Old Wang, a patient who was in danger of amputation due to re-thrombosis of the artery in his right leg, improved and saved his right leg after a new method of surgical thrombus retrieval combined with interventional treatment by vascular surgery specialists. Lao Wang was seen at a local hospital for sudden coldness and severe pain in his right leg. After examination, the doctor honestly told him: we can no longer do anything, you’d better hurry to Beijing to cure it, late, the leg will not be saved. It turns out that Wang had atherosclerosis thrombosis in his right leg artery three years ago, and he had two operations to remove the embolus and artificial vessel bypass in the local area to save his right leg. Now, the thrombosis occurred again in his leg, and the ultrasound examination found that the artificial blood vessel was full of thrombus, and there was no blood flow in the lower limb, which was more serious than three years ago, and his right leg was at risk of amputation. Old Wang urgently came to our vascular surgery department for consultation. After discussion, the whole department concluded that the reoccurrence of stenosis had led to the formation of thrombus in the artificial blood vessel, causing severe ischemia in the right leg, and according to the previous method, both thrombus removal and artificial blood vessel bypass were needed. However, the patient had a history of two previous surgeries and was of an advanced age, so this procedure was highly traumatic and risky, with a low success rate and potentially life-threatening. In order to save the patient’s right leg and reduce the risk without endangering the patient’s life, the department decided to take advantage of the vascular surgeon’s mastery of both surgical and interventional techniques to improve the traditional surgical method and use a combination of surgical thrombus retrieval and interventional treatment to reduce trauma and solve the problem of stenosis and thrombosis at the same time, striving to achieve good results. Under the premise of elaborate surgical plan and contingency plan, the operation was performed according to the predetermined plan: I first made a small incision in the thigh under local anesthesia, removed all the thrombus through the artificial vessel, and then performed angiography. The angiogram revealed two severe stenoses, which confirmed the preoperative judgment. If the stenoses were not treated, the thrombosis would occur again and everything we had done would be lost. Deputy Director Zhang Wangde decisively implanted stents in the stenosis to open the stenosis and make the “blood path” completely open, and the patient’s leg finally turned from cold to warm.
