Recently, a groundbreaking procedure was successfully carried out at Hunan Xiangya Hospital, where experts from the Department of Vascular Surgery and Radiology used 3D printing technology to perform an abdominal aortic aneurysm (AAA) surgery on an elderly patient. This marks the first time that 3D printing has been applied in the clinical field of vascular surgery in China, offering a more precise and effective approach to surgical planning.
At the end of May this year, Mr. Wen, an 80-year-old man, was diagnosed with an abdominal aortic aneurysm at the hospital, and his condition was extremely critical. According to Dr. Huang Jianhua, head of the vascular surgery department, the normal diameter of the abdominal aorta is about 2 cm. However, due to continuous expansion, the patient’s aorta had grown to 6 cm, making it highly susceptible to rupture. If the aneurysm ruptured, it could be life-threatening, often leading to rapid death if not treated immediately.
Dr. Huang pointed out that traditional treatment methods for this condition are often invasive and result in slow recovery. To address this, the vascular surgery team at Xiangya Hospital collaborated with a 3D printing company. They refined the CT scan data to obtain accurate spatial information, which was then converted into a 3D model. Using 3D printing technology, they created a detailed, proportional replica of the patient’s abdominal aortic aneurysm and surrounding blood vessels.
"With 3D printing, doctors can fully understand the size, length, shape, and angle of the aneurysm before the operation," said Dr. Huang. "This helps in selecting the right stent, designing the surgical plan, and anticipating potential challenges during the procedure. It significantly improves the accuracy and safety of the surgery."
Recently, the hospital's vascular surgeons successfully performed the AAA surgery under the guidance of 3D printing technology. Experts believe that this innovative approach eliminates the guesswork involved in traditional preoperative planning, allowing for more precise and tailored surgical strategies. The use of 3D printing not only enhances the surgeon's understanding of complex anatomy but also reduces the risk of complications and improves patient outcomes.
