These treatments include:</p><ul><li>Dissolving a blood clot with medicine</li><li>Opening a partially blocked artery with a balloon</li><li>Placing a small tube called a stent into an artery to help hold it open</li></ul><p>After the x-rays or treatments are finished, the catheter is removed. Pressure is applied to the puncture site for 20 to 45 minutes to stop the bleeding. After that time, the area is checked and a tight bandage is applied. The arm or leg where the needle was placed is most often kept straight for another 6 hours after the procedure.
