Patient Question: Hello, I have had coronary artery disease for 20 years, I have had a stent, I have been taking anticoagulants for years, and now I have small intestinal gas, I have heard that I tend to bleed on anticoagulants, can I have hernia surgery? Reply: This is a good question. Nowadays, many heart patients are taking anticoagulants all year round, and the majority of them can still have hernia surgery, but the choice of surgery time and the adjustment of perioperative medications vary. The anticoagulants that cardiac patients often take are different. The vast majority of patients take aspirin, which can be used to perform hernia surgery without stopping the medication, despite the fact that it increases bleeding from the patient’s trauma. Some patients without definite coronary artery disease, taking aspirin only for hyperlipidemia, are advised to discontinue aspirin for 3-5 days prior to surgery. Nowadays, many patients with coronary artery disease have stents, and after stents are installed, they will definitely take anticoagulant drugs such as Polivic or Taga for half a year to a year, and the anticoagulant effect of these drugs is stronger than that of aspirin. surgery for hernia. The biggest impact is still warfarin. In fact, apart from hernia surgery, warfarin also has an impact on other surgical procedures. Warfarin has a strong anticoagulant effect and is mainly used for anticoagulation after heart valve replacement to prevent the formation of blood clots in the prosthetic valve. If you do hernia surgery, you need to switch to low-molecular heparin for a few days as a replacement therapy to improve the coagulation index before the surgery can be performed, and then switch back to warfarin after the surgery to overcome the dangerous period of bleeding and bleeding.
