Song Yan of the Department of Vascular Surgery, First Affiliated Hospital of Zhengzhou University Recently, Associate Professor Song Yan was the chief surgeon who completed a case of resection of a giant abdominal aortic aneurysm and artificial vessel replacement in a senior patient. The patient has been successfully discharged from the hospital. The patient, Ge, male, 62 years old, was found to have abdominal aortic aneurysm in the local hospital and came to our hospital for consultation. The preoperative examination showed that both lungs were combined with chronic inflammation and poor pulmonary ventilation; CTA showed that the aneurysm was located under the renal artery and was severely tilted to the left side, the size of the aneurysm was about 57.7×90.4×50.5mm, a large number of annular low-density shadow was seen around the aneurysm, multiple soft plaques and calcified plaques were formed in the bilateral iliac arteries and abdominal aorta, and the blood flow in both lower limb arteries was slow. On August 16, with the cooperation of the operating room on the first floor, Associate Professor Song Yan overcame the patient’s advanced age, underlying diseases, fluctuating blood pressure and poor physical condition and other high-risk factors, and successfully exposed the abdominal aortic aneurysm via the abdomen, which was measured to be about 70.0 x 100 x 65 mm. The aneurysm was measured to be about 70.0 x 100 x 65 mm, with severe adhesions between the aneurysm and the surrounding tissues. After rapid and accurate resection of the aneurysm, removal of a large amount of attached thrombus and cholesterol plaque, ligation of the lumbar artery, inferior mesenteric artery and median sacral artery, end-to-end anastomosis of the proximal end of the abdominal aorta and both iliac arteries with the Y-shaped artificial vessel was successfully completed in one go, and endothelial debridement of the narrowed bilateral common iliac arteries was performed. After opening the aortic flow, the patient’s bilateral femoral and dorsalis pedis arteries were pulsating well. The patient awoke immediately after the suturing of the abdominal wall incision and returned to the ward. The whole operation went smoothly and the patient’s vital signs were stable without any abnormal bleeding during the operation. All the postoperative vital indicators were within the normal range, and the patient was defecating and ventilating 36 hours after the operation, and was out of bed 48 hours later. At present, the patient has been successfully discharged from the hospital.
