Implication

Comparative study reveals higher pulmonary complication rates following internal mammary artery harvesting with pleurotomy, indicating that preserving pleural integrity protects lung function.

Key Points

To evaluate the incidence and etiology of postoperative pulmonary complications associated with internal mammary artery grafting, focusing on the impact of pleural incision during graft harvesting.
Assessed 106 consecutive cardiac surgery patients categorized into control patients receiving vein grafts or valve replacements (Group I, n=39), patients undergoing internal mammary artery grafting with pleurotomy (Group II, n=34), and patients undergoing internal mammary artery grafting with intact pleura (Group III, n=33).
Evaluated diaphragmatic movement, left hemidiaphragm position, and pleural fluid through inspiration and expiration chest radiographs over a 3-month convalescence period.
Prior to hospital discharge, normal chest X-rays were documented in 69% of control patients (Group I), 42% of intact pleura patients (Group III), and only 9% of pleurotomy patients (Group II).
Internal mammary artery grafting was associated with increased incidences of pleural effusions, left lower-lobe atelectasis, and left hemidiaphragm elevation relative to controls.
At 3 months, 53% of patients with opened pleura (Group II) exhibited persistent loss of left-lung volume from left lower-lobe atelectasis, pleural effusions, and organized hemothorax.
