[Bleeding from the optical module connection port of a pulmonary artery catheter]

A 91-year-old man underwent aortic valve replacement using a pulmonary artery catheter (PAC). Intraoperative hemodynamic monitoring with the PAC showed no abnormality except for bleeding from optical module connection port. In the intensive care unit, difficulty in withdrawing the PAC was noted. Surgical removal of the PAC was performed, revealing the PAC sutured to the right atrium. When bleeding from the PAC connection ports is noted, it is advisable to suspect that the PAC might have been sutured.
