Back pain after aortic coarctation surgery may be caused by postoperative recurrence, discomfort caused by the stent in the blood vessel, and prolonged bed rest. Postoperative recurrence of aortic coarctation may be caused by poor quality of blood vessels or poor control of blood pressure, etc. If severe tearing pain in the back reoccurs after the operation and is accompanied by cold sweating, pallor, low blood pressure, or even shock, this indicates that there may be a possible recurrence of arterial coarctation after the operation. Discomfort caused by the stent in the blood vessel is usually due to a heavy psychological burden, or the stent is large in size and stretches out in the blood vessel causing vascular discomfort, or an inflammatory reaction of the blood vessel, which leads to the above mentioned conditions. As aortic coarctation surgery usually takes a long time, the back muscles may be sore after the surgery due to lying down for a long period of time, or the back muscles may be compressed if you lie in bed for a long period of time without proper exercise after the surgery, which may lead to the above situation. When back pain occurs after aortic coarctation surgery, you should go to a medical institution in time to improve the examination and clarify the cause, and follow the doctor’s instructions to receive standardized treatment.
