Partial XXXX of the left lower lobe: incidental diagnostic after central venous cannulation.

@entity1 @entity26 @entity358 @entity810
OBJECTIVE: To report a case of partial @entity358 of the left lower lobe diagnosed after central venous cannulation. DESIGN: Retrospective case review. SETTING: Intensive care unit. @entity1 : A 76-yr-old @entity1 with obstructive @entity810 requiring hemodialysis. INTERVENTIONS: Central venous cannulation and hemodialysis. MEASUREMENTS AND MAIN RESULTS: The diagnosis was suggested by chest radiography after placement of a central venous catheter through the left internal jugular vein. Pressure measurements at the tip of the catheter showed a venous waveform. @entity26 blood content on samples of blood was higher than on peripheral arterial blood. Computed tomography with intravenous contrast was not conclusive. Diagnosis was confirmed with transcatheter phlebography. CONCLUSIONS: It is important for the intensivist to be aware of this infrequent variant when a central venous catheter takes an abnormal route and drains low-pressure, arterialized blood.
