ABSTRACT
A recent study evaluated the effect of pleurotomy for harvesting internal thoracic arteries (ITAs) on pulmonary complications after coronary artery bypass grafting (CABG). Fifty consecutive patients with pleurotomy (group I) were studied retrospectively and compared with a control group of fifty patients undergoing CABG without pleurotomy during ITA harvest (group II). Group I was divided into two groups; forty patients using left ITAs with left open pleurotomy (group Ia), and ten patients using bilateral ITAs with bilateral open pleurotomy (group Ib). On the other hand, group II includes 22 patients without pleurotomy (group IIa) and 28 patients with closed pleurotomy (group IIb). In group I, ITAs were dissected from the chest wall with mediastinal pleura and then isolated from the pleura by pleurotomy. Before sternal closure, an L-shaped pleural tube was inserted into the deep costophrenic sinus and the pleurotomy remained open. In group II, ITAs were simultaneously dissected from the chest wall and mediastinal pleura, and if the pleura was damaged, the pleurotomy was approximated before sternal closure. There was no significance in the number of bypass grafts, aortic crossclamp time, cardiopulmonary bypass time and temperature. ITA harvest time with open pleurotomy was shorter than that of closed pleura (15min versus 25min). Postoperatively, the ventilation time and duration of chest drainage also showed no significance, however group Ia and Ib showed significantly more fluid accumulation removed by chest drainage (Ia, 288±193ml; Ib, 285±198ml, versus IIb, 169±98ml). On postoperative day 30 no pleural effusion was observed in group I but it was seen in one case in group IIb which had diaphragm paralysis. In conclusion, open pleurotomy results in minimal pulmonary complications with optimal chest drainage and offers significant advantages for harvesting ITAs.
