The vascular team at Frimley Park Hospital has introduced a new stent graft system, known as the Nellix system, for the treatment of abdominal aortic aneurysms (AAA).
This type of aneurysm is a swelling or bulging of the aorta (the largest blood vessel in the body) in the abdomen, and is more common in men over 65 years of age. If an aneurysm gets too big, surgery is required to stop it from rupturing.
The first patient was successfully treated with a Nellix device on 30 June at Frimley Park by a team comprising consultant interventional radiologist Dr Jeremy Taylor, consultant vascular and endovascular surgeons Mr Neville Dastur and Mr Patrick Chong, with input from Mr Paul Hayes from Cambridge University Hospitals NHS Foundation Trust.
Neville Dastur explained: “Minimally invasive techniques such as endovascular aneurysm repair (EVAR) to treat AAA are well established and offer a less traumatic approach to aneurysm repair for suitable patients than open surgery.
“However, standard infra-renal EVAR devices are not suitable for all patients depending upon the exact location of the aneurysm. And a proportion will require further procedures in later years.
“The Nellix device, which has a new concept of sealing and fixation within the aneurysm sac, enables us to treat some aneurysms that previously required more costly, custom made systems. Furthermore, we hope the new system will reduce the need to re-operate on some patients.”
Patrick Chong agreed and added: “We have great surgical outcomes in aortic surgery for our team of vascular surgeons on the National Vascular Registry and this new stent graft adds another useful option to our wide range of treatments against aneurysms available here at Frimley Park Hospital.”
As an accredited regional vascular hub, the vascular service at Frimley Park Hospital benefits from three interventional radiology suites and a dedicated endovascular hybrid operating theatre.
A team of six vascular consultants and two consultant interventional radiologists work on a rota to provide a round-the-clock emergency service at Frimley Park, seven days a week.
The centre at Frimley also provides aneurysm screening as part of the west Surrey and north Hampshire AAA screening programme.
