuclear Information System (INIS)

    A 61-year-old patient with Wolff-Parkinson-White's syndrome, and hypertension was admitted to the CCU, because of the first episode of substernal chest pain. ECG was deformed by Wolff-Parkinson-White's syndrome, type B, with accessory pathway located on the right side, without evolution. Serum enzymes remained low. Echocardiography showed akinesis of the posterior wall and hypokinesis of the lateral wall (the same contraction disorders were described in previous echocardiographical examination 5 years ago), it was observed that the first portion of myocardium to contract was the base of the right ventricle. To elucidate the etiology of the contraction disorders, scintigraphy of the heart, using thallium 201, was performed, showing normal perfusion of the myocardium. To illustrate the dependence of the contraction disorders and abnormal depolarization pattern of the heart, echocardiographical examination was repeated, confirming the previous results, then 100 mg of Ajmaline was given to the patient intravenously, and echocardiographical examination was continued. Administration of the drug caused antidromic atrioventricular re-entrant tachycardia during which the lateral wall of the heart had been contracting properly. This case shows contraction disorders of the heart caused by the abnormal depolarization pattern, resulting from the presence of accessory pathway. It also illustrates the diagnostic difficulties in patients with Wolff-Parkinson-White's syndrome and suspected myocardial infarction, at the same time showing that scintigraphy of the heart might be very helpful in such patients. This case confirms the usefulness of echocardiography for localization of the accessory pathway. (author)

  16. MRI of anterior spinal artery syndrome of the cervical spinal cord

    International Nuclear Information System (INIS)

    Cervical spinal cord lesions in the anterior spinal artery syndrome were delineated on magnetic resonance images (MRI) in four patients. The lesion was always seen anteriorly in the cervical cord. On T2-weighted images, the lesions appeared hyperintense relative to the normal spinal cord, while on T1-weighted images, two chronic lesions appeared hypointense, with local atrophy of the cord. In one case, repeated T1-weighted images showed no signal abnormality 4 days after the ictus, but the lesion became hypointense 18 days later, when contrast enhancement was also recognized after injection of Gd-DTPA; this sequence of intensity changes was similar to that of cerebral infarction. The extent of the lesion seen MRI correlated closely with neurological findings in all cases. Although the findings may not be specific, MRI is now the modality of choice for confirming the diagnosis in patients suspected of having an anterior spinal artery syndrome. (orig.)

    2010-08-01

    Full Text Available Abstract Background Accumulation of oxidized low-density lipoproteins in the intimae of arteries and endothelial dysfunction are key events in the development of atherosclerosis. Patients with metabolic syndrome are at high risk for cardiovascular diseases but the linkage between metabolic syndrome and atherosclerosis is incompletely understood. We studied whether the levels of oxidized LDL and arterial elasticity differ between metabolic syndrome patients and physically active controls. Methods 40 men with metabolic syndrome and 40 physically active controls participated in this cross-sectional study. None of the study subjects had been diagnosed with cardiovascular disease. Levels of oxidized LDL were assessed by a two-site ELISA immunoassay. Arterial elasticity was assessed non-invasively by the HDI/PulseWave™ CR-2000 arterial tonometer. Results Levels of oxidized LDL were 89.6 ± 33.1 U/L for metabolic syndrome subjects and 68.5 ± 23.6 U/L for controls (p = 0.007. The difference remained significant after adjustment for LDL cholesterol. Large artery elasticity index (C1 was 16.2 ± 4.1 mL/mmHgx10 for metabolic syndrome subjects and 19.4 ± 3.7 mL/mmHgx10 for controls (p = 0.001, small artery indices (C2 were 7.0 ± 3.2 mL/mmHgx100 and 6.5 ± 2.9 mL/mmHgx100 (NS, respectively. Conclusions Subjects with metabolic syndrome had elevated levels of oxidized LDL and reduced large arterial elasticity compared to controls. This finding may partly explain the increased risk for cardiovascular diseases among metabolic syndrome patients. Trial registration ClinicalTrials.gov NCT01114763

    PurposeTo evaluate the safety and efficacy of transarterial embolization of life-threatening arterial rupture in patients with vascular Ehlers–Danlos syndrome (vEDS) in a single tertiary referral center.MethodsWe retrospectively analyzed transarterial embolization for vEDS performed at our institution from 2000 to 2012. The indication of embolization was spontaneous arterial rupture or pseudoaneurysm with acute bleeding. All interventions used a percutaneous approach through a 5F or less introducer sheath. Embolic agents were microcoils and glue in 3 procedures, glue alone in 2, and microcoils alone in 2.ResultsFive consecutive vEDS patients were treated by 7 embolization procedures (4 women, mean age 29.8 years). All procedures were successfully performed. Two patients required a second procedure for newly arterial lesions at a different site from the first procedure. Four of the five patients were still alive after a mean follow-up of 19.4 (range 1–74.7) months. One patient died of multiple organ failure 2 days after procedure. Minor procedural complications were observed in 3 procedures (43 %), all directly managed during the same session. Remote arterial lesions occurred after 3 procedures (43 %); one underwent a second embolization, and the other 2 were observed conservatively. Puncture site complication was observed in only one procedure (14 %).ConclusionEmbolization for vEDS is a safe and effective method to manage life-threatening arterial rupture.

We describe the case of a 54-year-old woman with eosinophilia and involvement of the respiratory tract, skin, and peripheral nervous system, fulfilling the American College of Rheumatology criteria for Churg-Strauss syndrome. The patient presented with acute, painless vision loss in her right eye. Central retinal artery occlusion (CRAO without accompanying retinal vasculitis was diagnosed by angiographic findings and funduscopic findings of retinal whitening with a cherry-red spot. Although her antineutrophil cytoplasmic antibody (ANCA status was negative, CRAO was thought to be an ocular manifestation of Churg-Strauss syndrome, and appropriate treatment was planned. She was treated with high-dose corticosteroids and anticoagulant therapy. Her macular edema improved, but visual recovery was poor. Specific therapy to alter inflammation, blood coagulation, and rheology reportedly plays an important role in ANCA-positive patients with Churg-Strauss syndrome who develop CRAO. Regardless of ANCA status, high-dose corticosteroids should be considered for CRAO in patients with Churg-Strauss syndrome, as discussed in this case.Keywords: CRAO, ANCA, Churg-Strauss syndrome

  9. Splenic Artery Syndrome After Orthotopic Liver Transplantation: Treatment With the Amplatzer Vascular Plug

    International Nuclear Information System (INIS)

    Purpose: To evaluate the safety and efficacy of the Amplatzer vascular plug (AVP) for embolization of the splenic artery in patients with hepatic hypoperfusion after orthotopic liver transplantation (OLT). Materials and Methods: Thirteen patients (9 men and 4 women) with a mean age of 56 years (range 22–70) who developed splenic artery syndrome after OLT with decreased liver perfusion and clinically relevant impairment of liver function (increased transaminase or serum bilirubin levels, thrombocytopenia, and/or therapy-refractory ascites) were treated by embolization of the proximal third of the splenic artery using the AVP. The plugs ranged in diameter from 6 to 16 mm, and they were introduced through femoral (n = 9), axillary (n = 3), or brachial (n = 1) access using a 5F or 8F guiding catheter. Results: The plugs were successfully placed, and complete occlusion of the splenic artery was achieved in all patients. Placement of two plugs was necessary for complete occlusion in 3 of the 13 patients. Occlusion took on average 10 min (range 4–35). There was no nontarget embolization or plug migration into more distal segments of the splenic artery. All patients showed improved arterial perfusion, including the liver periphery, on postinterventional angiogram. After embolization, liver function parameters (transaminase and bilirubin levels) improved with normalization of concomitant thrombocytopenia and a decrease in ascites volume. Conclusion: Our initial experience in a small patient population with SAS suggests that the AVP enables precise embolization of the proximal splenic artery, thus providing safe and effective treatment for poor liver perfusion after OLT due to SAS.

    Horner syndrome, a triad of ptosis, anisocoria, and anhidrosis, results from interruption in the oculosympathetic pathway. It is classically described as either congenital or acquired to depict its underlying pathophysiology and requisite work-up. We report a case of a 10-month-old infant presenting with an acute onset of left Horner syndrome secondary to a spontaneous extracranial internal carotid artery dissection. To the best of our knowledge, this is the first case report in the literature of acute onset of acquired infantile Horner syndrome in association with spontaneous carotid artery dissection confirmed with magnetic resonance angiogram.

    Full Text Available Behçet’ s disease is a systemic autoimmune vasculitis of unknown etiology. It causes serious disability by affecting both arteries and veins. Hoarseness due to compression of the left recurrent laringeus nerve resulting from pathologies of the heart and intrathoracic great vessels is defined as Ortner’s syndrome. The most common cause of Ortner’s syndrome is left atrial enlargement due to mitral stenosis. Various intrathoracic pathologies may also be the reason. Beside, Ortner’s syndrome due to primary pulmonary artery aneurysm as a feature of Behçet’s disease is relatively rare. Herein, we report a case of a 78 year old female patient presenting with hoarseness and diagnosed as Ortner’s syndrome resulting from a giant pulmonary artery aneurysm secondary to Behçet’ s disease.

    2007-01-01

    The association of metabolic syndrome (MS)with arterial compliance in children and adolescents was explored.337 subjects (188 men and 149 women) aged 6-18 (10.95±3.01) years,out of "Beijing Child Metabolic Syndrome Study",were divided into three ease groups (one component,two components,three & more components of MS) and one control group based on the Cook's MS definition in children and adolescents.Measurements including anthropometry,blood pressure,fasting plasma glucose and insulin,serum lipid profile were done.Homeostasis model assessment for insulin resistance (HOMA-IR) index was calculated for estimating individual insulin resistance.Arterial compliance was measured using digital pulse wave analyzing method from the pulse trace machine (Micro medical,London),and then the stiffness index (SI) was determined.The mean value of SI in MS group was significant higher than that in control group [(7.69±1.63) vs (6.25 + 0.86) m/s,P < 0.01 ].With the increase of the clustering of MS components,SI and HOMA-IR were gradually increased.After taking account of gender,age and pubertal development,the partial correlation analysis showed that the amount of components of MS and HOMA-IR were positively correlated with SI (both P values were less than 0.05).The arterial compliance of MS group was significantly lowered in children and adolescents,and with the increase of the clustering of MS components,arterial compliance was gradually decreased.It was suggested that arterial compliance assessment in children and adolescents was important for early prevention of cardiovascular diseases.

    2012-12-01

    Carpal tunnel syndrome is the most frequent neuropathy of the upper extremity, that mainly occurs in manual workers and individuals, whose wrist is overloaded by performing repetitive precise tasks. In the past it was common among of typists, seamstresses and mechanics, but nowadays it is often caused by long hours of computer keyboard use. The patient usually complains of pain, hypersensitivity and paresthesia of his hand and fingers in the median nerve distribution. The symptoms often increase at night. In further course of the disease atrophy of thenar muscles is observed. In the past the diagnosis was usually confirmed in nerve conduction studies. Nowadays a magnetic resonance scan or an ultrasound scan can be used to differentiate the cause of the symptoms. The carpal tunnel syndrome is usually caused by compression of the median nerve passing under the flexor retinaculum due to the presence of structures reducing carpal tunnel area, such as an effusion in the flexor tendons sheaths (due to overload or in the course of rheumatoid diseases), bony anomalies, muscle and tendon variants, ganglion cysts or tumors. In some cases diseases of upper extremity vessels including abnormalities of the persistent median artery may also result in carpal tunnel syndrome. We present a case of symptomatic carpal tunnel syndrome caused by thrombosis of the persistent median artery which was diagnosed in ultrasound examination. The ultrasound scan enabled for differential diagnosis and resulted in an immediate referral to clinician, who recommended instant commencement on anticoagulant treatment. The follow-up observation revealed nearly complete remission of clinical symptoms and partial recanalization of the persistent median artery. PMID:26676173

    2015-12-01

    Superior mesenteric artery (SMA) syndrome is defined as a compression of the third portion of the duodenum by the abdominal aorta and the overlying SMA. SMA syndrome associated with anorexia nervosa has been recognized, mainly among young female patients. The excessive weight loss owing to the eating disorder sometimes results in a reduced aorto-mesenteric angle and causes duodenal obstruction. Conservative treatment, including psychiatric and nutritional management, is recommended as initial therapy. If conservative treatment fails, surgery is often required. Currently, traditional open bypass surgery has been replaced by laparoscopic duodenojejunostomy as a curative surgical approach. However, single incision laparoscopic approach is rarely performed. A 20-year-old female patient with a diagnosis of anorexia nervosa and SMA syndrome was prepared for surgery after failed conservative management. As the patient had body image concerns, a single incision laparoscopic duodenojejunostomy was performed to achieve minimal scarring. As a result, good perioperative outcomes and cosmetic results were achieved. We show the first case of a young patient with SMA syndrome who was successfully treated by single incision laparoscopic duodenojejunostomy. This minimal invasive surgery would be beneficial for other patients with SMA syndrome associated with anorexia nervosa, in terms of both surgical and cosmetic outcomes. PMID:26668518

    Background There is significant evidence showing that microalbuminuria and arterial compliance are sensitive markers for early cardiovascular diseases. However, whether microalbuminuria is associated with reduced arterial compliance in Chinese metabolic syndrome (MS) patients remains unknown.Methods According to the definition of MS proposed by ATPⅢ in 2001, USA, subjects (n=362) were divided into three groups according to the number of risk factors: group 1 (control), group 2 (medium, < 3 risk factors) and group 3 (MS, ≥ 3 risk factors). Both large artery compliance (C1) and small artery compliance (C2) were measured with the CVProfilor DO-2020 Cardiovascular Profiling System, and microalbuminuria was evaluated with the ratio of albumin to urine creatinine.Results (1) As C1 and C2 levels elasticity decreased, albumin creatinine ratio (ACR) and the prevalence of microalbuminuria increased within those groups with MS risk factors. C1 and C2 were negatively correlated with the ranking of MS risk factors, ACR was positively correlated with the ranking of MS risk factors (all P<0.05). (2) Subjects were also categorized into a microalbuminuria group and a normal group, C1 and C2 in the microalbuminuria group were lower than in the normal group. (3) Multivariate regression analysis showed that increased systolic blood pressure (SBP) and reduced arterial compliance were the main risk factors for microalbuminuria in the MS group.Conclusions The risk of developing microalbuminuria was higher in the subjects with multiple metabolic abnormalities.Increased systolic blood pressure and reduced arterial compliance may be the main predictors for microalbuminuria in MS.

    We describe a 26-year-old white female with a history of Raynaud phenomenon, erythema nodosum, polyarthralgias, migraine, vertigo, seizures, transient ischemic attacks, one fetal loss, and false positive VDRL, who developed milk hypertension without overt lupus nephritis. She had positive antinuclear antibodies (ANA) and double-stranded deoxyribonucleic acid (dsDNA) antibodies. The lupus anticoagulant test (LAC) and cardiolipins antibodies (aCL) were positive. She was diagnosed as having a Systemic Lupus Erythematosus-like illness (SLE-like) with 'secondary' antiphospholipid syndrome (APS). Renal spiral computed tomography (CT) with intravenous (IV) contrast showed bilateral renal artery stenosis. Anticoagulation with acenocumarol was started. She became normotensive without antihypertensive drugs five months later. A follow-up renal spiral CT showed complete recanalization of both renal arteries, making thrombosis the more likely culprit pathology in the stenosis. After two years follow up the patient is normotensive. She remains on acenocumarol. PMID:10713649

    Full Text Available Ehlers-Danlos syndrome (EDS is a rare heterogeneous group of connective tissue disorders. The vascular type (vEDS is an autosomal dominant disorder caused by heterozygous mutations in the COL3A1 gene predisposing to premature arterial, intestinal, or uterine rupture. We report a case of a 38-year-old woman with a recent diagnosis of vEDS admitted in the Emergency Department with a suspicion of a pyelonephritis that evolved to a cardiopulmonary arrest. A fatal retroperitoneal hematoma related with a haemorrhagic dissection of the right renal artery was found after emergency surgery. This case highlights the need to be aware of the particular characteristics of vEDS, such as a severe vascular complication that can lead to a fatal outcome.

    @@ Coronary artery bypass grafting (CABG) is considered as a more complete means of revascularization than percutaneous coronary intervention (PCI). However, acute coronary syndrome (ACS) can still occur after CABG. The culprit vessel can be the graft vessel or the native vessel. Many questions remain unanswered in the Chinese literature regarding this topic: what are the short- and long-term pathological changes that induce ACS? Is there any difference between arterial and venous grafts with respect to the frequency of restenosis? Are there any patterns of ACS-related vessels in different periods after CABG? We aim to answer these fundamental questions by analyzing coronary angiographies of patients with recurrent ACS following CABG and provide evidence for reducing post-CABG restenosis.

    Full Text Available Horner's syndrome (HS is a sympathetic dysfunction caused by injuries to the sympathetic pathway. A clinical case of HS following common carotid artery transposition and catheterization in a horse is described. The animal presented head and neck sweating with focal skin temperature elevation, facial paralysis and ptosis. Most clinical signs were transient and persisted for two hours following percutaneous catheter removal. Recurrence of clinical signs was observed at subsequent catheterizations. Ptosis endured for 10 months as a consequence of the first catheter placement which demonstrates the importance of careful manipulation of the anatomical structures of the neck when performing any surgical manipulation in this area.

    Full Text Available ABSTRACT: AIM: To report a case of Central Retinal Artery Occlusi on (CRAO in young males in its initial manifestation as Primary Antiphospholipid Syndrome. METHODS: 32 year healthy male, with abrupt sudden painless loss of vision in r ight eye since 48 hours, with Grade 2 Relative afferent pupillary defect, visual acuity of hand movements in OD and 6/18 in OS. Fundoscopy disclosed signs compatible of central reti nal artery occlusion confirmed with FFA. Carotid Doppler imaging and echocardiography was done to determine the source. RESULTS: Antiphospholipid antibody cofactor, beta2-glycoprotein 1 antibodies, IgM, was positive with titre of more than 94 un its/ml on two occasions, 1 2 weeks apart, with normal range being less than 20 units/ml for each isotope (IgG, IgM, or IgA .According to the 2006 revised Sapporo criteria Antiphospholipid syndrome was diagnosed. Thor ough examination excluded other system involvement. Immunological studies excluded other systemic disorders. CONCLUSIONS: In literature, prevalence of CRAO is 0.85% for every 100000 and prevalence of Antiphospholipid Syndrome in patients showing a major retinal vascula r obstruction is 5% - 33%. Antiphospholipid syndrome should be ruled out in every young patient who presents with Central retinal artery occlusion. Association must be considered, as Central retinal artery occlusion could be the initial manifestation of ant iphospholipid syndrome with high risk of recurrence.

    Von Hippel-Lindau syndrome is a rare, genetically based, autosomal dominant disorder. Its course is accompanied by the development of multiple neoplasms with the following tumours diagnosed most commonly in the central nervous system haemangioblastoma, clear cell renal cell carcinoma, phaeochromocytomas, pancreatic islet tumours, and endolymphatic sac tumours. Additionally, renal and pancreatic cystadenomas and epididymal cystadenomas have been diagnosed in males and cystadenomas of the broad ligament of the uterus have been diagnosed in females.The following paper presents the diagnostic way in a boy with vision disorders as the first symptom. Hypertension retinopathy and extremely elevated blood pressure were observed during ophthalmologic consultation. Complications of arterial hypertension were confirmed by echocardiography, which diagnosed hypertension cardiomyopathy. Hypertension retinopathy was confirmed by optical coherence tomography. Examinations performed in the neurology, cardiology, and finally endocrinology indicated a bilateral phaeochromocytoma as the cause of arterial hypertension. Moreover, some genetic investigations showed a mutation in the VHL ex.1 p.Y112 C gene responsible for the hereditary form of phaeochromocytoma which confirmed von Hippel-Lindau syndrome. After surgical treatment of phaeochromocytoma the patient needed careful management according to the surveillance protocol for von Hippel-Lindau disease. PMID:26268347

  5. Association of increased triglyceride levels in metabolic syndrome with coronary artery disease

    International Nuclear Information System (INIS)

    Objective: We tried to understand significance of increased triglyceride (TG) values in metabolic syndrome and coronary artery disease (CAD). Methodology: Check up cases with a TG value lower than 60 mg/dL were collected into the first, between 60 and 99 mg/dL into the second, between 100 and 149 mg/dL into the third, between 150 and 199 into the fourth, and 200 mg/dL and greater into the fifth groups. Results: Study included 478 cases. Values of the mean age, weight, body mass index, TG, and low density lipoprotein cholesterol (LDL-C) and prevalence of smoking, white coat hypertension (WCH), hypertension (HT), type 2 diabetes mellitus (DM), and CAD increased gradually and significantly nearly in all steps from the first towards the fifth groups. Conclusion: Metabolic syndrome may be a progression step between complete physical health and irreversible end points, such as obesity, type 2 DM, HT, CAD, and stroke. Hypertriglyceridemia and White Coat Hypertension (WCH) may be the most significant reversible parameters of the syndrome, and it is better to have the lowest TG value as much as possible. The most significant increase was seen after the value of 100 mg/dL. The overweight, smoking, hypertriglyceridemia, hyperbetalipoproteinemia, and WCH may only be one of hundreds of parameters of the syndrome. Therefore, it is advisable that underlying etiologies rather than reversible parameters of the syndrome should be targeted for treatment. For example, increased TG and LDL-C values, and prevalence of WCH by aging may be secondary to decreased physical and mental stresses in elderly. (author)

  6. The application of interventional radiological procedures in treating hepatic artery complications occurred after liver transplantation

    International Nuclear Information System (INIS)

    Objective: To evaluate the interventional radiological procedures in treating hepatic artery complications occurred after liver transplantation. Methods: Thirteen patients with hepatic artery complications occurred after liver transplantation received interventional treatment. The interventional procedures included (1) percutaneous transarterial angioplasty (PTA) or endovascular stenting (ES) for 6 patients with hepatic artery stenosis (HAS) and for 3 patients with hepatic artery occlusion; (2) catheter-directed thrombolysis for 3 patients with hepatic artery thrombosis (HAT) and (3) coil embolization for one patient with gastroduodenal steal syndrome (GSS). Immediate, short-term and long-term effects were observed and evaluated. Results: The general immediate effective rate was 84.62% (11/13). The effective rate was 100% for HAS (6/6), HAT (3/3) and GSS (1/1). However, the effective rate for hepatic artery occlusion was only 33.3% (1/3). Color Doppler ultrasonography showed that the hepatic arterial flow remained fluent. Three days after the treatment statistically significant decrease in ALT (t=2.68, P<0.050) and T-BIL (t=2.94, P<0.05) was observed. No procedure-related complications or death occurred during the follow-up period of 2-34 months. Conclusion: As a safe, effective and minimally-invasive technique, interventional management can be regarded as the treatment of first choice for hepatic artery complications occurred after liver transplantation.

    Full Text Available Abstract Introduction Magnetic resonance imaging of the brain in patients with corticobasal degeneration typically shows focal or asymmetric atrophy, usually maximal in the frontoparietal cortex. Many patients who are diagnosed with corticobasal degeneration using current diagnostic criteria do not have classical corticobasal degeneration pathology. Our case is remarkable for the fact that the symptoms and the characteristic magnetic resonance imaging appearance were typical for corticobasal degeneration. However, we were quite convinced that the clinical picture had a vascular etiology. Only a few cases have been reported where the presumed cause for the corticobasal syndrome was multiple brain infarctions bilaterally. Case presentation A 64-year-old Caucasian man visited a neurologist because of profound asymmetric sensory and motor disturbances. A magnetic resonance imaging scan of his brain revealed occlusion of his internal carotid artery on the left side with multiple vascular lesions in his left hemisphere and notable atrophy of mainly the left parietal and frontal cortex. Conclusion We describe a patient with corticobasal syndrome caused by multiple infarctions, probably caused by emboli of the carotid stenosis. This patient illustrates the fact that the word 'syndrome' should be preferred above 'degeneration' in the name of this disease.

    Diffuse coronary arteries ectasia combined with calcification is seldom reported. Acute coronary syndrome, a potentially life-threatening disease, accompanied with coronary ectasia and diffuse calcification, made percutaneous coronary intervention difficult and risky owing to increasing complications rate. Dual-source computed tomography and three-dimensional volume rendering images help cardiovascular surgeon easier to localize the ideal site and facilitate the procedure.

    [Purpose] The purpose of this study was to investigate the effects of aerobic exercise on the resting heart rate, physical fitness, and arterial stiffness or female patients with metabolic syndrome. [Subjects and Methods] Subjects were randomly assigned to an exercise group (n=12) or a control group (n=11). Subjects in the exercise group performed aerobic exercise at 60-80% of maximum heart rate for 40 min 5 times a week for 12 weeks. The changes in metabolic syndrome risk factors, resting heart rate, physical fitness, and arterial stiffness were measured and analyzed before and after initiation of the exercise program to determine the effect of exercise. Arterial stiffness was assessed based on brachial-ankle pulse wave velocity (ba-PWV). [Results] Compared to the control group; The metabolic syndrome risk factors (weight, % body fat, waist circumference, systolic blood pressure, diastolic blood pressure, and HDL-Cholesterol) were significantly improved in the exercise: resting heart rate was significantly decreased; VO2max, muscle strength and muscle endurance were significantly increased; and ba-PWV was significantly decreased. [Conclusion] Aerobic exercise had beneficial effects on the resting heart rate, physical fitness, and arterial stiffness of patients with metabolic syndrome. PMID:27390411

    Full Text Available BACKGROUND: Coronary artery disease (CAD is the major determinant of preoperative morbidity and mortality for patients requiring major vascular surgery. The management of CAD in these patients is controversial. AIMS: The incidence and severity of CAD in diabetic and non-diabetic patients with Leriche syndrome was explored. SETTINGS AND DESIGN: 107 patients with Leriche syndrome were selected as major vascular occlusion and grouped according to their diabetic Status. Sex, age, dyslipidemia, obesity, hypertension, clinic cardiac status, coronary angiographic lesions and coronary revascularisation procedures were noted. MATERIAL & METHODS: Patients′ demographics, intra-operative and per-operative data were recorded and compared. In every patient with Leriche syndrome scheduled for elective vascular reconstruction coronary angiography was performed. Lesions were evaluated for the percentages of stenosis. Preliminary coronary bypass or percutaneous coronary intervention was recommended for those found to have advanced or severe CAD. Results of revascularisation procedures were compared. STATISTICAL ANALYSIS USED: Chi-square or Fisher exact chi-square test is used for conditional variables. Independent samples was analysed by using t-test. Kruskal-Wallis variance test was used if the variances are not homogeneous according to the Levene test. RESULTS: No difference was found in both groups except family history and obesity. Coronary angiographic investigation indicates that 59% of DIAB group and 38% of NONDIAB group patients have advanced or severe CAD which has a high probability for myocardial revascularization. Overall revascularisation rate is 37.8% in DIAB group and 45.7% in NONDIAB group (p=0,641. Preoperative mortality was found 2.7% in diabetics and 4.2% in non-diabetics (p=0.342. CONCLUSIONS: Leriche syndrome with diabetes mellitus is more likely to have advanced coronary disease than those without diabetes mellitus. Coronary angiography

    2014-01-01

    Splenomegaly is a common sequela of cirrhosis, and is frequently associated with decreased hematologic indices including thrombocytopenia and leukopenia. Partial splenic artery embolization (PSE) has been demonstrated to effectively increase hematologic indices in cirrhotic patients with splenomegaly. This is particularly valuable amongst those cirrhotic patients who are not viable candidates for splenectomy. Although PSE was originally developed decades ago, it has recently received increased attention. Presently, PSE is being utilized to address a number of clinical concerns in the setting of cirrhosis, including: decreased hematologic indices, portal hypertension and its associated sequela, and splenic artery steal syndrome. Following PSE patients demonstrate significant increases in platelets and leukocytes. Though progressive decline of hematologic indices occur following PSE, they remain improved as compared to pre-procedural values over long-term follow-up. PSE, however, is not without risk and complications of the procedure may occur. The most common complication of PSE is post-embolization syndrome, which involves a constellation of symptoms including fever, pain, and nausea/vomiting. The rate of complications has been shown to increase as the percent of total splenic volume embolized increases. The purpose of this review is to explore the current literature in regards to PSE in cirrhotic patients and to highlight their techniques, and statistically summarize their results and associated complications.

    2001-01-01

    Objective: To explore the patterns of Syndrome Differentiation (SD) of coronary heart disease (CHD) patients in peri-operative stage of coronary artery bypass graft (CABG). Methods: One week after operation, thirty-seven CHD patients, who received CABG of internal mammary artery or great saphena vein under conventional general anesthesia with low or middle temperature extracorporeal circulation were differentiated as various syndromes, with the pre- or post-operational EKG, color Doppler echocardiography were done during and after operation. The hemodynamic parameters were monitored. Results: In the CHD patients, 64.9% were differentiated as Qi-Yin deficiency, 67.6% were complicated with phlegm syndrome and 62.2% with blood stasis, suggesting that Qi-deficiency, phlegm and stasis are the basic pathogenetic factors in patients with CABG. Moreover, the peri-operative syndrome was correlated with the condition of coronary artery lesion, heart and lung functions before operation, and the extracorporeal circulation time during the operation. Conclusion: TCM SD conducting in peri-operative stage might be useful in exploring the patterns of syndrome alteration which provided a basis for preventing peri-operative complications and elevating success rate of operation.

    Full Text Available ABSTRACT We report one patient with Klippel-Feil (KFS syndrome, other associated anomalies, uncontrolled arterial hypertension, and renal artery stenosis. Because this patient underwent for surgical revascularization with unsuccessful result, all proposed way of treatments are revised, and we have hypothesized that probably for patients with KFS and unilateral renal artery stenosis, medical treatment with ACE inhibitors can provide more benefits than surgical revascularization or percutaneous transluminal angioplasty. We considered that those patients should be manage by a team of medical doctors being aware of their common associated anomalies, identifying all of them when it is possible then, making an integral evaluation of the each individual situation for establishing their medical priorities in order, and then address its treatments accordingly. If at this stage any surgical treatment is required, is important to bring those problems to the anesthesiologist’s attention for a very careful manipulation of the neck and head during induction of anesthesia. The final results will be strongly related with the capacity of management of the underlying cardio-respiratory, renal, skeletal, urogenital, and nervous system problems. . We also propose the term of Klippel-Feil syndrome "Plus" for those patients with cervical vertebral fusion and many other associated deformities rather than to add new eponyms to the long list that already exist. _____________ RESUMEN: HIPERTENSION RENOVASCULAR DEBIDO A ESTENOSIS DE LA ARTERIA RENAL EN EL SÍNDROME DE KLIPPEL-FEIL Reportamos un paciente afectado por un syndrome de Klippel-Feil, otras anormalias congenitas, hipertension arterial incontrolada y una estenosis unilateral de la arteria renal.

    Posterior reversible encephalopathy syndrome (PRES) is usually a reversible clinical and radiological entity associated with typical features on brain MR or CT imaging. However, the not-so-uncommon atypical radiological presentations of the condition are also present and they may go unrecognised as they are confused with other conditions. Here, we report a very rare case of atypical, unilateral PRES in a 49-year-old uremic, post-transplant female patient who presented with seizures. Initial MRI showed high-grade occlusion of the left middle cerebral artery (MCA) and lesions suggestive of subacute infarction in the ipsilateral frontotemporoparietal lobe. Patient symptoms had resolved a day after the onset without any specific treatment but early follow-up CT findings suggested hemorrhagic transformation. Follow-up MRI performed 2 years later showed complete disappearence of the lesions and persisting MCA occlusion.

  18. An Unusual Aneurysm of the Main Pulmonary Artery Presenting as Acute Coronary Syndrome

    International Nuclear Information System (INIS)

    A 70-year old man presented with retrosternal chest pain. His electrocardiogram showed nonspecific T wave changes. Cardiac-specific troponin I (cTnI) was elevated. His condition was managed as acute coronary syndrome, following which he had two minor episodes of hemoptysis. A CT pulmonary angiogram showed no evidence of pulmonary embolism, but a large mass lesion was seen in the mediastinum. Echocardiography and cardiac MRI demonstrated a large solid mass, arising from the right ventricular outflow tract and causing compression of the main pulmonary artery (MPA). The differential diagnosis included pericardial and myocardial tumors and clotted aneurysm of the MPA. At surgery, a clotted aneurysmal sac was identified originating from the MPA and the defect was healed. Aneurysms of the MPA are rare. They most commonly present with dyspnea and chest pain. Compression of surrounding structures produces protean manifestations. A high index of suspicion coupled with imaging modalities establishes the diagnosis. Blunt trauma to the chest, at the time of an accident 4 years previously, may explain this aneurysm. The patient's presentation with chest pain was probably due to compression and/or stretching of surrounding structures. Coronary artery compression simulating acute coronary syndrome has been documented in the literature. The rise in cTnI may have been due to right ventricular strain, as a result of right ventricular outflow obstruction by the aneurysm. This has not been reported previously in the literature. The saccular morphology and narrow neck of the aneurysm predisposed to stagnation leading to clotting of the lumen and healing of the tear, which caused the diagnostic difficulty

    2012-07-01

    Full Text Available Background: Endothelial dysfunction can influence fertility rate in women with polycystic ovary syndrome (PCOS as flow mediated dilatation (FMD is impaired in patients with the disease. The aim of this study was to compare two methods of ovulation induction by letrozole or letrozole plus human menopausal gonadotropins (HMGs in infertile women with PCOS who were resistant to clomiphene citrate based on brachial artery ultrasound findings.Methods: In this double -blind randomized clinical trial, 59 infertile women who had the inclusion criteria for PCOS were evaluated in the Infertility Clinic of Shariati Hospital in Tehran, Iran in 2010-2011. The patients were assigned to two letrozole and letrozole plus HMG groups and were evaluated for FMD in the brachial artery by transvaginal ultrasonography. Later, the values were recorded and analyzed statistically.Results: In the letrozole group, infertility treatment was successful in 15 (57.7% but it failed in 11 (42.3% patients. In letrozole plus HMG group, the treatment was successful in 18 (54.5% while it failed in 15 (45.5% patients. The mean FMD values in the groups with successful and unsuccessful treatment results were 19.42±10% and 18.57±7.2%, respectively, but the difference was not statistically significant (P=0.712. Moreover, the average endometrial thickness in groups with successful and unsuccessful treatment results were 8.4±1.3 mm and 9.8±3.9 mm, respectively but the difference was not significant either (P=0.06.Conclusion: In infertile women with polycystic ovary syndrome that are resistant to clomiphene, letrozole or letrozole combined with gonadotropin can be equally effective for ovulation induction.

    Full Text Available We report a case of multiple spontaneous arteries dissection in a 52-year-old female; the patient had a relevant family history of vascular complications and typical features so we hypothesized vascular Ehlers-Danlos syndrome (EDS that was confirmed by genetic analysis of COL3A1 gene. We adopted a conservative approach: the patient was treated with heparin in the acute phase followed by aspirin and then celiprolol was started on the basis of a recent trial that demonstrates a reduction in arterial events in EDS patient treated. A careful follow-up was done with Doppler ultrasound and computed tomography scan, as non-invasive diagnostic techniques are preferred in these patients, and no other vascular symptomatic events have occurred. We tested all living relatives: half of them had COL3A1 mutation, they were referred to another center specialized in rare diseases and EDS for long-term follow-up and genetic counseling. This case demonstrates as a careful evaluation of clinical signs, clinical history of the patient and his family has allowed a definitive diagnosis, proper management of the patient during the acute event and in terms of prophylaxis of recurrence.

  1. Garden sharing and garden stealing in fungus-growing ants

    Science.gov (United States)

    Adams, Rachelle M. M.; Mueller, U. G.; Holloway, Alisha K.; Green, Abigail M.; Narozniak, Joanie

    Fungi cultivated by fungus-growing ants (Attini: Formicidae) are passed on between generations by transfer from maternal to offspring nest (vertical transmission within ant species). However, recent phylogenetic analyses revealed that cultivars are occasionally also transferred between attine species. The reasons for such lateral cultivar transfers are unknown. To investigate whether garden loss may induce ants to obtain a replacement cultivar from a neighboring colony (lateral cultivar transfer), pairs of queenright colonies of two Cyphomyrmex species were set up in two conjoined chambers; the garden of one colony was then removed to simulate the total crop loss that occurs naturally when pathogens devastate gardens. Garden-deprived colonies regained cultivars through one of three mechanisms: joining of a neighboring colony and cooperation in a common garden; stealing of a neighbor's garden; or aggressive usurpation of a neighbor's garden. Because pathogens frequently devastate attine gardens under natural conditions, garden joining, stealing and usurpation emerge as critical behavioral adaptations to survive garden catastrophes.

    academic performance and health. AIMS: We aim to test the hypothesis that desires to steal among students would be associated with worse academic achievements and higher rates of mood and impulse control disorders. METHODS: One thousand eight hundred and five students completed the College Student Computer...... implications for practice and/or future research These following data indicate that stealing for many college students may be considered within a spectrum of impulsive behaviours. Illegal behaviours among students point to mental health difficulties among them. Our findings may provide clinicians, researchers...... and health professionals with a clearer picture of a range of impulsive behaviours among college students and promote treatment for this group. Our findings could also inform preventative approaches to impulsive problems in young adults. Copyright © 2015 John Wiley & Sons, Ltd....

  3. Left ventricular dysfunction during exercise in patients with angina pectoris and angiographically normal coronary arteries (syndrome X)

    International Nuclear Information System (INIS)

    Left ventricular function during exercise and recovery was investigated in patients with angina pectoris, ST segment depression during exercise and angiographically normal coronary arteries (syndrome X) using a continuous left ventricular function monitor with cadmium telluride detector (CdTe-VEST). Fourteen patients with syndrome X and 14 patients with atypical chest pain without ST segment depression during exercise and normal coronary arteries (control group) performed supine ergometric exercise after administration of 740-925 MBq of technetium-99m labelled red blood cells, and left ventricular function was monitored every 20 s using CdTe-VEST. Left ventricular ejection fraction (EF) response was impaired (≤ 5% increase from rest to peak exercise) in 11 or 14 patients with syndrome X but in none of the control patients. Resting EF was similar in the two groups (62.1% ± 6.7% in patients with syndrome X, 61.9% ± 6.2% in controls); however, EF increase from rest to peak exercise was lower in syndrome X (-3.1 ± 9.5% vs 14.7% ± 7.4%). After cessation of exercise, all patients showed rapid EF increase over baseline and this EF overshoot was lower (19.3% ± 8.3% vs 26.4% ± 7.3%) with the time to EF overshoot longer (114 ± 43 s vs 74 ± 43 s, P < 0.05) in patients with syndrome X.

    Full Text Available Abstract Background Type 2 diabetes and the metabolic syndrome are associated with impaired diastolic function and increased heart failure risk. Animal models and autopsy studies of diabetic patients implicate myocardial fibrosis, cardiomyocyte hypertrophy, altered myocardial microvascular structure and advanced glycation end-products (AGEs in the pathogenesis of diabetic cardiomyopathy. We investigated whether type 2 diabetes and the metabolic syndrome are associated with altered myocardial structure, microvasculature, and expression of AGEs and receptor for AGEs (RAGE in men with coronary artery disease. Methods We performed histological analysis of left ventricular biopsies from 13 control, 10 diabetic and 23 metabolic syndrome men undergoing coronary artery bypass graft surgery who did not have heart failure or atrial fibrillation, had not received loop diuretic therapy, and did not have evidence of previous myocardial infarction. Results All three patient groups had similar extent of coronary artery disease and clinical characteristics, apart from differences in metabolic parameters. Diabetic and metabolic syndrome patients had higher pulmonary capillary wedge pressure than controls, and diabetic patients had reduced mitral diastolic peak velocity of the septal mitral annulus (E', consistent with impaired diastolic function. Neither diabetic nor metabolic syndrome patients had increased myocardial interstitial fibrosis (picrosirius red, or increased immunostaining for collagen I and III, the AGE Nε-(carboxymethyllysine, or RAGE. Cardiomyocyte width, capillary length density, diffusion radius, and arteriolar dimensions did not differ between the three patient groups, whereas diabetic and metabolic syndrome patients had reduced perivascular fibrosis. Conclusions Impaired diastolic function of type 2 diabetic and metabolic syndrome patients was not dependent on increased myocardial fibrosis, cardiomyocyte hypertrophy, alteration of the

    Coronary artery ectasia (CAE) often represents a coronary angiography finding casually detected or following the occurrence of an acute coronary syndrome. The pathogenetic role of cocaine abuse in the genesis of CAE is still little known and very few data are available in literature. We describe a case of a 31-year-old male cocaine user admitted to our department for typical acute chest pain. Coronary angiography showed diffuse coronary ectasia with slow flows and without hemodynamically significant stenosis. An increasing of matrix metalloproteinases values and a reduction of their tissue inhibitors was showed both during hospitalization and at one month after discharge. This case report emphasizes the close relationship between cocaine abuse, CAE and acute coronary syndromes in patients without hemodynamically significant coronary stenosis. As reported by Satran et al, cocaine abuse should be considered an important risk factor for CAE and these patients appear to be at increased risk of angina and acute myocardial infarct. Further studies that can strengthen this hypothesis would be useful to deepen and better analyze this interesting association. PMID:27231522

    2013-06-01

    Full Text Available We report the case of a 24-year-old man presenting with sudden visual loss in the left eye from a central retinal artery occlusion. An extensive clinical investigation revealed no etiology. Three weeks later, however, the patient developed hearing loss followed by encephalopathy and multiple branch retinal artery occlusions in the right eye. Fluorescein angiography confirmed retinal vascular occlusions with no sign of vasculitis. The neurological examination revealed a diffuse encephalopathy while the MRI scan disclosed several small areas of infarcts in the brain. Bilateral sensorineural hearing loss was confirmed on audiometry. The patient was diagnosed with Susac syndrome and treated with methylprednisolone and cyclophosphamide, resulting in slight improvement and stabilization. This case shows that Susac syndrome may be diagnosed late due to the absence at onset of one or more of the symptoms of the classic triad (encephalopathy, multiple branch retinal artery occlusions and hearing loss. This case also serves to emphasize that Susac syndrome should be considered in the differential diagnosis of central retinal artery occlusion, even in apparently healthy young men.

    Full Text Available Stealing and passing credentials is currently one of the preferred cyberattack techniques within the hacking community as shown by the increasing number of related incidents over the last years. Instead of targeting passwords, attackers focus on obtaining derived credentials like hashes and session tickets. This type of credentials facilitates taking advantage of omnipresent background mechanisms like Single Sign-On. A combination of malware and penetration tools is used in order to exploit architecture vulnerabilities and steal the credentials. Vulnerabilities also allow the attacker to get access to other systems and covertly take the control of central infrastructure like Active Directory. The ultimate goal is not creating damage that can be noticed but covertly and constantly leaking confidential information for profit or cyber spionage.This paper proposes a comprehensive strategy of six points against steal-and-pass credential attacks and is intended to mitigate the risk significantly. Even if some points of the strategy can be considered security best-practices, other points require the establishment of technical and process controls that are not part of typical security management programs. Controls have to be regularly reviewed as part of security audits, since administrators and other privileged users have often the means to remove or bypass technical controls

    Superior mesenteric artery syndrome (SMAS) is defined as an obstruction of the third part of duodenum due to compression by the superior mesenteric artery. Although traumatic brain injury is a risk factor for SMAS, few cases of SMAS resulting from brain surgery have been reported. SMAS has been observed to occur following neurosurgical surgery in pediatric patients but, to the best of our knowledge, no such cases have been reported in adults. The present study reports the case of a 21-year-ol...

    Unlike vascular Ehlers-Danlos syndrome (EDS), classic EDS is rarely associated with vascular manifestation. We report the case of a 39-year-old man who presented with acute abdominal pain. At the time of presentation, the patient was in hypovolemic shock, and computed tomography angiogram demonstrated common iliac artery dissection with rupture. He underwent an attempted endovascular repair that was converted to an open repair of a ruptured right common iliac artery dissection. Subsequent genetic testing revealed a substitution of arginine for cysteine in type I collagen, COL1A1 exon 14 c.934C>T mutation, consistent with a rare variant of classic EDS. PMID:25597651

  13. Optimizing Data Locality for Fork/Join Programs Using Constrained Work Stealing

    Energy Technology Data Exchange (ETDEWEB)

    Lifflander, Jonathan; Krishnamoorthy, Sriram; Kale, Laxmikant

    2014-11-16

    We present an approach to improving data locality across different phases of fork/join programs scheduled using work stealing. The approach consists of: (1) user-specified and automated approaches to constructing a steal tree, the schedule of steal operations and (2) constrained work stealing algorithms that constrain the actions of the scheduler to mirror a given steal tree. These are combined to construct work stealing schedules that maximize data locality across computation phases while ensuring load balance within each phase. These algorithms are also used to demonstrate dynamic coarsening, an optimization to improve spatial locality and sequential overheads by combining many finer-grained tasks into coarser tasks while ensuring sufficient concurrency for locality-optimized load balance. Implementation and evaluation in Cilk demonstrate performance improvements of up to 2.5x on 80 cores. We also demonstrate that dynamic coarsening can combine the performance benefits of coarse task specification with the adaptability of finer tasks.

  14. Evaluation by multislice computed tomography of atherosclerotic coronary artery plaques in non-culprit, remote coronary arteries of patients with acute coronary syndrome

    International Nuclear Information System (INIS)

    Patients with acute coronary syndrome (ACS) frequently have vulnerable plaques in the remote coronary arteries, suggesting that ACS is part of the pan-coronary process. In the present study the computed tomography (CT) plaque density in non-culprit atherosclerotic coronary artery lesions was evaluated by multi-slice computed tomography (MSCT) in patients with ACS and non-ACS. MSCT was performed in 21 patients with ACS and 53 patients with non-ACS: 16 of the 21 ACS patients (76%) and 30 of the non-ACS 53 patients (57%) had non-calcified plaques in the non-culprit coronary arteries (p=0.18). CT-low-density plaques (CT density <68 Hounsfield units (HU)) were more frequent in the ACS group (13/16 patients, 81%) than in the non-ACS group (13/30 patients, 43%, p=0.03). In addition, the CT density of the non-culprit lesion was significantly lower in patients with ACS than in those with non-ACS (44.1±22.9 and 77.3±33.7 HU, respectively). Patients with ACS more frequently had CT-low-density plaques in the non-culprit, remote arteries than those with non-ACS, which suggests that ACS treatment should focus not only on stabilizing the culprit lesion but also on systemic stabilization of non-culprit lesions.

    Background People with metabolic syndrome are at higher risk for developing coronary artery disease (CAD).The effect of the metabolic syndrome on outcomes in patients with preexisting CAD has not been well studied.This study was conducted to assess the prevalence, characteristics, in hospital and long term prognosis of CAD with metabolic syndrome and to determine the factors influencing the prognosis of the disease.Methods The DESIRE registry contains data of 3696 patients with CAD between 2001 and 2004. Mean long term followup was (829±373) days. Diagnosis of metabolic syndrome was based on modified International Diabetes Federation (IDF) Worldwide Definition of the Metabolic Syndrome, using body mass index (BMI)instead of waist circumference.Results Of 2596 patients with complete records of height, weight, and so on, 1280 (49.3%) were identified with metabolic syndrome. The patients with metabolic syndrome had higher level of body mass index, systolic blood pressure, diastolic blood pressure, fasting glucose and disordered blood lipid (all P<0.0001), with higher creatinine [(10.5±4.3) mg/L vs (9.9±2.9) mg/L, P<0.0001] and the number of white blood cells [(7.49±2.86)× 109/L vs (7.19 ± 2.62) × 109/L, P=0.008) compared with those without metabolic syndrome. The patients with metabolic syndrome showed severer coronary angiographic alterations (left main artery and/or ≥2-vessel)(73.6% vs 69.6%, P=0.031). There were no significant differences of major adverse cardiac and cerebral events(MACCE) or mortality in hospital between the two groups. During followup, the ratio of MACCE in CAD with metabolic syndrome patients increased significantly (11.8% vs 10.0%, P=0.044). Fasting blood glucose (≥ 1000mg/L) and triglyceride (TG, ≥ 1500 mg/L) were responsible for most of the increased risk associated with the metabolic syndrome (adjusted OR 1.465, 95% CI 1.037-1.874, P=0.032; OR 1.378, 95% CI 1.014-1.768,P=0.044).Conclusions The prevalence of metabolic

    Pulmonary vascular remodelling, mainly characterized by arterial medial thickening, is an important pathological feature of broiler ascites syndrome (AS). Since vascular smooth muscle cells (VSMC) form the major cellular component of arterial medial layer, we speculate that VSMC proliferation is one of the causes of pulmonary arterial medial thickening in ascitic broilers. Hence, the present study was designed to investigate the role of VSMC proliferation in pulmonary vascular remodelling in development of AS induced by low ambient temperature. Broilers in control group (22 +/- 1.5 degrees C) and low temperature group (11 +/- 2 degrees C) were sampled every week at 15-50 days of age. Proliferative indexes of VSMC in pulmonary arteries were assessed with proliferating cell nuclear antigen, and the relative medial thickness (RMT) and relative wall area (RWA), as indexes of pulmonary vascular remodelling, were examined by computer-image analysing system. The results showed that the high incidence (18.75%) of AS was induced by low temperature, and a significantly increased VSMC proliferation was observed in pulmonary arteries in the low temperature group at 22-50 days of age (P < 0.05). In addition, RMT and RWA in pulmonary arteries were significantly elevated in the low temperature group from 36 days of age (P < 0.05), indicating that pulmonary vascular remodelling occurred following VSMC proliferation in AS. Our data suggest that proliferation of VSMC may facilitate pulmonary vascular remodelling and have a pivotal role in AS induced by low ambient temperature. PMID:18045340

    AIM: To investigate the risk indicators, pattern of clinical presentation and treatment strategy of superior mesenteric artery syndrome (SMAS) after scoliosis surgery.METHODS: From July 1997 to October 2003, 640 patients with adolescent scoliosis who had undergone surgical treatment were evaluated prospectively, and among them seven patients suffered from SMAS after operation. Each patient was assigned a percentile for weight and a percentile for height. Values of the 5th、 10th、 25th、 50th、 75th、 and 95thpercentiles were selected to divide the observations. The sagittal Cobb angle was used to quantify thoracic or thoracolumbar kyphosis. All the seven patients presented with nausea and intermittent vomiting about 5 d after operation.An upper gastrointestinal barium contrast study showed a straight-line cutoff at the third portion of the duodenum representing extrinsic compression by the superior mesenteric artery (SMA).RESULTS: The value of height in the seven patients with SMAS was above the mean of sex- and age-matchednormal population, and the height percentile ranged from 5% to 50%. On the contrary, the value of weight was below the mean of normal population with the weight percentile ranging from 5% to 25%. Among the seven patients, four had a thoracic hyperkyphosis ranging from 55° to 88°(average 72°), two had a thoracolumbar kyphosis of 25° and 32° respectively. The seven patients were treated with fasting, antiemetic medication, and intravenous fluids infusion. Reduction or suspense of traction was adopted in three patients with SMAS during halo-femoral traction after anterior release of scoliosis. All the patients recovered completely with no sequelae. No one required operative intervention with a laparotomy.CONCLUSION: Height percentile<50% , weight percentile <25%, sagittal kyphosis, heavy and quick halo-femoral traction after spinal anterior release are the potential risk indicators for SMAS in patients undergoing correction surgery

    Marfan syndrome (MFS) is a connective tissue disorder that is often associated with the fibrillin-1 (Fbn1) gene mutation and characterized by cardiovascular alterations, predominantly ascending aortic aneurysms. Although neurovascular complications are uncommon in MFS, the improvement in Marfan patients' life expectancy is revealing other secondary alterations, potentially including neurovascular disorders. However, little is known about small-vessel pathophysiology in MFS. MFS is associated with hyperactivated transforming growth factor (TGF)-β signaling, which among numerous other downstream effectors, induces the NADPH oxidase 4 (Nox4) isoform of NADPH oxidase, a strong enzymatic source of H2O2 We hypothesized that MFS induces middle cerebral artery (MCA) alterations and that Nox4 contributes to them. MCA properties from 3-, 6-, or 9-mo-old Marfan (Fbn1(C1039G/+)) mice were compared with those from age/sex-matched wild-type littermates. At 6 mo, Marfan compared with wild-type mice developed higher MCA wall/lumen (wild-type: 0.081 ± 0.004; Marfan: 0.093 ± 0.002; 60 mmHg; P Marfan mice with Nox4 deficiency (Nox4(-/-)). Strikingly, Nox4 deletion in Marfan mice aggravated MCA wall thickening (cross-sectional area; Marfan: 6,660 ± 363 μm(2); Marfan Nox4(-/-): 8,795 ± 824 μm(2); 60 mmHg; P < 0.05), accompanied by decreased TGF-β expression and increased collagen deposition and Nox1 expression. These findings provide the first evidence that Nox4 mitigates cerebral artery structural changes in a murine model of MFS. PMID:26945079

    Lindow, Thomas; Pahlm, Olle; Nikus, Kjell

    2016-01-01

    In acute coronary syndromes without ST-segment elevation (NSTE-ACS), identification of the culprit artery is, most often, not possible. In this case report, we elaborate on the likelihood of different culprit arteries in a patient with NSTE-ACS. While her symptoms were progressing, typical ECG findings of ischemia in the left coronary territories were diminishing. Instead, dynamic T-wave changes in the inferior leads were present and were most likely postischemic and "reischemic." Although the culprit artery could not be identified with certainty by means of these subtle changes, they correlated well with the findings on angiography and the ECG recorded afterward. This case report demonstrates the importance of analyzing ECG and its temporal changes in conjunction with evolving symptoms. PMID:27212142

  4. Internal carotid artery dissection in a patient with Ehlers-Danlos syndrome type IV: diagnosis and management

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Ehlers-Danlos syndrome (EDS type IV, also known as vascular EDS, is an inherited connective tissue disorder with an estimated prevalence of 1/100,000 to 1/250,000. In EDS type IV, vascular complications may affect all anatomical areas, with a preference for large- and medium-sized arteries. Dissections of the vertebral and carotid arteries in their extra- and intra-cranial segments are typical. The authors report the case of a patient with EDS type IV for whom the diagnosis was established based on clinical signs and who developed internal carotid artery dissection at the age of 44 years. In the absence of a specific treatment for EDS type IV, medical interventions should focus on symptomatic relief, prophylactic measures, and genetic counseling. Invasive imaging techniques are contraindicated, and a conservative approach to vascular complications is usually recommended.

    UNLABELLED: This study investigated the effect of the metabolic syndrome associated risk factors hyperglycemia (glucose [Glc]), hyperinsulinemia (insulin [Ins]) and low-grade inflammation (tumor necrosis factor α [TNFα]) on the vasomotor responses of resistance arteries. Isolated small mesenteric...... arteries from 3-month-old Sprague-Dawley rats, were suspended for 21-23 h in tissue cultures containing either elevated Glc (30 mmol/l), Ins (100 nmol/l), TNFα (100 ng/ml) or combinations thereof. After incubation, the vascular response to noradrenaline (NA), phenylephrine, isoprenaline and NA in the...... presence of propranolol (10 µmol/l) was measured by wire myography. RESULTS: Arteries exposed only to combinations of the risk factors showed a significant 1.6-fold increase in the contractile NA sensitivity, which suggests that complex combinations of metabolic risk factors might lead to changes in...

    The purpose of this study was to describe covered-stent treatment of a ruptured dissection of the superior mesenteric artery (SMA) in a patient with Ehlers‒Danlos syndrome. The patient was a 13-year-old girl initially presenting with abdominal pain. Dissection and rupture of the SMA were diagnosed on detailed examination. Conservative treatment was performed initially because open surgery was considered high risk. However, the abdominal pain recurred, and we decided to perform endovascular therapy. A coronary artery covered stent was placed in the true lumen to close the entry site of the dissection. The false lumen was obliterated using a post-dilation technique, completing treatment of the rupture. The patient recovered uneventfully after surgery. Classic-type Ehlers‒Danlos syndrome was diagnosed on the basis of physical findings and genetic analysis. The stent has remained adequately patent as of 2 years after surgery. This case report shows that dissection and rupture of the SMA can be treated successfully using a covered coronary artery stent in a patient with Ehlers‒Danlos syndrome. PMID:23891251

  7. Positive association between increased popliteal artery vessel wall thickness and generalized osteoarthritis: is OA also part of the metabolic syndrome?

    International Nuclear Information System (INIS)

    The purpose of the study was to determine if a positive association exists between arterial vessel wall thickness and generalized osteoarthritis (OA). Our hypothesis is that generalized OA is another facet of the metabolic syndrome. The medical ethical review board of our institution approved the study. Written informed consent was obtained from each patient prior to the study. Magnetic resonance (MR) images of the knee were obtained in 42 patients who had been diagnosed with generalized OA at multiple joint sites. Another 27 MR images of the knee were obtained from a matched normal (non-OA) reference population. Vessel wall thickness of the popliteal artery was quantitatively measured by dedicated software. Linear regression models were used to investigate the association between vessel wall thickness and generalized OA. Adjustments were made for age, sex, and body mass index (BMI). Confidence intervals (CI) were computed at the 95% level and a significance level of α = 0.05 was used. Patients in the generalized OA population had a significant higher average vessel wall thickness than persons from the normal reference population (p ≤ α), even when correction was made for sex, age, and BMI. The average vessel wall thickness of the popliteal artery was 1.09 mm in patients with generalized OA, and 0.96 mm in the matched normal reference population. The association found between increased popliteal artery vessel wall thickness and generalized osteoarthritis suggests that generalized OA might be another facet of the metabolic syndrome. (orig.)

    Full Text Available Background: Inflammation plays a major role in the development and progression of atherosclerosis and coronary artery disease (CAD. Inflammation markers, including white blood cell (WBC count, C-reactive protein (CRP and interleukin-6 (IL-6, are widely used for cardiovascular risk prediction. The aim of the study was to establish factors associated with WBC, CRP and IL-6 in patients with CAD. Two functional polymorphisms in genes encoding enzymes participating in adenosine metabolism were analyzed (C34T AMPD1, G22A ADA. Methods: Plasma concentrations of IL-6 were measured using high-sensitivity ELISA kits, and the nephelometric method was used for high-sensitivity CRP (hs-CRP measurement in 167 CAD patients. Results: Presence of metabolic syndrome (MS and its components, presence of heart failure, severity of CAD symptoms, severe past ventricular arrhythmia (sustained ventricular tachycardia [sVT] or ventricular fibrillation [VF], lower left ventricle ejection fraction, higher left ventricle mass index, higher end-diastolic volume and higher number of smoking pack-years were significantly associated with higher WBC, CRP and IL-6. Strong associations with arrhythmia were observed for IL-6 (median 3.90 vs 1.89 pg/mL, p<0.00001 and CRP concentration (6.32 vs 1.47 mg/L, p=0.00009, while MS was associated most strongly with IL-6. CRP and IL-6 were independent markers discriminating patients with sVT or VF. There were no associations between AMPD1 or ADA genotypes and inflammation markers. Conclusions: WBC, CRP and IL-6 are strongly associated with components of the metabolic syndrome. Their strong association with life-threatening ventricular arrhythmia emphasizes the proarrhythmic role of inflammation in the increased cardiovascular risk of CAD patients.

    1. Objective Combine collective clinical experience using oral propranolol therapy in PHACE syndrome infants with cerebrovascular anomalies. 2. Design Retrospective study of patients evaluated between July 2008 and October 2011. 3. Setting Seven pediatric dermatology centers. 4. Patients 32 infants with definite PHACE syndrome and cervical and/or intracranial arterial anomalies. 5. Intervention Oral propranolol: average dose of 1.8 mg/kg/day divided t.i.d. or b.i.d., for an average duration of 12.3 months. 6. Main Outcome Measure Adverse neurologic events. 7. Results 7/32 (22%) patients were categorized as higher-risk for stroke, defined on MRA as severe, long-segment narrowing or non-visualization of major cerebral or cervical vessels without anatomic evidence for collateral circulation, often in the presence of concomitant cardiovascular comorbidities. Only 1 patient developed a change in neurologic status during propranolol treatment: a mild right hemiparesis that remained static and improved while propranolol was continued. An additional 3 patients had worsening hemangioma ulceration and/or tissue necrosis during therapy. 8. Conclusions This is the largest report thus far of PHACE patients treated with propranolol. While no catastrophic neurologic events occurred, serious complications, particularly severe ulcerations were seen in a minority of patients, and given the sample size we cannot negate the possibility that propranolol could augment the risk of stroke in this population. We continue to advise caution in using systemic beta-blockers, particularly for children with vascular anomalies at higher risk for stroke. Use of the lowest possible dosage, slow dosage titration, and t.i.d. dosing in order to minimize abrupt changes in blood pressure and close follow-up, including neurologic consultation as needed, are recommended.

    Streptococcal toxic shock syndrome (STSS), an invasive Streptococcus pyogenes (Group A streptococcus) infection with hypotension and multiple organ failure, is quite rare in pregnancy but is characterized by rapid disease progression and high fatality rates. We present a case of STSS with infection-induced cardiac dysfunction in a pregnant woman who was treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO). A 24-year-old multiparous woman in the third trimester had early symptoms of high fever and diarrhea 1 day prior to admission to the hospital emergency department. On admission, she had multiple organ failure including circulatory failure. Due to fetal distress, emergency Cesarean section was carried out and transferred to intensive care units. She had refractory circulatory failure with depressed myocardial contractility with progressive multiple organ failure, despite receiving significant hemodynamic supports including high-dose catecholamine. Thus, VA-ECMO was initiated 18 h after intensive care unit admission. Consequently, ECMO provided extra time to recover from infection and myocardial depression. She was successfully weaned from VA-ECMO on day 7 and was discharged home on day 53. VA-ECMO can be a therapeutic option for refractory circulatory failure with significant myocardial depression in STSS. PMID:26758056

    Anterior spinal artery syndrome (ASAS) often leads to complete motor paralysis with poor clinical outcome. There is a lack of controlled clinical trials on acute treatment strategies in ASAS. However, systemic thrombolysis with recombinant tissue-plasminogen activator (rt-PA) might be a useful therapeutic option in ASAS. We report the management of a patient with ASAS below thoracic level 10, who was treated with intravenous thrombolysis. An 81 year old patient presented with flaccid paraplegia. After exclusion of aortal dissection, spinal tumour or haemorrhage, the patient was treated with intravenous rt-PA 3 h 40 min after symptom onset. The follow up magnetic resonance imaging (MRI) showed spinal infarction below thoracic segment 10. In the clinical course, the patient partially recovered lower limb muscle strength and was able to walk with assistance. To the best of our knowledge, this is the first case in the literature of ASAS with MRI-proven spinal ischemia and the application of rt-PA. Systemic thrombolysis seems to be justifiable in patients with ASAS after the rule-out of aortal dissection and spinal bleeding. PMID:26386968

    AIM: To assess the clinical value of duodenal circular drainage for superior mesenteric artery syndrome (SMAS).METHODS: Forty-seven cases of SMAS were treated with duodenal circular drainage from 1959 to 2001.Clinical data were analyzed retrospectively.RESULTS: In this group, good effects were achieved in 39 cases treated with duodenal circular drainage after 2-15 years of follow-up. The other eight cases were first treated with anterior repositioning of the duodenum (two cases), duodenojejunostomy (five cases), subtotal gastrectomy and billroth 11 gastrojejunostomy (one case), but vomiting was not relieved until duodenal circular drainage was performed again. A follow-up study of 8-10 years revealed satisfactory results in these eight patients.CONCLUSION: In SMAS, if the reversed peristalsis is strong and continuous, and vomiting occurs frequently,the symptom can not be relieved even if the obstruction of duodenum is removed surgically. The key treatment is the relief of reversed peristalsis. The duodenal circular drainage can resolve the drainage direction of duodenal content, thus relieving the symptom of vomiting.

  14. Evaluation of coronary artery remodeling in patients with acute coronary syndrome and stable angina by multislice computed tomography

    International Nuclear Information System (INIS)

    Multislice computed tomography (MSCT) was used to evaluate coronary artery remodeling in patients with acute coronary syndrome (ACS) and stable angina (SA). MSCT was performed in 31 patients with ACS and 26 patients with SA and intravascular ultrasound (IVUS) was performed in 28 of these 57 patients. In both the MSCT and IVUS analyses, coronary artery remodeling was assessed by the remodeling index (RI): RI>1.10 was defined as positive coronary artery remodeling (PCAR) and RI<0.95 was defined as negative coronary artery remodeling (NCAR). The RI assessed by MSCT closely correlated with that of IVUS (r=0.86, n=28). The vessel area at the region of maximum luminal narrowing was also comparable between the MSCT and IVUS measurements (r=0.92). PCAR was present in 19 patients (61.3%) with ACS, but in none of the patients with SA (p<0.0001). However, NCAR was present in only 1 patient with ACS (3.2%), but was present in 18 patients (62.9%) with SA. The RI was significantly larger in patients with ACS (1.19±0.18) than in those with SA (0.89±0.10, p<0.0001). MSCT accurately assesses coronary artery remodeling. (author)

    Full Text Available Acute Respiratory Distress Syndrome (ARDS is a potential complication of cardiac surgery, given that patients undergoing CABG frequently have hypoxemia and pulmonary dysfunction during initial hours after surgery. Thus, ARDS criteria in these patients are more likely to be positive while these criteria may not match the patient`s clinical picture. We aimed to investigate frequency of rapid onset hypoxemia in Pressure of Arterial Oxygen to Fractional Inspired Oxygen Concentration (PaO2/FiO2 less than 200 and diffuse pulmonary infiltrates as two diagnostic criteria forwards and compared these criteria with the clinical picture of the patients after Coronary Artery Bypass Graft (CABG in this study. The study was prospective case series which carried out in about six months. All patients admitted to intensive care unit of Tehran Heart Center, who had undergone CABG on cardiopulmonary pump (CPB recruited in the study. After considering inclusion criteria, age, sex, duration of intubation, arterial blood gas and chest radiography, on 24 hours and 48 hours after admission to the ICU were recorded. Then, patients with rapid onset of hypoxemia (PaO2/FiO2≤200mmHg and diffuse pulmonary infiltrates and without sign or symptoms of obvious heart failure (probable positive ARDS cases criteria were recorded and comparison between these probable positive cases with clinician`s clinical diagnosis (blinded to the study was performed. In this study, a total of 300 patients after on-pump coronary artery bypass surgery were included. Postoperatively, 2 (0.66 % in the 24 hours and 4 (1.33% patients in 48 hours after surgery were positive for the two ARDS criteria according to the checklists, but; nobody had saved persistently ARDS criteria persistently during 48 hours after surgery. At the same time, clinician did not report any case of ARDS among 300 patients. In this study patients with ARDS criteria had no significant differences in age (P.value=0.937 and sex (P

    Full Text Available Background: Left main coronary artery (LMCA stenosis is a leading cause of mortality and morbidity in many countries. Metabolic syndrome (MS is a risk factor for coronary artery disease (CAD. The effects of MS on left main coronary artery stenosis are not well-defined. The aim of this study was to examine the effects of MS on left main coronary artery stenosis.Methods: A total number of 495 patients who underwent elective coronary angiography in the Catheter Laboratory of Cardiovascular in Shariati Hospital 2008-2010 were included in the study. MS definition was based on the National Cholesterol Education Program (NCEP- Adult Treatment Panel III (ATP III criteria. The stenosis in left main coronary arteries was determined by examining the coronary angiograms of the patients.Results: The study population consisted of 249 (50.3% men, and 246 (49.7% women. The mean age of the participants was 58.01±10 years. MS was present in 86 (17.4% of the patients based on NCEP- ATP III criteria. LMCA stenosis was seen in 25 (5% patients. A positive correlation was found between MS and LMCA stenosis (r=0.305, P=0.012. Moreover, a positive correlation was found between age (r=0.192, P=0.05, sex (r=0.334, P=0.007, smoking (r=0.336, P=0.01 and diabetes (r=0.253, P=0.03 and LMCA stenosis.Conclusion: The metabolic syndrome correlates with LMCA stenosis. LMCA stenosis and its correlation with MS is precipitated by high FBG, age, male sex, and smoking which may synergistically increase the risk for the disease.

    Antiplatelet therapy is used widely with proven benefit for the prevention of further ischemic cardiac complications in patients with known coronary artery disease (CAD) and a history of acute coronary syndrome (ACS). The limitations of conventional antiplatelet therapy with aspirin, clopidogrel, or prasugrel, as well as the fact that rates of recurrent ischemic events still remain high with use of these agents, underscore the need to investigate alternate agents that may further reduce event rates while limiting bleeding risk. The selection of antiplatelet therapy is further influenced by the following: ticagrelor was approved in July 2011 by the United States Food and Drug Administration (FDA), and clopidogrel is slated to become available as a generic productin 2012. We provide an overview of emerging agents for the treatment of CAD and ACS, including the reversible P2Y(12) antagonists ticagrelor, cangrelor, and elinogrel, and a new class of oral protease-activated receptor-1 (PAR-1) inhibitors, vorapaxar and atopaxar.The recently approved P2Y(12) antagonists prasugrel and ticagrelor demonstrate enhanced ability to prevent adverse cardiac outcomes. However, this comes at a cost of a potential increased risk of bleeding. New adverse effects have also emerged, including dyspnea for all of the reversible P2Y(12) antagonists (ticagrelor, cangrelor, and elinogrel) and ventricular pauses for ticagrelor. In addition, the newer P2Y(12) antagonists have a faster onset and offset. Two of these agents, cangrelor and elinogrel, are available as intravenous formulations, which may provide additional benefits in patients who undergo coronary artery bypass graft (CABG) surgery. Trials with the PAR-1 inhibitors have also shown trends toward reductions in cardiac events, but not without the possibility of increased bleeding. More than ever, as the arsenal of antiplatelet therapy expands, health care providers need to understand the pharmacologic and pharmacodynamic differences

    Cerebral hyperperfusion syndrome (HPS) is an uncommon but serious complication of carotid artery stenting (CAS). The purpose of this study was to investigate the efficacy of CT perfusion imaging (CTP) with acetazolamide challenge to identify patients at risk for HPS after CAS. We retrospectively analyzed 113 patients who underwent CTP with rest and acetazolamide challenge before CAS. CTP maps were assessed for absolute and relative cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), and change of each parameter before and after acetazolamide challenge. Patients were divided into two groups according to the HPS after the CAS. Receiver-operating characteristic (ROC) curve analysis was performed to determine the most accurate CTP parameter for the prediction of HPS. Nine of 113 patients had HPS. There were significant differences for absolute and relative values of resting CBF (p = 0.001 and p = 0.026), resting MTT (p < 0.001 and p = 0.004), post-acetazolamide CBF (p < 0.001 and p = 0.001), post-acetazolamide MTT (p < 0.001 and p = 0.002), and %changes of CBF (p = 0.009) between the HPS and non-HPS groups. ROC curve analysis showed that the CTP parameters with the maximal area under the receiver-operating characteristic curve (AUC) for HPS was the absolute value of post-acetazolamide MTT (AUC 0.909) and the absolute value of resting MTT (AUC 0.896). Pretreatment CTP with acetazolamide challenge could identify patients at risk for HPS after CAS. Although the CTP parameter that most accurately identified patients at risk for HPS was the absolute value of post-acetazolamide MTT, resting MTT was sufficiently accurate. (orig.)

    Full Text Available It is postulated that patients with ischaemic heart disease (IHD and coronary steal prone anatomy (CSPA may develop myocardial ischaemia under isoflurane anaesthesia. This study was conducted in 50 patients undergoing coronary artery bypass grafting. Among these 10 patients (20% had CSPA, as evidenced by coronary angiography. Anaesthesia was induced with fentanyl, midazolam and thiopentone and maintained with isoflurane in oxygen after endotracheal intubation. Patients were continuously monitored with automated ST segment analysis of electrocardiogram (ECG and transoesophageal echocardiography (TEE. The end-tidal concentration of isoflurane was maintained at 1.2%, which is equal to one minimum alveolar concentration. Haemodynamic parameters were maintained within 20% of baseline values with either the use of phenylephrine or increasing the depth of anaesthesia by using midazolam and fentanyl. ST changes were measured after 80 ms of J-point in ECG and TEE monitored for occurrence of new regional wall motion abnormalities during the study period. ST changes more than +/-1.0 mm were considered as an indication of myocardial ischaemia. Out of 10 patients having CSPA, 50% developed significant ECG changes during isoflurane anaesthesia at an endtidal concentration of 1.2%. In patients not having CSPA new ischaemia was not observed. Our study indicates necessity of close monitoring of patients with IHD and CSPA during isoflurane anaesthesia to identify new ischaemia and institute appropriate measures.

    The most prevalent lesion of the vertebral artery is an atheromatous plaque located at its origin from the subclavian artery. A case of successful management of a symptomatic vertebral artery aneurysm due to Ehlers-Danlos syndrome is reported. The patient had asymptomatic posterior intracerebral artery dissection on the contralateral side. A common carotid artery to V-3 segment bypass using reversed saphenous vein graft was carried out. Avulsion of the V-2 segment occurred peroperatively and endovascular coil embolization of the vertebral artery aneurysm was performed. Endovascular equipment and training must be in the armamentarium of vascular surgeons as more complex cases are being treated, which demands new approaches for ultimate clinical success. This unique case outlines what might unexpectedly occur. Endovascular intervention as an adjuvant procedure provides a satisfactory outcome in what could have been a catastrophe.

    There has traditionally been less concern regarding coronary anomalies with left-sided congenital heart lesions such as hypoplastic left heart syndrome (HLHS)or Shone complex than with other lesions. However, coronary anomalies in this setting can profoundly affect surgical intervention, particularly when surgical repair involves the ascending aorta. We describe four patients with congenital left-sided heart lesions in which left coronary artery (LCA) anomalies substantially affected intervention and outcome. In the first two cases, the coronary anomalies were not identified prospectively and resulted in surgical injury directly to the coronary or to its surrounding region. In the latter two cases, successful identification of the coronary anomaly preoperatively allowed for modification of surgical technique and/or intervention. We conclude that detailed coronary artery assessment should be part of the routine echocardiographic evaluation of congenital left-sided heart lesions that require surgery. PMID:18445061

    Superior mesenteric artery syndrome (SMAS) is defined as an obstruction of the third part of duodenum due to compression by the superior mesenteric artery. Although traumatic brain injury is a risk factor for SMAS, few cases of SMAS resulting from brain surgery have been reported. SMAS has been observed to occur following neurosurgical surgery in pediatric patients but, to the best of our knowledge, no such cases have been reported in adults. The present study reports the case of a 21-year-old female patient who developed SMAS after persistent vomiting and prolonged weight loss following cerebellar tumor resection and cranial irradiation. The SMAS was confirmed by computed tomography and resolved following successful nutritional management. PMID:26622529

The left cerebral vessels are supplied via the anterior communicating artery and the left persistent trigeminal artery. The coexisting coarctation of the aorta led to a subclavian steal phenomenon. The alteration of the cerebral hemodynamics has to be taken in consideration when performing cerebral angiography and surgical correction in such a case. (orig.)

    2011-01-01

    This paper analyzes the cache miss cost of algorithms when scheduled using randomized work stealing (RWS) in a parallel environment, taking into account the effects of false sharing. First, prior analyses (due to Acar et al.) are extended to incorporate false sharing. However, to control the possible delays due to false sharing, some restrictions on the algorithms seem necessary. Accordingly, the class of Hierarchical Tree algorithms is introduced and their performance analyzed. In addition, the paper analyzes the performance of a subclass of the Hierarchical Tree Algorithms, called HBP algorithms, when scheduled using RWS; improved complexity bounds are obtained for this subclass. This class was introduced in a companion paper with efficient resource oblivious computation in mind. Finally, we note that in a scenario in which there is no false sharing the results in this paper match prior bounds for cache misses but with reduced assumptions, and in particular with no need for a bounding concave function for t...

    Full Text Available In stage V twin–twin transfusion syndrome (TTTS, up to 50% of surviving twins die or experience permanent disabilities, likely due to acute intertwin hemorrhage resulting in sudden severe anemia of the survivor. Although fetal middle cerebral artery (MCA Doppler studies demonstrate strong correlation with fetal hemoglobin values, acute hemorrhagic events are more difficult to diagnose, and optimal timing of delivery of the survivor poses an obstetric dilemma. We report a case of newly diagnosed stage V TTTS at 28 weeks gestation, complicated by acute severe anemia diagnosed by significantly abnormal fetal MCA Doppler studies. The anemic twin was urgently delivered and is doing well without significant sequelae.

  10. Is celiac artery compression syndrome genetically inherited?: A case series from a family and review of the literature

    International Nuclear Information System (INIS)

    The median arcuate ligament is a tendinous arch joining the two medial borders of the diaphragm crura together. In 13–50% of asymptomatic subjects it is responsible for significant angiographic celiac trunk compression. The significance of median arcuate ligament-associated celiac artery compression has been a source of some controversy in the past literature, and the etiology remains unclear. We report here a case series from a family that was diagnosed by the use of multidetector computed tomography. The observation of this syndrome in a family suggests that the responsible anatomic relationships are congenital and may be genetically inherited.

    2010-01-01

    Full Text Available Antiphospholipid antibody syndrome (APLAS characterises a clinical condition of arterial and venous thrombosis associated with phospholipids directed antibodies. APLAS occurs in 2% of the general population. However, one study demonstrated that 7.1% of hospitalised patients were tested positive for at least one of the three anticardiolipin antibody idiotype. Antiphospholipid antibodies often inhibit phospholipids dependent coagulation in vitro and interfere with laboratory testing of hemostasis. Therefore, the management of anticoagulation during cardiopulmonary bypass can be quite challenging in these patients. Here, we present a case of right atrial mass removal and pulmonary thrombectomy in a patient of APLAS.

    Background High uric acid (UA) levels and metabolic syndrome (MS) are risk factors for atherosclerotic diseases.Brachial-ankle pulse wave velocity (baPWV) is a valid and reproducible measurement by which to assess arterial stiffness and a surrogate marker of atherosclerosis.However,little is known about the relationship between them,especially in elderly Chinese with MS components who are at high risk for atherosclerotic diseases.Methods One thousand and twenty Chinese subjects (159 women) older than 60 years of age (mean age (70.6±5.7)years) with at least one MS component underwent routine laboratory tests,and baPWV measurements were analyzed.Results Participants were divided into four groups by MS components.The mean age did not significantly differ among the MS component groups.We found that not only the diagnostic factors (blood pressure,body mass index (BMI),lipids,glucose) of MS but also baPWV,UA,insulin,homeostasis model of assessment for insulin resistence index (HOMAIR) levels increased,and high density lipoprotein (HDL)-C decreased with an increased number of MS components (test for trend P<0.05).The association between UA and baPWV was observed after adjustment for gender,age,blood pressure,BMI,serum creatinine and high density lipoprotein,and insulin resistance (r=0.186,P<0.0001).There were increases in the odds ratios for the association between the number of components of MS,UA and baPWV,even after adjustment for traditional risk factors.However,after adjustment for insulin or HOMA-IR,there were no significant differences in the multivariate odds ratios among the number of MS components for UA.Conclusions The UA level is positively associated with baPWV and MS,but the association between UA and MS is dependent on insulin resistance.Furthermore,baPWV is independently associated with MS in our study population.

    The present study aims to compare neuropsychological performance of patients following anterior communicating artery aneurysm rupture (ACoA) with that of patients with alcoholic Korsakoff syndrome (AKS). Fifteen ACoA patients and ten age-and education-matched AKS patients were included in the study. All the patients were tested at least one year post onset of their illness at a stable condition. The WAIS and forward digit span scores of AKS were also matched to ACoA, and simple attention and general intelligence were well preserved both in ACoA and AKS. Frontal function as measured by the Wisconsin card sorting test (Keio version) (KWCST) was equivalently impaired in the two groups. Anterograde memory as measured by Wechsler memory scale subtests, serial seven word learning test, Rey auditory verbal learning test, and logical memorizing test (Luria's paired word-picture association), was more severely impaired in AKS than ACoA in contrast to the comparable attention, intelligence, and frontal function: (1) memory tasks with low correlations to KWCST (serial word learning tasks and paired verbal associates), reflecting primary simple serial memorizing, and (2) memory tasks with high correlations to KWCST (logical memory and logical memorizing), reflecting higher and complicated strategic mnemonic activities. However, the correlations between these anterograde memory subtests and KWCST were substantially equivalent in ACoA and AKS. This suggests that the differences in anterograde amnesia demonstrated in ACoA and AKS may be of quantitative, not of qualitative property. The extent of deficits in semantic encoding as measured by Wickens' release from proactive interference paradigm (PI release) was also milder in ACoA than AKS. Both AKS and ACoA failed to show PI release in contrast to normal PI release demonstrated in age-matched ten healthy subjects. PI release in ACoA, however, was in between AKS and healthy subjects. The results were interpreted in the light of a

    Turner's syndrome (TS) has been documented as the most common cause of aortic dissection in young women. However, little attention from vascular surgery has been paid to these patients. We report the first case of ruptured type B aortic dissection with aberrant right subclavian artery treated successfully with hybrid endovascular and open procedures in a patient with TS. Left carotid to subclavian artery bypass, thoracic endovascular aortic repair, and coil embolization of the aberrant right subclavian and left subclavian arteries were performed in an emergency setting. Literature on epidemiology, causes, and management options of acute aortic dissection in TS patients are reviewed and discussed. PMID:24011806

  17. Abnormal course of the vertebral artery at the craniovertebral junction in patients with Down syndrome visualized by three-dimensional CT angiography

    International Nuclear Information System (INIS)

    We determined the incidence of vertebral artery (VA) anomalies at the craniovertebral junction (CVJ) in patients with Down syndrome, and characterized the VA anomalies. The course of the VA in 46 consecutive patients who were due to undergo posterior arthrodesis surgery at the CVJ were evaluated by three-dimensional CT angiography (3DCTA). Included were five patients with Down syndrome who suffered from myelopathy due to atlantoaxial subluxation. All five patients with Down syndrome also had a simultaneous congenital skeletal anomaly, either os odontoideum or ossiculum terminale. Of the five patients with Down syndrome, three had VA anomalies at the CVJ, two had fenestration and one had a persistent first intersegmental artery. Of the other 41 patients without Down syndrome, five had VA anomalies at the CVJ. The incidence of VA anomalies at the CVJ was much higher in patients with Down syndrome than in those without Down syndrome. In planning surgery in patients with Down syndrome with symptomatic atlantoaxial subluxation and a congenital skeletal anomaly at the CVJ, we should consider the possible presence of VA anomalies. Preoperative 3DCTA allows us to precisely identify an anomalous VA and evaluate the possible risk of intraoperative VA injury in advance. (orig.)

    The purpose of this study was to investigate the feasibility of inducing ocular ischemic syndrome in spontaneously hypertensive rats. Hypertensive and normotensive Wistar-Kyoto rats had bilateral occlusion or sham surgery. They were divided into 4 groups: (1) hypertensive-ischemia, (2) hypertensive-sham, (3) normotensive-ischemia, and (4) normotensive-sham. Four months after the operation, the global changes of the eye and pupillary light reflex were assessed. Then each rat was perfused, and randomly one of the bulbuses oculi was prepared as retinal flat mounts for investigation of vascular changes. The opposite eyeball was prepared as a paraffin section for observation of the linear density of retinal ganglion cells and for thickness measurement. One hypertensive-ischemia rat had a cataract in one eye and another rat in the same group had bulbus oculi collapse in one eye. The light reflex disappeared in 13.33% of hypertensive-ischemia rats, and the rest of the hypertensive-ischemia rats and normotensive-ischemia rats had slow reflex. Compared with the respective controls, the peripheral retinal vascular network in hypertensive-ischemia and normotensive-ischemia rats was sparse; linear density of the retinal ganglion cells was significantly reduced; and the retinal thickness was reduced. Compared with normotensive-ischemia rats, the hypertensive-ischemia rats demonstrated more severe changes. After bilateral common carotic artery occlusion, the eyes of hypertensive rats developed various pathological changes similar to those of ocular ischemic syndrome. In conclusion, an animal model for ocular ischemic syndrome can be created by bilateral common carotid artery occlusion in spontaneously hypertensive rats.

  1. Clinical evaluation of 99Tcm-MIBI myocardial perfusion imaging for the detection of coronary artery disease in patients with metabolic syndrome

    International Nuclear Information System (INIS)

    Objective: Metabolic syndrome is a combination of medical disorders that consist of a collection of independent factors at risk of developing coronary artery disease. The purpose of this study was to evaluate the value of 99Tcm-methoxyisobutylisonitrile (MIBI) myocardial perfusion imaging for the diagnosis of coronary artery disease in patients with metabolic syndrome. Methods: A total of 251 patients [mean age (59 ± 10) years, 179 men, 72 women] were included in this study. All patients underwent exercise and rest 99Tcm-MIBI myocardial perfusion imaging and coronary angiography. Results: Of the 163 patients with significant coronary artery stenosis, 116 showed abnormal 99Tcm-MIBI myocardial perfusion imaging; and among the 88 patients with normal coronary angiography, 82 showed normal myocardial perfusion imaging. The sensitivity, specificity and accuracy of 99Tcm-MIBI myocardial perfusion imaging for coronary artery disease detection were 71% (116/163), 93% (82/88) and 79% (198/251), respectively. The positive and negative predictive values were 95% (116/122) and 64% (82/129), respectively. Conclusion: 99Tcm-MIBI myocardial perfusion imaging has important clinical value for detecting coronary artery disease in patients with metabolic syndrome. (authors)

    The anomalous origin of the left coronary artery from the pulmonary artery - known as Bland-White-Garland syndrome - is a rare congenital malformation that affects 1 in 300,000 live births. Most patients die in infancy without any surgical treatment. Some patients who survive past childhood often have varying symptoms such as myocardial ischemia, impaired left ventricular function, mitral regurgitation, and progressive heart failure, depending on the development collateral circulation. In the present report, we describe a procedure wherein the left coronary artery ostium was translocated through the transverse sinus of the pericardium in a 43-year-old mother with Bland-White-Garland syndrome and concomitant mitral regurgitation and report on the associated midterm results.

  6. Arterial Tortuosity Syndrome reveals function of dehydroascorbic acid in collagen and elastin synthesis: Implications for skin care.

    Science.gov (United States)

    Kitt, Douglas Q

    2016-02-01

    Some investigations in Arterial Tortuosity Syndrome (ATS) suggest that impaired intracellular transport of the oxidized form of vitamin C (dehydroascorbic acid, DHAA) is at the core of the pathogenesis. Lack of vitamin C for lysyl- and prolyl-hydroxylase activity may explain the defects in collagen and elastin formation found in ATS, and draws strong parallels between ATS and scurvy. Topically applied vitamin C has a well-established basis in the field of skin care, and part of its benefit is attributed to proper collagen formation in the skin. The ATS studies suggest that DHAA transport is necessary for normal skin collagen formation, and this has implications as to the forms of vitamin C best-suited for topical skin care. PMID:26826631

    Full Text Available Abstract Introduction Nausea and vomiting in an adolescent, though common presenting symptoms, often pose a diagnostic and therapeutic challenge to the physician. When the diagnosis involves both medical and psychiatric components, management can be complex, especially in the current healthcare system in the United States. To the best of our knowledge, there have been no previous publications detailing successful management of a patient with anorexia nervosa and superior mesenteric artery syndrome. Case presentation We report the case of a 16-year-old Caucasian girl who presented to our emergency department with nausea, abdominal pain, diminished appetite and vomiting. Her history and examination were notable for a 15 kg weight loss and diffuse abdominal tenderness. A barium swallow X-ray with small bowel follow-through and computed tomography scan demonstrated remarkable duodenal narrowing between the superior mesenteric artery and the aorta, consistent with superior mesenteric artery syndrome. Initial management focused on relieving the obstruction and supporting the nutritional needs of the patient. Further history confirmed a diagnosis of anorexia nervosa, requiring intensive psychiatric and medical management, and necessitating a multifaceted approach to patient care involving social work, multiple primary care physicians and subspecialists, insurance company representatives, and the patient's immediate family. Conclusion This case illustrates important points regarding the pathogenesis of superior mesenteric artery syndrome in the setting of anorexia, and it highlights the complexities that arise when managing an adolescent with both medical and psychiatric needs, as well as outlining a viable solution. While superior mesenteric artery syndrome is an uncommon cause of small bowel obstruction, the general pediatrician and child psychiatrist should be aware of this complication of anorexia nervosa.

    A 48-year-old woman with a history of diabetes was admitted for nausea and vomiting with body weight loss. A blood examination revealed high plasma glucose and thyroid hormone levels and metabolic acidosis. She was therefore diagnosed with both diabetic ketoacidosis (DKA) and hyperthyroidism. Nausea and vomiting continued intermittently despite the administration of saline and insulin. The patient was further diagnosed with superior mesenteric artery syndrome (SMAS) after abdominal computed tomography revealed that a horizontal portion of the duodenum was sandwiched between the aorta and the superior mesenteric artery. Clinicians should be vigilant for SMAS in patients with both DKA and hyperthyroidism who present body weight loss. PMID:27477411

    Full Text Available Background: The aim of this study was to estimate the relationship between arterial stiffness and components of metabolic syndrome (MetS in different age- and gender groups.Methods: A total of 12,900 Chinese adults aged 20-79 years were recruited and stratified on the basis of gender and age. All participants underwent the measurement of waist circumference, blood pressure (BP, brachial-ankle pulse wave velocity (baPWV; an indicator of arterial stiffness, and blood chemistry. Multiple linear regression analysis was performed to evaluate the relationship between baPWV and above variables, to determine the relative influence of each component of MetS on baPWV.Results: The prevalence of metabolic disorders except for low high-density lipoprotein cholesterol (HDL-C was much higher in men than in women. All participants with MetS or any component of MetS except for low HDL-C had higher baPWV. BP was positively correlated with baPWV in all groups, while HDL-C was not correlated with baPWV in any groups. In addition, fasting glucose was related to baPWV in middle-aged adults and the elderly. Waist circumference had a positive association with baPWV in middle-aged adults and young men, triglyceride levels showed a significant correlation with baPWV in middle-aged women and young men. Of the MetS components, elevated BP was the strongest predictor of baPWV.Conclusion: The prevalence of metabolic disorders and the association between baPWV and metabolic variables are dependent on age and gender. Different components of MetS exert distinct impacts on the baPWV in different age- and gender groups, with BP being the strongest predictor. It is suggested that age and gender should be taken into accounted in the management of MetS aiming to reduce subsequent complications.

    Different forms of Ehlers-Danlos syndrome (EDS) exist, with specific phenotypes and associated genes. Vascular EDS, caused by heterozygous mutations in the COL3A1 gene, is characterized by fragile vasculature with a high risk of catastrophic vascular events at a young age. Classic EDS, caused by heterozygous mutations in the COL5A1 or COL5A2 genes, is characterized by fragile, hyperextensible skin and joint laxity. To date, vessel rupture in four unrelated classic EDS patients with a confirmed COL5A1 mutation has been reported. We describe familial occurrence of a phenotype resembling vascular EDS in a mother and her two sons, who all died at an early age from arterial ruptures. Diagnostic Sanger sequencing in the proband failed to detect aberrations in COL3A1, COL1A1, COL1A2, TGFBR1, TGFBR2, SMAD3, and ACTA2. Next, the proband's DNA was analyzed using a next-generation sequencing approach targeting 554 genes linked to vascular disease (VASCULOME project). A novel heterozygous mutation in COL5A1 was detected, resulting in an essential glycine substitution at the C-terminal end of the triple helix domain (NM_000093.4:c.4610G>T; p.Gly1537Val). This mutation was also present in DNA isolated from autopsy material of the index's brother. No material was available from the mother, but the mutation was excluded in her parents, siblings and in the father of her sons, suggesting that the COL5A1 mutation occurred in the mother's genome de novo. In conclusion, we report familial occurrence of lethal arterial events caused by a COL5A1 mutation. PMID:25845371

    Full Text Available "nKawasaki disease (KD is an inflammatory multiorgan disease of unknown etiology. The most dramatic organ involved is the heart. There were a few studies about cardiac involvement and sterile pyuria. This study guides to determine if sterile pyuria is associated with coronary artery aneurysm (CAA in KD patients and to consider it as a predicting factor for coronary artery involvement. Forty seven patients with KD were studied by echocardiography in admission and one month later. Urine analysis, complete blood count, erythrocyte sedimentation rate and C-reactive protein were measured in admission. Data were analyzed using SPSS-14 software. Patients' age was ranged from 13 month to 7 years old (mean age of 3.43 ± 1.54 years. Thirty patients (63.8% were male and 17 patients (36.1% were female. Cardiac involvement was detected in 32 patients (68% using echocardiography, of which CAA was reported in 8 cases (17%. Six of CAA (75% were in association with sterile pyuria, although it was statistically insignificant (P>0.05. Although the majority of patients with CAA had sterile pyuria, this association is not statistically significant, thus it couldn't be considered as a predicting factor for CAA.

    Full Text Available Abstract A coronary arterial fistula is a connection between one or more of the coronary arteries and a cardiac chamber or great vessel. This is a rare defect and usually occurs in isolation. Its exact incidence is unknown. The majority of these fistulas are congenital in origin although they may occasionally be detected after cardiac surgery. They do not usually cause symptoms or complications in the first two decades, especially when small. After this age, the frequency of both symptoms and complications increases. Complications include 'steal' from the adjacent myocardium, thrombosis and embolism, cardiac failure, atrial fibrillation, rupture, endocarditis/endarteritis and arrhythmias. Thrombosis within the fistula is rare but may cause acute myocardial infarction, paroxysmal atrial fibrillation and ventricular arrhythmias. Spontaneous rupture of the aneurysmal fistula causing haemopericardium has also been reported. The main differential diagnosis is patent arterial duct, although other congenital arteriovenous shunts need to be excluded. Whilst two-dimensional echocardiography helps to differentiate between the different shunts, coronary angiography is the main diagnostic tool for the delineation of the anatomy. Surgery was the traditional method of treatment but nowadays catheter closure is recommended using a variety of closure devices, such as coils, or other devices. With the catheter technique, the results are excellent with infrequent complications. Disease name and synonyms Coronary arterial fistulas Coronary arterial fistulas or malformations

Altered HRV has been associated with adverse outcomes in heart disease, but this has not been established in patients with acute chest pain.This study aimed to create a non-invasive, economical and risk-free method in the clinical evaluation and diagnosis of significant CAD among patients with unstable angina.Twenty-four-hour Holter recordings of 100 patients with ACS were initiated within 24 hours of admission at the emergency department; stress ECG was done for all patients while coronary angiography was done only for patients with abnormal stress test. Time domain, frequency domain, and nonlinear HRV were examined.The mean SDNN was statistically significantly lower in patients with abnormal stress test, many time and frequency domain HRV parameters was statistically lower in patients with significant coronary arteries obstruction. HRV measured close to the ACS onset may assist in risk stratification. HRV parameters may provide additional, incremental prognostic information to established assessment guidelines and possible early intervention in those patients.

    Monochorionic twins are subjected to specific complications which originate in either imbalance or abnormality of the single placenta serving two twins. This unequal placental sharing can cause complications including twin-twin transfusion syndrome (TTTS), twin anemia-polycythemia sequence (TAPS), selective intrauterine growth restriction or twin reversed arterial perfusion sequence (TRAP). Monochorionicity also makes the management of these specific complications as well as that of a severe malformation in one twin hazardous since the spontaneous death of one twin exposes the co-twin to a risk of exsanguination into the dead twin and its placenta. The latter is responsible for the death of the co-twin in up to 20% of the cases and in ischemic sequelae in about the same proportions in the survivors. Although the symptoms of all these complications are very different, the keystone of their management comes down to either surgical destruction of the inter-twin anastomoses on the chorionic plate when aiming at dual survival or selective and permanent occlusion of the cord of a severely affected twin aiming at protecting the normal co-twin. This can be best achieved by fetoscopic selective laser coagulation and bipolar forceps cord coagulation respectively. PMID:20855238

  3. Poincaré analysis of an overnight arterial oxygen saturation signal applied to the diagnosis of sleep apnea hypopnea syndrome

    International Nuclear Information System (INIS)

    The analysis of oxygen desaturations is a basic variable in polysomnographic studies for the diagnosis of sleep apnea. Several algorithms operating in the time domain already exist for sleep apnea detection via pulse oximetry, but in a disadvantageous way—they achieve either a high sensitivity or a high specificity. The aim of this study was to assess whether an alternative analysis of arterial oxygen saturation (SaO2) signals from overnight pulse oximetry could yield essential information on the diagnosis of sleep apnea hypopnea syndrome (SAHS). SaO2 signals from 117 subjects were analyzed. The population was divided into a learning dataset (70 patients) and a test set (47 patients). The learning set was used for tuning thresholds among the applied Poincaré quantitative descriptors. Results showed that the presence of apnea events in SAHS patients caused an increase in the SD1 Poincaré parameter. This conclusion was assessed prospectively using the test dataset. 90.9% sensitivity and 84.0% specificity were obtained in the test group. We conclude that Poincaré analysis could be useful in the study of SAHS, contributing to reduce the demand for polysomnographic studies in SAHS screening

    We report an 18-year-old boy with occipital horn syndrome who developed aneurysms of the splenic and hepatic arteries. Occipital horn syndrome, also called X-linked cutis laxa or Ehlers-Danlos syndrome (EDS) type IX, is characterised by a skeletal dysplasia which includes occipital horns, broad clavicles, deformed radii, ulnae and humeri, narrow rib cage, undercalcified long bones and coxa valga. Distinctive features common to all patients are unusual facial appearance, hypermobility of finger joints, limitation of extension of elbows, chronic diarrhoea and genitourinary abnormalities. In this case report we describe the difficulties encountered in the diagnostic management of patients with EDS-related vascular lesions. (orig.) With 5 figs., 2 tabs., 12 refs.

  5. CT-guided thoracal sympathicolysis for the treatment of peripheral arterial occlusive disease and chronic thoracal pain syndromes in 6 patients

    International Nuclear Information System (INIS)

    Purpose: Retrospective evaluation of the safety and effectivity of CT-guided percutaneous thoracal sympathicolysis (CT-TSL) in the treatment of patients with peripheral arterial occlusive disease (PAOD) of the upper limb and chronic thoracal pain syndromes. Comparison of our own experience with literature reports. Material and Methods: Between 6/96 and 12/99, 4 patients with PAOD of the upper limb and two with chronic thoracal pain syndromes caused by herpes zoster were treated by unilateral CT-TSL. Results: 18, 21 and 32 months after the intervention 3 out of 4 patients treated for PAOD reported subjective improvements, and one remained unchanged. Two patients treated for pain syndromes showed no long-term benefit of the procedure. There were no serious complications. Conclusion: The CT-TSL is an alternative method in the treatment of PAOD in patients who are unsuitable for treatment by revascularization. (orig.)

    After childhood Kawasaki syndrome (KS) the coronary arteries undergo a lifelong dynamic pathological change, and follow-up coronary artery imaging is essential. At present, conventional coronary catheterization (CCC) and angiography is still regarded as the gold standard. Less-invasive methods such as multidetector CT angiography (MDCT-A) and MRI have been used sporadically. To compare the diagnostic quality of MDCT-A and MRI with that of CCC for coronary imaging in a group of patients with coronary artery pathology after childhood KS. A total of 16 patients (aged 5-27 years) underwent CCC and 16-row MDCT-A and 14 patients MRI (1.5 T). There was 100% agreement between MDCT-A and CCC in the detection of coronary aneurysms and stenoses. MDCT-A was superior for the visualization of calcified lesions. MRI and CCC showed 93% agreement for the detection of aneurysms. Visualization of coronary artery stenoses was difficult using MRI - one stenosis was missed. MDCT-A has excellent correlation with CCC regarding all changes affecting the coronary arteries in the follow-up of childhood KS. In comparison to MDCT-A and CCC, MRI is less precise in the detection of stenotic lesions. Due to its high image quality and ease of performance MDCT-A should be the primary diagnostic modality in patients following childhood KS. (orig.)

  8. Effects of continuous administration of clopidogrel before off-pump coronary artery bypass grafting in patients with acute coronary syndrome. A propensity score analysis

    International Nuclear Information System (INIS)

    Clopidogrel has become standard treatment after urgent percutaneous coronary revascularization. Due to its enhanced and irreversible platelet inhibition, patients undergoing urgent surgical revascularization have a higher risk of bleeding complications and transfusions. Therefore, the effect of preoperative continuous administration of clopidogrel on the incidence of hemorrhagic complications in patients undergoing off-pump coronary artery bypass surgery with acute coronary syndrome was evaluated. From March 2004 to September 2006, 172 patients with acute coronary syndrome underwent isolated off-pump coronary artery bypass surgery; 70 (40.7%) and 102 (59.3%) of these patients did or did not take clopidogrel before surgery respectively. Seventy patients in each group were matched using propensity scores and associations between preoperative continuous administration of clopidogrel and postoperative bleeding, hemostatic reoperation, blood products received, the need for multiple transfusions and early graft patency by coronary computed tomography were assessed. Univariate analysis showed the continuous clopidogrel group had similar levels of postoperative bleeding for 24 h (601.4±312.6 ml vs 637.2±452.4 ml, p=0.616) and rates of reexploration (1.4% vs 1.4%), perioperative blood transfusion (33.3% vs 34.3%, p>0.05) and platelet transfusion (2.9% vs 7.1%, p=0.44) compared with the non-continuous group. Preoperative continuous administration of clopidogrel did not increase the risk of hemorrhagic complications in patients with acute coronary syndrome undergoing isolated off-pump coronary artery bypass surgery. These findings indicate that surgery after clopidogrel treatment in patients with acute coronary syndrome should not be delayed until platelet function returns to normal because they may have a higher risk of recurrent myocardial ischemic events.

    Early risk stratification in patients with non-ST elevation acute coronary syndromes (NSTE-ACS) is important since the benefit from more aggressive and costly treatment strategies is proportional to the risk of adverse clinical events. In the present study we assessed whether hybrid single photon emission computed tomography (SPECT)/coronary computed tomography angiography (CCTA) technology could be an appropriate tool in stratifying patients with NSTE-ACS. SPECT/CCTA was performed in 90 consecutive patients with NSTE-ACS. The Thrombolysis in Myocardial Infarction risk score (TIMI-RS) was used to classify patients as low- or high-risk. Imaging was performed using SPECT/CCTA to identify haemodynamically significant lesions defined as >50% stenosis on CCTA with a reversible perfusion defect on SPECT in the corresponding territory. CCTA demonstrated at least one lesion with >50% stenosis in 35 of 40 high-risk patients (87%) as compared to 14 of 50 low-risk patients (35%; TIMI-RS <3; p <0.0001). Of the 40 high-risk and 50 (16%) low-risk TIMI-RS patients, 16 (40%) and 8 (16%), respectively, had haemodynamically significant lesions (p = 0.01). Patients defined as high-risk by a high TIMI-RS, a positive CCTA scan or both (n = 45) resulted in a sensitivity of 95%, specificity of 49%, PPV of 35% and NPV of 97% for having haemodynamically significant coronary lesions. Those with normal perfusion were spared revascularization procedures, regardless of their TIMI-RS. Noninvasive assessment of coronary artery disease by SPECT/CCTA may play an important role in risk stratification of patients with NSTE-ACS by better identifying the subgroup requiring intervention.

    Symptoms of chronic mesenteric ischemia develop when the celiac artery is constricted by the median arcuate ligament of the diaphragm. Lateral aortography is the primary modality for diagnosing ligamentous compression of the celiac artery. However, duplex Doppler sonography performed during deep expiration can cause a marked increase in flow velocities at the compressed region of the celiac artery and suggest the diagnosis of celiac arterial constriction due to the diaphragmatic ligament.

Clinical indications were: vertebrobasilar insufficiency (n=57, upper limb ischemia (n=40, coronary steal syndrome (n=4 and scheduled aorto-coronary bypass, using internal thoracic artery (ITA (n=4 asymptomatic patients. Mean lesion length was 22 ± 8 mm. Results. Eighty one (87% out of 93 lesions were successfully dilated; all of 12 (13% failures were due to unsuccessful recanalisation of occluded arteries. In 10 patients 10 stents were implanted (2 in BT and 8 in left SA. There were 6 (6.5% procedural complications: 1 dissection, 1 thrombosis of the left SA, transient ischemic attack in 2 patients, and 2 cases of dislocation of atheromatous plaque from the right SA into the right common carotid artery. During the follow-up of 48 ± 3 months, 16 (20% restenoses were treated by PTA (n=7 or operatively (n=9. Primary and secondary patency for all lesions treated during 11 years was 87% and 80%, respectively (stenosis: 97% and 89%; occlusions: 58% and 58%. Conclusion. PTA with or without stenting was relatively simple, efficient and safe procedure. It required short hospitalization with low treatment costs. If any of suboptimal results or chronic occlusions were present, the implantation of endovascular stents should have been considered.

    This study explores the relationship between clinical cardiovascular risk factors and clinical androgen excess, with direct comparison to radial artery intima media thickness (rIMT). rIMT of 91 patients with polycystic ovary syndrome (PCOS) were compared with 72 healthy women. Patients were divided into three groups with regard to body mass index (BMI). Group1 = 56 women (31 controls and 25 PCOS) with low BMI(18-22.49 kg/m(2)), Group2 = 36 women (15 controls and 21 PCOS) with normal BMI (22.5-24.99 kg/m(2)) and Group3 = 71 women (26 controls and 45 PCOS) with high BMI (25-30 kg/m(2)). rIMT was significantly higher in patients with PCOS (p = 0.007). rIMT was significantly higher group1 and group3 in patients with PCOS compared to controls (p = 0.007 and p = 0.042, respectively). There was a significant positive association between rIMT levels and fT in women with PCOS in group1 (r = 0.24, p = 0.04). rIMT levels correlated to fT levels in women with PCOS in group3 (r = 0.32, p = 0.03). Modified Ferriman-Gallwey (mFG) scores demonstrated a positive association with free testosterone, total testosterone, free androgen index, waist circumference (WC), LH levels, insulin levels, Homeostasis Model Assessment index(HOMA-IR), rIMT and a negative correlation with sex hormone binding globulin in group1 and group2. mFG scores demonstrated a positive association with free testosterone (r = 0.33, p = 0.029) in group3, but no association was found between mFG and WC, HOMA-IR in group3. Our findings indicate that clinical androgen excess may be associated with cardiovascular disease in patients with PCOS. PMID:26213862

  3. Comparison of the TIMI and the GRACE risk scores with the extent of coronary artery disease in patients with non-ST-elevation acute coronary syndrome

    International Nuclear Information System (INIS)

    Objective: To compare the accuracy of the Global Registry of Acute Coronary Events risk score and the Thrombolysis In Myocardial Infarction risk score in predicting the extent of coronary artery disease in patients with non-ST segment elevation acute coronary syndrome. Methods: The cross-sectional study comprising 406 consecutive patients was conducted at the National Institute of Cardiovascular Diseases, Karachi, from August 2010 to March 2011. For all patients, the GRACE and TIMI RS's relevant scores on the two indices were calculated on admission using specified variables. The patients underwent coronary angiography to determine the extent of the disease. A significant level was defined as >70% stenosis in any major epicardial artery or >50% stenosis in the left main coronary artery. SPSS 19 was used for statistical analysis. Results: Both the indices showed good predictive value in identifying the extent of the disease. A Thrombolysis In Myocardial Infarction score >4 and Global Registry of Acute Coronary Events score >133 was significantly associated with 3vessel disease and left main disease, while for the former score <4 and latter score <133 was associated with normal or non-obstructive coronary disease (p<0.01). On comparison of the two risk scores, the discriminatory accuracy of the latter was significantly superior to the former in predicting 2vessel, 3vessel and left main diseases (p<0.05). Conclusion: Although both the indices were helpful in predicting the extent of the disease, the Global Registry showed better performance and was more strongly associated with multi-vessel and left main coronary artery disease.

    We present a case of severe headache occurring after a TEVAR with intentional coverage of the origin of the left SCA. This headache was the only symptom from which the patient complained, and which disappeared immediately after carotid-SCA bypass. Other devastating complications can happen, which gave as a concern about the management of SCA when decision to practice a TEVAR is taken.

    Full Text Available Abstract Background Coronary artery disease (CAD is among the main causes of death in developed countries, and diet and lifestyle can influence CAD incidence. Objective To evaluate the association of coronary artery disease risk score with dietary, anthropometric and biochemical components in adults clinically selected for a lifestyle modification program. Methods 362 adults (96 men, 266 women, 53.9 ± 9.4 years fulfilled the inclusion criteria by presenting all the required data. The Framingham score was calculated and the IV Brazilian Guideline on Dyslipidemia and Prevention of Atherosclerosis was adopted for classification of the CAD risks. Anthropometric assessments included waist circumference (WC, body fat and calculated BMI (kg/m2 and muscle-mass index (MMI kg/m2. Dietary intake was estimated through 24 h dietary recall. Fasting blood was used for biochemical analysis. Metabolic Syndrome (MS was diagnosed using NCEP-ATPIII (2001 criteria. Logistic regression was used to determine the odds of CAD risks according to the altered components of MS, dietary, anthropometric, and biochemical components. Results For a sample with a BMI 28.5 ± 5.0 kg/m2 the association with lower risk ( Conclusion Recommended intake of saturated fat and dietary fiber, together with proper muscle mass, are inversely associated with CAD risk score. On the other hand, the presence of MS and high plasma uric acid are associated with CAD risk score.

    Background Recent research suggested that obstructive sleep apnea syndrome (OSAS) might be independently associated with hypoadiponectinemia, which was linked to some complications of OSAS, such as hypertension, diabetes,etc. This study was conducted to investigate the effect of continuous positive airway pressure (CPAP) treatment on changes of both serum adiponectin levels and mean arterial pressure and their possible links in male OSAS patients.Methods Twenty-three adult male patients with moderate-to-severe OSAS but without obesity, coronary heart disease and diabetes were recruited. Their blood sampleswere collected and moming mean arterial pressure (MAP) was measured before CPAP treatment and on day 3, 7, 14 of CPAP treatment respectively. The serum adiponectin concentration was tested with radioimmunoassay.Results Compared with the serum adiponectin level before CPAP treatment, no significant change was found in OSAS patients on day 3 and day 7 of CPAP treatment (P>0.05). It was not until day 14 of CPAP treatment did a significant elevation in serum adiponectin level occur (P<0.01). Meanwhile, the MAP showed no statistically significant difference among its levels before CPAP, on day 3 and day 7 of CPAP treatment (P>0.05). However, on day 14 of CPAP treatment,a significantly lower MAP than that obtained before treatment was observed (P<0.05).Conclusions CPAP treatment can gradually reverse hypoadiponectinemia and reduce MAP in OSAS patients.Hypoadiponectinemia might be involved in the pathogenesis of OSAS-mediated hypertension.

    Kounis syndrome is characterised by a group of symptoms that manifest as unstable vasospastic or non-vasospastic angina secondary to a hypersensitivity reaction. It was first described by Kounis and Zavras in 1991 as the concurrence of an allergic response with an anaphylactoid or anaphylactic reaction and coronary artery spasm or even myocardial infarction. Since then, this condition has evolved to include a number of mast cell activation disorders associated with acute coronary syndrome. There are many triggering factors, including reactions to multiple medications, exposure to radiological contrast media, poison ivy, bee stings, shellfish and coronary stents. In addition to coronary arterial involvement, Kounis syndrome comprises other arterial systems with similar physiologies, such as mesenteric and cerebral circulation resulting in ischaemia/infarction of the vital organs. The incidence of this condition is difficult to establish owing to the number of potential instigating factors and its relatively infrequent documentation in the literature.We report the case of an HIV-negative 39-year-old man with no coronary risk factors or family history of premature coronary artery disease, who developed Kounis syndrome after the administration of fluoroquinolone for dysuria. However, to the best of our knowledge,no data on the incidence and prevalence of Kounis syndrome in South Africa have ever been reported in the literature. The recent understanding of Kounis syndrome has led to the condition being classified into three syndrome variants. PMID:26636160

To study the endothelium status and determine the correlation between endothelial dysfunction and glucose metabolism in men with gout associated with arterial hypertension (HT.Material and methods. Patients (n=175, all are males with gout were enrolled into the study. Ambulatory blood pressure monitoring (ABPM was performed in all patients. Endothelial function was studied in tests with reactive hyperemia (endothelium-dependent reaction and nitroglycerin (endothelium independent reaction in brachial artery by ultrasonic Doppler examination. The level of nitrite-nitrate and endothelin-1 in blood serum was determined by ELISA technique. Fasting blood glucose and oral glucose tolerance tests were performed as well as fasting insulin blood level was determined by immunoenzyme method. Insulin-resistance index (HOMA-IR was calculated. Patients with HOMA- IR>2.77 were considered as insulin-resistant.Results. Patients with gout demonstrated endothelial deterioration associated with activation of nitroxid producing function, elevation in endothelin-1 serum level (1.36 fmol/ml [0.91; 2.32 fmol/ml] vs 0.19 fmol/ml [0.16; 0.27 fmol/ml] in controls, p<0.05 and impairments of endothelium-dependent vasodilation (6.4% [3.3; 7.3%] vs 17.8% [12.7; 23.9%] in controls, p<0.05. The revealed changes were the most marked in patients with gout associated with HT. The correlation between some endothelial dysfunction in- dices and glucose metabolism was observed.Conclusion. ABPM, brachial artery endothelium-dependent vasodilation and glucose metabolism status should be studied in patients with gout. Complex treatment of cardiovascular diseases in patients with gout should include ω-3 polyunsaturated fatty acids, angiotensin receptor antagonists should be used for antihypertensive therapy.

    2012-02-01

    Full Text Available Abstract Background MELAS syndrome (MIM ID#540000, an acronym for Mitochondrial Encephalopathy, Lactic Acidosis and Stroke-like episodes, is a genetically heterogeneous mitochondrial disorder with protean manifestations and occasional kidney involvement. Interest in the latter is rising due to the identification of cases with predominant kidney involvement and to the hypothesis of a link between mitochondrial DNA and kidney neoplasia. Case presentation We report the case of a 41-year-old male with full blown MELAS syndrome, with lactic acidosis and neurological impairment, affected by the "classic" 3243A > G mutation of mitochondrial DNA, with kidney cancer. After unilateral nephrectomy, he rapidly developed severe kidney functional impairment, with nephrotic proteinuria. Analysis of the kidney tissue at a distance from the two tumor lesions, sampled at the time of nephrectomy was performed in the context of normal blood pressure, recent onset of diabetes and before the appearance of proteinuria. The morphological examination revealed a widespread interstitial fibrosis with dense inflammatory infiltrate and tubular atrophy, mostly with thyroidization pattern. Vascular lesions were prominent: large vessels displayed marked intimal fibrosis and arterioles had hyaline deposits typical of hyaline arteriolosclerosis. These severe vascular lesions explained the different glomerular alterations including ischemic and obsolescent glomeruli, as is commonly observed in the so-called "benign" arteriolonephrosclerosis. Some rare glomeruli showed focal segmental glomerulosclerosis; as the patient subsequently developed nephrotic syndrome, these lesions suggest that silent ischemic changes may result in the development of focal segmental glomerulosclerosis secondary to nephron loss. Conclusions Nephron loss may trigger glomerular sclerosis, at least in some cases of MELAS-related nephropathy. Thus the incidence of kidney disease in the "survivors" of MELAS

    In the case of non-ST-segment elevation acute coronary syndromes (NSTE-ACSs), the acute use of certain antiplatelet agents is complicated by concerns about perioperative bleeding risks in patients requiring coronary artery bypass grafting (CABG) during the index hospitalization. As a result, clinicians often withhold potentially useful agents, such as clopidogrel, before determining patients' coronary anatomy. An accurate predictive model could allow for a better balance of this safety concern with the demonstrated benefits of agents such as clopidogrel. To create an accurate decision-making tool that would assess, at hospital presentation, the need for CABG in patients with NSTE-ACSs, we studied 61,974 high-risk patients with NSTE-ACS admitted to 311 CABG-capable hospitals participating in Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the American College of Cardiology/American Heart Association Guidelines (CRUSADE) from 2001 to 2003. A total of 8,395 patients (14%) underwent CABG during their initial hospital stay. A multivariate model was developed and identified 13 presenting clinical characteristics significantly associated with the likelihood of CABG (previous CABG, male gender, previous heart failure, diabetes, hyperlipidemia, renal insufficiency, ST depression and transient ST elevation, age > or = 75 years, previous percutaneous coronary intervention, family history of coronary artery disease, hypertension, trends in CABG rates, and previous stroke). This model had only modest predictive accuracy and calibration (c-index = 0.67). In conclusion, although certain presenting clinical features are associated with an increased likelihood of CABG in patients with NSTE-ACSs during the index hospitalization, it remains difficult to reliably identify, before diagnostic angiography, those who will subsequently undergo surgical revascularization.

    Conclusion Multi-level surgeries for the nasal cavity and palate can reduce the severity of obstructive sleep apnea with major narrowing above the retropalatal airway and reduce the carotid intima-media thickness, which can provide cardiovascular benefits to patients. Objective To evaluate the outcomes of moderate-to-severe obstructive sleep apnea syndrome by surgeries and the change of internal carotid artery intima-media thickness after surgeries. Subjects and methods Sixty-four patients with obstructive sleep apnea, narrowing at the nasal cavity, and retropalatal airways were enrolled in this study. Fifty-two patients underwent nasal surgery and modified uvulopalatopharyngoplasty. Twelve patients who refused surgeries and continuous positive airway pressure treatment received only conservative treatment. All patients were evaluated within 1 month before and 6 months after treatment using polysomnography, upper airway endoscopy, and B mode ultrasound. Results The success rate was 61.5% (32/52 patients) in the surgery group. There were significant differences between the surgery group and non-surgery group 6 months after treatment in the apnea hypopnea index, minimum and mean oxygen saturation, blood pressure, triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and internal Carotid intima-media thickness. The changes in the oxygen saturation and the apnea hypopnea index showed significant correlations with the changes in the intima-media thickness. PMID:26824298

    Chronic kidney disease (CKD) and end-stage renal disease (ESRD) have emerged as a worldwide public health problem. Due to the remarkably higher incidence and prevalence of this chronic disease in Taiwan than in other countries, CKD/ESRD has contributed to a significant health burden in Taiwan. Patients with CKD/ESRD have an increased risk of coronary artery disease (CAD) and acute coronary syndrome (ACS) compared to the normal population. Patients with ACS alone can present differently than patients with ACS and CKD/ESRD. Also, due to the lower prevalence of chest pain and ST-segment elevation, CKD/ESRD patients were more difficult to diagnose than other patients. Furthermore, whether advances in ACS management with medical therapy and an early invasive approach could improve patient outcomes with CKD/ESRD is not known. The use of antiplatelets such as aspirin and other antithrombotic agents might reduce the incidence of ACS or stroke in CKD patients. However, such use could also increase bleeding risk and even increase the likelihood of mortality, especially in dialysis patients. While recent clinical data suggest the potential benefit of aggressive management with coronary intervention for CAD and ACS in this category of patients, further clinical studies are still indicated for the proper medical strategy and revascularization therapy to improve the outcomes of CAD and ACS in CKD/ESRD patients, both in Taiwan and worldwide.

    Sequence homology detection is central to a number of bioinformatics applications including genome sequencing and protein family characterization. Given millions of sequences, the goal is to identify all pairs of sequences that are highly similar (or “homologous”) on the basis of alignment criteria. While there are optimal alignment algorithms to compute pairwise homology, their deployment for large-scale is currently not feasible; instead, heuristic methods are used at the expense of quality. Here, we present the design and evaluation of a parallel implementation for conducting optimal homology detection on distributed memory supercomputers. Our approach uses a combination of techniques from asynchronous load balancing (viz. work stealing, dynamic task counters), data replication, and exact-matching filters to achieve homology detection at scale. Results for 2.56M sequences on up to 8K cores show parallel efficiencies of ~ 75-100%, a time-to-solution of 33s, and a rate of ~ 2.0M alignments per second.

    AIM:To investigate the contribution of anti-platelet therapy and derangements of pre-operative classical coagulation and thromboelastometry parameters to major bleeding post-coronary artery bypass grafting(CABG).METHODS:Two groups of CABG patients were studied:Group A,treated with aspirin alone(n=50),and Group B treated with aspirin and clopidogrel(n=50).Both had similar preoperative,clinical,biologic characteristics and operative management.Classic coagulation parameters and rotational thromboelastometry(ROTEM)profiles were determined preoperatively for both groups and the same heparin treatment was administered.ROTEM profiles(INTEM and EXTEM assays)were analyzed,both for traditional parameters,and thrombin generation potential,expressed by area-under-curve(AUC).RESULTS:There was no significant difference betweenrates of major bleeding between patients treated with aspirin alone,compared with those treated with aspirin and clopidogrel(12%vs 16%,P=0.77).In the 14 cases of major bleeding,pre-operative classic coagulation and traditional ROTEM parameters were comparable.Conversely we observed that the AUC in the EXTEM test was significantly lower in bleeders(5030±1115 Ohm*min)than non-bleeders(6568±548Ohm*min)(P<0.0001).CONCLUSION:We observed that patients with a low AUC value were at a significantly higher risk of bleeding compared to patients with higher AUC,regardless of antiplatelet treatment.This suggests that thrombin generation potential,irrespective of the degree of platelet inhibition,correlates with surgical bleeding.

    The initial hypoxemic level of acute respiratory distress syndrome (ARDS) defined according to Berlin definition might not be the optimal predictor for prognosis. We aimed to determine the predictive validity of the stabilized ratio of partial pressure arterial oxygen and fraction of inspired oxygen (PaO2/FiO2 ratio) following standard ventilator setting in the prognosis of patients with ARDS.This prospective observational study was conducted in a single tertiary medical center in Taiwan and compared the stabilized PaO2/FiO2 ratio (Day 1) following standard ventilator settings and the PaO2/FiO2 ratio on the day patients met ARDS Berlin criteria (Day 0). Patients admitted to intensive care units and in accordance with the Berlin criteria for ARDS were collected between December 1, 2012 and May 31, 2015. Main outcome was 28-day mortality. Arterial blood gas and ventilator setting on Days 0 and 1 were obtained.A total of 238 patients met the Berlin criteria for ARDS were enrolled, and they were classified as mild (n = 50), moderate (n = 125), and severe (n = 63) ARDS, respectively. Twelve (5%) patients who originally were classified as ARDS did not continually meet the Berlin definition, and a total of 134 (56%) patients had the changes regarding the severity of ARDS from Day 0 to Day 1. The 28-day mortality rate was 49.1%, and multivariate analysis identified age, PaO2/FiO2 on Day 1, number of organ failures, and positive fluid balance within 5 days as significant risk factors of death. Moreover, the area under receiver-operating curve for mortality prediction using PaO2/FiO2 on Day 1 was significant higher than that on Day 0 (P = 0.016).PaO2/FiO2 ratio on Day 1 after applying mechanical ventilator is a better predictor of outcomes in patients with ARDS than those on Day 0.

    The clinical manifestations of coronary artery anomalies vary in severity, with some anomalies causing severe symptoms and cardiovascular sequelae and others being benign. Cardiovascular computed tomography (CT) has emerged as the standard of reference for identification and characterization of coronary artery anomalies. Therefore, it is important for the reader of cardiovascular CT images to be thoroughly familiar with the spectrum of coronary artery anomalies. Hemodynamically significant anomalies include atresia, origin from the pulmonary artery, interarterial course, and congenital fistula. Non-hemodynamically significant anomalies include duplication; high origin; a prepulmonic, transseptal, or retroaortic course; shepherd's crook right coronary artery; and systemic termination. In general, coronary arteries with an interarterial course are associated with an increased risk of sudden cardiac death. Coronary artery anomalies that result in shunting, including congenital fistula and origin from the pulmonary artery, are also commonly symptomatic and may cause steal of blood from the myocardium. Radiologists should be familiar with each specific variant and its specific constellation of potential implications. PMID:22411942

    Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological entity affecting both adults and children characterized by neurotoxicity often in setting of hypertension coupled with distinct brain magnetic resonance imaging features. Decreased serum albumin level has been suggested to correlate with the presence of vasogenic brain edema in adult PRES. Serum albumin has thus been hypothesized to protect against neurotoxicity in PRES by reducing vasogenic brain edema through its role in maintaining plasma osmotic pressure and endothelial integrity. The purpose of our study was to investigate if such correlation between decreased serum albumin level and PRES-related vasogenic edema could be found in children. We conducted a retrospective study of 25 pediatric patients diagnosed with PRES. Underlying clinical conditions, presenting symptoms, blood pressures, and serum albumin levels at onset of symptoms were collected. Brain MR imaging studies were reviewed. We used a quantitative method to evaluate the degree of vasogenic edema by measuring apparent diffusion coefficient (ADC) values of the T2-FLAIR hyperintense brain lesions. No significant correlation was found between serum albumin level and degree of PRES-related vasogenic edema. A significant correlation was found between elevated blood pressure and degree of vasogenic edema in the temporal lobes (p = 0.02 and 0.04, respectively) but not in the other cerebral lobes or cerebellum. Our initial results suggest blood pressure, not serum albumin level, as a main biomarker for brain edema in children with PRES. Thus, our study does not suggest a protective role of serum albumin against PRES-related neurotoxicity in children. (orig.)

    Acute coronary artery syndrome (ACS) is the major cause of mortality in Pakistan with genetic and environmental influence on the incidence of the disease. This case-control study was designed to find out if a correlation is existing between ACS and single nucleotide polymorphisms (SNPs) in DNA repair genes XPD [at codon 751, rs 13181 (Lys to Gln)] and XRCC1 [at codon 399, rs25487 (Arg to Gln); 280, rs25489 (Arg to His) and 194, rs 1799782 (Arg to Trp)] either individually or in various combination with each other (haplotype analysis). The objective of this study was to find out the association of various studied risk factors and serum lipid profile of the subjects with the disease, if any. PCR-RFLP method was used to determine genotype at specific codon in 221 subjects (115 ACS patients and 106 healthy controls) from Southern Punjab population. Genotypic and allelic frequency distribution among the cases and controls revealed that all the studied SNPs were not individually associated with the ACS. Haplotype analysis revealed that subjects having wild type combination of all three XRCC1 SNPs had greater susceptibility to ACS than any other studied genotypic combinations. Analysis of risk factors revealed that hypertension (Peducation (Pgender (P<0.001), family history (P=0.005), smoking habit (P=0.002) and diabetes (P<0.001) were significantly associated with the incidence of ACS. Serum lipid profile analysis indicated that cholesterol level was significantly higher (P=0.048) in patients (161.5mg/dL) than controls (142.1mg/dL) while triglyceride remained unaffected (P=0.87) when compared between the two treatments.

  11. Evaluation of the outcomes of endovascular management for patients with head and neck cancers and associated carotid blowout syndrome of the external carotid artery

    International Nuclear Information System (INIS)

    Aim: To evaluate factors related to the technical and haemostatic outcomes of endovascular management in patients with head and neck cancers (HNC) associated with carotid blowout syndrome (CBS) of the external carotid artery (ECA). Materials and methods: Between 2002 and 2011, 34 patients with HNC with CBS involving branches of the ECA underwent endovascular therapy. Treatment included embolization with microparticles, microcoils, or acrylic adhesives. Fisher's exact test was used to examine demographic features, clinical and angiographic severities, and clinical and imaging findings as predictors of endovascular management outcomes. Results: Technical success and immediate haemostasis were achieved in all patients. Technical complications were encountered in one patient (2.9%). Rebleeding occurred in nine patients (26.5%). Angiographic vascular disruption grading from slight (1) to severe (4) revealed that the 18 patients with acute CBS had scores of 2 (2/18, 11.1%), 3 (3/18, 16.7%), and 4 (13/18, 72.2%). The 16 patients with impending and threatened CBS had scores of 1 (1/16, 6.25%), 2 (5/16, 31.25%), and 3 (10/16, 62.5%; p = 0.0003). For the 25 patients who underwent preprocedural computed tomography (CT)/magnetic resonance imaging (MRI) examinations within 3 months of treatment, the agreement between clinical and imaging findings reached the sensitivity, specificity, and kappa values for recurrent tumours (1, 0.7143, 0.7826), soft-tissue defect (0.9091, 0.3333, 0.2424), and sinus tract/fistula (0.4737, 0, 0.4286). Conclusion: Endovascular management for patients with CBS of the ECA had high technical success and safety but was associated with high rebleeding rates. We suggest applying aggressive post-procedural follow-up and using preprocedural CT/MRI to enhance the periprocedural diagnosis

    The indigenous South African mussel Perna perna gapes during periods of aerial exposure to maintain aerobic respiration. This behaviour has no effect on the body temperatures of isolated individuals, but when surrounded by conspecifics, beneficial cooling effects of gaping emerge. It is uncertain, however, whether the presence of the invasive mussel Mytilus galloprovincialis limits the ability of P. perna for collective thermoregulation. We investigated whether varying densities of P. perna and M. galloprovincialis influences the thermal properties of both natural and artificial mussel beds during periods of emersion. Using infrared thermography, body temperatures of P. perna within mixed artificial beds were shown to increase faster and reach higher temperatures than individuals in conspecific beds, indicating that the presence of M. galloprovincialis limits the group cooling effects of gaping. In contrast, body temperatures of M. galloprovincialis within mixed artificial mussel beds increased slower and exhibited lower temperatures than for individuals in beds comprised entirely of M. galloprovincialis. Interestingly, differences in bed temperatures and heating rates were largely dependent on the size of mussels, with beds comprised of larger individuals experiencing less thermal stress irrespective of species composition. The small-scale patterns of thermal stress detected within manipulated beds were not observed within naturally occurring mixed mussel beds. We propose that small-scale differences in topography, size-structure, mussel bed size and the presence of organisms encrusting the mussel shells mask the effects of gaping behaviour within natural mussel beds. Nevertheless, the results from our manipulative experiment indicate that the invasive species M. galloprovincialis steals thermal properties as well as resources from the indigenous mussel P. perna. This may have significant implications for predicting how the co-existence of these two species may

    Full Text Available Partindo do trabalho pioneiro de J. Piaget, O julgamento moral da criança, revisamos as contribuições para este estudo sobre a concepção de roubo em crianças. Usando uma história que envolve um pequeno roubo examinamos como pré-escolares respondem a questões sobre o roubo ser certo ou errado, o porquê dessa resposta, assim como avaliamos a percepção da criança à presença, à contingência e à relatividade de regras. Tendo como sujeitos 80 crianças de duas pré-escolas, uma pública e outra particular, cada escola dividida em duas turmas, encontramos que todas as crianças têm noção da regra de o roubo ser errado e ao justificarem essa resposta apresentam cinco tipos de argumentos, assim como já apresentam julgamentos em função da intenção. Resultados são discutidos em termos da teoria de desenvolvimento moral de Piaget.From the pioneering work of J. Piaget "The moral judgment of the child" we have reviewed the contributions to this study of childrens' conception of stealing . Using a story about a minor theft, we examined how kindergarten children answer questions about the right and wrong of stealing and now they justified their answers. In addition we examined childrens' perception of the existence, contingence and relativity of rules. We examined 80 children from a public and a private school, each divided in two groups. The results have shown that children have a notion of stealing as a wrong act and to justify these answers they show five patterns of justifications, as well as judgment of intentionality. Results were discussed in terms of Piaget's moral development theory.

    Background Although the severity of inducible ischemia provides incremental prognostic information in persons with known or suspected coronary artery disease (CAD), its significance for predicting long-term CAD outcomes in apparently healthy populations is unknown. This study was designed to evaluate the presence and degree of myocardial ischemia in asymptomatic siblings of persons with premature CAD <60 years of age and to determine its significance for predicting incident acute coronary syndromes (ACS) during follow-up of 5 to 25 years. Methods Siblings (n = 1,287, age 30-59 years, 55% female) were screened for traditional risk factors, underwent exercise treadmill testing with nuclear perfusion imaging, and were followed for the development of ACS (mean follow-up 11.6 ± 5.1 years). The severity of ischemia was assessed by semiquantitative methods using the standard 17-segment model and then categorized by the percent maximal summed stress score as none (0%), minimal (1% to <5%), mild (5% to 10%), moderate (10% to 15%), or severe (≥15%). Results ACS occurred in 132 subjects (10.3%) and included sudden cardiac death (n = 13), acute MI (n = 62), and unstable angina with revascularization (n = 57). The presence of no (88%), minimal (6%), mild (5%), and moderate/severe (1%) ischemia was associated with an ACS incidence of 8.3%, 19.7%, 25.0%, and 38.9%, respectively (P < .0001 for trend). Kaplan-Meier event-free survival analyses by myocardial ischemia severity categories showed that even minimal and mild myocardial ischemia were associated with greater ACS incidence detectable as early as 2 years after baseline. A Cox proportional hazard model, adjusted for risk factors and follow-up time, showed that each 5% increment in the severity of ischemia resulted in a 77% increase in the hazard of incident ACS (P < .001). Conclusion Inducible myocardial ischemia is prevalent in asymptomatic siblings of persons with early onset CAD. Most ischemia is minimal or mild in

    Full Text Available A 71-year-old woman with chest pain occurring on physicalexercise was admitted to cardiology department.Myocardial perfusion scintigraphy revealed inferior andanteroapical segment hypoperfusion. Selective coronaryangiography revealed multiple coronary-cameral fistulasoriginating from the left anterior descending artery andthe right coronary artery and emptying into the left ventriclewithout any significant coronary artery stenosis. Coronaryartery fistulas are defined as abnormal communicationsbetween a coronary artery and a cardiac chamber ormajor vessel. Coronary-cameral fistulas terminating in theleft ventricle are uncommon. Small fistulas usually do notcause any hemodynamic compromise. However, the largerand multiple fistulas may cause myocardial ischemiaascribed to a coronary steal phenomenon. The best wayto manage cameral fistulae is uncertain largely due to therarity of the condition. In the present case, anti-ischemicmedications with metoprolol 50 mg/day provided an uneventfulfollow-up of six months without any intervention.

    uniform definition of this pathology. Aneurysms of the left main coronary artery (LMCA) are extremely uncommon, with an incidence of 0.1%. It has been demonstrated that atherosclerosis is the main cause of these anomalies in adults, and Kawasaki disease in children and adolescents. Other causes include connective tissue disorders, trauma, vasculitis, congenital, mycotic, and idiopathic. These dilated sections of the coronary artery are not benign pathology because they are subject to spasm, thrombosis, and subsequent distal embolism, spontaneous dissection and rupture. Treatment options include anticoagulation, custom-made covered stents, reconstruction, resection, and exclusion with bypass. Our report on an old case illustrates the giant saccular LMCA aneurysm leading to myocardial ischemia due to coronary steal phenomenon.

  19. Asymptomatic acute ischemic stroke after primary percutaneous coronary intervention in patients with acute coronary syndrome might be caused mainly by manipulating catheters or devices in the ascending aorta, regardless of the approach to the coronary artery

    International Nuclear Information System (INIS)

    Asymptomatic acute ischemic stroke (aAIS) following primary percutaneous coronary intervention (p-PCI) in patients with acute coronary syndrome (ACS) has not been studied in detail. Of 75 patients who underwent p-PCI, 26 (34.7%) developed aAIS as determined by diffusion-weighted magnetic resonance imaging (MRI). Including the approach to the coronary artery (via lower limb or right upper limb), 23 factors were compared between patients with (n=26) and without (n=49) aAIS. Age, hypertension, smoking, plasma glucose levels, Killip grade, right coronary artery (RCA) as culprit vessel, percutaneous coronary intervention (PCI) time, and the frequency of device insertion into the coronary artery differed in a statistically significant manner. However, multivariate analysis showed that the RCA (odds ratio 3.477) and the frequency of device insertion (1.375) were independent factors linked to the incidence of aAIS. Moreover, anterior or posterior location and left or right cerebral circulation of aAIS were equivalent in both approaches. Cranial MRI images following emergency PCI revealed that 34.7% of the patients with ACS had aAIS that might be caused by manipulating the catheter or devices in the ascending aorta, micro-air bubble embolism during injection, or micro-thrombus embolism derived from the ACS lesions during the PCI procedure.

    Hepatopulmonary syndrome is characterized by the presence of liver disease, pulmonary vascular dilatations, and arterial hypoxemia. It is usually associated with cirrhosis of any origin, but has been described in other liver diseases, both acute and chronic, and not always associated with portal hypertension. The gold standard method to detect pulmonary vascular dilations is contrast enhancement echocardiography with saline and is essential for the diagnosis of hepatopulmonary syndrome. These dilatations reflect changes in the pulmonary microvasculature (vasodilatation, intravascular monocyte accumulation, and angiogenesis) and induce a ventilation/perfusion mismatch, or even true intrapulmonary shunts, which eventually trigger hypoxemia. This syndrome worsens patients' prognosis and impairs their quality of life and may lead to the need for liver transplantation, which is the only effective and definitive treatment. In this article, we review the etiological, pathophysiological, clinical and therapeutic features of this syndrome. PMID:25840463

    The antiphospholipid syndrome causes venous, arterial, and small-vessel thrombosis; pregnancy loss; and preterm delivery for patients with severe pre-eclampsia or placental insufficiency. Other clinical manifestations are cardiac valvular disease, renal thrombotic microangiopathy, thrombocytopenia, haemolytic anaemia, and cognitive impairment. Antiphospholipid antibodies promote activation of endothelial cells, monocytes, and platelets; and overproduction of tissue factor and thromboxane A2. Complement activation might have a central pathogenetic role. Of the different antiphospholipid antibodies, lupus anticoagulant is the strongest predictor of features related to antiphospholipid syndrome. Therapy of thrombosis is based on long-term oral anticoagulation and patients with arterial events should be treated aggressively. Primary thromboprophylaxis is recommended in patients with systemic lupus erythematosus and probably in purely obstetric antiphospholipid syndrome. Obstetric care is based on combined medical-obstetric high-risk management and treatment with aspirin and heparin. Hydroxychloroquine is a potential additional treatment for this syndrome. Possible future therapies for non-pregnant patients with antiphospholipid syndrome are statins, rituximab, and new anticoagulant drugs. PMID:20822807

    Full Text Available Abstract Preoperative medication by inhibitors of angiotensin-converting enzyme (ACE in coronary artery patients predisposes to vasoplegic shock early after coronary artery bypass grafting. Although in the majority of the cases this shock is mild, in some of them it appears as a situation, "intractable" to high-catecholamine dose medication. In this study we examined the possible role of prophylactic infusion of low-dose vasopressin, during and for the four hours post-bypass after cardiopulmonary bypass, in an effort to prevent this syndrome. In addition, we studied the influence of infused vasopressin on the hemodynamics of the patients, as well as on the postoperative urine-output and blood-loss. In our study 50 patients undergoing coronary artery bypass grafting were included in a blind-randomized basis. Two main criteria were used for the eligibility of patients for coronary artery bypass grafting: ejection fraction between 30-40%, and patients receiving ACE inhibitors, at least for four weeks preoperatively. The patients were randomly divided in two groups, the group A who were infused with 0.03 IU/min vasopressin and the group B who were infused with normal saline intraoperativelly and for the 4 postoperative hours. Measurements of mean artery pressure (MAP, central venous pressure (CVP, systemic vascular resistance (SVR, ejection fracture (EF, heart rate (HR, mean pulmonary artery pressure (MPAP, cardiac index (CI and pulmonary vascular resistance (PVR were performed before, during, and after the operation. The requirements of catecholamine support, the urine-output, the blood-loss, and the requirements in blood, plasma and platelets for the first 24 hours were included in the data collected. The incidence of vasodilatory shock was significantly lower (8% vs 20% in group A and B respectively (p = 0,042. Generally, the mortality was 12%, exclusively deriving from group B.

    Full Text Available Many hypertensive patients affected by endogenous Cushing's syndrome (CS persist with high blood pressure (HBP despite good control of cortisol excess. We assessed the effect of preoperative ketoconazole administration and of definitive treatment of CS on arterial hypertension and analysed the factors involved in the persistence of hypertension. We assessed retrospectively 71 patients with CS and HBP (60 women, 11 men; 50 pituitary, 21 adrenal successfully treated by surgery and/or radiotherapy; 19 of them received ketoconazole (KNZ before surgery. After treatment, patients were divided into those with persistent high blood pressure (PHBP and those with normal blood pressure (NBP. As possible predictive factors for PHBP we analysed age, duration and family history of HBP, pre-treatment 24 hour urinary free cortisol (24h-UFC and body mass index (BMI. HBP normalized in 53 out of 71 patients (74.6%, regardless of the origin of Cushing's syndrome. PHBP patients were older (p=0.003, had longer duration (p=0.007 and higher systolic blood pressure before treatment (p=0.046 than NBP patients.

    Methods: This study was carried out in an urban population, aged 20 to 74 years, from Yazd, a city in the center of Iran. The study is a part of the phase I of Yazd Healthy Heart Program, that is, a community-based intervention study for the prevention of cardiovascular disease. The significance level has been defined as P<0.05. Results: Prevalence of the metabolic syndrome by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III criteria was 21.3 ± .017%, and by International Diabetes Federation (IDF criteria it was 30.16 ± .02%. The multivariate analysis showed that the most important relevant factors of diabetes mellitus were: Increased age and metabolic syndrome by both definitions of NCEP and IDF criteria, and also, the most important relevant factors of stable angina were: Increased age, male sex, and metabolic syndrome by only IDF definitions, but the NCEP definition of the metabolic syndrome cannot predict diabetes mellitus independent of age and sex. Conclusion: This study showed that increased age and metabolic syndrome are the most important relevant factors for diabetes mellitus, especially by using the IDF criteria for definition of the metabolic syndrome.

  13. Nutcracker syndrome

    International Nuclear Information System (INIS)

    Purpose: The purpose of this case study is to highlight the symptoms of the Nutcracker Syndrome (NCS), the methods of clinical investigations and the importance of differential diagnosis. Introduction: The NCS refers to left renal vein entrapment caused by abnormal branching patterns of the superior mesenteric artery from the aorta.1,2 Clinical case presentation: A 27 years old female presented to the emergency department with complaints of abdominal discomfort, bloating, loose bowel motions and irregular micro-haematuria. The radiologist's report indicated the findings from computed tomography examination to be consistent with anterior NCS. Discussion: In most of the NCS cases the clinical symptoms are non-specific.3 The syndrome is caused by a vascular disorder, but its clinical manifestation can relate to a wide range of abdominal, urological, endovascular or gynaecological pathologies.4 Conclusion: Nutcracker Syndrome is a relatively rare disease and underdiagnosed may lead to left renal vein thrombosis

    2004-01-01

    We describe a patient with ascending tetraparesis following stroke. The patient presented initially with spastic paraparesis which acutely evolved to tetraparesis with abulia. Magnetic resonance imaging revealed acute infarctions in the bilateral medial frontal regions but not in the brainstem or spinal cord. Multiple infarctions in the anterior cerebral artery territory appeared to originate from artery to artery embolism. The present case provides distinct clinical features of anterior cerebral artery syndrome which mimic myelopathy or brainstem lesions. PMID:17903956

    Full Text Available Kawasaki disease (KD is an acute vasculitis syndrome of unknown etiology. It occurs in infants and young children,affecting mainly small and medium-sized arteries, particularly the coronary arteries. Generalized microvasculitis occurs in the first 10 days, and the inflammation persists in the walls of medium and small arteries, especially the coronary arteries, and changes to coronary artery aneurysms.We report the case of a 10-month-old girl referred to our center three months after the onset of disease due to the aneurysmsof the coronary arteries. During the acute phase of her illness, she received 2 gr/kg intravenous gamma globulin; and afterher referral to us, the patient was treated by antiaggregant doses of acetylsalicylic acid (ASA (5 mg/kg and Warfarin (1 mg/daily. At three months’ follow-up, the aneurysms still persisted in the echocardiogram.

    The trigeminal artery is one of four primitive anastomoses between the internal carotid artery and vertebrobasilar system that regresses in the sixth week of fetal development. A persistent trigeminal artery (PTA) is generally an incidental finding but may also be associated with intracranial vascular pathologies such as aneurysms, arteriovenous malformations, and cranial nerve compression syndromes. We present an extremely rare case of a right PTA with an associated bleeding fusiform aneurysm located in the carotidian (lateral) part of the PTA. In addition, this rare anatomic variation was associated with bilateral absence of the posterior communicating arteries, a left posterior cerebral artery originating from the left internal carotid artery, and agenesis of the A1 segment of the left anterior cerebral artery.

  4. Carotid Stump Syndrome: Pathophysiology and Endovascular Treatment Options

    International Nuclear Information System (INIS)

    Carotid stump syndrome is one of the recognised causes of recurrent ipsilateral cerebrovascular events after occlusion of the internal carotid artery. It is believed that microemboli arising from the stump of the occluded internal carotid artery or the ipsilateral external carotid artery can pass into the middle cerebral artery circulation as a result of patent external carotid–internal carotid anastomotic channels. Different pathophysiologic causes of this syndrome and endovascular options for treatment are discussed.

    Full Text Available A 27-year old male presented with acute inferior wall myocardial infarction. Coronary angiogram revealed normal left coronary arteries and a giant coronary aneurysm in Right coronary artery (RCA. Primary angioplasty of RCA was performed. Large thrombus burden was retrieved with aspiration device and coronary flow restored. However, despite best efforts some thrombus remained and decision to stent was deferred to a later date. Dimensions of aneurysm on quantitative coronary angiogram were 16 mm in width and 43 mm in length. Two weeks later coronary angiogram revealed normal flow in RCA without any angiographically visible thrombus. PCI was performed with two 3.0 and times; 28 mm covered stents, graft master (JoStent deployed across the aneurysm, overlapping each other. This completely sealed the aneurysm and intravascular ultrasound confirmed no leakage through the covered stents. Patient remains asymptomatic 2 months post procedure on triple antiplatelet therapy.

O objetivo desta revisão sistemática foi descrever os resultados de estudos que investigaram a associação da SM com a doença arterial coronariana e doenças vasculares oclusivas. Foi realizada a revisão sistemática com dados de estudos originais publicados entre 1999 e 2008, escritos em inglês ou português, utilizando-se as bases de dados Medline, Pubmed, Highwire Press e Science Direct. Foram incluídos artigos que fizeram o diagnóstico da SM através do critério do National Cholesterol Education Program - Adult Treatment Panel III (NCEP ATP III, 2001. Foram excluídos estudos realizados com animais, de suplementação e que realizaram administração oral ou endovenosa de qualquer substância, assim como aqueles de baixa qualidade metodológica e com amostra inicialmente heterogênea. Apesar da heterogeneidade entre os estudos, observou-se que indivíduos com SM apresentam maior probabilidade (risco = 2,13 de desenvolverem as doenças vasculares oclusivas, doença coronariana, diabetes mellitus e acidente vascular encefálico. Mudanças no estilo de vida, como práticas alimentares saudáveis, atividade física regular e a cessação do tabagismo devem ser incentivadas pelos profissionais da saúde a fim de minimizar as complicações e a morbimortalidade associada à SM.

Despite the common association of NF1 with neurocutaneous features, its pathology can extend to numerous tissues not derived from the neural crest. Among the rare cerebrovascular abnormalities in NF1, more than 85% of cases are of purely occlusive or stenotic nature, with intracranial aneurysm being uncommon. Predominantly, the aneurysms are located in the internal carotid arteries (ICAs, being very rare bilateral aneurysms. This report describes a very unusual case of fusiform aneurysms of both ICAs in a Caucasian NF1 patient, with a new pathogenic intragenic heterozygous deletion of the NF1 gene, presenting at age 22 years with Tolosa–Hunt syndrome, because of partial thrombosis of the left giant intracavernous aneurysm. Medical treatment with anticoagulant therapy allowed a good outcome for the patient. In conclusion, early identification of cerebral arteriopathy in NF1 and close follow-up of its progression by neuroimaging may lead to early medical or surgical intervention and prevention of significant neurologic complications.Keywords: neurofibromatosis type 1, NF1 gene, multiplex ligation

  13. GLUT10 deficiency leads to oxidative stress and non-canonical αvβ3 integrin-mediated TGFβ signalling associated with extracellular matrix disarray in arterial tortuosity syndrome skin fibroblasts.

    2015-12-01

    Arterial tortuosity syndrome (ATS) is an autosomal recessive connective tissue disorder caused by loss-of-function mutations in SLC2A10, which encodes facilitative glucose transporter 10 (GLUT10). The role of GLUT10 in ATS pathogenesis remains an enigma, and the transported metabolite(s), i.e. glucose and/or dehydroascorbic acid, have not been clearly elucidated. To discern the molecular mechanisms underlying the ATS aetiology, we performed gene expression profiling and biochemical studies on skin fibroblasts. Transcriptome analyses revealed the dysregulation of several genes involved in TGFβ signalling and extracellular matrix (ECM) homeostasis as well as the perturbation of specific pathways that control both the cell energy balance and the oxidative stress response. Biochemical and functional studies showed a marked increase in ROS-induced lipid peroxidation sustained by altered PPARγ function, which contributes to the redox imbalance and the compensatory antioxidant activity of ALDH1A1. ATS fibroblasts also showed activation of a non-canonical TGFβ signalling due to TGFBRI disorganization, the upregulation of TGFBRII and connective tissue growth factor, and the activation of the αvβ3 integrin transduction pathway, which involves p125FAK, p60Src and p38 MAPK. Stable GLUT10 expression in patients' fibroblasts normalized redox homeostasis and PPARγ activity, rescued canonical TGFβ signalling and induced partial ECM re-organization. These data add new insights into the ATS dysregulated biological pathways and definition of the pathomechanisms involved in this disorder. PMID:26376865

    Full Text Available Superior mesenteric artery (SMA syndrome is a rare acquired disorder in which acute angulation of SMA causes compression of the third part of the duodenum between the SMA and the aorta, leading to obstruction. Loss of fatty tissue as a result of a variet y of debilitating conditions is believed to be the etiologic factor causing the acute angulation. Conditions like increased spinal lordosis, application of a body cast, short ligament of Treitz or unusually low origin of SMA may also precipitate this syndr ome. The diagnosis of SMA syndrome is based on clinical symptoms and radiologic evidence of obstruction. SMA syndrome has been described after rapid or severe weight loss in conditions such as cancer or extensive burn injuries, prolonged bed rest, anorexia , or malabsorption syndromes. Herewith we are reporting a case of post pancreatitis SMA syndrome. KEYWORDS: Post pancreatitis SMA syndrome; superior mesenteric artery syndrome; SMA syndrome.

    Spontaneous coronary artery dissection is an important etiology of nonatherosclerotic acute coronary syndrome, myocardial infarction, and sudden death. Innovations in the catheterization laboratory including optical coherence tomography and intravascular ultrasound have enhanced the ability to visualize intimal disruption and intramural hematoma associated with SCAD. Formerly considered "rare," these technological advances and heightened awareness suggest that SCAD is more prevalent than prior estimates. SCAD is associated with female sex, young age, extreme emotional stress, or extreme exertion, pregnancy, and fibromuscular dysplasia. The clinical characteristics and management strategies of SCAD patients are different than for atherosclerotic heart disease and deserve specific consideration. This review will highlight recent discoveries about SCAD as well as describe current efforts to elucidate remaining gaps in knowledge. PMID:27216840

    Ferro, J M

    2001-10-01

    Cognitive syndromes are common clinical manifestations of hyperacute stroke and may be the single or dominant presenting features. They are related to acute dysfunction of complex integrated distributed functional networks serving different cognitive domains. The most common cortical syndromes include nonfluent or fluent aphasia, neglect, collor agnosia, pure alexia and Balint's syndrome. Disturbances of declarative memory are common following posterior cerebral artery and thalamic strokes. Abulia can follow thalamic, caudate and capsular lesions. Intraventricular and subarachnoid haemorrhages can cause preeminent neuropsychological changes. Disorientation is present in about 40% of acute stroke patients and delirium complicates the course of 25% of acute strokes. Some hyperacute cognitive stroke syndromes are useful indicators of later disability. Cognitive syndromes may pose special difficulties to neurology residents, unless formal teaching in neuropsychology and psychiatry is included in their training programs. PMID:11697519

    This article reviews in detail the superficial brachiomedian artery (arteria brachiomediana superficialis), a very rare variant of the main arterial trunks of the upper limb. It branches either from the axillary artery or the brachial artery, descends superficially in the arm (similar to the course of the superficial brachial artery) and continues across the cubital fossa, runs superficially in the forearm, approaches the median nerve and enters the carpal canal to reach the hand. It usually terminates in the superficial palmar arch. The first drawing was published, in 1830, and the first description was published, in 1844. Altogether, to our knowledge, only 31 cases of a true, superficial brachiomedian artery have been reported (Some cases are incorrectly reported as superficial brachioradiomedian artery or superficial brachioulnomedian artery). Based on a meta-analysis of known, available studies, the incidence is 0.23% in Caucasians and 1.48% in Mongolians. Knowing whether or not this arterial variant is present is important in clinical medicine and relevant for: The catheterization via the radial or ulnar artery; harvesting the vascular pedicle for a forearm flap based on the radial, ulnar or superficial brachiomedian arteries; the possible collateral circulation in cases of the arterial closure; and the surgical management of carpal tunnel syndrome. Its presence can elevate the danger of an injury to the superficially located variant artery or of an accidental injection. PMID:27131025

    2016-01-01

    Background The cardiovascular consequences of obstructive sleep apnoea (OSA) differ by sex. We hypothesized that sex influences the severity of acute coronary syndrome (ACS) in patients with OSA. OSA was defined as an apnoea–hypopnoea index (AHI)>15 events·h-1. We evaluated the severity of ACS according to the ejection fraction, Killip class, number of diseased vessels, number of stents implanted and plasma peak troponin level. Methods We included 663 men (mean±SD, AHI 37±18 events·h-1) and 133 women (AHI 35±18 events·h-1) with OSA. Results The men were younger than the women (59±11 versus 66±11 years, p<0.0001), exhibited a higher neck circumference (p<0.0001), and were more likely to be smokers and alcohol users than women (p<0.0001, p = 0.0005, respectively). Body mass index and percentage of hypertensive patients or diabetics were similar between sexes. We observed a slight tendency for a higher Killip classification in women, although it was not statistically significant (p = 0.055). For men, we observed that the number of diseased vessels and the number of stents implanted were higher (p = 0.02, p = 0.001, respectively), and a decrease in the ejection fraction (p = 0.002). Conclusions This study shows that sex in OSA influences the severity of ACS. Men show a lower ejection fraction and an increased number of diseased vessels and number of stents implanted.

    We sought to determine the effectiveness of angiotensin-converting enzyme (ACE) inhibition and β-blocker treatment as a function of the degree of coronary artery disease (CAD) obstruction at angiography. The Evaluation of Methods and Management of Acute Coronary Events registry enrolled patients who had been hospitalized for an acute coronary syndrome. There were 1,602 patients who had cardiac catheterization that were used for this analysis. The main outcome measures were evidence-based therapies prescribed at discharge and 6-month incidence of all-cause mortality. The cohort consisted of 1,252 patients with obstructive CAD (>50% luminal diameter obstructed) and 350 patients with nonobstructive CAD. Multivariate logistic regression analysis adjusted for further medications and other clinical factors was performed. Patients with nonobstructive CAD had significantly (p <0.001) higher rates of β-blocker (77.8% vs 63.3%) and lower rates of ACE-inhibitor (57.7% vs 66.4%) prescriptions. In patients with nonobstructive CAD, ACE-inhibitor therapy was clearly associated with a lower 6-month mortality (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.03 to 0.78, p = 0.004). No significant association between β-blocker use and death was found. In patients with obstructive CAD, both β blockers (OR 0.47, 95% CI 0.32 to 0.67, p <0.001) and ACE inhibitors (OR 0.47, 95% CI 0.26 to 0.87, p = 0.01) were significantly associated with a reduced risk of 6-month mortality. In conclusion, ACE-inhibitor therapy seems to be an effective first-line treatment for preventing the occurrence of mortality in patients with nonobstructive CAD. PMID:24698468

    Introduction There is an evidence gap about how to best treat patients with prior coronary artery bypass grafts (CABGs) presenting with non-ST segment elevation acute coronary syndromes (NSTE-ACS) because historically, these patients were excluded from pivotal randomised trials. We aim to undertake a pilot trial of routine non-invasive management versus routine invasive management in patients with NSTE-ACS with prior CABG and optimal medical therapy during routine clinical care. Our trial is a proof-of-concept study for feasibility, safety, potential efficacy and health economic modelling. We hypothesise that a routine invasive approach in patients with NSTE-ACS with prior CABG is not superior to a non-invasive approach with optimal medical therapy. Methods and analysis 60 patients will be enrolled in a randomised clinical trial in 4 hospitals. A screening log will be prospectively completed. Patients not randomised due to lack of eligibility criteria and/or patient or physician preference and who give consent will be included in a registry. We will gather information about screening, enrolment, eligibility, randomisation, patient characteristics and adverse events (including post-discharge). The primary efficacy outcome is the composite of all-cause mortality, rehospitalisation for refractory ischaemia/angina, myocardial infarction and hospitalisation for heart failure. The primary safety outcome is the composite of bleeding, stroke, procedure-related myocardial infarction and worsening renal function. Health status will be assessed using EuroQol 5 Dimensions (EQ-5D) assessed at baseline and 6 monthly intervals, for at least 18 months. Trial registration number NCT01895751 (ClinicalTrials.gov).

    2009-07-01

    Full Text Available Abstract Patent arterial duct (PAD is a congenital heart abnormality defined as persistent patency in term infants older than three months. Isolated PAD is found in around 1 in 2000 full term infants. A higher prevalence is found in preterm infants, especially those with low birth weight. The female to male ratio is 2:1. Most patients are asymptomatic when the duct is small. With a moderate-to-large duct, a characteristic continuous heart murmur (loudest in the left upper chest or infraclavicular area is typical. The precordium may be hyperactive and peripheral pulses are bounding with a wide pulse pressure. Tachycardia, exertional dyspnoea, laboured breathing, fatigue or poor growth are common. Large shunts may lead to failure to thrive, recurrent infection of the upper respiratory tract and congestive heart failure. In the majority of cases of PAD there is no identifiable cause. Persistence of the duct is associated with chromosomal aberrations, asphyxia at birth, birth at high altitude and congenital rubella. Occasional cases are associated with specific genetic defects (trisomy 21 and 18, and the Rubinstein-Taybi and CHARGE syndromes. Familial occurrence of PAD is uncommon and the usual mechanism of inheritance is considered to be polygenic with a recurrence risk of 3%. Rare families with isolated PAD have been described in which the mode of inheritance appears to be dominant or recessive. Familial incidence of PAD has also been linked to Char syndrome, familial thoracic aortic aneurysm/dissection associated with patent arterial duct, and familial patent arterial duct and bicuspid aortic valve associated with hand abnormalities. Diagnosis is based on clinical examination and confirmed with transthoracic echocardiography. Assessment of ductal blood flow can be made using colour flow mapping and pulsed wave Doppler. Antenatal diagnosis is not possible, as PAD is a normal structure during antenatal life. Conditions with signs and symptoms of

    The association of persistent embryonic arteries and the absence of 1 carotid or vertebral arteries with facial or neck hemangioma or vascular malformation have been frequently described. The abnormalities can involve major or minor vessels. Of 22 patients of our series with this neurocutaneous syndrome, 20 had the origin of both anterior cerebral arteries from the same internal carotid artery. Thirteen patients showed absence or hypoplasia of 1 carotid artery and 10 of 1 vertebral artery; 10 showed persistence of the trigeminal artery; 3 had persistent proatlantal artery; 6 showed the absence of the posterior communicating artery; and 4 had hypoplastic posterior cerebral artery. Other less frequent abnormalities were found in 7 patients. Intellectual level of most patients was either borderline or below normal. Abnormalities in the vascularization and perfusion of the frontal lobes may contribute to the borderline or lower mental level of these patients. PMID:19808986

    Hepatopulmonary syndrome (HPS) is defined by the association of portal hypertension, increased alveolar-arterial oxygen gradient and intrapulmonary vascular dilations. Pathophysiological mechanisms of hypoxemia are characterized by ventilation-perfusion mismatch, oxygen diffusion limitation between alveolus and the centre of the dilated capillary, and right-to-left shunting. An excess of vasodilator molecules (like nitric monoxide) and proangiogenic factors (like VEGF) play an important role in the occurrence of HPS. Symptoms of HPS are not specific and dominated by a progressive dyspnea in upright position. Pulse oximetry is a simple non-invasive screening test but only detect the most severe forms of HPS. Medical treatment is disappointing and only liver transplantation may lead to resolution of HPS. Survival following liver transplantation is promising when hypoxemia is not severely decreased.

    Chromosomal abnormalities as well as non-cardiac anomalies have been identified as independent risk factors for surgical morbidity and mortality in Fontan palliation. The combination of malformations consisting of pulmonary hypoplasia, agonadism (sex reversal), omphalocele, and diaphragmatic defect is compatible with pulmonary artery and lung hypoplasia, agonadism, omphalocele, and diaphragmatic defect (PAGOD). Most cases have been associated with cardiac disease, particularly hypoplastic left heart syndrome (HLHS) that is potentially destined for Fontan palliation. Reported herein is the case of a Japanese female infant diagnosed with PAGOD syndrome along with HLHS (mitral atresia and aortic atresia), in whom intractable respiratory failure manifested as bilateral eventration of the diaphragm and presumed right lung hypoplasia. These characteristic pulmonary lesions associated with the syndrome precluded use of the Fontan pathway. PMID:24894929

    stroke and clinical symptoms checked with TCD and CDFI.RESULTS: A total of 159 patients with ischemic stroke were involved in the final analysis; in addition, 112 oases received cerebrovascular imaging examination simultaneously. ① MRI results of 159 patients with cerebral artery occlusive disease (CAOD): There were 131 patients (82.3%) with cerebral infarction, 40 (25.2%)with transient ischemic attack and 4 (2.5%) with subclavian steal syndrome (SSS). ② Infarction types with MRI examination: There were 33 patients (20.8%) with solitary cerebral infarction and 98 (61.6%) with multiple-cerebral infarction. ③ Results of TCD, CDFI, MRI angiography, CT angiography and digital subtraction angiography (DSA): Among 112 patients, 181 lesion sites (61 .8%) were located in cranium and 112 lesion sites were located out of cranium; especially, lesion site was mostly observed in stem of middle cerebral artery (31.2%) and watershed of basilar artery (7.2%) in cranium and the beginning site of internal carotid artery (21 .4%) out of cranium. ④ Correlation of vascular stricture checking with TCD, MRI and clinical diagnosis: On one hand, MRI and clinical diagnosis demonstrated that 68 patients had a watershed infarction; meanwhile,TCD examination indicated that there were 3 patients with mild vascular stricture, 24 with moderate vascular stricture and 36 with severe vascular stricture. On the other hand, among 68 patients with non-watershed infarction, there were 27 patient with mild vascular stricture, 26 with moderate vascular stricture and 15 with severe vascular stricture. There were significant differences (x2 =26.854, P =0.001 ). Clinical diagnosis indicated that 40 patients had transient ischemic attack and TCD examination demonstrated that there were 8 patient with mild vascular stricture, 12 with moderate vascular stricture and 20 with severe vascular stricture. There were significant differences as compared with 68 patients with watershed infarction (x2 =21.258, P =0

    In Robocop Keepaway training task,traditional hand-coded ball-stealing strategies are very subjective and can't adapt well to training situation changes,this leads to the takers taking longer time to complete the tasks and having lower stealing success rate.To solve this problem,we apply the reinforcement learning to high-level action decision-making for stealing takers in Keepaway task.By analysing the characteristic of stealing task,we reasonably design the state space,action space and reward value of the reinforcement learning model of stealing takers,and state a corresponding reinforcement learning algorithm for stealing takers.Experimental results show that after the rein-forced learning the stealing takers can make more objective decisions according to game's situation,the effect of the decisions made are re-markably better than the hand-coded strategies.For typical 4v3 and 5v4 scale Keepaway tasks,with the learned strategy to making decision, the stealing takers shorten 7.1% of the time at least for completing ball -stealing task,and the stealing success rate increases no less than 15.0% as well.%在 RoboCup Keepaway 任务训练中,传统手工抢球策略的主观性强,对训练情形变化的适应性差,导致抢球球员任务完成时间长、抢断成功率低。针对这一问题,将强化学习应用于 Keepaway 中抢球球员的高层动作决策。通过对抢球任务特点的分析,合理设计了抢球球员强化学习模型的状态空间、动作空间及回报值,并给出了抢球球员的强化学习算法。实验结果表明经强化学习后,抢球球员能够根据比赛情形做出更客观的决策,决策效果显著优于手工策略。对于4v3和5v4规模的典型 Keepaway 任务,抢球球员采用学习后的策略决策时,抢球任务完成时间至少缩短了7.1%,抢断成功率至少提升了15.0%。

    Full Text Available A mobile thrombus in the carotid arteries is a very rare ultrasonographic finding and is usually diagnosed after a neurological emergency, such as a transient ischemic attack or cerebral infarction. We present the case of a 54-year-old man with vascular risk factors (a heavy smoker, untreated hypertension who was admitted to the emergency unit with right sided hemiparesis and aphasia. A cerebral CT scan showed a left middle cerebral artery territory infarction. The duplex ultrasound examination revealed mild atherosclerotic changes in the right common and internal carotid arteries, right-sided complete subclavian steal phenomenon and a complicated hypoechoic atherosclerotic plaque in the left common carotid artery with a large mobile thrombus. Due to the high embolization risk, the patient was hospitalised and prescribed Aspirin together with low molecular weight Heparin. We recorded an improvement in the patient’s neurological status and the control duplex scan revealed disappearance of the thrombus. The presence of floating thrombus in a patient with clinical and imagistic evidence of stroke is a major therapheutic challenge for the neurologist. The treatment strategies are not standardized and must be individualized, however in our case parenteral anticoagulation proved to be successful.

    2012-01-01

    Hepatorenal syndrome (HRS) is defined as a functional renal failure in patients with liver disease with portal hypertension and it constitutes the climax of systemic circulatory changes associated with portal hypertension.This term refers to a precisely specified syndrome featuring in particular morphologically intact kidneys,where regulatory mechanisms have minimised glomerular filtration and maximised tubular resorption and urine concentration,which ultimately results in uraemia.The syndrome occurs almost exclusively in patients with ascites.Type 1 HRS develops as a consequence of a severe reduction of effective circulating volume due to both an extreme splanchnic arterial vasodilatation and a reduction of cardiac output.Type 2 HRS is characterised by a stable or slowly progressive renal failure so that its main clinical consequence is not acute renal failure,but refractory ascites,and its impact on prognosis is less negative.Liver transplantation is the most appropriate therapeutic method,nevertheless,only a few patients can receive it.The most suitable "bridge treatments" or treatment for patients ineligible for a liver transplant include terlipressin plus albumin.Terlipressin is at an initial dose of 0.5-1 mg every 4 h by intravenous bolus to 3 mg every 4 h in cases when there is no response.Renal function recovery can be achieved in less than 50% of patients and a considerable decrease in renal function may reoccur even in patients who have been responding to therapy over the short term.Transjugular intrahepatic portosystemic shunt plays only a marginal role in the treatment of HRS.

    Full Text Available Introduction. Streptococcal toxic shock syndrome is now recognized as a toxin-mediated, multisystem illness. It is characterized by an early onset of shock with multiorgan failure and continues to be associated with high morbidity and mortality, caused by group A Streptococcus pyogenes. The symptoms for staphylococcal and streptococcal toxic shock syndrome are similar. Streptococcal toxic shock syndrome was not well described until 1993, when children who had suffered from varicella presented roughly 2-4 weeks later with a clinical syndrome highly suggestive of toxic shock syndrome. Characteristics, complications and therapy. It is characterized by a sudden onset of fever, chills, vomiting, diarrhea, muscle aches and rash. It can rapidly progress to severe and intractable hypotension and multisystem dysfunction. Almost every organ system can be involved. Complications of streptococcal toxic shock syndrome may include kidney failure, liver failure and even death. Crystalloids and inotropic agents are used to treat the hypovolemic shock aggressively, with close monitoring of the patient’s mean arterial pressure and central venous pressure. An immediate and aggressive management of hypovolemic shock is essential in streptococcal toxic shock syndrome. Targeted antibiotics are indicated; penicillin or a betalactam antibiotic is used for treating group A streptococci, and clindamycin has emerged as a key portion of the standard treatment.

    Abstract Preoperative medication by inhibitors of angiotensin-converting enzyme (ACE) in coronary artery patients predisposes to vasoplegic shock early after coronary artery bypass grafting. Although in the majority of the cases this shock is mild, in some of them it appears as a situation, "intractable" to high-catecholamine dose medication. In this study we examined the possible role of prophylactic infusion of low-dose vasopressin, during and for the four hours post-bypass after cardiopulm...

  7. Impact of metabolic syndrome and diabetes mellitus on cardiovascular events in coronary artery disease without ischemia on stress thallium-201 single photon emission computed tomography after percutaneous coronary intervention

    International Nuclear Information System (INIS)

    The metabolic syndrome defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) is a predictor of cardiovascular events. However, the significance of metabolic syndrome for cardiovascular events has been not clarified in Japan. The impact of metabolic syndrome and diabetes mellitus on cardiovascular events was investigated, especially in the high risk group after percutaneous coronary intervention. We studied 456 patients (mean age 63±10 years, range 36-88 years) without ischemia on stress thallium-201 single photon emission computed tomography after percutaneous coronary intervention. The diagnosis of metabolic syndrome was made according to the modified NCEP ATP III criteria. Cardiovascular events were examined for mean 3.7±1.8 years (range 2.0-8.7 years). There were 196 patients without diabetes mellitus or metabolic syndrome (Group D-M-), 89 patients without diabetes mellitus but with metabolic syndrome (Group D-M+), 61 patients with diabetes mellitus but without metabolic syndrome (Group D+M-), and 110 patients with both diabetes mellitus and metabolic syndrome (Group D+M+). The event-free survival curve in Group D-M+ was significantly lower than that in Group D-M- (p<0.05), but not different from that in Group D+M-. The survival curve was markedly lower in Group D+M+ than that in Group D-M+ (p<0.005). The Cox proportional hazard model revealed that diabetes mellitus and metabolic syndrome were independent significant risk factors for events. The diagnosis of metabolic syndrome was helpful for identification of patients with high cardiovascular event rate even in patients after percutaneous coronary intervention. The combination of metabolic syndrome and diabetes mellitus markedly increases the risk for cardiovascular events. (author)

    Cervical artery dissection (CAD) represents an increasingly recognized cause of stroke and the most common cause of ischemic stroke in young adults. Many factors have been identified in association with CAD such as primary disease of arterial wall (fibrodysplasia) and other non-specific diseases related to CAD like Ehlers Danlos-syndrome IV, Marfan's syndrome, vessel tortuosity. Moreover, an underlying arteriopathy which could be in part genetically determined, has been suspected. The rule of emerging risk factors for CAD such as recent respiratory tract infection, migraine and hyperhomocysteinemia are still a matter of research. Other known risks factors for CAD are major head/neck trauma like chiropractic maneuver, coughing or hyperextension injury associated to car. We examined emerging risks factors for CAD detected in the last years, as CAD pathogenesis is still not completely understood and needs further investigations. PMID:21270941

    Williams-Beuren syndrome is a rare familial multisystem disorder occurring in 1 per 20,000 live births. It is characterized by congenital heart defects (CHD), skeletal and renal anomalies, cognitive disorder, social personality disorder and dysmorphic facies. We present a case of Williams syndrome that presented to us with heart murmur and cognitive problem. A 5-year-old girl referred to pediatric cardiologist because of heart murmurs. She had a systolic murmur (2-3/6) in right upper sternal border with radiation to right cervical region. She also had a bulge forehead. Angiography showed mild supra valvular aortic stenosis and mild multiple peripheral pulmonary stenosis. Fluorescent in situ hybridization (FISH) was performed and the result was: 46.XX, ish del (7q11.2) (ELN X1) (7q22 X2) ELN deletion compatible with Williams syndrome. Peripheral pulmonary artery stenosis is associated with Noonan syndrome, Alagille syndrome, Cutis laxa, Ehler-Danlos syndrome, and Silver-Russel syndrome. The patient had peripheral pulmonary artery stenosis, but no other signs of these syndromes were present, and also she had a supravalvular aortic stenosis which was not seen in other syndromes except Williams syndrome. Conclusion. According to primary symptoms, paraclinical and clinical finding such as dysmorphic facies, cognitive disorder and congenital heart defect, Williams syndrome was the first diagnosis. We suggest a more attention for evaluating heart murmur in childhood period, especially when the patient has abnormal facial features or mental problem. PMID:22927862

  13. Catastrophic antiphospholipid Syndrome

    International Nuclear Information System (INIS)

    The antiphospholipid syndrome (APS) is characterized by venous, arterial thrombosis and miscarriages along with lupic anticoagulant and antibodies against anticardiolipin. The catastrophic antiphospholipid syndrome (CAPS) has been described since 1992 like a multiple organic dysfunction caused by multiple vascular thrombosis in three or more organs. The patients who suffer from this syndrome may have or not history of APS. There are two or three mechanisms that may cause the CAPS, alone or in combination: These are: 1. The multisystemic thrombotic disease with emphasis in microvasculature occlusion of the organs and occlusion of big arterial or veins 2. The disseminated intravascular coagulation (DIC) superimpose in 15% to 50% of the patients that, of course, conducted to an occlusive disease of arterioles, veins or capillaries. 3. A systemic inflammatory response syndrome (SIRS) induced by citoquines. In this review it is described clinical and laboratory features, pathogenesis and treatment of CAPS. For this purpose, it was searched for Medline from 1993 to 2000 and revised the most significant issues obtained by this medium

    Objective: To determine the frequency of metabolic syndrome in male patients presenting with acute coronary syndrome Study design: A Descriptive study Place and duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008 Patients and Methods: Male patients with acute coronary syndrome (ACS) were included. Patients having angioplasty (PCI), coronary artery bypass surgery in the past and other co-morbid diseases were excluded. All patients were assessed for the presence of five components of metabolic syndrome including hypertension, HDL-Cholesterol and triglycerides, glucose intolerance and abdominal obesity. Systolic, diastolic blood pressures, waist circumference (WC) and body mass index (BMI) were measured. ECG, cardiac enzymes, fasting glucose and lipid profile were also done. Results: A total of 135 male patients of ACS were studied with a mean age of 54.26 +- 11 years. Metabolic syndrome (MS) was present in 55 (40.7%) patients. MS with all five components was documented in 4 (7.27%) while MS with four and three components was seen in 23 (41.81%) and 28 (50.90%) patients respectively. Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

  15. [Vascular Ehlers-Danlos syndrome].

    2009-04-20

    Vascular type Ehlers-Danlos syndrome (EDS) is a rare inherited disease with an autosomal dominant trait. The mutation of the COL3A1 gene which encodes type III collagen, is responsible of early vascular (spontaneous arterial rupture or dissection), digestive (perforation) and obstetrical events (uterine and arterial rupture). Diagnosis of the disease is primarily clinical, especially in case of characteristic morphologic features. Diagnostic certainty is obtained by evidencing the mutation of the COL3A1 gene. Some arterial lesions are suggestive of the disease, as dissecting aneurysms of the internal carotid, of the iliac arteries, and of the anterior visceral aortic branches, fusiform aneurisms of the splenic artery, and the occurrence of a non traumatic direct carotid-cavernous fistula. The occurrence of a spontaneous peritonitis or of an extensive perineal tear after delivery should also draw physician's attention. Because of the unpredictability of arterial or organ rupture, any patient diagnosed with vascular type EDS presenting with an acute pain syndrome should be considered as a trauma situation and be investigated straightaway by CT-scan or MRI testing, in order to eliminate a life threatening complication.

    Background The blood supply to the eye comes from the retinal central vascular system of the ophthalmic artery and the ciliary vascular system. The ophthalmic artery stems from the ipsilateral internal carotid artery. If occlusion or stenosis occurs in the carotid artery, the blood perfusion to the ophthalmic artery becomes insufficient, leading to signs and symptoms of anterior and posterior ocular ischemia. The objective of this study was to evaluate the clinical characteristics and risk factors of ocular ischemic diseases caused by carotid artery stenosis.Methods This study was a retrospective review of 145 patients with carotid artery stenosis. Fifty-eight patients who had symptoms of ocular ischemic disease caused by carotid artery stenosis formed group A and the other 87 patients who only had carotid artery stenosis formed group B. We analyzed the causes and course of disease, and relative risk factors,by comparing the two groups.Results The degree of carotid artery stenosis in group A was higher than that in group B. And group A had a greater decrease of ophthalmic artery flow. Male, hypertension, hyperlipidemia, and smoking were significantly related to carotid artery stenosis. Amaurosis fugax was the most common ocular symptom in group A. The ocular ischemic diseases mainly included ischemic optic neuropathy, central/branch retinal artery occlusion, ophthalmoplegia externa, and ocular ischemic syndrome.Conclusions Carotid artery stenosis correlates with ocular ischemic diseases. Ophthalmologists must observe for ocular symptoms, which were the onset symptoms in some patients.

    Full Text Available Background: The hepatic arterial anatomy is aberrant in almost 33-41% of individuals. The variant arterial anatomy recognized during routine cadaveric dissection offers great learning potential. Such findings provide an alternative perspective to view common morphology and its structural and functional importance. These impart the concept of patient individuality and subsequent individualization of medical and surgical therapies. Adequate knowledge of normal and abnormal arterial anatomy is essential for peripancreatic surgery and liver transplantation. Aims of the study: To report on hepatic artery variations observed in the dissecting room and to find out the macroscopic pattern of varied human hepatic arterial vascularization by cadaveric dissection. Patients and Methods: Twenty human cadavers of caucasian origin were dissected to study the source and topographic pattern of hepatic arterial supply. Results: Nineteen cadavers exhibited typical hepatic arterial supply from the celiac axis. Only one female body out of twenty cadavers exhibited a dual arterial supply to all parts of liver and gallbladder. One artery originated from the celiac axis whereas the other was given off by the superior mesenteric artery. Conclusion: No doubt, aberrant hepatic vascularization should be assessed preoperatively by invasive and noninvasive techniques to avoid fatal complications, but we favour careful dissection over angiography as a means of defining the arterial anatomy.

    Full Text Available Renal failure is a common major complication in patients with advanced cirrhosis and generally indicates a poor prognosis when combined with liver failure. Hepatorenal syndrome (HRS is characterised by a combination of disturbances in circulatory and kidney function. Arterial pressure is decreased in the systemic circulation due to reduced total systemic vascular resistance. Kidney dysfunction is caused by reduction in renal blood flow. The diagnosis of HRS is based on exclusion of other disorders that cause acute kidney injury in cirrhosis as there are no specific tests. There are two types of HRS with different characteristics and prognostics. Liver transplantation is the treatment of choice for all patients without contraindication. The best approach to the pharmacologic management is the administration vasoconstrictor drugs based on the pathogenesis. Many vasoconstrictors including vasopressin analogues (terlipressin, ornipressin and vasopressin, somatostatin analogues (octreotide and alpha-adrenergic analogues (midodrine and norepinephrine have been studied. In most of the studies intravenous albumin therapy was coadministered with vasoconstrictor drugs and suggested that albumin should be considered as the component of pharmacologic intervention in patients with HRS. Renal replacement therapy in the form of hemodialysis or continuous venovenous hemofiltration has been used in the management of HRS patients awaiting transplantation or in those with acute potentially reversible conditions. The artificial hepatic support systems require further investigation. (Journal of the Turkish Society Intensive Care 2012; 10: 37-44

One week prior, she had undergone a Cesarean delivery which was complicated by hemolysis, elevated liver enzymes, and low platelet count syndrome (HELLP), fetal dystocia, and chorioamnionitis. Uterine dilatation and curettage (D & C) and placement of a Bakri intrauterine balloon, performed for suspected retained products of conception, failed to control her postpartum bleeding. The patient wished to have a hysterectomy only as a last resort in order to preserve fertility. Emergency uterine artery angiography revealed a left uterine artery pseudoaneurysm and contrast extravasation. The patient was successfully treated with selective embolization. Computed tomography (CT) later revealed dehiscence of her uterine Cesarean section incision with an intra-abdominal fluid collection. This collection was drained. She also developed disseminated intravascular coagulopathy (DIC) syndrome as well as multiple pulmonary emboli which were both successfully treated. We discuss this unique case of uterine artery pseudoaneurysm with associated uterine dehiscence. PMID:22606544

    Hepatopulmonary syndrome (HPS) is a pulmonary complication of liver disease characterized by arterial hypoxemia. Mechanisms related to this event are diffusion-perfusion flaw, ventilation-perfusion (V/Q) mismatch, and direct arteriovenous shunts. Diagnosis of HPS is based on the presence of liver disease or portal hypertension, increased alveolar-arterial (A-a) PO2, and intrapulmonary vascular dilatations (IPVD). Lung transplantation (LT) remains the most effective therapy for HPS. In spite of its poor prognosis, we could improve the quality of life and survival rate of patients. PMID:27352437

    Objective To investigate the association between vascular endothelial functions and pathological change degree of coronary arteries in patients with acute coronary syndrome(ACS). Methods We enrolled 43 patients who were diagnosed with ACS by coronary angiography (ACS group) and 30 non-coronary heart disease patients as controls (control group) into this study. The number of coronary branches and Gensini score were used to evaluate the pathological change degree of coronary artery in the patient with ACS. Flow mediated dilatation of the brachial artery ( FMD) were measured to evaluate the vascular endothelial functions. Results FMD was significantly reduced in ACS group compared with that in control group (P < 0.05 ). There was a negative association between impaired FMD and Gensini score in ACS group. Conclusion FMD was significantly reduced in the patients with ACS. There was a negative association between increased pathological change degree of coronary artery and impaired FMD in the patients with ACS. The present study suggested that the measurement of FMD might be used as a novel index for the determination of the pathological.%目的 探讨急性冠脉综合征(ACS)病人血管内皮功能与冠状动脉病变严重程度的关系.方法 选取经冠状动脉造影确诊的ACS病人43例,以冠脉病变支数和Gensini评分来评价冠脉病变严重程度,同时以我院门诊非冠心病患者30例作为对照组.采用流量介导的肱动脉扩张(FMD)测定来评估血管内皮功能.结果 ACS组FMD水平明显低于对照组(P<0.05),ACS组FMD水平与Gensini评分呈负相关.结论 ACS患者FMD水平明显降低,且FMD水平与冠状动脉病变严重性呈负相关,可作为ACS患者冠状动脉病变严重程度的预测指标.

    This paper describes an automutilation syndrome (OAS) in three species of captive octopuses, Octopus dolfleini, O. bimaculoides, and O. maya, characterized by external arm and mantle lesions. Three clinical patterns in nine animals had similar and characteristic gross and histopathologic features. Axial nerve or brachial artery lesions were observed in six of the nine cases and vascular lesions were seen in two of eight cases with mantle ulcerations. A relationship between automutilation in the octopus and dysesthesias due to neural or vascular pathology is proposed. PMID:2351844

Inverted and bulbous tips of fingers were noted at age 9 and protruded occipital bone at age 10. He complained of left facial spasm and facial tics for 1 year. Examination revealed a man of short stature, with a brachycephalic skull and hypertelorism. Radiologically there was an extreme degree of basilar impression with the basal angle of 180 degrees, demineralized spinal vertebrae, and acro-osteolysis. Both bone and CT scans demonstrated the abnormalities of the skull clearly. The basilar artery ran almost horizontally on angiography. He gradually deteriorated neurologically with bulbar, pyramidal and cerebellar signs and symptoms. Review of the literature revealed at least then non-familial and nine familial cases of this disorder. It is considered that this syndrome is a genetically determined generalized dysplastic bone disorder. (orig.)

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    @@ Takotsubo syndrome (transient left ventricular apical ballooning syndrome) is a novel cardiac syndrome of left ventricular apical ballooning involving reversible left ventricular apical ballooning (during systole) of acute onset with chest pain, electrocardiographic changes, and minimal elevation of cardiac enzymes resembling acute myocardial infarction, but without evidence of myocardial ischemia or injury. Patients have no angiographic evidence of coronary artery stenosis and there is almost always a complete recovery of left ventricular function in days to weeks. The precise etiologic basic of this syndrome is not clear but most likely it is a non-ischemic, metabolic syndrome caused by stress-induced activation of the cardiac adrenoceptors in absence of ischemia and reperfusion.1-3 Reported here is a case of stress-induced transient left ventricular apical ballooning syndrome in an elderly Chinese woman.

    A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery. PMID:21106320

  13. Aphasia following anterior cerebral artery occlusion

    International Nuclear Information System (INIS)

    We have report two cases of aphasia that had infarcts in the distribution of the left or right anterior cerebral artery, as confirmed by computed tomography. Case 1 is a right-handed, 65-year-old man in whom computerized tomographic scanning revealed an infarction of the territory of the left anterior cerebral artery after the clipping of the anterior communicating artery aneurysm. The standard language test of aphasia (SLTA) revealed non-fluent aphasia with dysarthria, good comprehension, almost normal repetition with good articulation, and a defectiveness in writing. This syndrome was considered an instance of transcortical motor aphasia. Although three years had passed from the onset, his aphasia did not show any improvement. Case 2 is a 37-year-old man who is right-handed but who can use his left hand as well. He was admitted because of subarachnoid hemorrhage from an anterior communicating aneurysm. Because of postoperative spasm, an infarction in the distribution of the right anterior cerebral artery developed. He was totally unable to express himself vocally, but he could use written language quite well to express his ideas and had a good comprehension of spoken language. This clinical picture was considered that of an aphemia. After several weeks, his vocalization returned, but the initial output was still hypophonic. (J.P.N.)

    Full Text Available FUNDAMENTO: A Hipertensão arterial (HA é uma condição tanto agravante quanto agravada pela Síndrome Metabólica (SM. A menopausa pode tornar o tratamento da hipertensão mais difícil porque é uma condição que favorece a piora nos componentes da SM. Embora existam evidências de que o treinamento com exercícios físicos reduza a pressão arterial, se as condições da menopausa e da SM afetam os benefícios induzidos pelo exercício é algo ainda não evidenciado. OBJETIVO: Comparar os efeitos do treinamento aeróbio na pressão arterial entre mulheres com SM não menopausadas e menopausadas. MÉTODOS: Foram recrutadas 44 mulheres divididas em quatro grupos experimentais: controle não menopausada (CNM: 39,5 ± 1,1 anos, n = 11; controle menopausada (CM: 54,9 ± 1,7 anos, n = 12; aeróbio não menopausada (ANM: 43,1 ± 2,1 anos, n = 11 e aeróbio menopausada (AM: 52,1 ± 1,6 anos, n = 10. Os grupos de exercício realizaram treinamento aeróbio durante três meses, cinco vezes por semana, com intensidade entre 60% e 70% da frequência cardíaca de reserva. A pressão arterial de repouso e a resposta pressórica clínica após 60 minutos de exercício foram medidas antes e após o período treinamento. O teste de ANOVA de dois fatores foi usado, considerando p 0,05. CONCLUSÃO: Três meses de treinamento aeróbio melhora componentes da SM, mas não altera a pressão arterial de repouso, nem a resposta pressórica aguda após uma sessão de exercício aeróbio em mulheres com SM.BACKGROUND: Arterial Hypertension (AH is an aggravating condition for Metabolic Syndrome (MS, as well as being aggravated by it. Menopause can make hypertension treatment more difficult, as it favors the worsening of MS components.

    Full Text Available Antiphospholipid syndrome is characterized by the presence of antiphospholipid antibodies with characteristic clinical manifestation, which include venous, arterial thrombosis, thrombotic microangiopathy, and recurrent fetal loss. The syndrome can be secondary to many causes including systemic lupus erythematosus (SLE or "primary" antiphospholipid syndrome (APLS. We report a case of a man with catastrophic antiphospholipid syndrome (CAPS, which occurs when three or more organ systems are affected by thrombosis in less than a week. Catastrophic antiphospholipid syndrome is uncommon but often fatal. The patient received a successful treatment that controlled this disease and included intravenous heparin, antiplatelet, intravenous corticosteroid, and plasmapheresis.

  17. Spinal cord ischemia: aetiology, clinical syndromes and imaging features

    International Nuclear Information System (INIS)

    The purpose of this study was to analyse MR imaging features and lesion patterns as defined by compromised vascular territories, correlating them to different clinical syndromes and aetiological aspects. In a 19.8-year period, clinical records and magnetic resonance imaging (MRI) features of 55 consecutive patients suffering from spinal cord ischemia were evaluated. Aetiologies of infarcts were arteriosclerosis of the aorta and vertebral arteries (23.6 %), aortic surgery or interventional aneurysm repair (11 %) and aortic and vertebral artery dissection (11 %), and in 23.6 %, aetiology remained unclear. Infarcts occurred in 38.2 % at the cervical and thoracic level, respectively, and 49 % of patients suffered from centromedullar syndrome caused by anterior spinal artery ischemia. MRI disclosed hyperintense pencil-like lesion pattern on T2WI in 98.2 %, cord swelling in 40 %, enhancement on post-contrast T1WI in 42.9 % and always hyperintense signal on diffusion-weighted imaging (DWI) when acquired. The most common clinical feature in spinal cord ischemia is a centromedullar syndrome, and in contrast to anterior spinal artery ischemia, infarcts in the posterior spinal artery territory are rare. The exclusively cervical location of the spinal sulcal artery syndrome seems to be a likely consequence of anterior spinal artery duplication which is observed preferentially here. (orig.)

    Our population is ageing. The prevalence of dementia is increasing as the population ages. Dementia is known to share many common risk factors with coronary artery disease including age, genetics, smoking, the components of the metabolic syndrome and inflammation. Despite the growing ageing population with dementia, there is underutilization of optimal care (pharmacotherapy and interventional procedures) in this cohort. Given common risk factors and potential benefit, patients with cognitive impairment and dementia should be offered contemporary care.

    Full Text Available Abstract Objective Behcet's is an idiopathic multi-organ syndrome, which may have onset during childhood. Vascular involvement is uncommon, with rarely reported coronary aneurysm formation. We present a case report of a teenager girl who developed recalcitrant life-threatening Behcet's vasculitis, involving both small and large venous and arterial systems including a giant coronary aneurysm. Case report De-identified data were collected retrospectively in case report format. Although our sixteen year old female with Behcet's vasculitis had resolution of many arterial aneurysms, she had persistent venous thrombosis of large vessels, as well as persistent, giant arterial aneurysms requiring intra-arterial coiling of a lumbar artery and coronary bypass grafting despite intensive immunosuppression including glucocorticoids, cyclophosphamide, infliximab, methotrexate, azathioprine and intravenous immunoglobulin. Conclusions Vascular manifestations may be seen in Behcet's syndrome, including asymptomatic coronary aneurysm, which may be refractory to immunosuppression and ultimately require surgical intervention. Increased awareness is essential for prompt diagnosis and management.

    Pseudoaminopterin syndrome or aminopterin syndrome-like sine aminopterin (ASSA syndrome--OMIM 600325] is a rare autosomal recessive syndrome defined by characteristic dysmorphic features, skeletal defects, limb anomalies, cryptorchidism, and growth retardation. The syndrome owes its name to the fact that patients resemble the children exposed to aminopterin or to methotrexate, two dihydrofolate reductase inhibitors used for chemotherapy, or as an abortificient in early pregnancy. Ten patients have been described with pseudoaminopterin syndrome. Their phenotype is variable, and differs from the phenotype resulting from folic acid deprivation, leading to the notion that the pathogenesis may be more complex than simple vitamin deficiency. We report on an Algerian patient with pseudoaminopterin syndrome, review the previously reported cases and confirm that pseudoaminopterin syndrome does not result from a detectable contiguous gene imbalance as high resolution CGH array was normal in this child.

    Alagille syndrome (OMIM 118450) is an autosomal dominant disorder associated with abnormalities of the liver, heart, eye, skeleton, and a characteristic facial appearance. Also referred to as the Alagille-Watson syndrome, syndromic bile duct paucity, and arteriohepatic dysplasia, it is a significant cause of neonatal jaundice and cholestasis in older children. In the fully expressed syndrome, affected subjects have intrahepatic bile duct paucity and cholestasis, in conjunction with cardiac ma...

  17. PERIPHERAL ARTERIAL DISEASE IN THE LEG

    Full Text Available INTRODUCTION: Peripheral arterial disease (PAD is a condition characterized by atherosclerotic occlusive disease of the lower extremities. While PAD is a major risk factor for lower-extremity amputation, it is also accompanied by a high likelihood for symptomatic cardiovascular and cerebrovascular disease. Atherosclerosis accounts for more than 90% of cases of PAD, and uncommon vascular syndromes account for the remaining 10%. The femoral and popliteal arteries are affected in 80% to 90% of symptomatic PAD patients, the tibial and peroneal arteries in 40% to 50%, and the aortoiliac arteries in 30%.Although 65–75% of patients with PAD are asymptomatic, the classic presenting symptom is usually described as muscle cramps, fatigue or pain in the lower legs induced by exercise and rapidly relieved by rest; often the symptom location indicates the level of arterial involvement. RISK FACTORS: Diabetes and smoking are the strongest risk factors for PAD. Other well-known risk factors are advanced age, hypertension, and hyperlipidemia. DIAGNOSIS: PAD can be easily and accurately diagnosed by calculating the ankle-brachial index (ABI.The ABI is defined as the ratio of the systolic blood pressure in the ankle divided by the systolic blood pressure at the arm. The tools required to perform the ABI measurement include a hand-held 5–10 MHz Doppler probe and a blood pressure cuff. MANAGEMENT: Most patients' symptoms improve with optimal medical treatment and invasive intervention is often not required. Smoking cessation and exercise are considered the two most important treatments for PAD. CONCLUSION: Symptomatic PAD often impairs a patient's quality of life and untreated disease can lead to limb loss. Aggressive management of atherosclerotic risk factors, a structured exercise program, use of antiplatelet agents and when indicated percutaneous or surgical revascularizations are the keys for successful management.

    Bland-White-Garland syndrome is a rare syndrome with anomalous origin of the left coronary artery (LCA) arising from the pulmonary artery, resulting in left ventricular failure. It could occur shortly after birth. We here reported the case of a 6-week-old boy with aortostenosis. Coronary angiography revealed an anomalous LCA arising from the pulmonary artery. Representation of a prominent right coronary artery (RCA) delivered numerous collateral vessels to the LCA area. The patient underwent a correction operation with translocation of the LCA and re-implantation into the ascending aorta. One month after operation, clear decrease in the expanded ventricle was noted with an increase in the contractibility.

  5. Hepatopulmonary syndrome: an update.

    Macêdo, Liana Gonçalves de; Lopes, Edmundo Pessoa de Almeida

    2009-07-01

    Hepatopulmonary syndrome (HPS) is a clinical threesome composed of liver disease, intrapulmonary vascular dilatation (IPVD) and arterial gas abnormalities. Its occurrence has been described in up to 32% of cirrhotic candidates for liver transplantation. It also affects non-cirrhotic patients with portal hypertension. Its pathogenesis is not well defined, but an association of factors such as imbalance in the endothelin receptor response, pulmonary microvascular remodeling and genetic predisposition is thought to lead to IPVD. Diagnosis is based on imaging methods that identify these dilatations, such as contrast echocardiography or perfusion scintigraphy with 99mTc, as well as analysis of arterial gases to identify elevated alveolar-arterial differences in O2 or hypoxemia. There is no effective pharmacological treatment and complete resolution only occurs through liver transplantation. The importance of diagnosing HPS lies in prioritizing transplant candidates, since presence of HPS is associated with worse prognosis. The aim of this paper was to review the pathogenetic theories and current diagnostic criteria regarding HPS, and to critically analyze the prioritization of patients with HPS on the liver transplant waiting list. Searches were carried out in the Medline (Medical Literature Analysis and Retrieval System Online) via PubMed, Cochrane Library and Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde) databases for articles published between January 2002 and December 2007 involving adults and written either in English or in Portuguese, using the term hepatopulmonary syndrome. The studies of greatest relevance were included in the review, along with text books and articles cited in references that were obtained through the review. PMID:20011928

    Full Text Available Abstract Hypoplastic left heart syndrome(HLHS refers to the abnormal development of the left-sided cardiac structures, resulting in obstruction to blood flow from the left ventricular outflow tract. In addition, the syndrome includes underdevelopment of the left ventricle, aorta, and aortic arch, as well as mitral atresia or stenosis. HLHS has been reported to occur in approximately 0.016 to 0.036% of all live births. Newborn infants with the condition generally are born at full term and initially appear healthy. As the arterial duct closes, the systemic perfusion becomes decreased, resulting in hypoxemia, acidosis, and shock. Usually, no heart murmur, or a non-specific heart murmur, may be detected. The second heart sound is loud and single because of aortic atresia. Often the liver is enlarged secondary to congestive heart failure. The embryologic cause of the disease, as in the case of most congenital cardiac defects, is not fully known. The most useful diagnostic modality is the echocardiogram. The syndrome can be diagnosed by fetal echocardiography between 18 and 22 weeks of gestation. Differential diagnosis includes other left-sided obstructive lesions where the systemic circulation is dependent on ductal flow (critical aortic stenosis, coarctation of the aorta, interrupted aortic arch. Children with the syndrome require surgery as neonates, as they have duct-dependent systemic circulation. Currently, there are two major modalities, primary cardiac transplantation or a series of staged functionally univentricular palliations. The treatment chosen is dependent on the preference of the institution, its experience, and also preference. Although survival following initial surgical intervention has improved significantly over the last 20 years, significant mortality and morbidity are present for both surgical strategies. As a result pediatric cardiologists continue to be challenged by discussions with families regarding initial decision

  10. Clinical efficacy of intra-arterial thrombolsis for basilar artery occlusion

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy and influence of intra-arterial thrombolysis for basilar artery occlusion. Methods: Thirty-three consecutive cases of basilar artery occlusion treated by intra-arterial thrombolysis were retrospectively reviewed. They were 25 males and 8 females aged from 28 to 71 years old (average: 56±11 years). The recovery was graded by Glasgow outcome scale, which 1 to 3 point is unfavorable and 4 to 5 is favorable. The short-term follow-up was performed referring to the medical record at the time of discharge and the long-term follow-up was performed by telephone. The differences between the favorable and unfavorable, including sex, age, time to thrombolysis, dizziness, nystagmus, coma, bilateral babinski syndrome, occlusive part, revascularization, angioplasty and its type, were compared by Fisher exact test where P<0.05 was significant. Results: The short-term follow-up was evaluated during the admission (2 to 63 days, 21±16 days). Eighteen eases were favorable and 15 cases were unfavorable and 3 cases died. Twenty one cases showed revascularization and 19 cases showed bilateral positive Babinski sign. The positive Babinski sign, revascularization and coma had significant difference between the favorable and unfavorable (P<0.05). The sex, age, time to thrombolysis between the favorable and unfavorable showed no statistical difference. The long-term follow-up were performed after 1 year and 9 cases missed. 15 of them were favorable and 6 were unfavorable (4 cases died). Conclusion: The intra-arterial thrombolysis could improved the prognosis of basilar artery occlusion. (authors)

  11. Imaging spectrum of primary antiphospholipid antibody syndrome

    International Nuclear Information System (INIS)

    Antiphospholipid antibody syndrome is recognized as one of the most important causes of hypercoagulability. It can be clinically diagnosed if patients have experienced unexplained recurrent venous or arterial thrombosis, recurrent fetal loss, or thrombocytopenia in the presence of circulating autoantibodies to phospholipids, such as anticardiolipin antibody or lupus anticoagulant. Approximately half of all patients with this syndrome do not have associated systemic disease, and their condition is described as primary antiphospholipid antibody syndrome (PAPS). In the remainder, the syndrome is accompanied by systemic lupus erythematosus or other connective tissue diseases, and is known as secondary antiphospholipid syndrome (1). The purpose of this paper is to illustrate the systemic manifestation of PAPS, focusing on the radiological findings of CT, MR and angiography in clinically proven patients.

    International Nuclear Information System (INIS)

    The May-Thurner syndrome is a well-known anatomical anomaly where the left common iliac vein (LCIV) is compressed between the right common iliac artery and the fifth vertebral body. This report describes the case of a 'right-sided' May-Thurner syndrome where the right common iliac vein (RCIV) is compressed by the left common iliac artery in a patient with a left-sided inferior vena cava (IVC). A 26-year-old woman was admitted to our institution with acute edema of the right lower limb. The diagnosis of May-Thurner syndrome was done by CT scan and confirmed by phlebography. An endovascular treatment with stenting was carried out, with good patency and clinical result at 12-month follow-up.

    For diagnosing of polycystic ovary syndrome (PCOS) it is currently recommended to follow the ESHRE criteria. For diagnosis according to them two of the following three symptoms are sufficient: 1. morphology of polycystic ovaria, 2. clinical manifestations of hyperandrogenism or laboratory proof of hyperandrogenemia, and 3. oligo-anovulation. PCOS is a complex disorder in whose pathogenesis genetic and environmental effects interact. It is not a gynecological disorder alone, the syndrome is accompanied by insulin resistance which leads to increased incidence of type 2 diabetes mellitus and impaired glucose tolerance (4 times and twice, independently of BMI). Also gestational DM occurs more frequently. Dyslipidemia, arterial hypertension, elevated CRP and homocysteine levels, endothelial dysfunction and greater intima-media thickness are also more frequent. It is not quite clear, however, whether women with PCOS suffer cardiovascular events more frequently as well. More often than is accidental PCOS is associated with depression, anxiety and eating disorders, further with nonalcoholic steatohepatitis and with the sleep apnoea syndrome - especially in obese women. Therapeutic measures include non-pharmacological methods - lifestyle adjustments focused on weight reduction in obese individuals, cosmetic measures for dermatologic manifestation of hyperandrogenism, in particular laser and pharmacotherapy (combined hormonal contraceptives and antiandrogens). Menstrual irregularities can be treated with contraceptives or cyclical administration of gestagens, also metformin can be used. PMID:26486483

    Poland's syndrome is a rare congenital anomaly characterized by unilateral chest wall hypoplasia and ipsilateral hand abnormalities. Literary data suggest its sporadic nature. The prevailing theory of its cause is hypoplasia of the subclavian artery or its branches, which may lead to a range of developmental changes. The incidence of Poland's syndrome varies between groups (male versus female patients, congenital versus familial cases, and so on) and ranges from 1 in 7,000 to 1 in 100,000 live births. Cases of Poland's syndrome associated with leukemia, carcinoma of the hypoplastic breast, and other conditions, confirm the relationship between developmental defects and tumors, and require oncologic awareness. Various manifestations, age, and gender require different surgical approaches. Our experience, which includes 27 patients (15 male, 12 female), 20 of whom (12 male, 8 female) underwent operation, suggests that the repair should be done in two stages in children and in a single stage in adults. Reconstruction and/or stabilization of the aplastic ribs may be achieved using bone grafts or prosthetic mesh. Muscle flaps and breast implants may be used to correct muscle deficiency and breast hypoplasia and to help achieve a complete cosmetic repair. PMID:12643435

    Arterial stiffness has been recognized as a marker of cardiovascular disease and associated with long-term worse clinical outcomes in several populations. Age, hypertension, smoking, and dyslipidemia, known as traditional vascular risk factors, as well as diabetes, obesity, and systemic inflammation lead to both atherosclerosis and arterial stiffness. Targeting multiple modifiable risk factors has become the main therapeutic strategy to improve arterial stiffness in patients at high cardiovascular risk. Additionally to life style modifications, long-term ω-3 fatty acids (fish oil) supplementation in diet may improve arterial stiffness in the population with hypertension or metabolic syndrome. Pharmacological treatment such as renin-angiotensin-aldosterone system antagonists, metformin, and 3-hydroxy-3-methyl-glutaryl-CoA reductase inhibitors were useful in individuals with hypertension and diabetes. In obese population with obstructive sleep apnea, weight reduction, aerobic exercise, and continuous positive airway pressure treatment may also improve arterial stiffness. In the populations with chronic inflammatory disease such as rheumatoid arthritis, a use of antibodies against tumor necrosis factor-alpha could work effectively. Other therapeutic options such as renal sympathetic nerve denervation for patients with resistant hypertension are investigated in many ongoing clinical trials. Therefore our comprehensive review provides knowledge in detail regarding many aspects of pathogenesis, measurement, and management of arterial stiffness in several populations, which would be helpful for physicians to make clinical decision.

    A few isolated reports have described an association between Noonan syndrome and cerebrovascular abnormalities, including moyamoya syndrome. These reports have been limited to pediatric patients presenting with recurrent transient ischemic attacks (TIA) or headaches. Management has primarily been pharmacologic, with only one prior report of surgical revascularization to our knowledge. We report four cases of Noonan syndrome patients presenting with headaches and/or sensorimotor strokes in childhood that caused unilateral sensorimotor impairment. Cerebral angiography and MRI revealed bilateral moyamoya syndrome. All patients underwent successful bilateral extracranial-to-intracranial revascularization. The first patient was a 10-year-old girl who presented following a hemorrhagic stroke and recovered well after indirect bypass. The second patient was an adult with a history of childhood stroke whose symptoms progressed in adulthood. She underwent a direct bypass and improved, but continued to experience TIA at her 4 year follow-up. The third patient was a 7-year-old girl with headaches and a new onset TIA who failed pharmacological therapy and subsequently underwent bilateral indirect bypass. The fourth patient was a 24-year-old woman with worsening headaches and an occluded left middle cerebral artery from unilateral moyamoya syndrome. A left sided direct bypass was completed given delayed MRI perfusion with poor augmentation. To our knowledge these are the first reported surgical cases of combined Noonan and moyamoya syndrome. These cases highlight the need to recognize moyamoya syndrome in patients with Noonan syndrome. Early surgical revascularization should be pursued in order to prevent symptom progression.

    Full Text Available Abstract Ehlers-Danlos syndrome type IV, the vascular type of Ehlers-Danlos syndromes (EDS, is an inherited connective tissue disorder defined by characteristic facial features (acrogeria in most patients, translucent skin with highly visible subcutaneous vessels on the trunk and lower back, easy bruising, and severe arterial, digestive and uterine complications, which are rarely, if at all, observed in the other forms of EDS. The estimated prevalence for all EDS varies between 1/10,000 and 1/25,000, EDS type IV representing approximately 5 to 10% of cases. The vascular complications may affect all anatomical areas, with a tendency toward arteries of large and medium diameter. Dissections of the vertebral arteries and the carotids in their extra- and intra-cranial segments (carotid-cavernous fistulae are typical. There is a high risk of recurrent colonic perforations. Pregnancy increases the likelihood of a uterine or vascular rupture. EDS type IV is inherited as an autosomal dominant trait that is caused by mutations in the COL3A1 gene coding for type III procollagen. Diagnosis is based on clinical signs, non-invasive imaging, and the identification of a mutation of the COL3A1 gene. In childhood, coagulation disorders and Silverman's syndrome are the main differential diagnoses; in adulthood, the differential diagnosis includes other Ehlers-Danlos syndromes, Marfan syndrome and Loeys-Dietz syndrome. Prenatal diagnosis can be considered in families where the mutation is known. Choriocentesis or amniocentesis, however, may entail risk for the pregnant woman. In the absence of specific treatment for EDS type IV, medical intervention should be focused on symptomatic treatment and prophylactic measures. Arterial, digestive or uterine complications require immediate hospitalisation, observation in an intensive care unit. Invasive imaging techniques are contraindicated. Conservative approach is usually recommended when caring for a vascular

  20. Exercise thallium scintigraphy in aortitis syndrome (Takayasu's arteritis)

    International Nuclear Information System (INIS)

    It is important for patient management to evaluate coronary arterial involvement in aortitis syndrome. Twenty one cases of aortitis syndrome who experienced chest pain were examined using exercise thallium scintigraphy. The patients were divided into four groups according to the angiographic findings. There were: Five patients with left main coronary arterial involvement (group A), four with left or right coronary arterial involvement (group B), nine with aortic regurgitation (group C), and three with pulmonary arterial involvement (group D). In group A and B, all patients had positive ECGs and thallium perfusion defects. Group A patients showed extensive anterolateral perfusion defects, which were compatible with left main coronary arterial involvement. Group C and D patients, who had normal coronary arteries, showed no remarkable perfusion defects although five had positive ECG findings. Thus, the sensitivity and specificity of exercise scintigraphy for detection of myocardial ischemia were 9/9 and 12/12, while those of stress ECG were 9/9 and 7/12 (58%), respectively. It is recommended that exercise thallium scintigraphy be used for detecting clinically occult but significant coronary arterial involvement in aortitis syndrome with chest pain. (orig.)

Ultrasound diagnosis Prenatal; ultrasound diagnosis has been established in the first trimester, based on the finding of a nuchal lucency. Detectable features on the early second trimester include abnormal forearms, clenched hands, clubbed feet, omphalocele and a major heart defect. The features of trisomy 18 are detectable in 80% of affected fetuses in the second trimester. Sonography is often used to evaluate fetuses for the prsence of trisomy 18 when choroid plexus cysts are present, or when the triple screen results in a low level of maternal serum alpha- fetoprotein, estriol and human chorionic  gonadotropin combination. Although trisomy 18 occurs in 1 in 100 fetuses with choroid plexus cysts, if it is an isolated finding, the risk for trisomy 18 falls below 1 in 400.

    2012-07-01

    Full Text Available A 54-year-old male patient presented with acute myocardial infarction involving left anterior descending and right coronary artery territories. Coronary angiogram showed a single coronary artery with right coronary artery arising from left anterior descending artery (LAD, which coursed anterior to right ventricular outflow tract and thrombotic lesion in mid left anterior descending artery before origin of right coronary artery. The patient was treated with thrombolytic therapy and glycoprotein IIb/IIIa inhibitors. Anomalous origin of right coronary artery as a branch of LAD is a very rare type of congenital coronary artery anomalies. It is important to recognize this anomaly as it can be associated with extensive myocardial ischemia and sudden cardiac death in young persons even without atherosclerosis.

An increase in proinflammatory activity relative to anti-inflammatory activity is considered to cause a progression of the disease towards plaque instability and risk of atherothrombotic events, such as acute coronary syndrome (ACS). Cortisol, the end product of the hypothalamus-pituitary-adrenal (HPA) axis, is a powerful endogenous anti-inflammatory mediator. Disturbances in the...

    Pulmonary arterial hypertension (PAH) is a serious complication of congenital heart disease (CHD). Without early surgical repair, around one-third of paediatric CHD patients develop significant PAH. Recent data from the Netherlands suggest that >4% of adult CHD patients have PAH, with higher rates in those with septal defects. A spectrum of cardiac defects is associated with PAH-CHD, although most cases develop as a consequence of large systemic-to-pulmonary shunts. Eisenmenger's syndrome, ch...

    CrossFit is a high-intensity strength and conditioning program that has gained popularity over the past decade. Potential injuries associated with CrossFit training have been suggested in past reports. We report three cases of cervical carotid dissection that are associated with CrossFit workouts. Patient 1 suffered a distal cervical internal carotid artery (ICA) dissection near the skull base and a small infarct in Wernicke's area. He was placed on anticoagulation and on follow-up has near complete recovery. Patient 2 suffered a proximal cervical ICA dissection that led to arterial occlusion and recurrent middle cerebral artery territory infarcts and significant neurological sequelae. Patient 3 had a skull base ICA dissection that led to a partial Horner's syndrome but no cerebral infarct. While direct causality cannot be proven, intense CrossFit workouts may have led to the ICA dissections in these patients. PMID:25917634

    Congenital heart diseases are the most common congenital malformations and account for about eight cases per 1000 births and are often associated with pulmonary arterial hypertension. Increased shear stress and the excess flow through the pulmonary vascular bed due to a systemic-to-pulmonary shunt lead to the development of pulmonary vascular disease and an increase in pulmonary vascular resistance. Without surgical repair approximately 30% of patients develop pulmonary vascular disease. Eisenmenger syndrome represents the extreme end of pulmonary arterial hypertension with congenital heart disease. We summarized the current therapeutic options for pulmonary arterial hypertension; conventional treatments including calcium channel blockers, anticoagulation, digitalis, diuretics, and new treatment: prostacyclin, bosentan, sildenafil, ambrisentan. Preliminary data of new therapies are encouraging with disease significantly improved natural history, but there is need for more evidence-based data. PMID:18333354

    Full Text Available The urofacial syndrome is characterized by functional obstructive uropathy asso-ciated with an inverted smile. The importance of the subject is that it sheds light, not only on the muscles of facial expression, but also on the inheritance of voiding disorders and lower urinary tract malformations. We report a 10-year-old-male patient who had the urofacial syndrome. Early diagnosis of the urofacial syndrome is important to avoid upper urinary tract damage and renal failure.

    Auditory-pigmentary syndromes are caused by physical absence of melanocytes from the skin, hair, eyes, or the stria vascularis of the cochlea. Dominantly inherited examples with patchy depigmentation are usually labelled Waardenburg syndrome (WS). Type I WS, characterised by dystopia canthorum, is caused by loss of function mutations in the PAX3 gene. Type III WS (Klein-Waardenburg syndrome, with abnormalities of the arms) is an extreme presentation of type I; some but not all patients are ho...

    Full Text Available The Metabolic syndrome is a widely prevalent and multi-factorial disorder. The syndrome has been given several names, including- the metabolic syndrome, the insulin resistance syndrome, the plurimetabolic syndrome, and the deadly quartet. With the formulation of NCEP/ATP III guidelines, some uniformity and standardization has occurred in the definition of metabolic syndrome and has been very useful for epidemiological purposes. The mechanisms underlying the metabolic syndrome are not fully known; however resistance to insulin stimulated glucose uptake seems to modify biochemical responses in a way that predisposes to metabolic risk factors. The clinical relevance of the metabolic syndrome is related to its role in the development of cardiovascular disease. Management of the metabolic syndrome involves patient-education and intervention at various levels. Weight reduction is one of the main stays of treatment. In this article we comprehensively discuss this syndrome- the epidemiology, pathogenesis, clinical relevance and management. The need to do a comprehensive review of this particular syndrome has arisen in view of the ever increasing incidence of this entitiy. Soon, metabolic syndrome will overtake cigarette smoking as the number one risk factor for heart disease among the US population. Hardly any issue of any primary care medical journal can be opened without encountering an article on type 2 diabetes, dyslipidemia or hypertension. It is rare to see type 2 diabetes, dyslipidemia, obesity or hypertension in isolation. Insulin resistance and resulting hyperinsulinemia have been implicated in the development of glucose intolerance (and progression to type 2 diabetes, hypertriglyceridemia, hypertension, polycystic ovary yndrome, hypercoagulability and vascular inflammation, as well as the eventual development of atherosclerotic cardiovascular disease manifested as myocardial infarction, stroke and myriad end organ diseases.

    Full Text Available Brugada syndrome is characterized by sudden death associated with one of several ECG patterns including incomplete right bundle-branch block and ST-segment elevation in the anterior precordial leads. According to the ECG patterns there are three types of Brugada syndrome. Brugada syndrome is genetically determined and has an autosomal dominant pattern of transmission in about 50% of familial cases. Nowadays implantation of cardioverter-defibrillator is the only proven method of sudden cardiac death prevention.
