Off-pump coronary artery bypass (OPCAB), or beating-heart surgery, is a form of coronary artery bypass graft (CABG) surgery performed without cardiopulmonary bypass (heart-lung machine) as a treatment for coronary heart disease. It was primarily …

Coronary artery bypass surgery (CABG) is a type of heart surgery. Surgeons do this type of surgery to bypass blockages in the coronary arteries. An off-pump CABG is a CABG done without the use of a heart-lung machine (cardiopulmonary bypass). This means the heart continues to send blood to the rest of the body during the surgery.

Mar 12, 2007 · “Off-pump” or "beating heart" coronary bypass surgery, also known as OPCAB (for "Off-Pump Coronary Artery Bypass), differs from conventional Coronary Artery Bypass Grafting (CABG) in that the cardiopulmonary bypass pump (extracorporeal circulation) is not employed.

Dec 15, 2021 · OPCAB是在跳动的心脏上进行冠状动脉重建术。 OPCAB对高危患者更有利，如脑，肾，肺功能不全或高龄（>80岁）的患者，可以避免CPB不良影响。 升主动脉粥样硬化患者因不必钳闭主动脉可能从OPCAB中受益更多。 OPCAB的禁忌证主要是局限于技术考虑，如难以解剖的心肌内冠状动脉，心脏操作中腔内血栓的脱落，及瓣膜置换的联合手术。 有恶性室性心律失常的病史，以及无法耐受心肌缺血的患者均不适合OPCAB（表5.1）。 表5.1 传统的CABG和OPCAB …

opcab最大的优势之一，即消除了cpb中血液与体外循环管道接触、全心缺血-再灌注损伤和非搏动性血流。其缺血再灌注损伤仅局限于冠脉移植局部和心脏固定器放置区域，从而减轻全身炎症反应、降低sirs发生率[5]。

Unlike traditional CABG where the anesthesiologist plays a passive role during the performance of bypass grafting, involvement of the anesthesia team is essential for successful OPCAB. A continuous cardiac output swan ganz catheter and continuous mixed …

Aug 14, 2018 · Off‐pump coronary artery bypass surgery (OPCAB) has been performed for >30 years. The promotion of OPCAB was based on its potential benefits over some of the limitations of traditional on‐pump coronary artery bypass surgery (ONCAB) by avoiding the trauma of cardiopulmonary bypass (CPB) and by minimizing aortic manipulation.

Mar 16, 2004 · Successful OPCAB surgery depends on the optimization of cardiac positioning to access target coronary vessels, cardiac stabilization to dampen local cardiac wall motion around the distal anastomotic site, and techniques directed at minimizing myocardial injury from the interruption of coronary perfusion while adequately visualizing the distal an...

Purpose: Off-pump coronary arterial bypass grafting (OPCAB) has become a common practice for coronary artery bypass grafting (CABG) in Japan, with approximately 65% CABG procedures currently being performed using OPCAB.

非体外循环 冠状动脉搭桥术 是外科医生在跳动的、无体外循环支持的心脏上手术。 随着心外科技术的日益成熟,与传统CPB相比,具有缩短手术时间、减少住院和ICU停留时间,避免了体外循环给人体造成的不良影响及相关并发症和降低医疗费用等诸多优点由于心脏手术的大部分并发症与体外循环的应用相关，与传统冠脉搭桥手术相比，非体外循环 冠脉搭桥术 就是不用体外循环在正常跳动的心脏上完成搭桥手术，避免了大部分的并发症、降低了手术风险。 所以 手术技术要求相对 …
