Recently, a woman had persistent edema after mastectomy and axillary lymph node dissection, especially her left hand was so swollen that she could not lift it and even had difficulty getting dressed. Guan Guan, a plastic surgeon at Hsinchu Branch of National Taiwan University Hospital, said that the symptoms of patients are caused by lymphedema, which mostly occurs in cancer patients who have undergone lymph node surgery or lymph node dissection, including breast cancer and cervical cancer, especially breast cancer patients. The incidence rate is as high as 49%. The cause of lymphedema comes from the destruction of the lymphatic system, which leads to poor circulation of the lymphatic system, so that protein-rich lymph accumulates in the limbs of the body, thus causing swelling. Patients with lymph node surgery or lymph node dissection have a higher incidence. Data show that the incidence of lymphedema after total mastectomy is as high as 49%. Dr. Guan said that in the past, lymphedema was treated conservatively. By wearing compression suits, blood vessels were prevented from dilating and the oppression on the affected limbs was reduced, but the effect was quite limited, and edema was often repeated or even aggravated. With the development of microsurgery technology in recent years, lymphatic vein anastomosis and lymphatic transplantation can be used for treatment. After the operation, the edema of the patient's hand was obviously improved by continuous * * *. Microsurgery can increase the technical feasibility of anastomosis of small blood vessels or lymphatic vessels, such as blood vessels with a diameter of 0.5mm~0.8mm, which can be anastomosed by ultra-microsurgery. Guan said that in recent years, the new direction of lymphedema treatment is to drain the blocked lymph, reflux the venous system and transplant the lymph node flap to achieve the improvement effect, and the technology is better than before.
