When you need surgery or specialist medical care, knowing which type of doctor to see can sometimes feel confusing. The titles may sound similar, and there can be some overlap between different surgical disciplines, but each specialist brings a particular area of expertise to patient care.
One common question is: What is the difference between a general surgeon and a vascular specialist?
In simple terms, general surgeons are trained to manage a broad range of surgical conditions, while vascular specialists focus specifically on diseases and problems affecting the vascular system, primarily the arteries and veins that carry blood around the body.
In South Africa, vascular surgery is recognised as a surgical subspecialty, with a dedicated Certificate in Vascular Surgery through the Colleges of Medicine of South Africa.
At Legae Vascular, this distinction is particularly relevant. Dr Legae Mogase first completed general surgical training before undertaking further specialist training in vascular surgery, giving our practice expertise in both the broader principles of surgery and the highly specialised management of vascular disease.
Let’s look more closely at what each type of surgeon does, where their areas of expertise differ, and when seeing a vascular specialist may be the appropriate next step.
What Does a General Surgeon Do?
Despite the name, a general surgeon does far more than perform “general” operations.
General surgery is a broad surgical discipline. General surgeons are trained to assess and treat a wide variety of conditions that may require surgical intervention. Their scope can include the abdomen and digestive tract, breast, skin and soft tissue, endocrine conditions, trauma, and other areas of surgical care.
The South African surgical training framework reflects this broad scope, with general surgical training providing exposure to multiple areas of surgery, including vascular surgery. Vascular surgery, however, is also recognised as a separate subspecialty for doctors who undertake further focused training.
Depending on the condition, hospital, resources available, and surgeon’s individual training and experience, a general surgeon may therefore manage certain vascular problems. For complex vascular disease, however, a patient may be referred to a doctor whose work is specifically focused on the vascular system.
It is not a case of one type of surgeon being “better” than another. They simply have different areas of focus.
Think of general surgery as covering a wide surgical landscape, while vascular surgery zooms in on one particularly complex network within the body: the circulation.
What Are Vascular Specialists?
Vascular specialists are doctors with advanced expertise in diagnosing, monitoring, and treating diseases affecting blood vessels.
Your vascular system includes arteries, which carry blood away from the heart, and veins, which return blood towards the heart. Problems within these vessels can affect almost any part of the body and may range from troublesome varicose veins to serious arterial blockages or aneurysms.
Importantly, seeing a vascular specialist does not automatically mean that you need an operation.
Modern vascular care includes medical management, surveillance, lifestyle and risk-factor management, minimally invasive endovascular treatment, and traditional open surgery. The appropriate approach depends on the condition, its severity, the patient’s anatomy, overall health, and other individual factors.
Legae Vascular provides evidence-based vascular care using both endovascular and open surgical techniques when appropriate.
Vascular Specialist vs General Surgeon: What Is the Main Difference?
The biggest difference is depth of specialisation within the vascular system.
A general surgeon is trained across multiple surgical areas. A vascular surgeon builds on surgical training with additional specialised education and practical experience focused on vascular disease.
This means vascular specialists spend their working lives dealing with conditions involving circulation and blood vessels.
Their work may include assessing why blood flow to a leg has become restricted, treating abnormal veins, creating reliable access for dialysis, repairing aneurysms, managing vascular injuries, or restoring circulation when an artery becomes significantly narrowed or blocked.
For patients with complicated vascular disease, this concentrated expertise can be particularly important because treatment is not always a straightforward choice between “operate” and “do not operate”.
Modern vascular care often requires choosing between several options and determining which offers the most appropriate balance of benefits and risks for the individual patient.
Conditions Vascular Specialists Commonly Treat
There are many reasons why someone may be referred to a vascular specialist.
Our scope of care includes arterial and venous conditions, vascular trauma, aneurysms and dissections, deep vein thrombosis, and dialysis access surgery. We also manage conditions including peripheral artery disease, carotid artery stenosis, vascular complications associated with diabetes, chronic venous insufficiency, and limb-threatening ischaemia.
Peripheral Artery Disease and Arterial Insufficiency
Peripheral artery disease (PAD) occurs when arteries supplying areas such as the legs become narrowed or blocked, reducing blood flow.
Some patients experience discomfort or cramping in the legs when walking. More advanced disease can contribute to persistent symptoms, poor wound healing, or other complications.
A vascular assessment can help determine how severely circulation has been affected and whether management should involve monitoring, medical treatment, risk-factor modification, an endovascular procedure, or surgery.
Varicose Veins and Chronic Venous Insufficiency
Varicose veins are sometimes dismissed as purely cosmetic, but abnormal vein function can also be associated with aching, swelling, skin changes, and, in more advanced cases, venous ulcers.
Chronic venous insufficiency develops when veins have difficulty returning blood efficiently from the legs.
Our treatment options for venous insufficiency can include minimally invasive techniques such as radiofrequency ablation and laser therapy, as well as surgical vein treatment where clinically appropriate.
Deep Vein Thrombosis
Deep vein thrombosis, commonly known as DVT, occurs when a blood clot forms within a deep vein, most frequently in a leg.
Because DVT can cause serious complications, suspected cases require appropriate medical assessment rather than self-diagnosis or simply waiting for symptoms to disappear.
Vascular specialists may form part of the team assessing and managing DVT, its underlying causes, and complications associated with venous circulation.
Aneurysms and Arterial Dissections
An aneurysm occurs when an area of an artery becomes weakened and enlarges. An arterial dissection involves a problem affecting layers of the arterial wall.
These are complex vascular conditions for which specialist assessment can be essential.
Our scope includes thoracic, abdominal, and peripheral aneurysms and dissections. Treatment may involve careful monitoring, open surgical repair, or advanced endovascular techniques, depending on the individual condition.
Carotid Artery Disease
The carotid arteries are major blood vessels supplying the brain. Narrowing of these vessels can be associated with an increased risk of stroke.
A vascular specialist can assess carotid disease and determine whether ongoing medical management, surveillance, or an intervention such as carotid surgery may be appropriate.
Dialysis Access
People undergoing haemodialysis require dependable access to their bloodstream.
Creating and maintaining this access is another important area of vascular surgery. Options may include an arteriovenous (AV) fistula or graft, with the approach selected according to the patient’s anatomy, medical circumstances, and dialysis requirements.
Legae Vascular provides dialysis access creation and management as part of our specialist vascular services.
Vascular Trauma
Accidents and injuries can damage arteries or veins, sometimes requiring urgent specialist management.
Vascular trauma is another area in which the focused expertise of a vascular surgeon may be needed, particularly where circulation to a limb or another part of the body has been compromised.
Vascular Specialists Do More Than Surgery
This is perhaps the biggest misconception surrounding vascular surgery.
Being referred to a surgeon does not necessarily mean you will have surgery.
One of the most important roles of a vascular specialist is determining whether an operation is necessary at all.
The first step is generally understanding the problem as accurately as possible. This may involve a clinical examination and vascular diagnostic testing.
Depending on the condition, investigations used in vascular care may include:
- Doppler ultrasound and duplex scanning
- Ankle-brachial index testing
- CT angiography
- MR angiography
- Venography
- Arteriography
Legae Vascular uses vascular diagnostics together with clinical evaluation to develop an individualised management plan.
Once the condition has been assessed, treatment may involve conservative management, medication, minimally invasive intervention, conventional surgery, or a combination of approaches.
What Is Endovascular Surgery?
Endovascular treatment has transformed many areas of vascular medicine.
Rather than reaching a blood vessel through a larger traditional surgical incision, certain endovascular procedures can be performed through blood vessels using specialised catheters, wires, balloons, stents, or grafts.
These approaches are not suitable for every patient or condition. Open vascular surgery remains essential in many circumstances.
That is why specialist assessment matters.
A vascular surgeon trained in both open and endovascular techniques can evaluate the available options rather than approaching every condition with the same treatment.
Legae Vascular’s services encompass both minimally invasive endovascular interventions and open surgical procedures. These include treatments such as angioplasty and stent placement, endovascular aneurysm repair, carotid endarterectomy, bypass surgery, and procedures for venous disease and dialysis access, when clinically indicated.
When Should You See a Vascular Specialist?
Some vascular conditions are discovered during testing for another medical problem. Others produce symptoms that gradually become more noticeable.
A vascular assessment may be considered if you experience concerns such as:
- Persistent leg discomfort during walking
- Leg pain at rest
- Ongoing swelling in one or both legs
- Prominent or uncomfortable varicose veins
- Changes in the colour or condition of the skin on the legs
- Wounds on the feet or legs that are slow to heal
- Known peripheral artery disease
- A history of DVT or other significant blood clots
- A diagnosed aneurysm
- Carotid artery disease
- Circulatory complications associated with diabetes
- A need for dialysis access
- A vascular injury
Risk factors such as smoking, diabetes, hypertension, and high cholesterol can also contribute to vascular disease and may form part of a specialist’s overall assessment.
These symptoms can have many possible causes, so experiencing one does not automatically mean you have vascular disease. Appropriate medical assessment is important for identifying the cause.
Sudden or severe symptoms that may represent a medical emergency should be assessed urgently through the appropriate emergency medical service rather than waiting for a routine consultation.
Why Specialist Vascular Care Matters in South Africa
South Africa faces a substantial burden from chronic health conditions such as diabetes, hypertension, and cardiovascular disease. Circulatory problems can therefore form part of a much wider picture of a patient’s health.
Effective vascular care frequently involves more than one healthcare discipline.
For example, a patient undergoing dialysis may need input from a nephrologist and vascular surgeon. Someone with complex cardiovascular risk factors may require collaboration between vascular specialists, physicians, and cardiologists. Chronic wounds can require vascular assessment alongside specialist wound care and rehabilitation.
This multidisciplinary philosophy is central to the way we work at Legae Vascular.
Our vascular team collaborates with professionals from areas including cardiology, nephrology, internal medicine, neurology, radiology, physiotherapy, occupational therapy, wound care, and psychology, helping us approach vascular disease as part of the patient’s broader health rather than viewing a blood vessel in isolation.
Specialist Training Makes a Difference
Choosing the appropriate specialist becomes particularly important when vascular disease is complex.
Dr Legae Mogase holds an MBBCH from the University of the Witwatersrand, Fellowship of the College of Surgeons of South Africa, a Master of Medicine in Surgery, and a Certificate in Vascular Surgery.
His professional training has included general surgery at Dr George Mukhari Academic Hospital and vascular surgical training at Steve Biko Academic Hospital, followed by the completion of his vascular surgery subspecialty qualification in 2021.
That progression illustrates the relationship between the two disciplines very well.
A vascular surgeon does not sit completely outside general surgery. Instead, vascular surgery builds on a strong surgical foundation and develops highly focused expertise in the diagnosis and treatment of vascular conditions.
Does a General Surgeon Ever Work With a Vascular Surgeon?
Absolutely.
Modern healthcare is collaborative, and patients are often treated by several specialists.
A general surgeon who identifies a complex vascular problem may refer a patient to a vascular surgeon. Likewise, a vascular specialist may work with general surgeons when patients have multiple conditions or require combined expertise.
We value this team-based approach. Our Johannesburg practice works alongside the Vascare Group of Vascular Surgeons, while our Polokwane services include collaboration with experienced general surgeons.
The goal is not to create competition between specialities. It is to make sure that the right expertise is available for the patient’s particular problem.
Choosing the Right Specialist for Your Condition
If you need an appendix removed, gallbladder surgery, hernia repair, or treatment for another general surgical condition, a general surgeon may be the appropriate specialist.
If the central problem involves an artery, vein, circulation to a limb, an aneurysm, vascular access, or another significant blood-vessel condition, referral to a vascular specialist may be appropriate.
When you are unsure, your GP, physician, emergency doctor, or another treating specialist can help determine which referral is most suitable.
The important thing is not to ignore persistent or worsening symptoms.
Early assessment can give your healthcare team more information, help establish the correct diagnosis, and provide an opportunity to discuss the most appropriate management options before a condition becomes more complicated.

FAQs About Vascular Specialists
What do vascular specialists treat?
Vascular specialists diagnose and manage diseases affecting arteries and veins. These can include peripheral artery disease, chronic venous insufficiency, varicose veins, DVT, aneurysms, carotid artery disease, vascular trauma, and circulatory complications associated with other health conditions.
What is the difference between a vascular specialist and a general surgeon?
A general surgeon is trained across a broad range of surgical conditions. A vascular surgeon has additional specialised training focused on diseases of the vascular system and is trained in medical, endovascular, and open surgical approaches to vascular disease. In South Africa, vascular surgery has a dedicated subspecialty certification pathway.
Do vascular specialists only perform surgery?
No. A vascular specialist may recommend monitoring, lifestyle changes, medication, compression therapy, or other conservative measures where appropriate. Minimally invasive endovascular procedures or open surgery may be considered when required.
Do vascular specialists treat varicose veins?
Yes. Varicose veins and chronic venous insufficiency fall within vascular care. Depending on the condition, treatment may include approaches such as laser therapy, radiofrequency ablation, sclerotherapy, or surgical treatment.
Can a vascular specialist help with poor circulation in my legs?
Yes. Reduced blood flow to the legs may be associated with peripheral artery disease or another vascular condition. A specialist can assess your circulation, perform or request appropriate investigations, and recommend treatment based on the cause and severity.
What tests might a vascular specialist perform?
Depending on your symptoms, vascular assessment may involve Doppler or duplex ultrasound, ankle-brachial index testing, CT or MR angiography, venography, arteriography, or other investigations. Not every patient requires every test.
Do I need a referral to see a vascular specialist in South Africa?
Referral requirements can vary depending on your medical scheme, healthcare provider, and individual circumstances. Your GP or another specialist can refer you when they suspect a vascular problem. If you belong to a medical scheme, it is worth confirming its referral and authorisation requirements before your appointment.
