    Full Text Available FUNDAMENTO: A obesidade é um fator de risco para muitas complicações médicas; a pesquisa médica demonstrou que as alterações hemodinâmicas, morfológicas e funcionais estão correlacionadas com a duração e gravidade da obesidade. OBJETIVO: O presente estudo determinou a influência do tempo de exposição à obesidade induzida por dieta com alto teor de gordura no colágenos tipo I e III miocárdico. MÉTODOS: Ratos machos com trinta dias de idade, da raça Wistar, foram distribuídos aleatoriamente em dois grupos: um grupo de controle (C alimentado com ração padrão e um grupo de ratos obesos (Ob alternadamente alimentados com uma de quatro dietas palatáveis ricas em gordura. Cada dieta foi mudada diariamente, e os ratos foram mantidos em suas respectivas dietas por 15 (C15 e Ob15 e 30 (C30 e Ob30 semanas consecutivas. A obesidade foi determinada pelo índice de adiposidade. RESULTADOS: O grupo Ob15 foi similar ao grupo C15 em relação à expressão de colágeno miocárdico tipo I; contudo, a expressão no grupo Ob30 foi menor do que no grupo C30. O tempo de exposição à obesidade foi associado com uma redução de colágeno do tipo I no grupo Ob30, quando comparado com o Ob15. A obesidade não afetou a expressão do colágeno tipo III. CONCLUSÃO: Este estudo mostrou que o tempo de exposição à obesidade por 30 semanas induzida por uma dieta rica em gordura insaturada causou uma redução na expressão do colágeno miocárdico tipo I em ratos obesos. No entanto, nenhum efeito foi observado em relação à expressão do colágeno miocárdico tipo III

    Full Text Available Se realizó una revisión del tema relacionado con la hipertensión arterial en el paciente diabético tipo 2, con el objetivo de actualizar algunos elementos particulares en este grupo de pacientes. Se plantea que su prevalencia es considerablemente más alta que en la población no diabética, donde la hiperinsulinemia y la disfunción endotelial cobran un papel protagónico en su etiopatogenia. La hipertensión arterial en estos pacientes clínicamente se manifiesta como un patrón non dipper, lo que incrementa la morbimortalidad por esta entidad. El tratamiento medicamentoso es habitualmente necesario, y se usan como drogas de primera línea los inhibidores de la enzima convertidora, los antagonistas de los receptores de angiotensina ll y los calcioantagonistas, aunque se pueden utilizar también los diuréticos tiacídicos a dosis bajas.Authors made a review of the topic related to arterial high blood pressure in the patient presenting with Type 2 diabetes mellitus to update some particular elements in this group of patients. We propose that its prevalence is higher than that present in non-diabetic population, where the hyperinsulinism and the endothelial dysfunction have a leading role in its ethiopathogenesis. The arterial high blood pressure in these patients clinically is manifested as a non-dipper pattern increasing the morbidity and mortality. Drug therapy is commonly necessary and as first line-drugs are used the converting-enzyme inhibitors, the agiotensin-II receptors antagonists, and the antagonists-calcium, although the low-dose thiacidic diuretics.

    Thirty-eight patients with stage III, IV oral cancer were treated by preoperative chemoradiotherapy using superselective intraarterial infusion via the superficial temporal artery. Radiotherapy (total dose: 40 Gy) and chemotherapy using CBDCA (total dose: 460 mg/m{sup 2}) were performed daily, followed by surgery. Catheter-insertion of 34 patients was done successfully. Four catheter insertions were not done successfully because of the anomaly of the artery such as common trunk of the lingual artery and the facial artery. The clinical effects were CR in 9 patients (26.5%) and PR in 25 (73.5%), and histopathological effects after surgery were grade III, IV in 10 (29.4%), grade IIb in 23 (67.6%), and grade IIa in 2 (5.8%). The 5-year cumulative survival rate was 67.8%. This superselective intra arterial infusion method could be the technique of choice for the treatment of oral cancer. (author)

    Triglyceride-rich lipoproteins have emerged as causal risk factors for developing coronary heart disease independent of low-density lipoprotein cholesterol levels. Apolipoprotein C-III (ApoC-III) modulates triglyceride-rich lipoprotein metabolism through inhibition of lipoprotein lipase and hepatic uptake of triglyceride-rich lipoproteins. Mutations causing loss-of-function of ApoC-III lower triglycerides and reduce coronary heart disease risk, suggestive of a causal role for ApoC-III. Little data exist about the relationship of ApoC-III, triglycerides, and atherosclerosis in patients with type 2 diabetes mellitus (T2DM). Here, we examined the relationships between plasma ApoC-III, triglycerides, and coronary artery calcification in patients with T2DM. Plasma ApoC-III levels were measured in a cross-sectional study of 1422 subjects with T2DM but without clinically manifest coronary heart disease. ApoC-III levels were positively associated with total cholesterol (Spearman r=0.36), triglycerides (r=0.59), low-density lipoprotein cholesterol (r=0.16), fasting glucose (r=0.16), and glycosylated hemoglobin (r=0.12; Ptriglycerides (Tobit regression ratio, 1.43; 95% confidence interval, 0.94-2.18; P=0.086) and separately for very low-density lipoprotein cholesterol (Tobit regression ratio, 1.14; 95% confidence interval, 0.75-1.71; P=0.53). In persons with T2DM, increased plasma ApoC-III is associated with higher triglycerides, less favorable cardiometabolic phenotypes, and higher coronary artery calcification, a measure of subclinical atherosclerosis. Therapeutic inhibition of ApoC-III may thus be a novel strategy for reducing plasma triglyceride-rich lipoproteins and cardiovascular risk in T2DM. © 2015 American Heart Association, Inc.

    Occipital condylar fractures (OCF) are rare and have a high mortality rate. We report a patient with OCF who presented with acute hydrocephalus and died from diffuse vasospasm secondary to vertebral artery injury. A 45-year-old man fell 20 feet from a deer stand and landed on his head. CT showed a type III OCF continuing to the anterior rim of the foramen magnum on the left, with a bone fragment pushing into the medulla, causing hydrocephalus. The patient was stabilized, and a four-vessel arteriogram showed diffuse vasospasm with complete occlusion of the left vertebral artery at the level of the OCF. To our knowledge, this is the first documented case of the conjunction of OCF, hydrocephalus, and vasospasm. (orig.)

    The objective of the study is to examine the feasibility of hepatic artery resection (HAR) without subsequent reconstruction (RCS) in specified patients of Bismuth type III and IV hilar cholangiocarcinoma. We retrospectively reviewed 63 patients who underwent hepatic artery resection for Bismuth type III and IV hilar cholangiocarcinoma. These patients were subsequently enrolled into two groups based on whether the artery reconstruction was conducted. Postoperative morbidity and mortality, and long-term survival outcome were compared between the two groups. There were 29 patients in HAR group and 34 patients in the HAR + RCS group. Patients with hepatic artery reconstruction tended to have longer operative time (545.6 ± 143.1 min vs. 656.3 ± 192.8 min; P = 0.013) and smaller tumor size (3.0 ± 1.1 cm vs. 2.5 ± 0.9 cm; P = 0.036). The R0 resection margin was comparable between the HAR group and HAR + RCS group (86.2 vs. 85.3%; P > 0.05). Twelve patients (41.4%) with 24 complications in HAR group and 13 patients (38.2%) with 25 complications in HAR + RCS group were recorded (P = 0.799). The postoperative hepatic failure rate (13.8 vs. 5.9%) and postoperative mortality rate (3.4% vs. 2.9%) were also comparable between the two groups. In the HAR group, the overall 1-, 3-, and 5-year survival rates were 72, 41, and 19%, respectively; while in the HAR + RCS group, the overall 1-, 3-, and 5-year survival rates were 79, 45, and 25%, respectively (P = 0.928). Hepatic artery resection without reconstruction is also a safe and feasible surgical procedure for highly selected cases of Bismuth type III and IV hilar cholangiocarcinoma.

    2005-01-01

    Recently, daily concurrent chemoradiotherapy using new superselective intra-arterial infusion via superficial temporal arterial artery is attracting attention. The catheter with curved tip is inserted superselectively to the feeding artery of the tumor via the superficial temporal artery, allowing long-term catheterization. Forty-one patients with stage III, IV oral cancer were treated. Radiotherapy (total dose: 40 Gy/4 weeks) and superselective intra-arterial infusion chemotherapy using docetaxel (total dose: 60 mg/m 2 , 15 mg/m 2 /week) and cisplatin (total dose: 100 mg/m 2 , 5 mg/m 2 /day) were concurrently performed daily, followed by surgery. In 35 patients, intra-arterial infusion was successful (success rate: 85.4%) and no major complication was observed. The clinical effects were complete response (CR) in 29 patients (82.9%), and pathological effects of resected tumor after surgery were pathological CR in 31 (88.6%). This method promises to be a new strategy of choice for the treatment of oral cancer. (author)

  16. New Therapeutic Agent against Arterial Thrombosis: An Iridium(III-Derived Organometallic Compound

    Chih-Wei Hsia

    2017-12-01

    Full Text Available Platelet activation plays a major role in cardio and cerebrovascular diseases, and cancer progression. Disruption of platelet activation represents an attractive therapeutic target for reducing the bidirectional cross talk between platelets and tumor cells. Platinum (Pt compounds have been used for treating cancer. Hence, replacing Pt with iridium (Ir is considered a potential alternative. We recently developed an Ir(III-derived complex, [Ir(Cp*1-(2-pyridyl-3-(2-hydroxyphenylimidazo[1,5-a]pyridine Cl]BF4 (Ir-11, which exhibited strong antiplatelet activity; hence, we assessed the therapeutic potential of Ir-11 against arterial thrombosis. In collagen-activated platelets, Ir-11 inhibited platelet aggregation, adenosine triphosphate (ATP release, intracellular Ca2+ mobilization, P-selectin expression, and OH· formation, as well as the phosphorylation of phospholipase Cγ2 (PLCγ2, protein kinase C (PKC, mitogen-activated protein kinases (MAPKs, and Akt. Neither the adenylate cyclase inhibitor nor the guanylate cyclase inhibitor reversed the Ir-11-mediated antiplatelet effects. In experimental mice, Ir-11 prolonged the bleeding time and reduced mortality associated with acute pulmonary thromboembolism. Ir-11 plays a crucial role by inhibiting platelet activation through the inhibition of the PLCγ2–PKC cascade, and the subsequent suppression of Akt and MAPK activation, ultimately inhibiting platelet aggregation. Therefore, Ir-11 can be considered a new therapeutic agent against either arterial thrombosis or the bidirectional cross talk between platelets and tumor cells.

    2017-08-01

    We investigated the effects of neoadjuvant chemotherapy administered via bronchial arterial infusion (BAI) on unresectable stage III lung squamous cell carcinoma (SCC). This was a single-arm retrospective study of chemotherapy with gemcitabine plus cisplatin (GP) administered via BAI to patients with unresectable lung SCC. Data regarding the post-treatment response rate, downstage rate, and surgery rate, as well as progression-free survival (PFS), overall survival (OS), quality of life, and post-BAI side effects were collected. A total of 36 patients were enrolled in this study between August 2010 and May 2014. The response rate was 72.2%, and the downstage rate was 22.2%. Among the patients who were downstaged, 16 (44.4%) patients were because of their T stage, and 5 (13.9%) patients were downstaged due to to their N stage. The surgery rate was 52.8%, the 1-year survival rate was 75.4%, and the 2-year survival rate was 52.1%. The median PFS was 14.0 months [95% confidence interval (CI): 8.6-19.4], and the median OS was 25.0 months (95% CI: 19.1-30.9). The quality of life was significantly improved, and the chemotherapy was well tolerated. Compared with intravenous neoadjuvant chemotherapy, BAI chemotherapy significantly improved the surgery rate, prolonged PFS and OS, and improved the quality of life in patients with unresectable stage III lung SCC.

    Full Text Available O carcinoma de células escamosas (CCE é uma neoplasia epitelial maligna que acomete cães e diversas outras espécies, incluindo a humana. O CCE afeta vários sítios anatômicos e pode desenvolver metástase. O objetivo deste estudo foi a caracterização das fibras de colágenos tipos I e III no estroma do CCE cutâneo de cães. Para este trabalho, utilizaram-se 44 amostras de pele incluídas em parafina e que tiveram prévio diagnóstico de CCE. As amostras foram processadas histologicamente e coradas com hematoxilina/eosina para confirmação do diagnóstico e classificação do grau de diferenciação tumoral e com a coloração histoquímica de picrosirius para observação dos colágenos tipos I e III. O colágeno tipo III mostrou maior expressão nos CCEs cutâneos bem diferenciados. O papel do colágeno do tipo III nas neoplasias não está bem esclarecido, e outros fatores além do grau de diferenciação celular podem estar envolvidos em sua expressão e determinar sua importância na biologia tumoral.

    Apolipoprotein C-III (apoC-III) is a key regulator of triglyceride metabolism. Elevated triglyceride-rich lipoproteins and apoC-III levels are causally linked to coronary artery disease (CAD) risk. The mechanism(s) through which apoC-III increases CAD risk remains largely unknown. The aim was to confirm the association between apoC-III plasma levels and CAD risk and to explore which lipoprotein subfractions contribute to this relationship between apoC-III and CAD risk. Plasma apoC-III levels were measured in baseline samples from a nested case-control study in the European Prospective Investigation of Cancer (EPIC)-Norfolk study. The study comprised 2711 apparently healthy study participants, of whom 832 subsequently developed CAD. We studied the association of baseline apoC-III levels with incident CAD risk, lipoprotein subfractions measured by nuclear magnetic resonance spectroscopy and inflammatory biomarkers. ApoC-III levels were significantly associated with CAD risk (odds ratio, 1.91; 95% confidence interval, 1.48-2.48 for highest compared with lowest quintile), retaining significance after adjustment for traditional CAD risk factors (odds ratio, 1.47; 95% confidence interval, 1.11-1.94). ApoC-III levels were positively correlated with triglyceride levels, ( r =0.39), particle numbers of very-low-density lipoprotein ( r =0.25), intermediate-density lipoprotein ( r =0.23), small dense low-density lipoprotein ( r =0.26), and high-sensitivity C-reactive protein ( r =0.15), whereas an inverse correlation was observed with large low-density lipoprotein particle number ( r =-0.11), P C-reactive protein. ApoC-III levels are significantly associated with incident CAD risk. Elevated levels of remnant lipoproteins, small dense low-density lipoprotein, and low-grade inflammation may explain this association. © 2017 American Heart Association, Inc.

    Full Text Available The initial step in calculating the Standardized Precipitation Index (SPI is to determine a probability density function (pdf that describes the precipitation series under analysis. Once this pdf is determined, the cumulative probability of an observed precipitation amount is computed. The inverse normal function is then applied to the cumulative probability. The result is the SPI. This article assessed the changes in SPI final values, when computed based on Gamma 2-parameters (Gam and Pearson Type III (PE3 distributions (SPIGam and SPIPE3, respectively. Monthly rainfall series, available from five weather stations of the State of São Paulo, were chosen for this study. Considering quantitative and qualitative assessments of goodness-of-fit (evaluated at 1-, 3-, and 6-months precipitation totals, the PE3 distribution seems to be a better choice than the Gam distribution, in describing the long-term rainfall series of the State of São Paulo. In addition, it was observed that the number of SPI time series that could be seen as normally distributed was higher when this drought index was computed from the PE3 distribution. Thus, the use of the Pearson type III distribution within the calculation algorithm of the SPI is recommended in the State of São Paulo.O cálculo do Índice Padronizado de Precipitação (IPP inicia-se com a adoção de uma distribuição paramétrica (dp utilizada para a estimativa das probabilidades de ocorrência associadas a uma série de precipitação pluvial.

    Full Text Available We added hydrotherapy to 50 patients with spinal muscular atrophy (SMA who were being treated with individual conventional physiotherapy. Hydrotherapy was performed at an approximate temperature of 30 degrees Celsius, twice a week, for thirty minutes in children and for forty-five minutes in adults during a 2-year period. The outcome derived from this combined modality of treatment was rated according to physiotherapeutic evaluations, the MMT (Manual Muscular Test, and the Barthel Ladder. Patients were reevaluated at 2-month intervals. After two years of ongoing treatment, we were able to observe that the deformities in hip, knee and foot were progressive in all SMA Type II patients, and in some Type III. Muscle strength stabilized in most SMA Type III patients, and improved in some. MMT was not done in SMA Type II. In all patients we were able to detect an improvement in the Barthel Ladder scale. This study suggests that a measurable improvement in the quality of daily living may be obtained in patients with SMA Types II and III subjected to conventional physiotherapy when associated with hydrotherapy.A hidroterapia foi realizada em SO pacientes com atrofia muscular espinhal, os quais foram também tratados com fisioterapia individual convencional.

    Purpose: We performed superselective intra-arterial infusion chemotherapy (SIC) according to a protocol in which drug distribution is evaluated by the use of interventional radiology (IVR)-computed tomography (CT) system, and the chemotherapy is combined with medium-dose conformal radiation therapy (CRT). We analyzed retrospectively the factors that affect the midterm survival ratio, including local response, for stage III and IV squamous cell carcinomas of the oral cavity. Materials and methods: Forty consecutive patients with stage III and IV squamous cell carcinomas of the oral cavity and who had undergone both SIC and CRT were enrolled. A microcatheter was placed in the appropriate feeding artery of the tumor and cisplatin (50 mg/body) was infused twice. CRT was administered with a dual-energy (4 and 10 MV) linear accelerator. The total and daily doses delivered were 30 and 2.0 Gy, respectively. Histopathologic effects were classified into five grades: grade 0 or 1 was defined as a poor response, and grade II or higher as a good response. Age, sex, stage, local response to treatment, mode of invasion and lymph node metastasis were analyzed, and differences in the midterm survival ratio were assessed. Results: The 3-year survival ratio of the 40 cases was 67%. A good local response (III or IV) was achieved in 75% of the cases. The survival ratio of the good local response group was significantly better than that of the poor response group (p = 0.04). Mode of invasion (p = 0.03) and lymph node metastasis (p = 0.01) were also predictive of survival. In the multivariable analysis of survival, however, no variables including good local response (p = 0.12), were predictive. Conslusion: Our new protocol improved local response, but it did not contribute to the survival ratio

Conclusion: Retrograde superselective intra-arterial chemotherapy and daily concurrent radiotherapy for stage III and IV oral cancer provided good overall survival and local control

  10. Doppler-guided hemorrhoidal artery ligation (DG-HAL): a safe treatment of II-III degree hemorrhoids for all patients. Could it be potentially also good prophylaxis?

    Testa, A; Torino, G

    2010-06-01

    Doppler-guided hemorrhoidal artery ligation (HAL Doppler) is an innovative hemorrhoid treatment mainly utilised for II-III degree where bleeding is a predominant symptom. This procedure aims at dearterialization of the internal hemorrhoidal plexus by ligation of the terminal branches of the superior rectal artery detected using a special proctoscope and ultrasound system; the procedure is performed entirely above the dentate line, so it is genuinely painless. The aim of this study was to evaluate the efficacy, safety and invasivity of HAL Doppler technique to treat II and III degree hemorrhoids. The authors treated 148 patients, from May 2002 to December 2007, principally affected by II-III degree hemorrhoids characterized by bleeding and pain at evacuation. These patients were examined in a retrospective observational study of 128 patients, 86% of the group. Follow-up varied from 5 up to 72 months with an average observation time of 36.5 months. Success was registered in 90% of patients affected by II-III degree hemorrhoids and the absence of major complications (hemorrhage, incontinence, stenosis, perforation, sepsis). The authors suggest the safety, efficacy and low invasity of HAL Doppler for treatment of II-III degree hemorrhoids, which also found in the literature, and highlight its use in treating patients with unhealthy conditions which are a contraindication to the usual surgical treatments. Moreover, they suppose the use of HAL Doppler in low degree hemorrhoids as a therapeutic and also prophylactic rule of advanced degree.

    The field of electronic processing of the ceramic piezoelectric type imported powdered led to the production of ceramics with 97% of theoretical density, homogeneous microstructure with great potential for applications in piezoelectric devices such as electro acoustic transducers. However, the production of electronic ceramics National piezoelectric type is not yet able to have as raw material zirconate titanate Lead (PZT) 100% made in Brazil. Thus, this is used for supply of domestic production, the zirconium oxide. In this work, both post PZT types I and III, imported, were uniaxially pressed at 70 MPa and sintered at 1200 and 1250 deg C for 3 hours. Hardness measurements were performed by micro indentation, X-ray diffraction analysis and Scanning Electron Microscopy. The hardness of PZT I was 393 HV. (author)

    The main purpose of this work is to obtain the fluence of fast neutrons recorded within four specimens of carbon steel, similar to the material having the vessels of the BWR reactors of the nuclear power plant of Laguna Verde when subjected to neutron flux in a experimental facility of the TRIGA Mark III reactor, calculating an irradiation time to age the material so accelerated. For the calculation of the neutron flux in the specimens was used the Monte Carlo code MCNP5. In an initial stage, three sheets of natural molybdenum and molybdenum trioxide (MoO{sub 3}) were incorporated into a model developed of the TRIGA reactor operating at 1 M Wth, to calculate the resulting activity by setting a certain time of irradiation. The results obtained were compared with experimentally measured activities in these same materials to validate the calculated neutron flux in the model used. Subsequently, the fast neutron flux received by the steel specimens to incorporate them in the experimental facility E-16 of the reactor core model operating at nominal maximum power in steady-state was calculated, already from these calculations the irradiation time required was obtained for values of the neutron flux in the range of 10{sup 18} n/cm{sup 2}, which is estimated for the case of Laguna Verde after 32 years of effective operation at maximum power.

    2006-01-01

    Superselective intra-arterial chemotherapy via the superficial temporal artery has become feasible for daily concurrent radiotherapy and chemotherapy for head and neck cancer. This novel method was used for oral cancer, and its efficacy was evaluated. Treatment consisted of superselective intra-arterial infusions (Docetaxel (DOC) total 60 mg/m 2 , Cisplatin (CDDP) total 100 mg/m 2 ) and concurrent radiotherapy (total 40 Gy) for four weeks as preoperative therapy. Thirty-four patients with stage III and IV oral cancer received surgery after this treatment, and pathological CR was obtained in 31 patients (91%). The possibility of organ preservation for advanced oral cancer was evaluated from this result. Patients with oral cancer stage III and IV were treated for four-week daily concurrent chemoradiotherapy, and the clinical response was evaluated after treatment. Clinical CR of primary sites was obtained in 15 patients, and the same treatment was continued one or two weeks. Thirteen patients (80%) were disease-free in the primary sites, and two (20%) relapsed. Two patients died of distant metastasis, and one died of local recurrence. This method can preserve organs and minimize functional disturbance, thus contributing to patient QOL. (author)

    Understanding the anatomy of the pterygomaxillary junction region helps prevent blood loss in Le Fort I osteotomy. Here, we determined the location of the descending palatine artery and the structure of the pterygomaxillary region. The study group consisted of 82 Japanese patients with mandibular prognathism and asymmetry, with and without maxillary retrognathism or asymmetry. A total of 164 sides were measured and divided into right versus left, men versus women, and bimaxillary osteotomy (B) versus mandibular osteotomy (S). Lateral and frontal cephalograms and computed tomography (CT) were analysed for all patients. The relationship between the cephalometric measurements and the measurements of the descending palatine artery and pterygoid plate (PP) were assessed. There were no significant correlations between measurements of cephalograms and those of the descending palatine artery and PPs. There were significant differences between right and left in lateral plate length (p=0.0014) and thickness of PP (p=0.0047). There were significant differences between men and women in right width of PP (p=0.0034), right thickness of PP (p=0.0063), left posterior length (p=0.0196), and left thickness of PP (p=0.0279). The B group had a shorter anterior length than the S group (right: ppalatine artery and the morphology of the PPs were not significantly associated with any cephalometric measurements. CT examination is necessary to recognize the anatomy of pterygomaxillary region and the exact positions of descending palatine artery before Le Fort I osteotomy.

    To evaluate the safety and efficacy of the XIENCE V everolimus-eluting stent compared to the TAXUS paclitaxel-eluting stent in small vessels. The XIENCE V everolimus-eluting stent (EES) has been shown to improve angiographic and clinical outcomes after percutaneous myocardial revascularization, but its performance in small coronary arteries has not been investigated. In this pooled analysis, we studied a cohort of 541 patients with small coronary vessels (reference diameter SPIRIT II and SPIRIT III studies. TAXUS Express (73% of lesions) and TAXUS Liberté (27% of lesions) paclitaxel-eluting stents (PES) were used as controls in SPIRIT II. In SPIRIT III, Taxus Express(2) PES was the control. Mean angiographic in-stent and in-segment late loss was significantly less in the EES group compared with the PES group, (0.15 +/- 0.37 mm vs. 0.30 +/- 0.44 mm; P = 0.011 for in-stent; 0.10 +/- 0.38 mm vs. 0.21 +/- 0.34 mm; P = 0.034 for in-segment). EES also resulted in a significant reduction in composite major adverse cardiac events at 1 year (19/366 [5.2%] vs. 17/159 [10.7%]; P = 0.037), due to fewer non-Q-wave myocardial infarctions and target lesion revascularizations. At 1 year, the rate of non-Q-wave myocardial infarction was significantly lower in the EES group compared with that of the PES group (6/366 [1.6%] vs. 8/159 [5.0%]; P = 0.037). In patients with small vessel coronary arteries, the XIENCE V EES was superior to the TAXUS PES. (c) 2010 Wiley-Liss, Inc.

    Intracarotid arterial infusion of nonionic, low-osmolal iohexol contrast medium has been associated with increased intracranial hemorrhage in a rat middle cerebral artery occlusion model compared with saline infusion. Iso-osmolal iodixanol (290 mOsm/kg H2O) infusion demonstrated smaller infarcts and less intracranial hemorrhage compared with low-osmolal iopamidol and saline. No studies comparing iodinated radiographic contrast media in human stroke have been performed, to our knowledge. We hypothesized that low-osmolal contrast media may be associated with worse outcomes compared with iodixanol in the Interventional Management of Stroke III Trial (IMS III). We reviewed prospective iodinated radiographic contrast media data for 133 M1 occlusions treated with endovascular therapy. We compared 5 prespecified efficacy and safety end points (mRS 0-2 outcome, modified TICI 2b-3 reperfusion, asymptomatic and symptomatic intracranial hemorrhage, and mortality) between those receiving iodixanol (n = 31) or low-osmolal contrast media (n = 102). Variables imbalanced between iodinated radiographic contrast media types or associated with outcome were considered potential covariates for the adjusted models. In addition to the iodinated radiographic contrast media type, final covariates were those selected by using the stepwise method in a logistic regression model. Adjusted relative risks were then estimated by using a log-link regression model. Of baseline or endovascular therapy variables potentially linked to outcome, prior antiplatelet agent use was more common and microcatheter iodinated radiographic contrast media injections were fewer with iodixanol. Relative risk point estimates are in favor of iodixanol for the 5 prespecified end points with M1 occlusion. The percentage of risk differences are numerically greater for microcatheter injections with iodixanol. While data favoring the use of iso-osmolal iodixanol for reperfusion of M1 occlusion following IV rtPA are

We aimed to evaluate the effectiveness of a suture-fixation mucopexy procedure by comparing with Doppler-guided hemorrhoidal artery ligation (DGHAL in the management of patients with grade III hemorrhoids. Methods. This was a randomized controlled trial. One hundred patients with grade III hemorrhoids were randomly assigned to receive suture-fixation mucopexy (n=50 or DGHAL (n=50. Outcome assessments were performed at 2 weeks, 12 months, and 24 months. Assessments included resolution of clinical symptoms, postoperative complications, duration of hospitalization, and total costs. Results. At 2 weeks, one (2% patient in suture-fixation group and four (8% patients in DGHAL group had persistent prolapsing hemorrhoids. Postoperative bleeding was observed in two patients (4% in suture-fixation group and one patient in DGHAL group. There was no significant difference in short-term recurrence between groups. Postoperative complications and duration of hospitalization were comparable between the two groups. Rates of recurrence of prolapse or bleeding at 12 months did not differ between groups. However, recurrence of prolapse at 24 months was significantly more common in DGHAL group (19.0% versus 2.3%, p=0.030. Conclusions. Compared with DGHAL, the suture-fixation mucopexy technique had comparable short-term outcomes and favorable long-term outcomes.

    We tested the hypothesis that frequency analysis of the anatomic zones affected by single anterior (A), posterior (P), and middle (M) cerebral artery (CA), multivessel, and watershed infarcts will disclose specific sites (peak zones) most frequently involved by each type, sites most frequently injured by multiple different types (vulnerable zones), and overlapping sites of equal relative frequency for two or more different types of infarct (equal frequency zones). We adopted precise definitions of each vascular territory. CT and MRI studies of 50 MCA, 20 ACA-MCA, three PCA-MCA, and 30 parasagittal watershed infarcts were mapped onto a standard template. Relative infarct frequencies in each zone were analyzed within and across infarct types to identify the centers and peripheries of each, vulnerable zones, and equal frequency zones. These data were then correlated with the prior analysis of 47 ACA, PCA, dual ACA-PCA, and ACA-PCA-MCA infarcts. Zonal frequency data for MCA and watershed infarcts, the sites of peak infarct frequency, the sites of vulnerability to diverse infarcts, and the overlapping sites of equal infarct frequency are tabulated and displayed in standardized format for direct comparison of different infarcts. This method successfully displays the nature, sites, and extent of individual infarct types, illustrates the shifts in zonal frequency and lesion center that attend dual and triple infarcts, and clarifies the relationships among the diverse types of infarct.

    Full Text Available Paciente de 39 anos, portador de hipertensão arterial não controlada, submetido a cirurgia para tratamento de dissecção aguda de aorta tipo I. Devido ao grande envolvimento do óstio coronário direito pela dissecção aórtica, optou-se pela ressecção da porção comprometida do vaso, com interposição de tubo não valvulado de Dacron na aorta ascendente, suspensão da valva aórtica e ligadura do óstio da artéria coronária direita. Como não havia presença de aterosclerose no ramo interventricular anterior e na artéria coronária direita, decidimos realizar um enxerto venoso entre as artérias. O enxerto intercoronário apresentou bom funcionamento e todo o território dependente da coronária direita manteve boa contratilidade. O paciente recebeu alta hospitalar em boas condições clínicas, com função rniocárdica preservada.A thirty nine-year-old patient presenting arterial hypertension was operated upon for type I acute aortic dissection. Due to important alterations in the ascendent aorta with involvement of the right coronary ostium, the surgical procedure included resection of the segment of aorta containing the intimal tear and replacement with a Dacron prosthesis, suspension of the aortic valve and ligadure of the right coronary ostium. Technical difficulties brought the necessity of a different approach for the myocardium revascularization. Instead of the traditional described procedures, an intercoronary venous graft was put between the anterior interventricular artery (branch of the left coronary artery and the right coronary artery. The intercoronary graft presented a good flow since the begining, keeping a good myocardial contratility. Patient left the hospital in a good clinical condition, with preserved myocardial function. Intercoronary graft should be an efficient alternative for revascularization of a corohary artery involved by aortic dissections.

Los sujetos del estudio son 14 adolescentes atendidos en una clínica para la diabetes en Fortaleza, Ceará, Brasil, de junio a octubre de 2008. La recolección de los datos se hizo a través de entrevistas semi-estructuradas y se organizaron de acuerdo al análisis de contenido de Morse y Field. Se observó que el descubrimiento de la diabetes fue un momento difícil para los adolescentes debido a los cambios que tuvieron que hacer como el control terapéutico. Hacer una dieta adecuada es muy difícil como consecuencia de estímulos internos y externos a que están sometidos y a las dificultades financieras. Los adolescentes tienen el apoyo de la familia y amigos para su tratamiento diario. Además, les gusta el servicio realizado por los profesionales de salud de la clínica. Sin embargo, hay mucho que mejorar como enfermeras en la valorización de las experiencias de la vida de los adolescentes con diabetes, como la identificación de factores que interfieren en el control metabólico.

Materiales y métodos: la escala se aplicó a 200 participantes con diabetes mellitus tipo 2. Para validar el constructo se realizó la extracción de factores con componentes principales y rotación Varimax, con Eigenvalores por arriba de 1 y cargas de factor mayores a ,30. Resultados: seis reactivos fueron eliminados del análisis por mostrar correlación negativa con la correlación total de la escala. El análisis de componentes principales inicial reveló nueve factores con una variación explicada de 65,29%. Sin embargo, no se consideraron tres factores por contener cada uno de ellos solamente un reactivo. Por tanto, la escala final se acepta con 38 reactivos. El coeficiente de confiabilidad Alfa de Cronbach fue de, 93. Discusión: el análisis reveló seis factores, uno más de lo reportado por Roy, y con mayor variación explicada. Algunos reactivos parecen no ser bien comprendidos por los participantes. Conclusiones: este artículo aporta una aproximación metodológica para explorar la adecuación de un instrumento a una población diferente para la que originalmente fue diseñado. Se concluye que la escala tiene consistencia interna y validez de constructo incipiente, los datos reportados en este estudio deben tomarse en cuenta con cautela. Es conveniente revisar de nuevo los reactivos y adecuarlos a la cultura particular, y probar la escala de nuevo con pacientes con enfermedades crónicas degenerativas a fin de contar con instrumentos culturalmente equivalentes.

    Full Text Available RESUMOObjetivou-se com este trabalho comparar o padrão de crescimento, mediante ajustes das respectivas curvas de crescimento por modelos não lineares, bem como estudar o desenvolvimento de cortes de carcaça em relação ao peso da carcaça em diferentes genótipos de frangos tipo caipira. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos da linhagem Redbro: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. As aves foram alojadas em 28 boxes, sendo 30 aves/boxe, em galpão de alvenaria com acesso a um piquete de 45m², com quatro repetições. O peso corporal individual dos frangos foi medido ao nascer, aos 14, 28, 42, 56, 70 e 84 dias de idade. Para a determinação das curvas de crescimento do peso corporal das aves, os dados coletados foram avaliados por meio dos modelos não lineares: Brody, Gompertz, Logístico, Richards e von Bertalanffy. Foi empregado o PROC NLIN do SAS, utilizando-se o método interativo de Gauss-Newton. Os critérios usados para escolha do modelo de melhor ajuste da curva de crescimento foram o coeficiente de determinação, o desvio padrão assintótico, o desvio médio absoluto dos resíduos e o índice assintótico. As análises para obtenção dos coeficientes alométricos foram realizadas por meio do PROC GLM do SAS para os genótipos Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor. Foram avaliados os pesos da carcaça, do peito, das coxas, das sobrecoxas, das pernas e das asas das aves abatidas aos 85 dias de idade. Apenas as equações propostas por Gompertz, von Bertalanffy e Logístico atingiram a convergência, e o modelo proposto por von Bertalanffy foi o mais adequado para descrever o crescimento dos genótipos de frangos caipiras. Todos os cortes avaliados apresentaram crescimento tardio em relação ao peso da carcaça em genótipos de frangos tipo caipira.

    The article addresses the theoretical generalization of the clinical study of non-alcoholic steatohepatitis peculiarities in comorbidity with obesity and chronic kidney disease of the І-ІІІ stage, characterized by higher frequency and intensity of clinical and biochemical syndromes, the manifestation of which is likely to increase the occurrence of secondary arterial hypertension (portal hypertension syndromes, cholestasis, mesenchymal inflammation). Comorbid course of non-alcoholic steatohepatitis with chronic kidney disease is characterized by higher degree of liver steatosis compared to the patients with only non-alcoholic steatohepatitis (p<0.05), and a higher diagnostic threshold of the hepatorenal index values, which correlates with the Steato-test index (p<0.001) with strong interdependence.

    Multidetector coronary computed tomographic angiography (CCTA) demonstrates high accuracy for the detection and exclusion of coronary artery disease (CAD) and predicts adverse prognosis. To date, opportunity costs relating the clinical and economic outcomes of CCTA compared with other methods of diagnosing CAD, such as myocardial perfusion single-photon emission computed tomography (SPECT), remain unknown. An observational, multicenter, patient-level analysis of patients without known CAD who underwent CCTA or SPECT was performed. Patients who underwent CCTA (n = 1,938) were matched to those who underwent SPECT (n = 7,752) on 8 demographic and clinical characteristics and 2 summary measures of cardiac medications and co-morbidities and were evaluated for 9-month expenditures and clinical outcomes.

    Full Text Available FUNDAMENTO: Tem sido sugerido que o polimorfismo da haptoglobina pode influenciar na patogênese das complicações microvasculares e macrovasculares em pacientes diabéticos. OBJETIVO: O objetivo principal deste estudo transversal foi de realizar uma investigação da existência ou não de uma associação entre os genótipos de haptoglobina e a prevalência de eventos isquêmicos cardiovasculares (angina estável, angina instável e infarto agudo do miocárdio, hipertensão arterial sistêmica, hipertensão refratária, obesidade e dislipidemia em 120 pacientes com diabete melito tipo 2, seguidos no Hospital Universitário da Unicamp, em Campinas, Estado de São Paulo. MÉTODOS: A genotipagem da haptoglobina foi realizada por reações em cadeia da polimerase alelo-específicas. As frequências dos genótipos de haptoglobina foram comparadas com a presença/ausência de doença cardiovascular, hipertensão arterial sistêmica, hipertensão refratária, obesidade e dislipidemia; medições de pressão arterial sistólica e diastólica; glicemia, colesterol (total, lipoproteínas de alta densidade - HDL e lipoproteínas de baixa densidade - LDL e triglicerídeos; assim como níveis de creatinina sérica. RESULTADOS: Embora nenhuma associação entre o genótipo de haptoglobina e a presença de doença cardiovascular tenha sido identificada, encontramos um excesso significativo de pacientes com o genótipo Hp2-1 entre as pessoas com hipertensão refratária, que também apresentavam uma maior pressão arterial sistólica e diastólica e níveis de colesterol total e LDL. CONCLUSÃO: Nossos resultados sugerem que os pacientes com diabete melito tipo 2 com o genótipo Hp2-1 podem apresentar uma maior chance de desenvolver hipertensão refratária. Estudos adicionais em populações diabéticas são necessários para confirmar esses achados.

  17. [Three-month rehabilitation of a patient with the III, IV and VI cranial nerve damage caused by a neurosurgery of the left internal carotid artery aneurysm].

    Mosiński, Eliasz; Kikowski, Łukasz; Irzmański, Robert

    Introduction: Oculomotor nerve palsy is an eye condition resulting from damage to the third cranial nerve or a branch thereof. Third nerve damage weakens the muscles innervated by the nerve . Also adversely affect the fourth and sixth nerve , causing impairment of their activity. Rehabilitation third nerve palsy is rarely described in the available literature . The whole process is very difficult , but the effects of physiotherapy is very beneficial for the patient. The aim:The assessment of the influence of the outpatient rehabilitation on the patient's condition after a three-month treatment and the use of physical therapy. Material and methods:Case studies of the 38-yerar-old patient after having operated a big aneurism of the left ICA, which was clipped. After the procedure, the III, IV and VI cranial nerves were deeply impaired and the amnesic aphasia occurred. The patient started the rehabilitation a month after the incident. To assess the process of rehabilitation, the own movement examination of the eyeball was implemented. Active and passive exercises, Tigger Point therapy, kinesiotaping, laser and electrostimulation were inserted. Results: The significant improvement of the eyeball movement has been proved on the basis of the same own examination. A physiotherapy has had a positive influence on the speech disorder, namely amnesic aphasia, and after the month of the rehabilitation it has been completely removed. The positive influence of the rehabilitation, which has been pointed out, is clinically essential. Conclusions: Obtained results have not been described in literature yet, that is why it is essential to widen further research and emphasise the importance of the rehabilitation, which is rarely implemented in an intense way in such medical conditions.

    Full Text Available RESUMOObjetivou-se com este trabalho verificar a divergência genética entre sete genótipos de frangos tipo caipira da linhagem Redbro utilizando as características de desempenho por meio de técnicas de análise multivariada. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. Após a consistência dos dados, foram avaliadas as seguintes variáveis: ganho em peso médio diário, consumo de ração médio diário e conversão alimentar, para os períodos: 1 a 28, 1 a 56, 1 a 70 e 1 a 84 dias de idade; peso corporal ao nascimento, aos 28, 56, 70 e aos 84 dias de idade. O desempenho dos genótipos foi avaliado por meio da análise de variância multivariada e da função discriminante linear de Fisher, usando os testes do maior autovalor de Roy e da união-interseção de Roy para as comparações múltiplas. O estudo da divergência genética foi feito por meio da análise por variáveis canônicas e pelo método de otimização de Tocher. Os genótipos Caboclo e Gigante Negro apresentaram médias canônicas diferentes dos demais genótipos. As duas primeiras variáveis canônicas explicaram 97,41% da variação entre os genótipos. A divergência genética entre os genótipos avaliados permitiu a formação de quatro grupos com os seguintes genótipos: grupo 1 - Colorpak; grupo 2 - Pesadão Vermelho e Pescoço Pelado; grupo 3 - Carijó e Tricolor; e grupo 4 - Caboclo e Gigante Negro.

  7. Arterial stiffness

    Ursula Quinn

    2012-09-01

    Full Text Available Measurements of biomechanical properties of arteries have become an important surrogate outcome used in epidemiological and interventional cardiovascular research. Structural and functional differences of vessels in the arterial tree result in a dampening of pulsatility and smoothing of blood flow as it progresses to capillary level. A loss of arterial elastic properties results a range of linked pathophysiological changes within the circulation including increased pulse pressure, left ventricular hypertrophy, subendocardial ischaemia, vessel endothelial dysfunction and cardiac fibrosis. With increased arterial stiffness, the microvasculature of brain and kidneys are exposed to wider pressure fluctuations and may lead to increased risk of stroke and renal failure. Stiffening of the aorta, as measured by the gold-standard technique of aortic Pulse Wave Velocity (aPWV, is independently associated with adverse cardiovascular outcomes across many different patient groups and in the general population. Therefore, use of aPWV has been proposed for early detection of vascular damage and individual cardiovascular risk evaluation and it seems certain that measurement of arterial stiffness will become increasingly important in future clinical care. In this review we will consider some of the pathophysiological processes that result from arterial stiffening, how it is measured and factors that may drive it as well as potential avenues for therapy. In the face of an ageing population where mortality from atheromatous cardiovascular disease is falling, pathology associated with arterial stiffening will assume ever greater importance. Therefore, understanding these concepts for all clinicians involved in care of patients with cardiovascular disease will become vital.

    Advanced pancreatic cancer has a poor prognosis, and the current standard of care (gemcitabine based chemotherapy) provides a small survival advantage. However the drawback is the accompanying systemic toxicity, which targeted treatments may overcome. This study aimed to evaluate the safety and tolerability of KAb201, an anti-carcinoembryonic antigen monoclonal antibody, labelled with I 131 in pancreatic cancer (ISRCTN 16857581). Patients with histological/cytological proven inoperable adenocarcinoma of the head of pancreas were randomised to receive KAb 201 via either the intra-arterial or intravenous delivery route. The dose limiting toxicities within each group were determined. Patients were assessed for safety and efficacy and followed up until death. Between February 2003 and July 2005, 25 patients were enrolled. Nineteen patients were randomised, 9 to the intravenous and 10 to the intra-arterial arms. In the intra-arterial arm, dose limiting toxicity was seen in 2/6 (33%) patients at 50 mCi whereas in the intravenous arm, dose limiting toxicity was noted in 1/6 patients at 50 mCi, but did not occur at 75 mCi (0/3). The overall response rate was 6% (1/18). Median overall survival was 5.2 months (95% confidence interval = 3.3 to 9 months), with no significant difference between the intravenous and intra-arterial arms (log rank test p = 0.79). One patient was still alive at the time of this analysis. Dose limiting toxicity for KAb201 with I 131 by the intra-arterial route was 50 mCi, while dose limiting toxicity was not reached in the intravenous arm

    Full Text Available Brachial artery (BA is a continuation of the axillary artery at the lower border of teres major. In the cubital fossa, BA divides into radial artery and ulnar artery as terminal branches. Large branch given from the BA in the upper part is profunda brachii artery. In the present case, we noticed double profunda brachii that arises from the BA. They are profunda brachii artery 1 and profunda brachii artery 2. Profunda brachii artery 1 arises in the proximal part of the BA and profunda brachii artery 2 arises distal to the profunda brachii artery 1. Both the arteries run inferolaterally in the spiral groove along with radial nerve. Variations of profunda brachii artery are important during harvesting of the lateral arm flaps and may lead to inadvertent injury during percutaneous arterial catheterization or injection of drugs.

    To categorize the anatomic variants of uterine arteries, and determine the incidence of menopausal symptoms where the tubo-ovarian branches were seen prior to embolization. Between July 1997 and June 2000, 257 (n = 257) uterine fibroid embolizations were performed at our institution. Arteriograms were retrospectively evaluated. Uterine arteries were classified into groups: type I (the uterine artery as first branch of the inferior gluteal artery), type II (the uterine artery as second or third branch of the inferior gluteal artery), type III (the uterine artery, the inferior gluteal and the superior gluteal arteries arising as a trifurcation), type IV (the uterine artery as first branch of the hypogastric artery), inconclusive, or not studied. Tubo-ovarian branches were recorded if visualized prior to and/or after embolization. Menopausal symptoms were recorded (n = 175 at 3 months, n = 139 at 6 months, n = 98 at 1 year, n = 22 at 2 years) using written questionnaires. Five hundred and fourteen uterine arteries (n = 514) were evaluated. There were 38% classifiable types, 23% inconclusive, and 39% not studied. Classification was as follows: type I, 45%; type II, 6%; type III, 43%; type IV, 6%. Among 256 patients, tubo-ovarian arteries were seen in 36 prior to embolization, but not afterwards. In this group, 25 patients reported transient menopausal symptoms (hot flashes, amenorrhea). Five patients did not report any menopausal symptoms. Six patients did not answer the questionnaires. Type I is the most common type of anatomy, followed by type III. The tubo-ovarian arteries may be visualized prior to and/or after embolization. The embolization was monitored to avoid embolization of the tubo-ovarian branches. Menopausal symptoms were transient all patients when the tubo-ovarian branches were seen prior to embolization

En los ensayos de laboratorio y a escala natural, las variedades comerciales de estas resinas, conocidas con los nombres de «neopreno» y «Teflon», han sido elegidas por presentar, por lo menos actualmente, características marcadamente apropiadas a la finalidad perseguida en este estudio, del que se confía ulterior desarrollo y mejor acogida, por las importantes aplicaciones que de él se derivan en el campo de la ingeniería y construcción. Los autores estudian con detenimiento y sobrado rigor para las aplicaciones prácticas las deformaciones que de estos materiales se espera al someterlos a fuerzas de gran concentración. En los apoyos juega particular interés la distribución de la carga siempre concentrada en superficies relativamente pequeñas, lo que exige elevadas cargas unitarias y, con ello, la utilización de materiales extremadamente nobles para resistirlas con la resistencia que las deformaciones instantáneas requieren para recobrar rápidamente la posición de estabilidad perdida momentáneamente. La fatiga en el ciclo de deformaciones relaja los materiales, y ha de tenerse presente al considerar las características que los

    Brachial artery (BA) is a continuation of the axillary artery at the lower border of teres major. In the cubital fossa, BA divides into radial artery and ulnar artery as terminal branches. Large branch given from the BA in the upper part is profunda brachii artery. In the present case, we noticed double profunda brachii that arises from the BA. They are profunda brachii artery 1 and profunda brachii artery 2. Profunda brachii artery 1 arises in the proximal part of the BA and profunda brachii...

    Complex internal carotid artery disease presents a surgical challenge because limitations and difficulty are encountered with either clipping or endovascular treatment. Our review of previous reports suggests that no current vascular assessment can accurately predict occurrence of ischemic complications after internal carotid artery ligation. The present study concerns long-term clinical outcome of radial artery grafting followed by parent artery trapping or proximal occlusion for management of these difficult lesions. Between September 1997 and October 2007, we performed radial artery grafting followed immediately by parent artery occlusion in 20 sides of 19 patients with complex internal carotid arteries disease with follow-up for more than 36 months (5 men, 14 women; mean follow-up duration, 62 months). All patients underwent postoperative MRI and MR angiography (MRA) every year to assess graft patency, ischemic complications, and de novo aneurysm. Another 20 carotid aneurysms with visual disturbance were assessed concerning outcome. Among 13 patients with cranial nerve (III and VI) disturbances, all dysfunctions were improved in cases treated within 8 months of onset to operation. On the other hand, patients with second cranial nerve disturbances were not improved in cases treated after 4 months of onset. No long-term complications were discovered with MRI and MRA. With appropriate attention to surgical technique, radial artery grafting followed by acute parent artery occlusion is a safe treatment for complex internal carotid artery aneurysms. Long-term safety is satisfactory, with no delayed complications such as graft stenosis, ischemic complications or de novo aneurysm formations in follow-up periods of more than 3 years. Good clinical outcome of cranial nerve palsy was achieved in patients treated within 8 months of onset for cranial nerve (CN) III and VI, and 4 of CN II palsy. (author)

    Objective: To demonstrate the safety and feasibility of the transpedal approach as an alternate arterial access site for iliac artery intervention. Background: The common femoral artery is the traditional access site for the endovascular treatment of iliac artery stenoses. However, this approach is associated with complication rates as high as 2%, including retroperitoneal bleeding which carries high patient morbidity and mortality. Furthermore, the standard femoral approach is associated with longer recovery times and longer time to ambulation which are important considerations especially when performing procedures in an ambulatory setting. Methods: Twelve patients were prospectively followed after treatment for symptomatic iliac artery stenosis via transpedal access. Under ultrasound guidance, one of the pedal arteries was visualized and accessed, and stenting of the iliac arteries were performed as per protocol. The patient was monitored immediately post procedure and clinical follow up was performed at one week and one month later. Results: The average age of the patients was 71 years old. 58% were male. Most patients had Rutherford class III symptoms. Successful stent placement was achieved in all 12 patients via transpedal access. No conversion to femoral access was required. No complications immediately post procedure nor at any time period during follow up were noted. Lower extremity arterial duplex at one month showed patent stents and patent pedal access site vessels in all patients. Conclusion: Transpedal arterial access may be a safe and feasible approach for iliac artery stenting. Given the possible benefits of avoiding femoral artery access, larger studies should be conducted directly comparing the different approaches.

    2009-01-01

    Objective: To investigate the variations of hepatic artery and its extrahepatic arteries on hepatic arteriogram and to provide benefit for transhepatic arterical chemoemblization. Methods: The hepatic arteriograms of 200 cases with unresectable hepatic malignant tumor before interventional therapy were analysed. Two interventional radiologists in common reviewed the incidences of various types according to Michels' classification, the absence of proper hepatic artery, and the variations of extrahepatic arteries originating from hepatic artery. Results: The most common hepatic artery variation was Michels type III(n=17,8.5%), followed by type II(n=10,5.0%) and V(n=9,4.5%). Proper hepatic absence was found in 25 cases and appeared as 5 subtypes. 5 kinds of extrahepatic arteries were found. The most common extrahepatic artery was the right gastric artery (n=156,78.0%), followed by cystic artery (n=126,63.0%), accessory left gastric artery (n=19,9.5%), the hepatic falciform artery (n=5,2.5%), and accessory left inferior phrenic artery (n=4,2.0%). Conclusion: There are some other variations of hepatic artery beside Michels' classification,and there are many variations of extrahepatic arteries originating from hepatic artery, it is important to assure interventional therapy effect for hepatic cancer and prevent complication.

    The study included 1172 patients (410 men and 762 women) at the mean age of 60.3 ± 10.4 years with grade I-II (stage I-II) arterial hypertension (AH) admitted to the clinic of Institute of Experimental Medicine. The patients were divided into 2 groups based on the results of clinical and laboratory diagnostics. Group 1 (n = 525) included patients with AH and hepatobiliary system (HBS) diseases, group 2 (n = 647) patients with AH without HBS diseases. The patients group 1 had a thicker intima-media complex of carotid arteries, higher peak systolic bloodflow rate in the internal and vertebral carotid arteries, more pronounced coiling of internal carotid arteries than patients of group 2. Patients with AH and HBS diseases exhibited correlation between bloodflow rate in external carotid arteries and atherogenicity coefficient. Duplex scanning of neck vessels of in patients with AH without HBS diseases revealed peculiar changes of the intima-media thickness and hemodynamically significant changes of the blood flow in the internal carotid arteries that may be of prognostic value in this nosological syntropy and require the personified approach to diagnostics, treatment, and prevention of these conditions.

    2007-01-01

    Complex giant or large internal carotid artery aneurysms present a surgical challenge because limitations and difficulty are encountered with either clipping or endovascular treatment. Our review of previous reports suggests that no current vascular assessment can accurately predict the occurrence of ischemic complications after internal carotid artery ligation. The present study concerns surgical technique, complications, and clinical outcome of radial artery grafting followed by parent artery trapping or proximal occlusion for management of these difficult lesions. Between September 1997 and October 2005, we performed radial artery grafting followed immediately by parent artery occlusion in 17 patients with giant or large complex intracranial carotid aneurysms (3 men, 14 women; mean follow-up duration, 62 months). All patients underwent postoperative digital subtraction angiography to assess graft patency and aneurysm obliteration. All 17 aneurysms were excluded from the cerebral circulation, with all radial artery grafts patent. Among 4 patients with cranial nerve disturbances, dysfunction was temporary in 5; in the others, oculomotor nerve paresis persisted. No perioperative cerebral infarction occurred. Sensory aphasia reflecting cerebral contusions caused by temporal lobe retraction resolved within 2 months, as did hemiparesis from a postoperative epidural hematoma. With appropriate attention to surgical technique, radial artery grafting followed by acute parent artery occlusion is a safe treatment for complex internal carotid artery aneurysms. Graft patency and aneurysm thrombosis were achieved in all patients. Cranial nerve dysfunction (III, VI) caused by altered blood flow from the internal carotid artery after occlusion was the most common complication and typically was temporary. In our experience with these difficult aneurysms, not only clipping but also reconstruction of the internal carotid artery was required, especially for wide-necked symptomatic

  6. Jet pump assisted artery

    1975-01-01

    A procedure for priming an arterial heat pump is reported; the procedure also has a means for maintaining the pump in a primed state. This concept utilizes a capillary driven jet pump to create the necessary suction to fill the artery. Basically, the jet pump consists of a venturi or nozzle-diffuser type constriction in the vapor passage. The throat of this venturi is connected to the artery. Thus vapor, gas, liquid, or a combination of the above is pumped continuously out of the artery. As a result, the artery is always filled with liquid and an adequate supply of working fluid is provided to the evaporator of the heat pipe.

O objetivo do trabalho foi caracterizar frutos em pós-colheita, identificar a preferência e a intenção de compra de diferentes genótipos de bananeira tipo Prata. Os genótipos Prata-Anã, BRS Platina e Fhia-18. foram caracterizados no ponto de colheita (verdes e maduros (estádio seis de maturação, por avaliações químicas, físicas e sensoriais. Quando verde, ‘BRS Platina’ apresentou maior massa fresca e tamanho que ‘Fhia-18’ e ‘Prata-Anã’. ‘Fhia-18.’ teve a tonalidade verde da casca mais intensa que a dos demais genótipos. Madura, ‘BRS Platina’ foi mais firme, mas com a mesma resistência ao despencamento que ‘Fhia-18’ e superior à ‘Prata-Anã’. ‘Fhia-18’ apresentou cor da casca com amarelo mais clara e tão brilhante quanto da ‘Prata-Anã’, mas ‘BRS Platina’ teve a tonalidade de amarelo mais intensa. Bananas ‘Fhia-18’ foram mais ácidas, ‘BRS Platina’, com menor acidez titulável, e ‘Prata-Anã’, o maior teor de sólidos solúveis. Os genótipos Prata-Anã e BRS Platina tiveram maior preferência e intenção de compra pelos consumidores, sendo as bananas ‘Prata-Anã’ em dedos e ‘BRS Platina’ e ‘Fhia-18’ em dedos, buquê e penca, as mais preferidas. Entretanto, a maioria compraria bananas ‘Prata-Anã’ em buquê e ‘BRS Platina’ e ‘Fhia-18’ em penca. Enquanto verdes, os genótipos foram semelhantes à ‘Prata-Anã’, e maiores diferenças químicas e físicas ocorreram quando maduros.

Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. Os frangos foram alojados em 28 boxes, sendo 30 frangos por boxe, em galpão de alvenaria com acesso a um piquete de 45m², em quatro repetições. As características de desempenho (conversão alimentar, ganho em peso médio diário, consumo de ração médio diário foram avaliadas nos períodos: um a 28, um a 56, um a 70 e um a 84 dias de idade. O peso corporal foi avaliado aos 28, 56, 70 e 84 dias de idade. As características de carcaça (peso e rendimento de carcaça, peito e pernas foram obtidas a partir do abate de dois frangos por boxe, aos 85 dias de idade. As análises estatísticas foram realizadas utilizando-se o "proc glm" do SAS. Verificou-se que, em todos os períodos, os frangos do genótipo Colorpak apresentaram maior peso corporal, consumo de ração médio diário, ganho em peso médio diário e melhor conversão alimentar. Entretanto, os genótipos Caboclo e Gigante Negro apresentaram menores consumo de ração médio diário, ganho de peso médio diário e pior conversão alimentar. Quanto ao rendimento de cortes, observou-se que os genótipos Caboclo e Gigante Negro apresentaram os menores valores, e o Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor obtiveram os melhores rendimentos de pernas. Para o rendimento de peito, o Carijó e o Pesadão Vermelho obtiveram os maiores valores. A escolha do genótipo deve ser feita de acordo com o interesse do mercado, pois há diferenças no desempenho e no rendimento de carcaça e dos cortes.

    Full Text Available A síndrome do aprisionamento da artéria poplítea caracteriza-se pela compressão desta artéria sendo a principal causa de claudicação intermitente em jovens. Homem, 18 anos, branco, apresentava parestesia, frialdade e palidez do pé direito, iniciada 24 horas após exercício físico. Em membro inferior direito, ausência de pulsos tibial posterior e dorsal do pé. À flexão dorsal e flexão plantar forçadas, houve diminuição dos pulsos tibial posterior e dorsal do pé à esquerda. Tratado cirurgicamente, o paciente apresentou pulso em ambas as artérias. A síndrome é mais frequente em homens e a prevalência varia entre 0,16 e 3,5%. O aprisionamento da artéria poplítea tipo III é mais comum. A falta de tratamento pode levar à embolia, trombose e aneurismas pós-estenóticos. Esta síndrome deve ser lembrada como causa de dor na perna, especialmente em homens jovens e de prática esportiva intensa.Popliteal artery entrapment syndrome is the compression of the popliteal artery and is the main cause of intermittent claudication in young patients. An 18-year-old man was admitted at our service complaining of right foot paresthesia, coldness, and pallor that appeared 24 hours after physical activity. Posterior tibial and dorsal artery of foot pulses were not present in right lower limb. Diminished posterior tibial and dorsal artery of the foot pulses were found in left lower limb at dorsal flexion and forced plantar flexion. After surgery, both pulses were present. This syndrome is more frequent in men and its prevalence varies between 0.16 and 3.5%. Popliteal artery entrapment type III is most common. Non-treated entrapment can lead to embolism, thrombosis and post-stenotic aneurysms. The syndrome must be considered as a cause of lower limb pain specially in young men with intense sport practice history.

  15. Duplicated middle cerebral artery

    Perez, Jesus; Machado, Calixto; Scherle, Claudio; Hierro, Daniel

    2009-01-01

    Duplicated middle cerebral artery (DMCA) is an anomalous vessel arising from the internal carotid artery. The incidence DMCA is relatively law, and an association between this anomaly and cerebral aneurysms has been documented. There is a controversy whether DMCA may have perforating arteries. This is an important fact to consider in aneurysm surgery. We report the case of a 34-year-old black woman who suffered a subarachnoid hemorrhage and the angiography a left DMCA, and an aneurysm in an inferior branch of the main MCA. The DMCA and the MCA had perforating arteries. The aneurysm was clipped without complications. The observation of perforating arteries in our patient confirms that the DMCA may have perforating arteries. This is very important to be considered in cerebral aneurysms surgery. Moreover, the DMCA may potentially serve as a collateral blood supply to the MCA territory in cases of MCA occlusion. PMID:22140405

    Renovascular hypertension is a common cause of pediatric hypertension. In the fraction of cases that are unrelated to syndromes such as neurofibromatosis, patients with a solitary stenosis on a branch of the renal artery are common and can be diagnostically challenging. Imaging techniques...... that perform well in the diagnosis of main renal artery stenosis may fall short when it comes to branch artery stenosis. We report 2 cases that illustrate these difficulties and show that a branch artery stenosis may be overlooked even by the gold standard method, renal angiography....

    1986-01-01

    Congenital coronary artery fistula (CCAF) is communication of a coronary artery or its main branch with one of the atria or ventricles, the coronary sinus, the superior vena cava, or the pulmonary artery. In Korean peoples, only 4 cases of the CCAF were reported as rare as worldwide and authors want to report another case of CCAF, confirmed by operation. 10-year-old girl shows a fistula between sinus node artery of the right coronary artery and right atrium on root aortogram with left-to-right shunt and Qp/Qs=1.58, in which simple ligation of the sinus node artery from right coronary artery was performed. All of the 5 Korean CCAF (4 were previously reported and 1 of authors) were originated from right coronary artery, and of which 4 were opening into right ventricle and 1 of authors were into right atrium. Associated cardiac anomaly was noted in only 1 case as single coronary artery. Ages were from 9 months of age to 10 years old and no adult left case were found. 3 were female and 2 were male patients.

  3. Hepatic artery infusion (HAI) for hepatic metastases in combination with hepatic resection and hepatic radiation

    Merrick, H.W.; Dobelbower, R.R.; Ringleint, J.F.; Skeel, R.T.

    1986-01-01

    Renewed interest in hepatic artery infusion has been stimulated by the development of a totally implantable pump which eliminates many of the problems encountered by the external pumps and catheters. As the potential benefit of hepatic artery infusion would be greater if either all gross disease were removed by prior resection, or alternatively, if non-resectable disease were irradiated in conjunction with hepatic artery infusion, the authors initiated a phase I-II trial to evaluate combined modality therapy

  7. Pressure drop and arterial compliance - Two arterial parameters in one measurement.

    Rotman, Oren M; Zaretsky, Uri; Shitzer, Avraham; Einav, Shmuel

    2017-01-04

    Coronary artery pressure-drop and distensibility (compliance) are two major, seemingly unrelated, parameters in the cardiovascular clinical setting, which are indicative of coronary arteries patency and atherosclerosis severity. While pressure drop is related to flow, and therefore serves as a functional indicator of a stenosis severity, the arterial distensibility is indicative of the arterial stiffness, and hence the arterial wall composition. In the present study, we hypothesized that local pressure drops are dependent on the arterial distensibility, and hence can provide information on both indices. The clinical significance is that a single measurement of pressure drop could potentially provide both functional and bio-mechanical metrics of lesions, and thus assist in real-time decision making prior to stenting. The goal of the current study was to set the basis for understanding this relationship, and define the accuracy and sensitivity required from the pressure measurement system. The investigation was performed using numerical fluid-structure interaction (FSI) simulations, validated experimentally using our high accuracy differential pressure measurement system. Simplified silicone mock coronary arteries with zero to intermediate size stenoses were used, and various combinations of arterial distensibility, diameter, and flow rate were simulated. Results of hyperemic flow cases were also compared to fractional flow reserve (FFR). The results indicate the potential clinical superiority of a high accuracy pressure drop-based parameter over FFR, by: (i) being more lesion-specific, (ii) the possibility to circumvent the FFR dependency on pharmacologically-induced hyperemia, and, (iii) by providing both functional and biomechanical lesion-specific information.

  16. Occlusion of Heubner's artery

    Sato, Manabu; Kidooka, Minoru

    1982-01-01

    A case of occlusion of the left Heubner's artery in a right-handed, 51-year-old man is reported. Cardinal clinical features were transient right hemiparesis and mental disturbance, especially intellectual defect. Low density areas were found at CT in the globus pallidus, putamen, anterior limb of the internal capsule and a part of the caudate nucleus. It is well known that the occlusion of the Heubner's artery causes transient motor paresis of upper extremity on the contralaterl side. However, in the case where the Heubner's artery is remarkably well developed when compared with the medial striate arteries as was the case in this patient, it should be noted that the occlusion of the Heubner's artery may well causes grave mental disturbance, in addition.

  2. Propiedades y aplicaciones de piezocomposites tipo címbalo

    Ochoa, P.

    2001-08-01

    Full Text Available The metal-ceramic composite actuators, moonies and cymbals consist in capped piezoceramic disks with metallic endcaps having cavities inside. These cavities favour the amplification of direct and reverse piezoelectric effects. These actuators fill the gap between high displacement low generative force bimorph actuators and low displacement high generative force multilayer ceramic actuators. The moonie actuator can give displacements greater than 100 mm, maximum generative force of 3N to several N´s, response time of 20 to 100 ms, and low fatigue test response for more than 107 cycles. Cymbals actuators shows twice as big as displacement than moonie for the studied size, much higher generative force and the possibility to avoid the temperature dependence of the displacement for selected materials. Properties of cymbal actuators can be tailored trough the selection of materials. Also, cymbal actuators can be tuned to adopt different resonance frequencies.

    Los composites metal-cerámica tipo luna y címbalo consisten en discos piezoeléctricos encapsulados con cápsulas metálicas que poseen una cavidad. Esta cavidad favorece la amplificación de los efectos piezoeléctricos directo e inverso. Estos actuadores llenan el escalón entre actuadores multicapa, con desplazamientos pequeños y fuerzas generativas elevadas, y actuadores bimorfos, con desplazamientos grandes y fuerzas generativas pequeñas. El actuador tipo luna alcanza desplazamientos de más de 100mm, fuerzas generativas máximas de hasta varios N´s, tiempos de respuesta desde 20 hasta 100ms, y baja respuesta en ensayos de fatiga a más de 107 ciclos. Los actuadores tipo címbalo muestran desplazamientos dos veces mayores que los obtenidos con actuadores tipo luna para el mismo tamaño, fuerzas generativas mucho mayores y la posibilidad de eliminar la dependencia del desplazamiento con la temperatura mediante selección de los materiales.

    Full Text Available La hipertensión arterial (HTA dependiente de mineralocorticoides representa actualmente una de las formas secundarias de hipertensión más prevalentes. Entre las causas más conocidas está el hiperaldosteronismo primario (HAP. A nivel renal, la aldosterona reabsorbe sodio y agua aumentando el volumen intravascular y la presión arterial. Actualmente la prevalencia de HAP, detectada por la razón aldosterona/actividad renina plasmática (ARR que es considerado el mejor test de screening, es cercana al 10% en población hipertensa. Por otra parte, defectos congénitos o adquiridos en la enzima 11β-Hidroxiesteroide deshidrogenasa tipo 2 (11β-HSD2 resultan en una ineficiente inactivación de cortisol a cortisona favoreciendo la aparición de hipertensión por activación del receptor mineralocorticoideo. La actividad de esta enzima se evalúa midiendo la razón cortisol/cortisona en suero o en orina de 24 horas. Recientemente, hemos observado déficit parciales de la actividad de la enzima 11β-HSD-2 en alrededor del 15% de los pacientes hipertensos esenciales los que podrían ser tratados con bloqueadores específicos del receptor mineralocorticoide y/o con corticoides de acción prolongada sin actividad mineralocorticoide como dexametasona o betametasona.

    Renal artery disease is a potentially correctable cause of hypertension. Previous studies have suggested the utility of duplex sonography in accurately detecting and grading the severity of renal artery stenosis. The purpose of this paper is to evaluate color flow Doppler for this use. Forty-three kidneys were examined by color-flow Doppler and conventional duplex sampling in patients with suspected renovascular hypertension or those undergoing aortography for unrelated reasons. Doppler tracings were obtained from the renal arteries and aorta with calculation of the renal aortic ratio (RAR) and resistive index (RI). Results of Doppler sampling with color flow guidance were compared with aortograms in a blinded fashion

  8. Coronary artery aneurysms

    Koischwitz, D.; Harder, T.; Schuppan, U.; Thurn, P.

    1982-04-01

    Seven saccular coronary artery aneurysms have been demonstrated in the course of 1452 selective coronary artery angiograms. In six patients they were arterio-sclerotic; in one patient the aneurysm must have been congenital or of mycotic-embolic origin. The differential diagnosis between true aneurysms and other causes of vascular dilatation is discussed. Coronary artery aneurysms have a poor prognosis because of the possibility of rupture with resultant cardiac tamponade, or the development of thrombo-embolic myocardial infarction. These aneurysms can only be diagnosed by means of coronary angiography and require appropriate treatment.

  9. Vertebrobasilar Artery Occlusion

    Schoen, Jessica

    2011-05-01

    Full Text Available The presentation of vertebrobasilar artery occlusion varies with the cause of occlusion and location of ischemia. This often results in delay in diagnosis. Areas of the brain supplied by the posterior circulation are difficult to visualize and usually require angiography or magnetic resonance imaging. Intravenous thrombolysis and local-intra arterial thrombolysis are the most common treatment approaches used. Recanalization of the occluded vessel significantly improves morbidity and mortality. Here we present a review of the literature and a case of a patient with altered mental status caused by vertebrobasilar artery occlusion. [West J Emerg Med. 2011;12(2:233-239.

    The authors analyze 50 patients with endarterectomy of the coronary arteries during the periods of 1972-1974 and 1988-1990. The results of endarterectomy of the right and left coronary artery provide evidence of its justification in indicated cases whereby contrary to some departments the results of endarterectomy of the left coronary artery are comparable with endarterectomy of the right coronary artery.

  11. Effect of hypothermic pulmonary artery flushing on capillary filtration coefficient.

    Andrade, R S; Wangensteen, O D; Jo, J K; Tsai, M Y; Bolman, R M

    2000-07-27

    We previously demonstrated that surfactant dilution and inhibition occur immediately after pulmonary artery flushing with hypothermic modified Euro-Collins solution. Consequently, we speculated that increased capillary permeability contributed to these surfactant changes. To test this hypothesis, we evaluated the effects of hypothermic pulmonary artery flushing on the pulmonary capillary filtration coefficient (Kfc), and additionally performed a biochemical analysis of surfactant. We used a murine isolated, perfused lung model to measure the pulmonary capillary filtration coefficient and hemodynamic parameters, to determine the wet to dry weight ratio, and to evaluate surfactant by biochemical analysis of lung lavage fluid. We defined three study groups. In group I (controls), we harvested lungs without hypothermic pulmonary artery flushing, and measured Kfc immediately. In group II (in situ flush), we harvested lungs after hypothermic pulmonary artery flushing with modified Euro-Collins solution, and then measured Kfc. Experiments in groups I and II were designed to evaluate persistent changes in Kfc after pulmonary artery flushing. In group III (ex vivo flush), we flushed lungs ex vivo to evaluate transient changes in Kfc during hypothermic pulmonary artery flushing. Groups I and II did not differ significantly in capillary filtration coefficient and hemodynamics. Group II showed significant alterations on biochemical surfactant analysis and a significant increase in wet-to-dry weight ratio, when compared with group I. In group III, we observed a significant transient increase in capillary filtration coefficient during pulmonary artery flushing. Hypothermic pulmonary artery flushing transiently increases the capillary filtration coefficient, leads to an increase in the wet to dry weight ratio, and induces biochemical surfactant changes. These findings could be explained by the effects of hypothermic modified Euro-Collins solution on pulmonary capillary

  12. Fingertip amputation salvage on arterial anastomosis alone: an investigation of its limitations.

    Ito, Hiroshi; Sasaki, Kenji; Morioka, Kousuke; Nozaki, Motohiro

    2010-09-01

    We have previously reported the importance of adequate and precise arterial anastomosis and the hypothesis that, up to subzone III, fingertip amputation salvage can be achieved on arterial anastomosis alone. These findings were reported during the meeting of the Japanese Society of Reconstructive Microsurgery. This is our follow-up report with insight and opinion on the limitations of complete fingertip amputation salvage on arterial anastomosis alone. We examined 67 fingers (59 patients) with fingertip amputations presenting to our hospital between January 2005 and December 2008. Amputation levels and whether these injuries received only arterial or both arterial and venous anastomoses were noted. Fisher exact test was used to examine statistical differences between the groups. Amputation levels were 11 in subzone I, 20 in subzone II, 17 in subzone III, and 19 in subzone IV. Successful replantation was achieved in 87% (58 of 67) of fingers. There was no statistically significant difference between fingers receiving arterial alone versus both anastomoses in amputations of subzones I, II, and III. We found that with proper postoperative congestion care, no statistically significant difference in replantation success of fingers receiving arterial anastomosis alone versus both arterial and venous were noted up to subzone III. However, in subzone IV, regardless of the postoperative congestion, compete necrosis rates are high; thus, it is speculated that a venous anastomosis is necessary for successful replantation. It is preferable to perform as many anastomoses as possible, but we believe that it is also desirable for the procedure to be fast and less invasive. In cases that have no adequate vein, fingertip replantation can be achieved on arterial anastomosis alone up to subzone III.

    2012-10-01

    Full Text Available La nefropatía constituye la complicación más grave de la diabetes mellitus tipo 1 (DMt1 siendo una de las manifestaciones iniciales la microalbuminuria. Objetivos: Determinar el comportamiento de los factores epidemiológicos, clínicos y bioquímicos en el desarrollo de microalbuminuria en pacientes con DMt1. Diseño: Estudio de casos y controles. Lugar: Servicio de Endocrinología del Instituto Nacional de Salud del Niño, Lima, Perú. Participantes: Pacientes diabéticos tipo 1 menores de 18 años. Intervenciones: Se estudió 64 pacientes portadores de DMt1, 22 con microalbuminuria y 42 sin esta manifestación, que constituyeron los casos y controles respectivamente. Se consignó como factores epidemiológicos la edad al diagnóstico, tiempo de evolución, género, antecedentes familiares de diabetes, nefropatía, dislipidemia, hipertensión arterial; como factores clínicos, el estado nutricional, desarrollo puberal (Tanner, presión arterial; y como factores bioquímicos, la hemoglobina glicosilada (HbA1c, microalbuminuria y perfil lipídico. Tanto los casos como los controles fueron seguidos durante un año. El análisis estadístico se hizo mediante pruebas de chi cuadrado, odds ratio y regresión logística, para establecer predominancia de factores. Principales medidas de resultados: Estadio puberal, perfil lipídico y HbA1c. Resultados: Los factores de riesgo hallados fueron la presión arterial diastólica elevada (p=0,037, la pubertad (p=0,008, HbA1c alta (p< 0,0001, hipertrigliceridemia (p= 0,007 y la hipercolesterolemia (p< 0,0001. Conclusiones: La HbA1c elevada, la hipercolesterolemia y la pubertad fueron los factores de riesgo de mayor preponderancia para el desarrollo de microalbuminuria. A fin de prevenir el desarrollo de microalbuminuria, se sugiere buen control metabólico y cuidadoso manejo de la dislipidemia, en especial en pacientes púberes.

    Metallothionein-III is a low molecular weight, heavy-metal binding protein expressed mainly in the central nervous system. First identified as a growth inhibitory factor (GIF) of rat cortical neurons in vitro, it has subsequently been shown to be a member of the metallothionein (MT) gene family...... injected rats. The specificity of the antibody was also demonstrated in immunocytochemical studies by the elimination of the immunostaining by preincubation of the antibody with brain (but not liver) extracts, and by the results obtained in MT-III null mice. The antibody was used to characterize...... the putative differences between the rat brain MT isoforms, namely MT-I+II and MT-III, in the freeze lesion model of brain damage, and for developing an ELISA for MT-III suitable for brain samples. In the normal rat brain, MT-III was mostly present primarily in astrocytes. However, lectin staining indicated...

  17. Arterial ammonia levels in the management of fulminant liver failure

    Curry S

    2011-06-01

    Full Text Available Previous studies have suggested that an arterial ammonia level greater than 150 mmol/L is highly sensitive for predicting subsequent development of cerebral edema in patients with fulminant liver failure. We performed a prospective cohort study to confirm this relationship. We enrolled 22 consecutive patients who presented to our transplant hepatology service with grade 3-4 encephalopathy associated with fulminant liver failure. All patients underwent placement of an intraparenchymal ICP monitor, and every 12 hourly arterial ammonia levels. The prevalence of intracranial hypertension (IHTN in our population was 95% (21/22 patients, with 82 discrete episodes recorded. The sensitivity of arterial ammonia levels to predict the onset of IHTN was 62% (95% CI: 40.8 to 79.3 at a cut point of 150 mmol/L. Arterial ammonia levels preceding the first intracranial hypertension event were less than 150 mmol/L in 8 of 21 patients (39%. Fifty nine of 82 episodes of IHTN (73% occurred when arterial ammonia levels were less than 150 mmol/L. We conclude that the arterial ammonia level is not useful in making decisions regarding management related to cerebral edema in patients with fulminant liver failure. In fact, since almost all our study patients with grade III or IV encephalopathy secondary to fulminant liver failure went on to develop intracranial hypertension, our study supports the contention that all such patients might benefit from ICP monitoring regardless of arterial ammonia levels.

En ambos tipos de pitahayas, se realizaron autopolinizaciones y polinizaciones cruzadas directas y recíprocas, con el propósito de evaluar el efecto en la cantidad de frutos que lograron su desarrollo. Se midieron algunas variables para detectar la influencia del progenitor paterno en algunas características del fruto. Los testigos se obtuvieron de flores polinizadas libremente. El diseño experimental utilizado fue completamente al azar, con 15 repeticiones por tratamiento. Se encontró que Uqroo1 es autocompatible, mientras que Uqroo2 es autoincompatible. Los testigos de ambos tipos alcanzaron el mismo peso, y los frutos de Uqroo2 logrados por polinización cruzada tuvieron un peso similar al de los testigos o fueron significativamente mas pesados. Algunas variables resultaron positivamente correlacionados; el coeficiente entre el número de semillas y el peso total del fruto fue de r = 0.84. La correlación mas alta (r = 0.97 resultó entre el peso total y el peso de la pulpa. En los frutos obtenidos por polinización cruzada prevalecieron las características del progenitor materno.

    PurposeTo describe and categorize the angiographic findings regarding prostatic vascularization, propose an anatomic classification, and discuss its implications for the PAE procedure.MethodsAngiographic findings from 143 PAE procedures were reviewed retrospectively, and the origin of the inferior vesical artery (IVA) was classified into five subtypes as follows: type I: IVA originating from the anterior division of the internal iliac artery (IIA), from a common trunk with the superior vesical artery (SVA); type II: IVA originating from the anterior division of the IIA, inferior to the SVA origin; type III: IVA originating from the obturator artery; type IV: IVA originating from the internal pudendal artery; and type V: less common origins of the IVA. Incidences were calculated by percentage.ResultsTwo hundred eighty-six pelvic sides (n = 286) were analyzed, and 267 (93.3 %) were classified into I–IV types. Among them, the most common origin was type IV (n = 89, 31.1 %), followed by type I (n = 82, 28.7 %), type III (n = 54, 18.9 %), and type II (n = 42, 14.7 %). Type V anatomy was seen in 16 cases (5.6 %). Double vascularization, defined as two independent prostatic branches in one pelvic side, was seen in 23 cases (8.0 %).ConclusionsDespite the large number of possible anatomical variations of male pelvis, four main patterns corresponded to almost 95 % of the cases. Evaluation of anatomy in a systematic fashion, following a standard classification, will make PAE a faster, safer, and more effective procedure.

  14. Mechanical design in arteries.

    Shadwick, R E

    1999-12-01

    The most important mechanical property of the artery wall is its non-linear elasticity. Over the last century, this has been well-documented in vessels in many animals, from humans to lobsters. Arteries must be distensible to provide capacitance and pulse-smoothing in the circulation, but they must also be stable to inflation over a range of pressure. These mechanical requirements are met by strain-dependent increases in the elastic modulus of the vascular wall, manifest by a J-shaped stress-strain curve, as typically exhibited by other soft biological tissues. All vertebrates and invertebrates with closed circulatory systems have arteries with this non-linear behaviour, but specific tissue properties vary to give correct function for the physiological pressure range of each species. In all cases, the non-linear elasticity is a product of the parallel arrangement of rubbery and stiff connective tissue elements in the artery wall, and differences in composition and tissue architecture can account for the observed variations in mechanical properties. This phenomenon is most pronounced in large whales, in which very high compliance in the aortic arch and exceptionally low compliance in the descending aorta occur, and is correlated with specific modifications in the arterial structure.

    Full Text Available This paper is about a posttraumatic distal ulnar artery thrombosis case that has occurred after a single blunt trauma. The ulnar artery thrombosis because of chronic trauma is a frequent condition (hypothenar hammer syndrome but an ulnar artery thrombosis because of a single direct blunt trauma is rare. Our patient who has been affected by a single blunt trauma to his hand and developed ulnar artery thrombosis has been treated by resection of the thrombosed ulnar artery segment. This report shows that a single blunt trauma can cause distal ulnar artery thrombosis in the hand and it can be treated merely by thrombosed segment resection in suitable cases.

    2002-01-01

    Full Text Available En vista que las evidencias obtenidas acerca del beneticio percibido por los sujetos hipertensos leves con los tratamientos farmacológicos resultan conflictivas, se ha considerado importante para estos pacientes, la aplicación de intervenciones psicológicas y comportamentales. Se presentan en este trabajo, distintos tipos de tratamientos psicológicos que en los últimos años han demostrado su efectividad en la reducción de la presión arterial esencial. Se consideraron importantes para individuos hipertensos leves, la implementación de procedimientos tales como: la relajación, el entrenamiento autógeno, la retroalimentación biológica, la meditación, el Hatha -Yoga, la reestructuración cognitiva y el entrenamiento en habilidades sociales, porque contribuyeron a la reducción, no solo de los niveles hipertensivos sino también de los efectos adversos de la medicación farmacológica que afectan la calidad de vida. Es necesario evidentemente que el individuo generalice las estrategias aprendidas en el contexto clínico-experimental, a los diferentes contextos vitales. La técnica empleada, las características del terapeuta y el tipo de personalidad del paciente son componentes principales en la determinación del éxito del tratamiento. La práctica diaria sostenida fuera del contexto clínico, es un elemento de crucial importancia para el mantenimiento de la mejoría lograda.

    Full Text Available Percutaneous vascular embolization plays an important role in the management of various gynecologic and obstetric abnormalities. Transcatheter embolization is a minimally invasive alternative procedure to surgery with reduced morbidity and mortality, and preserves the patient's future fertility potential. The clinical indications for transcatheter embolization are much broader and include many benign gynecologic conditions, such as fibroid, adenomyosis, and arteriovenous malformations (AVMs, as well as intractable bleeding due to inoperable advanced-stage malignancies. The most well-known and well-studied indication is uterine fibroid embolization. Uterine artery embolization (UAE may be performed to prevent or treat bleeding associated with various obstetric conditions, including postpartum hemorrhage (PPH, placental implantation abnormality, and ectopic pregnancy. Embolization of the uterine artery or the internal iliac artery also may be performed to control pelvic bleeding due to coagulopathy or iatrogenic injury. This article discusses these gynecologic and obstetric indications for transcatheter embolization and reviews procedural techniques and outcomes.

  18. Cervicocephalic arterial dissection

    Suyama, Kazuhiko; Hayashi, Kentaro; Nagata, Izumi

    2008-01-01

    The authors review the clinical and neuroradiological features of cervicocephalic arterial dissection, which is occasionally seen in young adults, with special reference to the differences in the region of occurrence of these lesions between patients in Western countries and Japan. In Western countries, the cervical internal carotid artery is the most common site of occurrence of these lesions; however, in Japan, these lesions have been frequently reported to occure in the intracranial vertebral artery. Most clinical manifestations of cervical arterial dissection are non-hemorrhagic events such as headaches associated with arterial dissection or cerebral ischemia caused by a distal embolism following thrombus formation in the cervical lesion. On the other hand, a subarachnoid hemorrhage and cerebral infarction are frequently observed in intracranial arterial dissections. Non-invasive procedures, including MR imaging, are useful for demonstrating characteristic features of this condition such as the presence of an intimal flap or a double lumen, and for monitoring the chronological changes in the lesions, which may regress spontaneously. Since the pathological mechanisms underlying the progression and/or the regression of this condition are still unknown, the clinical evidence indicating the optimal therapeutic strategies has not yet been reported. Nevertheless, conservative therapy, including antithrombotic treatment, is widely used for the treatment of non-hemorrhagic lesions, which generally results in good clinical outcomes. Further, surgical intervention is essential for the treatment of lesions with a subarachnoid hemorrhage to prevent fatal rebleeding, and it is also required for the treatment of certain non-hemorrhagic lesions. Recent advancements in surgical procedures, especially endovascular treatments, may therefore be helpful in the management of similar complicated vascular conditions. (author)

    2012-01-01

    Objective: To determine the frequency of peripheral arterial disease (PAD) in type 2 diabetic patients. Study Design: Cross-sectional observational study. Place and Duration of Study: Diabetes Clinic, Medical Unit III, Jinnah Postgraduate Medical Centre, Karachi, from January to June 2010. Methodology:Three hundred and eighty seven (387) type II diabetic patients of either gender and any age were included. Patients with a previous history of trauma to the arterial vasculature, pregnancy and those who underwent in the study arterial graft procedures were excluded. Non-purposive convenient sampling technique was used to enroll patients in the study. PAD was diagnosed when ankle-brachial index (ABI) was less than 0.9. Ap-value of less than 0.05 was considered statistically significant. Results: Out of 387 studied patients, 128 were males (33.1%) and 259 were females (66.9%). Mean age was 52.22 +- 6.39 years. PAD was detected in 152 9.671 (22 - 76) years in the entire cohort. Mean duration of diabetes was 9.38 +- (39.28%) of the total study subjects. Thirty-one of 128 male patients (24.22%) had PAD disease while 121 out of 259 female patients (46.71%) had evidence of PAD (p = 0.001). Hypertension was a significantly associated factor (p = 0.002). Conclusion: A high frequency of PAD was observed in the diabetic population particularly with hypertension and more prevalent in females. (author)

  20. Arterial disease after radiotherapy

    Bigot, J.M.; Mathieu, D.; Reizine, D.

    1983-01-01

    Disease of the large arterial vessels is a relatively unknown complication of radiotherapy. However, it should be considered in the same manner as the other complications of irradiation when a tumour recurrence is suspected. The experimental studies of Kirkpatrick and Konings, demonstrating the synergy between irradiation and hypercholesterolemia in the precocity and gravity of vascular complications are recalled. The different localisations reported in the litterature are discussed: coronary, pulmonary, thoracic aorta, supra aortic, renal, digestive and ilio-femoral arteries. Finally, the difficulty of diagnosis of post-radiotherapy without clinical, radiological or anatomopathological confirmation, is underlined [fr

  1. Renal artery stenosis.

    Tafur-Soto, Jose David; White, Christopher J

    2015-02-01

    Atherosclerotic renal artery stenosis (RAS) is the single largest cause of secondary hypertension; it is associated with progressive renal insufficiency and causes cardiovascular complications such as refractory heart failure and flash pulmonary edema. Medical therapy, including risk factor modification, renin-angiotensin-aldosterone system antagonists, lipid-lowering agents, and antiplatelet therapy, is advised in all patients. Patients with uncontrolled renovascular hypertension despite optimal medical therapy, ischemic nephropathy, and cardiac destabilization syndromes who have severe RAS are likely to benefit from renal artery revascularization. Screening for RAS can be done with Doppler ultrasonography, CT angiography, and magnetic resonance angiography. Copyright © 2015 Elsevier Inc. All rights reserved.

    1990-01-01

    Xenon computed tomographic cerebral blood flow mapping was correlated with internal carotid artery stump pressures and clinical neurologic assessment during temporary internal carotid artery occlusion. One hundred fourteen patients with skull base tumors or intracranial aneurysms potentially requiring carotid resection or ligation underwent angiography, xenon CT cerebral blood flow mapping, and internal carotid artery blood pressure monitoring. The internal carotid artery was then temporarily occluded with a balloon catheter, stump pressure was measured through the catheter, and the xenon CT cerebral blood flow mapping was repeated. Adequate xenon CT cerebral blood flow was defined as greater than 30 cc/100 gm/min. All patients had normal xenon CT cerebral blood flow before internal carotid artery occlusion. During internal carotid artery occlusion, xenon CT cerebral blood flow was found to be normal (group I, 40 patients), globally reduced but still within the normal range (group II, 50 patients), or low in the distribution of the ipsilateral middle cerebral artery (group III, 13 patients). With balloon occlusion, an immediate neurologic deficit developed in 11 patients (9%) requiring deflation of the balloon preceding xenon CT cerebral blood flow measurement (group IV). In group I internal carotid artery blood pressure was 128 mm Hg. (range 85 to 171 mm Hg) with stump pressure 86 mm Hg (range 46 to 125 mm Hg). In group II internal carotid artery blood pressure was 130 mm Hg. (range 78 to 199 mm Hg), with stump pressure 86 mm Hg (range 31 to 150 mm Hg)

This method is a promising strategy for oral cancer with cervical lymph node metastasis. (author)

  9. Pharmacological modulation of arterial stiffness.

    Boutouyrie, Pierre

    2011-09-10

    Arterial stiffness has emerged as an important marker of cardiovascular risk in various populations and reflects the cumulative effect of cardiovascular risk factors on large arteries, which in turn is modulated by genetic background. Arterial stiffness is determined by the composition of the arterial wall and the arrangement of these components, and can be studied in humans non-invasively. Age and distending pressure are two major factors influencing large artery stiffness. Change in arterial stiffness with drugs is an important endpoint in clinical trials, although evidence for arterial stiffness as a therapeutic target still needs to be confirmed. Drugs that independently affect arterial stiffness include antihypertensive drugs, mostly blockers of the renin-angiotensin-aldosterone system, hormone replacement therapy and some antidiabetic drugs such as glitazones. While the quest continues for \\'de-stiffening drugs\\

    2010-01-01

    Superselective intra-arterial chemotherapy via a superficial temporal artery has become feasible for daily concurrent radiotherapy and chemotherapy in patients with oral cancer. In this study, histopathological effects on metastatic cervical lymph nodes in cases of advanced oral cancer using superselective intra-arterial chemoradiotherapy were evaluated. Thirty-seven oral cancer patients with cervical lymph node metastasis were treated with preoperative chemoradiotherapy using superselective intra-arterial infusion via the superficial temporal artery. The treatment consisted of superselective intra-arterial infusions (docetaxel, total 60 mg/m 2 ; cisplatin, total 100-150 mg/m 2 ) and concurrent radiotherapy (total 40-60 Gy) for 4-6 weeks, followed by surgery. In cases in which the catheter was inserted into the facial artery, grade III or IV (Oboshi-Shimosato classification) in the cervical lymph node metastasis was obtained in 20 (83.3%) of 24 patients. And, forty-six (88.5%) of 52 metastatic lymph nodes showed grade III or IV. This method was an effective regimen for oral cancer with cervical lymph node metastasis. (author)

    2001-10-01

    Full Text Available Diazotrophic bacteria isolated from banana plants were characterized by morphological and physiological aspects. Three different groups of these plant-bacteria could be established. Two of them showed similarity to species of the Herbaspirillum genus. The third one was different because used only a few carbon substrates and produced water diffusible compounds that fluoresced under UV light. All three bacterial groups were thin rods with mono or bipolar flagella, presented negative reaction in Gram stain, showed catalase activity, were able to reduce nitrate and grew better in semi-solid JNFb medium at 31ºC. The nitrogenase activity was detected in semi-solid N-free JNFb medium and expressed higher values when pH ranged from 6.5 to 7.0 (groups I and II and 6.0 to 6.5 (group III. The diazotrophs isolated from banana plants were distinct from species of Herbaspirillum previously identified in gramineous plants.Bactérias diazotróficas do tipo Herbaspirillum isoladas de bananeiras foram avaliadas pelas características morfológicas e fisiológicas de crescimento.

As bactérias dos três grupos eram bastonetes com flagelos mono ou bipolares, apresentaram reação negativa na coloração de Gram, expressaram atividade de catalase e oxidade, foram capazes de reduzir o nitrato e cresceram melhor em meio JNFb semi-sólido incubado a 31ºC. A atividade da nitrogenase, medida através da atividade de redução de acetileno, foi máxima em meio JNFb semi-sólido, após o ajuste de pH na faixa de 6,0 a 7,0 (grupos I e II e 5,5 a 6,5 (grupo III. As bactérias diazotróficas associadas às bananeiras são diferentes das espécies de Herbaspirillum anteriormente identificadas em gramíneas.

  19. Fusion Power Demonstration III

    Lee, J.D.

    1985-07-01

    This is the third in the series of reports covering the Fusion Power Demonstration (FPD) design study. This volume considers the FPD-III configuration that incorporates an octopole end plug. As compared with the quadrupole end-plugged designs of FPD-I and FPD-II, this octopole configuration reduces the number of end cell magnets and shortens the minimum ignition length of the central cell. The end-cell plasma length is also reduced, which in turn reduces the size and cost of the end cell magnets and shielding. As a contiuation in the series of documents covering the FPD, this report does not stand alone as a design description of FPD-III. Design details of FPD-III subsystems that do not differ significantly from those of the FPD-II configuration are not duplicated in this report

    Gunnal, Sandhya Arvind; Farooqui, Mujibuddin S; Wabale, Rajendra N

    2018-01-01

    Although posterior communicating artery (PCoA) is a smaller branch of the internal carotid artery, it gives the main contribution in the formation of circle of Willis (CW) by communicating with the internal carotid arterial system and the vertebro-basilar arterial system. The size of PCoA varies frequently. The present work aims to study the PCoA regarding its morphology, morphometry, and symmetry. This study was conducted on 170 human cadaveric brains. Brains were dissected carefully and delicately to expose all components of CW, especially PCoA. Morphological variations of PCoA were noted along with its morphometry and symmetry. Morphological variations of PCoA were aplasia (3.52%), hypoplasia (25.29%), fenestration (0.58%), and persistent fetal pattern (16.47%). In the present study, we found the five different types of terminations of PCoA. Type I termination was the most common type, seen in 92.94% of cases, Type II termination was seen in 1.17%, Type III and Type IV terminations both were seen in 0.58%, and Type V was seen in 1.17%. The mean length of PCoA was 15.9 mm and 15.3 mm on the right and left sides, respectively. The mean diameter of PCoA was 2.1 mm and 1.9 mm on the right and left sides, respectively. Symmetry of PCoA was seen in 65.29% and asymmetric PCoA was seen in 34.70% of cases. The present study provides the complete description of PCoA regarding its morphology, symmetry, and morphometry. Awareness of these anatomical variations is important in neurovascular procedures.

    2017-01-01

    Background  There are a few previous studies of the vascular anatomy of the fingertips. The aim of this study was to evaluate this anatomy and the distribution of fingertip arteries. Patients and Methods  A total of 31 cadaveric hands were used for evaluation of the vascular pattern of the fingertips on X-ray images obtained using a radiopaque material. We analyze the anatomy of the fingertip arteries, and classified it into three types in Tamai zone I. If only one dominant artery branched off from the distal transverse palmar arch, it was classified as type I. If the fingertip had branches of two dominant arteries, it was classified as type II, and if the fingertip had branches of three or more dominant arteries, it was classified as type III. Results  The incidence of type I was 27%, that of type II was 28%, and the incidence of type III was 45%, the latter being the most frequent. In addition, we analyzed the pattern in each finger. The frequency of type III decreased from the index finger to the little finger, and the frequencies of types I and II increased from the index finger to the little finger. Conclusion  Type III was the most common type in fingers, and its frequency decreased from the index finger to the little finger.

    2015-01-01

    Full Text Available Caliber-persistent artery (CPLA of the lip is a common vascular anomaly in which a main arterial branch extends to the surface of the mucous tissue with no reduction in its diameter. It usually manifests as pulsatile papule, is easily misdiagnosed, and is observed more frequently among older people, suggesting that its development may involve a degenerative process associated with aging; CPLA is also characterized by the loss of tone of the adjacent supporting connective tissue. Although the diagnosis is clinical, high-resolution Doppler ultrasound is a useful noninvasive tool for evaluating the lesion. This report describes the case of a 58-year-old male patient who complained of a lesion of the lower lip with bleeding and recurrent ulceration. The patient was successfully treated in our hospital after a diagnosis of CPLA and is currently undergoing a clinical outpatient follow-up with no complaints.

    Zimmerman, R.A.; Bilaniuk, L.T.; Hackney, D.B.; Grossman, R.I.; Goldberg, H.I.; Atlas, S.W.

    1988-01-01

    Eleven patients (ten male, one female; range, 2-56 years) presented with posterior circulation ischemic symptoms and were evaluated with computed tomography (CT) (eta=11), arteriography (eta=11), and magnetic resonance (MR) imaging (eta=6). Angiography showed dissection of a vertebral artery (eta=8), a basilar artery (eta=1), or a combination of both (eta=2). On CT and/or MR images, infarctions were demonstrated in ten of 11 cases. Most frequently involved were the thalmus (eta=7), cerebellum (eta=6), occipital lobes (eta=4), and pons (eta=3). The site of infarction did not correlate with the side or site of angiographic abnormality. In six cases evaluated by all modalities, MR imaging showed more extensive and widespread infarction than did CT and also showed whether or not the infarcts were hemorrhagic. MR imaging was able to demonstrate the presence of intramural dissecting hematoma prior to angiography and to indicate whether or not flow was reconstituted on follow-up examination

    To evaluate the clinical and radiologic findings of coronary artery fistula (CAF) by reviwing adult patients in whom this condition had been diagnosed by coronary angiogram. We retrospectively analysed the clinical findings, chest X-rays and angiographic findings of 37 adult CAF patients treated at three institutes over a period of is 15 years. On coronary angiogram, the origin of CAF was found to be the left coronary artery (LCA) in 20 cases(54%), the right coronary artery (RCA) in five (14%), and both in 12(32%). By subdividing the coronary artery into four segments [RCA, left main coronary artery, left anterior descending artery(LAD), and left circumflex artery(LCX)], the origin of CAF (total 55 cases) was found to be the LAD in 23 cases(42%), the LCX in 12(22%), the left main coronary artery in three (5%), and the RCA in 17(31%). The draining site of CAF was the right heart [right atrium, right ventricle, and main pulmonary artery(MPA)] in 28 cases(75%) the left heart(left atrium and left ventricle) in 8(22%), and both in one (3%). The fistula drained to the cardiac chamber in 12 cases (33%), the MPA in 23(62%), and both in 2(5%). Among 55 cases, the total number of fistulas to the MPA was 35, and their origin was the RCA in nine instances (26%), and the left coronary artery in 26(74%). CAF to the MPA was classified into four types:Type I(single, tortuous and not dilated) was seen in six patients (17%), type II(single, tortuous and dilated) in three (9%), type III(multiple and fine plexus) in 21(60%), and type IV(multiple and dilated plexus)in five (14%). Eighteen cases (49%) were associated with the other cardiac disease. In these Korean adults, CAF originated most commonly from the LCA, especially from the LAD segment of this artery, and most frequently drained to the right cardic chamber, especially to the MPA. The morphology of the CAF to the MPA was mostly multiple and fine plexus. We suggest that to ensure the most suitable treatment, and for better

    Two patients with unilateral popliteal artery entrapment syndrome (PAES) are reported. The importance of diligence in angiographic diagnosis and recognition of the so-called 'functional' PAES group as a separate entity are stressed. It is inferred from our material that a surgical approach for PAES is to be advocated since surgical release of the entrapment can lead to complete resolution of symptoms regardless of aetiology.

    Full Text Available Aim. A case is reported of successfully surgically treated explosive war injury to the innominate artery. Case report. A 26 - year-old soldier was injured in combat by a fragment of mortar shell. In the field hospital, the wound gauze packing was applied, followed by orotracheal intubation and thoracic drainage. The soldier was admitted to MMA six hours later. Physical examination, on admission, revealed huge swelling of the neck, the absence of pulse in the right arm and the right common carotid artery. Chest x-ray revealed hemopneumothorax of the right side and the foreign metal body in the projection of the right sternoclavicular joint. Due to the suspicion of large vessel injury, a median sternotomy was immediately performed. Surgery revealed disrupted bifurcation of the right innominate artery, so the ligation was performed. Aortography was performed postoperatively, followed by the reconstruction of innominate bifurcation with synthetic grafts. Control aortography showed good graft patency, and the patient was discharged from the hospital in good general condition with palpable pulses and mild anisocoria as a sole neurological sequela. Conclusion. A rare and life-threatening injury was successfully managed, mainly due to the rational treatment carried out in the field hospital that helped the injured to survive and arrive to the institution capable of performing the most sophisticated diagnostic and therapeutic procedures.

    Full Text Available Abstract The renal artery pseudoaneurysm embody a rare vascular complication coming of percutaneous procedures, renal biopsy, nephrectomy, penetrating traumas and more rarely blunt traumas. The clinical can be vary according the patient, the haematuria is the symptom more commom. Is necessary a high level of clinical suspicion for your diagnosis, this can be elucidated by through complementary exams as the eco-color Doppler and the computed tomography scan (CT. This report is a case of a patient submitted a right percutaneous renal biopsy and that, after the procedure started with macroscopic haematuria, urinary tenesmus and hypogastric pain. The diagnosis of pseudoaneurysm was given after one week of evolution when the patient was hospitalized because gross haematuria, tachycardia, hypotension and hypochondrium pain. In the angiotomography revealed a focal dilation of the accessory right renal inferior polar artery, dilation of renal pelvis and all the ureteral course with presence hyperdenso material (clots inside the middle third of the ureter. The treatment for the majority of this cases are conservative, through arterial embolization, indicated for thouse of smaller dimensions in patients who are hemodynamically stable. However, it was decided by clinical treatment with aminocaproic acid 1 g, according to previous studies for therapy of haematuria. The patient received discharge without evidence of macroscopic haematuria and with normal renal ultrasound, following ambulatory care.

    Objective: To investigate the clinical values of preoperative arterial infusion chemotherapy and surgical operation for colorectal carcinoma. Methods: 66 patients with colorectal carcinoma were subjected to percutaneous femoral artery catheterization by Seldinger's technique with infusion of anti-cancer drugs. The resection was performed 5-30 days after the arterial infusion (mean 12 days). In 50 surgical specimens of the 66 cases, histological findings were evaluated including the density and distribution of the apoptosis cells under the observation by DNA nick end labelling technique. Of which 22 specimens before arterial infusion chemotherapy (got from biopsy of preoperation) and 25 normal mucosa (got from normal surgical specimens) were used as controls. Results: The total histological response rate was 100% with grade I in 20 cases, grade II in 21 cases, grade III in 9 cases. The densities of the apoptosis cells were 31.47 ± 5.58 before arterial infusion chemotherapy, 76.69 ± 17.12 after arterial infusion chemotherapy and 8.01 ± 3.39 in normal mucosa. The density of the apoptosis cells after arterial infusion chemotherapy was significantly higher than that before arterial infusion chemotherapy (P 2 =4.696, P>0.30). There were no significant differences in the apoptosis of adenocarcinoma during different pathological stages (F=0.001376, P>0.05). Conclusions: Peroperative transcatheter arterial infusion chemotherapy resulting in apoptosis of adenocarcinoma, can raise the radical operation rate, and prolong survival rate for colorectal carcinoma patients

  19. Sphingosine-1-Phosphate Signaling Regulates Myogenic Responsiveness in Human Resistance Arteries.

    Sonya Hui

    Full Text Available We recently identified sphingosine-1-phosphate (S1P signaling and the cystic fibrosis transmembrane conductance regulator (CFTR as prominent regulators of myogenic responsiveness in rodent resistance arteries. However, since rodent models frequently exhibit limitations with respect to human applicability, translation is necessary to validate the relevance of this signaling network for clinical application. We therefore investigated the significance of these regulatory elements in human mesenteric and skeletal muscle resistance arteries. Mesenteric and skeletal muscle resistance arteries were isolated from patient tissue specimens collected during colonic or cardiac bypass surgery. Pressure myography assessments confirmed endothelial integrity, as well as stable phenylephrine and myogenic responses. Both human mesenteric and skeletal muscle resistance arteries (i express critical S1P signaling elements, (ii constrict in response to S1P and (iii lose myogenic responsiveness following S1P receptor antagonism (JTE013. However, while human mesenteric arteries express CFTR, human skeletal muscle resistance arteries do not express detectable levels of CFTR protein. Consequently, modulating CFTR activity enhances myogenic responsiveness only in human mesenteric resistance arteries. We conclude that human mesenteric and skeletal muscle resistance arteries are a reliable and consistent model for translational studies. We demonstrate that the core elements of an S1P-dependent signaling network translate to human mesenteric resistance arteries. Clear species and vascular bed variations are evident, reinforcing the critical need for further translational study.

    Our aim was to treat a clinically silent renal artery aneurysm. The patient was a 76-year-old man with elevated prostate-specific antigen and prostata biopsies with a gradus II-III adenocarcinoma who was incidentally found to have an aneurysm in his right renal artery. We performed a successful transcatheter embolization of the aneurysm using ethylene vinyl alcohol copolymer (Onyx). To avoid migration of the liquid material into the parent artery, a balloon was inflated in the orifice of the neck of the aneurysm while the liquid was injected. Five-month follow-up computed tomography (CT) imaging confirmed total occlusion of the aneurysm

  2. Coronary Artery Anomalies in Animals

    Brian A. Scansen

    2017-04-01

    Full Text Available Coronary artery anomalies represent a disease spectrum from incidental to life-threatening. Anomalies of coronary artery origin and course are well-recognized in human medicine, but have received limited attention in veterinary medicine. Coronary artery anomalies are best described in the dog, hamster, and cow though reports also exist in the horse and pig. The most well-known anomaly in veterinary medicine is anomalous coronary artery origin with a prepulmonary course in dogs, which limits treatment of pulmonary valve stenosis. A categorization scheme for coronary artery anomalies in animals is suggested, dividing these anomalies into those of major or minor clinical significance. A review of coronary artery development, anatomy, and reported anomalies in domesticated species is provided and four novel canine examples of anomalous coronary artery origin are described: an English bulldog with single left coronary ostium and a retroaortic right coronary artery; an English bulldog with single right coronary ostium and transseptal left coronary artery; an English bulldog with single right coronary ostium and absent left coronary artery with a prepulmonary paraconal interventricular branch and an interarterial circumflex branch; and a mixed-breed dog with tetralogy of Fallot and anomalous origin of all coronary branches from the brachiocephalic trunk. Coronary arterial fistulae are also described including a coronary cameral fistula in a llama cria and an English bulldog with coronary artery aneurysm and anomalous shunting vessels from the right coronary artery to the pulmonary trunk. These examples are provided with the intent to raise awareness and improve understanding of such defects.

    2009-01-01

    The purpose of this study was to describe clinical and computed tomography (CT) findings of isolated dissection of the visceral arteries (IDVA). We retrospectively analyzed clinical presentation and abdominal CT findings of 38 patients who were diagnosed as having an IDVA. IDVA were classified into three types based on CT findings: patent false lumen with re-entry (type I), patent false lumen without re-entry (type II), and completely thrombosed false lumen (type III). The dissection was located in the superior mesenteric artery (SMA) in 27 patients, celiac artery (CA) in 6, CA to splenic artery in 2, and common hepatic artery (CHA), CA to CHA, and inferior mesenteric artery (IMA) in 1 patient each. The dissection was classified into type I in 8 patients, type II in 12, and type III in 18. Surgical treatment was performed in 1 patient with type II SMA dissection because of bowel ischemia, although the remaining 37 patients were managed conservatively. Two cases with type II showed a progressive enlargement of the false lumen in follow-up CT. Increased density of the fat tissue around the affected visceral artery was more commonly seen in symptomatic patients compared to asymptomatic ones (P<0.01). Based on our observation, patients with IDVA can be managed conservatively when there are no signs indicating organ ischemia. (author)

    Microscopic cerebral arterial air embolism (CAAE) has been described in many patients undergoing cardiac surgery as well as other invasive diagnostic and therapeutic procedures. However, massive CAAE is rare. We report a 42-year-old woman who initially presented with thalamic and basal ganglia hemorrhages. Shortly after a radial arterial catheter was inserted, the patient suffered a generalized seizure and CT demonstrated intra-arterial air in bilateral cerebral hemispheres. (orig.)

    1993-07-15

    In order to study the clinical efficacy of the metallic stent of the treatment of iliac arterial stenosis, the clinical and arteriographic findings of the 8 patients were retrospectively reviewed. All 8 patients were males with an age of 51 to 79. The Fontaine class for the functional status of lower extremities was II in 4 patients, III in 3 patents and IV in 1 patient. Self expandable Gianturco stent was inserted of in 7 iliac arteries and balloon expandable Palmaz stent was inserted in 2 iliac arteries in the 8 patients. The indications for the metallic stent application were localized dissection with significant residual stenosis in 6 sites, recoiling due to calcification in one case and eccentricity of the stenosislesionin 2 sites. The deployment of the metallic stent was successful in all the cases to maintain the patency of iliac arteries with residual stenosis less than 30%. The Fontaine class was improved to 1 in 6 patients, IIa in 1 patient and IIb in another one. During the follow up period of 3 to 14 month, none except one developed recurrence of the symptom. On the basis of our experience, we believe that metallic stent is safe and effective for the treatment of iliac arterial stenosis. However, we think that it is a complementary measure to the percutaneous transluminal angioplasty. The comparative study between different types of metallic stent and the long term effect should be investigated further.

  8. Role of Peroxiredoxin III in the Pathogenesis of Pre-eclampsia as Evidenced in Mice

    Lianqin Li

    2010-01-01

    Full Text Available As a member of peroxiredoxin (Prx family, PrxIII has been demonstrated to play an important role in scavenging intracellular reactive oxygen species (ROS. Since PrxIII knockout mice exhibited oxidative stress in placentas resembling pathophysiologic changes in placentas of human pre-eclampsia, we measured blood pressure through the carotid artery and detected oxidative status by western blotting in pregnant mice. We did not notice hypertension in pregnant PrxIII knockout mice as compared with wild-type littermates, although endothelin-1 was overexpressed in PrxIII-deficient placentas. Our results indicate that PrxIII is not involved in pre-eclamptic development. Instead, PrxIII is an indispensable antioxidant in placentas where oxidative stress exists.

    1990-01-01

    The superficial temporal artery has been thought to be the main focus of pain during migraine attacks, but its diameter has never been measured directly. The use of a new, high-resolution ultrasound machine to measure arterial size in 25 migraine patients with unilateral head pain showed...... that the lumen was wider on the painful than on the non-painful side during a migraine attack. The diameters of both radial arteries and the temporal artery on the non-painful side were smaller during than between attacks. The generalised vasoconstriction was not shared by the temporal artery on the affected...... side, which suggests a local vasodilatory response. The findings suggest that cephalic arteries may play a role in migraine pathogenesis....

  10. Pulmonary Arterial Hypertension and Neonatal Arterial Switch Surgery for Correction of Transposition of the Great Arteries.

    Domínguez Manzano, Paula; Mendoza Soto, Alberto; Román Barba, Violeta; Moreno Galdó, Antonio; Galindo Izquierdo, Alberto

    2016-09-01

    There are few reports of the appearance of pulmonary arterial hypertension following arterial switch surgery in the neonatal period to correct transposition of the great arteries. We assessed the frequency and clinical pattern of this complication in our series of patients. Our database was reviewed to select patients with transposition of the great arteries corrected by neonatal arterial switch at our hospital and who developed pulmonary hypertension over time. We identified 2 (1.3%) patients with transposition of the great arteries successfully repaired in the first week of life who later experienced pulmonary arterial hypertension. The first patient was a 7-year-old girl diagnosed with severe pulmonary hypertension at age 8 months who did not respond to medical treatment and required lung transplantation. The anatomic pathology findings were consistent with severe pulmonary arterial hypertension. The second patient was a 24-month-old boy diagnosed with severe pulmonary hypertension at age 13 months who did not respond to medical therapy. Pulmonary hypertension is a rare but very severe complication that should be investigated in all patients with transposition of the great arteries who have undergone neonatal arterial switch, in order to start early aggressive therapy for affected patients, given the poor therapeutic response and poor prognosis involved.

    1984-01-01

    In catheter methods in dogs the knowledge of the roentgenologic anatomy of blood vessels is very important. Because of lacking in such roentgenologic anatomic schemes 5 arterial schemes in relation to the skeleton were elaborated. The system of arteries was divided into five regions: chest, head and neck in submentooccipital and lateral projection, abdomen and pelvis. The schemes comprise 75 of the main arteries of the dog.

  12. [The effect of calcitonin gene-related peptide on collagen accumulation in pulmonary arteries of rats with hypoxic pulmonary arterial hypertension].

    Li, Xian-Wei; Du, Jie; Li, Yuan-Jian

    2013-03-01

    To observe the effect of calcitonin gene-related peptide (CGRP) on pulmonary vascular collagen accumulation in hypoxia rats in order to study the effect of CGRP on hypoxic pulmonary vascular structural remodeling and its possible mechanism. Rats were acclimated for 1 week, and then were randomly divided into three groups: normoxia group, hypoxia group, and hypoxia plus capsaicin group. Pulmonary arterial hypertension was induced by hypoxia in rats. Hypoxia plus capsaicin group, rats were given capsaicin (50 mg/(kg x d), s.c) 4 days before hypoxia to deplete endogenous CGRP. Hypoxia (3% O2) stimulated proliferation of pulmonary arterial smooth muscle cells (PASMCs) and proliferation was measured by BrdU marking. The expression levels of CGRP, phosphorylated ERK1/2 (p-ERK1/ 2), collagen I and collagen III were detected by real-time PCR or Western blot. Right ventricle systolic pressure (RVSP) and mean pulmonary arterial pressure (mPAP) of pulmonary arterial hypertension (PAH) rats induced by hypoxia were higher than those of normoxia rats. By HE and Masson staining, it was demonstrated that hypoxia also significantly induced hypertrophy of pulmonary arteries and increased level of collagen accumulation. Hypoxia dramatically decreased the CGRP level and increased the expression of p-ERK1/2, collagen I, collagen III in pulmonary arteries. All these effects of hypoxia were further aggravated by pre-treatment of rats with capsaicin. CGRP concentration-dependently inhibited hypoxia-induced proliferation of PASMCs, markedly decreased the expression of p-ERK1/2, collagen I and collagen III. All these effects of CGRP were abolished in the presence of CGRP8-37. These results suggest that CGRP might inhibit hypoxia-induced PAH and pulmonary vascular remodeling, through inhibiting phosphorylation of ERK1/2 and alleviating the collagen accumulation of pulmonary arteries.

    Acuna Allen, Rafael

    2011-01-01

    A bibliographic review is realized in the arterial mapping of lower limbs by ultrasonographic. The physical properties of the Doppler effect applied to diagnostic ultrasound are described. The anatomical characteristics of the general arterial system and specifically of the lower limbs arterial system are mentioned. Pathologies of the ischemic arterial disease of lower limbs are explained. The study characteristics of lower limbs arterial mapping are documented to determine its importance as appropriate method for the assessment of lower limb ischemia. An adequate arterial mapping of lower limbs is recognized in atherosclerotic ischemic disease as a reliable initial method alternative to arteriography. Arteriography is considered as reference pattern for therapeutic decision making in patients with critical ischemia of the lower limbs. Non-invasive methods to assess the arterial system of lower limbs has evidenced the advantages of the arterial mapping with Doppler, according to the consulted literature. The combination morphological and hemodynamic information has been possible and a map of the explored zone is made. The arterial mapping by ultrasonography has offered similar reliability to angiography [es

  14. Elective visceral hybrid repair of type III thoracoabdominal aortic aneurysm

    Marjanović Ivan

    2012-01-01

    Full Text Available Introduction. According to the classification given by Crawford et al. type III thoracoabdominal aortic aneurysm (TAAA is dilatation of the aorta from the level of the rib 6 to the separation of the aorta below the renal arteries, capturing all the visceral branch of aorta. Visceral hybrid reconstruction of TAAA is a procedure developed in recent years in the world, which involves a combination of conventional, open and endovascular aortic reconstruction surgery at the level of separation of the left subclavian artery to the level of visceral branches of aorta. Case report. We presented a 75-years-old man, with elective visceral hybrid reconstruction of type III TAAA. Computerized scanning (CT angiography of the patient showed type III TAAA with the maximum transverse diameter of aneurysm of 92 mm. Aneurysm started at the level of the sixth rib, and the end of the aneurysm was 1 cm distal to the level of renal arteries. Aneurysm compressed the esophagus, causing the patient difficulty in swallowing act, especially solid food, and frequent back pain. From the other comorbidity, the patient had been treated for a long time, due to chronic obstructive pulmonary disease and hypertension. In general endotracheal anesthesia with epidural analgesia, the patient underwent visceral hybrid reconstruction of TAAA, which combines classic, open vascular surgery and endovascular procedures. Classic vascular surgery is visceral reconstruction using by-pass procedure from the distal, normal aorta to all visceral branches: celiac trunk, superior mesenteric artery and both renal arteries, with ligature of all arteries very close to the aorta. After that, by synchronous endovascular technique a complete aneurysmal exclusion of thoracoabdominal aneurysm with thoracic stent-graft was performed. The postoperative course was conducted properly and the patient left the Clinic for Vascular Surgery on postoperative day 21. Control CT, performed 3 months after the surgery

    Carotid artery dissection is an important cause of ischemic stroke in all age groups, particularly in young patients. The purpose of this work was to assess whether there is an association between the presence of an internal carotid artery dissection (ICAD) and the arterial tortuosity. This study considered 124 patients (72 males and 52 females; median age 57 years) with CT/MR diagnosis of ICAD of the internal carotid artery were considered in this multi-centric retrospective study. The arterial tortuosity was evaluated and, when present, was categorized as elongation, kinking, or coiling. For each patient, both the right and left sides were considered for a total number of 248 arteries in order to have the same number of cases and controls. Fisher's exact test was applied to test the association between elongation, kinking, coiling, dissection, and the side affected by CAD. Fisher's exact test showed a statistically significant association between the ICAD and kinking (p = 0.0089) and coiling (p = 0.0251) whereas no statistically significant difference was found with arterial vessel elongation (p = 0.444). ICAD was more often seen on the left side compared to the right (p = 0.0001). These results were confirmed using both carotid arteries of the same patient as dependent parameter with p = 0.0012, 0.0129, and 0.3323 for kinking, coiling, and elongation, respectively. The presence of kinking and coiling is associated with ICAD. (orig.)

  2. Hepatic artery perfusion imaging

    1985-01-01

    Organ and region-selective intra-arterial chemotherapy have been used for more than two decades to treat malignant neoplasms in the extremities, head and neck region, pelvis, liver, and other areas. Substantial evidence of improved response to regional chemotherapy now exists, but there are stringent requirements for successful application of the regional technique. First, the chemotherapeutic agent employed must have appropriate pharmacokinetic and pharmacodynamic properties. Second, the drug must be reliably delivered to the tumor-bearing area. This typically requires an arteriographic assessment of the vascular supply of the tumor, followed by placement of a therapeutic catheter and confirmation that the ''watershed'' perfusion distribution from the catheter truly encompasses the tumor. Optimal catheter placement also minimizes perfusion of nontarget organs. Radionuclide perfusion imaging with technetium 99m-labeled particles, either microspheres or macroaggregates of albumin, has become the method of choice for making these assessments. Catheter placement itself is considered by many to represent a type of ''therapeutic'' intervention. However, once the catheter is in the hepatic artery the radionuclide perfusion technique can be used to assess adjunctive pharmacologic maneuvers designed to further exploit the regional approach to chemotherapy. This chapter presents the technetium Tc 99m macroaggregated albumin method for assessing catheter placement and the pharmacokinetic rationale for regional chemotherapy, and discusses two promising avenues for further intervention

    Brandt, Tobias; Caplan, Louis

    2001-09-01

    There is no controlled study for the best treatment or management of cervico-cerebral artery dissection (CAD). Rationale initial empiric treatment in acute CAD to prevent secondary embolism is partial thromboplastin time (PTT)-guided anticoagulation by intravenous heparin followed by anticoagulation with warfarin. Carotid surgery for treatment of CAD is not recommended anymore with the possible exception of persisting severe stenosis of the proximal internal carotid artery (ICA). There could be use of carotid angioplasty by balloon dilatation and stenting in selected cases of severe cerebral hemodynamic impairment by bilateral CAD. Duration of secondary prophylaxis by anticoagulation is best guided by Doppler sonography follow-up, and should be continued until normalization of blood flow or until at least 1 year after the vessel is occluded. There is no evidence that pseudoaneurysms increase the risk for embolic complication, and there is no evidence for surgery or continuation of anticoagulation in patients with pseudoaneurysms. Caution should be recommended for exercises that involve excessive head movements (eg, bungee jumping, trampoline jumping, and chiropractic maneuvers). The patient should be informed that recurrent rate is low in nonfamilial cases. Doppler sonography is a low-cost and high-sensitivity method for patients at risk.

  11. Arterial stiffness and cognitive impairment.

    Li, Xiaoxuan; Lyu, Peiyuan; Ren, Yanyan; An, Jin; Dong, Yanhong

    2017-09-15

    Arterial stiffness is one of the earliest indicators of changes in vascular wall structure and function and may be assessed using various indicators, such as pulse-wave velocity (PWV), the cardio-ankle vascular index (CAVI), the ankle-brachial index (ABI), pulse pressure (PP), the augmentation index (AI), flow-mediated dilation (FMD), carotid intima media thickness (IMT) and arterial stiffness index-β. Arterial stiffness is generally considered an independent predictor of cardiovascular and cerebrovascular diseases. To date, a significant number of studies have focused on the relationship between arterial stiffness and cognitive impairment. To investigate the relationships between specific arterial stiffness parameters and cognitive impairment, elucidate the pathophysiological mechanisms underlying the relationship between arterial stiffness and cognitive impairment and determine how to interfere with arterial stiffness to prevent cognitive impairment, we searched PUBMED for studies regarding the relationship between arterial stiffness and cognitive impairment that were published from 2000 to 2017. We used the following key words in our search: "arterial stiffness and cognitive impairment" and "arterial stiffness and cognitive impairment mechanism". Studies involving human subjects older than 30years were included in the review, while irrelevant studies (i.e., studies involving subjects with comorbid kidney disease, diabetes and cardiac disease) were excluded from the review. We determined that arterial stiffness severity was positively correlated with cognitive impairment. Of the markers used to assess arterial stiffness, a higher PWV, CAVI, AI, IMT and index-β and a lower ABI and FMD were related to cognitive impairment. However, the relationship between PP and cognitive impairment remained controversial. The potential mechanisms linking arterial stiffness and cognitive impairment may be associated with arterial pulsatility, as greater arterial pulsatility

  13. Anatomical Relationship Between the Kidney Collecting System and the Intrarenal Arteries in the Sheep: Contribution for a New Urological Model.

    Buys-Gonçalves, Gabriela Faria; De Souza, Diogo Benchimol; Sampaio, Francisco José Barcellos; Pereira-Sampaio, Marco Aurélio

    2016-04-01

    Previous studies have demonstrated that the pig collecting system heals after partial nephrectomy without closure. Recently, a study in sheep showed that partial nephrectomy without closure of the collecting system resulted in urinary leakage and urinoma. The aim of this study was to present detailed anatomical findings on the intrarenal anatomy of the sheep. Forty two kidneys were used to produce tridimensional endocasts of the collecting system together with the intrarenal arteries. A renal pelvis which displayed 11-19 (mean of 16) renal recesses was present. There were no calices present. The renal artery was singular in each kidney and gave two primary branches one to the dorsal surface and one to ventral surface. Dorsal and ventral branches of the renal artery were classified based on the relationship between their branching pattern and the collecting system as: type I (cranial and caudal segmental arteries), type II (cranial, middle and caudal segmental arteries) or type III (cranial, cranial middle, caudal middle, and caudal segmental arteries). Type I was the most common branching pattern for the dorsal and ventral branches of the renal artery. The arterial supply of the caudal pole of the sheep kidney supports its use as an experimental model due to the similarity to the human kidney. However, the lack of a retropelvic artery discourages the use of the cranial pole in experiments in which the arteries are an important aspect to be considered. © 2016 Wiley Periodicals, Inc.

  14. Patent arterial duct

    Martin Robin P

    2009-07-01

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

    Quesnel, C.; Maquin, P.; Railhac, N.; Lefevre, G.; Bossavy, J.B.; Railhac, J.J.

    1988-01-01

    Twenty-one femoropopliteal percutaneous transluminal atherectomies were performed with the Simpson catheter. Evaluation included clinical examination, Doppler ultrasonography (ankle-arm index, before and immediately and 1,3 and 6 months after atherectomy), and angiography (6 months after or for clinical worsening). Twenty of 21 procedures achieved satisfactory vessel patency, with the addition of complementary angioplasty for residual stenosis over 30% (one of three cases). Early thrombosis occurred in only one of 21 cases (absence of platelet inhibitor pretherapy), and no distal embolization occurred. Six-month follow-up showed stable improvements in 11 of 12 patients and restenosis in only one (absence of platelet inhibitor pretherapy). Preliminary results indicate that atherectomy is the method of choice for restoring large lumens, with minimal arterial wall injury and fewer cases of restenosis than with angioplasty

    de Simone, Giovanni; Mancusi, Costantino; Esposito, Roberta; De Luca, Nicola; Galderisi, Maurizio

    2018-05-02

    Hypertension is a condition characterized by pressure and/or volume overloads and echocardiography is helpful and feasible to understand hemodynamic mechanisms. Echocardiographic information is sometimes critical and susceptible of modifying decision making. In this review, we provide detailed descriptions of the parameters that can be derived from a standard transthoracic echocardiogram, including some more recent techniques. We will also explain how each parameter might have impact in the evaluation of the hypertensive patient and give indications on when to refer patients to echo-labs, which parameters are critical and which ones might be redundant, and how to use the information obtained in the report. Cardiac geometry, LV systolic and diastolic function, LV pump performance, output impedance and left atrial function are parameters that might be altered in arterial hypertension, but not necessarily doctors need the whole information for decision making. The critical measures are provided.

  20. [Exercise in arterial hypertension].

    Predel, Hans-Georg; Schramm, Thomas

    2006-09-01

    Regular endurance training has established itself as a major therapeutic principle in the specter of nonpharmacological measures in arterial hypertension. An initial medical check as well as an adequate technique, dosage and intensity of the prescribed exercise training are mandatory. With respect to the concomitant pharmacological treatment, it should be considered that the beneficial effects of lifestyle modification will not be counteracted by the chosen antihypertensive drug but, ideally, synergistically supported. Based on the individual clinical situation, principally all antihypertensive drugs recommended by the current European guidelines, may be prescribed as mono- or combination therapy.beta-receptor blockers are especially capable of controlling excessive exercise-induced blood pressure increase; however, they have metabolic and exercise physiological limitations. The neutrality concerning metabolic and exercise physiological parameters as well as the positive profile of side effects favor ACE inhibitors, long-acting calcium channel blockers and especially AT(1) antagonists in physically active hypertensive patients with concomitant metabolic syndrome.

  2. Retinal artery occlusion during carotid artery stenting with distal embolic protection device.

    Kohara, Kotaro; Ishikawa, Tatsuya; Kobayashi, Tomonori; Kawamata, Takakazu

    2018-01-01

    Retinal artery occlusion associated with carotid artery stenosis is well known. Although it can also occur at the time of carotid artery stenting, retinal artery occlusion via the collateral circulation of the external carotid artery is rare. We encountered two cases of retinal artery occlusion that were thought to be caused by an embolus from the external carotid artery during carotid artery stenting with a distal embolic protection device for the internal carotid artery. A 71-year-old man presented with central retinal artery occlusion after carotid artery stenting using the Carotid Guardwire PS and a 77-year-old man presented with branch retinal artery occlusion after carotid artery stenting using the FilterWire EZ. Because additional new cerebral ischaemic lesions were not detected in either case by postoperative diffusion-weighted magnetic resonance imaging, it was highly likely that the debris that caused retinal artery occlusion passed through not the internal carotid artery but collaterals to retinal arteries from the external carotid artery, which was not protected by a distal embolic protection device. It is suggested that a distal protection device for the internal carotid artery alone cannot prevent retinal artery embolisation during carotid artery stenting and protection of the external carotid artery is important to avoid retinal artery occlusion.

    Endovascular treatment of peripheral arterial disease (PAD) involving the tibial arteries is becoming an increasingly important part of revascularization. The current anatomical description of vessel patency in tibial arteries does not contribute effectively to therapeutic strategies. The Joint Endovascular and Non-Invasive Assessment of Limb Perfusion (JENALI) score, is a novel scoring system developed to further assess patency of tibial arteries, via both angiography and arterial duplex ultrasonography. A comparison was made between the JENALI score obtained by ultrasound and by angiography. Angiography is currently considered the gold standard of tibial artery imaging. This prospective single-center study involved 49 patients undergoing peripheral angiography for evaluation of PAD, between November 2011 and November 2012. All patients underwent a detailed ultrasound assessment of the tibial arteries ± 7 days from diagnostic angiography. Eligible patients had a Rutherford score ≥ III or abnormal ankle-brachial index values. Angiography and ultrasound were evaluated in a blinded fashion. Average age of patients was 69.8 years. A total of 846 segments were assessed by both angiography and ultrasound. We found that 648 segments (76.6%) were deemed to be patent by angiography compared to 723 (85.5%) by ultrasound. Critical limb ischemia (CLI; Rutherford score ≥ 4) was described in 26 patients (53%). Average JENALI score for the right lower extremity was 7.0 by angiogram vs 7.7 by ultrasound. The average JENALI score of the left leg was 6.7 by angiogram vs 7.7 by ultrasound. A total of 94 lower extremities were assigned a JENALI score. Ultrasound was accurate in detecting tibial artery patency or occlusion in 80% of segments. The overall sensitivity/specificity of ultrasound detecting tibial artery patency was calculated at 93% and 40% (P<.05), respectively. Detection of patency via ultrasound was highest for the anterior tibial artery and the lowest for the

    Full Text Available Cualquier intervención farmacéutica debe presentar como objetivo principal mejorar los resultados de salud. Asimismo, es preciso tener en consideración que un resultado, que es la consecuencia obtenida a partir de la utilización de los distintos recursos, es un beneficio por el que se aumenta el bienestar individual o social. En función del tipo de beneficio obtenido, los resultados se clasifican en dos clases principales: los sanitarios y los no sanitarios. Muy probablemente, el farmacéutico comunitario está más habituado a manejarse con los primeros, puesto que se asocian con las variables habituales, como los mmHg para medir la presión arterial o los mg/dL para hacerlo con la glucemia en plasma o bien mediante el número de exacerbaciones que se producen en una EPOC o el porcentaje de casos resueltos con curación clínica y bacteriológica en una neumonía adquirida en la comunidad. Los resultados anteriores forman parte de los denominados intermedios, pero también el farmacéutico ha manejado variables finales, como es la supervivencia cuando se halla frente a un paciente que ha sufrido un infarto agudo de miocardio y expresa la efectividad de una determinada tecnología sanitaria mediante la probabilidad de supervivencia al cabo de treinta días. No obstante, es probable que el farmacéutico esté menos habituado a manejarse con otros resultados cuyo tipo no sea el sanitario clásico y que están relacionados con la calidad de vida relacionada con la salud (CVRS.

  6. Arterial complications of vascular Ehlers-Danlos syndrome.

    Eagleton, Matthew J

    2016-12-01

    Vascular Ehlers-Danlos syndrome (EDS) is a relatively rare genetic syndrome that occurs owing to disorders in the metabolism of fibrillary collagen. These defects affect the soft connective tissues resulting in abnormalities in the skin, joints, hollow organs, and blood vessels. Patients with these defects frequently present at a young age with spontaneous arterial complications involving the medium-sized arteries. Complications involving the hollow organs, such as spontaneous colonic perforation, are observed as well. Given the fragility of the soft tissue, open and endovascular intervention on patients with vascular EDS is fraught with high complication rates. A PubMed search was performed to identify manuscripts published related to vascular EDS. This search included more than 747 articles. These findings were cross-referenced using key terms, including endovascular, embolization, surgery, genetics, pathophysiology, connective tissue disorders, vascular complications, systematic review, type III collagen, and COL3A1. The references in key articles and review articles were evaluated for additional resources not identified in the PubMed search. Care must be taken to balance the risk of intervention vs the risk of continued observation. Life-threatening hemorrhage, however, mandates intervention. With careful, altered approaches to tissue handling, endovascular approaches may provide a safer option for managing the arterial complications observed in patients with vascular EDS. Additional hope may also be found in the use of pharmacologic agents that reduce the incidence and severity of the arterial complications. Copyright © 2016 Society for Vascular Surgery.

Foram instalados testes de germinação em delineamento inteiramente ao acaso, no esquema fatorial 8 x 2 (genótipos: CCN51, PH16, CEPEC2002, Ipiranga, SJ02, PS1319, TSH1188 e Comum x dois períodos de armazenamento: 0 e dois dias. O genótipo TSH1188 apresentou maior comprimento, relação comprimento/largura, espessura e massa de 100 sementes. A absorção de água das sementes recém-colhidas dos genótipos é lenta, justificada pelos altos teores de água, o que não caracteriza padrão-trifásico. Os teores de água reduziram em média 2,3 vezes nas sementes armazenadas em relação às recém-colhidas. A germinação das sementes recém-colhidas dos genótipos foi de 100%. Após o armazenamento, as sementes do PS1319 apresentaram a menor redução da germinação (39%, enquanto as dos PH16, CEPEC2002 e SJ02 reduziram 96%. A velocidade de germinação foi maior e o tempo médio menor que dois dias nas sementes recém-colhidas do PS1319, indicando serem mais tolerante à dessecação. Sugere-se o uso dos genótipos TSH1188 e PS1319 em programas de melhoramento genético.

  20. Cerebellar arteries originating from the internal carotid artery: angiographic evaluation and embryologic explanations

    Lee, Jae Young; Han, Moon Hee; Yu, In Gyu; Chang, Ki Hyun; Kim, Eui Jong; Kim, Dae Ho

    1997-01-01

    To find and describe the cerebellar arteries arising from the internal carotid artery, explain them embryologically, and evaluate their clinical implication. To determine the point in the internal carotid artery from which the cereballar artery arose anomalously, consecutive angiographic studies performed in the last three years were reviewed. The distribution of such anomalous cerebellar arteries, the point in the internal carotid artery from which the anomalous vessels originated, and associated findings were analyzed. Five anomalous origins of cerebellar arteries arising arising directly from the internal carotid artery were found in five patients. Three anterior inferior cerebellar arteries (AICA) and one common trunk of an AICA and a posterior inferior cerebellar artery (PICA) were found to originate from the internal carotid artery at a point close to the origin of the primitive trigeminal artery. A PICA arose from an artery presenting a course similar to the proatlantal intersegmental artery. Intracranial aneurysms in two patients, Moyamoya disease in one, and facial arteriovenous malformation in one. In our series, AICAs supplied from the arteries considered to be persistent trigeminal artery variants were the most common type. A correlation between type of anomalous cerebellar artery and type of carotid-vertebrobasilar anastomosis may exist. Cerebellar arteries originating anomalously from the internal carotid artery seem to occur as a result of the persistence of carotid-vertebrobasilar anastomoses associated with incomplete fusion of the longitudinal neural arteries. An understanding of these anomalous cerebellar arteries may help prevent accidents during therapeutic embolization and surgical treatment, as well as misinterpretation

    Anomalous origin of the left coronary artery from the pulmonary artery also recognized as Bland White Garland syndrome is a very rare congenital condition. A two-months old baby boy presented with dyspnoea for two weeks and a pansystolic murmur on auscultation. The base line investigations showed cardiomegaly and bilateral basal haze on X-ray chest. ECG showed ST elevation in leads l and AVl and echocardiography showed situs solitus, levocardia, hypokinetic intraventricular septum, ejection fraction of 30%, mitral regurgitation of grade-I and an anomalous origin of the left coronary artery from pulmonary artery was diagnosed. Patient was in left heart failure. It was rectified surgically by creating a transpulmonary tunnel (Takeuchi repair). Postoperative course was uneventful and he was finally discharged in stable condition. (author)

    Essler, G; Duex, A

    1982-09-01

    In bleeding of oesophageal varices with resistance to common treatment embolisation of the splenic artery causes depression of the portal hypertension by forty per cent. Thrombosis of the splenic or portal vein as in splenectomies are not to be expected. The splenic vein remains open for later spleno-renal anastomosis. By occlusion of the splenic artery we were successful in stopping oesophageal bleeding. In a patient with dominant hypersplenism in portal hypertension the severity of the syndrome decreased after embolisation of the splenic artery. Thrombocytes, leukocytes and gammaglobulin increased.

    Full Text Available The paper presents results of machine learning approach accuracy applied analysis of cardiac activity. The study evaluates the diagnostics possibilities of the arterial hypertension by means of the short-term heart rate variability signals. Two groups were studied: 30 relatively healthy volunteers and 40 patients suffering from the arterial hypertension of II-III degree. The following machine learning approaches were studied: linear and quadratic discriminant analysis, k-nearest neighbors, support vector machine with radial basis, decision trees, and naive Bayes classifier. Moreover, in the study, different methods of feature extraction are analyzed: statistical, spectral, wavelet, and multifractal. All in all, 53 features were investigated. Investigation results show that discriminant analysis achieves the highest classification accuracy. The suggested approach of noncorrelated feature set search achieved higher results than data set based on the principal components.

    Intra-arterial infusion of chemotherapy into the ophthalmic artery for treatment of retinoblastoma has been realized after catheterization of the internal carotid and temporary balloon occlusion beyond the orifice of the ophthalmic artery, or more recently after superselective canulation of the ophthalmic artery by a microcatheter. The superselective catheterization of the ophthalmic artery could be cumbersome because of the implantation of the ostium on the carotid siphon or because of the tortuosity of the carotid siphon. We report our experience of using a retrograde approach through the posterior communicating artery that allows a more direct angle of access to the origin of the ophthalmic artery. (orig.)

  11. Pulmonary arterial hypertension

    2013-01-01

    Pulmonary arterial hypertension (PAH) is a chronic and progressive disease leading to right heart failure and ultimately death if untreated. The first classification of PH was proposed in 1973. In 2008, the fourth World Symposium on PH held in Dana Point (California, USA) revised previous classifications. Currently, PH is devided into five subgroups. Group 1 includes patients suffering from idiopathic or familial PAH with or without germline mutations. Patients with a diagnosis of PAH should systematically been screened regarding to underlying mutations of BMPR2 gene (bone morphogenetic protein receptor type 2) or more rarely of ACVRL1 (activine receptor-like kinase type 1), ENG (endogline) or Smad8 genes. Pulmonary veno occusive disease and pulmonary capillary hemagiomatosis are individualized and designated as clinical group 1'. Group 2 'Pulmonary hypertension due to left heart diseases' is divided into three sub-groups: systolic dysfonction, diastolic dysfonction and valvular dysfonction. Group 3 'Pulmonary hypertension due to respiratory diseases' includes a heterogenous subgroup of respiratory diseases like PH due to pulmonary fibrosis, COPD, lung emphysema or interstitial lung disease for exemple. Group 4 includes chronic thromboembolic pulmonary hypertension without any distinction of proximal or distal forms. Group 5 regroup PH patients with unclear multifactorial mechanisms. Invasive hemodynamic assessment with right heart catheterization is requested to confirm the definite diagnosis of PH showing a resting mean pulmonary artery pressure (mPAP) of ≥ 25 mmHg and a normal pulmonary capillary wedge pressure (PCWP) of ≤ 15 mmHg. The assessment of PCWP may allow the distinction between pre-capillary and post-capillary PH (PCWP > 15 mmHg). Echocardiography is an important tool in the management of patients with underlying suspicion of PH. The European Society of Cardiology and the European Respiratory Society (ESC-ERS) guidelines specify its role

  13. Dark matter detection - III

    Zacek, Viktor

    2015-01-01

    The quest for the missing mass of the universe has become one of the big challenges of todays particle physics and cosmology. Astronomical observations show that only 1% of the matter of the Universe is luminous. Moreover there is now convincing evidence that 85% of all gravitationally observable matter in the Universe is of a new exotic kind, different from the 'ordinary' matter surrounding us. In a series of three lectures we discuss past, recent and future efforts made world- wide to detect and/or decipher the nature of Dark Matter. In Lecture I we review our present knowledge of the Dark Matter content of the Universe and how experimenters search for it's candidates; In Lecture II we discuss so-called 'direct detection' techniques which allow to search for scattering of galactic dark matter particles with detectors in deep-underground laboratories; we discuss the interpretation of experimental results and the challenges posed by different backgrounds; In Lecture III we take a look at the 'indirect detection' of the annihilation of dark matter candidates in astrophysical objects, such as our sun or the center of the Milky Way; In addition we will have a look at efforts to produce Dark Matter particles directly at accelerators and we shall close with a look at alternative nonparticle searches and future prospects.

    2010-01-01

    The complexes of 4-chlorophenoxyacetates of Nd(III), Gd(III) and Ho(III) have been synthesized as polycrystalline hydrated solids, and characterized by elemental analysis, spectroscopy, magnetic studies and also by X-ray diffraction and thermogravimetric measurements. The analysed complexes have the following colours: violet for Nd(III), white for Gd(III) and cream for Ho(III) compounds. The carboxylate groups bind as bidentate chelating (Ho) or bridging ligands (Nd, Gd). On heating to 1173K in air the complexes decompose in several steps. At first, they dehydrate in one step to form anhydrous salts, that next decompose to the oxides of respective metals. The gaseous products of their thermal decomposition in nitrogen were also determined and the magnetic susceptibilities were measured over the temperature range of 76-303K and the magnetic moments were calculated. The results show that 4-chlorophenoxyacetates of Nd(III), Gd(III) and Ho(III) are high-spin complexes with weak ligand fields. The solubility value in water at 293K for analysed 4-chlorophenoxyacetates is in the order of 10 -4 mol/dm 3 . (author)

    Variants and congenital anomalies of the coronary arteries are usually asymptomatic, but may present with severe chest pain or cardiac arrest. The introduction of multidetector CT coronary angiography (MDCT-CA) allows the detection of significant coronary artery stenosis. Improved performance with isotropic spatial resolution and higher temporal resolution provides a valid alternative to conventional coronary angiography (CCA) in many patients. MDCT-CA is now considered the ideal tool for three-dimensional visualization of the complex and tortuous anatomy of the coronary arteries. With multiplanar and volume-rendered reconstructions, MDCT-CA may even outperform CCA in determining the relative position of vessels, thus providing a better view of the coronary vascular anatomy. The purpose of this review is to describe the normal anatomy of the coronary arteries and their main variants based on MDCT-CA with appropriate reconstructions. (orig.)

  19. Venous thromboembolism and arterial complications.

    Prandoni, Paolo; Piovella, Chiara; Pesavento, Raffaele

    2012-04-01

    An increasing body of evidence suggests the likelihood of a link between venous and arterial thrombosis. The two vascular complications share several risk factors, such as age, obesity, smoking, diabetes mellitus, blood hypertension, hypertriglyceridemia, and metabolic syndrome. Moreover, there are many examples of conditions accounting for both venous and arterial thrombosis, such as the antiphospholipid antibody syndrome, hyperhomocysteinemia, malignancies, infections, and the use of hormonal treatment. Finally, several recent studies have consistently shown that patients with venous thromboembolism are at a higher risk of arterial thrombotic complications than matched control individuals. We, therefore, speculate the two vascular complications are simultaneously triggered by biological stimuli responsible for activating coagulation and inflammatory pathways in both the arterial and the venous system. Future studies are needed to clarify the nature of this association, to assess its extent, and to evaluate its implications for clinical practice.

    Treatments for major internal bleeding after injury include permissive hypotension to decrease the rate of blood loss, intravenous infusion of plasma or clotting factors to improve clot formation, and rapid surgical hemostasis or arterial embolization to control bleeding vessels. Yet, little is known regarding major internal arterial hemostasis, or how these commonly used treatments might influence hemostasis. (i) To use a swine model of femoral artery bleeding to understand the perivascular hemostatic response to contained arterial hemorrhage. (ii) To directly confirm the association between hemodynamics and bleeding velocity. (iii) To observe the feasibility of delivering an activated clotting factor directly to internal sites of bleeding using a simplified angiographic approach. Ultrasound was used to measure bleeding velocity and in vivo clot formation by elastography in a swine model of contained femoral artery bleeding with fluid resuscitation. A swine model of internal pelvic and axillary artery hemorrhage was also used to demonstrate the feasibility of local delivery of an activated clotting factor. In this model, clots formed slowly within the peri-wound hematoma, but eventually contained the bleeding. Central hemodynamics correlated positively with bleeding velocity. Infusion of recombinant human activated factor VII into the injured artery near the site of major internal hemorrhage in the pelvis and axillae was feasible. We rediscovered that clot formation within the peri-wound hematoma is an integral component of hemostasis and a feasible target for the treatment of major internal bleeding using activated clotting factors delivered using a simplified angiographic approach. © 2015 International Society on Thrombosis and Haemostasis.

    PurposeThe ‘emborrhoid’ technique consists of the embolization of the hemorrhoidal arteries. The endovascular arterial occlusion is performed using coils placed in the terminal branches of the superior rectal arteries. The emborrhoid technique has been modeled after elective transanal Doppler-guided hemorrhoidal artery ligation which has been shown to be effective in hemorrhoidal disease. We report the first 14 cases of our experience with emborrhoid technique.Materials and MethodsFourteen patients with disabling chronic rectal bleeding were treated using the emborrhoid technique (3 women, 11 men). The stage of the hemorrhoidal disease was II (10 patients), III (3), and IV (1). This treatment was decided by a multidisciplinary team (proctologist, visceral surgeon, and radiologist). Seven patients underwent previous proctological surgery. Ten patients had coagulation disorders (anticoagulants or cirrhosis). Superior rectal arteries were embolized with pushable microcoils (0.018).ResultsTechnical success of the embolization procedure was 100 %. Clinical success at 1 month was 72 % (10/14). Of the 4 patients who experienced rebleeding, two underwent additional embolization of the posterior rectal arteries with success. No pain or ischemic complications were observed in 13 patients. One patient experienced a temporary painful and edematous, perianal reaction.ConclusionOur case studies suggest that coil embolization of the superior rectal arteries is technically feasible, safe and well tolerated. Additional studies are needed to evaluate the efficacy of this new ‘emborrhoid’ technique in the management of hemorrhoidal disease

There is little information regarding arterial elasticity in heart transplant recipients. This study aimed to characterize small (SAE and large (LAE artery elasticity in heart transplant recipients in comparison with an asymptomatic population free of overt cardiovascular disease. A second goal was to identify demographic and clinical factors associated with arterial elasticity in this unique population.Methods: Arterial pulse waveform was registered noninvasively at the radial artery in 71 heart transplant recipients between 2008 and 2010. SAEs and LAEs were derived from diastolic pulse contour analysis. Comparisons were made to a healthy cohort of 1,808 participants selected from our prevention clinic database. Multiple regression analyses were performed to evaluate associations between risk factors and SAE and LAE within the heart transplant recipients.Results: LAE and SAE were significantly lower in heart transplant recipients than in the normal cohort (P <0.01 and P < 0.0001, respectively. Female sex and history of ischemic cardiomyopathy were significantly associated with reduced LAE and SAE. Older age and the presence of moderate cardiac allograft vasculopathy were also significantly associated with reduced SAE. Transplant duration was associated with increased SAE.Conclusion: Heart transplants are associated with peripheral endothelial dysfunction and arterial stiffness, as demonstrated by a significant reduction in SAE and LAE when compared with a

    Diagnosing coronary artery disease is difficult and requires careful consideration of the roles and limitations of the tests used. Standard ECG tests are not reliable indicators of the presence of disease in asymptomatic patients. Thallium stress testing to assess ischemia and exercise ventriculography to assess functional status of the heart are limited in sensitivity and specificity. This is the second of a three-part series on cardiac nuclear medicine. Part I (Med. Instrum., May-June, 1981) focused on the commonly used examinations in cardiac physiology and pathophysiology. Part III will focus on myocardial infarction and other cardiac diseases

  7. Cannabis-associated arterial disease.

    2013-10-01

    The aim of this study was to describe the different arterial complications reported in cannabis smokers. This study was a literature review. Cannabis use was found to be associated with stroke, myocardial infarction, and lower limb arteritis. Arterial disease involved especially young men. There was a very strong temporal link between arterial complications and cannabis use for stroke and myocardial infarction episodes. Patient outcome was closely correlated with cannabis withdrawal and relapses associated with cannabis rechallenge. Cannabis use was associated with particular characteristics of arterial disease. The increased risk of myocardial infarction onset occurred within 1 hour of smoking marijuana compared with periods of non-use. Strokes occurred mainly in the posterior cerebral circulation. Compared with cohorts of thromboangiitis obliterans patients, those with cannabis-associated limb arteritis were younger, more often male, and had more frequent unilateral involvement of the lower limbs at clinical presentation. Cannabis use is associated with arterial disease such as stroke, myocardial infarction, and limbs arteritis. It appears essential to investigate cannabis use in young patients presenting with such arterial manifestations, as outcome is closely correlated with cannabis withdrawal.

Com base nos estudos de Walter Lippann, Agnes Heller, Adam Shaff e Eclea Bosi, pretende-se discutir os conceitos de estereótipo e preconceito, buscando entender o que são e porque se formam. Para entender melhor o estereótipo temos que refletir sobre três elementos que a ele se ligam: a linguagem, o cotidiano e o senso comum. É no plano da linguagem - do diálogo e das práticas de linguagem - que se deve estudar e se pode romper e desconstruir os estereótipos, tomando consciência da própria formação discursiva. O texto oferece, ainda, algumas sugestões para trabalhar o conceito na sala de aula e para ampliar o repertório de textos e referências a serem debatidas com os alunos.

  14. Arterial innervation in development and disease.

    Eichmann, Anne; Brunet, Isabelle

    2014-09-03

    Innervation of arteries by sympathetic nerves is well known to control blood supply to organs. Recent studies have elucidated the mechanisms that regulate the development of arterial innervation and show that in addition to vascular tone, sympathetic nerves may also influence arterial maturation and growth. Understanding sympathetic arterial innervation may lead to new approaches to treat peripheral arterial disease and hypertension.

  15. PREFACE: Quantum Optics III

    Orszag, M.; Retamal, J. C.; Saavedra, C.; Wallentowitz, S.

    2007-06-01

    All the 50 years of conscious pondering did not bring me nearer to an answer to the question `what is light quanta?'. Nowadays, every rascal believes, he knows it, however, he is mistaken. (A Einstein, 1951 in a letter to M Besso) Quantum optics has played a key role in physics in the last several decades. On the other hand, in these early decades of the information age, the flow of information is becoming more and more central to our daily life. Thus, the related fields of quantum information theory as well as Bose-Einstein condensation have acquired tremendous importance in the last couple of decades. In Quantum Optics III, a fusion of these fields appears in a natural way. Quantum Optics III was held in Pucón, Chile, in 27-30 of November, 2006. This beautiful location in the south of Chile is near the lake Villarrica and below the snow covered volcano of the same name. This fantastic environment contributed to a relaxed atmosphere, suitable for informal discussion and for the students to have a chance to meet the key figures in the field. The previous Quantum Optics conferences took place in Santiago, Chile (Quantum Optics I, 2000) and Cozumel, Mexico (Quantum Optics II, 2004). About 115 participants from 19 countries attended and participated in the meeting to discuss a wide variety of topics such as quantum-information processing, experiments related to non-linear optics and squeezing, various aspects of entanglement including its sudden death, correlated twin-photon experiments, light storage, decoherence-free subspaces, Bose-Einstein condensation, discrete Wigner functions and many more. There was a strong Latin-American participation from Argentina, Brazil, Chile, Colombia, Peru, Uruguay, Venezuela and Mexico, as well as from Europe, USA, China, and Australia. New experimental and theoretical results were presented at the conference. In Latin-America a quiet revolution has taken place in the last twenty years. Several groups working in quantum optics and

However, studies of arterial function in vegetarians are limited.Methods: This study investigated arterial function in vegetarianism by comparing 49 healthy postmenopausal vegetarians with 41 age-matched omnivores. The arterial function of the common carotid artery was assessed by carotid duplex, while the pulse dynamics method was used to measure brachial artery distensibility (BAD, compliance (BAC, and resistance (BAR. Fasting blood levels of glucose, lipids, lipoprotein (a, high-sensitivity C-reactive protein, homocysteine, and vitamin B12 were also measured.Results: Vegetarians had significantly lower serum cholesterol, high-density and low-density lipoprotein, and glucose compared with omnivores. They also had lower vitamin B12 but higher homocysteine levels. Serum levels of lipoprotein (a and high-sensitivity C-reactive protein were no different between the two groups. There were no significant differences in carotid beta stiffness index, BAC, and BAD between the two groups even after adjustment for associated covariates. However, BAR was significantly lower in vegetarians than in omnivores. Multiple linear regression analysis revealed that age and pulse pressure were two important determinants of carotid beta stiffness index and BAD. Vegetarianism is not associated with better arterial elasticity.Conclusion: Apparently healthy postmenopausal vegetarians are not significantly better in terms of carotid beta stiffness index, BAC, and BAD, but have significantly decreased BAR than

    We describe a technique to predict preoperatively the safety of permanently occluding an internal carotid artery. The method was performed by imaging stable xenon cerebral blood flow (CBF) with the internal carotid artery both open and temporarily occluded with a nondetachable balloon on a double lumen Swan-Ganz catheter. Patients were those in whom we planned to sacrifice the internal carotid artery (those with giant or inaccessible aneurysms) or those in whom such a sacrifice was at least likely (those with skull base tumors). Patients were divided into three groups on the basis of a comparison of occluded and nonoccluded CBF values. Group-I patients had no significant change in CBF with internal carotid artery occlusion; group-II patients showed a symmetric decrease in CBF; and group-III patients had an asymmetric decrease in CBF, always greater on the occluded side. A fourth group clinically failed to tolerate even brief carotid occlusion. The internal carotid artery in one patients from group III was sacrificed at surgery: the size and shape of his postoperative infarct corresponded almost exactly to the area of asymmetrically decreased CBF on his occluded study. The data suggest that if surgery is likely to result in permanent occlusion of the internal carotid artery, then patients who are at risk for delayed neurologic injury due to a compromised cerebral blood flow should have arterial bypass grafts before such surgery is performed

    2014-01-01

    To investigate variations in superior thyroid artery (STA) based on digital subtraction angiography (DSA). Twenty five angiography studies of 15 pts performed between June 2010 and December 2012 were retrospectively evaluated. These patients underwent DSA of the head and neck region as a part of their superselective neoadjuvant intra-arterial chemotherapy protocol for treatment of laryngeal and hypopharyngeal cancers. Depending upon the location of the tumor, unilateral or bilateral arteriograms of common carotid artery (CCA), external carotid artery (ECA), and STA were performed. Arteriograms were evaluated for the site of origin and branching pattern of STA. STA anatomy was ascribed to one of the three branching patterns. A total of 25 angiograms were evaluated, including 14 right and 11 left. On the right side, STA was noted to arise from ECA in 10 (71.5%), bifurcation of CCA in 3 (21.5%), and CCA in 1 (7%) patient. Left STA was seen to arise from ECA in 8 (72.5%), bifurcation of CCA in 2 (18.5%), and internal carotid artery (ICA) in 1 (9%) patient. Type III branching pattern (non-bifurcation, non-trifurcation) was found to be the most frequent (52%). Infrahyoid branch was found to be the most consistent in terms of its origin from STA. Origin of STA is predictable, arising from ECA in more than 70% cases. Branching pattern of STA, following origin from ECA, is, however, highly variable.

    There are limited therapeutic options for the resolution of digital artery occlusions. Intra-arterial thrombolysis with anticoagulative and thrombolytic drugs successfully restored the blood flow in the affected digital arteries.

  2. Intracranial arterial stenosis.

    Carvalho, Marta; Oliveira, Ana; Azevedo, Elsa; Bastos-Leite, António J

    2014-04-01

    Intracranial arterial stenosis (IAS) is usually attributable to atherosclerosis and corresponds to the most common cause of stroke worldwide. It is very prevalent among African, Asian, and Hispanic populations. Advancing age, systolic hypertension, diabetes mellitus, high levels of low-density lipoprotein cholesterol, and metabolic syndrome are some of its major risk factors. IAS may be associated with transient or definite neurological symptoms or can be clinically asymptomatic. Transcranial Doppler and magnetic resonance angiography are the most frequently used ancillary examinations for screening and follow-up. Computed tomography angiography can either serve as a screening tool for the detection of IAS or increasingly as a confirmatory test approaching the diagnostic accuracy of catheter digital subtraction angiography, which is still considered the gold (confirmation) standard. The risk of stroke in patients with asymptomatic atherosclerotic IAS is low (up to 6% over a mean follow-up period of approximately 2 years), but the annual risk of stroke recurrence in the presence of a symptomatic stenosis may exceed 20% when the degree of luminal narrowing is 70% or more, recently after an ischemic event, and in women. It is a matter of controversy whether there is a specific type of treatment other than medical management (including aggressive control of vascular risk factors and antiplatelet therapy) that may alter the high risk of stroke recurrence among patients with symptomatic IAS. Endovascular treatment has been thought to be helpful in patients who fail to respond to medical treatment alone, but recent data contradict such expectation.

    There is a relationship between the intra-aortic balloon pumping (IABP) benefits and the dynamic behavior of muscular arteries, which is associated with induced changes on the vessel walls through an endothelial-dependent mechanism. The arterial wall elastic behavior is influenced by adventitial function; however, no studies were performed in order to elucidate if this layer plays a role in the changes determined by IABP. Our aim was to quantify acute IABP effects on the mechanical properties of muscular arteries in induced acute heart failure (AHF), before and after adventitia removal. Pressure and diameter were recorded in the iliac arteries (IA) of sheep (n = 7), before and during 1:2 IABP: (i) in control state (CS) with intact IA, (ii) in CS after IA adventitia removal, and (iii) in de-adventitialized IA after AHF. Conduit function, compliance and arterial distensibility were calculated in each state. During CS, IABP resulted in intact IA dilatation and in an increase in conduit function, compliance and distensibility; adventitial removal determined an increase of arterial stiffness with respect to the CS, which decreased when IABP was used; the increase in arterial stiffness observed after adventitia removal was also detected in AHF state; IABP improves conduit function and arterial stiffness in de-adventitialized arteries, both before and during AHF. However, the improvement in these properties was lower than in intact arteries. Before and after AHF induction, the improvements of conduit function and arterial distensibility determined by IABP in intact IA were significantly reduced after adventitia removal. Adventitial layer integrity would be necessary to maximize IABP-related beneficial effects on arterial system properties. © 2013 Wiley Periodicals, Inc. and International Center for Artificial Organs and Transplantation.

  6. Clipping treatment of posterior communicating artery aneurysms associated with arteriosclerosis and calcification: A single center study of 136 cases.

    2018-02-01

    It is widely acknowledged that arteriosclerosis and calcification of the parent artery and aneurysm neck make it difficult to clip posterior communicating artery (PCoA) aneurysms. A total of 136 cases of PCoA aneurysms accompanied by arteriosclerosis and calcification were collected and treated with clipping in the present study. Of the 136 patients, 112 were females (82.4%) and 24 were males (17.6%), with ages ranging from 37 to 76 years (mean age, 60.2 years). Rupture of a PCoA aneurysm was identified in 132 cases (97.1%), and there were 4 cases of unruptured PCoA aneurysms (2.9%). According to the severity of arteriosclerosis and calcification, the aneurysms were divided into type I, II or III. The treatment of type I aneurysms achieved the best curative effect. It is difficult to temporarily occlude type II and III aneurysms during surgery, and temporary occlusion failed in almost 50% of cases. Types II and III were prone to intraoperative aneurysm ruptures. A significantly higher rate of intraoperative aneurysm rupture was seen in type III compared with type II cases. Type II and III cases were more likely to be treated using a fenestrated clip for aneurysm clipping compared with type I cases, and fenestrated clips were used significantly more frequently in type III cases compared with type II cases. Arteriosclerosis and calcification were likely to affect the prognosis of patients, particularly in cases with type III arteriosclerosis and calcification of the parent artery and aneurysm neck. Therefore, the stratification of the arteriosclerosis and calcification of the parent artery and aneurysm neck into types I-III can guide the intraoperative aneurysm clipping strategy, aid in choosing the correct clips, and inform predictions of the occurrence of rupture and hemorrhage, as well as the prognosis for aneurysms.

  7. Primary extracranial vertebral artery aneurysms.

    2013-05-01

    Extracranial vertebral artery aneurysms are uncommon and are usually associated with trauma or dissection. Primary cervical vertebral aneurysms are even rarer and are not well described. The presentation and natural history are unknown and operative management can be difficult. Accessing aneurysms at the skull base can be difficult and, because the frail arteries are often afflicted with connective tissue abnormalities, direct repair can be particularly challenging. We describe the presentation and surgical management of patients with primary extracranial vertebral artery aneurysms. In this study we performed a retrospective, multi-institutional review of patients with primary aneurysms within the extracranial vertebral artery. Between January 2000 and January 2011, 7 patients, aged 12-56 years, were noted to have 9 primary extracranial vertebral artery aneurysms. All had underlying connective tissue or another hereditary disorder, including Ehler-Danlos syndrome (n=3), Marfan's disease (n=2), neurofibromatosis (n=1), and an unspecified connective tissue abnormality (n=1). Eight of 9 aneurysms were managed operatively, including an attempted bypass that ultimately required vertebral ligation; the contralateral aneurysm on this patient has not been treated. Open interventions included vertebral bypass with vein, external carotid autograft, and vertebral transposition to the internal carotid artery. Special techniques were used for handling the anastomoses in patients with Ehler-Danlos syndrome. Although endovascular exclusion was not performed in isolation, 2 hybrid procedures were performed. There were no instances of perioperative stroke or death. Primary extracranial vertebral artery aneurysms are rare and occur in patients with hereditary disorders. Operative intervention is warranted in symptomatic patients. Exclusion and reconstruction may be performed with open and hybrid techniques with low morbidity and mortality.

  8. Branches of the Facial Artery.

    Hwang, Kun; Lee, Geun In; Park, Hye Jin

    2015-06-01

    The aim of this study is to review the name of the branches, to review the classification of the branching pattern, and to clarify a presence percentage of each branch of the facial artery, systematically. In a PubMed search, the search terms "facial," AND "artery," AND "classification OR variant OR pattern" were used. The IBM SPSS Statistics 20 system was used for statistical analysis. Among the 500 titles, 18 articles were selected and reviewed systematically. Most of the articles focused on "classification" according to the "terminal branch." Several authors classified the facial artery according to their terminal branches. Most of them, however, did not describe the definition of "terminal branch." There were confusions within the classifications. When the inferior labial artery was absent, 3 different types were used. The "alar branch" or "nasal branch" was used instead of the "lateral nasal branch." The angular branch was used to refer to several different branches. The presence as a percentage of each branch according to the branches in Gray's Anatomy (premasseteric, inferior labial, superior labial, lateral nasal, and angular) varied. No branch was used with 100% consistency. The superior labial branch was most frequently cited (95.7%, 382 arteries in 399 hemifaces). The angular branch (53.9%, 219 arteries in 406 hemifaces) and the premasseteric branch were least frequently cited (53.8%, 43 arteries in 80 hemifaces). There were significant differences among each of the 5 branches (P < 0.05) except between the angular branch and the premasseteric branch and between the superior labial branch and the inferior labial branch. The authors believe identifying the presence percentage of each branch will be helpful for surgical procedures.

    2014-01-01

    After the Basel Committee on Banking Supervision (BCBS) introduced the Basel III framework in 2010, individual countries confronted the question of how best to implement the framework given their unique circumstances. Switzerland, with a banking industry that is both heavily concentrated and very large relative to the size of its overall economy, faced a special challenge. It ultimately adopted what is sometimes referred to as the “Swiss Finish” to Basel III – enhanced requirements applicable...

  10. Aortic Branch Artery Pseudoaneurysms Associated with Intramural Hematoma: When and How to Do Endovascular Embolization

    To describe when and how to perform endovascular embolization of aortic branch artery pseudoaneurysms associated with type A and type B intramural hematoma (IMH) involving the descending thoracic and abdominal aorta (DeBakey I and III) that increased significantly in size during follow-up. Sixty-one patients (39 men; mean {+-} standard deviation age 66.1 {+-} 11.2 years) with acute IMH undergoing at least two multidetector computed tomographic examinations during follow-up for 12 months or longer were enrolled. Overall, 48 patients (31 men, age 65.9 {+-} 11.5) had type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III). Among the 48 patients, 26 (54 %; 17 men, aged 64.3 {+-} 11.4 years) had 71 aortic branch artery pseudoaneurysms. Overall, during a mean follow-up of 22.1 {+-} 9.5 months (range 12-42 months), 31 (44 %) pseudoaneurysms disappeared; 22 (31 %) decreased in size; two (3 %) remained stable; and 16 (22 %) increased in size. Among the 16 pseudoaneurysms with increasing size, five of these (three intercostal arteries, one combined intercostobronchial/intercostal arteries, one renal artery), present in five symptomatic patients, had a significant increase in size (thickness >10 mm; width and length >20 mm). These five patients underwent endovascular embolization with coils and/or Amplatzer Vascular Plug. In all patients, complete thrombosis and exclusion of aortic pseudoaneurysm and relief of back pain were achieved. Aortic branch artery pseudoaneurysms associated with type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III) may be considered relatively benign lesions. However, a small number may grow in size or extend longitudinally with clinical symptoms during follow-up, and in these cases, endovascular embolization can be an effective and safe procedure.

    2006-01-01

    Purpose: To evaluate the hemodynamic changes in the extraocular orbital vessels of the patients with chronic obstructive pulmonary disease (COPD), using color Doppler ultrasonography (CDU) technique, and to compare the results with those of healthy control subjects. Methods: Forty-five patients with COPD and 17 healthy control subjects were included in this study. Patients with COPD were classified according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Fifteen patients of stage I COPD (mild airflow limitation), stage II COPD (worsening airflow limitation) or stage III COPD (severe airflow limitation) were enrolled into Group I, II and III, respectively. End tidal carbon dioxide (EtCO 2 ), peripheral oxygen saturation (SpO 2 ), pulse rate (PR) and respiratory rate (RR) were measured by using capnograph/pulse oximeter in all patients. Measurements were performed in only one randomly chosen eye of each participant. The peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistance index (RI) were measured in the ophthalmic artery (OA), central retinal artery (CRA), lateral short posterior ciliary artery (LPCA) and medial short posterior ciliary artery (MPCA), using CDU technique. Results: The PSV measurements of the OA were significantly higher in Groups II and III compared to control group (p 2 with PSV (r = 0.53, p < 0.01) and EDV (r = 0.51, p < 0.01) of the OA. Statistically significant correlations were also found for the SpO2 with RI (r = -0.34, p < 0.05) in the OA. Conclusion: We concluded that COPD is associated with impaired retrobulbar hemodynamics, especially in the ophthalmic artery. Moreover, central retinal and posterior ciliary arteries with increased resistance are also found to be affected when compared with healthy control eyes

    Tyrosinaemia type III is a rare disorder caused by a deficiency of 4-hydroxyphenylpyruvate dioxygenase, the second enzyme in the catabolic pathway of tyrosine. The majority of the nine previously reported patients have presented with neurological symptoms after the neonatal period, while others detected by neonatal screening have been asymptomatic. All have had normal liver and renal function and none has skin or eye abnormalities. A further four patients with tyrosinaemia type III are described. It is not clear whether a strict low tyrosine diet alters the natural history of tyrosinaemia type III, although there remains a suspicion that treatment may be important, at least in infancy.

  13. Thermodecomposition of lanthanides (III) and ytrium (III) glucoheptonates

    Giolito, J.

    1987-01-01

    The lanthanides (III) and yttrium (III) glucoheptonates as well the D-glucoheptono 1-4 lactone were studied using common analytical methods, elemental microanalysis of carbon and hydrogen, thermogravimetry and differential scanning calorimetry. These compounds were prepared from the reaction between the lanthanides (III) and yttrium (III) hydroxides and glucoheptonic acid aqueous solution obtained by means of the delta lactone hydrolysis of this acid. After stoichiometric reaction the compounds were precipitated by the addition of absolute ethanol, washed with the same solvent and dried in desiccator. Thermogravimetric the (TG) curves of the lanthanides glucoheptonates of the ceric group present thermal profiles with enough differences permitting an easy caracterization of each compound and the yttrium (III) glucoheptonate TG curve showed a great similarity with the erbium (III) compound TG curve. The differential scanning calometry (DSC) curves showed endothermic and exothermic peaks by their shape, height and position (temperature) permit an easy and rapid identification of each compound specially if DSC and TG curves were examined simultaneously.

    2018-04-27

    We encountered a case of duplicated right vertebral artery during an anatomical dissection course for medical students in 2015. Two vertebral arteries were found in the right neck of a 91-year-old female cadaver. The proximal leg of the arteries arose from the area between the right subclavian artery and the right common carotid artery that diverged from the brachiocephalic artery. The distal leg arose from the right subclavian artery as expected. The proximal leg entered the transverse foramen of the fourth cervical vertebra and the distal leg entered the transverse foramen of the sixth cervical vertebra. The two right vertebral arteries joined to form one artery just after the origin of the right vertebral artery of the brachiocephalic artery entered the transverse foramen of the fourth cervical vertebra. This artery then traveled up in the transverse foramina and became the basilar artery, joining with the left vertebral artery. We discuss the embryological origin of this case and review previously reported cases.

  16. Anomalous right coronary artery arising from the pulmonary artery and constrictive pericarditis: an unusual association

    Silvestre, Odilson Marcos; Adam, Eduardo Leal; de Melo, Dirceu Thiago Pessoa; Dias, Ricardo Ribeiro; Ramires, Felix J. A.; Mady, Charles

    2013-01-01

    ABSTRACT The association of anomalous right coronary artery originating from the pulmonary artery and constrictive pericarditis has never been showed in the literature. We present the first case of this unusual association in a patient with right heart failure. After diagnosis, the patient was referred to surgery and underwent phrenic-to-phrenic pericardiectomy; graft implant of right internal thoracic artery to right coronary artery; and ligation of the anomalous origin of the right coronary artery from the pulmonary artery. Such procedures solved the potential risk of sudden death related to anomalous right coronary artery originating from the pulmonary artery and alleviated the symptoms of heart failure caused by constrictive pericarditis.

    The aim of this study was to measure the area of the coronary ostia, assess their localization in the coronary sinuses and to determine the morphology of the stem of the left and right coronary arteries in the domestic shorthair cat. The study was conducted on 100 hearts of domestic shorthair cats of both sexes, aged 2–18 years, with an average body weight of 4.05 kg. A morphometric analysis of the coronary ostia was carried out on 52 hearts. The remaining 48 hearts were injected with a casting material in order to carry out a morphological assessment of the left and right coronary arteries. In all the studied animals, the surface of the left coronary artery ostium was larger than the surface of the right coronary artery ostium. There were four types of the left main coronary artery: type I (23 animals, 49%)–double-branched left main stem (giving off the left circumflex branch and the interventricular paraconal branch, which in turn gave off the septal branch), type II (12 animals, 26%)–double-branched left main stem (giving off the left circumflex branch and the interventricular paraconal branch without the septal branch), type III (11 animals, 23%)–triple-branched left main stem (giving off the left circumflex branch, interventricular branch and the septal branch, type IV (1 animal, 2%)–double-branched left main stem (giving off the interventricular paraconal branch and the left circumflex branch, which in turn gave off the septal branch). The left coronary artery ostium is greater than the right one. There is considerable diversity in the branches of proximal segment of the left coronary artery, while the right coronary artery is more conservative. These results can be useful in defining the optimal strategies in the endovascular procedures involving the coronary arteries or the aortic valve in the domestic shorthair cat. PMID:29020103

    The clinical spectrum of internal carotid artery occlusion ranges from being a completely asymptomatic occlusion to a devastating stroke or death. The prevalence of asymptomatic internal carotid artery occlusion is unknown, particularly for bilateral occlusion. The distal branches of the external carotid artery anastomose with distal branches of the internal carotid artery provide important sources of collateral circulation to the brain. Stenosis of the external carotid artery with ipsilateral/bilateral internal occlusion may result in ischemic sequelae. Coiling or kinking of the vertebral artery is a rare morphological entity that is infrequently reported because it remains asymptomatic and has no clinical relevance. Currently, there is little evidence to support management strategies for this disease entity and no official recommendations for asymptomatic bilateral carotid artery occlusion. We present a case of a 62-year-old female with asymptomatic bilateral internal carotid artery occlusion, bilateral external carotid artery stenoses, and bilateral kinking of the vertebral artery at the V2 segment, who has been successfully managed conservatively for over 5 years. An individualized approach to management of patients with bilateral internal carotid artery occlusion, especially in combination with external carotid artery stenosis and elongation malformations of the vertebral artery is key to a successful strategy.

  1. Intra-arterial digital subtraction angiography of the carotid arteries

    Nakstad, P.; Bakke, S.J.; Kjartansson, O.; Nyhus, S.

    1986-01-01

    A cross-over test in intra-arterial digital subtraction angiography (IADSA) of the carotid arteries was performed in 50 patients to evaluate image quality and side-effects with iohexol and metrizoate injected at concentrations of 100 mg I/ml by hand. The image quality was excellent or good in all cases. Although the severity and the frequency of side-effects were higher with metrizoate, both contrast media were suitable for IADSA at this low concentration. No complications were seen. It was assumed that the risk with IADSA was less than that of conventional-selectivity and with small amounts of contrast media, as in this study. (orig.)

    2008-01-01

    This paper illustrates examples of popliteal artery pathologies imaged with contrast enhanced magnetic resonance angiography (CE-MRA) and magnetic resonance imaging (MRI) at a single tertiary referral centre. Popliteal artery pathologies were identified in 1710 patients referred over a 6-year period with symptoms suggesting lower limb arterial occlusive disease. Common pathologies such as atherosclerotic occlusive disease, thromboemboli and aneurysm disease are discussed as well as unusual pathologies such as cystic adventitial disease, mycotic aneurysm and arterial entrapment. The combination of CE-MRA and the excellent soft tissue resolution of MRI allow detailed evaluation of arterial and peri-arterial pathologies, and facilitate appropriate management decisions

    There are no reliable blood biomarkers to detect early lung cancer. We used a novel strategy that allows discovery of differentially present proteins against a complex and variable background. Mass spectrometry analyses of paired pulmonary venous-radial arterial blood from 16 lung cancer patients were applied to identify plasma proteins potentially derived from the tumor microenvironment. Two differentially expressed proteins were confirmed in 64 paired venous-arterial blood samples using an immunoassay. Twenty-eight pre- and postsurgical resection peripheral blood samples and two independent, blinded sets of plasma from 149 participants in a lung cancer screening study (49 lung cancers and 100 controls) and 266 participants from the National Heart Lung and Blood Institute Lung Health Study (45 lung cancer and 221 matched controls) determined the accuracy of the two protein markers to detect subclinical lung cancer. Connective tissue-activating peptide III (CTAP III)/ neutrophil activating protein-2 (NAP-2) and haptoglobin were identified to be significantly higher in venous than in arterial blood. CTAP III/NAP-2 levels decreased after tumor resection (P = .01). In two independent population cohorts, CTAP III/NAP-2 was significantly associated with lung cancer and improved the accuracy of a lung cancer risk prediction model that included age, smoking, lung function (FEV(1)), and an interaction term between FEV(1) and CTAP III/NAP-2 (area under the curve, 0.84; 95% CI, 0.77 to 0.91) compared to CAPIII/NAP-2 alone. We identified CTAP III/NAP-2 as a novel biomarker to detect preclinical lung cancer. The study underscores the importance of applying blood biomarkers as part of a multimodal lung cancer risk prediction model instead of as stand-alone tests.

    Seven patients with thrombotic occlusions of the peripheral arteries or grafts were treated with urokinase by direct intraarterial selective infusion. During the infusion, simultaneous heparin infusion was used to reduce the frequency of thrombus formation on the infusion catheter or recurrent thrombosis. In 4 patients in whom a complete thrombolysis occurred, urokinase was infused by a high-dose transthrombus bolus technique followed by continuous infusion. There other patients, in whom thrombolysis was partially accomplished and then surgical thrombectomy was performed, were treated only by continuous urokinase infusion. Small hematomas developed at the infusion catheter entry site in 2 patients, but transfusion or operation was not required. Other significant complications were not found. Our results suggest that selective arterial infusion of urokinase with a transthrombus bolus technique can accomplish a complete arterial thrombolysis without any significant complications.

  10. Bronchial arteries: anatomy, function, hypertrophy, and anomalies.

    Walker, Christopher M; Rosado-de-Christenson, Melissa L; Martínez-Jiménez, Santiago; Kunin, Jeffrey R; Wible, Brandt C

    2015-01-01

    The two main sources of blood supply to the lungs and their supporting structures are the pulmonary and bronchial arteries. The bronchial arteries account for 1% of the cardiac output but can be recruited to provide additional systemic circulation to the lungs in various acquired and congenital thoracic disorders. An understanding of bronchial artery anatomy and function is important in the identification of bronchial artery dilatation and anomalies and the formulation of an appropriate differential diagnosis. Visualization of dilated bronchial arteries at imaging should alert the radiologist to obstructive disorders that affect the pulmonary circulation and prompt the exclusion of diseases that produce or are associated with pulmonary artery obstruction, including chronic infectious and/or inflammatory processes, chronic thromboembolic disease, and congenital anomalies of the thorax (eg, proximal interruption of the pulmonary artery). Conotruncal abnormalities, such as pulmonary atresia with ventricular septal defect, are associated with systemic pulmonary supply provided by aortic branches known as major aortopulmonary collaterals, which originate in the region of the bronchial arteries. Bronchial artery malformation is a rare left-to-right or left-to-left shunt characterized by an anomalous connection between a bronchial artery and a pulmonary artery or a pulmonary vein, respectively. Bronchial artery interventions can be used successfully in the treatment of hemoptysis, with a low risk of adverse events. Multidetector computed tomography helps provide a vascular road map for the interventional radiologist before bronchial artery embolization. RSNA, 2015

    2012-09-01

    Full Text Available Prevalence of coronary artery disease (CAD has increased with the expansion of life span among the elderly population in the world. Hence, the issue of the coronary artery bypass in octogenarians has attracted more attention. Recent literature about the topic revealed nearly the same excellent results as those in the younger population under the newly developed operative techniques and improving concept in perioperative management and postoperative care. In this article, we review the current status of the procedure that was thought to be dangerous in the earlier era, including its risk factors, result, and benefit.

  16. [Atherectomy for peripheral arterial disease].

    Londero, Louise Skovgaard; Høgh, Annette Langager; Lindholt, Jes Sanddal

    2015-04-13

    Symptomatic peripheral arterial disease is managed according to national and international guidelines and the number of vascular reconstructions performed each year has increased over the past decade mainly due to an increasing frequency of endovascular procedures. Atherectomy as an alternative to the established treatment of symptomatic peripheral arterial disease has recently been analysed in a Cochrane review. In Denmark, atherectomy is not performed and so far the evidence is poor as the method is not an alternative to the established treatment in this country.

  17. Management of coronary artery disease

    Safri, Z.

    2018-03-01

    Coronary Artery Disease (CAD) is associated with significant morbidity and mortality, therefore it’s important to early and accurate detection and appropriate management. Diagnosis of CAD include clinical examination, noninvasive techniques such as biochemical testing, a resting ECG, possibly ambulatory ECG monitoring, resting echocardiography, chest X-ray in selected patients; and catheterization. Managements of CAD patients include lifestyle modification, control of CAD risk factors, pharmacologic therapy, and patient education. Revascularization consists of percutaneous coronary angioplasty and coronary artery bypass grafting. Cardiac rehabilitation should be considered in all patients with CAD. This comprehensive review highlights strategies of management in patients with CAD.

  18. Sphenopalatine artery ligation: technical note.

    Pothier, David D; Mackeith, Samuel; Youngs, Robin

    2005-10-01

    Epistaxis is a common problem. Most patients presenting to hospital will stop bleeding with simple first-aid measures or with nasal packing. Those who do not stop will usually require surgical management. For persistent posterior epistaxis, the sphenopalatine artery may be ligated as the artery leaves the sphenopalatine foramen to enter the nasal mucosa of the lateral wall of the nose. This may be performed endoscopically. We describe the anatomy of the area and the surgical technique. We also present a brief review of the literature on this technique.

    Full Text Available A traça Phthorimaea operculella (Zeller é considerada atualmente uma das principais pragas da batata. O uso de resistência varietal para controle desse inseto é uma alternativa promissora, mas que ainda precisa ser melhor pesquisada. A resistência de genótipos de batata à traça foi avaliada, em condições de laboratório, analisando-se o efeito de folhas e tubérculos sobre a biologia do inseto. Comparou-se também o desenvolvimento da traça em folhas de batata e tomate. Os experimentos foram conduzidos com os clones de batata NYL 235-4 e N 140-201 (ambos com tricomas glandulares tipo A nas folhas, as cultivares Aracy, Apuã e Itararé e a cultivar de tomate Santa Clara. Os insetos foram criados em folíolos e tubérculos dos genótipos, avaliando-se a duração e a viabilidade das fases larval e pupal e o peso de pupas. O desenvolvimento do inseto não foi afetado nas folhas dos genótipos de batata, mesmo nos materiais com tricomas glandulares. Entretanto, em folhas de tomate houve aumento do período larval e diminuição do peso de pupas, sendo este substrato menos favorável ao desenvolvimento da traça quando comparado às folhas de batata. Em testes com tubérculos, o clone NYL 235-4 apresentou resistência a P. operculella, provocando redução significativa na viabilidade larval e alongamento desta fase. O clone N 140-201 afetou o desenvolvimento do inseto de forma menos pronunciada, alongando a fase larval.

    Peripheral arterial disease is a major health problem and there is a significant need to develop therapies to prevent its progression to claudication and critical limb ischemia. Promising results in rodent models of arterial occlusion have generally failed to predict clinical success and led to questions of their relevance. While sub-optimal models may have contributed to the lack of progress, we suggest that advancement has also been hindered by misconceptions of the human capacity for compensation and the specific vessels which are of primary importance. We present and summarize new and existing data from humans, Ossabaw miniature pigs, and rodents which provide compelling evidence that natural compensation to occlusion of a major artery (i) may completely restore perfusion, (ii) occurs in specific pre-existing small arteries, rather than the distal vasculature, via mechanisms involving flow-mediated dilation and remodeling (iii) is impaired by cardiovascular risk factors which suppress the flow-mediated mechanisms and (iv) can be restored by reversal of endothelial dysfunction. We propose that restoration of the capacity for flow-mediated dilation and remodeling in small arteries represents a largely unexplored potential therapeutic opportunity to enhance compensation for major arterial occlusion and prevent the progression to critical limb ischemia in the peripheral circulation.

    Analysis, evaluation and classification of hepatic arterial supply variants and determination of their frequency distribution in CT-angiographies. CT-angiographies of 1,568 patients were evaluated retrospectively for the period between January 1, 2010 and August 30, 2012. The hepatic arterial anatomy was assessed and categorized according to Michels's classification. So far unclassified variants were considered separately. Results: CT-angiographies of 1297 patients were included in the study. Type I according to Michels was seen in 937 cases (72.2%), followed by type V in 114 patients (8.8%) and type III in 83 patients (6.4%). Type X could not be found in any of the patients. Not yet classified variants were discovered in 26 patients. The most frequent variant in this connection was a right hepatic artery originating from the superior mesenteric artery with the left hepatic artery originating from the left gastric artery (n=10). Michels's classification could be largely confirmed on the basis of a radiologically examined patient population. Not yet classified variants were categorized into subgroups of the existing classification.

    2002-12-01

    Full Text Available Este artículo presenta un modelo de tipo de cambio real siguiendo los desarrollos de la escuela neokeynesiana. Se estima econométricamente de acuerdo con la metodología de la escuela inglesa de econometría. El modelo empírico incorpora una dinámica interesante y respeta las restricciones de equilibrio de largo plazo entre el tipo de cambio real y los fundamentales macroeconómicos. Se encuentra que el ritmo de apreciación o depreciación del tipo de cambio real está determinado por los cambios en los términos de intercambio, la apertura de la economía, los flujos de capitales y la aceleración de la devaluación nominal. El incremento del gasto público no es significativo a los niveles convencionales de confianza estadística. Finalmente se evalúa si la devaluación cumple con los requisitos de exogeneidad débil, exogeneidad fuerte y superexogeneidad.

  11. Tipos de tirano y resistencia en Francisco Suárez

    Pablo Font Oporto

    2017-09-01

    Full Text Available El presente artículo pretende analizar la discusión que Francisco Suárez mantiene con las tesis contrarias a la distinción entre tipos de tirano en la cuestión del tiranicidio (Defensio fidei, Libro VI, capítulo IV, números 10-13. Para esta visión no le es lícito a una persona privada matar a ninguno de los dos tipos de tirano; sólo es posible darles muerte en legítima defensa, porque se entiende que en tal caso se actúa en ejercicio de autoridad pública. Suárez acaba admitiendo esta tesis en el número 13, lo que parece contradecirse con lo sostenido en el número 7, donde se aceptaba la muerte del usurpador por cualquier particular. Sin embargo, en el fondo mantiene la diferencia entre ambos tipos de tirano, por cuanto que en el caso del usurpador sostiene que siempre se dan las condiciones para alegar legítima defensa. Queda sin aclarar qué ocurre en tal caso con las condiciones dispuestas en los números 8 y 9.

    Full Text Available Congenital absence of left circumflex artery is a rare congenitalanomaly of the coronary arteries. The prevalence of theanomaly in different studies ranges from 0.6% to 1.3%. Ofthese, 80% are benign and asymptomatic and 20% are clinicallyimportant. We report a 56-year-old man presented withacute resting chest pain who was diagnosed as having acuteanterolateral infarction accompanied by electrocardiographicchanges and elevated cardiac enzymes. Coronary angiographyin different views was conducted, however, no left circumflexartery was found. The territory supplied by the artery had beenperfused by the super dominant right coronary artery. Therewas no left circumflex coronary artery with anomalous origin.Sever stenosis of left anterior ascending artery superimposedto the absent left circumflex artery was presented as acute anterolateralinfarction. Although absence of the artery is mostlyconsidered as a benign condition, atherosclerotic lesions maybe more important in such cases because of diminished compensatingmechanisms.

    Full Text Available La diabetes mellitus tipo 2 es una enfermedad metabólica crónica, frecuente y progresiva, responsable del 90% de los casos de diabetes a nivel mundial. Aproximadamente el 60% de los individuos que padecen este desorden no alcanzan niveles óptimos de hemoglobina glicosilada, a pesar de la disponibilidad de numerosas alternativas terapéuticas. Los dos objetivos más importantes a cumplir en el manejo actual de la diabetes tipo 2 son la capacidad de los agentes antidiabéticos de exhibir eficacia prolongada y la capacidad de preservar la función de las células beta pancreáticas. El efecto incretina se encuentra reducido en pacientes con diabetes tipo 2. Exenatida pertenece a un nuevo grupo de drogas antidiabéticas que mejoran el control de la glucemia en estos pacientes a través de mecanismos fisiológicos glucorregulatorios que mejoran el efecto incretina. Los ensayos clínicos fase III con exenatida demostraron una reducción media de aproximadamente el 1% en los valores de hemoglobina glicosilada. Los datos a largo plazo de estudios de extensión no controlados indican una mejoría sostenida en los niveles de hemoglobina glicosilada y una reducción progresiva del peso luego de 3 años de tratamiento con esta droga. La droga es generalmente bien tolerada y los efectos adversos más frecuentes son los gastrointestinales, con una intensidad leve a moderada. El objetivo de esta revisión es analizar la evidencia publicada hasta la fecha sobre la eficacia y tolerabilidad del tratamiento con exenatida y su rol en el tratamiento de la diabetes tipo 2.Type 2 diabetes mellitus is a common, chronic and progressive metabolic disorder, which accounts for 90% of diabetes cases worldwide. Approximately 60% of individuals with the disease do not achieve target glycosylated hemoglobin levels, despite the availability of many antidiabetic agents. The two most important needs in the present management of diabetes are the ability of antidiabetic agents

    Persistent stapedial artery is a rare congenital anomaly that occurs by a failure in the involution of such artery. Most patients with persistent stapedial artery are asymptomatic. The imaging diagnosis is made principally by means of multidetector computed tomography. In the present case, persistent stapedial artery was an incidental computed tomography finding. The authors discuss the embryogenesis, computed tomography findings and the importance of an early diagnosis of such anomaly. (author)

    2013-10-01

    The arterial vascularization of the pineal gland (PG) remains a debatable subject. This study aims to provide detailed information about the arterial vascularization of the PG. Thirty adult human brains were obtained from routine autopsies. Cerebral arteries were separately cannulated and injected with colored latex. The dissections were carried out using a surgical microscope. The diameters of the branches supplying the PG at their origin and vascularization areas of the branches of the arteries were investigated. The main artery of the PG was the lateral pineal artery, and it originated from the posterior circulation. The other arteries included the medial pineal artery from the posterior circulation and the rostral pineal artery mainly from the anterior circulation. Posteromedial choroidal artery was an important artery that branched to the PG. The arterial supply to the PG was studied comprehensively considering the debate and inadequacy of previously published studies on this issue available in the literature. This anatomical knowledge may be helpful for surgical treatment of pathologies of the PG, especially in children who develop more pathology in this region than adults.

    Full Text Available O circuito arterial do encéfalo é de grande importância, pois é responsável pela vascularização do encéfalo, sendo este o principal órgão do sistema nervoso central e responsável por receber e processar informações. A espécie estudada foi escolhida por tratar-se de um mamífero pertencente à ordem Xenarthra e os integrantes dessa ordem são pouco estudados, devido à dificuldade de acesso a esses animais. Para desenvolver este trabalho, foram estudados cinco espécimes de Tamanduá-mirim (Tamandua tetradactyla. O material teve o sistema arterial injetado com látex Neoprene 650, corado em vermelho e fixado em solução aquosa de Formaldeído 10%, sendo posteriormente dissecados para sistematização dos vasos. O circuito arterial da base do encéfalo do tamanduá-mirim circunda o corpo mamilar, a fossa interpenduncular, o túber cinéreo, a hipófise e o quiasma óptico. A porção rostral desse circuito é caracterizada pelos ramos rostrais das artérias carótidas internas e a porção caudal é constituída pelas artérias comunicantes caudais e ramos caudais da artéria carótida interna. Esta espécie animal apresenta o tipo II de irrigação encefálica no qual existe a participação das artérias carótidas internas e do sistema vértebro-basilar para a formação do circuito arterial.The arterial circuit of the brain is of great importance because it is responsible for vascularization of the brain and this is the main organ of the central nervous system and responsible for receiving and processing information.

  11. Basilar artery angulation and vertigo due to the hemodynamic effect of dominant vertebral artery.

    Cosar, Murat; Yaman, Mehmet; Eser, Olcay; Songur, Ahmet; Ozen, Oguz A

    2008-01-01

    Vertebral arteries form the basilar artery at the pontobulbar junction. The vertebral artery may have dominancy in one of them. The branches of basilar arteries supply blood for the vestibular nuclei and its connections. Vertigo is seen generally in the upper middle aged patients. Vertigo can be observed in dolichoectasia of basilar artery such as angulation and elongation, because of the diminished blood supply and changed hemodynamic factors of vestibular nuclei and its connections. We hypothesized that angulation or elongation of basilar artery can be estimated according to the unilateral vertebral artery dominant hypertensive patients. The basilar artery can angulate from the dominant side of vertebral artery to the recessive side. These angulation and elongation can effect the hemodynamic factors in absence of growing collateral arteries. So, the vertigo attacks may occur in these patients.

    Two angiographic instances of anomalous external carotid artery (ECA) and internal carotid artery (ICA) anastomosis are described, each occurring at the C2-3 level and bearing remnants of proximal ICA. The ICA remnant of one patient (identifiable immediately upon bifurcation of the common carotid artery) was hypoplastic, and that of the other patient was an occluded arterial stump. These features are not typical of non-bifurcating ICA. The occipital artery originated from an anomalous connection in one instance and from the main trunk of the ECA (just past the ECA-ICA connection) in the other.

    2016-07-01

    Full Text Available Objective: This study aims to determine changes in the proportions of types I and III collagen in hemorrhoids and to verify the sliding anal canal lining theory. Patients and method: The study is focused on a sample of 17 patients, 9 females and 8 males (age range: 30–70 years, with grade III and grade IV hemorrhoids. Tissue from 4 fetuses (age: 16 weeks of gestation was used as control sample. All the participants gave their informed consent. Samples were gathered in 2014. All patients underwent open hemorrhoidectomy by using the technique described by Milligan and Morgan, published in Lancet journal in 1937. The hemorrhoid samples were stained with hematoxylin–eosin for the histologic study to confirm the hemorrhoidal tissue diagnosis. The picrosirius red staining protocol was used after the histologic analysis. The method used for image processing is described in the text. Images were imported to the Image Tool for Windows software. The same process was used on the embryonic tissue. Data resulting from the analysis of images were processed using STATISTICA, a software for statistical analysis. Results: When compared, it was found that the two tissues presented very different values, with hemorrhoids containing the highest type III collagen values. Conclusion: Our results seem to imply that hemorrhoids have a larger proportion of type III collagen than fetal tissue. They also suggest a possible age-related deterioration of the tissue.

    Intravascular stents are being used with increasing frequency in interventional neuroradiology. Iatrogenic arterial rupture is an uncommon but serious complication. We present a case of arterial rupture and subarachnoid haemorrhage during middle cerebral artery stenting, treated by emergency additional, overlapping stenting and balloon tamponade of the dissected vessel. Thrombotic occlusion of the artery was managed by intra-arterial abciximab. Normal vessel patency was re-established within 20 min and the patient recovered with no neurological deficit. (orig.)

  17. Missed Total Occlusion Due to the Occipital Artery Arising from the Internal Carotid Artery

    Ustunsoz, Bahri; Gumus, Burcak; Koksal, Ali; Koroglu, Mert; Akhan, Okan

    2007-01-01

    A 56-year-old man was referred for digital subtraction angiography (DSA) with an ultrasound diagnosis of right proximal internal carotid artery (ICA) stenosis for possible carotid artery stenting. DSA revealed total occlusion of the ICA and an occipital artery arising from the stump and simulating continuation of the ICA. An ascending pharyngeal artery also arose from the same occipital artery. This case is of interest because this is a rare variation besides being a cause of misdiagnosis at carotid ultrasound

  18. Plasma viscosity increase with progression of peripheral arterial atherosclerotic disease.

    Poredos, P; Zizek, B

    1996-03-01

    Increased blood and plasma viscosity has been described in patients with coronary and peripheral arterial disease. However, the relation of viscosity to the extent of arterial wall deterioration--the most important determinant of clinical manifestation and prognosis of the disease--is not well known. Therefore, the authors studied plasma viscosity as one of the major determinants of blood viscosity in patients with different stages of arterial disease of lower limbs (according to Fontaine) and its relation to the presence of some risk factors of atherosclerosis. The study encompassed four groups of subjects: 19 healthy volunteers (group A), 18 patients with intermittent claudication up to 200 m (stage II; group B), 15 patients with critical ischemia of lower limbs (stage III and IV; group C), and 16 patients with recanalization procedures on peripheral arteries. Venous blood samples were collected from an antecubital vein without stasis for the determination of plasma viscosity (with a rotational capillary microviscometer, PAAR), fibrinogen, total cholesterol, alpha-2-macroglobulin, and glucose concentrations. In patients with recanalization procedure local plasma viscosity was also determined from blood samples taken from a vein on the dorsum of the foot. Plasma viscosity was most significantly elevated in the patients with critical ischemia (1.78 mPa.sec) and was significantly higher than in the claudicants (1.68 mPa.sec), and the claudicants also had significantly higher viscosity than the controls (1.58 mPa.sec). In patients in whom a recanalization procedure was performed, no differences in systemic and local plasma viscosity were detected, neither before nor after recanalization of the diseased artery. In all groups plasma viscosity was correlated with fibrinogen concentration (r=0.70, P < 0.01) and total cholesterol concentration (r=0.24, P < 0.05), but in group C (critical ischemia) plasma viscosity was most closely linked to the concentration of alpha-2

  19. Dicer activity in neural crest cells is essential for craniofacial organogenesis and pharyngeal arch artery morphogenesis

    Nie, Xuguang; Wang, Qin; Jiao, Kai

    2014-01-01

    MicroRNAs (miRNAs) play important roles in regulating gene expression during numerous biological/pathological processes. Dicer encodes an RNase III endonuclease that is essential for generating most, if not all, functional miRNAs. In this work, we applied a conditional gene inactivation approach to examine the function of Dicer during neural crest cell (NCC) development. Mice with NCC-specific inactivation of Dicer died perinatally. Cranial and cardiac NCC migration into target tissues was not affected by Dicer disruption, but their subsequent development was disturbed. NCC derivatives and their associated mesoderm-derived cells displayed massive apoptosis, leading to severe abnormalities during craniofacial morphogenesis and organogenesis. In addition, the 4th pharyngeal arch artery (PAA) remodeling was affected, resulting in interrupted aortic arch artery type B (IAA-B) in mutant animals. Taken together, our results show that Dicer activity in NCCs is essential for craniofacial development and pharyngeal arch artery morphogenesis. PMID:21256960

  7. Parent artery occlusion for ruptured "true" posterior communicating artery aneurysm.

    Mitsuhashi, Takashi; Takeda, Nobuaki; Oishi, Hidenori; Arai, Hajime

    2015-04-01

    A case of a patient with a ruptured true posterior communicating artery (PCoA) aneurysm is reported, who had been managed by early endovascular parent artery occlusion with coils. The small blister aneurysm was located at the proximal PCoA itself and directed superiorly. Postoperative course was uneventful. During 1-month follow-up, the patient recovered well and could care for herself. Aneurysms of the PCoA itself are very rare. As reported to date, surgical procedures would favor microsurgical clipping over endovascular coil embolization. Endovascular treatment may be a good alternative to surgical trapping for true PCoA blister aneurysm. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  10. Doppler changes of extracranial cerebral and peripheral arteries in cardiovascular diseases

    Dichev, P.

    1995-01-01

    In recent years Doppler sonography has been approved as a valuable noninvasive method for identification of the extracranial vascular obturations. On the other hand obturational pathology of the extracranial arteries have often been associated with different cardiovascular diseases, and this requires perfect awareness of blood flow changes in the latter. The current study considers the specific flow changes in extracranial cerebral arteries in patients with ischemic heart disease (III-IV) (functional grade - FG - NYHA), and those with concomitant congestive heart failure (III-IV FG), as compared to healthy subjects. In the patients with ischemic heart disease without heart failure the changes are not as significant as compared to healthy subjects (p<0.1). Congestive heart failure is related to significant changes in some of the Doppler parameters. In the last stage of congestive heart failure spectral waveform of the internal carotid arteries also changes. Additionally the changes of spectral waveform of the carotid arteries in different heart diseases are represented: Idiopathic Subvalvular Aortic Stenosis, Valvular Aortic Stenosis and Regurgitation, Supravalvular Aortic Stenosis, Aortic Coarctation, Patent Ductus Botalli, Orthostatismus, Tamponade. Some of the changes are very specific and the Doppler technique would be useful for diagnosis of these diseases. 7 refs., 12 figs. (author)

Se realizó con éxito la embolización endovascular con coils, sin complicaciones inmediatas. Los hallazgos de CT, RM y angiografía son presentados. Aunque cada una de estas variaciones son infrecuentes en forma individual, la combinación de las mismas no ha sido reportada en la literatura hasta nuestro conocimiento, siendo de enorme importancia en el manejo diagnóstico y terapéutico de pacientes con stroke de mecanismo embolico, así como para la planificación de procedimientos endovasculares diagnósticos y terapéuticos. We report the rare association of an aneurysm of a lateral right persistent trigeminal artery (Saltzman type II, bilateral aplasia of the pre-communicating segment of both posterior cerebral arteries and bilateral fetal posterior cerebral arteries, in a 64 years old woman who suffered from progressive diplopia and right abducens nerve palsy, most likely due to nerve compression in the latero-cellar space. Successful endovascular coils embolization of the aneurysm was performed, with no immediate complications. CT, MR and angiographic findings are presented. Although infrequent as single variations, the association of these three arterial variations has not been reported in literature to our knowledge, having special importance in the diagnostic workup and therapeutic procedures in a patient with an embolic stroke, as well as in the planification of intracranial endovascular diagnostic and therapeutic procedures.

  13. Arterial endothelial function measurement method and apparatus

    Maltz, Jonathan S; Budinger, Thomas F

    2014-03-04

    A "relaxoscope" (100) detects the degree of arterial endothelial function. Impairment of arterial endothelial function is an early event in atherosclerosis and correlates with the major risk factors for cardiovascular disease. An artery (115), such as the brachial artery (BA) is measured for diameter before and after several minutes of either vasoconstriction or vasorelaxation. The change in arterial diameter is a measure of flow-mediated vasomodification (FMVM). The relaxoscope induces an artificial pulse (128) at a superficial radial artery (115) via a linear actuator (120). An ultrasonic Doppler stethoscope (130) detects this pulse 10-20 cm proximal to the point of pulse induction (125). The delay between pulse application and detection provides the pulse transit time (PTT). By measuring PTT before (160) and after arterial diameter change (170), FMVM may be measured based on the changes in PTT caused by changes in vessel caliber, smooth muscle tone and wall thickness.

  14. Physiologic assessment of coronary artery fistula

    Gupta, N.C.; Beauvais, J. (Creighton Univ., Omaha, NE (USA))

    1991-01-01

    Coronary artery fistula is an uncommon clinical entity. The most common coronary artery fistula is from the right coronary artery to the right side of the heart, and it is less frequent to the pulmonary artery. The effect of a coronary artery fistula may be physiologically significant because of the steal phenomenon resulting in coronary ischemia. Based on published reports, it is recommended that patients with congenital coronary artery fistulas be considered candidates for elective surgical correction to prevent complications including development of congestive heart failure, angina, subacute bacterial endocarditis, myocardial infarction, and coronary aneurysm formation with rupture or embolization. A patient is presented in whom treadmill-exercise thallium imaging was effective in determining the degree of coronary steal from a coronary artery fistula, leading to successful corrective surgery.

    Autonomic sympathetic nerves innervate peripheral resistance arteries, thereby regulating vascular tone and controlling blood supply to organs. Despite the fundamental importance of blood flow control, how sympathetic arterial innervation develops remains largely unknown. Here, we identified the axon guidance cue netrin-1 as an essential factor required for development of arterial innervation in mice. Netrin-1 was produced by arterial smooth muscle cells (SMCs) at the onset of innervation, and arterial innervation required the interaction of netrin-1 with its receptor, deleted in colorectal cancer (DCC), on sympathetic growth cones. Function-blocking approaches, including cell type-specific deletion of the genes encoding Ntn1 in SMCs and Dcc in sympathetic neurons, led to severe and selective reduction of sympathetic innervation and to defective vasoconstriction in resistance arteries. These findings indicate that netrin-1 and DCC are critical for the control of arterial innervation and blood flow regulation in peripheral organs.

    Studies of transuranic organometallic complexes provide a particularly valuable insight into covalent contributions to the metal-ligand bonding, in which the subtle differences between the transuranium actinide ions and their lighter lanthanide counterparts are of fundamental importance for the effective remediation of nuclear waste. Unlike the organometallic chemistry of uranium, which has focused strongly on U(III) and has seen some spectacular advances, that of the transuranics is significantly technically more challenging and has remained dormant. In the case of neptunium, it is limited mainly to Np(IV). Here we report the synthesis of three new Np(III) organometallic compounds and the characterization of their molecular and electronic structures. These studies suggest that Np(III) complexes could act as single-molecule magnets, and that the lower oxidation state of Np(II) is chemically accessible. In comparison with lanthanide analogues, significant d- and f-electron contributions to key Np(III) orbitals are observed, which shows that fundamental neptunium organometallic chemistry can provide new insights into the behaviour of f-elements.

    2016-01-01

    Full Text Available Existe una estrecha relación entre el fortalecimiento del proceso de financiarización y la gestión de las diferentes monedas. Dicha relación aparece cuando en los espacios monetarios locales se abandona la demanda de moneda nacional en beneficio de alguna otra moneda o cualquier objeto especulativo. Se trata de una política económica a favor del beneficio financiero. En la gestión de las monedas locales, se impone la nueva norma de las altas finanzas: remuneración elevada, inflación escasa. El tipo de cambio en México está en función de las condiciones de confianza y rentabilidad del beneficio financiero. Las fluctuaciones en el tipo de cambio se convirtien en un factor determinante de las variaciones experimentadas por los flujos de tesorería, las ventas, los beneficios y los activos de las grandes empresas dedicadas a la actividad productiva cotizados en diversas monedas. Lo anterior se traduce en un atractivo para el capital monopolista ­financiero local, pues significa no sólo mantener su riqueza financiera y recibir íntegramente sus intereses, sino que también verse premiadas con un beneficio financiero, en su propia moneda. La certidumbre relativa sobre la evolución del tipo de cambio en la economía mexicana es una acción necesaria para que un sector importante de las grandes empresas relacionadas al capital – monopolista financiero mantenga sus condiciones de rentabilidad.

    The first supports for transmission power lines were relatively small structures, of simple configuration, to save reduced clearances to resist load in accordance with its need; with the technical development, gradually appeared higher and higher electric tensions and greater obstacles to overcome, consequently the design of the supports had to be adapted to the new conditions. This gave rise to the development of a specific technique that would adequate and incorporate the continuous engineering advances. In this document the initial considerations on the design poles pipe type are examined; within these considerations mention is made of: the design, the manufacture, the prototype tests, installation, quality control and foundations. The type tube pole is portrayed, as well as the steel reinforcement, finally the types of precast foundations are shown [Espanol] Los primeros soportes para lineas de transmision fueron estructuras relativamente pequenas, de configuracion simple, para salvar claros reducidos y resistir cargas proporcionales a sus necesidades, con el desarrollo de la tecnica, fueron apareciendo tensiones electricas cada vez mas elevadas y obstaculos mayores que vencer, por lo que el diseno de los soportes tuvo que adaptarse a las nuevas condiciones.

    Full Text Available Este artículo presenta una aplicación eficiente de un control por modelo de referencia sobre un robot de tipo SCARA. El control estudiado es un control predictivo funcional, el que hace uso de un modelo dinámico simplificado del robot. Los ensayos simulados se realizan sobre un robot de cuatro grados de libertad, tipo SCARA. Con el fin de comparar diferentes estrategias de control, se diseña un controlador clásico tipo PID y dos controladores basados en el modelo de referencia. En este último caso el sistema se linealiza y se desacoplada por realimentación, lo que transforma el sistema a controlar en un simple par de integradores. Al sistema lineal y desacoplado resultante se le aplica el control por par calculado y el control predictivo funcional. Los tres controladores estudiados se simulan sobre el robot SCARA con valores numéricos reales. Las pruebas permiten valorar las respuestas de estos controladores en seguimiento de trayectoria, rechazo de perturbaciones y presencia de errores en el modelado con consignas complejas similares a las utilizadas en procesos de fabricación.This paper describes an efficient approach for model based control, applied on a SCARA robot. The studied control is the predictive functional control which uses a simplified dynamical model of the robot. The simulated tests are made on a SCARA type robot, with four DOF. To compare several control strategies, a classical PID control and two model based controllers are designed. In the last case, the model is first linearized and decoupled by feedback, transforming the system into a double set of integrators. Computed torque control and predictive functional control are applied to the linear and decoupled system. The three studied controllers are simulated on the SCARA robot with real numerical values. Tracking performance, disturbance rejection and model robot mismatch are enlightened, using complex machining tasks trajectories and error presence in the modelling

    Over a seventeen-month period, a percutaneous transluminal removal of stenosing plaque material from leg and pelvic arteries was performed successfully and without complication in 43 patients. A complete atherectomy in the femoropopliteal vessels succeeded in 99% of cases. In the pelvic region, the primary results were much lower (58%). After six months, the angiographically checked restenosis rate was 17% for femoropopliteal vessels and 11% for iliac arteries, and the corresponding Kaplan-Meier cumulative patency rates were 73.8 and 78.7% respectively. Simpson's atherectomy is the only method of its kind that is therapeutically effective and diagnostically significant, since the removed plaque can be used for further tests. (orig.) [de

  6. [Arterial hypertension due to altitude].

    2008-01-01

    The behavior of blood pressure under hypoxic conditions depends on individual factors, altitude and duration of stay at altitude. While most humans are normotensive at higher altitudes, a few will react with moderate hypertension or hypotension. Excessive elevation of arterial blood pressure is not even to be expected below 4,000 m. Rather, several weeks' stay at higher altitude will decrease systolic and diastolic blood pressure at rest as well as during physical exertion. A high-altitude treatment for rehabilitation purposes at moderate altitude may be recommended for patients with cardio-circulatory disorders. Improvements can last several months even after returning to accustomed altitudes. Furthermore, endurance-trained hypertensive patients with pharmacologically controlled arterial blood pressure might be able to participate in mountain treks without additional health risk.

  7. Nanomedicine in coronary artery disease.

    Ambesh, Paurush; Campia, Umberto; Obiagwu, Chukwudi; Bansal, Rashika; Shetty, Vijay; Hollander, Gerald; Shani, Jacob

    Nanomedicine is one of the most promising therapeutic modalities researchers are working on. It involves development of drugs and devices that work at the nanoscale (10-9m). Coronary artery disease (CAD) is responsible for more than a third of all deaths in age group >35 years. With such a huge burden of mortality, CAD is one of the diseases where nanomedicine is being employed for preventive and therapeutic interventions. Nanomedicine can effectively deliver focused drug payload at sites of local plaque formation. Non-invasive strategies include thwarting angiogenesis, intra-arterial thrombosis and local inflammation. Invasive strategies following percutaneous coronary intervention (PCI) include anti-restenosis and healing enhancement. However, before practical application becomes widespread, many challenges need to be dealt with. These include manufacturing at the nanoscale, direct nanomaterial cellular toxicity and visualization.

    There is a growing interest to perform a left internal mammary artery (LIMA) graft to the left anterior descending coronary artery (LAD) on a beating heart through a minimally invasive access to the chest cavity. To report the experience with minimally invasive coronary artery surgery. Analysis of 11 patients aged 48 to 79 years old with single vessel disease that, between 1996 and 1997, had a LIMA graft to the LAD performed through a minimally invasive left anterior mediastinotomy, without cardiopulmonary bypass. A 6 to 10 cm left parasternal incision was done. The LIMA to the LAD anastomosis was done after pharmacological heart rate and blood pressure control and a period of ischemic pre conditioning. Graft patency was confirmed intraoperatively by standard Doppler techniques. Patients were followed for a mean of 11.6 months (7-15 months). All patients were extubated in the operating room and transferred out of the intensive care unit on the next morning. Seven patients were discharged on the third postoperative day. Duplex scanning confirmed graft patency in all patients before discharge; in two patients, it was confirmed additionally by arteriography. There was no hospital mortality, no perioperative myocardial infarction and no bleeding problems. After follow up, ten patients were free of angina, in functional class I and pleased with the surgical and cosmetic results. One patient developed atypical angina on the seventh postoperative month and a selective arteriography confirmed stenosis of the anastomosis. A successful angioplasty of the original LAD lesion was carried out. A minimally invasive left anterior mediastinotomy is a good surgical access to perform a successful LIMA to LAD graft without cardiopulmonary bypass, allowing a shorter hospital stay and earlier postoperative recovery. However, a larger experience and a longer follow up is required to define its role in the treatment of coronary artery disease.

Surgical treatment is the therapy of choice if ever possible; aggressive chemotherapy might be an acceptable alternative. (orig.) [de

  9. Impaired activity of adherens junctions contributes to endothelial dilator dysfunction in ageing rat arteries.

    Chang, Fumin; Flavahan, Sheila; Flavahan, Nicholas A

    2017-08-01

    compared to young arteries. Disruption of VE-cadherin clustering at AJs (function-blocking antibody, FBA) inhibited dilatation to acetylcholine in young, but not old, arteries. After the FBA, there was no longer any difference in dilatation between old and young arteries. Src activity and tyrosine phosphorylation of VE-cadherin were increased in old compared to young arteries. In old arteries, Src inhibition (saracatinib) increased: (i) 140 kDa VE-cadherin in the TTX-insoluble fraction, (ii) VE-cadherin intensity at AJs, (iii) AJ width, and (iv) acetylcholine dilatation. In old arteries treated with the FBA, saracatinib no longer increased acetylcholine dilatation. Saracatinib did not affect dilatation in young arteries. Therefore, ageing impairs AJ activity, which appears to reflect Src-induced phosphorylation, internalization and degradation of VE-cadherin. Moreover, impaired AJ activity can account for the endothelial dilator dysfunction in old arteries. Restoring endothelial AJ activity may be a novel therapeutic approach to vascular ageing. © 2017 The Authors. The Journal of Physiology © 2017 The Physiological Society.

  10. Synthesis and characterization of La(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), Tb(III) and Dy(III) complexes of 2-acetylfuran-2-thenoylhydrazone

    Singh, B.; Singh, Praveen K.

    1998-01-01

    The reaction of 2-acetylfuran-2-thenoylhydrazone(afth) with Ln(III) trichlorides yields complexes of the type [Ln(afth)Cl 2 (H 2 O)(EtOH)]Cl, [Ln(III) = La, Pr, Nd, Sm, Eu, Gd, Tb and Dy]. The complexes have been characterized by molar conductance, magnetic susceptibility and TGA and DTA measurements, magnetic susceptibility and TGA and DTA measurements, FAB mass, infrared, proton NMR, electronic absorption and emission spectra. The terbium complex is found to be monomer from the FAB mass spectrum. The IR and NMR spectra suggest neutral tridentate behaviour of the Schiff base. A coordination number seven is proposed around the metal ions. Emission spectra suggest C 3v , symmetry around the metal ion with capped octahedron geometry for the europium complex. (author)

    Thirteen bronchial arterial perfusion studies were performed in a total of 13 patients with lung tumors (11 cases of lung cancer, one metastatic tumor and one abscess), utilizing 99m TcO 4 - or 99m Tc-labeled macroaggregated albumin ( 99m Tc-MAA). Regions of interest (ROI) of the same size were set over areas of tumor, the mediastinum and healthy lung areas, and each ROI count was calculated by a nuclear medicine computer during an acquisition time period of 20 min with each tracer for 7 min to evaluate tumor part perfusion. The count ratios of tumor to healthy parts ranged from 1.7 to 6.5 (mean±s.d.; 3.8±1.9) in the 99m TcO 4 - group (10 patients) and from 130 to 230 (mean±s.d.; 163±30) in the 99m Tc-MAA group (3 patients), respectively. Tumor reduction rates 2 weeks after CDDP bronchial artery infusion therapy correlated positively to the count ratio in the 99m TcO 4 - lung cancer group, although significant correlation was not obtained. This study suggests that bronchial arterial infusion of anticancer agents may result in higher concentrations of anticancer agents in the tumors than with systemic chemotherapy and chemoembolic materials may exert more potent anticancer effects on tumors than nonparticulated anticancer agents.

    1990-01-01

    Fourteen cases of arterial occlusion or severe narrowing following radiotherapy are studied in order to assess the possible etiological role of such therapy in arterial lesion. Surgical results are also discussed in terms of long-term efficacy. The average time of occurrence after radiotherapy was 8 years post-radiotherapy. This series includes 7 supra-aortic trunk stenoses and 7 abdominal aorta trunk stenoses. The doses received in the volumes iradiated ranged from 47 to 70 Gy with standard fractionation. Association of atherosclerotic risk factors was present in 12 patients, but stenoses were usually confined to irradiated areas, and at imes occurred in uncommon sites. Surgical management included 11 by-passes, 2 endarterectomies and one percutaneous transluminal angioplasty. All patients experienced immediate and satisfactory functional improvements. Three patients were re-operated on because of the re-occlusion of the by-pass and graft infection. On the whole, stenoses in previously irradiated areas showed no particular difficulties for surgical treatment. It was concluded that radiotherapy seems to be a definite risk factor for arterial occlusion or narrowing, especially in association in association with atherosclerotic risk factors.

    Full Text Available The final most common pathway for the majority of coronary artery disease is occlusion of a coronary vessel. Under normal conditions, antithrombin III (AT III, protein C, and protein S as an active protein C cofactor, are natural anticoagulants (hemostatic control that balances procoagulant activity (thrombin antithrombin complex balance to prevent thrombosis. If the condition becomes unbalanced, natural anticoagulants and the procoagulants can lead to thrombosis. Thirty subjects with acute coronary syndrome (ACS were studied for the incidence of antithrombin III (AT III, protein C, and protein S deficiencies, and the result were compare to the control group. Among patients with ACS, the frequency of distribution of AT-III with activity < 75% were 23,3% (7 of 30, and only 6,7% ( 2 of 30 in control subject. No one of the 30 control subject have protein C activity deficient, in ACS with activity < 70% were 13,3% (4 of 30. Fifteen out of the 30 (50% control subjects had protein S activity deficiency, while protein S deficiency activity < 70% was found 73.3.% (22 out of 30. On linear regression, the deterministic coefficient of AT-III activity deficiency to the development ACS was 13,25 %, and the deterministic coefficient of protein C activity deficient to the development of ACS was 9,06 %. The cut-off point for AT-III without protein S deficiency expected to contribute to the development of vessel disease was 45%. On discriminant analysis, protein C activity deficiency posed a risk for ACS of 4,5 greater than non deficient subjects, and AT-III activity deficiency posed a risk for ACS of 3,5 times greater than non deficient subjects. On binary logistic regression, protein S activity acted only as a reinforcing factor of AT-III activity deficiency in the development of ACS. Protein C and AT III deficiency can trigger ACS, with determinant coefficients of 9,06% and 13,25% respectively. Low levels of protein C posed a greater risk of

    The purpose of this investigation was to evaluate surgical catheter implantation in the facial artery of horses and the long-term maintenance of such arteries using heparin and ascorbic acid as filling solution. Nine horses were implanted with a polyurethane catheter. The catheters were flushed with a heparin/ascorbic acid solution every 8h and remained patent for 25 days. Arterial blood samples were collected twice a day, and one exercise test that included serial blood samples and arterial pressure recordings was performed on a treadmill. Polyurethane catheters surgically implanted in the facial artery can be kept patent by filling with a heparin/ascorbic acid solution and provide convenient invasive arterial access in horses which is suitable for use for serial blood sampling and blood pressure recordings, even during exercise on treadmill.

    2018-01-01

    To identify the vertebral artery blood flow in different head positions in patients with positional vertigo with no specific diagnosis. Patients with history of vestibular symptoms associated with changes in head position were enrolled into the study. Healthy volunteers were evaluated as control group. Doppler ultrasonography examination of the cervical segment of the vertebral arteries was performed under three different head positions: (i) supine position, (ii) head hyperextended and rotated to the right side and (iii) head hyperextended and rotated to the left side. In the study group, right and left vertebral artery blood flow was significantly lower in the ipsilateral hyperextended position compared to standard supine position (respectively p = .014; p = .001), but did not differ significantly when compared between the standard supine and contralateral hyperextended positions (respectively = .959; p = .669). In the control group, left and right vertebral artery blood flow did not differ significantly when the head was hyperextended to the right or left sides compared to standard supine position (p > .05). Our data demonstrated that the etiology of vestibular complaints in patients with undiagnosed positional vertigo might be related to impairment in vertebral artery blood flow according to head positions.

    Full Text Available O presente artigo tem como objetivo uma revisita a referenciais bibliográficos a partir dos quais foi possível refletir sobre a construção de estereótipos relacionados à imagem feminina no século XX partindo-se do conceito de representação proposto por Moscovici (2003. Pretende-se na convergência destas duas categorias (representação e imagem apresentar olhares sobre a construção de alguns estereótipos relacionados às mulheres, uma vez que diversas instituições inclusive o próprio movimento feminista em suas variadas vertentes também preocuparam-se em “criar” representações das mulheres. Algumas discussões presentes neste artigo fizeram parte do conteúdo da disciplina “Seminários avançados sobre produtos, processos e discursos midiáticos” ofertada pelo Núcleo de Pós-Graduação da Universidade Federal de Sergipe. Desta forma pode-se refletir sobre os variados recortes imagéticos dos quais as instituições e as próprias mulheres utilizaram-se para compor novas representações.

  5. Avaliação química de fertilizantes com micronutrientes tipo fritas

    2003-02-01

    Full Text Available O objetivo deste trabalho foi analisar fertilizantes tipo fritas comercializados no Brasil, utilizando o método prescrito para análise de fertilizantes minerais não-fritas, o que normalmente tem sido feito na rotina pelos laboratórios de análises de fertilizantes. Também foram analisados os teores de Cd, Ni e Pb nesses fertilizantes. Observou-se que o método utilizado foi adequado para a análise dos fertilizantes tipo fritas, o que indica que as fritas comercializadas no Brasil não são realmente fritas, isto é, silicatos fundidos com micronutrientes. A presença de micronutrientes metálicos nos produtos sem as respectivas garantias e a alta concentração de metais indesejáveis, principalmente Pb, são fortes indícios de utilização de resíduos industriais na fabricação desses fertilizantes. Sugere-se que sejam estudados e propostos extratores químicos para avaliar a eficiência agrícola desses produtos.

  6. Tipos de fraudes en carnes y productos cárnicos: una revisión

    T. Espinoza

    2015-01-01

    Full Text Available En años recientes la importancia del control de alimentos, en cuanto a la identificación de sus componentes para evitar fraudes, ha crecido tanto en interés en las organizaciones estatales como en las empresas y en las industrias. La globalización, el aumento de las importaciones y exportaciones, y los tratados de libre comercio han propiciado un mayor intercambio y acceso de los alimentos a nivel mundial; junto con ello los problemas asociados a los fraudes tales como la adulteración, sustitución, la intencionalidad, y falsificación se han incrementado. Por ello, se han reportado varios trabajos asociados al fraude alimentario, donde en la mayoría de ellas se muestran aplicaciones de nuevas técnicas de identificación. Sin embargo, una discusión acerca de los tipos de fraude y su impacto sobre la sociedad, el bioterrorismo y la religión, ha sido poco abordada. Esta revisión se enfoca básicamente en describir los tipos de fraude en alimentos más comunes. Así como, se mencionan las recientes técnicas disponibles para detectar una adulteración en carnes.

    2006-01-01

    Full Text Available Beterrabas minimamente processadas apresentam vida de prateira curta, mesmo sob refrigeração, devido à descoloração superficial que deprecia a qualidade do produto. O objetivo do trabalho foi verificar o efeito de três tipos de corte em beterraba minimamente avaliando sua qualidade durante a conservação refrigerada. Os cortes utilizados foram: fatia, cubo e retalho. Após o processamento as beterrabas foram armazenadas a 5degreesC e as avaliações sendo realizadas durante dez dias a cada dois dias. Beterrabas em fatias apresentaram maior respiração e maiores perdas dos pigmentos betalaínas e de sólidos solúveis durante o armazenamento. Através de análise sensorial, verificou-se que a qualidade visual do produto foi mantida por até quatro dias, independente do tipo de corte. O fator que mais depreciou a qualidade de beterraba minimamente processada foi a perda de coloração das raízes (esbranquiçamento. Pode-se concluir que a beterraba minimamente processada em fatias ou cubo apresenta conservação de, no máximo 4 dias, a 5degreesC, enquanto minimamente processada em retalho apresenta 6 dias de conservação.

  12. Intracranial cerebral artery stenosis with associated coronary artery and extracranial carotid artery stenosis in Turkish patients

    Alkan, Ozlem [Department of Radiology, Baskent University, Faculty of Medicine, Ankara (Turkey)], E-mail: yalinozlem@hotmail.com; Kizilkilic, Osman; Yildirim, Tulin [Department of Radiology, Baskent University, Faculty of Medicine, Ankara (Turkey); Atalay, Hakan [Department of Cardiovascular Surgery, Baskent University, Faculty of Medicine, Ankara (Turkey)

    2009-09-15

    Purpose: Although it has been demonstrated that there is a high prevalence of extracranial carotid artery stenosis (ECAS) in patients with severe coronary artery disease, intracranial cerebral artery stenosis (ICAS) is rarely mentioned. We evaluated the prevalence of ICAS in patients with ECAS having elective coronary artery bypass grafting (CABG) surgery to determine the relations between ICAS, ECAS and atherosclerotic risk factors. Methods: We retrospectively reviewed the digital subtraction angiography findings of 183 patients with ECAS {>=} 50% preparing for CABG surgery. The analyses focused on the intracranial or extracranial location and degree of the stenosis. The degree of extracranial stenoses were categorized as normal, <50%, 50-69%, 70-89%, and 90-99% stenosis and occluded. The degree of intracranial stenosis was classified as normal or {<=}25%, 25-49%, and {>=}50% stenosis and occluded. Traditional atherosclerotic risk factors were recorded. Results: ECAS < 70% in 42 patients and ECAS {>=} 70% in 141 patients. ICAS was found in 51 patients and ICAS {>=} 50% in 30 patients. Regarding risk factors, we found hypertension in 135 patients, diabetes mellitus in 91 patients, hyperlipidemia in 84 patients, and smoking in 81 patients. No risk factor was significant predictors of intracranial atherosclerosis. The severity of ICAS was not significantly associated with that of the ECAS. Conclusions: We found ICAS in 27.8% of the patients with ECAS > 50% on digital subtraction angiography preparing for CABG. Therefore a complete evaluation of the neck vessels with magnetic resonance or catheter angiography seems to be indicated as well as intracranial circulation for the risk assessment of CABG.

    To assess the influence of calcified plaque characteristics on the overestimation of coronary arterial stenosis on a coronary CT angiography (CCTA). The study included 271 coronary arteries with calcified plaques identified by CCTA, and based on 928 coronary arteries from 232 patients who underwent both CCTA and invasive coronary angiography (ICA). Individual coronary arteries were classified into two groups by agreement based on the degree of stenosis from each CCTA and ICA: 1) group A includes patients with concordant CCTA and ICA results and, 2) group B includes patients with an overestimation of CCTA compared to ICA. Parameters including total calcium score, calcium score of an individual coronary artery, calcium burden number of an individual coronary artery, and the density of each calcified plaque (calcium score / number of calcium burden) for each individual coronary artery were compared between the two groups. Of the 271 coronary arteries, 164 (60.5%) were overestimated on CCTA. The left anterior descending artery (LAD) had a significantly low rate of overestimation (47.1%) compared to the other coronary arteries (p=0.001). No significant differences for total calcium score, calcium score of individual coronary artery, and the density of each calcified plaque from individual coronary arteries between two groups was observed. However, a decreasing tendency for the rate of overestimation on CCTA was observed with an increase in calcium burden of individual coronary arteries (p<0.05). The evaluation of coronary arteries suggests that the degree of coronary arterial stenosis had a tendency to be overestimated by calcified plaques on CCTA. However, the rate of overestimation for the degree of coronary arterial stenosis by calcified plaques was not significantly influenced by total calcium score, calcium score of individual coronary artery, and density of each calcified plaque

    The Shielded Neutron Assay Probe (SNAP) technique was developed to determine the leakage neutron source strength of a radioactive object. The original system consisted of an EberlineTM Mini-scaler and discrete neutron detector. The system was operated by obtaining the count rate with the EberlineTM instrument, determining the absolute efficiency from a graph, and calculating the neutron source strength by hand. In 2003 the SNAP III, shown in Figure 1, was designed and built. It required the operator to position the SNAP, and then measure the source-to-detector and detectorto- reflector distances. Next the operator entered the distance measurements and started the data acquisition. The SNAP acquired the required count rate and then calculated and displayed the leakage neutron source strength (NSS). The original design of the SNAP III is described in SNAP III Training Manual (ER-TRN-PLN-0258, Rev. 0, January 2004, prepared by William Baird) This report describes some changes that have been made to the SNAP III. One important change is the addition of a LEMO connector to provide neutron detection output pulses for input to the MC-15. This feature is useful in active interrogation with a neutron generator because the MC-15 has the capability to only record data when it is not gated off by a pulse from the neutron generator. This avoids recording of a lot of data during the generator pulses that are not useful. Another change was the replacement of the infrared RS-232 serial communication output by a similar output via a 4-pin LEMO connector. The current document includes a more complete explanation of how to estimate the amount of moderation around a neutron-emitting source.

  4. Basel III and Asset Securitization

    M. Mpundu

    2013-01-01

    Full Text Available Asset securitization via special purpose entities involves the process of transforming assets into securities that are issued to investors. These investors hold the rights to payments supported by the cash flows from an asset pool held by the said entity. In this paper, we discuss the mechanism by which low- and high-quality entities securitize low- and high-quality assets, respectively, into collateralized debt obligations. During the 2007–2009 financial crisis, asset securitization was seriously inhibited. In response to this, for instance, new Basel III capital and liquidity regulations were introduced. Here, we find that we can explicitly determine the transaction costs related to low-quality asset securitization. Also, in the case of dynamic and static multipliers, the effects of unexpected negative shocks such as rating downgrades on asset price and input, debt obligation price and output, and profit will be quantified. In this case, we note that Basel III has been designed to provide countercyclical capital buffers to negate procyclicality. Moreover, we will develop an illustrative example of low-quality asset securitization for subprime mortgages. Furthermore, numerical examples to illustrate the key results will be provided. In addition, connections between Basel III and asset securitization will be highlighted.

    Studies of transuranic organometallic complexes provide a particularly valuable insight into covalent contributions to the metal-ligand bonding, in which the subtle differences between the transuranium actinide ions and their lighter lanthanide counterparts are of fundamental importance for the effective remediation of nuclear waste. Unlike the organometallic chemistry of uranium, which has focused strongly on UIII and has seen some spectacular advances, that of the transuranics is significantly technically more challenging and has remained dormant. In the case of neptunium, it is limited mainly to NpIV. Here we report the synthesis of three new NpIII organometallic compounds and the characterization of their molecular and electronic structures. These studies suggest that NpIII complexes could act as single-molecule magnets, and that the lower oxidation state of NpII is chemically accessible. In comparison with lanthanide analogues, significant d- and f-electron contributions to key NpIII orbitals are observed, which shows that fundamental neptunium organometallic chemistry can provide new insights into the behaviour of f-elements.

    A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

  8. [Secondary Arterial Hypertension: Uncertainties in Diagnosis].

    Dinis, Paulo Gomes; Cachulo, Maria Carmo; Fernandes, Andreia; Paiva, Luis; Gonçalves, Lino

    2017-06-30

    Arterial hypertension is regarded today as a global public health problem, and the prevalence rate in Portugal is 26.9%. According to the etiology, is classified into primary or secondary arterial hypertension. In about 90% of cases it is not possible to establish a cause, so is called primary arterial hypertension. In the remaining 5 to 10%, it can be identified secondary causes, which are potentially treatable. For secondary arterial hypertension study to be cost-effective, it is essential to understand which patients investigate, and evaluate the best strategy to adopt. The main causes identified as responsible for secondary arterial hypertension are: kidney disease; endocrine and vascular diseases and obstructive sleep apnea. Among these some are consensual, and others more controversial in the literature. In this regard we present two cases of arterial hypertension, which are potentially secondary in etiology, but still focus of debate.

    Renal Artery Stenosis (RAS), is one of the causes of secondary hypertension; there are many causes of renal artery stenosis, as atherosclerosis of the renal artery which account for 90% of cases of RAS; fibromuscular dysplasia accounts for 10% of RAS. Various causes of thrombophilia either due congenital causes or acquired causes and can lead to RAS. Our patient was presented by acute attack of epistaxis and hypertension. Angiography of the Renal Arteries,are showed no sign of renal artery stenosis. However, the right kidney showed upper pole infarction, and the left kidney showed evidence of functional lower pole renal artery stenosis, although there is no anatomical stenosis detected in angiography. Work up for the cause of thrombophilia did not help in the diagnosis, which may be due to an undiscovered cause of thrombophilia

    We describe a successful percutaneous transluminal dilatation (PTD) of an innominate artery stenosis in a 40-year-old patient with aortic arch syndrome. Five years earlier both a left central carotid artery occlusion and an innominate and left subclavian artery stenosis were treated by grafting from the aorta to the distal vessels. At recurrence of the neurological symptoms, reocclusion of the graft to the innominate artery and subtotal stenosis of the left carotid anastomosis were noted. The prevent the hazards of a reoperation, the innominate artery stenosis was dilated by means of PTD via the right brachial artery. Success of the procedure was demonstrated by Doppler sonography and angiography. It appears that PTD serves as an excellent method of treating stenoses of the aortic arch branches in aortic arch syndrome. (orig.)

    Full Text Available A pinheira (Annona squamosa L. ocorre espontaneamente no Nordeste Brasileiro, onde é explorada de forma extrativista, caracterizando-se pela falta de manejo adequado e material genético selecionado. Nesse sentido, foi realizado um experimento com objetivo de avaliar a produtividade, as características físicas e químicas de frutos de dez genótipos de pinheira no município de Bom Jesus, PI. Adotou-se delineamento inteiramente casualizado, com tratamentos representados por dez genótipos de pinheira e três repetições. Foram avaliadas as seguintes variáveis: vitamina C, acidez titulável, sólidos solúveis, relação SS/AT "ratio", diâmetros longitudinal e transversal, relação DL/DT, número se sementes por fruto, massa dos frutos e produção por planta. Os genótipos apresentam diferenças quanto às características químicas, físicas e produtivas dos frutos. Os genótipos foram agrupados em sete grupos, com destaque para o grupo III (Gen-02 e grupo IV (Gen-05, fato que explicitou as diferenças entre os genótipos de pinheira quanto às características produtivas e químicas e físicas dos frutos. Genótipos Gen-01 e Gen-02 apresentam potencial para instalação em plantios comerciais, pela produtividade, formato do fruto ou por caracterizarem fontes naturais de vitamina C.The sugar apple (Annona squamosa L. is native to tropical America, occurring spontaneously in Northeastern Brazil, where it is exploited mainly as subsistence without adequate management and without genetic material selection. An experiment was developed aiming to evaluate yield, physical and chemical characteristics of the fruits of ten sugar apple genotypes in Bom Jesus, Piauí State, Brazil. A completely randomized design with treatments represented by ten genotypes and three replications was adopted. The following variables were evaluated: vitamin C, titratable acidity, soluble solids, SS/TA ratio, longitudinal diameter and transverse, LD/TD, number of

    Here, we report a case of a 30-year-old woman who presented with primary postpartum hemorrhage due to uterine atony. She received uterine artery embolization (UAE). During left internal iliac arteriography, an aberrant left ovarian artery originating from the left iliolumbar artery was visualized. The aberrant left ovarian artery was connected to the left uterine artery via prominent collateral vessels. It supplied a significant amount of blood to the fundus of the uterus. Bilateral hypertrophied uterine arteries were embolized very carefully so that the embolic material did not reflux into the aberrant left ovarian artery. After the procedure, her vaginal bleeding was successfully controlled. Accurate understanding of anatomical variations of the ovarian artery is essential to avoid failure in controlling postpartum hemorrhage with UAE.

    Conclusions: Using multiple arterial grafts did not add a significant risk or time to the classic CABG. With accumulating evidence about better patency rate in arterial grafts, MAR is recommended especially in younger patients undergoing CABG.

  16. Arterial scan versus radiographic angiography in detection of shallow arterial ulcers

    A comparison of 99m-technetium albumin aggregated arterial scan and radiographic angiography for detection of shallow intimal carotid artery ulcerations was made in a series of 12 anesthetized dogs, having a total of 16 acute arterial ulcerations. Radiographic angiography showed positive findings related to presence of stenosis or mural thrombosis in 12 instances. Direct visualization of ulceration was only exceptionally encountered. Arterial scan detected 14 of 16 intimal ulcers. The radionuclide method was reliable even in absence of stenosis or when only minimal mural thrombosis was present. Moreover, autopsy scan of the isolated arterial segments detected all 16 intimal lesions. These results indicate that the arterial scan was a more reliable method for detection of shallow arterial ulcers in this experimental model than radiographic angiography, especially when arterial lumen stenosis or mural thrombosis was minimal or absent

    Objective: To study the feasibility of establishing experimental model of human internal carotid artery siphon segment in canine common carotid artery (CCA) by end-to-end anastomoses of one side common carotid artery segment with the other side common carotid artery. Methods: Surgical techniques were used to make siphon model in 8 canines. One side CCA was taken as the parent artery and anastomosing with the cut off contra-lateral CCA segment which has passed through within the S-shaped glass tube. Two weeks after the creation of models angiography showed the model siphons were patent. Results: Experimental models of human internal carotid artery siphon segment were successfully made in all 8 dogs. Conclusions: It is practically feasible to establish experimental canine common carotid artery models of siphon segment simulating human internal carotid artery. (authors)

  18. Percutaneous transluminal angioplasty of the carotid artery

    The successful dilatation of postsurgical concentric stenosis of an internal carotid artery using percutaneous transluminal angioplasty (PTA) is reported here. Only one such case has been previously documented. Review of the literature disclosed 16 patients who received transluminal angioplasty for stenosis of carotid arteries by percutaneous or open arteriotomy techniques. The authors feel that PTA may be the treatment of choice for postoperative concentric stenosis of a short segment of the carotid artery as opposed to surgical repair. (orig.)

    Hypertension is associated to co-morbidities such as diabetes mellitus, coronary artery disease, stroke, peripheral vascular disease, chronic renal failure, entities that decrease life span. Peruvians suffer from arterial hypertension with characteristics similar to those of the general population. Early detection and treatment of hypertension should benefit them with years of quality of life. The occurrence of arterial hypertension in women from childhood through menopause, including reprodu...

    Subarachnoid hemorrhage (SAH) is a serious condition, occurring more frequently in females than in males. SAH is mainly caused by rupture of an intracranial aneurysm, which is formed by localized dilation of the intracranial arterial vessel wall, usually at the apex of the arterial bifurcation. T....... The female preponderance is usually explained by systemic factors (hormonal influences and intrinsic wall weakness); however, the uneven sex distribution of intracranial aneurysms suggests a possible physiologic factor-a local sex difference in the intracranial arteries....
