Vascular surgery has evolved over the past two decades. The specialty has increasingly separated from general surgery as evidence accrues that outcome for patents are better when arterial operations are done by a specialist.[1]Due to the recent recognition of the multisystem nature of vascular disease,vascular surgery has been working in collaboration with the multidisciplinary teams of various specialties.Surgical decisions are now often made more efficiently with input from the renal physician, diabetologist, radiologist, cardiologist and specialist nurse.
Various developments have been made, both at arterial and vein treatment level.
In the venous side , various new developments have been made like endovenous approaches and foam sclerotherapy …show more content…
Endovascular interventions have come as a big boom to the field of vascular surgery.Commonly used endovascular procedures are angioplasty and stenting .Angioplasty uses a medical "balloon" to widen blocked arteries. The balloon presses against the inside wall of the artery to open the space and improve blood flow. A metal stent is often placed across the artery wall to keep the artery from narrowing again.To treat a blockage in the leg, angioplasty can be done in almost all major peripheral vessels from aorta to popliteal artery .New developments in the field of endovascular is the development of Cutting balloon angioplasty , Cryoplasty , Stent grafting , Excisional atherectomy and laser assisted angioplasties . Angiogenesis , drug eluting and biodegradable stents are new developments in the endovascular field of vascular surgery . Endovascular repair of abdominal aortic aneurysm ( EVAR )was introduced a decade ago. This operation involves radiographically guided intraluminal placement of a prosthetic graft on a wire mesh into the abdominal aorta. This is done via a small groin incision thus avoiding the morbidity and mortality associated with major open abdominal surgery. As with conventional repair the goal of endovascular treatment is to prevent further expression by excluding flow within the aneurysm thus reducing the risk of rupture. As this method involves less pre-operative blood loss and fewer cardiovascular complications, the recovery period is shorter. The procedure can be done under local anesthesia.Early Results of EVAR have shown early safety and efficacy is well established in the form of lower mortality and major morbidity. Other benefits like - less blood loss-shorter length of stay-quicker recovery are also there but results are awaited for long term durability and outcomes in patients treated with EVAR . Exciting advances have been made in the repair of the
