We describe a technique to protect the patent internal mammary artery graft from injury by repeat sternotomy.
The internal mammary artery is dissected as far proximally as possible. The left pleural space is opened widely thus allowing the left lung to protrude through the pleural defect once mechanical ventilation is resumed. The left lung is then interposed between the internal mammary graft and the sternum. The internal mammary artery is thereby protected from adherence to the sternum and injury upon resternotomy.
In two patients in whom this technique was employed repeat sternotomy was easily performed without injury to the internal mammary artery.
This simple technique effectively protects the patent internal mammary artery bypass graft from injury at subsequent sternotomy.
我们描述一种通过再次开胸手术保护乳内动脉移植血管免受损伤的技术。
尽可能向近端解剖乳内动脉。广泛打开左胸膜腔，这样一旦恢复机械通气，左肺就能通过胸膜缺损处突出。然后将左肺置于乳内动脉移植血管和胸骨之间。从而保护乳内动脉不与胸骨粘连以及在再次开胸手术时免受损伤。
在采用该技术的两名患者中，再次开胸手术得以轻松完成，且乳内动脉未受损伤。
这种简单的技术能有效保护通畅的乳内动脉搭桥移植血管在后续开胸手术时免受损伤。
