A stent-graft is a tubular structure composed of two parts. The stent is a mesh-like structure made of metal (such as stainless steel). Its function is to provide support to the graft. The latter is composed of a special fabric that is imprevious to blood and lines the stent. The stent-graft is packed in small diameter tubes and expands to its original diameter when released from these tubes. I use stent-grafts to treat aneurysms.

The procedure of treating aortic aneurysms with stent-grafts is known as EVAR. This stands for EndoVascular Aneurysm Repair. I most commonly use EVAR to treat aneurysms of the abdominal aorta, thoracic aorta and popliteal artery. There are still a number of surgeons who perform open surgery for these conditions. In my opinion, open surgery should be reserved only for those patients in whom EVAR is technically not possible. In my practice, more than 90% of patients are suitable for EVAR. In the average UK hospital this figure is 40 to 60%. 

Why do I use EVAR in preference to open surgery for the treatment of Abdominal Aortic Aneurysms? Click here to find out.
