    Acute thoracic aortic syndromes encompass a spectrum of emergencies including aortic dissection, intramural haematoma, penetrating atherosclerotic ulcer and aneurysm rupture. All these life-threatening conditions require prompt diagnosis and appropriate management. To date multi-detector row Computed Tomography represents a valuable diagnostic tool especially in the emergency setting. This paper focus on the use of multi-detector row Computed Tomography in the evaluation of acute thoracic aortic syndromes and illustrates the key imaging findings related to each disease.

    Advances in medical therapy and non-surgical percutaneous options to manage the specter of acute aortic syndromes have improved both patient morbidity and mortality. There are key features in the patient history and initial exam which physicians should be attuned to in order to diagnose acute aortic syndromes such as aortic dissection, penetrating aortic ulcer, and intramural hematoma. Once recognized, early initiation of the appropriate pharmacologic therapy is important, and further appreciating the limitations of such therapy before considering a surgical approach is critical to improve patient outcomes. For the undifferentiated patient with acute aortic dissection presenting to facilities who do not routinely manage this condition, adding pharmacologic agents in the correct sequence assures the best chance for a satisfactory outcome.

    Abstract In acute aortic syndromes (AAS), organ malperfusion represents a key event impacting both on diagnosis and outcome. Increased levels of plasma lactate dehydrogenase (LDH), a biomarker of malperfusion, have been reported in AAS, but the performance of LDH for the diagnosis of AAS and the relation of LDH with outcome in AAS have not been evaluated so far. This was a bi-centric prospective diagnostic accuracy study and a cohort outcome study. From 2008 to 2014, patients from 2 Emergency...

    Full Text Available Marfan syndrome is an autosomal dominant inherited disorder of connective tissue, with various complications manifested primarily in the cardiovascular system. It potentially leads to aortic dissection and rupture, these being the major causes of death. We report a patient who complained of acute abdominal pain, which presented as acute mesenteric ischemia combined with abdominal aortic dissection. Echocardiography showed enlargement of the aortic root and mitral valve prolapse. Abdominal computed tomography scan revealed acute mesenteric ischemia due to abdominal aortic dissection. Finally, the patient underwent surgery of aortic root replacement and had a successful outcome. Therefore, we suggest that for optimal risk assessment and monitoring of patients with Marfan syndrome, both aortic stiffness and the diameter of the superior mesenteric vein compared with that of the superior mesenteric artery are useful screening methods to detect acute mesenteric ischemia secondary to abdominal aortic dissection. Early diagnosis and early treatment can decrease the high mortality rate of patients with Marfan syndrome.

    Abstract In acute aortic syndromes (AAS), organ malperfusion represents a key event impacting both on diagnosis and outcome. Increased levels of plasma lactate dehydrogenase (LDH), a biomarker of malperfusion, have been reported in AAS, but the performance of LDH for the diagnosis of AAS and the relation of LDH with outcome in AAS have not been evaluated so far. This was a bi-centric prospective diagnostic accuracy study and a cohort outcome study. From 2008 to 2014, patients from 2 Emergency Departments suspected of having AAS underwent LDH assay at presentation. A final diagnosis was obtained by aortic imaging. Patients diagnosed with AAS were followed-up for in-hospital mortality. One thousand five hundred seventy-eight consecutive patients were clinically eligible, and 999 patients were included in the study. The final diagnosis was AAS in 201 (20.1%) patients. Median LDH was 424 U/L (interquartile range [IQR] 367–557) in patients with AAS and 383 U/L (IQR 331–460) in patients with alternative diagnoses (P < 0.001). Using a cutoff of 450 U/L, the sensitivity of LDH for AAS was 44% (95% confidence interval [CI] 37–51) and the specificity was 73% (95% CI 69–76). Overall in-hospital mortality for AAS was 23.8%. Mortality was 32.6% in patients with LDH ≥ 450 U/L and 16.8% in patients with LDH < 450 U/L (P = 0.006). Following stratification according to LDH quartiles, in-hospital mortality was 12% in the first (lowest) quartile, 18.4% in the second quartile, 23.5% in the third quartile, and 38% in the fourth (highest) quartile (P = 0.01). LDH ≥ 450 U/L was further identified as an independent predictor of death in AAS both in univariate and in stepwise logistic regression analyses (odds ratio 2.28, 95% CI 1.11–4.66; P = 0.025), in addition to well-established risk markers such as advanced age and hypotension. Subgroup analysis showed excess mortality in association with LDH ≥ 450 U/L in elderly, hemodynamically stable

    Full Text Available The incidence of acute aortic syndrome is low, but the spontaneous course is often life-threatening. Adequate ECG-gated imaging is fundamental within the diagnostic workup. We here report a case of a 53-year-old man presenting with atypical chest pain, slight increase of D dimers at admission, and extended diameter of the ascending aorta accompanied by mild aortic regurgitation. Interpretation of an initial contrast-enhanced computed tomography was false negative due to inadequate gating and motion artifacts, thereby judging a tiny contrast signal in the left anterior quadrant of the ascending aorta as a pseudointimal flap. By hazard, cardiac magnetic resonance imaging demonstrated an ulcer-like lesion superior to the aortic root, leading to aortic surgery at the last moment. As sensitivity of imaging is not 100%, this example underlines that second imaging studies might be necessary if the first imaging is negative, but the clinical suspicion still remains high.

    We report a case of a 63-year-old man, with a previous history of hypertension and glucose intolerance associated troncular obesity that was emergently admitted to our Institution for evaluation of a severe, constant posterior chest pain which radiated anteriorly and dyspnoea with a suspected diagnosis of acute aortic dissection. A CT scan of thorax and abdomen demonstrated a dissection starting just below left succlavian artery and extending downward to the left renal artery, involving the celiac tripod and superior mesenteric artery. The dissection was classified as Stanford B, De Bakey III. Moreover, CT scan of abdomen revealed incidentally a left adrenal tumor of 25 mm of diameter. An emergent prosthetic graft was placed just below the origin of the left succlavian artery up-to the diaphragmatic hiatus. Furthermore, a diagnostic evaluation of the mass revealed an increase of cortisol production, and a diagnosis of Cushing's syndrome was done and the patient underwent an adrenalectomy via laparotomic approach. We report an association of acute aortic dissection of acute aortic dissection type B associated to Cushing's syndrome.

    Acute aortic syndromes (AAS) encompass a spectrum of emergencies. These include those non-traumatic disease entities of the aorta namely, penetrating atherosclerotic ulcer, intramural haematoma, dissection and aneurysm rupture. The various types of AAS cannot be reliably differentiated on clinical grounds alone. Acute thoracic aortic injury is usually included in this group even though clinical presentation is different, i.e., in the context of trauma, the imaging features are very similar. Differentiation of AAS from acute coronary syndrome (ACS) is important, however, it must be remembered that ACS may occur as a result of AAS. Now electrocardiogram (ECG)-gating technology is widely available, ECG-gated multi-detector row computed tomography (MDCT) is a powerful clinical tool in the acute emergency setting, which enables rapid and specific diagnosis of aortic pathology. ECG-gated MDCT significantly reduces motion artefact, avoids potential pitfalls in diagnosis and often provides diagnostic information about the coronary arteries. It should be used as a first-line imaging technique. This article examines the role of MDCT imaging and cardiac gating in the assessment of AAS and discusses the differentiation of this spectrum of aortic diseases with reference to the key imaging findings as obtained by experience in our institution.

    An evaluation is presented on the clinical, pathological and sociodemographic characteristics of a sample of sudden death victims secondary to an Acute Aortic Syndrome (AAS) in the north of Portugal, submitted to medico-legal autopsy, during the period between January 2008 and December 2012. Autopsy reports were analyzed in which, through necropsy and histological examination, the confirmed cause of death was an Acute Aortic Syndrome. From the studied cases, 70.3% of the victims were male. The median age was 65,19 ± 14,35 years (minimum of 27 years and maximum of 88 years). Death occurred mainly at home (40,5%) and during the normal activities of daily living (43,1%). There was an history of prodromes in 64,9% of the cases, mainly syncope and pain or respiratory symptoms. In 62,2% of the cases no pain history was reported. In the internal examination three presentation forms were identified: cardiac tamponade (51,4%); hemotorax (16,2%) and intra-abdominal bleeding (32,4%). The occurence of an Acute Aortic Syndrome was related to an aneurysmatic formation in 81% of the cases. Atherosclerotic plaques were identified in 51,4% of the cases and left ventricular hypertrophy was identified in 54,1%. None of the victims had a family history of aortic pathology and 54,1% of them presented a history of arterial hypertension. Necropsy data analysis of sudden death victims allows a better understanding of the AAS presentation, thus complementing the existent clinical studies. This work reveals how forensic medicine can be a privileged medium for articulation with clinical practice.

    We investigated frequency/characteristics of acute coronary syndrome-like (ACS-like) electrocardiographic (ECG) profiles among patients with a final diagnosis of acute aortic syndrome (AAS), and explored pathophysiologic determinants and prognostic relevance within each Stanford subtype. We blindly reviewed presentation electrocardiograms of 233 consecutive patients with final diagnosis of AAS (164 Stanford type A) at a regional treatment center. Prevalence of ACS-like ECG findings was 27% (type A, 26%, type B, 29%); most were non-ST-elevation myocardial infarction-like. Patients with ACS-like ECG findings more often had coronary ostia involvement (p=0.002), pleural effusion (p=0.02), significant aortic regurgitation (p=0.01), and troponin positivity (p=0.001). ACS-like ECG profile in type A disease was independently associated with coronary ostia involvement (odds ratio [OR] 5.27, 95% confidence interval [CI] 1.75 to 15.88). ACS-like ECG profile predicted in-hospital mortality (OR 2.90, 95% CI 1.24 to 6.12), as did age (each incremental 10-year: OR 1.59, 95% CI 1.14 to 2.22), and syncope at presentation (OR 2.90, 95% CI 1.16 to 7.24). In conclusion, about 25% of our AAS patients (in either Stanford subtype) presented ACS-like ECG patterns-often with non-ST-elevation myocardial infarction characteristics-which could cause misdiagnosis. ACS-like ECG profile was associated with more complicated disease, and in type A disease was a strong independent predictor of in-hospital mortality.

    Aortic dissection is a lethal complication in pregnant women with Marfan syndrome. To decrease arterial wall stress, beta-blockers have been used as standard treatment, although uterine contractions caused by beta-2-adrenergic receptor antagonism may result. Herein, we report a patient with Marfan syndrome who was given landiolol, a selective beta-1-adrenergic receptor antagonist with a short half-life, for management during a Cesarean section procedure following development of acute aortic dissection. A 30-year-old pregnant woman with Marfan syndrome in the 38th week of gestation was referred to our department for an emergency Cesarean section because of development of acute aortic dissection. Blood pressure (BP) decreased from 157/70 to 128/64 mmHg after giving nicardipine and nitroglycerin. However, heartrate (HR) increased from 112 to 145 bpm, which was reduced to 105 bpm with landiolol, while BP was maintained. A Cesarean section was performed without complications under combined spinal-epidural anesthesia. Hemodynamic state, uterine contraction, and the extent of aortic dissection remained stable. The postoperative course was uneventful, and the patient and her baby were discharged safely. Landiolol was useful for reduction of HR without affecting BP or uterine contractions during a Cesarean section procedure in our patient with aortic dissection.

    Marfan syndrome (MFS) is an autosomal dominant connective tissue disease associated with acute aortic dissection (AAD). We used 2 large registries that include patients with MFS to investigate possible trends in the chronobiology of AAD in MFS. We queried the International Registry of Acute Aortic Dissection (IRAD) and the Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) registry to extract data on all patients with MFS who had suffered an AAD. The group included 257 patients with MFS who suffered an AAD from 1980 to 2012. The chi-square tests were used for statistical testing. Mean subject age at time of AAD was 38 years, and 61% of subjects were men. AAD was more likely in the winter/spring season (November to April) than the other half of the year (57% vs 43%, p = 0.05). Dissections were significantly more likely to occur during the daytime hours, with 65% of dissections occurring from 6 a.m. to 6 p.m. (p = 0.001). Men were more likely to dissect during the daytime hours (6 a.m. to 6 p.m.) than women (74% vs 51%, p = 0.01). These insights offer a glimpse of the times of greatest vulnerability for patients with MFS who suffer from this catastrophic event. In conclusion, the chronobiology of AAD in MFS reflects that of AAD in the general population.

Diffuse intra-aortic thrombi were revealed by computed tomography with contrast media, and magnetic resonance imaging showed spinal cord infarction. However, computed tomography scans of the descending aorta obtained 4 months before admission exhibited no signs of atherosclerotic plaques or intra-aortic thrombi. Laboratory data suggest that antiphospholipid antibody syndrome might have caused these acute multiple intra-arterial thrombi. By restarting dual antiplatelet therapy and increasing the dose of heparin (from 10,000 IU/day to 15,000 IU/day we successfully managed the patient's clinical condition and symptoms. It is important to understand that stopping antiplatelet therapy may rapidly grow thrombi in patients with a hypercoagulative state.Keywords: intra-aortic thrombus, antiphospholipid antibody syndrome, spinal cord infarction

    Marfan syndrome is a hereditary disease with a prevalence of 2-3 in 10,000 births, leading to a fibrillin connective tissue disorder with manifestations in the skeleton, eye, skin, dura mater and in particular the cardiovascular system. Since other syndromes demonstrate similar vascular manifestations, but therapy may differ significantly, diagnosis should be established using the revised Ghent nosology in combination with genotypic analysis in specialized Marfan centres. The formation of aortic root aneurysms with the subsequent risk of acute aortic dissection type A (AADA) or aortic rupture limits life expectancy in patients with Marfan syndrome. Therefore, prophylactic replacement of the aortic root needs to be performed before the catastrophic event of AADA can occur. The goal of surgery is the complete resection of pathological aortic tissue. This can be achieved with excellent results by using a (mechanically) valved conduit that replaces both the aortic valve and the aortic root (Bentall operation). However, the need for lifelong anticoagulation with Coumadin can be avoided using the aortic valve sparing reimplantation technique according to David. The long-term durability of the reconstructed valve is favourable, and further technical improvements may improve longevity. Although results of prospective randomised long-term studies comparing surgical techniques are lacking, the David operation has become the surgical method of choice for aortic root aneurysms, not only at the Heidelberg Marfan Centre. Replacement of the aneurysmal dilated aortic arch is performed under moderate hypothermic circulatory arrest combined with antegrade cerebral perfusion using a heart-lung machine, which we also use in thoracic or thoracoabdominal aneurysms. Close post-operative follow-up in a Marfan centre is pivotal for the early detection of pathological changes on the diseased aorta.

    A predisposition for thoracic aortic aneurysms leading to acute aortic dissections can be inherited in families in an autosomal dominant manner. Genome-wide linkage analysis of two large unrelated families with thoracic aortic disease, followed by whole exome sequencing of affected relatives, identified causative mutations in TGFB2. These mutations, a frameshift mutation in exon 6 and a nonsense mutation in exon 4, segregated with disease with a combined LOD score of 7.7. Sanger sequencing of 276 probands from families with inherited thoracic aortic disease identified two additional TGFB2 mutations. TGFB2 encodes the transforming growth factor beta-2 (TGF-β2) and the mutations are predicted to cause haploinsufficiency for TGFB2, but aortic tissue from cases paradoxically shows increased TGF-β2 expression and immunostaining. Thus, haploinsufficiency of TGFB2 predisposes to thoracic aortic disease, suggesting the initial pathway driving disease is decreased cellular TGF-β2 levels leading to a secondary increase in TGF-β2 production in the diseased aorta.

    Multimodal imaging plays a pivotal role in the assessment of the thoracic aorta, both in chronic and acute settings. Moving from improved knowledge on the structure and function of the aortic wall, as well as on its pathophysiology and histopathology, appropriate utilization of each imaging modality results into a better definition of the patient's need and proper treatment strategy. This review is aimed at highlighting the most critical aspects in this field, providing cardiologists with some novel clues for the imaging approach to patients with thoracic aortic disease.

    Background Although triple rule-out CT angiography (TRO) to simultaneously evaluate acute coronary syndrome (ACS), pulmonary embolism (PE), and acute aortic syndrome (AAS) is increasingly used in many institutions, TRO is inevitably associated with increased radiation exposure due to extended z-axis coverage compared with dedicated coronary CT angiography (DCTA). Purpose To determine the frequency of exclusion of findings of AAS, PE, and significant incidental non-cardiac pathology that may be the cause of acute chest pain when using a restricted DCTA field of view (FOV). Material and Methods We retrospectively reviewed CT images and charts of 103 patients with acute PE and 50 patients with AAS. Either non-ECG gated dedicated pulmonary or aortic CT angiography was performed using 16- or 64-slice multidetector CT (MDCT). We analyzed the incidence of isolated PE, AAS, or significant non-cardiac pathology outside of DCTA FOV (i.e. from tracheal carina to the base of heart). Results There were two cases of isolated PE (2/103, 1.9%) excluded from the FOV of DCTA. One case of PE was isolated to the subsegmental pulmonary artery in the posterior segment of the right upper lobe. In the second case, pulmonary embolism in the left main pulmonary artery was located out of the FOV of DCTA because the left main pulmonary artery was retracted upwardly by fibrotic scar in the left upper lobe due to prior tuberculosis. There was no case of AAS and significant non-cardiac pathology excluded from the FOV of DCTA. AAS (n = 50) consisted of penetrating atherosclerotic ulcer (n = 7), intramural hematoma (n = 5) and aortic dissection (n = 38). Conclusion As isolated PE, AAS, and significant non-cardiac pathology outside of the DCTA FOV rarely occur, DCTA may replace TRO in the evaluation of patients with non-specific acute chest pain and a low pre-test probability of PE or aortic dissection

    In addition to organovascular arterial ischemic diseases (cardiovascular, vasculovascular, neurovascular, extre-mitovascular, renovascular, genitovascular, bronchopulmovascular, mesenteriovascular, osteoarthromusculovascular, dermovascular, oculovascular, otovascular, stomatovascular etc.), aortic diseases contribute to the wide spectrum of arterial diseases: aortic aneurysms (AA), acute aortic syndromes (AAS) including aortic dissection (AD), intramural haematoma (IMH), penetrating atherosclerotic ulcer (PAU) and traumatic aortic injury (TAI), pseudoaneurysm, aortic rupture, atherosclerosis, vasculitis as well as genetic diseases (e.g. Turner syndrome, Marfan syndrome, Ehlers-Danlos syndrome) and congenital abnormalities including the coarctation of the aorta (CoA). Similarly to other arterial diseases, aortic diseases may be diagnosed after a long period of subclinical development or they may have an acute presentation. Acute aortic syndrome is often the first sign of the disease, which needs rapid diagnosis and decisionmaking to reduce the extremely poor prognosis. Key clinical-etiology-anatomy-patophysiology (CEAP) diagnostic aspects of aortic diseases are discussed in this document (project Vessels).

    Full Text Available Abstract Background Acute aortic dissection (AAD is a life-threatening condition requiring immediate assessment and therapy. A patient suffering from AAD often presents with an insignificant or irrelevant medical history, giving rise to possible misdiagnosis. The aim of this retrospective study is to address the problem of misdiagnosing AD and the different imaging studies used. Methods From January 2000 to December 2004, 49 patients (41 men and 8 women, aged from 18–75 years old presented to the Emergency Department of our hospital for different reasons and finally diagnosed with AAD. Fifteen of those patients suffered from arterial hypertension, one from giant cell arteritis and another patient from Marfan's syndrome. The diagnosis of AAD was made by chest X-ray, contrast enhanced computed tomography (CT, transthoracic echocardiography (TTE and coronary angiography. Results Initial misdiagnosis occurred in fifteen patients (31% later found to be suffering from AAD. The misdiagnosis was myocardial infarction in 12 patients and cerebral infarction in another three patients. Conclusion Aortic dissection may present with a variety of clinical manifestations, like syncope, chest pain, anuria, pulse deficits, abdominal pain, back pain, or acute congestive heart failure. Nearly a third of the patients found to be suffering from AD, were initially otherwise diagnosed. Key in the management of acute aortic dissection is to maintain a high level of suspicion for this diagnosis.

    Full Text Available Acute aortic syndrome is a pathological process with low incidence compared with acute coronary syndrome, although with a worse prognosis in the short term, which is why its early diagnosis and urgent treatment are essential to the favorable evolution of thepatient. Electrocardiographic changes suggestive of myocardial ischemia, with acute evolution, are rare in acute aortic syndrome. Even in the presence of a suggestive thoracic pain and high levels of blood pressure, an adequate differential diagnosis is of utmost importance, since the administration of anticoagulation and antiplatelet therapy in high doses can have a dramatic impact on patient outcome. Two cases are presented in which electrocardiographic changes determined the action to take in patients with acute aortic syndrome.

    Acute aortic dissection is a rare disease, but if it occurs rapid diagnosis and therapy are needed. It is usually seen in elderly patients with long-term persistent arterial hypertension. In younger patients, it is mainly caused by congenital connective tissue disorders, such as Marfan syndrome, or by trauma. We present here a 34-year-old male patient with an acute type A aortic dissection. This patient was a professional parachutist and had carried out a large number of parachute jumps during his lifetime. He was admitted to the emergency department with acute chest pain. The symptoms were not related in time to a parachute jump. During a computed tomography scan, an aortic dissection was diagnosed. The patient was immediately referred to the operating room, and the ascending aorta was replaced by a conduit. After a regular postoperative course, the patient was discharged and recovered completely. Although acute aortic dissection is rare in young patients, it has to be considered in cases of acute chest pain. An immediate diagnosis and adequate therapy are essential to offer the patient a good clinical outcome and long-term survival.

    2016-07-01

    For the management of acute aortic syndromes, regional treatment networks have been established to coordinate diagnosis and treatment between local emergency rooms and central specialized centers. Triage of acute aortic syndromes requires definitive imaging, resulting in complex data files. Modern information technology network structures, specifically "cloud" technology, coupled with mobile communication, increasingly support sharing of these data in a network of experts using mobile, online access and communication. Although this network is technically complex, the potential benefit of online sharing of data files between professionals at multiple locations within a treatment network appear obvious; however, clinical experience is limited, and further evaluation is needed.

  12. Vasopressor mechanisms in acute aortic coarctation hypertension

    Directory of Open Access Journals (Sweden)

    1997-01-01

    Full Text Available Angiotensin II (ANG II and vasopressin (AVP act together with the mechanical effect of aortic constriction in the onset of acute aortic coarctation hypertension. Blockade of ANG II and AVP V1 receptors demonstrated that ANG II acts on the prompt (5 min rise in pressure whereas AVP is responsible for the maintenance (30-45 min of the arterial pressure elevation during aortic coarctation. Hormone assays carried out on blood collected from conscious rats submitted to aortic constriction supported a role for ANG II in the early stage and a combined role for both ANG II and AVP in the maintenance of proximal hypertension. As expected, a role for catecholamines was ruled out in this model of hypertension, presumably due to the inhibitory effect of the sinoaortic baroreceptors. The lack of afferent feedback from the kidneys for AVP release from the central nervous system in rats with previous renal denervation allowed ANG II to play the major role in the onset of the hypertensive response. Median eminence-lesioned rats exhibited a prompt increase in proximal pressure followed by a progressive decline to lower hypertensive levels, revealing a significant role for the integrity of the neuroaxis in the maintenance of the aortic coarctation hypertension through the release of AVP. In conclusion, the important issue raised by this model of hypertension is the likelihood of a link between some vascular territory - probably renal - below the coarctation triggering the release of AVP, with this vasoconstrictor hormone participating with Ang II and the mechanical effect of aortic constriction in the acute aortic coarctation hypertension

    Almost one-quarter of patients presenting with thoracic aortic aneurysms (TAAs) or acute aortic dissections (TAADs) have an underlying mutation in a specific gene. A subset of these patients will have systemic syndromic features, for example, skeletal features in patients with Marfan Syndrome. It is important to note that the majority of patients with thoracic aortic disease will not have these syndromic features but many will have a family history of the disease. The genes predisposing to these thoracic aortic diseases are inherited in an autosomal dominant manner, and thirteen genes have been identified to date. As the clinical phenotype associated with each specific gene is defined, the data indicate that the underlying gene dictates associated syndromic features. More importantly, the underlying gene also dictates the aortic disease presentation, the risk for dissection at a given range of aortic diameters, the risk for additional vascular diseases and what specific vascular diseases occur associated with the gene. These results lead to the recommendation that the medical and surgical management of these patients be dictated by the underlying gene, and for patients with mutations in ACTA2, the specific mutation in the gene.

    Hypercoagulable states have been associated with aortic thrombosis. Antiphospholipid syndrome (APS) is one of the commonest types of acquired thrombophilia. We report the case of successful anticoagulation management in an APS patient with mobile thrombi within the aorta. A 58-year-old male patient presented to the emergency department (ED) with right-sided hemiparesis. His first symptoms were noted approximately 12–16 hours before presentation to the ED. Magnetic resonance imaging of the brain showed acute embolic infarction of the left frontal and parietotemporal lobes. Transesophageal echocardiography (TEE) and computed tomography angiography (CTA) demonstrated mobile thrombi attached to the wall of the ascending aorta and aortic arch. The patient was diagnosed with APS based on positivity of anti-beta-2 glycoprotein 1 antibodies, and was initiated on anticoagulation therapy. Repeated TEE and CTA revealed complete resolution of the thrombi after 12 days of treatment; the patient was discharged well. PMID:28042559

    Aortic dissection is the most common fatal condition of the aorta, yet it is often missed on initial clinical presentation. Aortic dissection associated with acute coronary syndrome (ACS) is relatively rare, but if it occurs, it can be diagnostically challenging, and the condition can be fatal. Here we describe a case of aortic dissection presenting as ST-segment elevation myocardial infarction (STEMI) managed via the transradial approach. We describe the current literature on the subject.

    Dilation or aneurysm of the ascending aorta can progress to acute aortic dissection (Thoracic Aortic Aneurysms and Aortic Dissections, TAAD). Mutations in genes encoding TGF-β related proteins (TGFBR1, TGFBR2, FBN1, and SMAD3) cause syndromic and inherited TAAD. SMAD4 mutations are associated with juvenile polyposis (JPS) and a combined JPS-hereditary hemorrhagic telangiectasia (HHT) known as JPS-HHT. A family with JPS-HHT was reported to have aortic root dilation and mitral valve abnormalities. We report on two patients with JPS-HHT with SMAD4 mutations associated with thoracic aortic disease. The first patient, an 11-year-old boy without Marfan syndrome features, had JPS and an apparently de novo SMAD4 mutation (c.1340_1367dup28). Echocardiography showed mild dilation of the aortic annulus and aortic root, and mild dilation of the sinotubular junction and ascending aorta. Computed tomography confirmed aortic dilation and showed small pulmonary arteriovenous malformations (PAVM). The second patient, a 34-year-old woman with colonic polyposis, HHT, and Marfan syndrome, had a SMAD4 mutation (c.1245_1248delCAGA). Echocardiography showed mild aortic root dilation. She also had PAVM and hepatic focal nodular hyperplasia. Her family history was significant for polyposis, HHT, thoracic aortic aneurysm, and dissection and skeletal features of Marfan syndrome in her father. These two cases confirm the association of thoracic aortic disease with JPS-HHT resulting from SMAD4 mutations. We propose that the thoracic aorta should be screened in patients with SMAD4 mutations to prevent untimely death from dissection. This report also confirms that SMAD4 mutations predispose to TAAD.

    Background Congenital aortic valve fusion is associated with aortic dilation, aneurysm and rupture in girls and women with Turner syndrome (TS). Our objective was to characterize aortic valve structure in subjects with TS, and determine the prevalence of aortic dilation and valve dysfunction associated with different types of aortic valves. Methods and Results The aortic valve and thoracic aorta were characterized by cardiovascular magnetic resonance imaging in 208 subjects with TS in an IRB-approved natural history study. Echocardiography was used to measure peak velocities across the aortic valve, and the degree of aortic regurgitation. Four distinct valve morphologies were identified: tricuspid aortic valve (TAV) 64%(n=133), partially fused aortic valve (PF) 12%(n=25), bicuspid aortic valve (BAV) 23%(n=47), and unicuspid aortic valve (UAV) 1%(n=3). Age and body surface area (BSA) were similar in the 4 valve morphology groups. There was a significant trend, independent of age, towards larger BSA-indexed ascending aortic diameters (AADi) with increasing valve fusion. AADi were (mean +/− SD) 16.9 +/− 3.3 mm/m2, 18.3 +/− 3.3 mm/m2, and 19.8 +/− 3.9 mm/m2 (p<0.0001) for TAV, PF and BAV+UAV respectively. PF, BAV, and UAV were significantly associated with mild aortic regurgitation and elevated peak velocities across the aortic valve. Conclusions Aortic valve abnormalities in TS occur with a spectrum of severity, and are associated with aortic root dilation across age groups. Partial fusion of the aortic valve, traditionally regarded as an acquired valve problem, had an equal age distribution and was associated with an increased AADi. PMID:24084490

    2015-06-01

    Outlining specific protocols for the management of pediatric patients with Marfan syndrome has been challenging. This is mostly due to a dearth of clinical studies performed in pediatric patients. In Marfan syndrome, the major sources of morbidity and mortality relate to the cardiovascular system. In this review, we focus on aortic involvement seen in pediatric patients with Marfan syndrome, ranging from aortic dilatation to aortic rupture and heart failure. We discuss the histological, morphological, and pathogenetic basis of the cardiac manifestations seen in pediatric Marfan syndrome and use a specific case to depict our experienced range of cardiovascular manifestations. The survival for patients with Marfan syndrome may approach the expected survival for non-affected patients, with optimal management. With this potentiality in mind, we explore possible and actual management considerations for pediatric Marfan syndrome, examining both medical and surgical therapy modalities that can make the possibility of improved survival a reality.

    The Heimlich maneuver has been widely accepted as a safe and effective method of relieving life-threatening foreign-body upper airway obstruction. When applied incorrectly, however, it may result in direct trauma to the intraabdominal viscera. Only two cases of major aortic complications have been reported. Both have involved thrombosis of an abdominal aortic aneurysm. We report two further instances of aortic thrombotic complications due to the incorrect application of the Heimlich maneuver. The first case resulted in thrombosis of an abdominal aortic aneurysm. In the second case the abdominal thrusts caused dislodgement of thrombus from an atherosclerotic nonaneurysmal aorta, which resulted in thromboembolic occlusion of both lower extremities. In both cases, as with the two previously reported instances, massive reperfusion injury resulted, which eventually proved fatal. When applied incorrectly, the Heimlich maneuver may result in direct trauma to the abdominalaorta and is an unusual cause of acute aortic thrombosis.

    2014-01-01

    Aortic root dilation and propensity to dissection are typical manifestations of the Marfan Syndrome (MS), a genetic defect leading to the degeneration of the elastic fibres. Dilation affects the structure of the flow and, in turn, altered flow may play a role in vessel dilation, generation of aneurysms, and dissection. The aim of the present work is the investigation in-vitro of the fluid dynamic modifications occurring as a consequence of the morphological changes typically induced in the aortic root by MS. A mock-loop reproducing the left ventricle outflow tract and the aortic root was used to measure time resolved velocity maps on a longitudinal symmetry plane of the aortic root. Two dilated model aortas, designed to resemble morphological characteristics typically observed in MS patients, have been compared to a reference, healthy geometry. The aortic model was designed to quantitatively reproduce the change of aortic distensibility caused by MS. Results demonstrate that vorticity released from the valve ...

    Full Text Available A simple emergency risk prediction tool should be developed for clinicians to quickly identify the prognosis of patients with acute aortic dissection.We enrolled 280 patients with acute aortic dissection admitted to emergency department between May 2010 and February 2013. Multivariate logistic regression analysis was performed to identify independent predictors of in-hospital death.The in-hospital mortality of our patients with acute aortic dissection was 32.5%, in-hospital deaths with surgery less than the survived (34.1% VS 54.5%. Multivariate analysis identified that age (≥65 years old, Type A, blood pressure (mean systolic blood pressure ≤ 90 mmHg, neutrophil percentage (≥ 80% and serum D-dimer (≥ 5.0 mg/L were significant predictors of death. With the simple emergency risk prediction tool, scores of all in-hospital deaths were ≥ 3, whereas almost all of the survivors (97.9% had scores < 15. A score of 10 offered the best threshold value, with the highest sensitivity (81.3% and specificity (86.8%.The in-hospital mortality rate of patients with acute aortic dissection is high and can be predicted. Early surgery would be beneficial for in-hospital survive. This tool should be available for clinicians in the emergency department to quickly identify the prognosis of patients with acute aortic dissection.

    There are currently no data on ethnic differences in aortic atherosclerosis in Arab and Jewish patients from northern Israel with acute ischemic stroke. Data on demographic and risk factors alongside transesophageal echocardiography (TEE) data and treatment details for 509 patients with acute ischemic stroke were included in the study. The patients with aortic atheromas were older and had significantly more frequent vascular risk factors (hypertension, hyperlipidemia, and smoking), as well as vascular disease (ischemic heart disease, peripheral vascular disease, and carotid plaques). They were also treated with statins more often than those without aortic atheroma. Logistic regression analysis showed that age, smoking, ethnicity, and the presence of carotid plaques were independent predictors for aortic atheromas. Aortic plaques were found more frequently in Jewish patients than Arab patients (160 (41.9%) vs. 35 (27.3%); p= 0.003). This finding did not change after adjustment for age, sex, all vascular risk factors, and type of antithrombotic treatment. We did not find any difference between Arab and Jewish patients in the distribution of plaques by location or complexity before and after adjustment for age, sex, all vascular risk factors, or type of antithrombotic or lipid-lowering treatment. Our findings emphasize the influence of ethnicity on the prevalence of aortic atheromas in acute ischemic stroke patients in northern Israel. The search for genetic, cultural, socioeconomic, and other factors explaining these ethnic differences should be the topic of future studies.

    Recently, the close relationship between aortic stiffness and cardiovascular mortality has aroused the interest of investigators in carrying out studies related to aortic stiffness. This study aims to investigate the aortic stiffness parameters in patients with cardiac syndrome X, a disorder that is believed to be a generalized disturbance of the vasodilator function of small arteries. 18 patients with typical chest pain and angiographically normal coronary arteries associated with a positive exercise test were included in the study. The control group consisted of 27 patients with angiographically normal coronary arteries and no ischaemia on exercise testing. Antianginal medication was withheld 4 weeks before the study and transthoracic echocardiography was performed using a Hewlett-Packard Sonos 1500 instrument with a 2.5 MHz phased array transducer. Ascending aorta diameters were measured on the M-mode tracing at a level 3 cm above the aortic valve. Diameter change, pulse pressure, aortic strain and distensibility were measured as aortic stiffness parameters. The aortic diameter change was less in the syndrome X group than in the control group (0.15 +/- 0.04 cm/m2 vs. 0.28 +/- 0.12 cm/m2, p < 0.001). Likewise, aortic strain (9 +/- 3% vs. 18 +/- 8%, p < 0.001) and distensibility (4.01 +/- 1.71 cm2 x dyn(-1) x 10(-3) vs. 9.95 +/- 5.08 cm2 x dyn(-1) x 10(-3), p < 0.001) was significantly lower in the syndrome X group than in the control group. The deterioration in aortic elasticity properties in patients with cardiac syndrome X suggests that this disease may be a more generalized disturbance of the vasculature.

    Full Text Available OBJECTIVE: There are debates regarding the optimal approach for AAAD involving the aortic root. We described a modified reinforced aortic root reconstruction approach for treating AAAD involving the aortic root. METHODS: A total of 161 patients with AAAD involving the aortic root were treated by our modified reinforced aortic root reconstruction approach from January 1998 to December 2008. Key features of our modified approach were placement of an autologous pericardial patch in the false lumen, lining of the sinotubular junction lumen with a polyester vascular ring, and wrapping of the vessel with Teflon strips. Outcome measures included post-operative mortality, survival, complications, and level of aortic regurgitation. RESULTS: A total of 161 patients were included in the study (mean age: 43.3 1 15.5 years. The mean duration of follow-up was 5.1 1 2.96 years (2-12 years. A total of 10 (6.2% and 11 (6.8% patients died during hospitalization and during follow-up, respectively. Thirty-one (19.3% patients experienced postoperative complications. The 1-, 3-, 5-, and 10-year survival rates were 99.3%, 98%, 93.8%, and 75.5%, respectively. There were no instances of recurrent aortic dissection, aortic aneurysm, or pseudoaneurysm during the entire study period. The severity of aortic regurgitation dramatically decreased immediately after surgery (from 28.6% to 0% grade 3-4 and thereafter slightly increased (from 0% to 7.2% at 5 years and 9.1% at 10 years. CONCLUSION: This modified reinforced aortic root reconstruction was feasible, safe and durable/effective, as indicated by its low mortality, low postoperative complications and high survival rate.

    Pectus excavatum is generally an isolated abnormality of the chest wall. However, some patients have a concomitant pectus deformity and cardiac & aortic disease. Decisions must be made regarding the operative approach and whether the pectus excavatum should be corrected during the same session. We report 2 patients with acute Stanford type A aortic dissection and pectus excavatum who underwent emergency operation. In case 1, median sternotomy is an unsuitable approach for open heart surgery, since the heart and great vessels are displace into the left hemithorax. But combined sternotomy and left anterior thoracotomy provided excellent surgical exposure. In case 2, we proceeded with a leftsided costotomy of four ribs and place a normal chest retractor providing as excellent exposure as combined sternotomy and left anterior thoracotomy. A left-sided costotomy of four ribs can be performed safely, eliminating the risks of median sternotomy in acute stanford type A aortic dissection with pectus excavatum.

    We report a patient who presented with severe nephrotic syndrome complicated with infrarenal aortic and right renal arterial thrombosis. The nephrotic syndrome frequently causes thromboembolic complications in veins, but arterial thrombosis is relatively rare, especially in the aorta. Various predisposing factors leading to thromboembolic complications are discussed. In this case, the thromboembolic complication may have some clinical association with the hypercoagulable state in nephrotic syndrome.

    Full Text Available There are many genetic syndromes associated with the aortic aneurysmal disease which include Marfan syndrome (MFS, Ehlers-Danlos syndrome (EDS, Loeys-Dietz syndrome (LDS, familial thoracic aortic aneurysms and dissections (TAAD, bicuspid aortic valve disease (BAV, and autosomal dominant polycystic kidney disease (ADPKD. In the absence of familial history and other clinical findings, the proportion of thoracic and abdominal aortic aneurysms and dissections resulting from a genetic predisposition is still unknown. In this study, we propose the review of the current genetic knowledge in the aortic disease, observing, in the results that the causative genes and molecular pathways involved in the pathophysiology of aortic aneurysm disease remain undiscovered and continue to be an area of intensive research.

    Marfan's syndrome is a hereditary connective tissue disease, in which cardiovascular abnormalities (especially aortic root dilatation) are the most important cause of morbidity and mortality. In this report, we describe two 24-year-old twins, with a history of surgery for lens subluxation and severe cardiovascular manifestations secondary to Marfan's syndrome. One of the twins suffered a type A aortic dissection, which required replacement of the ascending aorta, and the other twin had an aneurysmal dilatation of the ascending aorta (46mm) and was prescribed medical treatment with atenolol and periodic controls to detect the presence of a critical diameter (50mm) that would indicate the need for prophylactic surgery.

    Surgical treatment poses a high risk to patients with concomitant aortic coarctation and dissection, and an interventional approach could be an alternative. We describe the case of a 52-year-old man with a long history of untreated hypertension and aortic coarctation who emergently presented at our institution with an acute Stanford type B dissection. The patient's elevated serum creatinine level, perfusion deficit in the right lower limb, and hypertension did not respond to medical therapy, and he did not consent to surgery. By endovascular means, we used a self-expandable stent-graft to cover the entry point of the dissection; then, we deployed a balloon-expandable bare-metal stent to correct residual stenosis. To our knowledge, this is the first report of the endovascular treatment of aortic coarctation complicated by type B dissection.

    Intraoperative Type A aortic dissection is a rare pathology with incidence of 0.06-0.32%. It is associated with a high mortality between 30-50%. Some associated risk factors, including hypertension, enlarged aorta, peripheral vascular disease, advanced age, atheroma, and high arterial pressure on cardiopulmonary bypass, have been identified. Modification of these risk factors could reduce the incidence of this event. Prompt diagnosis and management, with the aid of intraoperative trans-esophageal echocardiography and/or epi-aortic ultrasound has been shown to reduce the mortality to 17%. We illustrate the principles of management of this pathology with the case of a 62-year-old female who developed acute Type A aortic dissection while undergoing minimally invasive mitral valve repair.

    2015-01-01

    acute compartment syndrome (ACS) is one of the few true emergencies in orthopedics and traumatology. It is a painful condition caused by the increase interstitial pressure (intracompart-mental pressure - ICP) within a closed osteofascial compartment which impair local circulation. It occurs most often in the legs, but it can affects also the arms, hands, feet, and buttocks. It usually develops after a severe injury such as fractures or crush injury, but it can also occurs after a relatively minor injury and it may be iatrogenic. Uncommon causes of ACS have been also described, that suggest surgeons to pay great attention to this serious complication. Diagnosing ACS is difficult in clinical practice, even among expert surgeons. Currently, the diagnosis is made on the basis of physical examination and repeated ICP measures. ICP higher than 30 mmHg of diastolic blood pressure is significant of compartment syndrome. Once diagnosis is made, fasciotomy to release the affected compartment should be performed as early as possible because delayed decompression would lead to irreversible ischemic damage to muscles and peripheral nerves. acute compartment syndrome is a surgical emergency. There is still little consensus among authors about diagnosis and treatment of these serious condition, in particular about the ICP at which fasciotomy is absolutely indicated and the timing of wound closure. New investigations are needed in order to improve diagnosis and treatment of ACS.

    "Seat belt syndrome" was first described by Garret and Braunstein in 1962. The syndrome involves skin and abdominal wall ecchymosis (seat belt sign) intra-abdominal solid organ and visceral injuries, as well as Chance fractures (compression and/or wedging deformity of the anterior portion of the vertebral body with disruption or fracture of the posterior elements, generally at L1-L3). We present a case of a 12-year-old male involved in a high-speed motor vehicle collision wearing only a lap belt resulting in seat belt syndrome, with disruption of the abdominal wall, mesenteric avulsion with multiple intestinal perforations, abdominal aortic dissection, and an L2 Chance fracture with cord transection. Intraoperative decision making is outlined with this scenario of complex injuries, and the literature of seat belt syndrome associated with blunt aortic injuries and its management is reviewed.

    Aortic size index (ASI) has been proposed as a reliable criterion to predict risk for aortic dissection in Turner syndrome with significant thresholds of 20-25 mm/m2. We report a case of aortic arch dissection in a patient with Turner syndrome who, from the ASI thresholds proposed, was deemed to be at low risk of aortic dissection or rupture and was not eligible for prophylactic surgery. This case report strongly supports careful monitoring and surgical evaluation even when the ASI is < 20 mm/m2 if other significant risk factors are present. PMID:24944765

    Objective Marfan syndrome patients with aortic root aneurysms undergo elective aortic root replacement to avoid the life-threatening outcomes of aortic dissection and emergency repair. The long-term implications of failed aortic surveillance leading to acute dissection and emergency repair are poorly defined. We compared the long-term clinical courses of Marfan syndrome patients who survive emergency versus elective proximal aortic surgery. Methods The GenTAC Registry is an NIH-funded, multicenter database and biorepository that enrolls patients with genetically triggered thoracic aortic aneurysms. Of the 635 patients with Marfan syndrome enrolled as of March 2011, 194 had undergone proximal aortic replacement. Patients were grouped according to emergent (n=47) or elective (n=147) status at the time of surgery. Results Patients in the emergent group were more likely to have incomplete proximal aortic resection; 83% of emergency procedures included aortic root replacement, compared with 95% of elective procedures. At long-term follow-up (mean, >6 years), emergent patients had a higher incidence of chronic dissection of the distal aorta and had significantly larger diameters in distal aortic segments than elective patients. Additionally, emergent patients had undergone more operations (1.31 vs 1.11 procedures/patient; P=0.01) and had lower activity scores on a health-related quality-of-life survey. Conclusions For Marfan syndrome patients, failed aortic surveillance and consequent emergency dissection repair have important long-term implications with regard to status of the distal aorta, the need for multiple procedures, and quality of life. These findings emphasize the importance of aortic surveillance and timely elective aortic root aneurysm repair for Marfan syndrome patients. PMID:22104675

    Full Text Available We report a rare case of acute right coronary artery stenosis developing in a patient undergoing aortic valve replacement. We present a case report with a brief overview of the literature relating to coronary artery occlusion associated with cardiac valve surgery - the theories and treatments are discussed. A 85 year-old female was admitted under the care of the cardiothoracic team with signs and symptoms of heart failure. Investigations, including cardiac echocardiography and coronary angiography, indicated a critical aortic valve stenosis. Intraoperative right ventricular failure ensued post aortic valve replacement. Subsequent investigations revealed an acute occlusion of the proximal right coronary artery with resultant absence of distal flow supplying the right ventricle. An immediate right coronary artery bypass procedure was performed with resolution of the right ventricular failure. Subsequent weaning off cardiopulmonary bypass was uneventful and the patient continued to make excellent recovery in the postoperative phase. To our knowledge this is one of the few documented cases of intraoperative acute coronary artery occlusion developing during valve surgery. However, surgeons should be aware of the potential for acute occlusion so that early recognition and rapid intervention can be instituted.

    Acute type A aortic dissection frequently induces aortic root disease; however, the optimal surgical strategy for aortic root dissection remains a challenge. The objective of this study was to introduce a novel technique for reconstruction of type A dissection to improve patient prognosis. We performed a retrospective review of 791 consecutive patients with acute type A aortic dissection between January 2003 and July 2015. Among these patients, 151 were selected (72% men, age 51.7 ± 9.8 years) to have the modified sandwich repair of aortic root dissection. The in-hospital mortality rate of the 151 patients was 6.6% (10/151). During a mean follow-up period of 52.7 ± 28.6 months, the survival rate was 100, 89.1 and 69.7% at 1, 5 and 10 years, respectively. Echocardiography and computed tomographic angiography were performed every year to monitor the pathological change in the aortic root. Freedom from severe aortic regurgitation at 5 years was 100%. No patients required reintervention due to dissection or pseudoaneurysm of the proximal aortic root. Aortic valve resuspension and repair of the sinus of Valsalva with the modified sandwich technique using Teflon felt strips for acute type A dissection could be reliable and effective.

    Congenital aortic valve anomalies are the cause of premature aortic stenosis in pediatric and younger adult populations. Despite being very rare, unicuspid aortic valves account for approximately 5% of isolated aortic valve replacements. Patients with aortic stenosis, present with the same symptomatology independent of leaflet morphology. However, the presence of bicuspid and unicuspid aortic stenosis is associated with a higher incidence of aortopathy, especially in Turner syndrome patients. Turner syndrome, an X monosomy, is associated with aortic valve anomalies, aortopathy, and hypertension. These risk factors lead to a higher incidence of aortic dissection in this population. Patients with Turner syndrome and aortic stenosis that present for aortic valve replacement should therefore undergo extensive aortic imaging prior to surgery. Transthoracic echocardiography is the diagnostic tool of choice for valvular pathology, yet it can misdiagnose unicuspid aortic valves as bicuspid valves due to certain similarities on imaging. Transesophageal echocardiography is a better tool for distinguishing between the two valvular abnormalities, although diagnostic errors can still occur. We present a case of a 50-year-old female with history of Turner syndrome and bicuspid aortic stenosis presenting for aortic valve replacement and ascending aorta replacement. Intraoperative transesophageal echocardiography revealed a stenotic unicommissural unicuspid aortic valve with an eccentric orifice, which was missed on preoperative imaging. This case highlights the importance of intraoperative transesophageal echocardiography in confirming preoperative findings, diagnosing further cardiac pathology, and ensuring adequate surgical repair.

    2014-09-01

    Full Text Available Acute type A aortic dissection has long been a challenging issue. The surgical techniques traditionally vary with the anatomic extent of the aortic dissection. Simple ascending aortic grafting can be lifesaving, but the lesions beyond the aorta, which include the arch vessels and descending aorta, remain potential hazards. In this paper, we present a patient in which acute type A aortic dissection with lesions extending into descending thoracic aorta was successfully managed by total arch replacement with supra-aortic transposition plus the frozen elephant trunk technique to the descending aorta. A 67-year-old gentleman presented with severe tearing pain from the anterior to posterior chest. Computed tomography confirmed the diagnosis of acute type A dissection extending to the level of the right common iliac artery. An emergent operation was performed as in the aforementioned technique. The surgery went well and the patient was discharged without comorbidities on postoperative day 25. The patient had regular outpatient clinical follow-up. The follow-up computed tomography images showed adequate results with the obliteration of the false lumen. In conclusion, total aortic arch replacement with supra-aortic transposition plus frozen elephant trunk technique is a safe and feasible operative method for patients with detrimental acute type A aortic dissection.

    The acute coronary syndrome is the most severe form of coronary artery disease. It is an immediate threat of life and the mortality rate can be high without proper therapy and patient management. Based on the first ECG, two different forms can be distinguished: acute coronary syndrome with and without ST elevation. Besides adequate medication, management of these patients is an essential part of treatment. In case of ST elevation, coronarography and percutaneous coronary intervention is needed in general, within 24 hours from the onset of symptoms. When ST elevation is not detected on the ECG, individual ischemic risk factors and predictable mortality of the patient may define the necessity and the date of the invasive examination. The Hungarian hemodynamic laboratory network covers almost the whole country and, therefore, practically each patient may receive a state-of-the-art therapy. Although indicators of cardiovascular diseases are still prominent, the mortality rate of myocardial Infarction is decreasing in Hungary due to the well-organized invasive care.

    In this overview we aim to address a number of recent insights and developments regarding clinical aspects, etiology, and treatment of Heritable Thoracic Aortic Disease (H-TAD). We will focus on monogenetic disorders related to aortic aneurysms. H-TADs are rare but they provide a unique basis for the study of underlying pathogenetic pathways in the complex disease process of aneurysm formation. The understanding of pathomechanisms may help us to identify medical treatment targets to improve prognosis. Among the monogenetic aneurysm disorders, Marfan syndrome is considered as a paradigm entity and many insights are derived from the study of clinical, genetic and animal models for Marfan syndrome. We will therefore first provide a detailed overview of the various aspects of Marfan syndrome after which we will give an overview of related H-TAD entities.

    The Marfan syndrome (MFS) is a systemic connective tissue disorder caused by mutations in the FBN1 gene.Recent molecular studies,most performed in mouse models,revealed that the MFS is more a developmental abnormality with broad and complex effects on the morphogenesis and function of multiple organ systems.FBN1 haploinsufficiency and dysregulated transforming growth factor-beta (TGF-β)signaling seem to be critical for clinical manifestations in MFS including aortic root dilatation.Aortic root aneurysm and aortic dissection represent the main causes of morbidity and mortality in MFS.Most importantly,TGF-β antagonism through angiotensin Ⅱ type 1 receptor blockers (ARBs),for example losartan,has been shown to prevent and possibly reverse aortic root dilatation in a mouse model of MFS.A first human study on a small pediatric cohort confirmed those promising results in reducing the aortic root growth over a follow-up period of 12 to 47 months.So,a large multicenter trial has been set up and results should be available soon.Other therapeutic strategies which might be combined with losartan include traditional β-blockade,doxycyclin and statins.Such management could offer the first potential for primary prevention of clinical manifestations in MFS.

    The formation of aortic thrombi is an extremely rare complication of acute pancreatitis. Here we report a case of acute pancreatitis complicated by a paraesophageal pseudocyst, necrotizing mediastinitis, and the formation of multiple thrombi in the ascending aorta. The patient was successfully treated by surgical therapy, which included extensive debridement of the mediastinum and removal of the aortic thrombi under cardiopulmonary bypass. Although esophageal resection was not carried out concomitantly, the lesions were resolved and the patient remained free of complications over 2 years of follow-up care. PMID:27734004

    Aortic dissection is a critical but rare complication of Turner syndrome. This report describes a case of chronic aortic dissection in a patient with Turner syndrome. A 54-year-old woman, suffering from mild back pain for 1 month, was referred to our hospital with a diagnosis of Stanford type A chronic aortic dissection and a bicuspid aortic valve with moderate regurgitation. Computed tomography revealed aortic dissection, involving all arch branches, extending from the ascending to the abdominal aorta. The true lumen of the brachial artery was nearly obstructed by the thrombosed false lumen. Elective aortic arch repair and aortic valve replacement were successfully performed. The patient was diagnosed with 45, XO Turner syndrome after surgery. Taking aortopathy of Turner syndrome into consideration, surveillance of the residual aorta was performed. No rapidly progressive dilatation of the residual aorta was detected during the 6 years' follow-up.

    PURPOSE: Depression is common following acute coronary syndrome, and thus, it is important to provide knowledge to improve prevention and detection of depression in this patient group. The objectives of this study were to examine: (1) whether indicators of stressors and coping resources were risk...... factors for developing depression early and later after an acute coronary syndrome and (2) whether prior depression modified these associations. METHODS: The study was a register-based cohort study, which includes 87,118 patients with a first time diagnosis of acute coronary syndrome during the period.......8 % developed a recurrent depression. Most patient characteristics (demographic factors, socioeconomic status, psychosocial factors, health-related behavioural factors, somatic comorbidities, and severity of acute coronary syndrome) were significantly associated with increased HRs for both early and later...

He underwent successful removal of the thrombus combined with mechanical replacement of the aortic valve.

  14. Acute aortic dissection in patient with suspected pheochromocytoma

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Introduction: Aortic dissection is one of the most fatal vascular emergencies. Almost 40% of the patients do not reach hospital in time while more than quarter die in the first 24 hours after the dissection begins. Case Report: A 37-year old man was admitted to our hospital with severe anterior chest pain which had lasted for over a week. Suspected aortic dissection was rapidly confirmed using imaging modalities - MDCT chest scan and TTE, followed by an urgent surgical management - Bentall procedure. MDCT chest scan also discovered adrenal incidentaloma defined as malignant, pheochromocytoma like mass. Due to the critical state of the patient, there was not enough time for further endocrinologic testing. Discussion and conclusion: When treating patients with pheochromocytoma and acute aortic disection, it is crucial to obtain a stable hemodynamic state before the surgery, since they can trigger a severe hypertensive crisis due to high levels of cathecholamines induced chronic vasoconctriction. The most vulnerable periods are the induction of anesthesia and perioperative hemodynamic oscillations, so treating patients with short acting alpha- 1 adrenergic blocking agents preoperatively has proven to be helpful - Phentolamine. Both dissection of aorta and pheochromocytoma present challenges for anesthesiologists and early recognition of symptoms is essential in establishing the diagnosis and reducing the mortality rate.

    2012-01-01

    Full Text Available This paper, based on relevant literature articles and the authors' clinical experience, presents a goal-oriented respiratory management for critically ill patients with acute respiratory distress syndrome (ARDS that can help improve clinicians' ability to care for these patients. Early recognition of ARDS modified risk factors and avoidance of aggravating factors during hospital stay such as nonprotective mechanical ventilation, multiple blood products transfusions, positive fluid balance, ventilator-associated pneumonia, and gastric aspiration can help decrease its incidence. An early extensive clinical, laboratory, and imaging evaluation of “at risk patients” allows a correct diagnosis of ARDS, assessment of comorbidities, and calculation of prognostic indices, so that a careful treatment can be planned. Rapid administration of antibiotics and resuscitative measures in case of sepsis and septic shock associated with protective ventilatory strategies and early short-term paralysis associated with differential ventilatory techniques (recruitment maneuvers with adequate positive end-expiratory pressure titration, prone position, and new extracorporeal membrane oxygenation techniques in severe ARDS can help improve its prognosis. Revaluation of ARDS patients on the third day of evolution (Sequential Organ Failure Assessment (SOFA, biomarkers and response to infection therapy allows changes in the initial treatment plans and can help decrease ARDS mortality.

    1992-09-01

    We report on a 24 + 2 weeks pregnant woman with Marfan's syndrome, who acutely developed a dissecting aortic aneurysm with aortic valve insufficiency. Emergency surgery was performed by using hypothermic extracorporeal circulation, whilst the aortic valve and ascending aorta were replaced by a synthetic graft. Foetal heart rates, continuously monitored by using Doppler ultrasound, were shown to be closely correlated with perfusion pressures. By applying perfusion pressures of 90-100 mmHg, we were able to maintain foetal heart rates of approximately 100/min. During the first postoperative day, the CTG was normal for gestational age and no contractions were noted. During the second postoperative night, the patient prematurely delivered a dead 820 g infant (Apgar score 0/0/0/0). In view of this case report, opportunities and problems associated with an application of extracorporeal circulation during pregnancy are discussed.

    Acute thrombotic or embolic occlusion of the abdominal aorta is a rare vascular emergency associated with high morbidity and mortality rates. Classically, the clinical presentation is a severe peripheral ischemia with bilateral leg pain as the predominant feature. Aortic occlusion presenting as an isolated acute onset of paraplegia due to spinal cord ischemia is very rare and requires improved awareness to prevent adverse outcomes associated with delayed diagnosis. We report the case of a 54-year-old man who presented with sudden paraplegia due to the thrombotic occlusion of the infrarenal aorta involving the first segment of the common iliac arteries on both sides; emergent transperitoneal aorto iliac thrombectomy combined with the endovascular iliac kissing-stent technique were performed achieving perioperative complete regression of the symptoms.

    Full Text Available A 60 year old male patient presented with hoarseness of voice lasting for 2 months. First he was examined by the otorhinolaryngologist of our hospital, who noticed absence of movements of the left vocal cord. Chest X-ray showed a large opacity in the left upper zone and the patient was referred to the pulmonologist. His general physical examination was unremarkable not having any stigmata of Marfan's or Ehler Danlos syndrome. On chest auscultation, a systolic flow murmur was audible and there was decreased breath sound in the left infraclavicular area. Bronchoscopy revealed absence of movement of left vocal cord. His trans-thoracic echocardiography revealed degenerative aortic and mitral valve disease with mild aortic regurgitation and mild mitral regurgitation with dilated aortic aneurysm. A contrast enhanced CT scan of thorax and CT Angio Aortogram revealed fusiform aneurysmal dilatation of the arch of aorta with diameter of 6.2 cm over a length of 12.3 cm showing intraluminal partial thrombus with wall calcification. The patient was advised to undergo surgery. However, after detailed discussion with him and his family, they decided for medical management in view of his advanced age

    Despite limited data, the necessity for immediate surgical intervention in octogenarians with acute type A aortic dissection (AAD) has recently been questioned because the surgical risk may outweigh its potential benefits. At the same time, evolving stent graft technologies are pushing in the market for pathology within the ascending aorta, even for treatment of AAD. Against this background, we analyzed our institutional experience in this patient cohort during the last 8 years. Between October 2005 and October 2013, 39 patients aged older than 80 years (82 ± 2 years) underwent surgical repair for AAD, of which 29 patients (74%) were men. Owing to patient age and comorbidities, we aimed to limit the operation to supracoronary hemiarch replacement whenever possible. Clinical data were prospectively entered into our institutional database. Late follow-up was 3.6 ± 2.8 years and was 100% complete. Hemiarch replacement was performed in 32 patients (82%), and full arch replacement was necessary in the remaining 7. In 31 patients (79%), the aortic root could be glued and reconstructed or remained untouched. The remaining 8 patients (21%) underwent the bio-Bentall procedure. Mean ventilation time was 46 ± 23 hours, and the intensive care unit stay was 5 ± 9 days. We observed new postoperative permanent neurologic deficits in 2 patients (5%) and transient neurologic deficits in 3 (8%). The 30-day mortality was 26% (n = 10). Kaplan-Meier estimates for late survival were 46% ± 16% at 5 years. Given the guidelines regarding the predicted risk of death in patients with untreated AAD, current data suggest a survival benefit with immediate open surgical intervention even in octogenarians. Similarly to the early days of transcatheter-based aortic valve implantation, open surgical reference data are warranted to set the bar for upcoming endovascular treatment of AAD in octogenarians.

    Long-term CT follow-up studies are required in pediatric patients who have received intraoperative radiation therapy (IORT) and external beam radiation therapy (EBRT) to assess vascular toxicities and to determine the exact complication rate. To analyze with CT the effects of radiation therapy (RT) on the growth of the aorta in neuroblastoma patients. Abdominal CT scans of 31 patients with intraabdominal neuroblastoma (stage II-IV), treated with RT (20 IORT{+-}EBRT, 11 EBRT alone), were analyzed retrospectively. The diameter of the abdominal aorta was measured before and after RT. These data were compared to normal and predicted normal aortic diameters of children, according to the model of Fitzgerald, Donaldson and Poznanski (aortic diameter in centimeters = 0.844+0.0599 x age in years), and to the diameters of a control group of children who had not undergone RT. Statistical analyses for the primary aims were performed using the chi-squared test, t-test, Mann-Whitney test, nonparametric Wilcoxon matched-pairs test and analysis of variance for repeated measures. Clinical files and imaging studies were evaluated for signs of late vascular complications of neuroblastoma patients who had received RT. The mean diameter before and after RT and the growth of the aorta were significantly lower than expected in patients with neuroblastoma (P<0.05 for each) and when compared to the growth in a control group with normal and nonirradiated aortas. Among the patients who had received RT, there was no difference due to the type of RT. Seven patients from the IORT{+-}EBRT group developed vascular complications, which included hypertension (five), middle aortic syndrome (two), death due to mesenteric ischemia (one) and critical aortic stenosis, which required aortic bypass surgery (two). Patients with neuroblastoma who had received RT showed impaired growth of the abdominal aorta. Significant long-term vascular complications occurred in seven patients who received IORT

    Penetrating atheromatous ulcer (PAU) is an atherosclerotic ulcer penetrating the internal elastic lamina of the aortic wall causing a hematoma within the media layer of aorta. They are commonly located in the descending aorta of the elderly and hypertensive patients. They may rarely be complicated by aortic dissection. We report a relative young normotensive patient presenting with acute aortic dissection due to PAU located in the ascending aorta.

    Abstract Thoracic endovascular aortic repair (TEVAR) in the current era has been chosen as a dominant and minimally invasive treatment for complicated aorta dissection. This study aimed to assess safety and feasibility of TEVAR in acute and chronic type B aortic dissection. Between January 2011 and December 2013, 85 patients with complicated type B aortic dissection undergoing TEVAR were divided into acute aortic dissection (AAD) (n = 60) group and chronic aortic dissection (CAD) group (n = 25). Computed tomography was used to evaluate postoperative changes in maximal aortic diameter and true and false lumen diameters at 3 levels during a mean follow-up period of 26.4 ± 15.6 months. The technical success rate was 100%. In-hospital and 30-day rates of death were 3.3% in acute group and 0 in chronic group. Postdischarge rates of type I leak, type II leak, and retrograde type A dissection were 6.7%, 5.2%, and 3.4% (acute) and 0%, 4.0%, and 4.0% (chronic), respectively. The maximal aorta diameter remained stable in all the 3 levels in both acute and chronic group. The cumulative freedom from all-cause mortality at 3 years was similar in acute and chronic groups (89.5% vs 95.5%, P = .308). The cumulative freedom from aortic-related mortality was also not significantly different in the acute and chronic groups (92.8% vs 95.2%, P = .531). In the thoracic aorta, TEVAR treatment resulted in a significant increase in true lumen (TL) diameter and decrease in false lumen (FL). However, in the abdominal aorta, TEVAR did not lead to significant change in TL and FL diameters. The rates of complete thrombosis thoracic false lumens were better than that in the abdominal false lumen. TEVAR was a safe and effect therapy for complicated acute and chronic type B dissection with low early and mid-term mortality and morbidity. PMID:28700467

    Gene mutations that lead to decreased contraction of vascular smooth-muscle cells (SMCs) can cause inherited thoracic aortic aneurysms and dissections. Exome sequencing of distant relatives affected by thoracic aortic disease and subsequent Sanger sequencing of additional probands with familial thoracic aortic disease identified the same rare variant, PRKG1 c.530G>A (p.Arg177Gln), in four families. This mutation segregated with aortic disease in these families with a combined two-point LOD score of 7.88. The majority of affected individuals presented with acute aortic dissections (63%) at relatively young ages (mean 31 years, range 17-51 years). PRKG1 encodes type I cGMP-dependent protein kinase (PKG-1), which is activated upon binding of cGMP and controls SMC relaxation. Although the p.Arg177Gln alteration disrupts binding to the high-affinity cGMP binding site within the regulatory domain, the altered PKG-1 is constitutively active even in the absence of cGMP. The increased PKG-1 activity leads to decreased phosphorylation of the myosin regulatory light chain in fibroblasts and is predicted to cause decreased contraction of vascular SMCs. Thus, identification of a gain-of-function mutation in PRKG1 as a cause of thoracic aortic disease provides further evidence that proper SMC contractile function is critical for maintaining the integrity of the thoracic aorta throughout a lifetime.

    Acute radiation syndrome (ARS) or sickness or poisoning or toxicity is induced after a whole body exposure of men to high doses of radiation between 1-12Gy. First symptoms are from the gastrointestinal system, which together with bone marrow are the most sensitive parts of our body. Chronic radiation syndrome (CRS) may be induced by smaller than 1Gy radiation doses or after a mild form of ARS. Prophylaxis and treatment suggestions are described. In cases of ARS, a large part of the exposed population after proper medical care may survive, while without medical care this part of the population will be lost. Prophylaxis may also save another part of the population.

    We report the case of a 45-year-old chronic smoker who presented with acute paraplegia occurring during coitus and subsequently developed acute renal failure (ARF) requiring dialysis. He had absent peripheral pulses in the lower limbs with evidence of acute ischemia. Doppler study showed dissecting aneurysm of thoracic aorta, thrombotic occlusion of the distal aorta from L1 level up to bifurcation and occlusion of the right renal artery by a thrombus that was confirmed by magnetic resonance imaging of the spine. He was not subjected to any vascular intervention as his lower limbs were not salvageable due to delay in the diagnosis. Post-coital aortic dissection and aortic dissection presenting with acute paraplegia and ARF are very rare. This is probably the first case report with post-coital acute aortic dissection presenting with paraplegia and ARF. This case emphasizes the importance of a careful examination of peripheral pulses in patients presenting with ARF and paraplegia.

    2016-05-01

    We describe the case of a 28-year old man with Marfan's syndrome and severe pectus excavatum who required an aortic root replacement for an ascending aortic aneurysm. There was a near-vertical angulation of the sternum that presented challenges with opening and exposure of the heart during aortic surgery. Furthermore, removal of the sternal retractor after aortic repair resulted in sudden loss of cardiac output. A Ravitch procedure was then performed to successfully close the chest without further cardiovascular compromise. We propose that patients with a severe pectus excavatum and mediastinal displacement seen on preoperative CT scanning should be considered for simultaneous, elective repair.

    Thoracic aortic dissection is the most frequent cause of aortic emergency, and unless it is rapidly diagnosed and treated, the result is death. Helical computed tomography (CT) permits the diagnosis of acute aortic dissection with a sensitivity and specificity of nearly 100%. This imaging modality also enables differentiation between proximal aortic dissection (type A in the Stanford classification) and distal aortic dissection (Stanford type B), which are treated differently and have different prognoses. In 70% of patients in whom nontraumatic acute thoracic aortic dissection is diagnosed after evaluation with helical CT, scans show the typical signs of aortic dissection, with rupture and displacement of the intima. CT also can depict other pathologic entities with similar clinical manifestations, such as intramural hematoma and penetrating atherosclerotic ulcer. Awareness of the different radiologic appearances of these disease entities is essential for differential diagnosis. More than one-third of patients with aortic dissection show signs and symptoms indicative of systemic involvement. Because branch-vessel involvement may increase morbidity and mortality, in this group of patients it is important to evaluate the entire aorta so as to determine the distal extent of the dissection and detect any systemic involvement.

    Penetrating atherosclerotic aortic ulcer is a rare entity with poor prognosis in the setting of acute aortic syndrome. In the literature, cases like the present one, located in the aortic arch, starting with chest pain and evolving with dysphonia, are even rarer. The present report emphasizes the role played by computed tomography in the diagnosis of penetrating atherosclerotic ulcer as well as in the differentiation of this condition from other acute aortic syndromes. Additionally, the authors describe a new therapeutic approach represented by a hybrid endovascular surgical procedure for treatment of the disease. (author)

    Aortoduodenal syndrome is a rare complication of an abdominal aortic aneurysm wherein the aneurysm sac obstructs the patient\\'s duodenum. It presents with the symptoms of an upper gastrointestinal tract obstruction and requires surgical intervention to relieve it. Previously, gastric bypass surgery was advocated, but now aortic replacement is the mainstay of treatment. We report a case of a 67-year-old woman whose aortoduodenal syndrome was successfully managed and review the literature on this topic.

    Full Text Available Abstract Background Transcatheter aortic valve implantation (TAVI is a promising therapy for patients with severe aortic stenosis (AS and high perioperative risk. New echocardiographic methods, including 2D Strain analysis, allow the more accurate measurement of left ventricular (LV systolic function. The goal of this study was to describe the course of LV reverse remodelling immediately after TAVI in a broad spectrum of patients with symptomatic severe aortic valve stenosis. Methods Thirty consecutive patients with symptomatic aortic valve stenosis and preserved LVEF underwent transfemoral aortic valve implantation. We performed echocardiography at baseline and one week after TAVI. Echocardiography included standard 2D and Doppler analysis of global systolic and diastolic function as well as 2D Strain measurements of longitudinal, radial and circumferential LV motion and Tissue Doppler echocardiography. Results The baseline biplane LVEF was 57 ± 8.2%, the mean pressure gradient was 46.8 ± 17.2 mmHg and the mean valve area was 0.73 ± 0.27 cm2. The average global longitudinal 2D strain of the left ventricle improved significantly from -15.1 (± 3.0 to -17.5 (± 2.4 % (p Conclusion There is an acute improvement of myocardial longitudinal systolic function of the basal and medial segments measured by 2D Strain analysis immediately after TAVI. The radial, circumferential strain and LVEF does not change significantly in all patients acutely after TAVI. These data suggest that sensitive new echo methods can reliably detect early regional changes of myocardial function after TAVI before benefits in LVEF are detectable.

    Aortic dilatation and dissection are rare but important complications of Turner syndrome that increase the risk of sudden death in young patients. To assess the value of aortic MRI in patients with Turner syndrome; in particular to demonstrate early aortic dilatation. A total of 21 patients with Turner syndrome underwent MRI of the thoracic aorta with measurement of vessel diameter at four levels. Measurements were normal for age in 15 cases, two patients presented with values at the upper limit of normal and four had obvious dilatation of the ascending aorta. All were symptom free. MRI allows the non-invasive demonstration of early aortic dilatation, which may lead to earlier surgery in asymptomatic individuals. (orig.)

    Full Text Available Abstract Acute aortic type A dissection is a life-threatening disease that requires immediate surgical intervention. When dissection occurs during pregnancy, it is of high risk for both the mother and the fetus. In this study, we reported two cases of acute aortic dissection in late pregnancy at 28 weeks and 32 weeks of gestation respectively. After the two patients underwent a cesarean section and delivered a baby, we performed composite graft replacement of the aortic valve, aortic root and ascending aorta, with re-implantation of the coronary arteries into the graft (Bentall procedure instead of repairing the arch with deep hypothermia and circulation arrest. Both mothers and children survived and recovered well.

    all species that we work with? What do we define as acute onset? Most human ARDS cases occur while patients are in hospital being treated for other problems, whereas many of our patients present already in respiratory distress. If we are unable to ventilate patients for economic or practical reasons, what do we use as the equivalent of the Pao2/Flo, ratio'? Reliance on the pathologist is not reasonable, because many disease processes can look similar to ARDS under the microscope. If anything, ALI and ARDS are clinical diagnoses. It is time for veterinarians to reach a consensus on the definition for ALI and ARDS in our patients. Only when we have a consensus of definition can rational prospective clinical trials of therapies be designed.

    A 41-year-old man collapsed after lifting weights at a gym. Following admission to the emergency department, a 64-slice cardiac computed tomography (CT) revealed a Stanford Type A aortic dissection arising from a previous coarctation repair. Multiphasic reconstructions demonstrated an unstable, highly mobile aortic dissection flap that extended proximally to involve the right coronary artery ostium. Our case is an example of the application of electrocardiogram-gated cardiac CT in directly visualizing involvement of the coronary ostia in acute aortic dissection, which may influence surgical management.

    Acute aortic regurgitation (AR) post-chronic aortic stenosis is a prevalent phenomenon occurring in patients who undergo transcatheter aortic valve replacement (TAVR) surgery. The objective of this work was to characterize the effects of left ventricular diastolic stiffness (LVDS) and AR severity on LV performance. Three LVDS models were inserted into a physiological left heart simulator. AR severity was parametrically varied through four levels (ranging from trace to moderate) and compared with a competent aortic valve. Hemodynamic metrics such as average diastolic pressures (DP) and reduction in transmitral flow were measured. AR index was calculated as a function of AR severity and LVDS, and the work required to make up for lost volume due to AR was estimated. In the presence of trace AR, higher LVDS had up to a threefold reduction in transmitral flow (13% compared with 3.5%) and a significant increase in DP (2-fold). The AR index ranged from ∼42 to 16 (no AR to moderate AR), with stiffer LVs having lower values. To compensate for lost volume due to AR, the low, medium, and high LVDS models were found to require 5.1, 5.5, and 6.6 times more work, respectively. This work shows that the LVDS has a significant effect on the LV performance in the presence of AR. Therefore, the LVDS of potential TAVR patients should be assessed to gain an initial indication of their ability to tolerate post-procedural AR.

    Between December 2009 and August 2011, 120 patients with uncomplicated Stanford type B acute aortic dissection( UBAD) received medical treatment. In October 2010, we initiated an early rehabilitation program for UBAD patients in an acute phase. This early rehabilitation program, which was aimed at enabling the patient to walk around the ward within 2 days, was conducted for 87 consecutive patients;the remaining 33 were subjected to the conventional rehabilitation program. Mortality was not significantly different between the 2 groups. The incidence of atelectasis, need for mechanical ventilation, and intensive care unit syndrome during medical treatment occurred in 48% (16/33), 15% ( 5/33), and 30% ( 10/33), respectively, of the conventional group and in 3.4% ( 3/87), 1.1% (1/87), and 3.4% ( 3/87), respectively, of the early rehabilitation group. The outer diameter of the aorta was dilated after 4 weeks' rehabilitation in smaller percentage of patients in the early rehabilitation group than the conventional one. Thus, the early rehabilitation program was more effective for patients with UBAD than the conventional one.

He was successfully treated with emergency double valve replacement using mechanical valves. The pathogenesis of acute rupture of the anterior chordae tendinae, without any evidence of infective endocarditis or ischemic heart disease seems to have been attrition of the subvalvular mitral apparatus by the chronic regurgitant jet of aortic incompetence with chronic volume overload. We review the literature with specific focus on the occurrence of this unusual event.

    Full Text Available Coronary malperfusion due to type A aortic dissection is a life-threatening condition where timely recognition and treatment are mandatory. A 77-year-old woman underwent an acute evolving type A aortic dissection mimicking acute myocardial infarction. Two pathophysiologic mechanisms are discussed: either thrombosis migrating from a previously treated giant aneurism of proximal left anterior descending or a local arterial complication due to left main stenting. Recognition of these occurrences in the catheterization laboratory is important to look immediately for surgery.

    We report a case of aortic dissection masquerading as acute ischemic stroke followed by intravenous thrombolysis. A 59-year-old man presented with dizziness. After examination, the patient had a seizure with bilateral Babinski signs. Soon after identifying multiple acute infarctions in both hemispheres on diffusion-weighted brain magnetic resonance (MR) imaging, tissue plasminogen activator (t-PA) was administered. Both common carotid arteries were invisible on MR angiography, and subsequent chest computed tomography revealed an aortic dissection. The emergency operation was delayed for 13 hours due to t-PA administration. The patient died of massive bleeding. PMID:27734002

    Acute aortic dissection (AAD) is a life-threatening disease with an incidence of about 2.6-3.6 cases per 100,000/year. Depending on the site of rupture, AAD is classified as Stanford-A when the ascending aortic thoracic tract and/or the arch are involved, and Stanford-B when the descending thoracic aorta and/or aortic abdominal tract are targeted. It was recently shown that inflammatory pathways underlie aortic rupture in both type A and type B Stanford AAD. An immune infiltrate has been found within the middle and outer tunics of dissected aortic specimens. It has also been observed that the recall and activation of macrophages inside the middle tunic are key events in the early phases of AAD. Macrophages are able to release metalloproteinases (MMPs) and pro-inflammatory cytokines which, in turn, give rise to matrix degradation and neoangiogenesis. An imbalance between the production of MMPs and MMP tissue inhibitors is pivotal in the extracellular matrix degradation underlying aortic wall remodelling in dissections occurring both in inherited conditions and in atherosclerosis. Among MMPs, MMP-12 is considered a specific marker of aortic wall disease, whatever the genetic predisposition may be. The aim of this review is, therefore, to take a close look at the immune-inflammatory mechanisms underlying Stanford-A AAD.

    Full Text Available Native aortic valve thrombosis in primary antiphospholipid syndrome (APLS is a rare entity. We describe a 38-year-old man who presented with neurological symptoms and a cardiac murmur. Transthoracic echocardiography detected a large bicuspid aortic valve thrombus. Laboratory evaluation showed the presence of antiphospholipid antibodies. Anticoagulation was started, and serial echocardiographic studies showed complete resolution of the aortic valve vegetation after 4 months. The patient improved clinically and had no residual symptoms. This report and review of the literature suggests that vegetations in APLS can be treated successfully with conservative treatment, regardless of their size.

    Mutations in FBN1 cause a range of overlapping but distinct conditions including Marfan syndrome (MFS), Weill-Marchesani syndrome (WMS), familial thoracic aortic aneurysms/dissections (FTAAD), acromicric dysplasia (AD), and geleophysic dysplasia (GD). Two forms of acromelic dysplasia, AD and GD, characterized by short stature, brachydactyly, reduced joint mobility, and characteristic facies, result from heterozygous missense mutations occurring in exons 41 and 42 of FBN1; missense mutations in these exons have not been reported to cause MFS or other syndromes. Here we report on probands with MFS and WMS who have heterozygous FBN1 missense mutations in exons 41 and 42, respectively. The proband with WMS has ectopia lentis, short stature, thickened pinnae, tight skin, striae atrophicae, reduced extension of the elbows, contractures of the fingers and toes, and brachydactyly and has a missense mutation in exon 42 of FBN1 (c.5242T>C; p.C1748R). He also experienced a previously unreported complication of WMS, an acute thoracic aortic dissection. The second proband displays classic characteristics of MFS, including ectopia lentis, skeletal features, and aortic root dilatation, and has a missense mutation in exon 41 of FBN1 (c.5084G>A; p.C1695Y). These phenotypes provide evidence that missense mutations in exons 41 and 42 of FBN1 lead to MFS and WMS in addition to AD and GD and also suggest that all individuals with pathogenic FBN1 mutations in these exons should be assessed for thoracic aortic disease and ectopia lentis. Further studies are necessary to elucidate the factors responsible for the different phenotypes associated with missense mutations in these exons of FBN1.

    Introduction: The aim of this retrospective study was to compare the outcome of thoracic endovascular aortic repair (TEVAR) to that of medical therapy in patients with acute type B aortic dissection (TBD). Materials and methods: From July 1996 to April 2008, 88 patients presenting with acute TBD underwent either TEVAR (group A, n = 38) or medical therapy (group B, n = 50). Indications for TEVAR were intractable pain, aortic branch compromise resulting in end-organ ischemia, rapid aortic dilatation and rupture. Follow-up was performed postinterventionally, at 3, 6 and 12 months and yearly thereafter and included clinical examinations and computed tomography (CT), as well as aortic diameter measurements and assessment of thrombosis. Results: Mean follow-up was 33 months in group A and 36 months in group B. The overall mortality rate was 23.7% in group A and 24% in group B, where 4 patients died of late aortic rupture. In group A, complications included 9 endoleaks and 4 retrograde type A dissections, 3 patients were converted to open surgery and 2 needed secondary intervention. None of the patients developed paraplegia. In group B, 4 patients were converted to open surgery and 2 to TEVAR. The maximal aortic diameter increased in both groups. Regarding the extent of thrombosis, our analyses showed slightly better overall results after TEVAR, but they also showed a tendency towards approximation between the two groups during follow-up. Conclusion: TEVAR is a feasible treatment option in acute TBD. However, several serious complications may occur during and after TEVAR and it should therefore be reserved to patients with life-threatening symptoms.

    Acute compartment syndrome is increased tissue pressure exceeding perfusion pressure in a closed compartment resulting in nerve and muscle ischemia. Common precipitating causes are crush injuries, burns, substance abuse, osseous or vascular limb trauma. This is a case of 42year old female with history of hypothyroidism who presented to emergency room with acute onset of severe pain and swelling in right lower extremity. Physical examination was concerning for acute compartment syndrome of right leg which was confirmed by demonstration of elevated compartmental pressures. No precipitating causes were readily identified. Further laboratory testing revealed uncontrolled hypothyroidism. Management included emergent fasciotomy and initiating thyroid hormone replacement. This case represents a rare association between acute compartment syndrome and uncontrolled hypothyroidism. We also discuss the pathogenesis of compartment syndrome in hypothyroid patients and emphasize the importance of evaluating for less common causes, particularly in setting of non-traumatic compartment syndrome.

    Endovascular stent graft treatment of acute thoracic aortic transections is an encouraging minimally invasive alternative to open surgical repair. Between 2006 and 2008, 16 patients with acute thoracic aortic transections underwent evaluation at our institution. Seven patients who were treated with an endovascular stent graft were reviewed. The mean Glasgow Coma Score was 13.0, probability of survival was .89, and median injury severity score was 32. The mean number of intensive care unit days was 7.7, mean number of ventilator support days was 5.4, and hospital length of stay was 10 days. Mean blood loss was 285 mL, and operative time was 143 minutes. Overall mortality was 14%. Procedure complications were a bleeding arteriotomy site and an endoleak. Endovascular treatment of traumatic thoracic aortic transections appears to demonstrate superior results with respect to mortality, blood loss, operative time, paraplegia, and procedure-related complications when compared with open surgical repair literature.

    Background Congenital heart disease (CHD) is a cardinal feature of X chromosome monosomy, or Turner syndrome (TS). Haploinsufficiency for gene(s) located on Xp have been implicated in the short stature characteristic of the syndrome, but the chromosomal region related to the CHD phenotype has not been established. Design We used cardiac MRI to diagnose cardiovascular abnormalities in four non-mosaic karyotype groups based on 50-metaphase analyses: 45,X (n=152); 46,X,del(Xp) (n=15); 46,X,del(Xq) (n=4); and 46,X,i(Xq) (n=14) from peripheral blood cells. Results Bicuspid aortic valves (BAV) were found in 52/152 (34%) 45,X study subjects and aortic coarctation (COA) in 19/152 (12.5%). Isolated anomalous pulmonary veins (APV) were detected in 15/152 (10%) for the 45,X study group, and this defect was not correlated with the presence of BAV or COA. BAVs were present in 28.6% of subjects with Xp deletions and COA in 6.7%. APV were not found in subjects with Xp deletions. The most distal break associated with the BAV/COA trait was at cytologic band Xp11.4 and ChrX:41,500 000. One of 14 subjects (7%) with the 46,X,i(Xq) karyotype had a BAV and no cases of COA or APV were found in this group. No cardiovascular defects were found among four patients with Xq deletions. Conclusions The high prevalence of BAV and COA in subjects missing only the X chromosome short arm indicates that haploinsufficiency for Xp genes contributes to abnormal aortic valve and aortic arch development in TS.

    Cardiovascular surveillance is important in Turner syndrome because of the increased risk of aortic dilation and dissection with consecutively increased mortality. To compare 4-D flow MRI for the characterization of aortic 3-D flow patterns, dimensions and vessel wall parameters in pediatric patients with Turner syndrome and age-matched controls. We performed 4-D flow MRI measuring in vivo 3-D blood flow with coverage of the thoracic aorta in 25 patients with Turner syndrome and in 16 female healthy controls (age mean ± standard deviation were 16 ± 5 years and 17 ± 4 years, respectively). Blood flow was visualized by time-resolved 3-D path lines. Visual grading of aortic flow in terms of helices and vortices was performed by two independent observers. Quantitative analysis included measurement of aortic diameters, quantification of peak systolic wall shear stress, pulsatility index and oscillatory shear index at eight defined sites. Patients with Turner syndrome had significantly larger aortic diameters normalized to BSA, increased vortices in the ascending aorta and elevated helix flow in the ascending and descending aorta compared to controls (all P<0.03). Patients with abnormal helical or vortical flow in the ascending aorta had significantly larger diameters of the ascending aorta (P<0.03). Peak systolic wall shear stress, pulsatility index and oscillatory shear index were significantly lower in Turner patients compared to controls (p=0.02, p=0.002 and p=0.01 respectively). Four-dimensional flow MRI provides new insights into the altered aortic hemodynamics and wall shear stress that could have an impact on the development of aortic dissections. (orig.)

    Marfan syndrome is an inherited disorder characterized by genetic abnormality of microfibrillar connective tissue proteins. Endothelial dysfunction is thought to cause aortic dilation in subjects with a bicuspid aortic valve; however, the role of endothelial dysfunction and endothelial damaging factors has not been elucidated in Marfan syndrome. Flow-mediated dilation, a noninvasive measurement of endothelial function, was evaluated in 39 patients with Marfan syndrome. Aortic diameter was measured at the aortic annulus, aortic root at the sinus of Valsalva, sinotubular junction and ascending aorta by echocardiography, and adjusted for body surface area (BSA). The mean value of flow-mediated dilation was 6.5 ± 2.4 %. Flow-mediated dilation had a negative correlation with the diameter of the ascending thoracic aorta (AscAd)/BSA (R = -0.39, p = 0.020) and multivariate analysis revealed that flow-mediated dilation was an independent factor predicting AscAd/BSA, whereas other segments of the aorta had no association. Furthermore, Brinkman index had a somewhat greater influence on flow-mediated dilation (R = -0.42, p = 0.008). Although subjects who smoked tended to have a larger AscAd compared with non-smokers (AscA/BSA: 17.3 ± 1.8 versus 15.2 ± 3.0 mm/m(2), p = 0.013), there was no significant change in flow-mediated dilation, suggesting that smoking might affect aortic dilation via an independent pathway. Common atherogenic risks, such as impairment of flow-mediated dilation and smoking status, affected aortic dilation in subjects with Marfan syndrome.

  8. How I do it: transapical cannulation for acute type-A aortic dissection

    Directory of Open Access Journals (Sweden)

    Alexiou Christos

    2008-01-01

    Full Text Available Abstract Aortic dissection is the most frequently diagnosed lethal disease of the aorta. Half of all patients with acute type-A aortic dissection die within 48 hours of presentation. There is still debate as to the optimal site of arterial cannulation for establishing cardiopulmonary bypass in patients with type-A aortic dissection. Femoral artery cannulation with retrograde perfusion is the most common method but because of the risk of malperfusion of vital organs and atheroembolism related to it different sites such as the axillary artery, the innominate artery and the aortic arch are used. Cannulation of these sites is not without risks of atheroembolism, neurovascular complications and can be time consuming. Another yet to be popularised option is the transapical aortic cannulation (TAC described in this article. TAC consists of the insertion of the arterial cannula through the apex of the left ventricle and the aortic valve to lie in the sinus of Valsalva. Trans-oesophageal guidance is necessary to ensure correct placement of the cannula. TAC is an excellent method of establishing cardiopulmonary bypass as it is quick, provides a more physiological method of delivering antegrade arterial flow and is the only method to assure perfusion of the true lumen.

    2010-05-01

    Full Text Available Abstract The arterial cannulation site for optimal tissue perfusion and cerebral protection during cardiopulmonary bypass (CPB for surgical treatment of acute type A aortic dissection remains controversial. Right axillary artery cannulation confers significant advantages, because it provides antegrade arterial perfusion during cardiopulmonary bypass, and allows continuous antegrade cerebral perfusion during hypothermic circulatory arrest, thereby minimizing global cerebral ischemia. However, right axillary artery cannulation has been associated with serious complications, including problems with systemic perfusion during cardiopulmonary bypass, problems with postoperative patency of the artery due to stenosis, thrombosis or dissection, and brachial plexus injury. We herein present the case of a 36-year-old Caucasian man with known Marfan syndrome and acute type A aortic dissection, who had direct right axillary artery cannulation for surgery of the ascending aorta. Postoperatively, the patient developed an axillary perigraft seroma. As this complication has, not, to our knowledge, been reported before in cardiothoracic surgery, we describe this unusual complication and discuss conservative and surgical treatment options.

    Full Text Available CONTEXT: Haemolytic uraemic syndrome is a common cause of renal failure in children but it is a rare condition in adults. Acute pancreatitis in adult as a cause of haemolytic uraemic syndrome is very rare. CASE REPORT: A 19-year-old male presented with symptom and signs suggestive of acute pancreatitis which was confirmed as his serum amylase was significantly raised. Within three days of admission he developed acute renal failure with evidence of haemolytic anaemia and thrombocytopenia. A clinical diagnosis of haemolytic uraemic syndrome was made and he was treated with plasma exchange. He made a complete recovery. CONCLUSION: Renal failure in a patient with acute pancreatitis is rarely due to haemolytic uraemic syndrome. But it is important to consider this differential diagnosis so that early treatment can be instituted to prevent mortality.

    Acute dysfunction of mechanical aortic valve prostheses is a life-threatening adverse event. Pannus overgrowth, which is fibroelastic hyperplasia originating from the periannular area, is one cause of dysfunction. The aim of this study was to determine the annual incidence of readmittance resulting from acute obstruction caused by pannus during 30 years of observation in patients with Medtronic-Hall aortic valve prostheses and to analyze the risk factors associated with pannus development. From 1982 to 2004, 1,187 patients in our department underwent aortic valve replacement with Medtronic-Hall mechanical monoleaflet valve prostheses. As of December 31, 2012, 27 of these patients (2.3%) had presented with acute valve dysfunction caused by pannus obstruction. The annual incidence of pannus was 0.7 per 1,000. The median time from the primary operation to prosthetic dysfunction was 11.1 years (range, 1.2 to 26.8 years). Of the 20 patients who underwent reoperation, 2 died. Seven patients died before reoperation. Women had a higher risk for the development of obstructing pannus, and patients with pannus obstruction were younger. Valve size was not an independent risk factor. Women and younger patients are at higher risk for pannus development. When acute dysfunction by pannus is suspected in a mechanical aortic valve, an immediate echocardiogram and an emergency aortic valve replacement should be carried out because of the potential of a fatal outcome.

    2016-11-01

    To describe clinically significant thromboembolism as the result of idiopathic hypereosinophilic syndrome (HES) in a dog. A 3-year-old neutered female Boxer was evaluated for 2-week history of progressive respiratory difficulty and hemoptysis. A brief thoracic ultrasound performed shortly after presentation identified a presumed thrombus within the left atrium. Initial blood work revealed a marked eosinophilia 6.8 × 10(9) /L (6.8 × 10(3) /μL; reference interval, 0.1-2.1 × 10(9) /L [0.1-2.1 × 10(3) /μL]) and evidence of organ dysfunction. Within 24 hours of admission the patient developed acute paraparesis with absent femoral pulses and was euthanized. Necropsy findings included marked infiltration of multiple organs with large numbers of histologically normal eosinophils and numerous thrombi including a large aortic thrombus. This combination of findings resulted in a final diagnosis of HES with associated thromboembolism. Thromboembolism occurs relatively commonly in people with HES. While there are a few case reports of HES in the veterinary literature, this is the first to describe thromboembolism as a manifestation of this disease in a canine patient. © Veterinary Emergency and Critical Care Society 2016.

  1. Life-Threatening Postpneumonectomy Syndrome Complicated with Right Aortic Arch after Left Pneumonectomy

    2015-01-01

    Full Text Available A 54-year-old man with right aortic arch underwent left lower lobectomy and lingular segmentectomy, followed by complete pneumonectomy, for refractory nontuberculous mycobacterial infection. Three months after the pneumonectomy, he developed acute respiratory distress. Computed tomography showed an excessive mediastinal shift with an extremely narrowed bronchus intermedius and right lower bronchus compressed between the right pulmonary artery and the right descending aorta. Soon after the nearly obstructed bronchus intermedius was observed by bronchoscopy, he began to exhibit frequent hypoxic attacks, perhaps due to mucosal edema. Emergent surgical repositioning of the mediastinum and decompression of the bronchus was indicated. After complete adhesiolysis of the left thoracic cavity was performed, to maintain the proper mediastinal position, considering the emergent setting, an open wound thoracostomy was created and piles of gauze were inserted, mildly compressing the heart and the mediastinum to the right side. Thoracoplasty was performed three months later, and he was eventually discharged without any dressings needed. Mediastinal repositioning under thoracostomy should be avoided in elective cases because of its extremely high invasiveness. However, in the case of life-threatening postpneumonectomy syndrome in an emergent setting, mediastinal repositioning under thoracostomy may be an option to save life, which every thoracic surgeon could attempt.

    Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease. Two hours after withdrawal of the drug the symptoms and ST elevation had resolved completely.

    2014-07-01

    Full Text Available Background: Acute aortic dissection can occur at the time of intense physical exertion in strength-trained athletes like weight lifters, bodybuilders, throwers, and wrestlers. Rapid rise in blood pressure and history of hypertension are the most common causes of aortic dissection in athletes. It is a very tragic event because of its high mortality rate of about 32% in young patients. We report a case of aortic dissection in a young weightlifter with a history of anabolic steroid usage with an extensive intimal tear of the aorta at Sino tubular junction and arch. All athletes must be assessed for predisposing factors for aortic dissection, and all patients should be encouraged to undergo appropriate diagnostic studies, like echocardiography and blood pressure monitoring while weightlifting to recognize possible predisposing factors for aortic dissection. Athletes who do have a problem should be encouraged to avoid or limit their exercise or activity by their cardiologist. It is vital that this disastrous event be prevented in young people. In conclusion, although a rare occurrence, AD should be considered in symptomatic patients with any family history of early cardiac deaths, a history suggestive of a connective tissue disorder (that is, multiple joint surgeries or who practice weightlifting.

  4. Acute aortic rupture in a dog with spirocercosis following the administration of medetomidine : clinical communication

    Directory of Open Access Journals (Sweden)

    K.E. Joubert

    2005-06-01

    Full Text Available Spirocercosis is an emerging disease in veterinary medicine. A strong suspicion of spirocercosis is usually evident after a thorough clinical examination and radiography of the chest has been performed. Lesions seen on radiography include an oesophageal mass, spondylitis and oesophageal air. Unfortunately, radiography is not diagnostic and additional diagnostic procedures are required to confirm the diagnosis. Endoscopy is commonly performed to diagnose the condition. The dog presented in this study had radiographic and clinical signs consistent with spirocercosis and definitive diagnosis was required. Shortly after sedation with medetomidine, the dog went into cardiac arrest and failed to respond to resuscitative measures. On post mortem, the diagnosis of spirocercosis was confirmed and the cause of death was identified as acute aortic rupture. Aortic aneurysms are not an uncommon finding and cause of acute death in dogs with spirocercosis. The acute rupture of the aorta in this case is most probably the result of cardiovascular changes associated with the administration of medetomidine. Medetomidine causes an acute rise in systemic vascular resistance with hypertension. The increase in shear stress across the weakened aortic wall resulted in rupture. Caution with the use of medetomidine in patients with spirocercosis is advised.

  5. Cardiorenal Syndrome in Acute Heart Failure Syndromes

    2011-01-01

    Full Text Available Impaired cardiac function leads to activation of the neurohumoral axis, sodium and water retention, congestion and ultimately impaired kidney function. This sequence of events has been termed the Cardiorenal Syndrome. This is different from the increase in cardiovascular complications which occur with primary kidney disease, that is, the so-called Renocardiac Syndrome. The present review discusses the pathogenesis of the Cardiorenal Syndrome followed by the benefits and potential deleterious effects of pharmacological agents that have been used in this setting. The agents discussed are diuretics, aquaretics, natriuretic peptides, vasodilators, inotropes and adenosine α1 receptor antagonists. The potential role of ultrafiltration is also briefly discussed.

    2015-06-01

    The unique characteristics of pulmonary circulation and alveolar-epithelial capillary-endothelial barrier allow for maintenance of the air-filled, fluid-free status of the alveoli essential for facilitating gas exchange, maintaining alveolar stability, and defending the lung against inhaled pathogens. The hallmark of pathophysiology in acute respiratory distress syndrome is the loss of the alveolar capillary permeability barrier and the presence of protein-rich edema fluid in the alveoli. This alteration in permeability and accumulation of fluid in the alveoli accompanies damage to the lung epithelium and vascular endothelium along with dysregulated inflammation and inappropriate activity of leukocytes and platelets. In addition, there is uncontrolled activation of coagulation along with suppression of fibrinolysis and loss of surfactant. These pathophysiological changes result in the clinical manifestations of acute respiratory distress syndrome, which include hypoxemia, radiographic opacities, decreased functional residual capacity, increased physiologic deadspace, and decreased lung compliance. Resolution of acute respiratory distress syndrome involves the migration of cells to the site of injury and re-establishment of the epithelium and endothelium with or without the development of fibrosis. Most of the data related to acute respiratory distress syndrome, however, originate from studies in adults or in mature animals with very few studies performed in children or juvenile animals. The lack of studies in children is particularly problematic because the lungs and immune system are still developing during childhood and consequently the pathophysiology of pediatric acute respiratory distress syndrome may differ in significant ways from that seen in acute respiratory distress syndrome in adults. This article describes what is known of the pathophysiologic processes of pediatric acute respiratory distress syndrome as we know it today while also presenting the much

    Aim: The aim of this study was to investigate a relationship between seasonal variation and incidence of type A acute aortic dissection (AAD) and spontaneous abdominal aneurysm rupture (rAAA) in Canton Tuzla, Bosnia and Herzegovina. Patients and methods: A total of 81 cases, 41 AAD and 40 of ruptured AAA were identified from one center over a 6-year, from 2008 till 2013. In 2012 were admitted (45.6% or 36 patients). Results: Seasonal analysis showed that 19(23.4%) patients were admitted in spring, 15(18.5) in summer, 26(32%) in autumn and 21(25.9) in winter. The most frequent period was autumn/winter with 47 or 58% patients. A causal link between atmospheric pressure (AP) and incidence of rAAA and AAD on seasonal and monthly basis was found.

    Thoracic aortic aneurysms involving the aortic root and/or ascending aorta can lead to acute aortic dissections. Approximately 20% of patients with thoracic aortic aneurysms and dissections (TAAD) have a family history of the disease, referred to as familial TAAD (FTAAD) that can be inherited in an autosomal dominant manner with variable expression with respect to disease presentation, age of onset and associated features. Whole exome sequencing (WES) has been used to identify causative mutations in novel genes for TAAD. The strategy used to reduce the large number of rare variants identified using WES is to sequence distant relatives with TAAD and filter for heterozygous rare variants that are shared between the relatives, predicted to disrupt protein function and segregate with the TAAD phenotype in other family members. Putative genes are validated by identifying additional families with a causative mutation in the genes. This approach has successfully identified novel genes for FTAAD.

    Middle aortic syndrome (MAS) is an extremely rare anomaly and represents both a diagnostic and therapeutic challenge, particularly in young children. A case of a 3.5 year-old child with MAS and arterial hypertension is reported, where owing to the patient's young age and the length of the hypoplastic aortic segment, surgical correction with end-to-end anastomosis was not feasible. Instead of palliative bypass grafting between the thoracic and abdominal aorta, successful percutaneous balloon angioplasty and stenting of the lesion was performed with the assistance of three-dimensional rotational angiography.

    Increased transforming growth factor beta (TGF-β) signaling has been implicated in the pathogenesis of syndromic presentations of aortic aneurysm, including Marfan syndrome (MFS) and Loeys-Dietz syndrome (LDS)1-4. However, the location and character of many of the causal mutations in LDS would intuitively infer diminished TGF-β signaling5. Taken together, these data have engendered controversy regarding the specific role of TGF-β in disease pathogenesis. Shprintzen-Goldberg syndrome (SGS) has considerable phenotypic overlap with MFS and LDS, including aortic aneurysm6-8. We identified causative variation in 10 patients with SGS in the proto-oncogene SKI, a known repressor of TGF-β activity9,10. Cultured patient dermal fibroblasts showed enhanced activation of TGF-β signaling cascades and increased expression of TGF-β responsive genes. Morpholino-induced silencing of SKI paralogs in zebrafish recapitulated abnormalities seen in SGS patients. These data support the conclusion that increased TGF-β signaling is the mechanism underlying SGS and contributes to multiple syndromic presentations of aortic aneurysm. PMID:23023332

    Elevated transforming growth factor (TGF)-β signaling has been implicated in the pathogenesis of syndromic presentations of aortic aneurysm, including Marfan syndrome (MFS) and Loeys-Dietz syndrome (LDS). However, the location and character of many of the causal mutations in LDS intuitively imply diminished TGF-β signaling. Taken together, these data have engendered controversy regarding the specific role of TGF-β in disease pathogenesis. Shprintzen-Goldberg syndrome (SGS) has considerable phenotypic overlap with MFS and LDS, including aortic aneurysm. We identified causative variation in ten individuals with SGS in the proto-oncogene SKI, a known repressor of TGF-β activity. Cultured dermal fibroblasts from affected individuals showed enhanced activation of TGF-β signaling cascades and higher expression of TGF-β-responsive genes relative to control cells. Morpholino-induced silencing of SKI paralogs in zebrafish recapitulated abnormalities seen in humans with SGS. These data support the conclusions that increased TGF-β signaling is the mechanism underlying SGS and that high signaling contributes to multiple syndromic presentations of aortic aneurysm.

    A surgically treated material comprising 18 patinets with heart failure from aortic insufficiency during acute endocarditis has been reviewed. At the time of operation the mean duration of heart failure was 3 weeks and duration of endocarditis 9 weeks. Blood culture was positive in half of the patients, 39% had predisposing valve disease, 14 (78%) had a preoperative heart catheterization. The peroperatively measured regurgitation averaged 55%. All 18 patients had an artifical valve implanted, and the mean observation time for 13 long-term survivors was 3 1/3 years. There were 3 postoperative and 2 late deaths. A long-term survival rate of 73% strongly supports early surgical treatment in patients with aortic insufficiency and heart failure during acute endocarditis.

    Loeys-Dietz syndrome is a recently described autosomal dominant disorder with cardinal manifestations in cardiovascular, craniofacial and skeletal systems. Although the disease has some phenotypic overlap with Marfan syndrome, the disease, that is caused by mutations in the transforming growth factor beta-receptor 1 (TGFBR1) or transforming growth factor beta-receptor 2 (TGFBR2) genes, presents many distinctive features and a particularly aggressive cardiovascular course. We describe prenatal identification of an aortic root aneurysm in a fetus of 19 week of gestation as an early marker of Loeys-Dietz syndrome.

    Eosinophil counts are thought to be associated with atherosclerosis and aortic arch plaques. However, whether these associations exist among patients with acute ischemic stroke remains unclear. We aimed to evaluate the association between absolute eosinophil count (AEC) and aortic arch plaques among these patients. Consecutive acute ischemic stroke patients undergoing transesophageal echocardiography were retrospectively analyzed. Complex aortic arch plaques (CAPs) were defined as plaques ≥4 mm in thickness, with ulcer, or with mobile component. A total of 430 patients (289 male, mean age 69.8±11.4 years) were enrolled. Patients with CAPs (n=169) showed higher mean AEC than those without (167±174/µL versus 127±127/µL; P=0.007). Multivariate analysis showed that increased AEC was independently associated with the presence of CAPs (odds ratio, 2.09; 95% confidence interval, 1.21-3.65). Among patients with acute ischemic stroke, increased AEC was independently associated with the presence of CAPs. Our results suggest that AEC may be a useful predictor for the presence of CAPs in these patients. © 2017 American Heart Association, Inc.

    Acute type A aortic dissection (AcA-AoD) is a surgical emergency associated with very high morbidity and mortality. Unfortunately, the early outcome of emergency surgical repair has not improved substantially over the last 20 years. Many of the same debates occur repeatedly regarding operative extent and optimal conduct of the operation. The question remains: are patients suffering from too large an operation or too small? The pendulum favoring routine aortic valve resuspension, when feasible, has swung towards frequent aortic root replacement. This already aggressive approach is now being challenged with the even more extensive valve-sparing aortic root replacement (V-SARR) in selected patients. Distally, open replacement of most of the transverse arch is best in most patients. The need for late aortic re-intervention has not been shown to be affected by more extensive distal operative procedures, but the contemporary enthusiasm for a distal frozen elephant trunk (FET) only seems to build. It must be remembered that the first and foremost goal of the operation is to have an operative survivor; additional measures to reduce late morbidity are secondary aspirations. With increasing experience, true contraindications to emergency surgical operation have dwindled, but patients with advanced age, multiple comorbidities, and major neurological deficits do not fare well. The endovascular revolution, moreover, has spawned innovative options for modern practice, including ascending stent graft and adaptations of the old flap fenestration technique. Despite the increasingly complex operations and ever expanding therapies, this life-threatening disease remains a stubborn challenge for all cardiovascular surgeons. Development of specialized thoracic aortic teams and regionalization of care for patients with AcA-AoD offers the most promise to improve overall results.

    Pregnancy complicated by aortic dissection in patients with hereditary disorder of connective tissue presents interesting considerations including management of caesarean section with the unexpected need for cardiac surgery in emergency. Generalizations can be made on management principles with long-term follow-up requiring an aggressive individualized approach by a multidisciplinary team. A 33-year-old parturient presenting an aortic dissection at 37 weeks gestation required prompt diagnosis of Ehlers-Danlos syndrome in combination with correct surgical therapy resulted in the survival of both the mother and infant. During the 10-year follow-up, multiple complex dissection required transverse aortic arch and thoracoabdominal aortic replacement.

    Acute aortic dissections are a preventable cause of sudden death if individuals at risk are identified and surgically repaired in a non-emergency setting. Although mutations in single genes can be used to identify at-risk individuals, the majority of dissection case subjects do not have evidence of a single gene disorder, but rather have the other major risk factor for dissections, hypertension. Initial genome-wide association studies (GWASs) identified SNPs at the FBN1 locus associated with both thoracic aortic aneurysms and dissections. Here, we used the Illumina HumanExome array to genotype 753 individuals of European descent presenting specifically with non-familial, sporadic thoracic aortic dissection (STAD) and compared them to the genotypes of 2,259 control subjects from the Atherosclerosis Risk in Communities (ARIC) study matched for age, gender, and, for the majority of cases, hypertension. SNPs in FBN1, LRP1, and ULK4 were identified to be significantly associated with STAD, and these results were replicated in two independent cohorts. Combining the data from all cohorts confirmed an inverse association between LRP1 rs11172113 and STAD (p = 2.74 × 10(-8); OR = 0.82, 95% CI = 0.76-0.89) and a direct association between ULK4 rs2272007 and STAD (p = 1.15 × 10(-9); OR = 1.35, 95% CI = 1.23-1.49). Genomic copy-number variation analysis independently confirmed that ULK4 deletions were significantly associated with development of thoracic aortic disease. These results indicate that genetic variations in LRP1 and ULK4 contribute to risk for presenting with an acute aortic dissection.

    To evaluate the applicability of an off-the-shelf scalloped stent-graft to preserve left subclavian artery (LSA) flow in thoracic endovascular aortic repair (TEVAR) for acute type B aortic dissection. The computed tomography angiograms (CTA) of 70 consecutive patients (median age 64 years; 44 men) with acute Stanford type B aortic dissection were retrospectively analyzed to identify patients in whom a short proximal landing zone (shelf scalloped stent-graft would have been applicable in 23 (41%) patients. In the latter group, the median aortic diameter was 31 mm (range 26-37), the median length of the LSA ostium was 13 mm (range 10-20), and the median width of the LSA ostium was 15 mm (range 11-24). Three differently sized off-the-shelf stent-grafts with the largest scallop possible could have adequately treated 20 (36%) of the 56 patients in the acute phase. In this single-center imaging-based study, involvement of the LSA in the setting of acute type B aortic dissection was seen in 80% of patients treated with TEVAR. Three off-the-shelf stent-grafts would suffice to treat one-third of these acute type B aortic dissections and may offer a relatively simple solution to preserve LSA flow, thereby lowering the risk of malperfusion of the (posterior) cerebrum, spinal cord, and left arm in an urgent/emergent setting.

    Patients with Marfan syndrome (MFS) are at high risk of life-threatening aortic dissections. The condition is caused by mutations in the gene encoding fibrillin-1, an essential component in the formation of elastic fibers. While experimental findings in animal models of the disease have shown the involvement of transforming growth factor-β (TGF-β)- and angiotensin II-dependent pathways, alterations in the vascular extracellular matrix (ECM) may also play a role in the onset and progression of the aortic disease. Lysyl oxidases (LOX) are extracellular enzymes, which initiates the formation of covalent cross-linking of collagens and elastin, thereby contributing to the maturation of the ECM. Here we have explored the role of LOX in the formation of aortic aneurysms in MFS. We show that aortic tissue from MFS patients and MFS mouse model (Fbn1(C1039G/+)) displayed enhanced expression of the members of the LOX family, LOX and LOX-like 1 (LOXL1), and this is associated with the formation of mature collagen fibers. Administration of a LOX inhibitor for 8weeks blocked collagen accumulation and aggravated elastic fiber impairment, and these effects correlated with the induction of a strong and rapidly progressing aortic dilatation, and with premature death in the more severe MFS mouse model, Fbn1(mgR/mgR), without any significant effect on wild type animals. This detrimental effect occurred preferentially in the ascending portion of the aorta, with little or no involvement of the aortic root, and was associated to an overactivation of both canonical and non-canonical TGF-β signaling pathways. The blockade of angiotensin II type I receptor with losartan restored TGF-β signaling activation, normalized elastic fiber impairment and prevented the aortic dilatation induced by LOX inhibition in Fbn1(C1039G/+) mice. Our data indicate that LOX enzymes and LOX-mediated collagen accumulation play a critical protective role in aneurysm formation in MFS.

  4. Central retinal artery occlusion following laser treatment for ocular ischemic aortic arch syndrome

    Full Text Available Objective: Ocular ischemic syndrome is a rare blinding condition generally caused by disease of the carotid artery. We describe a 69-year-old female with a 50 pack-year smoking history with aortic arch syndrome causing bilateral ocular ischemic syndrome. Methods: The patient presented with progressive visual loss and temple pain. Slit lamp biomicroscopy revealed bilateral iris neovascularization. This finding prompted a cardiovascular work up. Panretinal photocoagulation with retrobulbar block was performed in the right eye. Results: A temporal artery biopsy was negative. The carotid duplex sound showed only a 1–39% stenosis. MRA revealed a more proximal occlusion of the aortic branch for which she underwent subclavian carotid bypass surgery. At the one month follow up, the right eye suffered profound vision loss secondary to a central retinal artery occlusion. Conclusion: Ocular neovascularization may be one of the clinical manifestations of aortic arch syndrome. This case also illustrates the limitations of relying solely on carotid duplex ultrasound testing. We caution against overly aggressive panretinal photocoagulation utilizing retrobulbar anesthesia.

    Cosmo Godino

    2012-01-01

    Full Text Available There is a frequent association between aortic valve stenosis and gastrointestinal bleeding, also known as Heyde’s syndrome. In these patients, the aortic valve replacement should be recommended as “gold standard.” In high-surgical-risk patients, the Transcatheter Aortic Valve Implantation (TAVI is an alternative option. However, the risk of bleeding recurrence, related to double antiplatelet therapy started after TAVI, cannot be excluded especially in the first months. We present a case of a patient with a severe aortic valve stenosis and a history of previously documented angiodysplasia and recurrence of gastrointestinal bleeding initially treated only with balloon aortic valvuloplasty that excluded recurrence of bleeding during the subsequent six months of followup. Therefore, a definite transfemoral Edwards XT valve implantation was planned to be performed in case of recurrence of aortic stenosis.

    To describe a new endovascular procedure for acute type A aortic dissection (TAAD) repair. Between 2013 and 2016, 12 patients (average age 54±9.6 years; 10 men) with acute TAAD (mean EURO score 11.4%±3.2%, range 5-17) and unfit for surgery underwent thoracic endovascular aortic repair (TEVAR) with 2 periscope grafts to preserve blood supply to supra-aortic branches plus bypass grafting as needed. If the ascending aorta was dilated to >40 mm, sternotomy was performed to wrap the ascending aorta and reduce its diameter to accommodate the aortic stent-grafts. All patients were successfully treated. Seven patients required bypass grafting, and most of the patients had periscope grafts to the innominate/right common carotid artery and left common carotid artery; only 3 patients had the left subclavian artery preserved. All patients exhibited good hemodynamics and normal pressures after the procedure. The mean procedure time and blood loss were 4.5±1.0 hours and 217±111.5 mL, respectively. Two patients treated emergently died shortly after surgery from multiorgan failure. The average follow-up duration was 17±14.5 months (range 2-42) in the 10 survivors. The remaining patients recovered and none experienced stent-graft thrombosis, stroke, or peripheral artery embolism during follow-up. A procedure that combines sandwich/periscope grafting with TEVAR, wrapping of the aorta, and supra-arch bypass grafting can be used to treat patients with acute TAAD.

    Acute aortic dissection is a life-threatening condition mainly caused by hypertension, atherosclerotic disease and other degenerative diseases of the connective tissue of the aortic wall. Mesothelial/monocytic incidental cardiac excrescences (cardiac MICE) is a rare benign reactive tumor-like lesion composed of admixture of histiocytes, mesothelial cells, and inflammatory cells set within a fibrinous meshwork without a vascular network or supporting stroma. Cardiac MICE occurring in association with aortic dissection is exceptionally rare (only one such case reported to date). We herein report on the surgical repair of two Stanford type A aortic dissections caused by idiopathic giant cell aortitis in a 66-year-old-woman and by atherosclerotic disease in a 58-year-old-man, respectively. In both cases, the dissections could be visualized via computed tomography. Histopathology showed cardiac incidental MICE within the external aortic wall near the pericardial surface which was confirmed by immunohistochemistry. PMID:26097568

    Full Text Available Acute aortic dissection is a life-threatening event in which prompt and correctdiagnosis is associated with better outcomes. In most cases, there is chestor back pain. However, in rare cases, patients have little or no pain andother symptoms are more conspicuous at presentation. The autors reportsthe case of a 47-year-old female patient who sought medical attention forsudden-onset paraplegia. The physical examination was normal except forbilateral lower limb flaccid paralysis, with abolition of deep tendon reflexes andparaesthesia in both feet. Computed tomography showed aortic dissection,with partial thrombosis of the false lumen, starting after the emergence of theleft subclavian artery and extending, toward the bifurcation of the aorta, to theleft iliac artery. After cerebrospinal fluid drainage, the evolution was favorable.

    2017-01-14

    Thoracic aortic diseases, including aneurysms and dissections of the thoracic aorta, are a major cause of morbidity and mortality. Risk factors for thoracic aortic disease include increased hemodynamic forces on the ascending aorta, typically due to poorly controlled hypertension, and heritable genetic variants. The altered genes predisposing to thoracic aortic disease either disrupt smooth muscle cell (SMC) contraction or adherence to an impaired extracellular matrix, or decrease canonical transforming growth factor beta (TGF-β) signaling. Paradoxically, TGF-β hyperactivity has been postulated to be the primary driver for the disease. More recently, it has been proposed that the response of aortic SMCs to the hemodynamic load on a structurally defective aorta is the primary driver of thoracic aortic disease, and that TGF-β overactivity in diseased aortas is a secondary, unproductive response to restore tissue function. The engineering of mouse models of inherited aortopathies has identified potential therapeutic agents to prevent thoracic aortic disease.

    Acute type A aortic dissection (AADA) is a surgical emergency. In patients with aortic arch and descending aorta (DeBakey type I) involvement, performing a total aortic arch replacement with frozen elephant trunk (FET) for supposedly better long-term results is controversial. We hereby present our results. From February 2004 to August 2013, 52 patients with acute aortic dissection DeBakey type I received a FET procedure at our centre (43 males, age 59.21 ± 11.67 years). All patients had an intimal tear in the aortic arch and/or proximal descending aorta. Concomitant procedures were Bentall (n = 15) and aortic valve repair (n = 30). Cardiopulmonary bypass (CPB), X-clamp and cardiac arrest times were 262 ± 64, 159 ± 45 and 55 ± 24 min, respectively. The 30-day mortality rate was 13% (n = 7). Stroke and re-thoracotomy for bleeding were 12% (n = 6) and 23% (n = 12), respectively. Postoperative recurrent nerve palsy and spinal cord injury rates were 10% (5 of 52) and 4% (2 of 52), respectively. Follow-up was 40 ± 24 months. During follow-up, no patient died and no patient required a reoperation for the aortic arch. Our results with FET in AADA show acceptable results. Total aortic arch replacement with an FET in AADA patients does demand high technical skills. In spite of this, we believe FET improves long-term outcomes in cases of AADA with intima tear or re-entry in the aortic arch or the descending aorta (DeBakey type I). Modern grafts with four side branches as well as sewing collars for the distal anastomosis have helped to further 'simplify' the FET implantation. However, such a strategy is not appropriate in all AADA cases; it should be implemented only in experienced centres and only if absolutely necessary. © The Author 2014.

    Aortic dissection (AD) is a potentially life-threatening medical emergency usually encountered in the elderly. Here, we report a 9-year-old child who was incidentally detected to have asymptomatic chronic type B dissecting aneurysm of aorta when he presented with relapse of Hemolytic uremic syndrome (HUS) without any genetic abnormalities like Marfan or Ehler-Danlos syndrome. To the best of our knowledge, this is the first case of AD associated with HUS in a child without any known associated genetic or inherited risk factors.

  17. Neuroleptic-induced acute respiratory distress syndrome

    Directory of Open Access Journals (Sweden)

    Francisco Garcia Soriano

    Full Text Available CONTEXT: A case of neuroleptic malignant syndrome and acute respiratory distress syndrome is presented and discussed with emphasis on the role of muscle relaxation, creatine kinase, and respiratory function tests. CASE REPORT: A 41-year-old man presented right otalgia and peripheral facial paralysis. A computed tomography scan of the skull showed a hyperdense area, 2 cm in diameter, in the pathway of the anterior intercommunicating cerebral artery. Preoperative examination revealed: pH 7.4, PaCO2 40 torr, PaO2 80 torr (room air, Hb 13.8 g/dl, blood urea nitrogen 3.2 mmol/l, and creatinine 90 mmol/l. The chest x-ray was normal. The patient had not eaten during the 12-hour period prior to anesthesia induction. Intravenous halothane, fentanyl 0.5 mg and droperidol 25 mg were used for anesthesia. After the first six hours, the PaO2 was 65 torr (normal PaCO2 with FiO2 50% (PaO2/FiO2 130, and remained at this level until the end of the operation 4 hours later, maintaining PaCO2 at 35 torr. A thrombosed aneurysm was detected and resected, and the ends of the artery were closed with clips. No vasospasm was present. This case illustrates that neuroleptic drugs can cause neuroleptic malignant syndrome associated with acute respiratory distress syndrome. Neuroleptic malignant syndrome is a disease that is difficult to diagnose. Acute respiratory distress syndrome is another manifestation of neuroleptic malignant syndrome that has not been recognized in previous reports: it may be produced by neuroleptic drugs independent of the manifestation of neuroleptic malignant syndrome. Some considerations regarding the cause and effect relationship between acute respiratory distress syndrome and neuroleptic drugs are discussed. Intensive care unit physicians should consider the possibility that patients receiving neuroleptic drugs could develop respiratory failure in the absence of other factors that might explain the syndrome.

    A 64-year-old male with treated Parkinson's disease underwent mechanical valve replacement for aortic valve regurgitation. The antiparkinsonian drugs for internal use were interrupted on the morning of the operative day. After the operation, the patient developed fervescence, muscle rigidity, hidropoiesis and a rise in creatine kinase. The patient was diagnosed as neuroleptic malignant syndrome and given medication dantrolene sodium and antiparkinsonian drugs on the 5th postoperative day. The symptom of neuroleptic malignant syndrome disappeared on 12 postoperative days. As the stress of open heart surgery with extracorporeal circulation trigger off neuroleptic malignant syndrome, the patient with Parkinson's disease need early beginning of antiparkinsonian drugs on account of prevention of neuroleptic malignant syndrome after operation.

    Postpartum headache is a common occurrence with a broad differential diagnosis. Sheehan syndrome, or postpartum pituitary necrosis, is not typically recognized as a cause of postpartum headache. We present a case of Sheehan syndrome that initially presented as severe headache after vaginal delivery complicated by retained placenta and postpartum hemorrhage. The patient was discharged home on postpartum day three but continued to have headaches and returned to hospital on postpartum day six with severe headache, failure to lactate, edema, dizziness, fatigue, nausea and vomiting. Cranial magnetic resonance imaging revealed pituitary infarction consistent with Sheehan syndrome. We discuss the differential diagnosis for postpartum headache, the pathophysiological features of Sheehan syndrome and headache as an atypical acute presentation.

  1. Induction of macrophage chemotaxis by aortic extracts from patients with Marfan syndrome is related to elastin binding protein.

    Directory of Open Access Journals (Sweden)

    Gao Guo

    Full Text Available Marfan syndrome is an autosomal dominantly inherited disorder of connective tissue with prominent skeletal, ocular, and cardiovascular manifestations. Aortic aneurysm and dissection are the major determinants of premature death in untreated patients. In previous work, we showed that extracts of aortic tissues from the mgR mouse model of Marfan syndrome showed increased chemotactic stimulatory activity related to the elastin-binding protein. Aortic samples were collected from 6 patients with Marfan syndrome and 8 with isolated aneurysms of the ascending aorta. Control samples were obtained from 11 organ donors without known vascular or connective tissue diseases. Soluble proteins extracted from the aortic samples of the two patient groups were compared against buffer controls and against the aortic samples from controls with respect to the ability to induce macrophage chemotaxis as measured using a modified Boyden chamber, as well as the reactivity to a monoclonal antibody BA4 against bioactive elastin peptides using ELISA. Samples from Marfan patients displayed a statistically significant increase in chemotactic inductive activity compared to control samples. Additionally, reactivity to BA4 was significantly increased. Similar statistically significant increases were identified for the samples from patients with idiopathic thoracic aortic aneurysm. There was a significant correlation between the chemotactic index and BA4 reactivity, and the increases in chemotactic activity of extracts from Marfan patients could be inhibited by pretreatment with lactose, VGVAPG peptides, or BA4, which indicates the involvement of EBP in mediating the effects. Our results demonstrate that aortic extracts of patients with Marfan syndrome can elicit macrophage chemotaxis, similar to our previous study on aortic extracts of the mgR mouse model of Marfan syndrome (Guo et al., Circulation 2006; 114:1855-62.

    A 58-year old man was admitted to the hospital because of melena. He had a 1-year history of mechanical aortic valve replacement and coronary stent placement because of myocardial infarction and he was taking warfarin and clopidogrel. Esophagogastroduodenoscopy and colonoscopy were negative for bleeding. Capsule endoscopy showed bleeding diffuse angiodysplasia of the small bowel. The patient was treated with octreotide 20 mg, at monthly interval. After 25 months there had been no recurrence of gastrointestinal bleeding. The case suggests that mechanical valve replacement may not prevent gastrointestinal bleeding in Heyde syndrome and that octreotide treatment should be considered in these cases.

    Purpose: To investigate the safety and efficacy of emergency treatment of acute aortic diseases with endovascular stent grafts. Methods: In 11 patients (median age 55 years, range 18 - 85) with acute complications of descending aortic diseases endovascular emergency treatment was performed: traumatic aortic rupture (n = 4), penetrating ulcer with aortobronchial fistula or hematothorax (n = 4), acute type B dissection (n = 2, one with penetration, one with subacute mesenteric ischemia), and symptomatic aneurysm of the thoracic aorta (n = 1) with pain and diameter progression. 15 stent grafts were implanted (Talent n = 11, Vanguard/Stentor n = 4). Stent extension was necessary in 4 cases. In 2 cases graft extension was done during the first procedure (due to distal migration and due to the total length of the aortic aneurysm). In 2 cases graft extension was performed 5 days (due to a new aortic ulcer at the proximal stent struts) and 5 months after the initial procedure (recurrent aortobronchial fistula due to aneurysm progression). 14 of 15 implantations required general anesthesia, one symptomatic thoracic aneurysm was performed in local anesthesia and sedation. Results: 14 of 15 graft procedures were performed using the femoral or iliac approach. One procedure required aortofemoral bypass grafting due to extensive arteriosclerotic stenosis and the stent graft was inserted via the bypass graft. The orifice of the subclavian artery was crossed with bare stent struts in 4 cases without neurological complications. Median follow-up is 27 months (range 6 to 72 months). In traumatic aortic ruptures, immediate sealing of bleeding was achieved and follow-up is inconspicuous at a maximum of 72 months. In cases of aortobronchial fistulas, follow-up is satisfactory (maximum 72 months) despite the necessity for reintervention and graft extension. In one acute type B dissection retrograde dissection of the aortic arch occurred during stent release with stable disease during

    We report a patient with neuroleptic malignant syndrome (NMS) who developed acute renal failure and was successfully treated by hemodialysis. A 60-year-old man with a 26-year history of schizophrenia had been treated with thioridazine and sulpiride. He was admitted to our hospital for muscular rigidity and oliguria. After the diagnosis of NMS with acute renal failure was established, thioridazine and sulpiride were discontinued and hemodialysis was instituted. Renal function gradually improved and hemodialysis was discontinued after 17th treatment. We also reviewed 57 cases of NMS with acute renal failure reported in the literature. To our knowledge, 26 years is the longest latency between initiation of neuroleptic drug treatment and onset of NMS. Our review of reported NMS cases with acute renal failure identified those risks for poor prognosis as high level of BUN, age and female gender.

    2012-01-01

    Full Text Available Peutz-Jeghers syndrome (PJS is an autosomal dominant inherited disorder characterized by mucocutaneous melanin pigmentation and gastrointestinal (GI tract hamartomatous polyps and an increased risk of malignancy. In addition to polyposis, previous studies have reported increased risk of GI and extraGI malignancies in PJS patients, compared with that of the general population. The most common extraintestinal malignancies reported in previous studies are pancreatic, breast, ovarian and testicular cancers.We report the case of a 17-year-old boy who presented with generalized weakness, recurrent sharp abdominal pain and melena, had exploratory laparotomy and ileal resection for ileo-ileal intussusception. Pigmentation of the buccal mucosa was noted. An abdominal computed tomography scan (CT revealed multiple polyps in small bowel loops. Gastroscopy revealed multiple dimunitive polyps in stomach and pedunculated polyp in duodenum. Colonoscopy revealed multiple colonic polyps. Pathological examination of the polyps confirmed hamartomas with smooth muscle arborization, compatible with Peutz-Jeghers polyps. CT scan guided left para-aortic lymph node biopsy revealed the characteristic features of extra-adrenal para-aortic paraganglioma. Although cases of various GI and extra GI malignancies in PJS patients has been reported, the present case appears to be the first in literature in which the PJS syndrome was associated with asymptomatic extraadrenal para-aortic paraganglioma. Patients with PJS should be treated by endoscopic or surgical resection and need whole-body screening.

    An 83-year-old woman presented to the emergency department (ED) via emergency medical services with the chief complaint of "strokelike symptoms." Physical examination revealed altered mental status, tachycardia, hypotension, and a large nonpulsatile periumbilical mass. Bedside ultrasound revealed a 9-cm abdominal aortic aneurysm with absent central flow. Computed tomography scan demonstrated diffuse thoracic and abdominal aortic dilation with rupture into the mediastinum along with left hemothorax. Repeat beside ultrasound demonstrated abdominal aortic aneurysm rupture not seen on the computed tomography scan. Despite aggressive resuscitation, the patient developed bradycardia, which devolved into pulseless electric activity cardiac arrest. She was unable to be resuscitated. The patient's diffuse aneurysmal dilation places her into the small category of patients with a disease entity known as mega aorta syndrome (MAS). Mega aorta syndrome is defined as aneurysmal dilation of the aorta to greater than 6 cm in diameter. Although not in our case, most cases of MAS are symptomatic before catastrophic presentation. The disease progression for these patients is slow and occurs over years. When this disease is recognized early, a surgery known as the elephant trunk procedure can be performed. This operation replaces the entire aorta in multiple stages. This gives the emergency physician a critical role in the diagnosis and outcome of these patients because they may come through the ED for an unrelated complaint early in the disease process. This case report illustrates an advanced case of MAS.

    2013-01-01

    Full Text Available Chilaiditi syndrome is a rare condition occurring in 0.025% to 0.28% of the population. In these patients, the colon is displaced and caught between the liver and the right hemidiaphragm. Patients' symptoms can range from asymptomatic to acute intermittent bowel obstruction. Diagnosis is best achieved with CT imaging. Identification of Chilaiditi syndrome is clinically significant as it can lead to many significant complications such as volvulus, perforation, and bowel obstruction. If the patient is symptomatic, treatment is usually conservative. Surgery is rarely indicated with indications including ischemia and failure of resolution with conservative management.

    In a mouse model of Marfan syndrome, conventional Verhoeff-Van Gieson staining displays severe fragmentation, disorganization and loss of the aortic elastic fiber integrity. However, this method involves chemical fixatives and staining, which may alter the native morphology of elastin and collagen. Thus far, quantitative analysis of fiber damage in aorta and skin in Marfan syndrome has not yet been explored. In this study, we have used an advanced noninvasive and label-free imaging technique, multiphoton microscopy to quantify fiber fragmentation, disorganization, and total volumetric density of aortic and cutaneous elastin and collagen in a mouse model of Marfan syndrome. Aorta and skin samples were harvested from Marfan and control mice aged 3-, 6- and 9-month. Elastin and collagen were identified based on two-photon excitation fluorescence and second-harmonic-generation signals, respectively, without exogenous label. Measurement of fiber length indicated significant fragmentation in Marfan vs. control. Fast Fourier transform algorithm analysis demonstrated markedly lower fiber organization in Marfan mice. Significantly reduced volumetric density of elastin and collagen and thinner skin dermis were observed in Marfan mice. Cutaneous content of elastic fibers and thickness of dermis in 3-month Marfan resembled those in the oldest control mice. Our findings of early signs of fiber degradation and thinning of skin dermis support the potential development of a novel non-invasive approach for early diagnosis of Marfan syndrome.

    Middle aortic syndrome (MAS) follows a course with distal thoracic and abdominal aorta stenosis. It is a rare disease that is usually diagnosed after the first decade of life. Clinical reflection of MAS is often in the form of hypertension and claudication in the lower extremities. Its etiology is unclear, but is known to be associated with congenital or acquired diseases. This pathology, which is accompanied by malignant hypertension, often does not respond to medical treatment. In patients with MAS, surgical treatment is first line recommendation to prevent complications such as hypertension, heart failure, intracranial bleeding, or aortic rupture. In order to draw attention to this disease, presently described is case of high blood pressure detected during routine examination of a child who had no complaint, and discovery of long-segment stenosis in the abdominal aorta identified with echocardiography and conventional angiography.

    Acute compartment syndromes usually occur as a complication of major trauma. While the chronic exertional anterior tibial compartment syndrome is well described in the sports medicine literature, reports of acute tibial compartment syndromes due to physical exertion, or repetitive microtrauma, are rare. The case of an adolescent female who developed an acute anterior compartment syndrome from running in a soccer game is described in this report. Failure to recognize the onset of an acute exertional compartment syndrome may lead to treatment delay and serious complications. Whereas the chronic exertional anterior compartment syndrome is characterized by pain that diminishes with the cessation of exercise, the onset of the acute exertional anterior compartment syndrome is heralded by pain that continues, or increases, after exercise has stopped. Compartment pressure measurement confirms the clinical diagnosis and helps guide treatment. True compartment syndromes require urgent fasciotomy.

    Hypertension in Turner syndrome (TS) is a multifactorial, highly prevalent and significant problem that warrants timely diagnosis and rigorous treatment. The objective of this study was to investigate the association between abnormal aortic arch morphology and hypertension in adult TS patients. This was a single centre retrospective study in 74 adult TS patients (age 29.41 ± 8.91 years) who underwent a routine cardiac MRI. Patients were assigned to the hypertensive group (N = 31) if blood pressure exceeded 140/90 mmHg and/or if they were treated with antihypertensive medication. Aortic arch morphology was evaluated on MRI images and initially assigned as normal (N = 54) or abnormal (N = 20), based on the curve of the transverse arch and the distance between the left common carotid-left subclavian artery. We additionally used a new more objective method to describe aortic arch abnormality in TS by determination of the relative position of the highest point of the transverse arch (AoHP). Logistic regression analysis showed that hypertension is significantly and independently associated with age, BMI and abnormal arch morphology, with a larger effect size for the new AoHP method than for the classical method. TS patients with hypertension and abnormal arch morphology more often had dilatation of the ascending aorta. There is a significant association between abnormal arch morphology and hypertension in TS patients, independent of age and BMI, and not related to other structural heart disease. We suggest that aortic arch morphology should be included in the risk stratification for hypertension in TS and propose a new quantitative method to express aortic arch morphology.

    Gerstmann in 1924. observed in a few patients a concomitant impairment in discriminating their own fingers, writing by hand, distinguishing left from right and performing calculations. He claimed that this tetrad of symptoms constituted a syndromal entity, assigned it to a lesion of the dominant parietal lobe. Since than, Gerstmann`s syndrome (GS) was enigma for neuropsychologists. The aim of this study was to analyze frequency and clinical features of GS among acute stroke patients. We prospectively analyzed 194 acute stroke patients (average age 65±11.06 years, male 113 (58.2%), female 81 (41.8%) hospitalized at department of Neurology, University Clinical Center tuzla, during the six mounths in 2010. For clinical assessment of agraphia, alexia and acalculia we used Minessota test for differential diagnosis of aphasia's. Among these acute stroke patients, 59 (30.40%) had alexia, agraphia and acalculia or different combinations of these disorders. two patients (3.4%) had agraphia and acalculia associated with other part of tetrad of GS: fi nger agnosia and left-right disorientation. they both where men, right handed, and cranial computed tomography scan showed ischemic lesion in the left parietal and left temporoparietal lobe. Gerstmann`s syndrome is rare clinical entity, and has the high value in localization and the lesion is mainly localized to angular gyrus of the dominant hemisphere.

    The neuroleptic malignant syndrome is characterized by hyperpyrexia, muscle rigidity, extrapyramidal motion disorder, vegetative symptoms and mental disorientation. This group of symptoms develops abruptly and may lead to serious complications. One of these complications is the acute renal failure. Permanent muscle rigidity causes the damage of muscle cells which result in myoglobinaemia, myoglobinuria and elevations in muscle related creatine phosphokinase. The authors report the case of a young man who underwent neuroleptic medication because of hebephrenia. During the medication the following symptoms were developed: extrapyramidal symptoms, restlessness, muscle rigidity, high fever. These symptoms eventually lead to acute renal failure caused by rhabdomyolysis (characteristic urine finding, significant elevations in serum creatine phosphokinase). With regards to the neuroleptic malignant syndrome dantrolenum and bromocriptin treatment were applied with the discontinuation of neuroleptic medication. As a part of the complex therapy a massive volumen-supplementing and alkalizing treatment was used but haemodialysis had also become necessary. During the above mentioned treatment symptoms referring to the neuroleptic malignant syndrome resolved and the acute renal failure was cured. The case report calls attention to a specific group of symptoms and the possibilities for prevention and treatment. The above case report is the first observation in Hungary.

    Background Aneurysms affecting the aorta are a common condition associated with high mortality as a result of aortic dissection or rupture. Investigations of the pathogenic mechanisms involved in syndromic types of thoracic aortic aneurysms, such as Marfan and Loeys-Dietz syndromes, have revealed an important contribution of disturbed transforming growth factor (TGF)-β signaling. Objectives This study sought to discover a novel gene causing syndromic aortic aneurysms in order to unravel the underlying pathogenesis. Methods We combined genome-wide linkage analysis, exome sequencing, and candidate gene Sanger sequencing in a total of 470 index cases with thoracic aortic aneurysms. Extensive cardiological examination, including physical examination, electrocardiography, and transthoracic echocardiography was performed. In adults, imaging of the entire aorta using computed tomography or magnetic resonance imaging was done. Results Here, we report on 43 patients from 11 families with syndromic presentations of aortic aneurysms caused by TGFB3 mutations. We demonstrate that TGFB3 mutations are associated with significant cardiovascular involvement, including thoracic/abdominal aortic aneurysm and dissection, and mitral valve disease. Other systemic features overlap clinically with Loeys-Dietz, Shprintzen-Goldberg, and Marfan syndromes, including cleft palate, bifid uvula, skeletal overgrowth, cervical spine instability and clubfoot deformity. In line with previous observations in aortic wall tissues of patients with mutations in effectors of TGF-β signaling (TGFBR1/2, SMAD3, and TGFB2), we confirm a paradoxical up-regulation of both canonical and noncanonical TGF-β signaling in association with up-regulation of the expression of TGF-β ligands. Conclusions Our findings emphasize the broad clinical variability associated with TGFB3 mutations and highlight the importance of early recognition of the disease because of high cardiovascular risk.

    Acute compartment syndrome (ACS) is well known among orthopaedic surgeons. The timely diagnosis and management of ACS is crucial to avoiding its sequelae, including renal failure, ischemic contractures, and limb loss. Despite its relative importance, ACS poses a challenge to many residents and clinicians as diagnosis relies largely on clinical judgment. Timely diagnosis and thorough compartment release are essential to optimizing outcomes in ACS. This video highlights a clinical case in which compartment syndrome of the leg was considered, diagnosed, and surgically managed. This video will present the indications for compartment release and a video-guided demonstration of compartment checks using an arterial line transducer, a 4-compartment fasciotomy with 2 incisions, and temporizing vessel loop closure. Compartment syndrome can be a devastating complication of common fractures. It is essential that orthopaedic practitioners understand the immediacy of intervention. We have a responsibility to provide timely, accurate diagnosis along with expedient surgical management.

    2016-07-19

    BACKGROUND Acute gluteal compartment syndrome is a rare condition that usually results from prolonged immobilization following a traumatic event, conventionally involving the presence of compounding factors such as alcohol or opioid intoxication. If delay in medical treatment is prolonged, severe rhabdomyolysis may ensue, leading to acute renal failure and potentially death. CASE REPORT We report the case of a 23-year-old male with a recent history of incarceration and recreational drug use, who presented with reports of severe right-sided buttock pain and profound right-sided neurological loss following a questionable history involving prolonged immobilization after a fall from a standing position. The patient required an emergent gluteal fasciotomy immediately upon admission and required temporary hemodialysis. After an extended hospital stay, he ultimately recovered with only mild deficits in muscular strength in the right lower extremity. CONCLUSIONS This report demonstrates the importance of early recognition of gluteal compartment syndrome to prevent morbidity and mortality. Compartment syndrome presents in many unique ways, and healthcare practitioners must have a keen diagnostic sense to allow for early surgical intervention. Proper wick catheter measurements should be utilized more frequently, instead of relying on clinical symptomatology such as loss of peripheral pulses for diagnosis of compartment syndrome.

    Background— Aortic dissection remains the most common aortic catastrophe. In the endovascular era, the management of acute type B aortic dissection (ATBAD) is undergoing dramatic changes. The aim of this study is to evaluate the long-term outcomes of patients with ATBAD who were treated at our center over a 13-year period. Methods and Results— We reviewed patients with ATBAD between 2001 and 2014, analyzing variables based on status (complicated [c] versus uncomplicated [u]) and treatment modalities. We defined cATBAD as rupture, expansion of diameter on imaging during the admission, persistent pain, or clinical malperfusion leading to a deficit in cerebral, spinal, visceral, renal, or peripheral vascular territories at presentation or during initial hospitalization. Postoperative outcomes were defined as deficits not present before the intervention. Outcomes were compared between the groups by use of Kaplan-Meier and descriptive statistics. We treated 442 patients with ATBAD. Of those 442, 60.6% had uATBAD and were treated medically, and 39.4% had cATBAD, of whom 39.0% were treated medically to 30.0% with open repair, 21.3% with thoracic endovascular aortic repair, and 9.7% with other open peripheral procedures. Intervention-free survival at 1 and 5 years was 84.8% and 62.7% for uATBAD, 61.8% and 44.0% for cATBAD-medical, 69.2% and 47.2% for cATBAD-open, and 68.0% and 42.5% for cATBAD–thoracic endovascular aortic repair, respectively (P=0.001). Overall survival was significantly related primarily to complicated presentation. Conclusions— In our experience, early and late outcomes of ATBAD were dependent on the presence of complications, with cATBAD faring worse. Although uATBAD was associated with favorable early survival, late complications still occurred, mandating radiographic surveillance and open or endovascular interventions. Prospective trials are required to better determine the optimal therapy for uATBAD. PMID:26304666

    The mechanisms underlying aortic dissection remain to be fully elucidated. We aimed to identify key molecules driving dissection through gene expression profiling achieved by microarray analysis and subsequent in vitro experiments using human aortic endothelial cells (HAECs) and aortic vascular smooth muscle cells (AoSMCs). Total RNA, including microRNA (miRNA), was isolated from the intima-media layer of dissected ascending aorta obtained intraoperatively from acute type A aortic dissection (ATAAD) patients without familial thoracic aortic disease ( n  = 8) and that of non-dissected ascending aorta obtained from transplant donors ( n  = 9). Gene expression profiling was performed with mRNA and miRNA microarrays, and results were confirmed by quantitative polymerase chain reaction (qPCR). Target genes and miRNA were identified by gene ontology analysis and a literature search. To reproduce the in silico results, HAECs and AoSMCs were stimulated in vitro by upstream cytokines, and expression of target genes was assessed by qPCR. Microarray analysis revealed 1536 genes (3.6%, 1536/42 545 probes) and 41 miRNAs (3.0%, 41/1368 probes) that were differentially expressed in the ATAAD group (versus donor group). The top 15 related pathways included regulation of inflammatory response, growth factor activity and extracellular matrix. Gene ontology analysis identified JAK2 (regulation of inflammatory response), PDGFA, TGFB1, VEGFA (growth factor activity) and TIMP3 , TIMP4, SERPINE1 (extracellular matrix) as the target genes and miR-21-5p, a TIMP3 repressor, as target miRNA that interacts with the target genes. Validation qPCR confirmed the altered expression of all 7 target genes and miR-21-5p in dissected aorta specimens (all genes, P  < 0.05). Ingenuity pathway analysis showed TNF-α and TGF-β to be upstream cytokines for the target genes. In vitro experiments showed these cytokines inhibit TIMP3 expression ( P  < 0.05) and enhance VEGFA expression ( P

    Full Text Available We report a case of low cardiac output syndrome caused by dynamic left ventricular (LV outflow obstruction after aortic valve replacement (AVR. This recognized phenomenon probably occurs more frequently than appreciated, and the author suggests that this should be considered when managing patients with severe hemodynamic instability after AVR. In addition, we also focus on the fact that invasive pacemaker systems have significant effects on cardiac output augmentation postoperatively and in long-term management of patients with LV outflow tract (LVOT obstruction following AVR. The possible mechanisms and subsequent treatments are discussed.

    2015-07-01

    Full Text Available Over the last decades, improvement of medical and surgical therapy has increased life expectancy in Marfan patients. Consequently, the number of such patients requiring secondary interventions on the descending thoracic aorta due to new or residual dissections, and distal aneurysm formation has substantially enlarged. Surgical and endovascular procedures represent two valuable options of treatment, both associated with advantages and drawbacks. The aim of the present manuscript was to review endovascular outcomes in Marfan syndrome and to assess the potential role of Thoracic Endovascular Aortic Repair (TEVAR in this subset of patients.

    Objective To determine the distribution of aortic arch and intra/extracranial cerebral arterial atherosclerosis in Chinese patients who had suffered acute ischemic strokes. Methods Eighty-nine patients with acute ischemic strokes were included in this study. Transesophageal echocardiography (TEE) was used to evaluate potential sources of embolisms in the aortic arch and in the heart; duplex ultrasound was used for the carotid artery; and intracranial Doppler (TCD) imaging was used for the middle cerebral artery (MCA), anterior cerebral artery (ACA), posterior cerebral artery (PCA), and basilar artery (BA). An atherosclerotic lesion in the aortic arch was defined as normal (0); mild plaque (1); moderate plaque (2); and protruding plaque or mobile plaque (3). A lesion in the carotid artery was considered a plaque if the maximal carotid plaque thickness was 1.2 mm. TCD results were deemed abnormal if flow velocity was either greater or lower than normal, and, in the case of the MCA, if an asymmetry index above 21% was measured. Results Of the 89 patients, 52 (58.43%) patients showed evidence of aortic arch atherosclerosis (AAA), including 11 (12.36%) patients graded mild, 18 (20.22%) patients graded moderate, and 23 (25.84%) patients graded severe. Of the 23 patients with severe AAA, AAA was determined to be an important potential embolic source in 14 patients. Forty-nine (50.56%) patients had carotid arterial plaques (CAPs). The incidence of carotid plaques was higher among patients with AAA than among patients without AAA (71.15% vs 21.62%, OR=3.291, 95% CI=1.740-6.225, P<0.001). TCD abnormalities affecting the MCA were found in 54 (60.67%) patients. Differences in incidence of TCD abnormalities between patients with AAA and without AAA (69.23% vs 48.65%) were not significant (OR=1.423, 95% CI=0.976-2.076, P=0.05). There was a higher incidence of AAA in older, male patients with a history of diabetes and smoking. Conclusions AAA is an important potential source of

    The major aim of this review was to ascertain whether effective evidence-based treatments for acute coronary syndromes (ACS) are underutilized in women in various geographic areas compared with men. The focus of our review was the relative use of effective treatments in patients with coronary angiographic evidence of obstructive coronary disease, defined as a lumen stenosis >50% of the adjacent non-diseased arterial diameter. We searched MEDLINE, and the Cochrane Database between January 1998 and May 2008. Only a few of the published clinical registries on ACS provide data on treatments dichotomized by confirmed coronary angiographic disease. Consequently, we also accessed individual patient-level data from 3 established ACS registries: the Finnish TACOS (Tampere Acute COronary Syndrome), the British EMMACE 2 (Evaluation of Methods and Management of Acute Coronary Events) and the Argentine PACS-ITALSIA (Prognosis in Acute Coronary Syndromes and the ITALian hospital Sindrome Isquemico Agudo). Despite presenting with higher risk characteristics and having higher in-hospital and 6 months risk of death, women with ACS and obstructive coronary artery disease were apparently treated less aggressively with secondary preventive drugs than were men, being less likely to receive aspirin, beta-blockers and statins at discharge. Overall, coronary revascularization appears to be performed in a similar proportion of women and men - once angiography has been performed and the coronary anatomy is known. However, substantial geographic variation exists in the relative rate of coronary angiography in men and women. In United Kingdom coronary revascularization tends to be done less frequently in women. Our study, therefore, demonstrates a gender bias in the delivery of secondary drug treatments for ACS, even for patients with documented significant coronary disease.

    Extended arch repair for acute type A aortic dissection remains controversial. Our strategy for acute type A aortic dissection was primary entry resection and tear-oriented ascending/hemiarch replacement for patients with the intimal tear in the ascending aorta or is not found in the ascending/aortic arch. Extended total/partial arch replacement was performed for patients with the tear located in the aortic arch. Here, we investigated the validity of our strategy from the viewpoints of long-term survival and reoperation. Between 2003 and 2014, 267 acute type A aortic dissection patients (mean age; 65.2 ± 12.9 years, 134 men and 133 women) underwent emergent surgical repair. Ascending/hemiarch replacements were performed in 225 patients (ascending/hemiarch group) and total/partial arch replacements in 42 patients (arch group). Early and late outcomes of both groups were compared. The hospital mortality rates in the ascending/hemiarch and the arch groups were 4.4 and 9.5 %, respectively (p = 0.25). For ascending/hemiarch and arch groups, the actuarial survival rates were 80.7 vs. 84.3 % after 5 years, and 66.4 vs. 74.6 %, respectively, after 10 years (p = 0.94). For ascending/hemiarch and arch groups, reoperation-free survival rates were 72.1 vs. 77.1 % after 5 years, and 62.0 vs. 67.1 %, respectively, after 10 years (p = 0.85). We observed no significant differences in the actuarial survival or reoperation-free survival rates between the groups. These findings suggest that tear-oriented ascending/hemiarch replacement for acute type A aortic dissection does not increase the risk of long-term mortality or reoperation.

    Full Text Available Ovarian hyperstimulation syndrome is a serious and potentially life-threatening physiological complication that may be encountered in patients who undergo controlled ovarian hyperstimulation cycles. The syndrome is typically associated with regimes of exogenous gonadotropins, but it can be seen, albeit rarely, when clomiphene is administered during the induction phase. Although this syndrome is widely described in scientific literature and is well known by obstetricians, the knowledge of this pathological and potentially life-threatening condition is generally less than satisfactory among physicians. The dramatic increase in therapeutic strategies to treat infertility has pushed this condition into the realm of acute care therapy. The potential complications of this syndrome, including pulmonary involvement, should be considered and identified so as to allow a more appropriate diagnosis and management. We describe a case of a woman with an extremely severe (Stage 6 ovarian hyperstimulation syndrome who presented ascites, bilateral pleural effusion and severe respiratory failure treated with non-invasive ventilation. The patient was admitted to the intensive care unit because of severe respiratory failure, ascites, and bilateral pleural effusion due to ovarian hyperstimulation syndrome. Treatment included non-invasive ventilation and three thoracentesis procedures, plus the administration of albumin, colloid solutions and high-dose furosemid. Severe form of ovarian hyperstimulation syndrome is observed in 0.5-5% of the women treated, and intensive care may be required for management of thromboembolic complications, renal failure and severe respiratory failure. Pulmonary intensive care may involve thoracentesis, oxygen supplementation and, in more severe cases, assisted ventilation. To our knowledge, there have been only two studies in English language medical literature that describe severe respiratory failure treated with non

    Colonic ischemia is a recognized complication of either open or endovascular abdominal aortic aneurysm repair. The clinical difficulty in establishing the diagnosis, the severity of this complication and the patient's poor physiological status may lead to a fatal outcome. We presented a case of ischemic colitis in a patient with patent hypogastric arteries that occurred after an endovascular abdominal aortic aneurysm repair as well as a review of the available literature. The patient's preoperative, intraoperative and postoperative data were recorded. A thorough search through the Google data and Medline to review similar cases or any analyses that referred to ischemic colitis after endovascular abdominal aneurysm repair was conducted. A 76-year-old male was admitted to our department for an elective endovascular repair of an 8 cm in diameter abdominal aortic aneurysm. A Zenith bifurcation graft was implanted. The whole procedure was uneventful and the final angiogram showed an accurate deployment of the endograft without endoleaks and patency of both hypogastric arteries. During the 1st postoperative day, the patient developed symptoms of acute abdomen in combination with metabolic acidosis and oliguria. He underwent an exploratory laparotomy, which revealed necrosis of the sig-moid. A Hartmann's procedure was performed;the patient was transferred to the intensive care unit where he deceased after 24 h. Postoperative ischemic colitis has been described after open abdominal aneurysm repair. The description of this complication has been reported since the early phase of endovascular abdominal aneurysm repair development with a current incidence of 1.5%–3.0%. Possible mechanisms that may contribute to ischemic colitis in spite of the presence of patent hypogastric arteries include athe-roembolization, shock, vasopressive drugs and inferior mesenteric artery occlusion.

  16. Pulmonary and extrapulmonary acute respiratory distress syndrome: myth or reality?

    2008-02-01

    The pathogenesis of acute respiratory distress syndrome has been explained by the presence of a direct (pulmonary) or indirect (extrapulmonary) insult to the lung parenchyma. Evidence indicates that the pathophysiology of acute respiratory distress syndrome may differ according to the type of the insult. This article presents a brief overview of the differences between pulmonary and extrapulmonary acute respiratory distress syndrome, and discusses the interactions between lung functional, morphological aspects, and response to different therapies, both in experimental models and in patients with acute respiratory distress syndrome. Many researchers recognize that experimental pulmonary and extrapulmonary acute respiratory distress syndrome are not identical when considering morpho-functional aspects, the response to positive end-expiratory pressure and recruitment manoeuvre, prone position and other adjunctive therapies. Contradictory results have been reported in different clinical studies, however, which may be attributed to the difficulty of classifying acute respiratory distress syndrome in one or the other category, and being confident of the onset, the phase and the severity of acute respiratory distress syndrome in all patients. Heterogeneous acute respiratory distress syndrome patients are still considered to suffer from one syndrome, and are treated in the same way. Understanding the range of different pathways that lead to pulmonary dysfunction makes it possible to better target clinical treatment.

    Full Text Available Acute respiratory distress syndrome (ARDS is a clinical syndrome of severe dyspnea of rapid onset, hypoxemia, and diffuse pulmonary infiltrates leading to respiratory failure. ARDS occurs in pregnancy and may have unique causes. Overall mortality for both the mother and the fetus is high and significant morbidity can persist even after initial recovery. ARDS is associated with obstetric causes such as amniotic fluid embolism, preeclampsia, septic abortion, and retained products of conception or non - obstetr ic causes that include sepsis, aspiration pneumonitis, influenza pneumonia, blood transfusions, and trauma. Here is a 24 years old female admitted with 7months of amenorrhea, who presented with respiratory failure, she was intubated and ventilated for 47da ys. She recovered, and a live baby was delivered. She was discharged after 73days.

    Acute respiratory distress syndrome (ARDS) is a condition with a high morbidity and mortality rate, and treatment is often long and costly. Prone positioning is a rarely used intervention for patients with this syndrome, although research suggests it may be effective. A literature search was undertaken to examine the effects of prone positioning on oxygenation, morbidity and mortality in patients with ARDS. It revealed that prone positioning, when used with low tidal volume ventilation over an extended period, may reduce mortality rates in selected patients with severe ARDS. The selection of patients with severe ARDS for prone positioning should be done on a case-by-case basis to maximise benefits and minimise complications. Further research is required on the use of prone positioning in patients with severe ARDS to support or disclaim the therapy's use in practice, and to compare confounding variables such as ideal prone duration and mechanical versus manual pronation.

    2016-01-01

    Stiff person syndrome (SPS) is a rare neuroimmunological disorder characterized by severe progressive muscle stiffness in axial and lower extremity musculature with superimposed painful muscle spasms. Although chest pain is a common reason for SPS patients presenting to the emergency room, this disorder is overlooked and not part of the differential diagnosis of chest pain. Herein, we report on a middle age male presenting with classic symptoms of SPS; however, due to the rarity of this disease, he was initially thought to have acute coronary syndrome. Clinicians should consider the diagnosis of SPS in patients with fluctuating muscle spasms in the torso and/or extremities in the setting of repeated hospitalizations without subsequent symptom relief.

    Acute carpal tunnel syndrome (ACTS) is rare and is mostly the result of fractures of the distal radius or the carpal bones. This paper gives the first report of an ACTS following contusion of the wrist as the result of an extensive haematoma of the flexor tendon sheath, which did not appear until 50 hours after the injury was sustained but then developed rapidly. The patient suffers from Marfan syndrome. This disease is associated with pathologic changes to the major vessels, and especially the aorta, and of the smaller peripheral vessels. It is assumed that the haematoma arose from an aneurysm of such a small vessel. The treatment of choice in ACTS is emergency incision of the carpal tunnel.

    @@atients with Acute Coronary Syndrome (ACS)are a clinical continuum-with patients presenting with unstable angina on one end, with patients with ST elevation myocardial infarction (STEMI) at the other end of the spectrum. In between are those with non- ST elevation myocardial infarction (NSTEMI) The pathophysiology is similar in these patients, namely isruption and fissuring of an atheromatous plaque,leading to enhanced platelet activation and local vasohyperactivity, with reduced flow and thrombus formation. While medical experts have reached consensus in the management of STEMI patients (thrombolysis nd / or percutaneous coronary intervention), optimalmanagement of patients with UA/NSTEMI remainsunclear.

    A 44-year-old woman complained of abdominal pain of 4 days' duration accompanied by vomiting and painful urination. The admitting physician noted neurologic signs consistent with axonal polyneuropathy and hyponatremia. In the absence of other explanations for the syndrome, SIADH was diagnosed. Because of the nonspecific nature of the observations, the patient was assessed by various specialists and admitted to the anesthetic recovery unit due to worsening of neurologic signs and suspicion of acute intermittent porphyria. The diagnosis was confirmed by laboratory findings of elevated d-aminolevulinic acid and porphobilinogen levels and normal stool porphyrins. The patient improved with intravenous hematin infused over 4 days.

    Acute coronary syndrome (ACS) is caused by a critical obstruction of a coronary artery because of atherosclerotic coronary artery disease. Three specific conditions are included: ST elevation myocardial infarction, non-ST elevation myocardial infarction, and unstable angina. The ST segment on the electrocardiogram is a sensitive and specific marker of myocardial ischemia and infarction; however, ST segment deviation is regional not global, thus the ECG lead must be placed over the affected region of the myocardium. This article describes ACS and infarction and the use of ST segment monitoring to detect these conditions.

    The diagnosis and treatment of the acute compartment syndrome is of paramount importance. Unless the viscious cycle is intervened at an appropriately early time it will result in irreversible damage leading to disability. In this review article we are discussing the basic pathophysiological process through which the various aetiological factors causing increased compartmental pressure lead to the progressive death of muscles and nerves. We also discuss the various clinical features that aid in the diagnosis and the role of intracompartmental pressure measurements. Finally we hope to ascertain the basic principles and the surgical techniques for treating this condition effectively. PMID:22022031

    Objective To explore the differences in the characteristics of acute aortic dissection (AAD) among less and more economically developed countries with various cultures and races Data sources Reports from the International Registry of Acute Aortic Dissection (IRAD) and the mainland of China (MC) were collected by searching the PubMed Database and the Chinese Journal Full-text Database from January 2000 to March 2009.Study selection Those reports from IRAD and MC containing larger numbers of cases and complete patients' information were selected, which focused on concrete issues of diagnosing or managing AAD were excluded if they were not able to reflect the overall characteristics of this condition. And the data from the article containing the largest number patients reported by the same medical center in MC were taken into statistics.Results AAD patients from MC were significantly younger than IRAD countries and the percentage of male patients in the Chinese group was higher than IRAD countries (80.7% vs. 68.6%, P <0.001). Patients in MC were less likely to present with typical symptoms and signs except for any focal neurological deficits. Different from the IRAD group,Chinese patients were prone to undergo magnetic resonance imaging (MRI) to make the diagnosis of AAD (45.5% vs.11.6%, P <0.001). The in-hospital mortality was similar between 2 groups but only smaller proportion of AAD patients in MC underwent surgical or medicaltreatment.Conclusions The general characteristics of AAD patients in MC were shown and differences in some clinical variables between MC and IRAD groups still existed.

  6. Type B Aortic Dissection: Management Updates

    Full Text Available Acute aortic dissection (AAD is the most frequent catastrophic event of the aorta; it occurs nearly three times as frequently as the rupture of abdominal aortic aneurysm. Sixty percent of dissection cases are classified as proximal or type A and 40% as distal or type B, according to the Stanford Classification. The most frequent causes of death in acute type B dissection are aortic rupture and malperfusion syndrome.We herein review recent data suggesting different management modalities of type B aortic dissection, including medical, surgical, and endovascular treatments. Although medical therapy is still the standard approach in uncomplicated cases, there are subgroups of patients who may benefit from endovascular management. Endovascular techniques or surgery are valuable options for complicated cases. Hybrid suites, multidisciplinary approaches, and good imaging techniques can be considered as the key to success in this regard.

    2004-01-01

    Objective To summarize current understanding of the roles of anti-inflammatory and proinflammatory mechanisms in the development of atherosclerosis and acute coronary syndrome and to postulate the novel concept of inflammation stress as the most important factor triggering acute coronary syndrome. Moreover, markers of inflammation stress and ways to block involved pathways are elucidated.Data sources A literature search (MEDLINE 1997 to 2002) was performed using the key words "inflammation and cardiovascular disease". Relevant book chapters were also reviewed.Study selection Well-controlled, prospective landmark studies and review articles on inflammation and acute coronary syndrome were selected.Data extraction Data and conclusions from the selected articles providing solid evidence to elucidate the mechanisms of inflammation and acute coronary syndrome were extracted and interpreted in the light of our own clinical and basic research.Data synthesis Inflammation is closely linked to atherosclerosis and acute coronary syndrome. Chronic and long-lasting inflammation stress, present both systemically or in the vascular walls, can trigger acute coronary syndrome.Conclusions Inflammation stress plays an important role in the process of acute coronary syndrome. Drugs which can modulate the balance of pro- and anti-inflammatory processes and attenuate inflammation stress, such as angiotensin-converting enzyme (ACE) inhibitors/angiotensin Ⅱ receptor blockers, statins, and cytokine antagonists may play active roles in the prevention and treatment of acute coronary syndrome when used in addition to conventional therapies (glycoprotein Ⅱb/Ⅲa receptor antagonists, mechanical intervention strategies, etc).

    Bicuspid aortic valve (BAV) is a congenital anomaly associated with structural weakness of the aortic wall. Sudden onset of symptoms in patients with BAV, such as sudden severe back pain, and pulse inequality between the extremities or tension disparity should alert clinicians to acute aortic syndromes, as they require prompt diagnosis and management. Retrograde aortic dissection, which is a rare form of acute aortic syndrome, is an uncommon life-threatening entity and may produce atypical computed tomography (CT) or magnetic resonance imaging findings, leading to difficulty in diagnosis. We report on a 51-year-old male patient with BAV and spontaneous retrograde ascending aortic dissection. CT findings were confusing and the diagnosis was made via transoesophageal echocardiography. After the diagnosis, the patient was treated with a modified Bentall procedure. He did not have any complications and was stable four months after the operation.

    Objectives This study sought to characterize the inflammatory infiltrate in ascending thoracic aortic aneurysm (TAAs) in patients with Marfan syndrome (MFS), familial TAA (FTAA), and non-familial TAA cases. Background TAAs are associated with a pathologic lesion termed medial degeneration, which was described as a noninflammtory lesion. TAAs are a complication of MFS and also can be inherited in an autosomal dominant manner of FTAA. Methods Full aortic segments were collected from patients undergoing elective repair with MFS (n=5), FTAA (n=6) and TAAs (n=9), along with control aortas (n=5). Immunohistochemistry staining was performed using antibodies directed against markers of lymphocytes and macrophages. Real-time PCR analysis was performed to quantify the expression level of T cell receptor β chain variable region gene. Results Immunohistochemisty of TAA aortas demonstrated that the media and adventitia from MFS, FTAA and sporadic cases had increased numbers of T lymphocytes and macrophages when compared with control aortas. The number of T cells and macrophages in the aortic media of the aneurysm correlated inversely with the patient’s age at the time of prophylactic surgical repair of the aorta. Surprisingly, T cell receptor profiling indicated a similar clonal nature of the T cells in the aortic wall in a majority of aneurysms, whether the patient had MFS, FTAA or sporadic disease. Conclusion These results indicate that infiltration of inflammatory cells contributes to the pathogenesis of TAAs. Superantigen-driven stimulation of T lymphocytes in the aortic tissues of the TAA patients may contribute to the initial immune response. Ultramini-Abstract This study sought to investigate the infiltration of T-lymphocytes and macrophage in the aortas of patients with MFS, FTAA and sporadic TAAs. The results indicate that infiltration of inflammatory cells contributes to the pathogenesis of TAAs and superantigen-driven stimulation of T-lymphocytes may contribute to

    Diabetes mellitus is an independent risk factor for cardiovascular disease. To compare the efficacy of devices for continuous glucose monitoring and capillary glucose monitoring in hospitalized patients with acute coronary syndrome using the following parameters: time to achieve normoglycemia, period of time in normoglycemia, and episodes of hypoglycemia. We performed a pilot, non-randomized, unblinded clinical trial that included 16 patients with acute coronary artery syndrome, a capillary or venous blood glucose ≥ 140 mg/dl, and treatment with a continuous infusion of fast acting human insulin. These patients were randomized into 2 groups: a conventional group, in which capillary measurement and recording as well as insulin adjustment were made every 4h, and an intervention group, in which measurement and recording as well as insulin adjustment were made every hour with a subcutaneous continuous monitoring system. Student's t-test was applied for mean differences and the X(2) test for qualitative variables. We observed a statistically significant difference in the mean time for achieving normoglycemia, favoring the conventional group with a P = 0.02. Continuous monitoring systems are as useful as capillary monitoring for achieving normoglycemia. Copyright © 2012 Instituto Nacional de Cardiología Ignacio Chávez.

    Psychopathologic and nosologic issues of acute paranoid and Kandinsky-Clerambault syndromes are discussed on the background of clinical studies of 225 schizophrenic patients with these syndromes being initial manifestations. The data on the syndromes typology, clinical value and prognosis of acute delirious disorders are presented. These are shown to be not confined to progredient schizophrenia, including its paranoid form. Rather, they can manifest a course of the disease unspecific for schizophrenia, the so-called schizophrenic reactions and phasic states thus reflecting the course of latent schizophrenia. A differentiated approach to clinical and psychopathological analysis of acute delirious syndromes in schizophrenia is essential for adequate choice of medicosocial measures and epidemiologic investigations.

    Sheehan's syndrome occurs as a result of ischemic pituitary necrosis secondary to severe postpartum bleeding. It is one of the most common causes of hypopituitarism, characterized by variable clinical presentation. Acute kidney injury occurs rarely in Sheehan's syndrome and most of the cases have been found to be precipitated by rhabdomyolysis. We here present a case of Sheehan's syndrome with acute kidney injury where theprecipitating cause was chronic hypocortisolemia. We believe this is the first reported case of Sheehan's syndrome in which acute kidney injury was precipitated by adrenal insufficiency.

    Acute esophageal necrosis, which presents as a black esophagus on endoscopy, is a rare disorder that is poorly described in the medical literature. In this study, we analyze all cases reported to date to define risk factors, clinical presentation, endoscopic features, histologic appearance, treatment, complications, outcome and etiopathogenesis of the disease and to describe a distinct medical syndrome and propose a staging system. We searched Medline and PubMed from January 1965 to February 2006 for English-language articles using the key words "acute esophageal necrosis," "necrotizing esophagitis," and "black esophagus." A total of 88 patients were reported in the literature during the 40 years, 70 men and 16 women with an average age of 67 years. Patients were generally admitted for gastrointestinal bleeding and cardiovascular event/shock. Patients presented with hematemesis and melena in more than 70% of the cases. Upper endoscopy showed black, diffusely necrotic esophageal mucosa predominantly affecting the distal third of the organ. Necrosis was confirmed histologically in most cases. Complications included strictures or stenoses, mediastinitis/abscesses, and perforations. Overall mortality was 31.8%. This study provides a structured approach to identifying risk factors, diagnosis, and pathogenesis of the acute esophageal necrosis. Risk factors include age, male sex, cardiovascular disease, hemodynamic compromise, gastric outlet obstruction, alcohol ingestion, malnutrition, diabetes, renal insufficiency, hypoxemia, hypercoagulable state, and trauma. Mechanism of damage is usually multifactorial secondary to ischemic compromise, acute gastric outlet obstruction, and malnutrition. Overall, acute esophageal necrosis should be viewed as a poor prognostic factor, associated with high mortality from the underlying clinical disease.

    An 80-year-old woman with Parkinson's disease was scheduled for open heart surgery to repair thoracic aortic aneurysm. Parkinson's symptoms were normally treated using oral levodopa (200 mg), selegiline-hydrochloride (5 mg), bromocriptine-mesilate (2 mg), and amantadine-hydrochloride (200 mg) daily. On the day before surgery, levodopa 50mg was infused intravenously. Another 25 mg of levodopa was infused immediately after surgery. Twenty hours later, the patient developed tremors, heyperventilation, but no obvious muscle rigidity. Two days after surgery, the patient exhibited high fever, hydropoiesis, elevated creatine kinase, and a rise in blood leukocytes. She was diagnosed with neuroleptic malignant syndrome. She was intubated, and received dantrolene sodium. Symptoms of neuroleptic malignant syndrome disappeared on the fourth postoperative day. The stress of open heart surgery, specifically extracorporeal circulation and concomitant dilution of levodopa, triggered neuroleptic malignant syndrome in this patient. Parkinson's patients require higher doses of levodopa prior to surgery to compensate and prevent neuroleptic malignant syndrome after surgery.

    To evaluate predictors of early and long-term outcomes of surgical repair of acute Type A aortic dissection. Retrospective single-centre study evaluating patients surgically treated between 1998 and 2013. Clinical follow-up was performed. Complications were classified according to the International Aortic Arch Surgery Study Group recommendations. Statistical analysis included univariate and multivariate analysis of preoperative and operative data. One hundred eighty-five patients were evaluated. The follow-up was complete for 180 patients (97 %). Mean age was 63 years, 82 % had a DeBakey type I aortic dissection, 18 % a type II. Eleven patients (6 %) died intraoperatively, 119 of the remaining (68 %) had postoperative complications. Thirty-day mortality was 21 % (38 patients). Average ICU and hospital stay were 6 and 14 days, respectively. During a mean follow-up time of 6 ± 4 years we observed 44 deaths (31 %). Twenty patients (14 %) needed late thoracic aorta reoperation. Results from the multivariate analysis are as follows. Thirty-day mortality was associated with abdominal pain at presentation (p < 0.01). The incidence of postoperative complications was related to older age at intervention (p < 0.01) and longer cross-clamp time (p < 0.01). Mortality at follow-up was significantly increased by older age at intervention (p < 0.01), with a logarithmic growth after 60 years, female sex (p < 0.01), preoperative limb ischemia (p = 0.02) and DHCA (p < 0.01). The surgical results of type A aortic dissection are affected by age at intervention with a logarithmic increase of late mortality in patients older than 60 years.

    Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder affecting 1 in 3,000 people. Cardiovascular involvement is a prominent feature of MFS, with aortic dissection and/or rupture being the leading cause of death. Advances in the medical and surgical care of patients with MFS have improved survival. Hospital resource utilization and outcomes have not been evaluated in a large population of patients with MFS. We sought to analyze pediatric hospital resource utilization and outcomes in patients with MFS. Nationally distributed data from 43 pediatric hospitals in the 2004-2011 Pediatric Health Information System database were used to identify patients admitted to the hospital with International Classification of Diseases-9th Revision codes for a diagnosis of MFS. Aortic aneurysm (AA) with or without dissection, length of stay (LOS), and hospital charges were determined. During the study period, there were 1,978 admissions in 1,228 patients with MFS. AA was present in 217 (11%) admissions in 188 (15%) patients (63% male). Mean age of patients with AA was 13.8 ± 5.9 years. Aortic dissection or rupture was present in 15 (7% with AA) admissions in 15 (8% with AA) patients (mean age 15.7 ± 5.2 years). Other cardiac diagnoses occurred more commonly in the AA cohort (p < 0.0001), regardless of the reason for admission. Cardiothoracic surgical procedures were performed in 116 AA admissions (53%). Mean LOS, hospital charges per admission, and charges per day were significantly higher in AA cohort compared to those without AA. In-hospital mortality for AA was 2%. The presence of AA in patients with MFS increases hospital resource utilization. Cardiothoracic surgeries are commonly performed in this cohort. Other cardiovascular diagnoses are more prevalent in patients with AA suggesting a more severe phenotype.

    The acute radiation syndrome (ARS) occurs after whole-body or significant partial-body irradiation (typically at a dose of >1 Gy). ARS can involve the hematopoietic, cutaneous, gastrointestinal and the neurovascular organ systems either individually or in combination. There is a correlation between the severity of clinical signs and symptoms of ARS and radiation dose. Radiation induced multi-organ failure (MOF) describes the progressive dysfunction of two or more organ systems over time. Radiation combined injury (RCI) is defined as radiation injury combined with blunt or penetrating trauma, burns, blast, or infection. The classic syndromes are: hematopoietic (doses >2-3 Gy), gastrointestinal (doses 5-12 Gy) and cerebrovascular syndrome (doses 10-20 Gy). There is no possibility to survive after doses >10-12 Gy. The Phases of ARS are-prodromal: 0-2 days from exposure, latent: 2-20 days, and manifest illness: 21-60 days from exposure. Granulocyte-colony stimulating factor (G-CSF) at a dose of 5 μg/kg body weight per day subcutaneously has been recommended as treatment of neutropenia, and antibiotics, antiviral and antifungal agents for prevention or treatment of infections. If taken within the first hours of contamination, stable iodine in the form of nonradioactive potassium iodide (KI) saturates iodine binding sites within the thyroid and inhibits incorporation of radioiodines into the gland. Finally, if severe aplasia persists under cytokines for more than 14 days, the possibility of a hematopoietic stem cell (HSC) transplantation should be evaluated. This review will focus on the clinical aspects of the ARS, using the European triage system (METREPOL) to evaluate the severity of radiation injury, and scoring groups of patients for the general and specific management of the syndrome.

    2004-09-01

    We report the anesthesic and obstetrical management of two pregnant patients with Marfan's syndrome. An important dilatation of the root of aorta was established at the beginning of the pregnancy. Based on a review of the literature and our experience, we searched for clues to identify the ideal term and the best mode of delivery, and which type of anesthesia may be the more appropriate in patients with aortic dilatation. No consensus can be found in the literature as far as anesthesia and obstetric management of these patients is concerned. Pregnancy must be continued as long as possible to ensure adequate fetal growth but fetal extraction should not be delayed if the diameter of the aorta enlarges too much. A diameter of 40 mm is probably the higher limit to accept for vaginal delivery. Beyond, cautious cesarean section would be advisable. In the absence of dural ectasia or a technical problem, neuraxial anesthesia is a good option. According to the severity of the aortic dilatation and its evolution, specific management, based on good cooperation between obstetricians and anesthesiologists, is the key of a successful and safe childbirth.

    Thoracic aortic diseases (TAD) are relatively frequent conditions associated with high mortality. Recently, several reports have demonstrated the safety and efficacy of endovascular stent-graft (EVG) placement for TAD as an alternative to open surgery. We report our experience in management of thoracic aortic syndrome on 56 consecutive patients with TAD that underwent endovascular stent-graft repair. MDCT angiography was used in all patients to provide preprocedure evaluation and measurements. In particular it is necessary to evaluate the proximal and distal landing zones of the stent-graft. All EVGs in our series were placed successfully. Conversion to open surgery was never required. Six patients (10.7%) died early after the stent-graft deployment. During follow-up four more patients died. The endoleak rate was 16.7% (no. 10 pt). We did not observe any case of paraplegia. The present study shows the efficacy of EVG in the long-term follow-up, with an overall survival of 82.1%, which is comparable to that reported in recent studies. In conclusion this technique is emerging as an alternative approach in the treatment of TAD because this approach offers a less invasive therapeutic option to standard surgical techniques, even in patients who have associated diseases that make them poor surgical candidates.

  8. Aortic dissection in children and adolescents with Turner syndrome: risk factors and management recommendations.

    2015-07-01

    There is a general lack of awareness of the risk of aortic dissection in Turner syndrome (TS) from both patients with TS and their physicians. Patients often ignore symptoms for up to 24 h before seeking medical advice, significantly increasing their risk of death. A clinical profile of those at risk of dissection is emerging and includes the presence of congenital heart defects, aortic dilatation and hypertension. MRI has revolutionised the visualisation of cardiovascular anatomy in TS but remains underutilised, especially in children and adolescents, and there is currently little guidance on blood pressure (BP) assessment or hypertension management. Children and adolescents with TS at risk of dissection could be easily identified by timely imaging and BP assessment. This would allow medical management or surgical intervention to be put in place to reduce the risk of this major, and often fatal, complication. Since guidance is lacking, we have reviewed the literature on the risk factors for dissection in TS during childhood and adolescence, and make recommendations on the assessment and management of these patients.

    Mutations in ACTA2 predispose to thoracic aortic aneurysms and dissection as well as coronary artery and cerebrovascular disease. Here we examined the risk of aortic dissections, stroke and myocardial infarct with pregnancy in women with ACTA2 mutations. Of the 53 women who had a total of 137 pregnancies, eight had aortic dissections in the third trimester or the postpartum period (6% of pregnancies). One woman also had a myocardial infarct that occurred during pregnancy that was independent of her aortic dissection. Compared to the population-based frequency of peripartum aortic dissections of 0.6%, the rate of peripartum aortic dissections in women with ACTA2 mutations is much higher (8 out of 39; 20%). Six of these dissections initiated in the ascending aorta (Stanford type A), three were fatal. Three women had ascending aortic dissections at diameters less that 5.0 cm (range 3.8-4.7 cm). Aortic pathology showed mild to moderate medial degeneration of the aorta in three women. Of note, five of the women had hypertension either during or before the pregnancy. In summary, the majority of women with ACTA2 mutations did not have aortic or other vascular complications with pregnancy. However, these findings show that pregnancy is associated with significant risk for aortic dissection in women with ACTA2 mutations. Women with ACTA2 mutations who are planning to get pregnant should be counseled about this risk of aortic dissection, and proper clinical management should be initiated to reduce this risk.

    A 13-year-old boy presented with severe systemic hypertension. His upper limb blood pressure measured 190/100 mm Hg and lower limb blood pressure measured 98/64 mm Hg. The brachial pulses were bounding and femoral pulses were not palpable. Echocardiography and magnetic resonance angiography confirmed middle aortic syndrome. There was severe diffuse thoraco-abdominal coarctation with continuous Doppler run-off. Cardiac catheterization was undertaken and using a retrograde approach two Advanta V12 stents were implanted in the complex thoraco-abdominal coarctation. The gradient across the coarctation was reduced from 80 to 40 mm Hg gradient with a significant improvement in the luminal diameter of the aorta. His upper limb blood pressure reduced to 142/78 mm Hg six weeks later.

    Acute respiratory distress syndrome is a disease of acute onset characterized by hypoxemia and infiltrates on chest radiographs that affects both adults and children of all ages. It is an important cause of respiratory failure in pediatric intensive care units and is associated with significant morbidity and mortality. Nevertheless, until recently, the definitions and diagnostic criteria for acute respiratory distress syndrome have focused on the adult population. In this article, we review the evolution of the definition of acute respiratory distress syndrome over nearly five decades, with a special focus on the new pediatric definition. We also discuss recommendations for the implementation of mechanical ventilation strategies in the treatment of acute respiratory distress syndrome in children and the use of adjuvant therapies.

    Highly active antiretroviral treatment (HAART) has considerably increased the life expectancy of patients infected with HIV. Coronary artery disease is a leading cause of mortality in patients infected with HIV. This is primarily attributed to their increased survival, HAART-induced metabolic derangements, and to HIV itself. The pathophysiology of atherosclerosis in HIV is both multifactorial and complex – involving direct endothelial injury and dysfunction, hypercoagulability, and a significant contribution from traditional cardiac risk factors. The advent of HAART has since heralded a remarkable improvement in outcomes, but at the expense of other unforeseen issues. It is thus of paramount importance to swiftly recognize and manage acute coronary syndromes in HIV-infected patients to attenuate adverse complications, which should translate into improved clinical outcomes.

    Nuclear myocardial perfusion imaging is very effective in the evaluation of patients with suspicious acute coronary syndrome (ACS), for adequate diagnosis and treatment. There have been many clinical evidences to support the efficacy and cost-effectiveness. In addition, many authoritative guidelines support the utility of myocardial perfusion imaging in ACS with an appropriate diagnostic protocol. However, with the development of other cardiac imaging modalities, the choice of modality for the diagnosis of suspicious ACS now depends on the availability of each modality in each institute. Newly developed imaging technologies, especially including molecular imaging, are expected to have great potential not only for diagnosis but also for primary, secondary, and tertiary prevention of ACS.

    Full Text Available Acute respiratory distress syndrome (ARDS is a common complication of many diseases. Its polyetiological pattern determines the specific features of lung morphological changes and the clinical course of ARDS. Objective: to analyze the pathogenesis of ARDS in the context of the general pathological processes underlying its development. Material and methods. More than 200 lungs from the people who had died from severe concomitant injury or ARDS-complicated pneumonia were investigated. More than 150 rat experiments simulated various types of lung injury: ventilator-induced lung injury with different ventilation parameters; reperfusion injuries (systemic circulation blockade due to 12-minute vascular fascicle ligation, followed by the recovery of cardiac performance and breathing; microcirculatory disorder (injection of a thromboplastin solution into the jugular vein; blood loss; betaine-pepsin aspiration; and closed chest injury. Different parts of the right and left lungs were histologically examined 1 and 3 hours and 1 and 3 days after initiation of the experiment. Lung pieces were fixed in 10% neutral formalin solution and embedded in paraffin. Histological sections were stained with hematoxylin and eosin and using the van Gieson and Weigert procedures; the Schiff test was used. Results. The influence of aggression factors (trauma, blood loss, aspiration, infection, etc. results in damage to the lung and particularly air-blood barrier structures (endothelium, alveolar epithelium, their basement membrane. In turn the alteration of cellular and extracellular structures is followed by the increased permeability of hemomicrocirculatory bed vessels, leading to the development of non-cardiogenic (interstitial, alveolar pulmonary edema that is a central component in the pathogenesis of ARDS. Conclusion. The diagnosis of the early manifestations of ARDS must account for the nature of an aggression factor, the signs confirming the alteration of the lung

    Full Text Available Objective: to define the specific features of the course of acute respiratory distress syndrome (ARDS in puer-peras with a complicated postpartum period. Subjects and methods. Sixty-seven puerperas with ARDS were examined. Group 1 included 27 puerperas with postpartum ARDS; Group 2 comprised 10 puerperas who had been treated in an intensive care and died; Group 3 consisted of nonobstetric patients with ARDS of various genesis (a control group. Results. In obstetric patients, the baseline oxygenation index was significantly lower than that in the control group. However, Group 1 patients showed a rapid increase in PaO2/FiO2 on days 3—4 of treatment. In the control group, the changes occurred later — on days 5—6. The baseline alveolar-arterial oxygen difference was significantly higher in the obstetric patients than that in the controls. In Group 1, AaDpO2 drastically decreased on days 3—4, which took place in parallel with an increase in the oxygenation index. At the beginning of the study, pulmonary shunting was high in the group of survivors, deceased, and controls. In Group 1, the shunting decreased on days 3—4 whereas in the control group this index normalized later — only by days 6—7. In Group 1, compliance remained lower throughout the observation, but on day 7 there was a significant difference in this index between the deceased, survivors, and controls. Conclusion. Thus, more severe baseline pulmonary gas exchange abnormalities are observed in obstetric patients than in general surgical and traumatological patients; the oxygenation index, alveolar-arterial oxygen difference, and pulmonary shunting index more rapidly change in patients with severe obstetric disease in its favorable course than in general surgical and traumatological patients; throughout the observation, thoracopulmonary compliance was less in obstetric patients than in the controls. Key words: acute respiratory distress syndrome, puerperium.

    Full Text Available Context: A cervicofacial pain and foreign body sensation in pharynx associated with styloid process elongation is called Eagle syndrome. Typically, this syndrome is provoked by tonsillectomy or trauma. We report the first case of acute parotitis-induced Eagle syndrome. Case Report: A 65-year-old woman presented with right facial pain. CT scan of neck revealed asymmetric enhancement of the right parotid gland compatible with acute parotitis. All inflammation was resolved with antibiotics. However, the patient complained of pain in right mandibular region out of proportion to inflammation. Review CT found to have an asymmetrically long right styloid process measures. The diagnosis of acute parotitis-induced Eagle syndrome was established. Conclusion: Physicians should have a high index of suspicion for Eagle syndrome in patients with atypical neck pain and elongated styloid process since another significant manifestation of Eagle syndrome is carotid artery compression leading to recurrent syncope or stroke.

    2007-01-01

    Full Text Available Tumour Lysis syndrome (TLS is characterized by the massive destruction of tumoral cells and the release in the extracellular space of their content. While TLS may occur spontaneously before treatment, it usually develops shortly after the initiation of cytotoxic chemotherapy. These metabolites can overwhelm the homeostatic mechanisms and cause hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia. Moreover, TLS may lead to an acute renal failure (ARF. In addition to the hospital mortality induced by the acute renal failure itself, development of an ARF may preclude optimal cancer treatment. Therefore, prevention of the acute renal failure during acute tumor lysis syndrome is mandatory. The objective of this review is to describe pathophysiological mechanisms leading to acute tumor lysis syndrome, clinical and biological consequences of this syndrome and to provide up-to-date guidelines to ensure prevention and prompt management of this syndrome.

    The acute respiratory distress syndrome (ARDS) is currently one of the most important critical entities given its high incidence, rate of mortality, long-term sequelae and non-specific pharmacological treatment. The histological hallmark of ARDS is diffuse alveolar damage (DAD). Approximately 50% of ARDS patients present DAD, the rest is made up of a heterogeneous group of histological patterns, many of which correspond to a well-recognized disease. For that reason, if these patterns could be diagnosed, patients could benefit from a treatment. Recently, the effect of DAD in clinical and analytical evolution of ARDS has been demonstrated, so the classical approach to ARDS as an entity defined solely by clinical, radiological and gasometrical variables should be reconsidered. This narrative review aims to examine the need to evolve from the concept of ARDS as a syndrome to ARDS as a specific disease. So we have raised 4 critical questions: a) What is a disease?; b) what is DAD?; c) how is DAD considered according to ARDS definition?, and d) what is the relationship between ARDS and DAD?

    Patients with 47, XXY karyotype (Klinefelter syndrome) appear to have increased risk of developing cancer, especially male breast cancer, germ cell tumours and non Hodgkin lymphomas, but rarely acute myeloid leukaemia. We report a patient with acute basophilic leukaemia with 47, XXY karyotype in both the tumour and constitutional cells. Acute basophilic leukaemia is very rare disease comprising less than 1% of all acute myeloid leukaemias. Morphological characteristic of leukaemic blast cells is moderately basophilic cytoplasm containing a variable number of coarse basophilic granules. The most characteristic cytochemical reaction is metachromatic positivity with toluidine blue. Blast are myeloperoxidase negative. Also leukemic blasts express myeloid and monocyte markers. There is no consistent chromosomal abnormality identified in this leukaemia. This is the first reported case of acute basophilic leukaemia in patient with Klinefelter syndrome. In this article the medical history of the patient is given and the possible connection between Klinefelter syndrome and acute myeloid leukaemia is discussed.

    Full Text Available Prone positioning has been used for many years in patients with acute lung injury (ALI/acute respiratory distress syndrome (ARDS, with no clear benefit for patient outcome. Meta-analyses have suggested better survival in patients with an arterial oxygen tension (PaO2/inspiratory oxygen fraction (FIO2 ratio <100 mmHg. A recent randomised controlled trial was performed in ARDS patients after a 12–24 h stabilisation period and severity criteria (PaO2/FIO2 <150 mmHg at a positive end-expiratory pressure ≥5 cmH2O. This trial has demonstrated a significant reduction in mortality from 32.8% in the supine group to 16% in the prone group (p<0.001. The reasons for this dramatic effect are not clear but probably involves a reduction in ventilator-induced lung injury due to prone positioning, for which there is ample evidence in experimental and clinical studies. The aims of this article are to discuss: the rationale of prone positioning in patients with ALI/ARDS; the evidence of its use based on trial analysis; and the limitations of its use as well as the current place of prone positioning in the management of patients with ALI/ARDS. From the currently available data, prone positioning should be used as a first-line therapy in patients with severe ALI/ARDS.

    Full Text Available Objective: The aim was to find the incidence of acute encephalitis syndrome (AES secondary to scrub infection and to observe the clinical, biochemical, radiological profile, and outcomes in these patients. Materials and Methods: A total of 20 consecutive patients of AES were evaluated for scrub infection using scrub typhus immunoglobulin M enzyme linked immuno-sorbant assay positivity along with the presence or absence of an eschar. Clinical profile, routine laboratory tests, cerebrospinal fluid (CSF analysis, and neuroimaging were analyzed. Patients were treated with doxycycline and followed-up. Results: Among 20 consecutive patients with AES, 6 (30% were due to scrub infection. They presented with acute onset fever, altered sensorium, seizures. "Eschar" was seen in 50% of patients. CSF done in two of them was similar to consistent with viral meningitis. Magnetic resonance imaging brain revealed cerebral edema, bright lesions in the putamen and the thalamus on T2-weighted and fluid-attenuated inversion recovery sequences. Renal involvement was seen in all patients. All patients responded well to oral doxycycline. Conclusion: AES is not an uncommon neurological presentation following scrub typhus infection. It should be suspected in all patients with fever, altered sensorium, and renal involvement. Oral doxycycline should be started as early as possible for better outcomes.

  9. Echocardiographic detection of intimo-intimal intussusception in a patient with acute Stanford type A aortic dissection

    2015-01-01

    Full Text Available Intimo-intimal intussusception is a very rare and unusual complication of type A dissections, typically noted on  TEE exam. It has been reported in a few cases in the cardiothoracic surgical and radiology literature, and even more rarely in the cardiac anesthesia/TEE literature. This uncommon variation occurs in severe, acute, type A dissections when the ascending aortic intima circumferentially strips and detaches from the media and forms a tube-like structure which may either prolapse antegrade into the ascending aortic lumen or retrograde into the left ventricular (LV outflow tract and LV cavity. Antegrade intussusceptions may be severe enough to partially or completely occlude the ostia of the innominate, left common carotid, and left subclavian arteries producing acute neurologic symptoms. Retrograde intussusceptions may severely impair LV filling in diastole, can worsen aortic insufficiency, mitral regurgitation, as well as produce occlusion of the coronary ostia and acute coronary ischemia. Here, we describe the incidental finding of a retrograde intussusception that was not visualized on computed tomography scan but by intraoperative TEE examination, in a patient with a severe, extensive type A dissection.

    BACKGROUND The aim of our study was to investigate the P-wave dispersion from standard electrocardiograms (ECGs) in patients with acute myocardial infarction (AMI) after cardiac rehabilitation (CR) and determine its relation to arterial stiffness. METHODS This is a prospective study included 33 patients with AMI and successfully re-vascularized by percutaneous coronary intervention (PCI) underwent CR. Left ventricular ejection fraction (LVEF) was measured by biplane Simpson’s method. Left atrium (LA) volume was calculated. The maximum and minimum durations of P-waves (Pmax and Pmin, respectively) were detected, and the difference between Pmax and Pmin was defined as P-wave dispersion (Pd = Pmax-Pmin). Aortic elasticity parameters were measured. RESULTS LVEF was better after CR. The systolic and diastolic blood pressures decreased after CR, these differences were statistically significant. With exercise training, LA volume decreased significantly. Pmax and Pd values were significantly shorter after the CR program. The maximum and minimum P-waves and P-wave dispersion after CR were 97 ± 6 ms, 53 ± 5 ms, and 44 ± 5 ms, respectively. Aortic strain and distensibility increased and aortic stiffness index was decreased significantly. Aortic stiffness index was 0.4 ± 0.2 versus 0.3 ± 0.2, P = 0.001. Aortic stiffness and left atrial volume showed a moderate positive correlation with P-wave dispersion (r = 0.52, P = 0.005; r = 0.64, P < 0.001, respectively). CONCLUSION This study showed decreased arterial stiffness indexes in AMI patient’s participated CR, with a significant relationship between the electromechanical properties of the LA that may raise a question of the preventive effect of CR from atrial fibrillation and stroke in patients with acute myocardial infarction.

    Background Acute kidney injury (AKI) is common after surgery for acute aortic dissection (AAD) and increases in-hospital and long-term mortality. However, few data exist on the clinical and prognostic relevance of early preoperative AKI in patients with type A AAD. We aimed to determine the incidence and predictors of preoperative AKI and the impact of AKI on in-hospital outcomes in patients with type A AAD. Methods From May 2009 to June 2014, we retrospectively enrolled 178 patients admitted to our hospital within 48 h from symptom onset and receiving open surgery for type A AAD. The patients were divided into no AKI and AKI groups and staged with AKI severity according to the KDIGO criteria before surgery. Results AKI occurred in 41 patients (23.0%). The incidence of in-hospital complications was significantly higher in patients with preoperative AKI compared to no AKI (41.5% vs. 9.5%, P < 0.001), including renal infarction (7.3% vs. 0, P = 0.012), and it increased with AKI severity (Ptrend < 0.001). Patients with AKI had higher in-hospital mortality compared with patients without AKI, although no significant difference was found (14.6% vs. 5.1%, P = 0.079). Multivariate analysis indicated that male gender, diastolic blood pressure on admission and bilateral renal artery involvement were independent predictors of preoperative AKI in patients with type A AAD. Conclusions Early AKI before surgery was common in patients with type A AAD, and was associated with increased in-hospital complications. Male gender, diastolic blood pressure on admission and bilateral renal artery involvement were major predictors for preoperative AKI. PMID:27781058

    Mesenteric traction syndrome consists of sudden tachycardia, hypotension, and cutaneous hyperemia, and frequently occurs during mesenteric traction in patients undergoing abdominal aortic aneurysm (AAA) reconstructive surgery. The etiology and clinical impact of this phenomenon are unknown, but the symptoms suggest a release of vasoactive materials from the mesenteric vascular bed. Thirty-one patients who underwent AAA surgery were studied. Mesenteric traction was accompanied by a decrease in systolic (p = 0.005) and diastolic (p less than 0.05) blood pressures, and in systemic vascular resistance (p less than 0.005), and was accompanied by an increase in heart rate (HR) (p less than 0.005), and cardiac output (p = 0.01). These hemodynamic changes coincided with an increase (p less than 0.001) in plasma concentrations of 6-keto-prostaglandin F1 (6-K-PGF1). No apparent change was found in prostaglandin E2, thromboxane B2, and histamine concentrations. The concentration of 6-K-PGF1 was correlated with diastolic blood pressure (r = -0.52, p less than 0.005) and HR (r = 0.65, p less than 0.001). Cutaneous hyperemia was observed in 58% of the patients. In an additional six patients, who had taken aspirin daily before AAA surgery, no significant changes were observed in the hemodynamic measurements or 6-K-PGF1 concentrations. These data suggest that mesenteric traction syndrome may be mediated at least in part by a selective release of prostacyclin.

    The acute respiratory distress syndrome (ARDS) was defined in 1994 by the American-European Consensus Conference (AECC); since then, issues regarding the reliability and validity of this definition have emerged. Using a consensus process, a panel of experts convened in 2011 (an initiative of the European Society of Intensive Care Medicine endorsed by the American Thoracic Society and the Society of Critical Care Medicine) developed the Berlin Definition, focusing on feasibility, reliability, validity, and objective evaluation of its performance. A draft definition proposed 3 mutually exclusive categories of ARDS based on degree of hypoxemia: mild (200 mm Hg Definition was empirically evaluated using patient-level meta-analysis of 4188 patients with ARDS from 4 multicenter clinical data sets and 269 patients with ARDS from 3 single-center data sets containing physiologic information. The 4 ancillary variables did not contribute to the predictive validity of severe ARDS for mortality and were removed from the definition. Using the Berlin Definition, stages of mild, moderate, and severe ARDS were associated with increased mortality (27%; 95% CI, 24%-30%; 32%; 95% CI, 29%-34%; and 45%; 95% CI, 42%-48%, respectively; P definition, the final Berlin Definition had better predictive validity for mortality, with an area under the receiver operating curve of 0.577 (95% CI, 0.561-0.593) vs 0.536 (95% CI, 0.520-0.553; P Definition for ARDS addresses a number of the limitations of the AECC definition. The approach of combining consensus discussions with empirical evaluation may serve as a model to create more accurate, evidence-based, critical illness syndrome definitions and to better inform clinical care, research, and health services planning.

    Acute coronary syndromes are a frequent manifestation of a coronary artery disease, usually being associated with chest pain and presenting as a medical emergency. Since a considerable number of patients with chest pain, however, have a non cardiac etiology of trier pain, properly triaging these patients represents a diagnostic challenge for physicians in the emergency department. As the available diagnostic procedures have limited accuracy, many different diagnostic strategies have been evaluated. Among these, radionuclide myocardial perfusion imaging (MPI) at rest or in combination with stress procedures has been investigated in many trails. MPI has been proven to be useful, especially in a patient population with a low to intermediate probability of an ischemic event. Perfusion scintigraphy has a high sensitivity in the detection of myocardial infarction and reveals an excellent negative predictive value, allowing a safe discharge strategy of patients with a negative scan result. Moreover, it enables risk stratification and provides incremental and independent prognostic information regarding short to long term future cardiac adverse events. Several cost effectiveness studies have shown that perfusion imaging leads to lower overall direct costs, mainly by a reduction of unnecessary hospital admissions and diagnostic angiograms, without worsening of the clinical outcome of these patients. As a possible study endpoint, myocardial perfusion imaging in the acute setting enables the quantification of salvaged myocardium and therefore the evaluation of treatment efficacy. Besides perfusion agents, several infarcts avid radiopharmaceuticals have been developed, which in part show promising results. However, larger randomized trials evaluating these tracers in clinical settings are needed to warrant routine clinical application.

    A 69-year-old male experienced monocular formed visual hallucinations after occlusion of the right eye following resection of eyelid basal cell carcinoma and reconstruction with a Hughes procedure (tarsoconjunctival flap). His symptoms included recurrent, well-defined, organized, complex, formed images of small children playing in the snow. These visual phenomena occurred only in the occluded eye, began several hours after surgery, and recurred intermittently several times daily for 4 days, lasting several minutes with each occurrence. The patient retained insight into the false nature of the images throughout the duration of his symptoms, and the hallucinations resolved spontaneously while the flap was still in place. To our knowledge, this is the first reported case of Charles Bonnet Syndrome (CBS) following a Hughes procedure in a patient with normal visual acuity in the non-occluded fellow eye. Unlike other reported cases of acute onset CBS following transient monocular occlusion, hallucinations in the occluded eye remitted prior to restoration of vision in the occluded eye. Ophthalmologists should be aware of the potential for CBS following even transient monocular occlusion and should consider warning patients about its potential to occur.

    The authors evaluated the clinical and physiological effects of kinetic therapy (KT) in the treatment of acute respiratory distress syndrome (ARDS). Forty-six patients with ARDS underwent successive postural positioning in accordance with two regimens: 1) lateral, prone, contralateral, supine positions; 2) prone, lateral, contralateral, supine positions. The criterion for changing each position was the change in monitoring indices: SpO2, PaO2, and thoracopulmonary compliance (C). KT was performed until a respirator was withdrawn from the patient. In 25 patients, each maneuver of positioning was made during 30-minute propofol sedation. The control group included 24 patients with ARDS who received neither KT nor propofol sedation. KT caused a decrease in Vd/Vt, Qs/Qt and an increase in PaO2/FiO2 and C was more intensive, as compared with the control group. The duration of the patient's prone position was 3.2-0.7 hours and that of the supine position was 3.4-0.8 hours. The right and left lateral positions lasted 1.1-0.2 and 1.3-0.2 hours, respectively. KT regimen 1 was found to be more effective than KT regimen 2. Propofol sedation enhanced the efficiency of KT. The latter reduced death rates in patients with ARDS.

    Severe acute respiratory syndrome (SARS) first emerged in Guangdong province,China in November2002.During the following 3 months,it spread rapidly across the world,resulting in approximately 800 deaths.In 2004,subsequent sporadic cases emerged in Singapore and China.A novel coronavims,SARS-CoV,was identified as the etiological agent of SARS.1,2 This virus belongs to a family of large,positive,single-stranded RNA viruses.Nevertheless,genomic characterization shows that the SARS-CoV is only moderately related to other known coronaviruses.3 In contrast with previously described coronaviruses,SARS-CoV infection typically causes severe symptoms related to the lower respiratory tract.The SARS-CoV genome includes 14 putative open reading frames encoding 28 potential proteins,and the functions of many of these proteins are not known.4 A number of complete and partial autopsies of SARS patients have been reported since the first outbreak in 2003.The predominant pathological finding in these cases was diffuse alveolar damage (DAD).This severe pulmonary injury of SARS patients is caused both by direct viral effects and immunopathogenetic factors.5 Many important aspects of the pathogenesis of SARS have not yet been fully clarified.In this article,we summarize the most important mechanisms involved in the complex pathogenesis of SARS,including clinical characters,host and receptors,immune system response and genetic factors.

    Objective To study the pathological characteristics of severe acute respiratory syndrome (SARS) and its relationship to clinical manifestation. Methods Tissue specimens from 3 autopsies of probable SARS cases were studied by microscope, and the clinical data was reviewed.Results The typical pathological changes of lungs were diffuse hemorrhaging on the surface. A combination of serous, fibrinous and hemorrhagic inflammation was seen in most of the pulmonary alveoli with the engorgement of capillaries and detection of micro-thrombosis in some of these capillaries. Pulmonary alveoli thickened with interstitial mononuclear inflammatory infiltrates, suffered diffuse alveolar damage, experienced desquamation of pneumocytes and had hyaline-membrane formation, fibrinoid materials, and erythrocytes in alveolar spaces. There were thromboembolisms in some bronchial arteries. Furthermore, hemorrhagic necrosis was also evident in lymph nodes and spleen with the attenuation of lymphocytes. Other atypical pathological changes, such as hydropic degeneration, fatty degeneration, interstitial cell proliferation and lesions having existed before hospitalization were observed in the liver, heart, kidney and pancreas.Conclusion Severe damage to the pulmonary and immunological systems is responsible for the clinical features of SARS and may lead to the death of patients.

    Acute compartment syndrome of the lower extremity is a clinical condition that, although uncommon, is seen fairly regularly in modern orthopedic practice. The pathophysiology of the disorder has been extensively described and is well known to physicians who care for patients with musculoskeletal injuries. The diagnosis, however, is often difficult to make. In this article, we review the clinical risk factors of acute compartment syndrome of the lower extremity, identify the current concepts of diagnosis and discuss appropriate treatment plans. We also describe the Canadian medicolegal environment in regard to compartment syndrome of the lower extremity. PMID:20858378

    Full Text Available Acute intraoperative superior vena cava (SVC syndrome is an exceedingly rare complication in the cardiac surgical population. We describe the case of a 71-year-old female undergoing multi-vessel coronary artery bypass grafting who developed acute intraoperative SVC syndrome following internal thoracic artery harvest retractor placement. Her symptoms included severe plethora, facial engorgement and scleral edema, which was associated with hypotension and severe elevation of central venous pressure. Transesophageal echocardiography was crucial in the diagnosis, management, and optimal retractor placement ensuring adequate SVC flow. Potential causes of intraoperative SVC syndrome are reviewed as well as management options.

    In the absence of trauma, compartment syndrome of the thigh is rare. Several case reports have described compartment syndrome in the presence of trauma, comorbid medical conditions, and acute muscle overuse. Very few reports have demonstrated an acute onset of atraumatic thigh compartment syndrome. A 24-year-old man presented to the Emergency Department (ED) with a painful and swollen left thigh immediately after a night of dancing at a concert. He was found to have an elevated intracompartmental quadriceps pressure of 45 mm Hg in the ED, which led to his transfer to the operating room for an emergent fasciotomy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although acute, atraumatic compartment syndrome of the thigh is a rare entity, failure to diagnose it promptly can lead to muscle necrosis, permanent neurologic deficits, and amputation.

    Acute interstitial pneumonia (AIP) is a term used for an idiopathic form of acute lung injury characterized clinically by acute respiratory failure with bilateral lung infiltrates and histologically by diffuse alveolar damage (DAD), a combination of findings previously known as the Hamman-Rich syndrome. This review aims to clarify the diagnostic criteria of AIP, its relationship with DAD and acute respiratory distress syndrome (ARDS), key etiologies that need to be excluded before making the diagnosis, and the salient clinical features. Cases that meet clinical and pathologic criteria for AIP overlap substantially with those that fulfill clinical criteria for ARDS. The main differences between AIP and ARDS are that AIP requires a histologic diagnosis of DAD and exclusion of known etiologies. AIP should also be distinguished from "acute exacerbation of IPF," a condition in which acute lung injury (usually DAD) supervenes on underlying usual interstitial pneumonia (UIP)/idiopathic pulmonary fibrosis (IPF).

    The increasing population in older age will lead to greater numbers of them presenting with acute coronary syndromes (ACS). This has implications on global healthcare resources and necessitates better management and selection for evidenced-based therapies. The elderly are a high risk group with more significant treatment benefits than younger ACS. Nevertheless, age related inequalities in ACS care are recognised and persist. This discrepancy in care, to some extent, is explained by the higher frequency of atypical and delayed presentations in the elderly, and less diagnostic electrocardiograms at presentation, potentiating a delay in ACS diagnosis. Under estimation of mortality risk in the elderly due to limited consideration for physiological frailty, co-morbidity, cognitive/psychological impairment and physical disability, less input by cardiology specialists and lack of randomised, controlled trials data to guide management in the elderly may further confound the inequality of care. While these inequalities exist, there remains a substantial opportunity to improve age related ACS outcomes. The selection of elderly patients for specific therapies and medication regimens are unanswered. There is a growing need for randomised, controlled trial data to be more representative of the population and enroll those of advanced age with co-morbidity. A lack of reporting of adverse events, such as renal impairment post coronary angiography, in the elderly further limit risk benefit decisions. Substantial improvements in care of elderly ACS patients are required and should be advocated. Ultimately, these improvements are likely to lead to better outcomes post ACS. However, the improvement in outcome is not infinite and will be limited by non-modifiable factors of age-related risk.

    Studies in animals and in vitro and phase 2 studies in humans suggest that statins may be beneficial in the treatment of the acute respiratory distress syndrome (ARDS). This study tested the hypothesis that treatment with simvastatin would improve clinical outcomes in patients with ARDS. In this multicenter, double-blind clinical trial, we randomly assigned (in a 1:1 ratio) patients with an onset of ARDS within the previous 48 hours to receive enteral simvastatin at a dose of 80 mg or placebo once daily for a maximum of 28 days. The primary outcome was the number of ventilator-free days to day 28. Secondary outcomes included the number of days free of nonpulmonary organ failure to day 28, mortality at 28 days, and safety. The study recruited 540 patients, with 259 patients assigned to simvastatin and 281 to placebo. The groups were well matched with respect to demographic and baseline physiological variables. There was no significant difference between the study groups in the mean (±SD) number of ventilator-free days (12.6±9.9 with simvastatin and 11.5±10.4 with placebo, P=0.21) or days free of nonpulmonary organ failure (19.4±11.1 and 17.8±11.7, respectively; P=0.11) or in mortality at 28 days (22.0% and 26.8%, respectively; P=0.23). There was no significant difference between the two groups in the incidence of serious adverse events related to the study drug. Simvastatin therapy, although safe and associated with minimal adverse effects, did not improve clinical outcomes in patients with ARDS.

    Full Text Available Aims: A connection between psychiatric disorders (PDs and Type A acute aortic dissection (AAD has not been shown. The aim of this study was to define the psychological profile of patients treated for AAD, and to analyze the prevalence of PDs in their medical histories, in the immediate postoperative period, and at a mid-term follow-up. Patients and Methods: From March 2005 to October 2014, 240 consecutive patients underwent surgery for AAD. 60 patients (mean age 60+/-13 years; 43 males underwent psychiatric consultation postoperatively, and they represent the subjects of our retrospective study. Ascending aorta +/- arch replacement was performed in 43 patients, whereas the Bentall procedure +/- arch replacement was performed in 17. Data were retrospectively analyzed. Follow-ups were completed in 59 patients (mean duration 35+/-23 months. Results: PDs were present in the medical histories of 34 patients. Postoperatively, in 28 cases, a definitive diagnosis of PD (group PD was made in agreement with the diagnostic and statistical manual of mental disorders-IV criteria, including: Major depression (n=13, anxious-depressive syndrome (n=6, bipolar disorder Type 2 (n=4, panic attacks (n=2, paranoid schizophrenia (n=1, and anxiety (n=2. 32 patients without a definitive psychiatric diagnosis were classified as Group non-PD. In the postoperative period, clinical manifestations of PDs, including delirium, persistent spatio-temporal disorientation, and psychomotor agitation were evident in 22 patients (78% in group PD versus 8 patients (25% in group non-PD (P<0.0001. During follow-up, only one death for non-cardiac reasons occurred in group PD. There were no suicides; only 10 patients of group PD required PD treatment (P<0.0001 vs. early postoperative findings; 4 patients in group non-PD required PD treatment. Conclusion: Our findings suggest a strong relationship between PD and AAD. Because the psychiatric conditions appeared to be largely stable after

    Full Text Available Cardiovascular comorbidities to the Marfan syndrome may induce hemodynamic instability especially in the parturients during labor or delivery. For anesthesiologists, it is challenging to maintain hemodynamic stability during Cesarean section in those patients with Marfan syndrome. Remifentanil is an ultra-short-acting opioid with rapid onset and offset of action which provides cardiovascular stability during surgery. Together with remifentanil, the use of a laryngeal mask airway can reduce the risk of hypertensive response followed by tracheal intubation. We describe the successful administration of remifentanil and application of laryngeal mask airway for emergent Cesarean section performed under general anesthesia in a patient with Marfan syndrome complicated by ascending aortic aneurysm and heart failure. The use of remifentanil (loading dose of 1 μg/kg for 1 min, 2 min before induction; thereafter continuous infusion dose of 0.1 μg/kg/min was useful to maintain hemodynamic stability of the parturient throughout the surgery without neonatal respiratory depression.

    Acute respiratory distress syndrome is associated with poor clinical outcomes with a pooled mortality rate of approximately 40% despite best standards of care. Current therapeutic strategies are based upon improving oxygenation and pulmonary compliance while minimizing ventilator induced lung injury. It has been demonstrated that relative hypoxemia can be well tolerated and improvements in oxygenation do not necessarily translate into survival benefit. Cardiac failure, in particular right ventricular dysfunction, is commonly encountered in moderate to severe acute respiratory distress syndrome and is reported to be one of the major determinants of mortality. The prevalence rate of echocardiographically evident right ventricular dysfunction in acute respiratory distress syndrome varies across studies ranging from 22% to 50%. Although there is no definitive causal relationship between right ventricular dysfunction and mortality, severe right ventricular dysfunction is associated with increased mortality. Factors that can adversely affect right ventricular function include hypoxic pulmonary vasoconstriction, hypercapnia, and invasive ventilation with high driving pressure. It might be expected that early diagnosis of right ventricular dysfunction would be of benefit however, echocardiography markers (qualitative and quantitative) used to prospectively evaluate the right ventricle in acute respiratory distress syndrome have not been tested in adequately powered studies. In this review we examine the prognostic implications and pathophysiology of right ventricular dysfunction in acute respiratory distress syndrome and discuss available diagnostic modalities and treatment options. We aim to identify gaps in knowledge and directions for future research that could potentially improve clinical outcomes in this patient population.

    2006-01-01

    BACKGROUND:There is no report on case of severe acute hyperlipidemic pancreatitis after treatment of Sheehan's syndrome. METHODS: A 32-year-old female patient was diagnosed as having acute hyperlipidemic pancreatitis after treatment of Sheehan's syndrome, and treated with diet and lipid-lowering agents in early stage. RESULTS: Abdominal pain and fever of the patient resolved within a few days. She was subjected to diet and oral lipid-lowering therapy on the 4th day after admission. The disease did not recur during the follow-up for more than one year. CONCLUSIONS: Estrogen replacement therapy should be prescribed for Sheehan's syndrome. The serum level of triglyceride should be monitored and treatment should be given to prevent severe acute pancreatitis. Lipid-lowering therapy in early stage is the key step towards a complete recovery.

    The authors present a rare clinical case of a woman who developed Gerstmann's syndrome following an acute Herpes simplex viral encephalitis. Clinical observation and laboratory evaluation were performed during the acute phase of the disease. After that the follow-up continued for one-year period. The localization of the pathologic process was determined by computerized tomography, conducted periodically. The characteristics of the clinical picture are interpreted in the context of the contemporary concepts of the topical diagnosis of Gerstmann's syndrome. The possibility of a sudden onset of acute Herpes simplex viral encephalitis without a preceding febrile-intoxication syndrome is worth noting. Conclusions are drawn stressing the need of an early etiologic treatment and the importance of the rehabilitation activities during the convalescence period.

  9. Tachyarrhythmias, bradyarrhythmias and acute coronary syndromes

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available The incidence of bradyarrhythmias in patients with acute coronary syndrome (ACS is 0.3% to 18%. It is caused by sinus node dysfunction (SND, high-degree atrioventricular (AV block, or bundle branch blocks. SND presents as sinus bradycardia or sinus arrest. First-degree AV block occurs in 4% to 13% of patients with ACS and is caused by rhythm disturbances in the atrium, AV node, bundle of His, or the Tawara system. First- or second-degree AV block is seen very frequently within 24 h of the beginning of ACS; these arrhythmias are frequently transient and usually disappear after 72 h. Third-degree AV blocks are also frequently transient in patients with infero-posterior myocardial infarction (MI and permanent in anterior MI patients. Left anterior fascicular block occurs in 5% of ACS; left posterior fascicular block is observed less frequently (incidence < 0.5%. Complete bundle branch block is present in 10% to 15% of ACS patients; right bundle branch block is more common (2/3 than left bundle branch block (1/3. In patients with bradyarrhythmia, intravenous (IV atropine (1-3 mg is helpful in 70% to 80% of ACS patients and will lead to an increased heart rate. The need for pacemaker stimulation (PS is different in patients with inferior MI (IMI and anterior MI (AMI. Whereas bradyarrhythmias are frequently transient in patients with IMI and therefore do not need permanent PS, there is usually a need for permanent PS in patients with AMI. In these patients bradyarrhythmias are mainly caused by septal necrosis. In patients with ACS and ventricular arrhythmias (VTA amiodarone is the drug of choice; this drug is highly effective even in patients with defibrillation-resistant out-of-hospital cardiac arrest. There is general agreement that defibrillation and advanced life support is essential and is the treatment of choice for patients with ventricular flutter/fibrillation. If defibrillation is not available in patients with cardiac arrest due to VTA

    Acute compartment syndrome is an orthopedic surgical emergency and may result in devastating complications in the setting of delayed or missed diagnosis. Compartment syndrome has a variety of causes, including posttraumatic or postoperative swelling, external compression, burns, bleeding disorders, and ischemia-reperfusion injury. Rare cases of pediatric acute compartment syndrome in the setting of acute myeloid leukemia and, even less commonly, chronic myeloid leukemia have been reported. The authors report the first known case of pediatric acute compartment syndrome in a patient without a previously known diagnosis of chronic myeloid leukemia. On initial examination, an 11-year-old boy presented with a 2-week history of progressive left calf pain and swelling after playing soccer. Magnetic resonance imaging scan showed a hematoma in the left superficial posterior compartment. The patient had unrelenting pain, intermittent lateral foot parethesias, and inability to bear weight. Subsequently, he was diagnosed with acute compartment syndrome and underwent fasciotomy and evacuation of a hematoma. Laboratory results showed an abnormal white blood cell count of 440×10(9)/L (normal, 4.4-11×10(9)) and international normalized ratio of 1.3 (normal, 0.8-1.2). Further testing included the BCR-ABL1 fusion gene located on the Philadelphia chromosome, leading to a diagnosis of chronic myeloid leukemia. Monotherapy with imatinib mesylate (Gleevec) was initiated. This report adds another unique case to the growing literature on compartment syndrome in the pediatric population and reinforces the need to consider compartment syndrome, even in unlikely clinical scenarios.

    2016-03-01

    Full Text Available Coronary artery embolism is an uncommon cause of Acute Myocardial Infarction (AMI. Herein, we reported a 24-year-old male who was admitted with acute infero-posterior myocardial infarction and cerebral Transient Ischemic Attack (TIA. He had undergone mechanical Aortic Valve Replacement (AVR surgery 6 years ago. Surprisingly, the patient had decided to stop taking his medication (warfarin 20 days earlier without any medical advice. Coronary angiography revealed a thrombus located at the distal part of the left circumflex artery. Discontinuation of anticoagulant therapy in the presence of mechanical valve prosthesis, clinical evidence of coincidental TIA, and lack of atherosclerotic risk factors were highly suggestive of coronary thromboembolism as the cause of AMI. Overall, this case report emphasized the necessity of continuous education in patients with mechanical heart valves to prevent such undesired events.

    MELAS (mitochondrial cytopathy, encephalomyopathy, lactic acidosis and stroke-like episodes) is a syndrome in which signs and symptoms of gastrointestinal disease are uncommon if not rare. We describe the case of a young woman who presented as an acute surgical emergency, diagnosed as toxic megacolon necessitating an emergency total colectomy. MELAS syndrome was suspected postoperatively owing to persistent lactic acidosis and neurological symptoms. The diagnosis was later confirmed with histological and genetic studies. This case highlights the difficulties in diagnosing MELAS because of its unpredictable presentation and clinical course. We therefore recommend a high index of suspicion in cases of an acute surgical abdomen with additional neurological features or raised lactate.

    Ischemic heart disease is the leading cause of mortality worldwide. Due to advances in medicine in the past few decades, life expectancy has increased resulting in an aging population in developed and developing countries. Acute coronary syndrome causes greater morbidity and mortality in this group of older patients, which appears to be due to age-related comorbidities. This review examines the incidence and prevalence of acute coronary syndrome among older patients, examines current treatment strategies, and evaluates the predictors of adverse outcomes. In particular, the impact of frailty on outcomes and the need for frailty assessment in developing future research and management strategies among older patients are discussed.

    Severe acute respiratory syndrome (SARS) is a recently recognized infectious disease associated with severe morbidity and mortality. It presents with non-specific signs and symptoms and because no definitive laboratory test is readily available, it poses a great risk to healthcare workers as well as difficulty in quarantine. The global response has been coordinated and enthusiastic in trying to understand and control this disease. Severe acute respiratory syndrome poses a threat to the Caribbean because of easy and convenient travel and the vibrant tourist industry.

    Full Text Available Aortic dissection is one of the most common aortic emergencies affecting around 2000 Americans each year. It usually presents in the acute state but in a small percentage of patients aortic dissections go unnoticed and these patients survive without any adequate therapy. With recent advances in medical care and diagnostic technologies, aortic dissection can be successfully managed through surgical or medical options, consequently increasing the related survival rate. However, little is known about the optimal long-term management of patients suffering from chronic aortic dissection. The purpose of the present report is to review aortic dissection, namely its pathology and the current diagnostic tools available, and to discuss the management options for chronic aortic dissection, infiltrates or pleural effusions. Other tion. We report a patient in which chronic aortic dissection presented with recurring episodes of vomiting and also discuss the management plan of our patient who had a chronic aortic dissection as well as an underlying aortic aneurysm.

    2009-08-01

    Triple-rule-out (TRO) computed tomographic (CT) angiography can provide a cost-effective evaluation of the coronary arteries, aorta, pulmonary arteries, and adjacent intrathoracic structures for the patient with acute chest pain. TRO CT is most appropriate for the patient who is judged to be at low to intermediate risk for acute coronary syndrome (ACS) and whose symptoms may also be attributed to acute pathologic conditions of the aorta or pulmonary arteries. Although a regular cardiac rhythm remains an important factor in coronary CT image quality, newer CT scanners with 64 or more detector rows afford rapid electrocardiographically (ECG) gated imaging to provide high-quality TRO CT studies in patients with a heart rate of up to 80 beats per minute. Injection of iodinated contrast material ( 300 HU) and in the pulmonary arteries (> 200 HU). To limit radiation exposure, the TRO CT examination does not include the entire chest but is constrained to incorporate the aortic arch down through the heart. Scanning parameters, including prospective ECG tube current modulation and prospective ECG gating with the "step-and-shoot" technique, are tailored to reduce radiation exposure (optimally, 5-9 mSv). When performed with appropriate attention to timing and technique, TRO CT provides coronary image quality equal to that of dedicated coronary CT angiography and pulmonary arterial images that are free of motion artifact related to cardiac pulsation. In an appropriately selected emergency department patient population, TRO CT can safely eliminate the need for further diagnostic testing in over 75% of patients.

    2012-01-01

    Cauda equina syndrome is a well described state of neurologic compromise due to lumbosacral root compression. In most cases, it is due to a herniated disc, tumor, infection, or hematoma. We report a case of rapid lumbar synovial cyst expansion leading to acute cauda equina syndrome and compare it to similar cases in the literature. The patient is a 49-year-old woman with a history of chronic low back pain who developed cauda equina syndrome. Serial lumbar magnetic resonance imaging studies demonstrated a significant increase in the size of a lumbar synovial cyst over a 2 week interval. After an unsuccessful attempt to relieve her acute symptoms with computed tomography-guided cyst aspiration, an L4-5 posterior spinal decompression with excision of the synovial cyst was performed. Postoperatively the patient's perineal numbness, bladder incontinence, and associated pain complaints resolved. The only residual symptom at one month follow-up was continued numbness in the right lower limb in an L5 distribution. This report adds to 6 other well described similar cases found in the literature by illustrating several important points. First, a lumbar synovial cyst is a rare but possible cause of acute cauda equina syndrome. Second, magnetic resonance imaging is the test of choice to diagnose and characterize lumbar synovial cysts; serial imaging can detect fluctuations in cyst size. Third, percutaneous treatment of lumbar synovial cysts is variable in efficacy and proved to be unsuccessful in our patient. Finally, surgical management has shown high success rates for symptomatic cysts. Specifically, in the setting of acute cauda equina syndrome secondary to a lumbar synovial cyst, urgent surgical decompression has led to resolution of neurologic symptoms in most reported cases. A lumbar synovial cyst is an uncommon cause of acute cauda equina syndrome. Prompt diagnosis and treatment may lead to reduced morbidity associated with this condition.

    Marfan syndrome (MFS) is an autosomal-dominant disorder of connective tissue caused by mutations in the fibrillin-1 (FBN1) gene. Mortality is often due to aortic dissection and rupture. We investigated the structural and functional properties of the heart and aorta in a [Fbn1C1039G/+] MFS mouse using high-resolution ultrasound (echo) and optical coherence tomography (OCT). Echo was performed on 6- and 12-month old wild type (WT) and MFS mice (n = 8). In vivo pulse wave velocity (PWV), aortic root diameter, ejection fraction, stroke volume, left ventricular (LV) wall thickness, LV mass and mitral valve early and atrial velocities (E/A) ratio were measured by high resolution echocardiography. OCT was performed on 12-month old WT and MFS fixed mouse hearts to measure ventricular volume and mass. The PWV was significantly increased in 6-mo MFS vs. WT (366.6 ± 19.9 vs. 205.2 ± 18.1 cm/s; p = 0.003) and 12-mo MFS vs. WT (459.5 ± 42.3 vs. 205.3 ± 30.3 cm/s; pMarfan patients including significant aortic dilation, central aortic stiffness, LV systolic and diastolic dysfunction. This is the first demonstration of the direct measurement in vivo of pulse wave velocity non-invasively in the aortic arch of MFS mice, a robust measure of aortic stiffness and a critical clinical parameter for the assessment of pathology in the Marfan syndrome.

    Seven episodes of rhabdomyolysis with acute renal failure (ARF) have been observed in 6 patients treated with various short-acting tranquilizers and antidepressants. Clinical features usually included severe hyperthermia, diffuse hypertonicity with or without coma, circulatory failure or unstable blood pressure, and often acute respiratory failure. Serum CPK were always elevated. The type of ARF was prerenal failure without oliguria in 5/7 episodes, and acute tubular necrosis in 2/7 episodes, requiring hemodialyses in one patient. Three patients died. In any case, the tranquilizers and antidepressants responsible for this syndrome were stopped, and electrolyte disorders and acidosis were corrected. Associated acute circulatory failure, septicemia and/or acute hepatic failure required prompt therapy, and artificial ventilation was required in 4 instances. The further use of phenothiazines, butyrophenones, sulpiride and their derivatives should be avoided in any patient having developed such an accident, whose pathophysiology is similar to that described in malignant hyperthermia of various origin.

    Full Text Available Metabolic Syndrome (MS or insulin resistance syndrome is commonly defined as a group of risk factors or abnormalities associated with insulin resistance that markedly increased risk for both coronary heart disease and diabetes. Cardiovascular disease and all-cause mortality, even in the absence of baseline CVD and diabetes. Early identification, treatment and prevention of the metabolic syndrome present a major challenge for health care professionals facing an epidemic of overweight and sedentary lifestyle. AIMS AND OBJECTIVES To study the prevalence of metabolic syndrome in pts. with Acute Coronary Syndrome (ACS and its effect on hospital outcomes. MATERIALS AND METHODS Observational study in 55 cases (28 cases and 27 controls was conducted in Dr. BRAMH, Raipur and each patient was assessed with detailed clinical history and was also assessed for parameters of MS. The cases and controls were also followed up during their hospital stay for the presence of or development of heart failure, arrhythmias, shock and death. Chi square and ‘t’ test were used to analyse obtained data. RESULTS AND CONCLUSIONS In the present study sex ratio amongst the cases was (M:F 1.15:1 and 2.6:1 in controls. Maximum patients were between the ages of 50-60. Non-ST elevation MI was more common in patients with metabolic syndrome and they presented late to the hospital for treatment. Hypertension and fasting hyperglycemia are the most prevalent components of metabolic syndrome in patients of acute coronary syndrome. Our Study also suggests that hypertriglyceridemia is the most common lipid abnormality in patients of acute coronary syndrome. An increase in the incidence of heart failure was observed in patients with metabolic syndrome Cardiogenic shock is seen with increased frequency in patients with metabolic syndrome. Case fatalities were seen with equal frequency in both the groups, hence metabolic syndrome is not associated with increased case fatality while

    Because acute compartment syndrome is one of the few limb-threatening and life-threatening orthopaedic conditions and is difficult to diagnose, it is a frequent source of litigation. Understanding the factors that lead to plaintiff verdicts and higher indemnity payments may improve patient care by identifying common pitfalls. The VerdictSearch legal claims database was queried for the term "compartment syndrome." After 46 cases were excluded for missing information or irrelevancy, 139 cases were reviewed. The effects of plaintiff demographics, mechanism of injury, and complications were assessed. Of 139 cases, 37 (27%) were settled, 69 (50%) resulted in a defendant ruling, and 33 (24%) resulted in a plaintiff ruling. Juries were more likely to rule in favor of juvenile plaintiffs than adult patients (P = 0.002) and female plaintiffs than male plaintiffs (P = 0.008), but indemnity payments were not affected by the age or sex of the plaintiff. Plaintiffs who experienced acute compartment syndrome as a complication of surgery were more likely to win their suit and receive higher awards (P compartment syndrome if the patient was a woman or child or if acute compartment syndrome developed as a complication of a surgical procedure.

  2. Troponin elevation in conditions other than acute coronary syndromes

    Full Text Available Asli Tanindi, Mustafa CemriGazi University Faculty of Medicine, Department of Cardiology, Ankara, TurkeyAbstract: Acute coronary syndromes comprise a large spectrum of clinical conditions ranging from unstable angina pectoris to acute ST-elevation myocardial infarction. Chest pain is usually the major symptom of atherosclerotic heart disease; however, it may be challenging to diagnose correctly, especially in the emergency department, because of the ambiguous way that pain is characterized by some patients. Cardiac troponins are sensitive and specific biomarkers used in the diagnosis of myocardial infarction that are released into the bloodstream when cardiac myocytes are damaged by acute ischemia or any other mechanism. They are the cornerstone for the diagnosis, risk assessment, prognosis, and determination of antithrombotic and revascularization strategies. However, troponin elevation indicates the presence, not the mechanism, of myocardial injury. There are many clinical conditions other than myocardial infarction that cause troponin elevation; thus, the physician should be aware of the wide spectrum of disease states that may result in troponin elevation and have a clear understanding of the related pathophysiology to effectively make a differential diagnosis. This review focuses on causes of troponin elevation other than acute coronary syndromes.Keywords: cardiac troponin, troponin elevation without acute coronary syndrome, differential diagnosis

    Acute respiratory distress syndrome (ARDS) is a severe form of acute lung injury. It is a response to various diseases of variable etiology, including SARS-CoV infection. To date, a comprehensive study of the genomic physiopathology of ARDS (and SARS) is lacking, primarily due to the difficulty of finding suitable materials to study the disease process at a tissue level (instead of blood, sputa or swaps). Hereby we attempt to provide such study by analyzing autopsy lung samples from patient who died of SARS and showed different degrees of severity of the pulmonary involvement. We performed real-time quantitative PCR analysis of 107 genes with functional roles in inflammation, coagulation, fibrosis and apoptosis; some key genes were confirmed at a protein expression level by immunohistochemistry and correlated to the degree of morphological severity present in the individual samples analyzed. Significant expression levels were identified for ANPEP (a receptor for CoV), as well as inhibition of the STAT1 pathway, IFNs production and CXCL10 (a T-cell recruiter). Other genes unassociated to date with ARDS/SARS include C1Qb, C5R1, CASP3, CASP9, CD14, CD68, FGF7, HLA-DRA, IGF1, IRF3, MALAT-1, MSR1, NFIL3, SLPI, USP33, CLC, GBP1 and TAC1. As a result, we proposed to therapeutically target some of these genes with compounds such as ANPEP inhibitors, SLPI and dexamethasone. Ultimately, this study may serve as a model for future, tissue-based analyses of fibroinflammatory conditions affecting the lung.

    A large proportion of patients with coronary disease have metabolic syndrome, although the frequency and association of its different components are not well understood. The aim of this study was to determine the prevalence of metabolic syndrome and the combination of its components in a Spanish cohort of patients with acute coronary syndrome. Clinical histories of 574 inpatients with acute coronary syndrome in 6 tertiary hospitals were reviewed and the presence of metabolic syndrome and its components determined by applying Adult Treatment Panel III criteria. In a second step, the components of the metabolic syndrome were analyzed, excluding those patients with diabetes mellitus. The metabolic syndrome was present in 50.9% of patients and was more frequent in women than in men (66.3% vs. 47.3%; P<.001). The most prevalent component was carbohydrate metabolism disorder (85.3%), followed by low high-density lipoprotein cholesterol (HDLc) levels (80.5%). In nondiabetic patients, 34.6% had metabolic syndrome and the most prevalent component was low HDLc levels (86%), followed by high blood pressure and hypertriglyceridemia and, in fourth place, impaired fasting serum glucose levels. The metabolic syndrome has a high prevalence in patients with an acute coronary syndrome, especially in women. The most frequent components are hyperglycemia and low HDLc levels. After excluding diabetic patients, the most prevalent diagnostic criterion of metabolic syndrome was low HDLc levels. Full English text available from: www.revespcardiol.org.

    2012-08-01

    Full Text Available Abstract Acute lung injury and acute respiratory distress syndrome are clinical entities of multi-factorial origin frequently seen in traumatically injured patients requiring intensive care. We performed an unsystematic search using PubMed and the Cochrane Database of Systematic Reviews up to January 2012. The purpose of this article is to review recent evidence for the pathophysiology and the management of acute lung injury/acute respiratory distress syndrome in the critically injured patient. Lung protective ventilation remains the most beneficial therapy. Future trials should compare intervention groups to controls receiving lung protective ventilation, and focus on relevant outcome measures such as duration of mechanical ventilation, length of intensive care unit stay, and mortality.

    We assessed the incidence of coronary artery disease (CAD) during hospitalization after emergency surgery for a type A acute aortic dissection. A total of 123 patients underwent multi-slice computed tomography (MSCT) scans during an early stage after surgery. The patients were divided into two groups: group I consisted of 14 patients (11.4%) who had coronary artery stenosis of more than 75% on MSCT, and group II consisted of 109 patients (88.6%) who had no coronary lesions. The prevalence of diabetes, dyslipidemia and a smoking history was significantly higher in group I. Although the serum low-density lipoprotein cholesterol levels were similar, the high-density lipoprotein cholesterol (HDL) level was significantly lower in group I (36.4 ± 7.9 mg/dl) than in group II (49.6 ± 13.5 mg/dl, P = 0.0005). The maximum carotid intima-media thickness (IMT) was significantly thicker in group I (1.17 ± 0.37 mm) compared to group II (0.96 ± 0.33 mm, P = 0.0297). The logistic regression analysis detected that a carotid IMT over 1.1 mm (odds ratio 4.35, P = 0.0371) and HDL less than 40 mg/dl (odds ratio 3.90, P = 0.0482) were predictors for CAD. CAD screening should be recommended for patients with aortic dissection who have several atherosclerosis risk factors, even after emergency surgery.

    A 65-year-old man developed chest pain under cardiogenic shock. Coronary angiography revealed severe stenosis from the ostium of the left main coronary artery(LMCA) to the left anterior descending artery(LAD). Intravascular ultrasound(IVUS) identified a large hematoma that originated from the aorta and extended into the LAD, thereby compressing the true lumen. Type A aortic dissection(TAAD) that involved the LMCA was diagnosed by IVUS. Coronary stenting was performed via the LMCA to the proximal LAD, which resulted in coronary blood flow restoration and no further propagation of dissection. Elective surgical aortic repair was performed 2 wk after the stenting. LMCA stenting under IVUS guidance is effective for prompt diagnosis and precise stent deployment in patients with cardiogenic shock due to TAAD with LMCA dissection.

Most commonly, it is associated with connective tissue disorders, cardiac valve variants, or trauma. We present the case of a 23-year-old previously healthy woman, 36 weeks pregnant with a syncopal episode after dyspnea and vomiting. She subsequently developed cardiac arrest and underwent aggressive resuscitation, emergent thoracotomy, and cesarean delivery without recovery. On autopsy, she was found to have an aortic dissection of the ascending aorta. This case is presented to raise awareness and review the literature and the clinical approach to critical care for pregnant patients. [West J Emerg Med. 2011;12(4:571–574.

    2011-11-01

    Full Text Available Abstract Fortunately radiation accidents are infrequent occurrences, but since they have the potential of large scale events like the nuclear accidents of Chernobyl and Fukushima, preparatory planning of the medical management of radiation accident victims is very important. Radiation accidents can result in different types of radiation exposure for which the diagnostic and therapeutic measures, as well as the outcomes, differ. The clinical course of acute radiation syndrome depends on the absorbed radiation dose and its distribution. Multi-organ-involvement and multi-organ-failure need be taken into account. The most vulnerable organ system to radiation exposure is the hematopoietic system. In addition to hematopoietic syndrome, radiation induced damage to the skin plays an important role in diagnostics and the treatment of radiation accident victims. The most important therapeutic principles with special reference to hematopoietic syndrome and cutaneous radiation syndrome are reviewed.

    Acute respiratory distress syndrome occupies a great deal of attention in intensive care units. Despite ample knowledge of the physiopathology of this syndrome, the focus in intensive care units consists mostly of life-supporting treatment and avoidance of the side effects of invasive treatments. Although great advances in mechanical ventilation have occurred in the past 20 years, with a significant impact on mortality, the incidence continues to be high. Patients with acute respiratory distress syndrome, especially the most severe cases, often present with refractory hypoxemia due to shunt, which can require additional treatments beyond mechanical ventilation, among which is mechanical ventilation in the prone position. This method, first recommended to improve oxygenation in 1974, can be easily implemented in any intensive care unit with trained personnel. Prone position has extremely robust bibliographic support. Various randomized clinical studies have demonstrated the effect of prone decubitus on the oxygenation of patients with acute respiratory distress syndrome measured in terms of the PaO2/FiO2 ratio, including its effects on increasing patient survival. The members of the Respiratory Therapists Committee of the Sociedad Argentina de Terapia Intensiva performed a narrative review with the objective of discovering the available evidence related to the implementation of prone position, changes produced in the respiratory system due to the application of this maneuver, and its impact on mortality. Finally, guidelines are suggested for decision-making. PMID:27925054

    Hepatic retransplant constitutes 10-20% of all orthotopic hepatic transplants. The piggy-back technique was used in hepatectomy with conservation of the retrohepatic vena cava. A side-to-side cavo-cavostomy technique is described in the case of hepatic congestion or acute Budd Chiari syndrome post-transplant. This is an extremely serious condition and can result in death. We present the first case of hepatic retransplant performed in Hospital Hermanos Ameijeiras in a patient who received who received his first transplant due to non-resectable hepatocarcinoma and who required retransplant due to acute rejection and graft dysfunction. During retransplant, the Belghiti side-to-side anastomosis technique was used to resolve the acute Budd Chiari syndrome that presented itself. Post-surgical evolution at 18 months was satisfactory without evidence of complications of the graft. Acute Budd Chiari syndrome post-transplant can satisfactorily be resolved with the Belghiti technique, although it is preferable to take prophylactic measures to avoid it.

    Aortic intramural hemorrhage (IMH) is one of the disease processes that comprise the spectrum of acute aortic syndrome (AAS) with clinical manifestations and a mortality rate similar to those of classic aortic dissection (AD). However, IMH should be considered as a distinct disease entity rather than a precursor to classic dissection because of differences in their pathology, etiology, natural history, and imaging findings. Multidetector computed tomography (CT) is recommended as the first-line diagnostic imaging modality for IMH, but transesophageal echocardiography (TEE) and magnetic resonance imaging (MRI) are also helpful. There is still debate over the appropriate treatment of IMH. Medical treatment of type B IMH appears effective and safe, while surgical treatment is recommended for type A IMH. Thoracic endovascular aortic repair (TEVAR) is a promising treatment for selected patients, and more clinical evidence needs to be assembled.

    2016-02-01

    Acute respiratory distress syndrome (ARDS) is defined by acute diffuse inflammatory lung injury invoked by a variety of systemic or pulmonary insults. Despite medical progress in management, mortality remains 27% to 45%. Patients with ARDS should be managed with low tidal volume ventilation. Permissive hypercapnea is well tolerated. Conservative fluid strategy can reduce ventilator and hospital days in patients without shock. Prone positioning and neuromuscular blockers reduce mortality in some patients. Early management of ARDS is relevant to emergency medicine. Identifying ARDS patients who should be transferred to an extracorporeal membrane oxygenation center is an important task for emergency providers.

    Full Text Available Turner syndrome (TS, most frequently caused by X-monosomy (45,X, is characterized in part by cardiovascular abnormalities, including aortopathy and bicuspid aortic valve (BAV. There is a need for animal models that recapitulate the cardiovascular manifestations of TS. Extracellular matrix (ECM organization and morphometrics of the aortic valve and proximal aorta were examined in adult 39,XO mice (where the parental origin of the single X was paternal (39,XPO or maternal (39,XMO and 40,XX controls. Aortic valve morphology was normal (tricuspid in all of the 39,XPO and 40,XX mice studied, but abnormal (bicuspid or quadricuspid in 15% of 39,XMO mice. Smooth muscle cell orientation in the ascending aorta was abnormal in all 39,XPO and 39,XMO mice examined, but smooth muscle actin was decreased in 39,XMO mice only. Aortic dilation was present with reduced penetrance in 39,XO mice. The 39,XO mouse demonstrates aortopathy and an X-linked parent-of-origin effect on aortic valve malformation, and the candidate gene FAM9B is polymorphically expressed in control and diseased human aortic valves. The 39,XO mouse model may be valuable for examining the mechanisms underlying the cardiovascular findings in TS, and suggest there are important genetic modifiers on the X chromosome that modulate risk for nonsyndromic BAV and aortopathy.

    Full Text Available Strongyloidiasis is endemic in tropic and subtropic areas, but is currently seldom encountered in developed area like Taiwan. We present an elder man with acute respiratory distress syndrome complicating Strongyloides stercoralis hyperinfection. There was no significant clue initially for diagnosing this patient as having S. stercoralis hyperinfection. Neither peripheral eosinophilia nor significant hemoptysis was noted. Bronchoscopy played a critical role to define the unexpected cause of his progressive pulmonary infiltrates. The correct diagnosis was soon made by recognition of the worm in bronchioloalveolar lavage cytology, and specific treatment was initiated promptly. For a septic patient with progressive pulmonary infiltrates, bronchoscopic studies including cytology may be necessary for defining the cause. Hyperinfection strongyloidiasis should be considered as a cause of acute respiratory distress syndrome in immunocompromised patient, especially with the presence of chronic gastrointestinal symptoms.

    Acute compartment syndrome (ACS) of the limb refers to a constellation of symptoms, which occur following a rise in the pressure inside a limb muscle compartment. A failure or delay in recognising ACS almost invariably results in adverse outcomes for patients. Unrecognised ACS can leave patients with nonviable limbs requiring amputation and can also be life–threatening. Several clinical features indicate ACS. Where diagnosis is unclear there are several techniques for measuring intracompartmental pressure described in this review. As early diagnosis and fasciotomy are known to be the best determinants of good outcomes, it is important that surgeons are aware of the features that make this diagnosis likely. This clinical review discusses current knowledge on the relevant clinical anatomy, aetiology, pathophysiology, risk factors, clinical features, diagnostic procedures and management of an acute presentation of compartment syndrome.

    Full Text Available Introduction. Acute aortic dissection (AD is the most common life-threatening disorder affecting the aorta. Neurological symptoms are present in 17-40% of cases. The management of these patients is controversial. Case report. We presented a 37-year-old man admitted for complaining of left-sided weak-ness. Symptoms appeared two hours before admission. The patient had no headache, neither thoracic pain. Neurological examination showed mild confusion, left-sided hemiplegia, National Institutes of Health Stroke Scale (NIHSS score was 10. Ischemic stroke was suspected, brain multislice computed tomography (MSCT and angiography were performed and right intrapetrous internal carotid artery dissection noted. Subsequent color Doppler ultrasound of the carotid arteries showed dissection of the right common carotid artery (CCA. The patient underwent thoracic and abdominal MSCT aortography which showed ascending aortic dissection from the aortic root, propagating in the brachiocephalic artery and the right CCA. Digital subtraction angiography was performed subsequently and two stents were successfully implanted in the brachiocephalic artery and the right CCA prior to cardiac surgery, only 6 hours after admission. The ascending aorta was reconstructed with graft interposition and the aortic valve re-suspended. The patient was hemodynamically stable and with no neurologic deficit after surgery. Unfortinately, at the operative day 6, mediastinitis developed and after intensive treatment the patients died 35 days after admission. Conclusion. In young patients with suspected stroke and oscillatory neurological impairment urgent MSCT angiography of the brain and neck and/or Doppler sonography of the carotid and vertebral artery are mandatory to exclude carotid and aortic dissection. The prompt diagnosis permits urgent carotid stenting and cardiosurgery. To the best of our knowledge, this is the first published case of immediate carotid stenting in acute ischemic

    2014-01-01

    Full Text Available Endovascular aneurysm repair (EVAR is perhaps the most widely utilized surgical procedure for patients with large abdominal aortic aneurysms. This procedure is minimally invasive and reduces inpatient hospitalization requirements. The case involves a 72-year-old male who presented to the emergency department with right testicular ischemia two days following EVAR. Given the minimal inpatient hospitalization associated with this procedure, emergency physicians are likely to encounter associated complications. Ischemic and thromboembolic events following EVAR are extremely rare but require prompt vascular surgery intervention to minimize morbidity and mortality.

    2002-01-01

    Aorto-caval fistula (ACF) is a rare complication of abdominal aortic aneurysm. It occurs in 1-6% of cases. The classic diagnostic signs of an ACF (pulsatile abdominal mass with bruit and right ventricular failure) are present only in a half of the patients. The most common diagnostic imaging procedures like ultrasound and computed tomography often are not sufficient enough. This leads to the delay in diagnosis, which has a great impact on the results of operation. We report a case of a patient, who was treated before admission to the Clinic because of azotemia and oliguria suggesting renal failure.

    Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI), which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE), emotional distancing (EmD), dehumanization (De) and professional fulfillment (PF). The Lipp's Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    Full Text Available The purpose of the present investigation was to improve the outcomes of intensive care in patients with acute respiratory distress syndrome after cardiac surgery under extracorporeal circulation.Materials and methods. Respiratory therapy was analyzed in 43 patients with acute respiratory distress syndrome after surgery under extracorporeal circulation. According to the procedure of artificial ventilation (AV, the patients were divided into 2 groups: 1 those who had undergone routine tracheal intubation (n=23 AND 2 THOSE who had received noninvasive intubation through a nasal mask (n=20. The respiratory parameters, blood gas composition, central hemodynamic parameters, respiratory support time, and the pattern of complications were analyzed.Results. Noninvasive artificial ventilation permits one to make the patients active in earlier periods and take a spontaneous breath, recovers the respiratory index earlier, reduces the level of positive end-expiratory pressure, the frequency of infectious complications of the tracheobronchial tree, and length of stay in an intensive care unit as compared with endotracheal AV.Conclusion. The findings suggest that noninvasive AV is highly effective and yields better results of treatment in patients with acute respiratory distress syndrome.

    Despite a large volume of evidence supporting the use of dual antiplatelet therapy in patients with acute coronary syndrome, there remains major uncertainty regarding the optimal duration of therapy. Clinical trials have varied markedly in the duration of therapy, both across and within trials. Recent systematic reviews and meta-analyses suggest that shorter durations of dual antiplatelet therapy are superior because the avoidance of atherothrombotic events is counterbalanced by the greater risks of excess major bleeding with apparent increases in all-cause mortality with longer durations. These findings did not show significant heterogeneity according to whether patients had stable or unstable coronary heart disease. Moreover, the potential hazards and benefits may differ when applied to the general broad population of patients encountered in everyday clinical practice who have markedly higher bleeding and atherothrombotic event rates. Clinicians lack definitive information regarding the duration of therapy in patients with acute coronary syndrome and risk scores do not appear to be sufficiently robust to address these concerns. We believe that there is a pressing need to undertake a broad inclusive safety trial of shorter durations of therapy in real world populations of patients with acute coronary syndrome. The clinical evidence would further inform future research into strategies for personalised medicine. PMID:28249994

    2009-10-01

    Full Text Available We report a case of nephrotic syndrome and acute renal failure apparently induced by sunitinib. A 67-year-old man with a history of metastatic renal cell carcinoma presented with progressive kidney dysfunction with proteinuria, general edema, and body weight gain of 21 kg after undergoing 3 weeks of sunitinib therapy. The patient had taken no other over-the-counter medications, and all other possible causes of nephrotic syndrome were excluded. The Naranjo Adverse Drug Reaction Probability Scale score for this event was 6, indicating a high probability that the observed presentations were associated with use of the drug. However, despite the discontinuation of sunitinib, his condition deteriorated, and hemodialysis was initiated for respiratory distress. A renal biopsy was performed, which revealed ischemic acute tubular necrosis with minimal change nephropathy. In conclusion, nephrologists and oncologists should be aware that nephrotic syndrome with ischemic acute tubular necrosis is a possible adverse effect of sunitinib. For early diagnosis of this condition and to avoid renal damage, we recommend differential diagnosis of serum creatinine and proteinuria in patients undergoing sunitinib therapy.

Patients with Marfan syndrome (MFS whose lifetimes are extended may be encountered as acute abdomen (appendicitis cases apart from the obligatory reasons and emergencies arising naturally out of their disease, as in the case reported.Case presentation: In a 28-year-old Turkish male, arachnodactyly, pectus excavatum, kyphoscoliosis and, according to pulmonary roentgenogram, a density increase in the left apical field were detected. In addition, according to the echocardiographic examination, Ebstein’s anomaly, mitral valve prolapse, pulmonary hypertension, and inferior deficiency of mitral, aorta, and tricuspid valves were present. The patient was planned to be operated on with the prediagnosis of acute abdomen.Conclusion: Taking into consideration the pathologies that may accompany MFS and the probable future complications, the patients must be closely monitored during anesthesia applications and required measures should be taken beforehand.Keywords: Marfan syndrome, acute abdomen

  20. Network analysis reveals distinct clinical syndromes underlying acute mountain sickness.

    Directory of Open Access Journals (Sweden)

    David P Hall

    Full Text Available Acute mountain sickness (AMS is a common problem among visitors at high altitude, and may progress to life-threatening pulmonary and cerebral oedema in a minority of cases. International consensus defines AMS as a constellation of subjective, non-specific symptoms. Specifically, headache, sleep disturbance, fatigue and dizziness are given equal diagnostic weighting. Different pathophysiological mechanisms are now thought to underlie headache and sleep disturbance during acute exposure to high altitude. Hence, these symptoms may not belong together as a single syndrome. Using a novel visual analogue scale (VAS, we sought to undertake a systematic exploration of the symptomatology of AMS using an unbiased, data-driven approach originally designed for analysis of gene expression. Symptom scores were collected from 292 subjects during 1110 subject-days at altitudes between 3650 m and 5200 m on Apex expeditions to Bolivia and Kilimanjaro. Three distinct patterns of symptoms were consistently identified. Although fatigue is a ubiquitous finding, sleep disturbance and headache are each commonly reported without the other. The commonest pattern of symptoms was sleep disturbance and fatigue, with little or no headache. In subjects reporting severe headache, 40% did not report sleep disturbance. Sleep disturbance correlates poorly with other symptoms of AMS (Mean Spearman correlation 0.25. These results challenge the accepted paradigm that AMS is a single disease process and describe at least two distinct syndromes following acute ascent to high altitude. This approach to analysing symptom patterns has potential utility in other clinical syndromes.

    Full Text Available Abstract Background Abdominal aortic calcifications (AAC predict cardiovascular mortality. A new scoring model for AAC, the Morphological Atherosclerotic Calcification Distribution (MACD index may contribute with additional information to the commonly used Aortic Calcification Severity (AC24 score, when predicting death from cardiovascular disease (CVD. In this study we investigated associations of MACD and AC24 with traditional metabolic-syndrome associated risk factors at baseline and after 8.3 years follow-up, to identify biological parameters that may account for the differential performance of these indices. Methods Three hundred and eight healthy women aged 48 to 76 years, were followed for 8.3 ± 0.3 years. AAC was quantified using lumbar radiographs. Baseline data included age, weight, blood pressure, blood lipids, and glucose levels. Pearson correlation coefficients were used to test for relationships. Results At baseline and across all patients, MACD correlated with blood glucose (r2 = 0.1, P Conclusion Patterns of calcification identified by the MACD, but not the AC24 index, appear to contain useful biological information perhaps explaining part of the improved identification of risk of cardiovascular death of the MACD index. Correlations of MACD but not the AC24 with glucose levels at baseline suggest that hyperglycemia may contribute to unique patterns of calcification indicated by the MACD.

    Full Text Available Abstract Background Gardner's syndrome can occasionally be complicated with intra-abdominal desmoid tumor. These tumors usually remain asymptomatic but can exhibit symptoms due to intestinal, vascular and ureteral compression and obstruction. Case presentation A rare case of a 41-year-old male patient with Gardner's syndrome complicated with intra-abdominal desmoid tumor, which first presented as acute abdomen, is presented. Conclusion Extra-abdominal manifestations of Gardner's syndrome along with a palpable abdominal mass would raise suspicion for the presence of a desmoid tumor in the majority of cases. In life-threatening cases, surgical treatment should be considered as a palliative approach, though the extent of excision remains debatable

    1985-05-01

    In aortic insufficiency (AI) the inhibition of the stimulated Renin-Angiotensin-System (RAS) by Captopril (C) reduced afterload and leads consequently to a diminished regurgitation fraction (RF). In 17 patients (pts) with pure severe AI RF, left ventricular ejection fraction (LVEFE) and heart rate were determined before (1) and 1 hr after (2) administration of 25 mg of C.Long term dosis was 3 x 25 mg of C and follow up time was 3-11 months (medium:6). The values were determined by gated radionuclide ventriculography using red blood cells labeled in vivo with 15 mCi Tc-99mROI's were selected over both ventricles in enddiastolic and endsystolic frames. Ventricular boundaries were defined by a fourier phase image overlay. RF was calculated by the background corrected count rate ratio of left and right ventricular ROI. Systolic and diastolic blood pressure (BPs,BPd), plasma levels of angiotensin I,II(A1,A2) and the activity of angiotensin converting enzyme (ACE) were determined before and 1 hr after C administration. After C there is a decrease in RF which persists in the long term follow period in up to to now 8 pts. The authors conclude: inhibition of ACE reduces significantly aortic regurgitation in patients with AI and has thus a beneficial effect on left ventricular performance. This effect persists in long term treatment and therefore seems beneficial to delay the point of operation.

    Kounis syndrome refers to the concurrence of acute coronary events and allergic or hypersensitivity reactions. In this report, we describe the case of a male patient, in whom acute ST-segment elevation and myocardial infarction developed immediately after injection of depot penicillin, and we discuss the Kounis syndrome. A 52-year-old male patient had chest pain, hypotension and ST-elevation on leads DI and aVL of electrocardiography 30 minutes after intramuscular penicillin injection due to cryptic tonsillitis. Kounis syndrome was considered as a possible diagnosis according to the presentation. Histamine and tryptase levels were not studied due to the delay on arrival to the emergency department. The patient promptly underwent coronary angiography, which revealed only diffuse plaques in all main coronary arteries without any obstructive lesion. We found only increased immunoglobulin (Ig) E, which is associated with the syndrome. With this report, we remind clinicians to consider Kounis syndrome in patients who are subjected to allergenic substances and demonstrate acute chest pain.

    Post poliomyelitis syndrome (PPS) is a rare sequel of acute poliomyelitis, usually seen 30-40 years after an acute episode. It is characterized by new muscle weakness seen in survivors of acute poliomyelitis. We describe a rare case of a 50 year old man; with a previous history of poliomyelitis in right lower limb who now presented with complaints of progressive left lower limb weakness for past two years. The diagnosis was made on the basis of clinical suspicion and EMG findings. PPS is not a well recognized disease in Pakistan and due to the lack of documentation; its true prevalence is not known. Though, over the years, cases of Poliomyelitis have decreased worldwide, however, PPS still remains a constant challenge for the physicians. This report highlights the impact of the disease on the quality of life of patients suffering from PPS and emphasis on the need for new therapeutic approach.

Case Report: A 44-year-old female patient presented to us with acute abdominal pain associated with recurrent vomiting and giddiness. On examination, her blood pressure was 80/50 mm Hg. Systemic examination was normal. Further evaluation revealed hypocortisolemia with elevated plasma adrenocorticotropin hormone indicative of primary adrenal insufficiency. Her abdominal computed tomography scan showed features of evolving bilateral adrenal infarction. Etiological work-up revealed prolonged activated thromboplastin time, which didn′t correct with normal plasma, her anti-cardiolipin antibody and lupus anticoagulant were also positive. She was diagnosed to have APS with adrenal insufficiency and she was started on intravenous steroids and heparin infusion. Conclusion: AAI due to the APS can present with acute abdominal pain followed by hypotension. A high index of suspicion is needed to make the correct diagnosis and to initiate appropriate treatment.

    Full Text Available Harm Wienbergen, Uwe ZeymerHerzzentrum Ludwigshafen, Medizinische Klinik B, GermanyAbstract: Fondaparinux is the first selective inhibitor of the coagulation factor Xa which is commercially avaliable for clinical use. It has been approved for the prevention of venous thromboembolism in patients undergoing orthopedic surgery and for the initial therapy of venous thromboembolism. In randomized clinical trials the value of fondaparinux in the treatment of ST-elevation myocardial infarction (STEMI has been investigated. The PENTALYSE study showed that fondaparinux was at least as effective and safe as unfractionated heparin in 333 patients with STEMI undergoing fibrinolysis with t-PA. In the recent large OASIS-6 trial with 12,092 patients the treatment with 2.5 mg fondaparinux daily significantly reduced death and reinfarctions until day 30 compared with guideline recommended usual care and compared with unfractionated heparin (9.7% vs 11.2%, p = 0.008 without increasing major bleedings (1.0% vs 1.3%, p = 0.13. This advantage was predominantly seen in the subgroups of patients with fibrinolysis and without early reperfusion therapy. However, in the subgroup of primary percutaneous coronary interventions (PCIs no clinical benefit of fondaparinux was found, but there were more catheter thrombosis and acute thrombotic complications. In summary, fondaparinux is a new antithrombin that is an efficient, safe, and easy to use in treatment for STEMI patients, particularly those not undergoing primary PCI.Keywords: selective factor Xa inhibition, fondaparinux, acute ST-elevation myocardial infarction, antithrombin therapy

    Full Text Available Background: Acute respiratory distress syndrome (ARDS is one of the most important complications associated with traumatic brain injury (TBI. ARDS is caused by inflammation of the lungs and hypoxic damage with lung physiology abnormalities associated with acute respiratory distress syndrome. Aim of this study is to determine the epidemiology of ARDS and the prevalence of risk factors. Methods: This prospective study performed on patients with acute traumatic head injury hospitalization in the intensive care unit of the Shohaday-e Haftom-e-Tir Hospital (September 2012 to September 2013 done. About 12 months, the data were evaluated. Information including age, sex, education, employment, drug and alcohol addiction, were collected and analyzed. The inclusion criteria were head traumatic patients and exclusion was the patients with chest trauma. Questionnaire was designed with doctors supervision of neurosurgery. Then the collected data were analysis. Results: In this study, the incidence of ARDS was 23.8% and prevalence of metabolic acidosis was 31.4%. Most injury with metabolic acidosis was Subarachnoid hemorrhage (SAH 48 (60% and Subdural hemorrhage (SDH was Next Level with 39 (48% Correlation between Glasgow Coma Scale (GCS and Respiratory Distress Syndrome (ARDS were significantly decreased (P< 0.0001. The level of consciousness in patients with skull fractures significantly lower than those without fractures (P= 0.009 [(2.3±4.6 vs (4.02±7.07]. Prevalence of metabolic acidosis during hospitalization was 80 patients (31.4%. Conclusion: Acute respiratory distress syndrome is a common complication of traumatic brain injury. Management and treatment is essential to reduce the mortality. In this study it was found the age of patients with ARDS was higher than patients without complications. ARDS risk factor for high blood pressure was higher in men. Most victims were pedestrians. The most common injury associated with ARDS was SDH. Our analysis

    Identification and quantification higher risk incidence of aortic rupture or dissection (AARD) could be of clinical interest and improve preventive strategies. Several studies and subsequent meta-analyses have shown chronobiologic variations in the timing of occurrence of myocardial infarction, stroke, and pulmonary embolism. Conversely, such evidences are currently lacking for AARD despite a number of studies available dealing with periodicity. MEDLINE, EMBASE, and Google Scholar databases were searched up to July 2013. Temporal variation in the incidence of AARD was analyzed including all studies analyzing seasonal, monthly, weekly, and circadian aggregations. Two authors independently reviewed and extracted data. Forty-two studies for a total of more than 80 000 patients were included. Our results showed a significantly increased incidence of AARD in Winter (Chi-square 854.92, p < 0.001), with a relative risk (RR) of 1.171 (99% CI 1.169, 1.172), in December (Chi-square 361.03, p < 0.001), RR of 1.142 (99% CI 1.141, 1.143), on Monday (Chi-square 428.09, p < 0.001), RR of 1.214 (99% CI 1.211, 1.216), and in the hours between 6 am and 12 pm (Chi-square 212.02, p < 0.001), RR of 1.585 (99% CI 1.562, 1.609). Subgroup and sensitivity analyses confirmed the results of principal analyses. Our data strongly support the presence of evident rhythmic patterns in the incidence of acute aortic events, characterized by significantly higher risk in Winter, in December, on Monday and between 6 am and 12 pm. Future studies are needed to better clarify the underlying mechanisms and clinical implications.

    Full Text Available Abstract Background Differential diagnosis between acute cardiogenic pulmonary edema (APE and acute lung injury/acute respiratory distress syndrome (ALI/ARDS may often be difficult. We evaluated the ability of chest sonography in the identification of characteristic pleuropulmonary signs useful in the diagnosis of ALI/ARDS and APE. Methods Chest sonography was performed on admission to the intensive care unit in 58 consecutive patients affected by ALI/ARDS or by acute pulmonary edema (APE. Results Ultrasound examination was focalised on finding in the two groups the presence of: 1 alveolar-interstitial syndrome (AIS 2 pleural lines abnormalities 3 absence or reduction of "gliding" sign 4 "spared areas" 5 consolidations 6 pleural effusion 7 "lung pulse". AIS was found in 100% of patients with ALI/ARDS and in 100% of patients with APE (p = ns. Pleural line abnormalities were observed in 100% of patients with ALI/ARDS and in 25% of patients with APE (p All signs, except the presence of AIS, presented a statistically significant difference in presentation between the two syndromes resulting specific for the ultrasonographic characterization of ALI/ARDS. Conclusion Pleuroparenchimal patterns in ALI/ARDS do find a characterization through ultrasonographic lung scan. In the critically ill the ultrasound demonstration of a dyshomogeneous AIS with spared areas, pleural line modifications and lung consolidations is strongly predictive, in an early phase, of non-cardiogenic pulmonary edema.

    Lung morphology in ARDS reflects the rapid evolution from interstitial and alveolar edema to end-stage fibrosis consequent to injury of the alveolocapillary unit. This morphologic progression, termed diffuse alveolar damage, has been subdivided into sequentially occurring exudative, proliferative, and fibrotic phases. Pulmonary lesions correlate with the phase of alveolar damage rather than its specific cause. The pathologic features are consistent with the effects of a host of injurious stimuli and the complex interaction of inflammatory mediators on alveolar epithelial and capillary endothelial cells. Although ARDS frequently culminates in "interstitial" fibrosis, the organization of intraluminal exudate dominates the histologic picture in the proliferative phase and establishes the framework for subsequent fibrous remodeling of the lung. Involvement of the pulmonary vasculature is an important aspect of ARDS, from the initial phase of edema to the terminal stage of intractable pulmonary hypertension. Vascular lesions include thrombotic, fibroproliferative, and obliterative changes that, like the parenchymal lesions, correlate with the temporal phase of DAD. Although ARDS is characterized by extensive bilateral lung involvement, alveolar damage can also affect the lung in a localized fashion. RAD is associated with the same clinical risk factors as DAD, suggesting that there is a spectrum in the extent of lung involvement and disease severity in patients at risk for ARDS. The factors that govern which patients will develop the fulminant syndrome are poorly understood. It must be re-emphasized that the lung is stereotyped in its response to injury and, consequently, descriptive, or even quantitative, studies of lung morphology can only provide clues regarding the initiating factors and pathogenetic mechanisms of ARDS. Progress in understanding the pathogenesis of ARDS and development of rational approaches to therapy will ultimately depend on careful clinical and

    Bloom syndrome (BS) is an inherited genomic instability disorder caused by disruption of the BLM helicase and confers an extreme cancer predisposition. Here we report on a girl with BS who developed acute lymphoblastic leukaemia (ALL) at age nine, and treatment-related acute myeloid leukaemia (t-AML) aged 12. She was compound heterozygous for the novel BLM frameshift deletion c.1624delG and the previously described c.3415C>T nonsense mutation. Two haematological malignancies in a child with BS imply a fundamental role for BLM for normal haematopoiesis, in particular in the presence of genotoxic stress.

    Patients who are diagnosed with acute lung injury/acute respiratory distress syndrome (ALI/ARDS) usually have ventilation-perfusion mismatch, severe decrease in lung capacity, and gas exchange abnormalities. Health care work-ers have implemented various strategies in an attempt to compensate for these pathological alterations. By rotating patients with ALI/ARDS between the supine and prone position, it is possible to achieve a significant improvement in PaO2/FiO2, decrease shunting and therefore improve oxy-genation without use of expensive, invasive and experimen-tal procedures.

    The novel Middle east respiratory syndrome coronavirus (MeRS-CoV) has been identified as a cause of pneumonia; however, it has not been reported as a cause of acute myocarditis. A 60-year-old man presented with pneumonia and congestive heart failure. On the first day of admission, he was found to have an elevated troponin-l level and severe global left ventricular systolic dysfunction on echo-cardiography. The serum creatinine level was found mildly elevated. Chest radiography revealed in the lower lung fields accentuated bronchovascular lung markings and multiple small patchy opacities. Laboratory tests were negative for viruses known to cause myocarditis. Sputum sample was positive for MeRS-CoV. Cardiovascular magnetic resonance revealed evidence of acute myocarditis. the patient had all criteria specified by the international Consensus Group on CMR in Myocarditis that make a clinical suspicion for acute myocarditis. this was the first case that demonstrated that MeRS-CoV may cause acute myocarditis and acute-onset heart failure.

    Full Text Available Abstract Background Apical ballooning syndrome (or Takotsubo cardiomyopathy is a syndrome of transient left ventricular apical ballooning. Although first described in Japanese patients, it is now well reported in the Caucasian population. The syndrome mimicks an acute myocardial infarction but is characterised by the absence of obstructive coronary disease. We describe a serious and poorly understood complication of Takotsubo cardiomyopathy. Case Presentation We present the case of a 65 year-old lady referred to us from a rural hospital where she was treated with thrombolytic therapy for a presumed acute anterior myocardial infarction. Four hours after thrombolysis she developed acute pulmonary oedema and a new systolic murmur. It was presumed she had acute mitral regurgitation secondary to a ruptured papillary muscle, ischaemic dysfunction or an acute ventricular septal defect. Echocardiogram revealed severe mitral regurgitation, left ventricular apical ballooning, and systolic anterior motion of the mitral valve with significant left ventricular outflow tract gradient (60–70 mmHg. Coronary angiography revealed no obstructive coronary lesions. She had an intra-aortic balloon pump inserted with no improvement in her parlous haemodynamic state. We elected to replace her mitral valve to correct the outflow tract gradient and mitral regurgitation. Intra-operatively the mitral valve was mildly myxomatous but there were no structural abnormalities. She had a mechanical mitral valve replacement with a 29 mm St Jude valve. Post-operatively, her left ventricular outflow obstruction resolved and ventricular function returned to normal over the subsequent 10 days. She recovered well. Conclusion This case represents a serious and poorly understood association of Takotsubo cardiomyopathy with acute pulmonary oedema, severe mitral regurgitaton and systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction.

    Patients with Marfan syndrome require repeated imaging for monitoring of aortic root aneurysms. Therefore, we evaluated the agreement and reproducibility of cine-MRI and echocardiography measurements of the sinuses of Valsalva in patients with suspected Marfan syndrome. 51 consecutive patients with suspected Marfan syndrome were prospectively examined using cine-MRI and echocardiography. Two readers independently measured aortic root diameters at the level of the sinuses of Valsalva in both cine-MRI and echocardiography. Statistics included intraclass correlation coefficient, Pearson correlation coefficient, Bland-Altman analysis, and two-sided t-test. In 38 of the 51 individuals (74.5 %), the diagnosis of Marfan syndrome was established according to the criteria of the Ghent-2 nosology. Cine-MRI measurements of the sinuses of Valsalva revealed a strong correlation with echocardiography (r=0.929), but a statistically significant bias of -1.0 mm (p<0.001). The mean absolute diameter for sinuses of Valsalva obtained by cine-MRI was 32.3 ± 5.8 mm as compared to 33.4 ± 5.4 mm obtained by echocardiography. Interobserver agreement of measurements of the sinuses of Valsalva was higher for cine-MRI than for echocardiography (p=0.029). Despite small, but statistically significant differences in terms of agreement and reproducibility, cine-MRI and echocardiographic measurements of aortic root diameters provide comparable results without a significant clinical difference. Therefore both techniques may be used for monitoring of the aortic root in patients with Marfan syndrome.

    2015-12-01

    The feasibility and safety of transradial coronary intervention was demonstrated soon after the description of the transfemoral approach, despite which the use of the femoral artery still dominates in acute coronary syndrome intervention. The advantages of using the radial artery are virtual elimination of access site complications and an important reduction in bleeding, both of which are of utmost importance to the patient with myocardial infarction. Randomised controlled trials have now documented what seems inherent; that transradial intervention should bring with it an advantage in terms of morbidity and mortality in this cohort. The potential disadvantages in terms of speed of procedure and radiation exposure are negated by operator experience. Registries have illustrated that conversion on a large scale from the femoral to the transradial approach is safe and saves lives, most convincingly so in acute coronary syndrome intervention. This review discusses the potential benefits and risks of the alternative access sites in acute patients and explores how these are borne out in the published data.

    2017-02-22

    Ivabradine is a heart rate reducing agent that exhibits anti-ischemic effects through the inhibition of funny electrical current in the sinus node resulting in heart rate reduction, thus enabling longer diastolic perfusion time, and reduced myocardial oxygen consumption without detrimental changes in arterial blood pressure, coronary vasomotion, and ventricular contractility. The current guideline-based clinical use of Ivabradine is reserved for patients with stable angina pectoris who cannot tolerate or whose symptoms are inadequately controlled with beta blockers. In patients with chronic heart failure and reduced ejection fraction, Ivabradine has demonstrated beneficial effects in improving clinical outcomes when added to conventional therapy. However, the role of Ivabradine in acute coronary syndromes has not been established. Based on the results from some relevant preclinical studies and a limited amount of clinical data that were reported recently, the role of Ivabradine in acute ischemic events warrants further investigation. The aim of this review is to provide an overview of the available literature on the potential role of Ivabradine in the clinical context of acute coronary syndromes.

    La prévalence des maladies cardiovasculaires connaît une croissance rapide dans les pays en développement, entraînant une incidence croissante du syndrome coronarien aigu (SCA. Les modalités de diagnostic et de traitement de cette maladie continuent d’évoluer, et il convient de tenir compte des ressources locales lors de la réalisation d’un diagnostic et la détermination des options thérapeutiques. Cet article constitue un guide à la prise en charge du SCA fondé sur l’expérience, et fournit des recommandations spécifiques destinées aux médecins hospitaliers travaillant dans les pays à bas et moyen revenu. Le diagnostic du SCA, y compris les SCA sans élévation du ST et avec élévation du ST, se concentre sur la stratification du risque, la vigilance relative aux manifestations subtiles ou atypiques, et la prise en considération d’autres causes des douleurs poitrinaires. Le processus de diagnostic implique l’évaluation des facteurs de risque, la connaissance des antécédents médicaux défavorables et les conclusions de l’examen physique (des variantes étant susceptibles d’exister dans les différentes populations, ainsi que l’utilisation de tests de diagnostic appropriés.

    Acute gastric dilation is a rare but recognised complication in patients with bulimia and anorexia following binge episodes owing to decreased bowel motility. We present a rare case of acute gastric dilation secondary to bulimia in an otherwise healthy 18-year-old female patient that resulted in compression and complete occlusion of the abdominal aorta, leading to acute mesenteric and bilateral lower limb ischaemia. This resolved immediately following a laparotomy and gastric decompression. Management of these patients is very challenging owing to the lack of a successful precedent. To our knowledge, such a catastrophic complication has only ever been reported once in the literature and the outcome was fatal. Our case is of additional importance as it offers a successful management strategy for these patients.

    Objective Acute kidney injury (AKI) frequently occurs after catheter-based interventional procedures and increases mortality. How-ever, the implications of AKI before thoracic endovascular aneurysm repair (TEVAR) of type B acute aortic dissection (AAD) remain un-clear. This study evaluated the incidence, predictors, and in-hospital outcomes of AKI before TEVAR in patients with type B AAD. Meth-ods Between 2009 and 2013, 76 patients were retrospectively evaluated who received TEVAR for type B AAD within 36 h from symptom onset. The patients were classified into no-AKI vs. AKI groups, and the severity of AKI was further staged according to kidney disease:im-proving global outcomes criteria before TEVAR. Results The incidence of preoperative AKI was 36.8%. In-hospital complications was significantly higher in patients with preoperative AKI compared with no-AKI (50.0%vs. 4.2%, respectively;P<0.001), including acute renal failure (21.4%vs. 0, respectively;P<0.001), and they increased with severity of AKI (P<0.001). The maximum levels of body tem-perature and white blood cell count were significantly related to maximum serum creatinine level before TEVAR. Multivariate analysis showed that systolic blood pressure on admission (OR:1.023;95%CI:1.003–1.044;P=0.0238) and bilateral renal artery involvement (OR:19.076;95%CI:1.914–190.164;P=0.0120) were strong predictors of preoperative AKI. Conclusions Preoperative AKI frequently oc-curred in patients with type B AAD, and correlated with higher in-hospital complications and enhanced inflammatory reaction. Systolic blood pressure on admission and bilateral renal artery involvement were major risk factors for AKI before TEVAR.

    Full Text Available Ventricular septal defect ( VSD with prolapse of the right coronary cusp and aortic regurgitation can be managed surgically with the anatomical correction technique . However when the VSD is located underneath the non coronary cusp surgical management differs due to anatomical constraints and secondary pathological changes seen in the non coronary cusp. It is therefore important that the location of the VSD and the morphology of prolapsing cusp be characterised preoperatively in order to plan appropriate surgical repair. We present a case study in which we discuss the salient differences in the surgical management of the prolapsing right and the prolapsing non coronary cusps.

    Identification of individuals who are at risk of suffering from acute coronary syndromes (ACS) may allow to introduce preventative measures. We aimed to identify ACS-related urinary peptides, that combined as a pattern can be used as prognostic biomarker. Proteomic data of 252 individuals enrolled in four prospective studies from Australia, Europe and North America were analyzed. 126 of these had suffered from ACS within a period of up to 5 years post urine sampling (cases). Proteomic analysis of 84 cases and 84 matched controls resulted in the discovery of 75 ACS-related urinary peptides. Combining these to a peptide pattern, we established a prognostic biomarker named Acute Coronary Syndrome Predictor 75 (ACSP75). ACSP75 demonstrated reasonable prognostic discrimination (c-statistic = 0.664), which was similar to Framingham risk scoring (c-statistics = 0.644) in a validation cohort of 42 cases and 42 controls. However, generating by a composite algorithm named Acute Coronary Syndrome Composite Predictor (ACSCP), combining the biomarker pattern ACSP75 with the previously established urinary proteomic biomarker CAD238 characterizing coronary artery disease as the underlying aetiology, and age as a risk factor, further improved discrimination (c-statistic = 0.751) resulting in an added prognostic value over Framingham risk scoring expressed by an integrated discrimination improvement of 0.273 ± 0.048 (P < 0.0001) and net reclassification improvement of 0.405 ± 0.113 (P = 0.0007). In conclusion, we demonstrate that urinary peptide biomarkers have the potential to predict future ACS events in asymptomatic patients. Further large scale studies are warranted to determine the role of urinary biomarkers in clinical practice. PMID:28273075

    2014-03-01

    Heart failure is a complex syndrome that affects almost all organs and systems of the body. Signs and symptoms of organ dysfunction, in particular kidney dysfunction, may be accentuated or become evident for the first time during acute decompensation of heart failure. Cardiorenal syndrome has been defined as the simultaneous dysfunction of both the heart and the kidney, regardless of which of the two organs may have suffered the initial damage and regardless also of their previous functional status. Research into the mechanisms regulating the complex relationship between the two organs is prompting the search for new biomarkers to help physicians detect renal damage in subclinical stages. Hence, a preventive approach to renal dysfunction may be adopted in the clinical setting in the near future. This article provides a general overview of cardiorenal syndrome and an update of the physiopathological mechanisms involved. Special emphasis is placed on the role of visceral congestion as an emergent mechanism in this syndrome. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    Full Text Available AbstractObjectives: Regardless of diabetes status, hyperglycemia on arrival for patients presenting with acute coronary syndrome, has been associated with adverse outcomes including death. The aim of this study is to look at the frequency and prognostic significance of acute phase hyperglycemia among patients attending the coronary care unit with acute coronary syndrome over the in-hospital admission days.Methods: The study included 287 consecutive patients in the Al- Faiha Hospital in Basrah (Southern Iraq during a one year period from December 2007 to November 2008. Patients were divided into two groups with respect to admission plasma glucose level regardless of their diabetes status (those with admission plasma glucose of <140 mg/dl (7.8 mmol/L and those equal to or more than that. Acute phase hyperglycemia was defined as a non-fasting glucose level equal to or above 140 mg/dl (7.8 mmol/L regardless of past history of diabetes.Results: Sixty one point seven percent (177 of patients were admitted with plasma glucose of ≥140 mg/dl (7.8 mmol/L. There were no differences were found between both groups regarding the mean age, qualification, and smoking status, but males were predominant in both groups. A family history of diabetes, and hypertension, were more frequent in patients with plasma glucose of ≥140 mg/dl (7.8 mmol/L. There were no differences between the two groups regarding past history of ischemic heart disease, stroke, lipid profile, troponin-I levels or type of acute coronary syndrome. Again heart failure was more common in the admission acute phase hyperglycemia group, but there was no difference regarding arrhythmia, stroke, or death. Using logistic regression with heart failure as the dependent variable we found that only the admission acute phase hyperglycemia (OR=2.1344, 95�0CI=1.0282-4.4307; p=0.0419 was independently associated with heart failure. While male gender, family history of diabetes mellitus, hypertension and

    Current perspectives for management of acute respiratory insufficiency in premature infants with acute respiratory syndrome and the pathology of acute respiratory insufficiency in the preterm infant, including the current therapy modalities on disposition are presented. Since the therapeutical challenge and primary clinical goal are to normalize ventilation ratio and lung perfusion, when respiratory insufficiency occurs, it is very important to introduce the respiratory support as soon possible, in order to reduce development of pulmonary cyanosis and edema, and intrapulmonary or intracardial shunts. A characteristic respiratory instability that reflects through fluctuations in gas exchange and ventilation is often present in premature infants. Adapting the respiratory support on a continuous basis to the infant's needs is challenging and not always effective. Although a large number of ventilation strategies for the neonate are available, there is a need for additional consensus on management of acute respiratory distress syndrome in pediatric population lately redefined by Berlin definition criteria, in order to efficiently apply various modes of respiratory support in daily pediatrician clinical use.

    Objective To study whether myeloperoxidase (MPO) can provide prognostic information in patients with acute coronary syndromes (ACS). Methods The study population consisted of 274 consecutive patients with ACS. All patients underwent coronary angiography which showed significant coronary artery disease and blood samples were collected at admission. Follow-ups were scheduled at 1, 3, and 6 months.The end point included cardiac death, acute myocardial infarction (MI), percutaneous or surgical revascularization. Results Patients with elevated MPO serum levels (MPO ≥ 72.2 AUU/L) were more likely to have diabetics and had a history of coronary events. Kaplan-Meier event rate curves with accumulative incidence of end point at 6-month follow-up in the MPO ≥ 72.2 AUU/L group was significantly higher than in MPO<72.2 AUU/L group. Conclusions MPO may be a powerful predictor of adverse outcome in patients with ACS.

    Full Text Available We present the case of a young man who was transferred to our hospital with worsening acute disseminated encephalomyelitis (ADEM despite treatment with intravenous methylprednisolone, intravenous immunoglobulin and plasma exchange. He developed neuroleptic malignant syndrome (NMS without the use of dopamine-modulating drugs. His progressive clinical improvement started after treatment with intravenous cyclophosphamide and methylprednisolone. In our patient, acute demyelination with severe bilateral inflammation of the basal ganglia could have caused a state of central dopamine depletion, creating proper conditions for the development of NMS. Significant clinical improvement of our case after treatment with intravenous cyclophosphamide and steroids provides further evidence for a possible role of the inflammatory lesions in the pathogenesis of NMS in association with ADEM.

    Acute Respiratory Distress Syndrome (ARDS) is due to many causes. The absence of a universal definition up until now has led to a series of practical problems for a definitive diagnosis. The incidences of ARDS and Acute Lung Injury (ALI) vary widely in the current literature. The American-European Consensus Conference definition has been applied since its publication in 1994 and has helped to improve knowledge about ARDS. However, 18 years later, in 2011, the European Intensive Medicine Society, requested a team of international experts to meet in Berlin to review the ARDS definition. The purpose of the Berlin definition is not to use it as a prognostic tool, but to improve coherence between research and clinical practice.

    Despite a number of clinical trials there is still controversy about the role of corticosteroid therapy in acute respiratory distress syndrome (ARDS). In addition recent meta-analyses differed markedly in the conclusions. This review is intended to provide a short practical guide for the clinician. Based on the available literature, high-dose and pre-emptive administration of corticosteroids is hazardous and not indicated. A low-dose corticosteroid regime given for 4 weeks may potentially be helpful and can be considered in acute or unresolved ARDS in less than 14 days after onset of ARDS, if a close infection surveillance program is available, if neuromuscular blockade can be avoided and if a stepwise dose reduction of corticosteroids is performed. The total daily dose at the beginning of treatment should not exceed 2 mg/kg body weight (BW) methylprednisolone.

    Severe acute respiratory syndrome (SARS) is a serious disease with many puzzling features. We present a simple, dynamic model to assess the epidemic potential of SARS and the effectiveness of control measures. With this model, we analysed the SARS epidemic data in Beijing. The data fitting gives the basic case reproduction number of 2.16 leading to the outbreak, and the variation of the effective reproduction number reflecting the control effect. Noticeably, our study shows that the response time and the strength of control measures have significant effects on the scale of the outbreak and the lasting time of the epidemic.

    In the absence of obvious trauma, diagnosis of acute compartment syndrome (ACS) of the thigh can easily be delayed, as disproportional pain is not always present. We present a case of ACS of the anterior right thigh compartment in a healthy, semiprofessional rugby player with normal coagulation, who sustained a seemingly innocuous blow during a rugby match. Following early surgical fasciotomy, he returned to his preinjury playing standards within 12 months. Our literature review suggests that high muscle mass, young, athletic males participating in a contact sport are mostly at risk of developing ACS of the thigh. PMID:26250368

    Almost all orthopaedic surgeons come across acute compartment syndrome (ACS) in their clinical practice. Diagnosis of ACS mostly relies on clinical findings. If the diagnosis is missed and left untreated, it can lead to serious consequences which can endanger limb and life of the patient and also risk the clinician to face lawsuits. This review article highlights the characteristic features of ACS which will help an orthopaedic surgeon to understand the pathophysiology, natural history, high risk patients, diagnosis, and surgical management of the condition.

    Increased cardiac troponin concentrations in acute coronary syndrome (ACS) identify patients with ongoing cardiomyocyte necrosis who are at increased risk. However, with the use of more precise assays, cardiac troponin increases are commonly noted in other cardiovascular conditions as well. This has generated interest in the use of cardiac troponin for prognostic assessment and clinical management of these patients. In this review, we have summarized the data from studies investigating the implications of cardiac troponin concentrations in various acute and chronic conditions beyond ACS, i.e., heart failure, myocarditis, Takotsubo cardiomyopathy, aortic dissection, supraventricular arrhythmias, valve disease, pulmonary arterial hypertension, stroke, and in the perioperative setting. Cardiac troponin concentrations are often detectable and frankly increased in non-ACS conditions, in particular when measured with high-sensitivity (hs) assays. With the exception of myocarditis and Takotsubo cardiomyopathy, cardiac troponin concentrations carry strong prognostic information, mainly with respect to mortality, or incipient and/or worsening heart failure. Studies investigating the prognostic benefit associated with cardiac troponin-guided treatments however, are almost lacking and the potential role of cardiac troponin in the management of non-ACS conditions is not defined. Increased cardiac troponin indicates increased risk for adverse outcome in patients with various cardiovascular conditions beyond ACS. Routine measurement of cardiac troponin concentrations can however, not be generally recommended unless there is a suspicion of ACS. Nonetheless, any finding of an increased cardiac troponin concentration in a patient without ACS should at least prompt the search for possible underlying conditions and these should be managed meticulously according to current guidelines to improve outcome. © 2016 American Association for Clinical Chemistry.

    Although both Acute Kidney Injury Network (AKIN) and risk, injury, failure, loss, and end-stage (RIFLE) kidney disease criteria are frequently used to diagnose acute kidney injury (AKI), they have rarely been compared in the diagnosis of AKI in patients undergoing surgery for infrarenal abdominal aortic aneurysm (AAA). This study investigated the incidence of, and risk factors for, AKI, defined by AKIN and RIFLE criteria, and compared their ability to predict mortality after infrarenal AAA surgery. This study examined 444 patients who underwent infrarenal AAA surgery between January 1999 and December 2011. Risk factors for AKI were assessed by multivariable analyses, and the impact of AKI on overall mortality was assessed by a Cox's proportional hazard model with inverse probability of treatment weighting (IPTW). Net reclassification improvement (NRI) was used to assess the performance of AKIN and RIFLE criteria in predicting overall mortality. AKI based on AKIN and RIFLE criteria occurred in 82 (18.5%) and 55 (12.4%) patients, respectively. The independent risk factors for AKI were intraoperative red blood cell (RBC) transfusion and chronic kidney disease (CKD) by AKIN criteria, and age, intraoperative RBC transfusion, preoperative atrial fibrillation, and CKD by RIFLE criteria. After IPTW adjustment, AKI was related to 30 day mortality and overall mortality. NRI was 15.2% greater (P=0.04) for AKIN than for RIFLE criteria in assessing the risk of overall mortality. Although AKI defined by either AKIN or RIFLE criteria was associated with overall mortality, AKIN criteria showed better prediction of mortality in patients undergoing infrarenal AAA surgery. © The Author 2014.

    Background A few recent studies have reported that inflammation is associated with the prognosis of acute aortic dissection (AD).There is,however,no systemic investigation regarding the role of plasma C-reactive protein (CRP) and white blood cell (WBC) levels in predicting in-hospital clinical events of acute type AAD.Methods The levels of high-sensitivity CRP and WBC counts were systemically determined after admission in 36 patients with acute type A AD.The variations of plasma CRP and WBC levels in different time windows (admission,1,2,3,4,6,8 days) in patients with acute type A AD were analyzed between patients with events and without events.Results During hospitalization,five patients died,and increased levels of CRP and WBC were found in patients died with acute type A AD compared with patients survived (P <0.01,respectively).Medical treatment may significantly decrease inflammatory response in survived patients with acute type A AD.Additionally,patients with complication of pleural effusion showed higher CRP and WBC levels (P=0.046,P=0.018,respectively).Lower WBC levels were found in survived patients treated medically (P=0.001).Moreover,mean CRP and WBC levels had positive correlations with aortic diameter (r=0.364,P=0.000;r=0.333,P=0.000,respectively) and age (r=0.270,P=0.000,respectively),while negative correlations with the time from onset of symptoms to hospital admission (r=-0.229,P=0.000,r=-0.200,P=0.002,respectively).Univariate analysis showed that age ≥65 years,CRP ≥12.05 mg/L,WBC ≥12.16×109/L,aortic diameter ≥48mm,pleural effusion and diastolic blood pressure ≥105 mmHg were associated with hospital mortality.While CRP ≥12.05 mg/L,WBC ≥12.16×109/L,aortic diameter ≥48 mm were strongly associated with hospital mortality in multiple Logistic regression analysis.Conclusions The results suggested that CRP and WBC were preferred markers for predicting the clinical events in patients with acute type A AD,especially death during

    Full Text Available Background: Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS. Objective: To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Methods: Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged <65 years, hospitalized with diagnosis of ACS. The Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI, which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE, emotional distancing (EmD, dehumanization (De and professional fulfillment (PF. The Lipp’s Stress Symptoms Inventory for Adults (LSSI was applied to evaluate global stress. Results: Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. Conclusion: We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    Objective: To explore the relationship of Traditional Chinese Medicine (TCM) Syndrome type and coronary arteriography (CAG) with respect to the number and degree of stenosed branches of coronary artery (CA) and ACC/AHA stage of acute coronary syndrome (ACS), to provide an objective evidence for TCM Syndrome typing on ACS.Methods: Ninety patients of ACS with their TCM Syndrome typing and CAG successfully conducted were enrolled in this study. They were classified into 3 Syndrome types, the blood stasis type (typeⅠ), the phlegm stagnant with blood stasis type (typeⅡ), and the endogenous collateral Wind type (typeⅢ). The scores of the number and severity of the stenosis branch of CA and ACC/AHA lesion stage in different Syndrome types were calculated respectively and analysed statistically by Ridit analysis.Results: The number of stenosed branches increased gradually with the Syndrome type changing from Ⅰ→Ⅱ→Ⅲ, compared the type Ⅲ with the other two types(P<0.01). The severity of stenosis in typeⅠ and Ⅱ were similar, but that of Type Ⅲ, much aggravated was significantly different from that in the former two (P<0.01). The ACC/AHA stage of coronary lesion tended to be more complex as the Syndrome type changed, patients of TCM typeⅠ and Ⅱ had mostly lesion of stage A or B1 , while lesion in majority of patients of type Ⅲ belonged to stage B2 or C, comparison between the three types showed significant difference (P<0.01). Conclusion: Most ACS patients of TCM Syndrome type Ⅲ with tri-branch, severe stenosed coronary arteries, belong to the complex ACC/AHA stage of B2 and C.

    Guillain-Barre syndrome (GBS) is the most common cause of acute flaccid paralysis worldwide both in adult and pediatric population. Although flaccid paralysis is the hallmark of this disease, there are some rare variants which may be easily missed unless suspected. Here, we present a very rare variant of GBS - acute bulbar palsy plus syndrome in a pediatric patient. A 13-year-old female child presented with right-sided lower motor neuron type of facial palsy and palsy of bilateral glossopharyngeal and vagus nerve of 2 weeks duration. On detailed neurological examination, motor and sensory system were normal, but the deep tendon reflexes were absent universally. Nerve conduction study showed demyelinating motor neuropathy. Based on typical clinical course and electrophysiological studies, the diagnosis was made. To the best of our knowledge, this is the first pediatric case of unilateral facial palsy with bulbar involvement without any motor abnormality.

    Drug-induced type I hypersensitivity reactions are frequent. Sometimes, acute coronary syndrome (ACS) can be registered in such patients, which may have a serious impact on the course and management of the allergic reaction. Because of potentially atypical ACS clinical presentations, the ECG is an obligatory diagnostic tool in any allergic reaction. Coronary artery spasm is the pathophysiological basis of ACS, triggered by the action of potent vasoactive mediators (histamine, neutral protease...

    Background Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). Objective To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Methods Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged dehumanization (De) and professional fulfillment (PF). The Lipp’s Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Results Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. Conclusion We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital. PMID:25517388

    Levels of testosterone and estradiol influence the incidence of cardiovascular diseases: generally, estrogens in females are protective before menopause; coronaropathies, hypertension, and dyslipidemias in normal men are more frequent at comparable ages. We investigated the modulation by castration of in vitro vasoreactivity, serum lipid content, and systolic blood pressure (SBP) in rats with sucrose-induced metabolic syndrome. The main characteristics of the rat model are: hypertriglyceridemia, moderately high blood pressure, intra-abdominal accumulation of adipose tissue, hyperinsulinemia, nephropathy, increased oxidative stress, and altered vasoreactivity. Male weanling rats received 30% sucrose solution for 16 weeks (metabolic syndrome; MS), controls (C) had plain water; both had commercial rodent chow. They were subdivided into five groups with two subgroups each: Group 1, intact C and MS rats, Groups 2-5, C and MS rats castrated for periods of 16, 12, 8, and 4 weeks. At the end of the study period, systolic blood pressure was measured, and blood and aortas were obtained for fatty acid determination and vasoreactivity assays, respectively. After 16 weeks' sucrose treatment MS aortas showed hypercontractility and decreased vasodilation. Palmitic and palmitoleic acids were increased in MS versus C. Arachidonic acid levels in MS were lower than in intact or castrated C. Long-term castration of 16 weeks normalized the levels of palmitic and oleic acids. With the shorter periods of castration, contractility increased and relaxation decreased in C and MS, but it was more significant in C. Regarding fatty acid composition, long-term castration increased polyunsaturated (arachidonic and eicosapentaenoic) fatty acids. The shorter periods did not modify the fatty acid profile in either C or MS. Metabolic syndrome altered SBP, aortic reactivity, and levels of fatty acids; castration of long duration normalized them in some cases.

    The aim of our study was to document the estimated sensitivity and specificity of continuous intracompartmental pressure monitoring for the diagnosis of acute compartment syndrome. From our prospective trauma database, we identified all patients who had sustained a tibial diaphyseal fracture over a ten-year period. A retrospective analysis of 1184 patients was performed to record and analyze the documented use of continuous intracompartmental pressure monitoring and the use of fasciotomy. A diagnosis of acute compartment syndrome was made if there was escape of muscles at fasciotomy and/or color change in the muscles or muscle necrosis intraoperatively. A diagnosis of acute compartment syndrome was considered incorrect if it was possible to close the fasciotomy wounds primarily at forty-eight hours. The absence of acute compartment syndrome was confirmed by the absence of neurological abnormality or contracture at the time of the latest follow-up. Of 979 monitored patients identified, 850 fit the inclusion criteria with a mean age of thirty-eight years (range, twelve to ninety-four years), and 598 (70.4%) were male (p compartment syndrome: 141 had acute compartment syndrome (true positives), six did not have it (false positives), and five underwent fasciotomy despite having a normal differential pressure reading, with subsequent operative findings consistent with acute compartment syndrome (false negatives). Of the 698 patients (82.1%) who did not undergo fasciotomy, 689 had no evidence of any late sequelae of acute compartment syndrome (true negatives) at a mean follow-up time of fifty-nine weeks. The estimated sensitivity of intracompartmental pressure monitoring for suspected acute compartment syndrome was 94%, with an estimated specificity of 98%, an estimated positive predictive value of 93%, and an estimated negative predictive value of 99%. The estimated sensitivity and specificity of continuous intracompartmental pressure monitoring for the diagnosis of

    Antisynthetase syndrome has been recognized as an important cause of autoimmune inflammatory myopathy in a subset of patients with polymyositis and dermatomyositis. It is associated with serum antibody to aminoacyl-transfer RNA synthetases and is characterized by a constellation of manifestations, including fever, myositis, interstitial lung disease, mechanic's hand-like cutaneous involvement, Raynaud phenomenon, and polyarthritis. Lung disease is the presenting feature in 50% of the cases. We report a case of a 60-year-old female with acute respiratory distress syndrome (ARDS), which later proved to be an unexpected and initial manifestation of anti-Jo-1 antibody–positive antisynthetase syndrome. The present case showed resolution of ARDS after treatment with high-dose corticosteroids. Given that steroids are not greatly beneficial in the treatment of ARDS, it is likely that the improvement of the respiratory symptoms in this patient also resulted from the prompt suppression of the inflammatory systemic response by corticosteroids.

    Full Text Available Background: Abdominal obesity is an important cardiovascular risk factor. Therefore, identifying the best method for measuring waist circumference (WC is a priority. Objective: To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS as a predictor of cardiovascular complications during hospitalization. Methods: Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1, point of minimum circumference (2; immediately above the iliac crest (3, umbilicus (4, one inch above the umbilicus (5, one centimeter above the umbilicus (6, smallest rib and (7 the point of greatest circumference around the waist (8. Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. Results: A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67% patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. Conclusion: The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes.

    Full Text Available Backgroud: Acute coronary syndrome (ACS is an unstable and dynamic process that includes unstable angina, ST elevation myocardial infarction, and non-ST elevation myocardial infarction. Despite recent technological advances in early diognosis of ACS, differentiating between different types of coronary diseases in the early hours of admission is controversial. The present study was aimed to accurately differentiate between various coronary events, using machine learning techniques. Such methods, as a subset of artificial intelligence, include algorithms that allow computers to learn and play a major role in treatment decisions. Methods: 1902 patients diagnosed with ACS and admitted to hospital were selected according to Euro Heart Survey on ACS. Patients were classified based on decision tree J48. Bagging aggregation algorithms was implemented to increase the efficiency of algorithm. Results: The performance of classifiers was estimated and compared based on their accuracy computed from confusion matrix. The accuracy rates of decision tree and bagging algorithm were calculated to be 91.74% and 92.53%, respectively. Conclusion: The proposed methods used in this study proved to have the ability to identify various ACS. In addition, using matrix of confusion, an acceptable number of subjects with acute coronary syndrome were identified in each class.

    Objective: To investigate the relationship of matrix metalloproteinase-9 polymorphism to acute coronary syndrome and its affect on the severity of coronary artery disease. Methods: By means of polymerase chain reaction (PCR) and restriction fragment length polymorphism, genotypes of 245 patients with acute coronary syndrome(ACS) and 205 healthy subjects were tested. Genotypes displaying C-1562T functional promoter polymorphism (of the MMP-9 gene) were determined. The relationship between the polymorphism of the MMP-9 gene and ACS and the severity of coronary vessels diseased was analyzed. Results: The frequency of C/T plus T/T genotypes and T allele in patients with ACS was significantly higher than that in healthy subjects (22.1% vs 12.7% and 11.4% vs 6.6% respectively). But they were not associated with the number of coronary arteries diseased. Conclusion:The MMP-9 polymorphism may be susceptible to ACS. But there was not significant difference between the AMI and UAP subgroups.

    Spontaneous platelet aggregation was evaluated in patients with acute coronary syndrome on days 1, 3-5, and 8-12 of the disease. On day 1, aggregation was analyzed after aspirin, but before clopidogrel administration; during other periods after both antiaggregants. The mean levels of spontaneous aggregation after antithrombotic therapy did not change during different periods after the onset of acute coronary syndrome, in contrast to ADP-induced aggregation that decreased after the development of clopidogrel effects (days 3-5 and 8-12). Spontaneous aggregation during different periods directly correlated (r>0.4, p<0.01) with spontaneous and ADP-induced aggregation during different periods (r=0.372, r=0.447, and r=0.543 on days 1, 3-5, and 8-12, respectively; p<0.01). No relationship between spontaneous aggregation and plasma concentration of von Willebrand's factor was detected. Spontaneous aggregation was completely suppressed after in vitro addition of prostaglandin E1 (platelet activation inhibitor), slightly (by ≈20%) decreased in the presence of antibodies to glycoprotein Ib, blocking its reactions with von Willebrand's factor, and did not change in the presence of aptamer inhibiting thrombin activity.

    Cardiorenal syndrome has been defined as the simultaneous dysfunction of both the heart and the kidney. Worsening renal function that occurs in patients with acute heart failure has been classified as cardiorenal syndrome type 1. In this setting, worsening renal function is a common finding and is due to complex, multifactorial, and not fully understood processes involving hemodynamic (renal arterial hypoperfusion and renal venous congestion) and nonhemodynamic factors. Traditionally, worsening renal function has been associated with worse outcomes, but recent findings have revealed mixed and heterogeneous results, perhaps suggesting that the same phenotype represents a diversity of pathophysiological and clinical situations. Interpreting the magnitude and chronology of renal changes together with baseline renal function, fluid overload status, and clinical response to therapy might help clinicians to unravel the clinical meaning of renal function changes that occur during an episode of heart failure decompensation. In this article, we critically review the contemporary evidence on the pathophysiology and clinical aspects of worsening renal function in acute heart failure.

    Full Text Available Sheehan′s syndrome occurs as a result of ischemic pituitary necrosis secondary to severe postpartum bleeding. It is one of the most common causes of hypopituitarism, characterized by variable clinical presentation. Acute kidney injury occurs rarely in Sheehan′s syndrome and most of the cases have been found to be precipitated by rhabdomyolysis. We here present a case of Sheehan′s syndrome with acute kidney injury where theprecipitating cause was chronic hypocortisolemia. We believe this is the first reported case of Sheehan′s syndrome in which acute kidney injury was precipitated by adrenal insufficiency.

    Full Text Available Background/Aims. Acute kidney injury is a common problem for patients with cirrhosis and is associated with poor survival. We aimed to examine the association between type of acute kidney injury and 90-day mortality. Methods. Prospective cohort study at a major US liver transplant center. A nephrologist’s review of the urinary sediment was used in conjunction with the 2007 Ascites Club Criteria to stratify acute kidney injury into four groups: prerenal azotemia, hepatorenal syndrome, acute tubular necrosis, or other. Results. 120 participants with cirrhosis and acute kidney injury were analyzed. Ninety-day mortality was 14/40 (35% with prerenal azotemia, 20/35 (57% with hepatorenal syndrome, 21/36 (58% with acute tubular necrosis, and 1/9 (11% with other (p=0.04 overall. Mortality was the same in hepatorenal syndrome compared to acute tubular necrosis (p=0.99. Mortality was lower in prerenal azotemia compared to hepatorenal syndrome (p=0.05 and acute tubular necrosis (p=0.04. Ten participants (22% were reclassified from hepatorenal syndrome to acute tubular necrosis because of granular casts on urinary sediment. Conclusions. Hepatorenal syndrome and acute tubular necrosis result in similar 90-day mortality. Review of urinary sediment may add important diagnostic information to this population. Multicenter studies are needed to validate these findings and better guide management.

    Full Text Available Clinical and basic experimental approaches to pediatric acute lung injury (ALI, including acute respiratory distress syndrome (ARDS, have historically focused on acute care and management of the patient. Additional efforts have focused on the etiology of pediatric ALI and ARDS, clinically defined as diffuse, bilateral diseases of the lung that compromise function leading to severe hypoxemia within seven days of defined insult. Insults can include ancillary events related to prematurity, can follow trauma and/or transfusion, or can present as sequelae of pulmonary infections and cardiovascular disease and/or injury. Pediatric ALI/ARDS remains one of the leading causes of infant and childhood morbidity and mortality, particularly in the developing world. Though incidence is relatively low, ranging from 2.9-9.5 cases/100,000 patients/year, mortality remains high, approaching 35% in some studies. However, this is a significant decrease from the historical mortality rate of over 50%. Several decades of advances in acute management and treatment, as well as better understanding of approaches to ventilation, oxygenation and surfactant regulation, have contributed to improvements in patient recovery. As such, there is a burgeoning interest in the long term impact of pediatric ALI/ARDS. Chronic pulmonary deficiencies in survivors appear to be caused by inappropriate injury repair, with fibrosis and predisposition to emphysema arising as irreversible secondary events that can severely compromise pulmonary development and function, as well as the overall health of the patient. In this chapter, the long term effectiveness of current treatments will be examined, as will the potential efficacy of novel, acute and long term therapies that support repair and delay or even impede the onset of secondary events, including fibrosis.

    Heritable thoracic aortic aneurysms and dissections (TAAD), including Marfan syndrome (MFS), currently lack a cure, and causative mutations have been identified for only a fraction of affected families. Here we identify the metalloproteinase ADAMTS1 and inducible nitric oxide synthase (NOS2) as therapeutic targets in individuals with TAAD. We show that Adamts1 is a major mediator of vascular homeostasis, given that genetic haploinsufficiency of Adamts1 in mice causes TAAD similar to MFS. Aortic nitric oxide and Nos2 levels were higher in Adamts1-deficient mice and in a mouse model of MFS (hereafter referred to as MFS mice), and Nos2 inactivation protected both types of mice from aortic pathology. Pharmacological inhibition of Nos2 rapidly reversed aortic dilation and medial degeneration in young Adamts1-deficient mice and in young or old MFS mice. Patients with MFS showed elevated NOS2 and decreased ADAMTS1 protein levels in the aorta. These findings uncover a possible causative role for the ADAMTS1-NOS2 axis in human TAAD and warrant evaluation of NOS2 inhibitors for therapy.

    The incidence and outcome of the acute respiratory distress syndrome in children are not well-known, especially under current ventilatory practices. The goal of this study was to determine the incidence, etiology, and outcome of acute respiratory distress syndrome in the pediatric population in the setting of lung protective ventilation. A 1-yr, prospective, multicenter, observational study in 12 geographical areas of Spain (serving a population of 3.77 million ≤ 15 yrs of age) covered by 21 pediatric intensive care units. All consecutive pediatric patients receiving invasive mechanical ventilation and meeting American-European Consensus Criteria for acute respiratory distress syndrome. None. Data on ventilatory management, gas exchange, hemodynamics, and organ dysfunction were collected. A total of 146 mechanically ventilated patients fulfilled the acute respiratory distress syndrome definition, representing a incidence of 3.9/100,000 population ≤ 15 yrs of age/yr. Pneumonia and sepsis were the most common causes of acute respiratory distress syndrome. At the time of meeting acute respiratory distress syndrome criteria, mean PaO2/FIO2 was 99 mm Hg ± 41 mm Hg, mean tidal volume was 7.6 mL/kg ± 1.8 mL/kg predicted body weight, mean plateau pressure was 27 cm H2O ± 6 cm H2O, and mean positive end-expiratory pressure was 8.9 cm ± 2.9 cm H2O. Overall pediatric intensive care unit and hospital mortality were 26% (95% confidence interval 19.6-33.7) and 27.4% (95% confidence interval 20.8-35.1), respectively. At 24 hrs, after the assessment of oxygenation under standard ventilatory settings, 118 (80.8%) patients continued to meet acute respiratory distress syndrome criteria (PaO2/FIO2 104 mm Hg ± 36 mm Hg; pediatric intensive care units mortality 30.5%), whereas 28 patients (19.2%) had a PaO2/FIO2 >200 mm Hg (pediatric intensive care units mortality 7.1%) (p = .014).
