Cardiac CT for intraseptal pseudoaneurysm: impending double rupture of ventricular septum and left ventricular free wall.

A 71-year-old woman presented at our hospital with chest discomfort. Cardiac CT showed an impending double rupture; an intraseptal pseudoaneurysm had ruptured into the right ventricle, while the left ventricular free wall remained intact at this stage. After admission, the patient fell into cardiogenic shock.

The relative trending accuracy of noninvasive continuous hemoglobin monitoring during hemodialysis in critically ill patients.

The pulse CO-Oximeter (Radical-7; Masimo Corp., Irvine, CA) is a multi-wavelength spectrophotometric method for noninvasive continuous monitoring of hemoglobin (SpHb). Because evaluating the relative change in blood volume (ΔBV) is crucial to avoid hypovolemia and hypotension during hemodialysis, it would be of great clinical benefit if ΔBV could be estimated by measurement of SpHb during hemodialysis.
