RESUMO

INTRODUCTION: The transradial approach for coronary artery catheterisation has increased in popularity compared to the transfemoral approach for patients undergoing percutaneous coronary interventions. However, radial artery spasm continues to be a major complication of the procedure. Current management strategies vary concerning radial artery spasm and there is limited evidence of practice in the Australian context. AIM: To identify the predictors of radial artery spasm and the medications used for its prevention and management. METHODS: A descriptive cross-sectional study was carried out over a three-month period in two tertiary hospitals in NSW, Australia. A self-administered pre-procedural survey was completed by patients undergoing coronary artery catheterisation. This survey collected socio-demographic data and assessed anxiety using the Spielberger State-Trait Anxiety Inventory. Procedural data, including length of procedure, equipment used, occurrence of radial artery spasm, and medications given, were collected post-procedure by the interventionalist. RESULTS: Of the 169 participants, over half were male (59.8%) and aged 66 years or older (56.8%). Radial artery spasm was reported in 24 (14.2%) participants. Rates of spasm were significantly higher among females (66.6%, p = 0.004), those aged under 65 years (62.5%, p = 0.001) and those who reported a medical history of anxiety (33.3%, p = 0.0004). There were no significant differences in State and Trait anxiety scores among those who had RAS and those who did not. Logistic regression identified younger age as the only statistically significant predictor of RAS (OR 0.536; 95% CI 0.171-1.684; p = 0.005). To prevent radial artery spasm most patients received midazolam (n = 158; 93.5%), nitrates (n = 133; 78.7%) and/or fentanyl (n = 124; 73.4%) prophylactically. Nitrates were the most frequently administered medication to treat radial artery spasm (78.7%). CONCLUSION: This study highlights that there is a need to develop a clearer understanding of the predictors of RAS, as identifying patients at risk can ensure prophylactic measures are implemented. This study identified nitrates as the preferred vasodilator as a preventative measure along with the use of sedation.

RESUMO

The human radial artery pulse carries a rich array of biomedical information. Accurate detection of pulse signal waveform and the identification of the corresponding pulse condition are helpful in understanding the health status of the human body. In the process of pulse detection, there are some problems, such as inaccurate location of radial artery key points, poor signal noise reduction effect and low accuracy of pulse recognition. In this system, the pulse signal waveform is collected by the main control circuit and the new piezoelectric sensor array combined with the wearable wristband, creating the hardware circuit. The key points of radial artery are located by an adaptive pulse finding algorithm. The pulse signal is denoised by wavelet transform, iterative sliding window and prediction reconstruction algorithm. The slippery pulse and the normal pulse are recognized by feature extraction and classification algorithm, so as to analyze the health status of the human body. The system has accurate pulse positioning, good noise reduction effect, and the accuracy of intelligent analysis is up to 98.4%, which can meet the needs of family health care.

RESUMO

OBJECTIVE: To analyze the Doppler ultrasound blood flow of Renying (carotid artery) pulse, Cunkou (radial artery) pulse, and Fuyang (anterior tibial artery) pulse in the normal group and the functional constipation with gastrointestinal heat (FCGH) group, and to compare and explore the differences of Renying, Cunkou and Fuyang pulses. METHODS: Sixty normal subjects and 60 patients with gastrointestinal heat constipation were collected in the department of ultrasound, Beijing Anzhen Hospital, Capital Medical University. Doppler ultrasound was used to observe the blood flow indexes including maximum systolic velocity (Vp), maximum diastolic velocity (Vd), mean velocity (Vm), pulse index (PI), resistance index (RI), vascular diameter (D), and circulation blood flow cycle (ET) of Renying pulse, Cunkou pulse and Fuyang pulse in the normal group and patients with gastrointestinal heat constipation. The differences of these three pulses were compared between the normal group and the FCGH group. RESULTS: The PI, Vp, Vm, RI, and D of the three pulses in the normal group were statistically significant different ( < 0.01). In the comparison of Doppler flow diagram of three pulses in the FCGH group, there were significant differences in PI, Vd, Vp, Vm, RI, and D ( < 0.01). CONCLUSION: Under normal conditions, the indexes of Renying pulse Doppler flow diagram, Cunkou pulse Doppler flow diagram, and Fuyang pulse Doppler flow diagram are significantly different. In the FCGH group, most of the indexes of Renying pulse Doppler flow diagram, Cunkou pulse Doppler flow diagram, and Fuyang pulse Doppler flow diagram are different. This result verified the necessity of simultaneous examinations of all Renying, Cunkou, and Fuyang pulses in modern Chinese medicine.

RESUMO

OBJECTIVES: To assess differences in radiation exposure between transradial access (TRA) and transfemoral access (TFA) for coronary procedures. BACKGROUND: TRA is associated with increased radiation exposure as compared to TFA. We compared radiation exposure between the two access sites. METHODS: Databases were searched from June 2014 to August 2021 for randomized controlled trials (RCTs) reporting coprimary outcomes of fluoroscopy time (FT) and/or dose area product (DAP) comparing TRA with TFA. Meta-regression was performed to assess the behavior of weighted mean difference (WMD) in FT from 1995 to 2021. Observational study data was used for corroborative evidence. RESULTS: Data from 8 RCTs (11,611 patients) showed the WMD of FT was 0.62 min (37 s) (95% confidence interval [CI]: [0.08-1.17], p = 0.023) in favor of TFA, WMD in DAP (9169 patients) was 1.94 Gy.cm2 (95% CI: [-2.1 to 5.9], p = 0.35) showing no significant difference. Pooled data from OBS and RCTs (83,990 patients) showed a similar trend. Studies from outside US between 1995 and 2021 showed WMD of FT between TRA and TFA of 0.88 min (52 s) (95% CI: [0.67-1.09], p = 0.005) versus 2.1 min (126 s) (95% CI: [1.38-2.8], p = 0.005) for US in favor of TFA. Meta-regression showed a declining WMD of FT between TRA and TFA from 1.6 min (96 s) in 1996 to 0.5 min (30 s) in 2020 with the lower limit of CI crossing the zero line in 2019. CONCLUSION: Radiation exposure between TRA and TFA continues to decrease overtime and is becoming clinically nonsignificant.

RESUMO

BACKGROUND AND PURPOSE: Transradial access (TRA) has increased popularity among neurointerventionalists during a short time period but until recently there have been no devices designed especially for radial use. MATERIALS AND METHODS: Consecutive neurointerventional procedures with an intention to perform TRA with the Rist radial access guide catheter between April 2021 and May 2022 were retrospectively reviewed. Possible access site complications, other procedure-related complications and information on successful catherization of the target vessel as well as whether the procedure had been successful were collected. RESULTS: Information from 100 patients was included in the study. The most general procedure was flow diversion (29%) followed by WEB embolization (20 %). Four patients (4%) needed conversion to femoral access. The triaxial system was used in 76% of the procedures. Four patients (4%) experienced access site or device related complications, none of those were serious. Six patients had clinically relevant procedure related complications. CONCLUSIONS: It is concluded that the Rist device can be used safely for a large variety of neurointerventions with a short learning curve.

RESUMO

The radial artery pulse wave contains a wealth of physiological and pathological information about the human body, and non-invasive studies of the radial artery pulse wave can assess arterial vascular elasticity in different age groups.The piezoelectric pulse wave transducers were used to non-invasively acquire radial artery pulse waves at different contact pressures in young and middle-aged and elderly populations. The radial artery waveforms were decomposed using a triangular blood flow model fitting method to obtain forward and reflected waves and calculate reflection parameters. Finally a correlation analysis and regression analysis of the contact pressure Psensor with the reflection parameters was carried out. The results showed that the reflection parameters RM, RI and Rd had a strong negative correlation with Psensor in both types of subjects, and the correlation coefficients and slopes of the regression curves were significantly different between the two types of subjects (P<0.05). Based on the results of this study, excessive contact pressure on the transducer should be avoided when detecting radial artery reflection waves in clinical practice. The results also show that the magnitude of the slope of the regression curve between the reflection parameters and the transducer contact pressure may be a potentially useful indicator for quantifying the elastic properties of the vessel.

RESUMO

The conventional radial approach has become the access route of choice for performing diagnostic or therapeutic coronary angiography. It has taken precedence over the femoral approach, which is subject to a higher rate of vascular and hemorrhagic complications. The distal radial approach is currently considered a further refinement of the conventional radial approach. It offers the advantage of potentially reducing local vascular complications (spasm, thrombosis of the radial artery), of allowing rapid mobilization of the wrist (hemostatic band against the scaphoid), of reducing the duration of hemostasis, and of preserving the proximal radial artery for future procedures such as arteriovenous bypasses or shunts. The use of the left distal radial access also makes it possible to avoid the restriction of the movements of the right hand after the catheterization, to improve the comfort of the operator during the procedure and to reduce exposure to radiations, as well as to offer the possibility of performing angiography in patients who have already undergone bypass surgery with the left internal mammary artery graft (LIMA).


L'approche radiale conventionnelle est devenue la voie d'accès de choix pour la réalisation d'une coronarographie diagnostique ou thérapeutique. Elle a pris le pas sur la voie fémorale sujette à un taux de complications vasculaires et hémorragiques plus important. L'approche radiale distale est actuellement considérée comme un raffinement supplémentaire de l'accès radial conventionnel. Elle offre l'avantage de potentiellement diminuer les complications vasculaires locales (spasme, thrombose de l'artère radiale), de permettre une mobilisation rapide du poignet (bande hémostatique contre le scaphoïde), de réduire la durée de l'hémostase, et de conserver l'artère radiale proximale pour des procédures futures telles que des pontages ou des shunts artério-veineux. L'utilisation de l'accès radial distal gauche permet, en plus, d'éviter la restriction des mouvements de la main droite après le cathétérisme (avantage appréciable chez les droitiers), d'améliorer le confort de l'opérateur pendant la procédure tout en réduisant son exposition aux radiations, et d'offrir la possibilité d'effectuer une angiographie chez les patients ayant déjà subi un pontage avec greffe de l'artère mammaire interne gaughe (AMIG).

RESUMO

INTRODUCTION: Coronary artery bypass grafting can be conducted using the radial artery as a bypass graft. However, it remains unclear which harvesting method is superior, i.e. endoscopic or open radial artery, and which site for proximal anastomosis of the radial artery has the greatest benefits? METHODS: The NEO Trial is a single site randomised clinical trial with a 2 × 2 factorial design. The first comparison assesses endoscopic versus open radial artery harvest with a primary outcome of hand function and secondary outcomes of neurological deficits through clinical exams and neurophysiological studies. The primary outcome is postoperatively hand function at three months. We anticipate a mean difference of 3 points with a standard deviation of 8 points, a power of 90%, and a type I error of 5%, resulting in a required sample size of 300 participants randomised 1:1. Secondary outcomes are neurological deficits (based on nerve conduction measurements, algometry test and von Frey hair test), clinical neurological examination of cutaneous sensibility, and registration of complications in the donor arm (haematoma formation, wound dehiscence, and/or infection). The second comparison assesses two different proximal anastomotic sites, i.e. aorto-radial anastomosis versus mammario-radial anastomosis. The primary outcome is a composite of cerebrovascular events and the secondary outcome is graft patency evaluation by multi-slice computer tomography-scan. These outcomes will be assessed at 1 year postoperatively, and the results of this comparison will be exploratory only. Both comparisons will be analysed using intention-to-treat and intervention groups will be compared using linear regression, logistic regression, or Mann-Whitney U test depending on data type. Two independent statisticians will follow the present plan and conduct the analyses which will hereafter be fused into a final analysis based on consensus. CONCLUSION: This detailed analysis plan will increase the validity of the NEO trial results by predefining the statistical analysis in detail.

RESUMO

BACKGROUND: Distal trans-radial access (dTRA) is a novel technique of arterial cannulation in coronary interventions. The comparative efficacy of dTRA and conventional trans-radial access (TRA) in attenuating peri-procedural complications is unknown. METHODS: Embase and PubMed/MEDLINE were searched from their inception until June 25, 2022, for randomized clinical trials. Outcomes included were radial artery occlusion (RAO), radial artery spasm, hemostasis time, access time, unsuccessful cannulation, crossover rate, and early discharge after trans-radial stenting of coronary arteries (EASY) type I-III hematomas. Statistical analysis was conducted using the random effects model to derive risk ratios (RRs) and mean differences (MDs) with their corresponding 95% confidence intervals (CIs). RESULTS: A total of 6 randomized clinical trials comprising 3240 patients were included. Subjects were predominantly male (73%) and had a mean age of 66 years. The dTRA group had a lower risk of RAO [RR 0.43 (95% CI, 0.26-0.69); P = 0.0005; I 2 = 0%] and had a shorter hemostasis time [MD -22.85 min (95% CI, -39.06 to -6.65); P = 0.006; I 2 = 99%]. The dTRA group had a higher crossover rate [RR 3.04 (95% CI, 1.88-4.91); P = 0.00001; I 2 = 56%] and a longer access time [MD 0.68 min (95% CI, 0.17-1.18); P = 0.009; I 2 = 99%]. The TRA group had a lower rate of unsuccessful cannulation [RR 0.81 (95% CI, 0.70-0.95); P = 0.01; I 2 = 92%]. There was no significant difference between the groups for radial artery spasm and EASY type I-III hematomas. CONCLUSION: dTRA is a safe alternative to conventional TRA for coronary interventions with a lower risk of RAO. Future trials are required to further compare both approaches.

RESUMO

BACKGROUND: Percutaneous coronary intervention (PCI) is a safe and effective therapy for patients with obstructive coronary artery disease (CAD). We aimed to assess the correlation between the success rate of angiography and the maximum insertion length and resistance of a soft-tipped guidewire. METHODS: Five hundred twenty-one patients were treated by successful radial artery puncture. According to whether the guidewire resistance, the patients were divided to three groups. 17 patients were maximum insertion length of guidewire ≤ 30 cm when resistance was encountered (group 1). 17 patients were maximum insertion length of guidewire between 30 and 45 cm when resistance was encountered (group 2). 487 patients were no resistance encountered (group 3). RESULTS: The coronary angiography success rates of group 1, 2, and 3 were 52.94%, 47.05%, 98.97%, respectively. Typically, angiography can be completed in patients with Ω-shaped, S-shape or Z-shaped tortuosity. CONCLUSIONS: The maximum insertion length of straight guidewire and resistance can be used to determine radial artery status. The radial artery tortuosity or spasm significantly affects the success rate of coronary angiography.

RESUMO

BACKGROUND: Emerging evidence from randomized clinical trials (RCTs) comparing distal radial access (DRA) with conventional radial access (RA) is available. OBJECTIVES: The aim of this study was to provide a quantitative appraisal of the effects of DRA) vs conventional RA for coronary angiography with or without intervention. METHODS: The PubMed, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched for RCT comparing DRA vs conventional RA for coronary angiography and/or intervention. Data were pooled by meta-analysis using a random-effects model. The primary endpoint was radial artery occlusion (RAO) at the longest available follow-up. RESULTS: Fourteen studies enrolling 6,208 participants were included. Compared with conventional RA, DRA was associated with a significant lower risk of RAO, either detected at latest follow-up (risk ratio [RR]: 0.36; 95% CI: 0.23-0.56; P < 0.001; number needed to treat [NNT] = 30) or in-hospital (RR: 0.32; 95% CI: 0.19-0.53; P < 0.001; NNT = 28), as well as EASY (Early Discharge After Transradial Stenting of Coronary Arteries) ≥II hematoma (RR: 0.51; 95% CI: 0.27-0.96; P = 0.04; NNT = 107). By contrast, DRA was associated with a higher risk of access site crossover (RR: 3.08; 95% CI: 1.88-5.06; P < 0.001; NNT = 12), a longer time for radial puncture (standardized mean difference [SMD]: 3.56; 95% CI: 0.96-6.16; P < 0.001), a longer time for sheath insertion (SMD: 0.37; 95% CI: 0.16-0.58; P < 0.001), and a higher number of puncture attempts (SMD: 0.59, 95% CI: 0.48-0.69; P < 0.001). CONCLUSIONS: Compared with conventional RA, DRA is associated with lower risks of RAO and EASY ≥II hematoma but requires longer time for radial artery cannulation and sheath insertion, more puncture attempts, and a higher access site crossover.

RESUMO

Pulse measurements made using wearable devices can aid the monitoring of human physiological condition. Accurate estimation of waveforms is often difficult for nonexperts; motion artifacts may occur during tonometry measurements when the skin-sensor contact pressure is insufficient. An alternative approach is to extract only high-quality pulses for use in index calculations. The present study aimed to determine the effectiveness of using machine-learning analysis in discriminating between high-quality and low-quality pulse waveforms induced by applying different contact pressures. Radial blood pressure waveform (BPW) signals were measured noninvasively in healthy young subjects using a strain-gauge transducer. One-minute-long trains of pulse data were measured when applying the appropriate contact pressure (67.80 ± 1.55 mmHg) and a higher contact pressure (151.80 ± 3.19 mmHg). Eight machine-learning algorithms were employed to evaluate the following 40 harmonic pulse indices: amplitude proportions and their coefficients of variation and phase angles and their standard deviations. Significant differences were noted in BPW indices between applying appropriate and higher skin-surface contact pressures. The present appropriate contact pressure could not only provide a suitable holding force for the wearable device but also helped to maintain the physiological stability of the underlying tissues. Machine-learning analysis provides an effective method for distinguishing between the high-quality and low-quality pulses with excellent discrimination performance (leave-one-subject-out test: random-forest AUC = 0.96). This approach will aid the development of an automatic screening method for waveform quality and thereby improve the noninvasive acquisition reliability. Other possible interfering factors in practical applications can also be systematically studied using a similar procedure.

RESUMO

This paper's novel focus is predicting the leaf nitrogen content of rice during growing and maturing. A multispectral image processing-based prediction model of the Radial Basis Function Neural Network (RBFNN) model was proposed. Moreover, this paper depicted three primary points as the following: First, collect images of rice leaves (RL) from a controlled condition experimental laboratory and new shoot leaves in different stages in the visible light spectrum, and apply digital image processing technology to extract the color characteristics of RL and the morphological characteristics of the new shoot leaves. Secondly, the RBFNN model, the General Regression Model (GRL), and the General Regression Method (GRM) model were constructed based on the extracted image feature parameters and the nitrogen content of rice leaves. Third, the RBFNN is optimized by and Partial Least-Squares Regression (RBFNN-PLSR) model. Finally, the validation results show that the nitrogen content prediction models at growing and mature stages that the mean absolute error (MAE), the Mean Absolute Percentage Error (MAPE), and the Root Mean Square Error (RMSE) of the RFBNN model during the rice-growing stage and the mature stage are 0.6418 (%), 0.5399 (%), 0.0652 (%), and 0.3540 (%), 0.1566 (%), 0.0214 (%) respectively, the predicted value of the model fits well with the actual value. Finally, the model may be used to give the best foundation for achieving exact fertilization control by continuously monitoring the nitrogen nutrition status of rice. In addition, at the growing stage, the RBFNN model shows better results compared to both GRL and GRM, in which MAE is reduced by 0.2233% and 0.2785%, respectively.

RESUMO

La enfermedad de Behçet es una vasculitis multisistémica cuya etiopatogenia es aún desconocida. Las complicaciones arteriales que tienen una relación directa con la enfermedad en las formas pediátricas son muy raras. Reportamos un caso inusual de la enfermedad de Behçet en un niño de 13 años que fue revelado por la ruptura de un falso aneurisma de la arteria radial. Fue tratado con urgencia por la ligadura arterial seguida de una combinación de corticosteroides y colchicina. A través de este trabajo intentamos averiguar las características de las lesiones arteriales en los niños con enfermedad de Behçet en comparación con la forma adulta.(AU)


Behçet’s disease is a multisystem vasculitis whose aetiopathogenesis is still unknown. Arterial complications directly related to the disease in paediatric forms are very rare. We report an unusual case of Behçet’s disease in a 13-year-old boy who was revealed by a ruptured false aneurysm of the radial artery. He was treated urgently by arterial ligation followed by a combination of corticosteroids and colchicine. Through this work we tried to find out the characteristics of the arterial lesions in children with Behçet’s disease compared to the adult form.

RESUMO

Complex and higher-risk indicated percutaneous coronary interventions at times require mechanical circulatory support, most often with Impella devices. The use of such devices traditionally required additional arterial access site(s), increasing risk of vascular complications. The Single-access for Hi-risk percutaneous coronary intervention (SHiP) technique was described to overcome this issue but was limited to the use of 7F guides. Larger 8F guides often provide incremental support and space compared to 7F guides, sometimes needed in complex procedures. We described a modified SHiP technique using an 8 Fr guide delivered sheathless using Rotaglide.
