    Artéria radial versus veia safena para revascularização do miocárdio: metanálise (não houve diferença estatisticamente significante)
    (Sociedade Brasileira de Cirurgia Cardiovascular, 2006-09-01) Locali, Rafael Fagionato [UNIFESP]; Buffolo, Enio [UNIFESP]; Catani, Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    OBJECTIVE: To compare the effectiveness of radial artery graft with saphenous vein graft to myocardial revascularization, in association with the internal thoracic artery. METHODS: We made a systematic review of literature, using a strategy to search articles applied to MEDLINE and LILACS databases. Two independent researchers have carried through the election of identified articles, evaluating carefully the methodology of articles considered excellent for the subject. Only the randomized controlled trials, with adjusted randomization system have been enclosed. All the situations where the researchers didn't agree there was a consensus meeting. It hasn't been stipulated restriction for postoperative period to graft angiographic evaluation, the vessel treated and enclosed patient's characteristics. The results have been expressed as Risk Relative (RR), with 95% of Confidence Interval (CI), to comparison the effectiveness between the radial artery and the saphenous vein. RESULTS: Based in these criteria three studies have been enclosed. We couldn't find statistic difference between grafts' patency studied (RR 0.53 [95% IC 0.13 - 2.18]). CONCLUSION: Despite of the studies have good methodological quality, we have not observed a result significant statistically benefiting one of the grafts. The statistical power of the meta-analysis is low, therefore, it's necessary more randomized controlled trials, with adjusted sample size to detect possible differences between the considered treatments.

    Tempo de compressão da artéria radial pós-cinecoronariografia : influência sobre homostasia e ocorrências de complicações vasculares
    (Universidade Federal de São Paulo (UNIFESP), 2017-11-30) Campos, Maria Aparecida de Carvalho [UNIFESP]; Avelar, Ariane Ferreira Machado [UNIFESP]; Peterlini, Maria Angelica Sorgini [UNIFESP]; http://lattes.cnpq.br/1599622257763420; http://lattes.cnpq.br/8919300907658980; http://lattes.cnpq.br/8700431117009553; Universidade Federal de São Paulo (UNIFESP)
    Transradial access is the safest technique to perform arterial percutaneous diagnostic and interventional procedures. Mechanical devices are used for effective and in shortest time patent hemostasis, increasing late radial artery patency. However, custom dressing gauze compression is widely used in developing countries for cost containment with ideal time for hemostasis, effectiveness of patent occlusion and effect on late radial artery occlusion largely unknown. Objective: We aimed to compare two different compression times of the radial artery after elective coronary angiography using customized compressive dressing regarding the achievement of hemostasis and vascular immediate and late complications. Method: In a prospective, randomized and controlled study in patients submitted to transradial elective coronary angiography, which were allocated to two study groups: compressive dressing maintained for 30 minutes (G30) or compressive dressing maintained for 60 minutes (G60). Variables related to patients, procedure, occurrence of hemostasis and complications were assessed. Radial artery patency was evaluated with Doppler vascular ultrasonography at the time of removal of the compression as well as at 30 days of follow-up. Results: The sample was consisted of 152 patients in the G30 and 151 in the G60, homogeneously distributed in those two studied groups, which have been through demographic, procedural, hemostasis and also vascular complications characteristics. Hemostasis was obtained in 76.3% from the G30 patients and in 84.2% from the G60 patients in the first evaluation. The occurrence of type I and II hematoma was identified in 14.5% from G30 and 20.5% of patients from the G60 while the immediate radial artery occlusion was found in 13.2% from G30 patients and in 11.9% % from the G60. In the 30-day evaluation, 18 late occlusions were identified, 7 (5.5%) from the G30 and 11 (8.2%) from the G60.Conclusion: The different times of radial artery compression after coronary angiography have not significantly influenced the occurrence of hemostasis and vascular immediate and late complications.

    Valor da oximetria de pulso na avaliação da perfusão da mão para retirada da artéria radial: O teste de Allen é satisfatório?
    (Sociedade Brasileira de Cirurgia Cardiovascular, 1998-07-01) Dauar, Renato Bauab; Barros Junior, Newton de [UNIFESP]; Lima, Paulo Ruiz Lucio de; Kyiose, Alberto Takeshi; Leao, Luiz Eduardo Villaca [UNIFESP]; Succi, José Ernesto [UNIFESP]; Hospital Bandeirantes; Universidade Federal de São Paulo (UNIFESP)
    With the increasing utilization of the radial artery as a graft in CABG a reliable evaluation of the integrity of the palmar arch in each patient, is important in order to prevent classically vascular complications of the hand, one uses the Allen test, which is based on a subjective evaluation of the colour change of the hand, when the radial and ulnar pulse are pressed and, therefore, more prone to misinterpretations. For an objective evaluation, we propose this test, analyzing perfusion through pulse oxymetry, a simple method easily available in the operating room.Purpose: The authors present a new proposal to evaluate perfusion and integrity of the palmar arch by pulse oxymetry, comparing information obtained through method with the one obtained through the Allen test.Method: Fifty radial and 50 ulnar arteries from 25 patients in prone position were studied. Patients were 45 years or over, 19 males and 6 females, in stable cardiorespiratory conditions, and free of known peripheral vascular disease in the upper limbs. The oxymeter used was from Ohmeda, and the portable Doppler, with continuous flow from Medical Electronics. At first, the probe was put over the index finger of each hand sequentially observing the saturation level which we called initial. The Doppler was used for the radial and ulnar pulses. The Allen test was performed in each hand, digitally compressing both arteries, with the oxymeter in the second finger, observing the disappearance of the pulse wave. The ulnar artery was then released, causing the return of the pulse wave and obtaining the final saturation. In 96% of cases, there was a drop in saturation ranging from 0 to 2 points. The Doppler probe was located distally to the compression of the radial artery, showing no flow in it.Results: The Allen test proved to be satisfactory (return of colour to the hand in 5 seconds or less) in 35 procedures (70%), and unsatisfactory in 15 of them (30%). The oxymetry was normal in 49 procedures (98%), with an important saturation drop in just one case (2%), in which the Allen test was unsatisfactory.Conclusions: We observed a rather meaningful difference between the results from the Allen test and those from oxymetry, leading one to question the validity of the Allen test regarding its efficacy, since it is a subjective method compared to an objective one (oxymetry). Therefore, we could not be using the radial artery as a graft in 26% of the cases evaluated through the Allen test.
