Whether it was a femoral artery thrombectomy or an endarterectomy, both were considered highly dangerous major surgeries. After all, it involved operating directly on blood vessels, especially a major artery like the femoral artery.
There were also two viable methods in thrombectomy: one was direct extraction by incision, and the other involved using a balloon catheter to remove the thrombus. Like an appendectomy, there was conventional open surgery and minimally invasive procedures like laparoscopy.
You couldn't simply say which surgery had a better effect, because it involved evaluation of many aspects, such as the patient's physical condition, surgical costs, and subsequent necessary procedures.
Grandpa Cao also had diabetic foot. The balloon thrombectomy needed to be performed in the DSA operating room, and he also required an endarterectomy.
