Complications of lower extremity varicose vein surgery depend on the type of surgery, which is mainly categorized into traditional and minimally invasive surgical methods. The postoperative complications are different between the two, as explained below: In traditional surgery, there may be infection of the surgical incision, subcutaneous bruising, etc.; peroneal nerve damage caused by the surgery may result in numbness of the skin and other sensory disorders; traditional surgery may result in longer bed rest, which is prone to the formation of thrombus in the deep veins of the lower limbs; the surgery may result in the leakage of fluids in the veins, which may lead to the swelling and pain of the limbs. If a minimally invasive surgical approach is taken, postoperative complications mainly include the formation of superficial phlebitis, the formation of deep vein thrombosis, and postoperative recurrence. After surgery for varicose veins of the lower extremities, you should pay attention to observation and take appropriate treatment and rehabilitation care as prescribed by the doctor. For varicose veins in other parts of the body, there are also complications associated with the surgery, which are not repeated.
