Vascular Surgery
Vascular surgery is the surgical and endovascular specialty concerned with diseases of the arteries, veins, and lymphatic vessels outside the heart and brain. It spans aneurysmal, occlusive, and venous disorders, and over recent decades has shifted from predominantly open reconstruction toward minimally invasive catheter-based (endovascular) techniques alongside open repair.
Definition
Vascular surgery is the branch of surgery that diagnoses and treats disorders of blood and lymphatic vessels through open operative reconstruction, endovascular intervention, and medical co-management, excluding the intracranial and coronary circulations that fall to neurosurgery and cardiac surgery.
Scope
This area orients the reader to the vascular system as the object of surgical care and frames the major problem categories addressed within general surgery: arterial aneurysm (exemplified by abdominal aortic aneurysm), acute and chronic arterial occlusion, venous thromboembolic disease, and chronic venous disorders such as varicose veins. It is a reference overview that points to its constituent topics rather than a clinical management manual.
Sub-topics
Key concepts
- Open versus endovascular repair
- Arterial aneurysm and dilatation
- Arterial occlusive disease and ischaemia
- Venous thromboembolism
- Chronic venous disease
- Atherosclerosis as a systemic substrate
- Limb salvage and revascularisation
Mechanisms
The disorders treated in vascular surgery arise from a small set of vessel-wall and flow processes: degeneration and dilatation of the arterial wall producing aneurysm, atherosclerotic narrowing and thrombosis producing occlusion and ischaemia, and venous wall and valve dysfunction producing reflux, dilatation, and stasis that predisposes to thrombosis. Surgical and endovascular approaches address these by excluding, bypassing, recanalising, or removing the affected segment while preserving distal perfusion or venous return.
Clinical relevance
Vascular disease is a major contributor to morbidity and mortality through aneurysm rupture, limb loss, stroke, and venous thromboembolism, so the field intersects broadly with cardiology, radiology, and general medicine. This entry describes the scope of the discipline for educational orientation and does not provide diagnostic thresholds or treatment recommendations for individual patients.
Epidemiology
The burden treated by vascular surgery tracks closely with atherosclerotic and venous disease in ageing populations. Abdominal aortic aneurysm, peripheral arterial disease, and venous thromboembolism are each common, age- and smoking-related, and collectively account for a substantial share of vascular interventions worldwide.
History
Modern vascular surgery emerged in the twentieth century with advances in arterial suturing, prosthetic grafts, and anticoagulation, and was transformed from the 1990s onward by the spread of endovascular techniques such as stent-grafting and angioplasty, which broadened the range of patients who could be treated and reshaped the open-versus-endovascular balance across many conditions.

Frequently asked questions
- What distinguishes vascular surgery from cardiac and neurosurgery?
- Vascular surgery deals with arteries, veins, and lymphatics outside the heart and brain; the coronary circulation is the province of cardiac surgery and the intracranial vessels of neurosurgery, though all three fields overlap with interventional radiology.
- What does 'endovascular' mean?
- Endovascular techniques treat vascular disease from inside the vessel using catheters, balloons, stents, and stent-grafts introduced through small access punctures, in contrast to open surgery that exposes and repairs the vessel directly.
