Today, a patient came to the hospital for review, six months after surgery, the limb function recovery is not good, said to the emotional point, weeping. After careful examination, it was found that many problems that should be paid attention to were not paid attention to, resulting in poor recovery of limb function. Combined with the problems that patients have been responding to in the outpatient clinic, it is necessary to emphasize to you the postoperative precautions, in fact, these matters are explained in detail during the postoperative hospitalization and at the time of discharge, but unfortunately some of the patients forgot all about them after discharge, so that they only remembered when they came for review! Miao Chaofeng, Department of Vascular Surgery, First Affiliated Hospital of Zhengzhou University The most important part of the radical treatment of deep venous valve insufficiency is to perform deep venous valve function reconstruction surgery, which is also known as N vein muscle collaterals, that is, to make muscle collaterals with tendons outside the N vein, and this muscle collaterals play the role of replacing the valve to resist regurgitation and promote reflux during the activity, and the activity becomes the prerequisite for the function of the muscle collaterals. How to move the collaterals to make them work? That is to flex the knee joint, in walking is the action of lifting the leg and flexing the knee, many patients exercise after surgery, often walking with a straight leg, the knee does not bend, then the muscle collaterals do not play a role, it is difficult to restore function, so one of the key points of activity is to lift the leg and flex the knee, of course, the natural walking degree of flexion is enough, do not need to deliberately flex the knee to more than 90 °. The second point is that when walking, the palm of the foot to force, the palm of the foot force, the rear side of the calf muscle group contraction, play the role of “venous heart” to promote venous return, many patients are afraid of pain after surgery, do not dare to have the palm of the foot to force, often use the heel to force, but not less exercise, but the effect is not obvious, the reason is that the force is not the right position, in fact In fact, it can be done with a little attention when walking normally. The more you walk, the more you exercise, the easier your limb will be. On the contrary, the swelling of the limb will not be eliminated obviously, and the feeling of distress and swelling of the limb will increase, which will affect the effect of the surgery and the quality of life. The pain disappeared after 20 minutes. So please take it seriously. In addition, the activities of exercise should not be excessive, some patients a day dozens of kilometers, which is a bit too much, and avoid violence, jumping, squatting, to avoid trauma. As long as the required exercise, limb function can be recovered very well, and the more you use the better, lifelong use! If any problems arise after discharge, it is recommended that you come to the hospital in time for a face-to-face consultation! One is that you can eliminate unnecessary worries, and the second is that if there is really a problem, you can get timely treatment! This article is authorized by Dr. Chaofeng Miao.
