Full Story

Recently, Mr. N (pseudonym), 35 years old, underwent the "largest surgery" in the field of cardiac and vascular surgery at Fuwai Hospital in Beijing, completely removing a "time bomb" in his body that could have caused fatal risks.

Danger strikes suddenly: At 35, he stands at the brink of death due to aortic disease.

In late 2024, Mr. N suddenly experienced severe chest pain that radiated to his abdomen, a tearing pain accompanied by profuse sweating and fainting. He sought medical help at the Third National Hospital in Ulaanbaatar and top private hospitals before his family finally contacted Harbor Health. Harbor Health immediately organized a remote consultation between Chinese and Mongolian doctors, accurately diagnosing him with Stanford Type B Aortic Dissection. After developing a comprehensive plan for stabilizing blood pressure and controlling pain, seamless coordination between Chinese and Mongolian doctors ensured that Mr. N and his family flew to Fuwai Hospital in Beijing, where treatment began immediately.

After a comprehensive examination, Mr. N's condition was found to be far more complex than initially thought: the aortic dissection was extensive, and he had an aberrant subclavian artery malformation, making conventional surgical methods unsuitable. Considering Mr. N's age, and to minimize treatment risks and achieve the goal of a normal life post-surgery, the expert team developed a two-stage surgical plan. The first stage of surgery, a femoral artery-to-femoral artery bypass graft, yielded immediate results: blood supply to his lower limbs was restored, chest and abdominal pain was significantly reduced, blood pressure was stabilized, and the aortic dissection was stabilized. The "time bomb" within Mr. N's body was successfully defused, ensuring his safety for stage 2 surgery.

Multidisciplinary collaboration to customize the " Largest Surgery "

Six months after his first surgery, Mr. N returned to Beijing Fuwai Hospital. Professor Yu Cuntao, director of the Vascular Center, led a specialized team, together with Deputy Director Gao Wei, and invited multiple departments, including the Anesthesia and Surgery Department, Extracorporeal Circulation Group, and Intensive Care Unit, to conduct a joint consultation and tailor a radical surgical plan for Mr. N.

The team used the "total thoracoabdominal aortic artificial blood vessel replacement" technique, which involves opening both the chest and abdominal cavities simultaneously (through an incision about 1 meter long from the armpit to the abdomen) to perform a total thoracoabdominal aortic replacement, solving all problems in one go: replacing the diseased blood vessel with an artificial blood vessel, rebuilding blood supply channels for vital organs such as the heart, stomach, and kidneys, and repairing the intercostal arteries that supply blood to the thoracic vertebrae and ribs, completely defused the "bomb" and restored the blood vessels to normal.

This surgery— total thoracoabdominal aortic artificial blood vessel replacement —is widely recognized as the "crown jewel" and "ultimate challenge" in the field of cardiac and vascular surgery, and can be called the "largest surgery."

The term "large" refers not only to the time length of the surgery and the size of the incision, but also to the technical complexity, the wide range of physiological disturbances, the extreme risks, and the extremely high requirements for the comprehensive capabilities of the medical team.

We can understand why it is called "the largest surgery" from the following key dimensions:

1. The scope and scale of the surgery are enormous.

Extensive anatomical scope: The surgery requires replacing the entire aorta from the thoracic cavity to the abdominal cavity, involving two large cavities , the thoracic cavity and the abdominal cavity , and requires handling anatomical structures passing through the diaphragm.

The aorta is interconnected with many organs: it directly branches off to supply all the important blood vessels to the liver, spleen, stomach, intestines, kidneys, and spinal cord. The surgery must interrupt the blood supply to these organs and perform vascular reconstruction, which is equivalent to performing "vascular bypass" on multiple organs simultaneously.

2. Extremely high technical complexity and precision requirements.

Multivascular reconstruction: During the procedure, the blood vessels supplying the abdominal organs (abdominal cavity, superior mesenteric artery, renal artery) and the spinal cord (intercostal arteries, lumbar arteries) must be reanastomosed to new artificial blood vessels sequentially or simultaneously. The anastomosis of each blood vessel requires precision, no leakage, and no torsion, otherwise it will lead to necrosis of the corresponding organ.

Spinal cord protection: This is one of the biggest technical challenges. The blood supply to the spinal cord is extremely fragile, and intraoperative aortic occlusion can easily lead to spinal cord ischemia, resulting in postoperative paraplegia. Therefore, complex auxiliary techniques are required, such as cerebrospinal fluid drainage, staged distal aortic perfusion, hypothermia, and evoked potential monitoring, which greatly increases the complexity of the surgery.

Limited surgical field of vision: The surgical field of vision is deep, especially when reconstructing abdominal branch vessels. The operating space is limited, which is a huge test of the doctor's skills and endurance.

3. The physiological disturbances are extremely severe.

Risk of massive bleeding: The aorta is the largest artery in the human body and has extremely high pressure. The entire procedure carries the risk of catastrophic bleeding.

Multiple organ ischemia-reperfusion injury: When blood supply to organs such as the liver, intestines, kidneys, and spinal cord is interrupted and then restored, a large amount of toxins and inflammatory mediators are produced, which may trigger systemic inflammatory response syndrome and, in severe cases, lead to multiple organ failure.

Hemodynamic "roller coaster": When the aorta is blocked and re-opened, the patient's blood pressure fluctuates dramatically, posing a top challenge to anesthesia management.

4. Extremely high risk, serious complications.

Mortality rate: Even in top medical centers, the perioperative mortality rate can still be as high as 5%-15% or even higher, which is much higher than that of routine cardiac surgery.

High incidence of serious complications:

• Paraplegia: The most catastrophic complication, with an incidence rate of approximately 2%-10%;

• Acute renal failure: requires dialysis;

• Respiratory failure: requires long-term mechanical ventilation support;

• Intestinal ischemia and necrosis;

• Massive bleeding;

· Infect.

5. It is a systemic test for the medical team.

"Marathon" surgery: usually takes 6-12 hours or even longer, requiring the surgeon, assistants, anesthesiologist, cardiopulmonary bypass specialist, and nursing team to maintain a high level of focus and physical strength.

Multidisciplinary collaboration: It requires seamless collaboration among top experts from multiple departments, including cardiac and vascular surgery, anesthesiology, extracorporeal circulation, intensive care unit, blood transfusion, neuromonitoring, and nephrology.

Perioperative management is complex: Postoperative patients may require monitoring and treatment in the hospital for several weeks, and the management of every aspect, including respiration, circulation, renal function, coagulation, infection, and nutrition, is crucial.

In short, total thoracoabdominal aortic artificial blood vessel replacement is equivalent to replacing the main water supply pipes of an entire building from the top floor to the basement without interrupting water and electricity supply or damaging the building's main structure, while simultaneously connecting new branch water pipes to every floor and every key room.

Therefore, successfully completing a total thoracoabdominal aortic artificial blood vessel replacement surgery represents the highest comprehensive strength of a hospital's cardiac and vascular surgery department and even the entire critical care system. It is the ultimate test of surgical skills, teamwork, and the medical system, representing the most advanced medical capabilities worldwide.

Top-tier team: 8-hour surgery, overcoming multiple challenges

On the day of surgery, Professor Yu Cuntao served as the chief surgeon, with Associate Chief Physician Gao Wei and others working closely together. The anesthesia, extracorporeal circulation, and surgical nursing teams provided full support throughout the procedure.

During the surgery, the doctor first cut off the diseased blood vessel, then carefully separated the various branches of the blood vessel, and then used the method of "segmental anastomosis + protection of organ blood supply" to reconstruct the blood vessel: the upper end of the artificial blood vessel was connected to the descending aorta, the blood vessel wall supplying blood to the thoracic vertebrae and ribs was preserved and connected to the artificial blood vessel, and then the blood vessels supplying blood to the stomach and kidneys were anastomosed to the branches of the artificial blood vessel one by one. Finally, the distal end of the artificial blood vessel was connected to the artery at the root of both legs.

The anesthesia team also faced significant challenges: they not only had to precisely control blood pressure and heart rate, but also monitor urine output and intracranial pressure in real time, reduce the risk of spinal cord ischemia by releasing cerebrospinal fluid, and maintain one-lung ventilation to ensure a clear surgical field while preventing the patient from experiencing hypoxia.

The surgery proceeded smoothly according to the pre-planned procedure, with each step testing the doctor's skill and patience. After eight hours of intense work, the surgery was finally completed successfully.

Rapid recovery: From critical condition to standing, a turning point in life

After the surgery, Mr. N was transferred to the intensive care unit for close monitoring. For him, the successful surgery was only the first step; he still had to overcome several hurdles, including organ damage, awakening, and limb movement.

Pictured: Mr. N, who was discharged from the intensive care unit on the 5th day after surgery.

Fortunately, his recovery progressed far beyond expectations: on the second day after the operation, he was able to have his endotracheal tube removed, breathe independently, and move his limbs normally; on the fifth day after the operation, he successfully left the intensive care unit and returned to a regular ward, which greatly encouraged everyone.

Mr. N has now returned to a normal life. Speaking of his medical experience, he and his family are filled with gratitude and cannot hide their joy at being given a new lease on life.
