Genicular artery embolization is a minimally invasive procedure performed by endovascular specialists to alleviate knee pain caused by conditions like osteoarthritis. Here’s a brief overview of how this procedure is typically conducted:
- Before the procedure starts, the patient is positioned on an examination table, and their vital signs are monitored. Local anesthesia is administered to numb the area around the groin or wrist, where the catheter will be inserted.
- Using fluoroscopy guidance, the endovascular specialist inserts a thin, flexible catheter into the femoral artery in the groin or radial artery in the wrist. The catheter is then carefully navigated through the arterial system to reach the genicular arteries in the knee joint.
- Once the catheter is positioned near the target area, contrast dye is injected through the catheter, and X-ray images (angiograms) are taken to visualize the genicular arteries and identify any abnormalities or areas of concern.
- After identifying the problematic blood vessels supplying the knee joint, the endovascular specialist uses tiny embolic particles or coils to block or reduce blood flow to these arteries. This process is known as embolization and helps alleviate pain by reducing inflammation and nerve stimulation in the knee joint.
- Once the embolization is complete, the catheter is removed, and pressure is applied to the insertion site to prevent bleeding. The patient is then observed for a short period before being discharged with post-procedure instructions.
According to excellent osteoarthritis knee treatment Phoenix specialists, genicular artery embolization is a very promising treatment option for individuals suffering from chronic knee pain who may not respond well to traditional therapies. As a minimally invasive procedure, it typically involves shorter recovery times and fewer complications compared to traditional open surgeries.
