You may ask for medicine to help you relax (sedative) if you need it.</p><ul><li>During the test, your blood pressure, heart rate, and breathing will be checked.</li><li>The health care provider will shave and clean the groin. A numbing medicine (anesthetic) is injected into the skin over an artery. A needle is inserted into an artery.</li><li>A thin flexible tube called a catheter is passed through the needle. It is moved into the artery, and up through the main vessels of the belly area until it is properly placed into a mesenteric artery. The doctor uses x-rays as a guide. The doctor can see live images of the area on a TV-like monitor.</li><li>Contrast dye is injected through this tube to see if there are any problems with the blood vessels. X-ray images are taken of the artery.</li></ul><p>Certain treatments can be done during this procedure. These items are passed through the catheter to the area in the artery that needs treatment. These 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 leg where the needle was placed is most often kept straight for another 6 hours after the procedure. You should avoid strenuous activity, such as heavy lifting, for 24 to 48 hours.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>How to Prepare for the Test</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
