Ian Loftus: Aneurysms

Aneurysms are abnormal dilatations of arteries that can be serious if they grow large enough to risk bursting, or rupture. The most common area to be affected i the aorta, the main artery in the abdomen. Abdominal aortic aneurysms (AAA) are categorised by their diameter as this predicts the risk of rupture. Aneurysms in excess of 4 cm should be considered for referral. Aneurysms can also affect the arteries in the leg, chest (thoracic aneurysms) or elsewhere in the body. They can usually be recognised by a simple ultrasound scan which can be performed in the clinic.

There is increasing evidence demonstrating that the best results for complex surgery, including abdominal aortic aneurysms, are achieved in units with a high case throughput. Ian works at St George’s Vascular Institute which has one of the largest practices in the UK for the repair of abdominal and thoracic aneurysms, performing over 120 operations per year. Ian runs the Regional Aneurysm Screening at St Georges’, and can provide the full spectrum of advice and treatment including medical, surgical and endovascular intervention.

There are a number of surgical techniques appropriate for the modern treatment of AAA, particularly endovascular aneurysm repair or stenting. Ian has extensive experience in both approaches. St Georges’ now has an international reputation in endovascular procedures. Endovascular repair is a minimally invasive method whereby the affected artery is relined with a covered stent placed under X-ray control. This excludes the aneurysm from the circulation and prevents further expansion. There are a number of significant advantages to endovascular aneurysm repair including a much shorter hospital stay and earlier return to work or an acceptable quality of life. It is also considerably safer than conventional ‘open’ surgery.

If you are diagnosed as having an aneurysm, or are worried about developing one, Ian can discuss all of the options available to you. There are many variations to the type of procedure that might be required and all of the options will be discussed with you fully.
