The Department of Cardiothoracic Surgery successfully performed another arch-descending aortic aneurysm resection and artificial vessel replacement. Recently, our cardiothoracic surgery department successfully performed aneurysm resection and artificial vessel replacement of the descending aorta for a patient who had a descending aortic dissection with pseudoaneurysm formation in the arch-descending region. The patient has successfully recovered and was discharged from the hospital yesterday. This is the third successful case of the same kind in our cardiac surgery department after 2002 and 2004, all of which were done independently. In the past 15 years of medical literature in mainland China, there are few reports of successful surgical procedures in similar cases in other hospitals. Based on the successful surgical experience of these three consecutive cases in our hospital, the unconventional surgical pathway and right heart partial diversion technique used in the newest case is a classic procedure. This 28-year-old male patient surnamed Huang, a cab driver, was unfortunately involved in a rear-end car accident in the early morning of January 18, and hit his forehead on the steering wheel and his head on the windshield, and was sent to a hospital in the city immediately after his injury. The patient was diagnosed with a dissection of the descending aorta with pseudoaneurysm formation in the arcuate descending region, myocardial contusion, contusion of both lungs, hemothorax on the left side, fracture of the right femur, cranial trauma, concussion, soft tissue contusion of the skin on the right frontal face. The patient’s condition was critical, and the doctor on duty quickly contacted Dr. Guofang Zhao, the chief physician. After listening to his condition, Zhao Guofang immediately directed emergency treatment, contacted the blood bank to prepare blood, and notified the operating room and anesthesia department to prepare for emergency surgery. At noon that day, the patient was admitted to the operating room. With the close cooperation of anesthesiologist Hu Xukai, extracorporeal circulation Dong Caijun and other doctors, Dr. Zhao Guofang successfully completed this operation mentioned above by using unconventional surgical pathway and right heart partial diversion technique based on the experience learned abroad. After the operation, Mr. Huang recovered smoothly under the close supervision of the ICU ward and was then transferred to the general ward, during which he completed a series of operations in ophthalmology and orthopedics and finally recovered and was discharged from the hospital yesterday. Pseudoaneurysm of the descending aortic arch is a vicious condition, and the cause is mostly blunt impact injury. Most of the patients die of hemorrhage before reaching the hospital, only about 10% of them can reach the hospital alive, and 90% of those who reach the hospital alive will die of secondary hemorrhage if they are not operated in time. As time passes, the patient’s chances of survival gradually decrease. Therefore, diagnostic examinations and life-saving surgeries often require close cooperation between the relevant departments, and the time is lost. The operation needs to be performed under extracorporeal circulation, and due to the special location of the descending aortic arch, the complexity of the operation is determined, and if necessary, the operation needs to be completed under deep hypothermia and stop circulation. The intraoperative blockade of the descending aorta is necessary, resulting in possible postoperative paraplegia. For these reasons, foreign literature has reported a 25-30% surgical mortality rate and a 15% paraplegia rate in these patients. Dr. Guofang Zhao believes that the unconventional surgical pathway and right heart partial diversion technique adopted in one of our new cases is clearly revealed, convenient and safe for extracorporeal circulation and surgical operation, and less prone to serious complications such as paraplegia, especially for hospitals in China that do not have conditions for femoral artery-femoral vein diversion. The successful implementation of three consecutive cases of this type of surgery in cardiac surgery also marks the comprehensive strength of our hospital in emergency medicine, imaging, anesthesia and monitoring.
