Vascular surgery is a surgical subspecialty in which diseases of the vascular system, or arteries, veins and lymphatic circulation, are managed by medical therapy, minimally-invasive catheter procedures, and surgical reconstruction. The specialty evolved from general and cardiac surgery as well as minimally invasive techniques pioneered by interventional radiology. The vascular surgeon is trained in the diagnosis and management of diseases affecting all parts of the vascular system except those of the heart and brain. Cardiothoracic surgeons and interventional cardiologists manage diseases of the heart vessels. Neurosurgeons and interventional neuroradiologists surgically manage diseases of the vessels in the brain (e.g., intracranial aneurysms).
Early leaders of the field included Russian surgeon Nikolai Korotkov, noted for developing early surgical techniques, American interventional radiologist Charles Theodore Dotter who is credited with inventing minimally invasive angioplasty, and Australian Robert Paton, who helped the field achieve recognition as a specialty. Edwin Wylie of San Francisco was one of the early American pioneers who developed and fostered advanced training in vascular surgery and pushed for its recognition as a specialty in the United States in the 1970s.
The specialty continues to be based on operative arterial and venous surgery but since the early 1990s has evolved greatly. There is now considerable emphasis on minimally invasive alternatives to surgery. The field was originally pioneered by interventional radiologists, chiefly Dr. Charles Dotter, who invented angioplasty. Further development of the field has occurred via joint efforts between interventional radiology, vascular surgery, and interventional cardiology. This area of vascular surgery is called Endovascular Surgery or Interventional Vascular Radiology, a term that some in the specialty append to their primary qualification as Vascular Surgeon. Endovascular and endovenous procedures can now form the bulk of a vascular surgeon's practice.
The development of endovascular surgery has been accompanied by a gradual separation of vascular surgery from its origin in general surgery. Most vascular surgeons would now confine their practice to vascular surgery and similarly general surgeons would not be trained or practice the larger vascular surgery operations or most endovascular procedures. More recently, professional vascular surgery societies and their training program have formally separated "Vascular Surgery" into a separate specialty with its own training program, meetings, accreditation. Notable societies are Society of Vascular Surgery (SVS), USA; Australia and New Zealand Society of Vascular Surgeons (ANZ SVS). Local societies also exist e.g. New South Wales Vascular and Melbourne Society of Vascular Surgeons (MVSA). Larger societies of surgery actively separate and encourage specialty surgical societies under their umbrella e.g. Royal Australasian College of Surgeons (RACS).
SIR (Society of Interventional Radiology) remains intimately involved with the practice of endovascular therapy. Many of its members form part of a multi-disciplinary team treating vascular disorders alongside vascular surgeons. Although in many parts of the world vascular surgeons have evolved to now work alone.
Arterial and venous disease treatment by angiography, stenting, and non-operative varicose vein treatment sclerotherapy, endovenous laser treatment are rapidly replacing major surgery in many first world countries. These newer procedures provide reasonable outcomes that are comparable to surgery with the advantage of short hospital stay (day or overnight for most cases) with lower morbidity and mortality rates. Historically performed by interventional radiologists, vascular surgeons have become increasingly proficient with endovascular methods. The durability of endovascular arterial procedures is generally good especially when viewed in the context of their common clinical usage i.e. arterial disease occurring in elderly patients and usually associated with concurrent significant patient comorbidities especially ischemic heart disease. The cost savings from shorter hospital stays and less morbidity are considerable but are somewhat balanced by the high cost of imaging equipment, construction and staffing of dedicated procedural suites, and of the implant devices themselves. The benefits for younger patients and in venous disease are less persuasive but there are strong trends towards nonoperative treatment options driven by patient preference, health insurance company costs, trial demonstrating comparable efficacy at least in the medium term.
A recent trend in the United States is the stand-alone day angiography facility associated with a private vascular surgery clinic, thus allowing treatment of most arterial endovascular cases conveniently and possibly with lesser overall community cost. Similar non-hospital treatment facilities for non-operative vein treatment have existed for some years and are now widespread in many countries.
Vascular surgery encompasses surgery of the aorta, carotid arteries, and lower extremities, including the iliac, femoral, and tibial arteries. Vascular surgery also involves surgery of veins, for conditions such as May–Thurner syndrome and for varicose veins. In some regions, vascular surgery also includes dialysis access surgery and transplant surgery.
The main disease categories and procedures associated with them are listed below.

Previously considered a field within general surgery, it is now considered a specialty in its own right. As a result, there are two pathways for training in the United States. Traditionally, a five-year general surgery residency is followed by a 1-2 year (typically 2 years) vascular surgery fellowship. An alternative path is to perform a five or six year vascular surgery residency.
Programs of training are slightly different depending on the region of the world one is in.
|Country||Standards body||Professional representation||Minimum Length of training (post intern)|
|Australia and New Zealand||Royal Australasian College of Surgeons||Australian & New Zealand Society of Vascular Surgery (ANZSVS)||6 years|
|United Kingdom||Royal College of Surgeons of England, Royal College of Surgeons of Edinburgh||Vascular Society of Great Britain and Ireland [www.vascularsociety.org.uk]||8 years|
|United States||American Board of Surgery, American Osteopathic Board of Surgery||Society for Vascular Surgery||5 years ( 4 via 5-year integrated Vascular Surgery Residency)|
