Hence we report a case of bilateral pleural effusion after performing central venous catheterization due to catheter tip migration and abnormal location.
One important test which could have been done to confirm catheter tip migration is by injecting contrast dye through the catheter and take serial radiographs, which was not done in our case.
Thus, we conclude that catheter tip migration is a recognized phenomenon following central venous catheterization and high degree of clinical suspicion and examination is required for early identification of this dreadful complication to avoid devastating outcome.
