5. Study Description
Brief Summary
the aim of this study is to evaluate safety and efficacy of multivessel minimally invasive coronary artery bypass graft surgery through evaluating the possibility of reaching complete revascularization , the complications during surgery and the outcomes
Detailed Description
Minimally invasive direct coronary artery bypass (MIDCAB) grafting can achieve adequate coronary artery revascularization in a less invasive manner than conventional coronary artery bypass grafting (CABG). Bypass from the internal mammary artery (IMA) to the left anterior descending coronary artery (LAD) is an effective technique for the treatment of simple anterior descending artery disease. This surgery is especially recommended for patients with multiple lesions that are not suitable for stent stenosis . One of the main advantages of MIDCAB is that there is no need for cardiac arrest and cardiopulmonary bypass (CPB) transfer during surgery . MIDCAB patients also benefit from the neurological protection associated with this minimally invasive procedure . Unlike traditional revascularization techniques, which are highly invasive due to the use of a large incision (sternotomy) and cardiopulmonary bypass (CPB), MIDCAB limits invasiveness by operating through a small incision (thoracotomy) and by operating on the beating heart to avoid the need for CPB . By limiting invasiveness in these ways, MIDCAB can reduce the risk of complications such as infection and stroke . In comparison to traditional CABG and off-pump CABG (via a sternotomy), MIDCAB can enhance early post-operative quality of life and recovery time . Minimally invasive multivessel coronary surgery-coronary artery bypass grafting (MICS-CABG) through a small thoracotomy has many advantages over minimally invasive direct coronary artery bypass (MIDCAB). First, MIDCAB is limited to a single anastomosis of the left internal mammary artery to the left anterior descending artery (LIMA-LAD). The surgical exposure of MICS-CABG is done more laterally, leading to reduced risk of costochondral or rib injury. Also, MICS-CABG allows revascularization with a similar configuration to that of a traditional sternotomy technique, by direct-vision LIMA harvesting and hand-sewn proximal and distal anastomoses . MICS may be performed with or without cardiopulmonary bypass (CPB) assistance, but the use of femorofemoral CPB in multivessel revascularization has shown to be safe, mitigate the learning curve, prevent conversions, and allows operative time like that of a sternotomy. ]. Other advantages include a diminished need for blood transfusion, decreased surgical site infection rates, also early return to full physical function .
On the other hand complications include sternotomy conversion and development of left-sided pleural effusion . Postoperative pain can be an issue early, but it is transient, controllable, and significantly decreased by the third postoperative day; it is also associated with an overall improved postoperative pain picture with improved pulmonary functions . However, unlike sternotomy patients, MICS-CABG patients have no physical restriction postoperatively, which leads to better independence.
This study aim to evaluate Safety and efficacy of multivessel minimally invasive coronary artery bypass graft surgery through measuring several factors such as
measuring rate of intraoperative complications occurrence
measuring rate of intraoperative conversion to open sternotomy
measuring amount of post operative bleeding
measuring post operative pain
measuring rate of reexploration
measuring rate of wound infection
calculating days of postoperative hospital stay
calculating time to regain normal activity
The information gathered from the eligible patients will be entered into a data sheet containing the variables of interest that will be analyzed later at the end of the study. This study will not alter the patients' treatment and follow up at our center, by any means.
The following variables will be studied whenever applicable and whenever they are available in the patients' charts:
Demographic data: (Medical Record Number ,Sex ,Age Other comorbidity)
Preoperative variables : (chest pain , dyspnea ,ECG findings ,Myocardial markers and cardiac troponin ,Cardiac Angiography )
Operative variables: (Conversion to sternotomy. , Cardiac arrest ,Operation time ,Need for IABP, CPB ,Need for blood transfusion)
Postoperative variables: (Mortality , Bleeding , Pain , Need of reexploration , Hospital stay , Wound infection , Regain of normal activity , Relief of symptoms , Need for another revascularization within 6 month)
