PCI surgical procedure steps

PCI is the English abbreviation for percutaneous coronary intervention, a general term for a broad category of minimally invasive procedures used to treat coronary heart disease. These include coronary balloon angioplasty, stent implantation, rotational atherectomy, and thrombus aspiration. Taking stent implantation as an example, the specific procedural steps are as follows:

1. Prior to the procedure, sterilization and draping are performed to ensure the operation takes place in a sterile environment.

2. The physician selects an appropriate site for vascular puncture, typically at the wrist, femoral artery, or femoral vein. A needle and guidewire are used to access the blood vessel.

3. Through the puncture site, a guidewire is inserted and advanced to the target vessel requiring treatment. The physician uses X-ray or other imaging techniques to guide the placement.

4. Under guidewire guidance, the physician advances specialized devices such as a balloon catheter into the narrowed or blocked segment of the vessel. The balloon is then inflated to dilate the vessel and restore blood flow.

5. After vessel dilation, the physician delivers a stent via a delivery system into the treated segment. A stent is a metal mesh structure that expands and supports the vessel wall, preventing re-narrowing or blockage.

6. The stent is deployed and fixed against the vessel wall. This may be achieved by self-expanding stents or with the assistance of a balloon catheter.

7. Imaging techniques are used to verify the stent's position and assess blood flow. Minor adjustments or additional interventions may be performed if necessary to ensure proper stent placement and restoration of blood flow.

8. Upon completion of stent implantation, the guidewire and catheters are carefully removed from the vessel, followed by hemostasis management.

To ensure standardized surgical procedures, patients are advised to seek treatment at正规 medical institutions under the guidance of qualified physicians.
