Endovascular repair of abdominal aortic aneurysm is a common procedure and not without complications. The aim of this study was to evaluate the early results of the Anaconda endograft (Vascutek Ltd., Inchinnan, Scotland, UK) in 106 patients in three hospitals in the west of Scotland. A prospective registry of 106 consecutive patients undergoing endoluminal repair of their abdominal aortic aneurysms using the Anaconda device was set up to record the clinical outcomes, with a mean follow-up of two years. There was no 30-day perioperative mortality in the 106 patients. Only type II endoleaks were detected on serial computed tomography scanning at follow-up. Technical success was achieved in 99% (105/106) in this study; one patient was converted to open surgical repair. Two cases of proximal device migration (>1 cm) were detected at one month and 19 months, respectively, with no associated endoleak or sac enlargement. Five cases of endograft limb thrombosis were noted in this study. Our early clinical experience with the Anaconda endograft compares favourably with other commercially available endografts in the treatment of abdominal aortic aneurysms. The main advantages of this device are that it is re-deployable and that it has a magnetic wire system which makes it easy to implant.

The Anaconda is a modular bifurcated stent-graft of woven polyester and nitinol ring stents that has been commercially available since 2005. It was the first truly repositionable stent-graft and features a magnet wire contralateral limb cannulation system. It has excellent fixation and sealing properties and its ring stent construction results in it being highly conformable and therefore applicable in angulated and tortuous anatomy

This study reports the technical and mid-term clinical results of the second-generation Anaconda AAA Stent Graft System endovascular device for treatment of abdominal aortic aneurysm (AAA). The design of the Anaconda AAA Stent Graft System is characterised by a three-piece system consisting of two proximal independent saddle-shaped nitinol self-expandable rings with hooks fixation, zero body support and vacuum-cleaner tube leg design

Fifty-one patients (48 men; mean age 7168 years, range 62?89) were treated with the Anaconda stent-graft from January 2006 to September 2007. Six patients were considered at high risk for open repair (defined as ASA grade 3) and 10 had undergone previous laparotomy. The mean neck diameter and length were 26 mm (range 22?30) and 18.5 mm (range 14?35), respectively. Mean proximal neck angulation was 30(range 5?60). Severe iliac artery tortuosity (60) was seen in 20 (39%) patients; 3 (6%) had a proximal aneurysm neck angle 45.
