Vascular · Endovascular · General Surgery — Singapore
One visit. One surgeon. One plan.
The surgeon who reads your vascular scan is the surgeon who explains the findings, plans your treatment, and carries out the procedure when one is needed.
The one-stop model
Specialist Vascular, Endovascular & General Surgeon
Consultation, duplex ultrasound and treatment planning in a single visit — minimally invasive care, from clinic procedures under local anaesthesia to complex multi-level arterial and venous angioplasty and aortic repair at Singapore’s major private hospitals.

Clinical focus
Conditions treated
Venous disease
Varicose Veins
Bulging, aching leg veins caused by faulty valves. Modern treatment is walk-in, walk-out — usually without surgery in the traditional sense.
Arterial disease
Aortic Aneurysm & Dissection
Silent enlargement or a sudden tear of the body’s main artery. Screening is simple; modern repair is often through two small groin punctures.
Venous disease
Deep Vein Thrombosis
A blood clot in the deep veins of the leg. Prompt diagnosis prevents clots travelling to the lungs and protects the leg long-term.
Vascular access
Dialysis Access
Creating and maintaining the fistulas and grafts that make haemodialysis possible — a lifeline that deserves specialist care.
General surgery
General & Emergency Surgery
Hernias, gallstones, appendicitis, skin lumps, abdominal pain and gastrointestinal bleeding — managed with the same minimally invasive philosophy, with endoscopy in-house.
Arterial disease
Peripheral Arterial Disease
Narrowed leg arteries causing cramping on walking, rest pain or non-healing wounds. Early treatment protects the limb.
