Abstract
During IMA harvesting in CABG surgery, the pleura might be kept closed or it may be opened. The purpose of this study was to compare the early postoperative course of two randomized groups of patients who underwent IMA harvesting with or without pleurotomy for myocardial revascularization as regard the early outcomes including pulmonary functions and pulmonary complications. One hundred patients with ischemic heart disease for CABG were included. The patients were randomized and divided into 2 groups:The first group: included 50 patients with preservation of the pleural integrity (closed pleural technique) (group I)The second group: included 50 patients without preservation of the pleural integrity (open pleural technique) (group II).This study was done between august 2016 and august 2017 in cardiothoracic surgery department in Mahalla cardiac Center. There was no statistical difference between the two groups preoperatively regarding their age, sex, co-morbidities and risk factors of the patients, the echocardiographic assessment of the cardiac functions, preoperative pulmonary function tests and ABGs.Regarding intra-operative comparison, there was no significant difference between the two groups in the number of grafts, bypass time and cross clamp (ischemic) time.
