ENProfessor Randolph Hung-leung Wong is Professor and Chief of the Division of Cardiothoracic Surgery at The Chinese University of Hong Kong (CUHK), Cluster Service Team Head of Cardiothoracic Surgery for the New Territories East Cluster, and a cardiothoracic surgeon at the Prince of Wales Hospital and CUHK Medical Centre in Sha Tin. His clinical work focuses on complex aortic surgery, including total aortic arch replacement, the frozen elephant trunk procedure and open thoracoabdominal aortic repair.
🎓 Professional background
[ edit ]Professor Wong entered CUHK's medical school in 1995, received the Tang Siu Cho Memorial Prize in 1998 and graduated with an MBChB in 2000. He completed higher surgical training in cardiothoracic surgery at the Prince of Wales Hospital, Grantham Hospital and Queen Elizabeth Hospital, and obtained his FRCSEd (Cardiothoracic Surgery) from the Royal College of Surgeons of Edinburgh in 2008. In 2009 he was made a Fellow of the College of Surgeons of Hong Kong and a Fellow of the Hong Kong Academy of Medicine (Surgery).
He is currently Secretary of the Cardiothoracic Surgery Board of Hong Kong, a Councillor of the College of Surgeons of Hong Kong, and a Fellow of the American College of Chest Physicians and the European Association for Cardio-Thoracic Surgery. He has also served as Chairman of the Hospital Authority's Specialty Group in Cardiothoracic Surgery.
🫀 Clinical focus: why aortic surgery is difficult
[ edit ]Coronary bypass and valve replacement are relatively standardised procedures. Aortic surgery is different: the difficulty lies in location and extent. The ascending aorta, the arch, the descending aorta and the thoracoabdominal segment each require different strategies for controlling blood flow and protecting organs. When disease extends from the heart's outlet into the abdomen, the surgeon must balance cardiopulmonary bypass, hypothermic circulatory arrest and organ perfusion.
His listed interests map onto that ladder of difficulty:
- Total aortic arch replacement: reconstructing the arch and the three vessels that supply the brain.
- Frozen elephant trunk: placing a stent graft in the descending aorta at the same operation, so that later disease can be treated endovascularly and a second open chest may be avoided.
- Open thoracoabdominal aortic surgery: repairing aneurysms that extend into the abdomen, with protection of the spinal cord and abdominal organs.
- Hybrid thoracic aortic intervention: combining open surgery with endovascular stent grafts, often for older patients or those with other major conditions.
- Minimally invasive and hybrid cardiovascular procedures: completing selected procedures through smaller incisions to reduce trauma and speed recovery.
He convenes the Hybrid Operating Theatre management committee at the Prince of Wales Hospital. A hybrid theatre allows surgeons and interventional radiologists to perform open and endovascular work in the same room without moving the patient, so a plan can be adjusted according to what is found during the operation.
📈 Surgical outcomes
[ edit ]His outcomes are published at team level, and that distinction matters: aortic surgery is delivered by cardiothoracic surgeons together with anaesthetists, intensivists, radiologists and perfusionists.
- New Territories East aortic team: handles 70 to 80 aortic operations a year. Mortality has fallen from about 30 per cent before 2009 to 4.3 per cent, using selective cerebral perfusion that keeps blood flowing to the brain while body temperature is held at 25 to 28 degrees Celsius.
- Total arch replacement with frozen elephant trunk (TAR FET): the CUHK team has performed more than 140 arch replacements over a decade. In the early phase of adopting TAR FET, operative mortality was held at 9 per cent, below comparable international figures; two decades ago mortality for similar operations could reach 20 per cent.
- Novel hybrid stent graft: a one-stage hybrid approach for multi-segment thoracic aortic disease achieved 0 per cent operative mortality in 25 patients, with bleeding, stroke and spinal cord injury described as rare.
These figures describe the results of a hospital cluster and a research team, not an individual surgeon's personal record. Case mix, patient age and severity vary, and the numbers change over time. Their value for patients is to show the general range of risk and technical capability, not to rank doctors. Individual risk still has to be assessed by the treating team.
🔬 Research
[ edit ]His research follows his clinical work: improving outcomes in complex aortic procedures, screening for thoracic aortic aneurysm, the genetic basis of aortic disease, and hybrid endovascular intervention. He has published more than 150 peer-reviewed papers in journals including Circulation, the Journal of the American College of Cardiology, CHEST, the Journal of Thoracic and Cardiovascular Surgery and the Annals of Thoracic Surgery, together with eight book chapters and more than 140 invited lectures. He is a review editor for Frontiers in Cardiovascular Medicine and reviews regularly for CHEST, HEART and several cardiothoracic journals.
🏥 Where to consult
[ edit ]Professor Wong works across the CUHK Faculty of Medicine, the Prince of Wales Hospital and the CUHK Medical Centre. The CUHK Medical Centre is at 9 Chak Cheung Street, Sha Tin, and its cardiothoracic clinic can be reached at 3946 6888. Holding both university and hospital appointments is normal in a teaching hospital: the same doctor teaches, researches and treats public and private patients.
The difference between the public and private routes lies mainly in waiting time, ward class and billing, not in the surgeon. Before booking, confirm which system you are entering, who will operate, and how fees are structured.
📋 Preparing for a consultation
[ edit ]- Imaging discs: the original CT or MRI files, not just the written report.
- Previous reports: echocardiograms, ECGs and any earlier operation records.
- Medication list: anticoagulants, blood pressure drugs and supplements, which matter especially in aortic disease.
- Symptom timeline: where the pain is, when it starts, how long it lasts and what makes it worse.
- Family history: aortic aneurysm and dissection can run in families.
❓ Frequently asked questions
[ edit ]Q: Does an aortic aneurysm always require surgery?
A: No. Treatment depends on size, growth rate, location and symptoms; some patients are monitored with regular imaging. The decision is made by the surgical team for each case. This article cannot replace medical advice.
Q: How does the frozen elephant trunk differ from conventional surgery?
A: It replaces the arch and places a stent graft in the descending aorta during the same operation, so later disease in that segment may be treatable with an endovascular procedure rather than a second open operation. Suitability depends on the extent of disease and the anatomy of the vessels.
Q: Public or private hospital?
A: The main differences are waiting time, ward class and cost, not the surgeon's qualifications. Acute aortic dissection is an emergency and needs immediate attendance at an emergency department; a chronic aneurysm can be planned according to condition and budget.
Q: Is minimally invasive surgery always possible?
A: Some cardiovascular procedures can be done minimally invasively or as hybrid procedures, but complex reconstruction of the arch and thoracoabdominal aorta may still require open surgery. The choice depends on where the disease is, not on preference alone.
