Vascular Surgery involves the specialist care of patients with vascular disease and disorders of the blood vessels and lymphatic system (excluding the brain and heart), including diabetes, blockages in the arteries or veins, blood clots, aneurysms, varicose veins, graft infections, among others. It involves clinical assessment, diagnosis and treatment - both surgical and non-surgical. It is underpinned by internal medicine, but further studies the basic sciences, including anatomy, pathology and physiology, which relate to the vascular system. It studies diagnoses of vascular conditions, including application of diagnostic tools and medical imaging, professionalism and ethics, and preoperative and perioperative assessment and management of patients. Surgical management includes endoluminal techniques, vascular access procedures, interventional procedures, management of trauma, wound healing, and pre, peri and post -operative care. Vascular surgery aims to improve the flow of circulation through the body, reduce vascular disease complications, and improve health. Surgery examples include bypass operations, stenting and angioplasty, minimally invasive catheter procedures and surgical reconstruction. To provide appropriate patient care, Vascular Surgery interacts with other medical and surgical specialties, such as Cardiothoracic Surgery, Cardiology, Diabetes Medicine, Interventional Radiology, Renal Medicine, Stroke Medicine and Transplant Surgery. Vascular surgery includes both acute and elective surgery and is practiced in both emergency and outpatient settings.
