The need for dialysis after aortic coarctation surgery may be due to renal failure caused by aortic coarctation or surgical factors.
1. Causes of aortic coarctation: As the largest arterial vessel in the whole body, the aorta is responsible for transporting and shunting arterial blood to various organs and tissues. When aortic coarctation affects other important branch vessels, it often leads to insufficient perfusion to the corresponding organs and tissues. When the entrapment involves one or both renal arteries, it can cause kidney ischemia, and in severe cases, even kidney failure, requiring dialysis treatment.
2. Surgical reasons: Aortic coarctation surgery, as a major surgery, often requires a large amount of blood transfusion during the perioperative period, and the extracorporeal circulation during the replacement of the aorta is relatively long, and all these factors may lead to postoperative renal failure.
The specific situation varies from person to person and the attending physician should also be consulted promptly.
