Because of the close anatomic relationship of the pericardium, diaphragm, and peritoneal cavity, a benign pneumoperitoneum may occur following median sternotomy incision and cardiac surgery. The pneumoperitoneum results from inadvertent opening of the peritoneal cavity during the initial surgical incision or during the subsequent cardiac surgery. It is generally of no significance to the patient, although it must be distinguished from pneumoperitoneum occuring secondary to intraabdominal pathology or to retrograde dissection of extraalveolar air in patients on ventilatory support. Two illustrative cases are presented.
由于心包、膈肌和腹膜腔之间存在紧密的解剖关系，正中胸骨切开术和心脏手术后可能会出现良性气腹。气腹是在初次手术切口或随后的心脏手术过程中意外打开腹膜腔所致。尽管必须将其与继发于腹腔内病变或通气支持患者肺泡外空气逆行剥离所致的气腹相区分，但它通常对患者无显著影响。本文介绍了两个示例病例。
