This case report describes damage to a pulmonary artery catheter (PAC) during transmyocardial laser revascularization. We observed persistent bleeding and a temperature reading of "too high" from the temperature connection port of PAC during cardiopulmonary bypass while the patient's nasopharyngeal temperature read 34 degrees C. This alerted us to the possibility of PAC damage during creation of laser channels in the right coronary artery territory on the inferior surface of the heart. This is a unique complication related to this coronary revascularization procedure.
We report an unusual case of pulmonary artery catheter (PAC) damage during transmyocardial laser revascularization (TMLR). This observation should alert the anesthesiologist to the fact that the PAC may be damaged when TMLR is performed on the right side of the heart. We recommend that the PAC be withdrawn during this procedure.
本病例报告描述了经心肌激光血运重建术中肺动脉导管（PAC）的损伤情况。在体外循环期间，我们观察到PAC温度连接端口持续出血且温度读数“过高”，而患者的鼻咽温度为34摄氏度。这使我们警觉到在心脏下表面右冠状动脉区域创建激光通道时PAC受损的可能性。这是与该冠状动脉血运重建手术相关的一种独特并发症。
我们报告了经心肌激光血运重建术（TMLR）期间肺动脉导管（PAC）损伤的一例罕见病例。这一观察结果应提醒麻醉医生，在心脏右侧进行TMLR时PAC可能会受损。我们建议在此手术过程中拔出PAC。
