经尺动脉途径介入治疗冠心病术后半年平板运动试验评估心功能 总被引:1,自引:0,他引:1
目的:观察经尺动脉途径介入治疗冠心病术后半年平板运动试验对心功能的评估结果,比较经尺动脉途径和经桡动脉途径介入治疗的可行性。方法:在10例患者中应用经尺动脉途径成功7例,其中5例为冠脉造影,2例为支架植入,与经桡动脉途径病例105例进行比较,并对两组患者中接受经皮腔内冠状动脉成形术(percutaneoustransluminalcoronaryangioplasty,PTCA)及支架植入者进行随访,同时应用活动平板运动试验评估患者心功能情况。结果:经桡动脉途径与经尺动脉途径穿刺及导管操作的平均时间犤冠状动脉造影(60±30)min,PCI(83±24)min犦差异无显著性意义。冠状动脉造影及支架植入的成功率经两种途径差异无显著性意义。7例患者中没有并发症发生,术后随访平板运动试验评价的心功能均得到改善。结论:尺动脉可作为另一个可行的冠状动脉诊断和治疗途径,同时可保留桡动脉用于做外科冠脉搭桥。经尺动脉途径介入治疗冠心病后通过活动平板运动试验检测发现,此种术式能显著改善患者术后的心功能。 相似文献

目的分析桡动脉冠状动脉旁路移植术患者血浆血栓调节蛋白(TM)水平与早期预后的相关性。方法将193例桡动脉冠状动脉旁路移植术患者根据术后24 h血浆TM水平分为TM低水平组97例和TM高水平组96例。根据出院6个月心脑血管事件发生情况,将患者分为预后良好121例和预后不良72例。采用ELISA法检测血浆TM水平,分析2组一般资料、手术情况、合并疾病情况及预后情况,分析影响桡动脉冠状动脉旁路移植术患者早期预后的因素。结果与TM低水平组比较,TM高水平组体质量指数(BMI)较高、左室射血分数(LVEF)较低、吸烟史例数较多,差异均有统计学意义(P 0.05)。与TM低水平组比较,TM高水平组合并2型糖尿病、新发及陈旧性心肌梗死例数较多,差异均有统计学意义(P 0.05)。TM高水平组预后良好率低于TM低水平组,差异有统计学意义(P 0.05)。多因素Logistic回归分析显示,TM、新发及陈旧性心肌梗死是影响冠心病患者桡动脉冠状动脉旁路移植术后发生不良预后的独立危险因素(P 0.05),LVEF是影响冠心病患者桡动脉冠状动脉旁路移植术后发生不良预后的保护因素(P 0.05)。结论血浆TM水平与患者术前身体状况有一定联系,TM高水平患者术后不良心脑血管事件发生率高于低水平患者,TM水平变化对评估冠心病患者预后有重要意义。 相似文献

经桡动脉行冠状动脉旁路移植术是目前较为推崇的搭桥手术。桡动脉内膜较薄,血管腔具有很好的收缩性和舒张性,且桡动脉有足够的长度、适中的口径及取材容易,作为冠状动脉搭桥的桥管远期通畅率高。但是,桡动脉肌层较厚,易发生痉挛,取材前后患肢的护理、桥管的保护是手术前后的护理要点.我科2004年5月-2005年1月经桡动脉行冠状动脉旁路移植术16例,均取得良好疗效。 相似文献

传统意义上将循环冠状动脉旁路移植术分为体外和非体外两种。体外循环冠状动脉旁路移植术相对非体外循环冠状动脉旁路移植术风险更低[1]。非体外循环冠状动脉旁路移植术是一种比较复杂且难度比较高的手术,但随着医疗水平的提高,以及医生手术水平的提高,现已成为比较普遍的手术[2-3]。本研究通过对60位进行非体外循环冠状动脉旁路移植术患者术后伤口引流量进行监测。 相似文献

Two cases of catheterization of the pulmonary artery, in which the hemodynamic findings were very different from the initial clinical diagnosis, are presented. The importance of verifying the adequate position and motion of the pulmonary artery catheters with two consecutive chest x-rays is discussed. In particular, attention is brought to the possible misinterpretation that occurs in patients with very elevated pulmonary artery mean pressure. 相似文献

56 radial arteries were cannulated by cutdown technique in 54 critically ill infants (age (mean±SD) 12.2±25.9 days, weight 2710±910 g) for continuous pressure monitoring and repeated blood sampling. 30 patients survived their illness, 24 died. The mean catheterization time in the survivors was 8.1±4.1 in the non-survivors 6.9±5.6 days. Most cannulae were removed electively. 27 of the surviving infants were followed up after 10.5±5.1 months. 25 (86%) vessels were patent, 4 (14%) occluded. No trophic changes of hands or fingers were noted. We conclude that radial artery cannulation by cutdown in infants is a quick and safe technique and is suitable in patients with severe peripheral vasoconstriction. 相似文献

In this case report, ultrasound-guided radial artery catheterization and a modified Allen's test were performed by Emergency Department (ED) physicians to facilitate the management of an intubated, critically injured patient. Ultrasound was demonstrated to be a valuable tool in determining collateral circulation and guiding radial artery cannulation in a patient unable to cooperate with the traditional Allen's test. Ultrasound guidance may reduce the risk of radial artery catheterization in severely injured patients. 相似文献

The combination of a spring guide wire with a sheath introducer system has been successfully used for the routine placement of pulmonary artery and central venous catheters. The method, which is described is simple, quick, and safe. It is applicable to the initial placement of the catheter, to any necessary alterations in its position and to its eventual replacement with a central venous cannula. 相似文献

After two decades, hemodynamic invasive monitoring using a flow-directed, balloon-tipped, pulmonary artery (PA) catheter has established itself as a significant component of acute clinical care. In spite of continued recommendations for limitations, restrictions, moratoria, and even abandonment, growth in catheter use continues. Attempts to replace it by competing technologies for routine clinical practice have not been successful thus far. More than one million PA catheters are inserted in the United States annually. The clinical utility and value of the pulmonary artery catheter depend largely on the interpretation of information obtained. Clinical interpretation of data is influenced by an understanding of cardiopulmonary hemodynamics, technical skills, and professional integrity of the physician using the device. After a brief history, this article focuses on the technical aspects of the insertion procedure, choice of hardware, and acquisition and analysis of information. Indications, contraindications, and clinical utility are briefly described. Major complications from PA catheterization reported in the literature since clinical introduction of the catheter are summarized. 相似文献
