Transient right hemidiaphragmatic paralysis following subclavian venous catheterization: Possible implications of anatomical variation of the phrenic nerve -a case report-

Phrenic nerve paralysis is an unusual complication associated with central venous catheterization. Various mechanisms have been proposed. We present a case of transient right hemidiaphragmatic paralysis after subclavian venous catheter-ization. We hypothesize that anatomical variation of the phrenic nerve was responsible for this complication.
