The anatomy of the subclavian region may lead to complications when a central catheter is introduced via the subclavian vein.Because the pleura covering the apex of the lung lie just deep to the subclavian vein,a pneumothorax may develop.This may be difficult to detect clinically,and thus a chest radiograph (if possible with the patient in an upright position and in expiration)should be obtained whenever insertion of a subclavian catheter has been attempted.Another complication is perivascular CVP catheter placement,which may result in ectopic infusion of fluid into the mediastinum or pleural space.This diagnosis should be suggested if there is rapid development of mediastinal widening or pleural effusion after CVP catheter insertion.Other complications include inadvertent puncture of the subclavian artery,air embolism,and injury to the phrenic nerve.
