- There is a small chance that the catheter may damage a blood vessel or dislodge a piece of clotted blood or fat from the vessel wall. The clot or fat can block blood flow to the brain, arm, leg, or intestine (bowel).
- Bleeding from the needle site may occur. Also, a blood clot can form where the catheter was inserted. This may cause some blockage of the blood flow in the arm or leg.
