“…All endoleaks showed favourable aortic anatomy. 20 In the present study, the mortality rate within 30 days of the procedure was 6.2%. A patient died during conversion to an open surgery due to occlusion of the renal arteries provoked by stent body migration during the procedure.…”

Background: Endovascular treatment has revolutionized the therapeutic approach to abdominal aortic aneurysms due to its low morbidity and mortality rates. Despite technological advances, there are still anatomical limitations to the use of stent grafts. This study aimed to evaluate the immediate clinical results in patients with complex abdominal aortic aneurysms treated with a second-generation stent graft. Methods: This was an observational, prospective, non-randomized, single-centre study with a series of patients who underwent endovascular repair of complex infra-renal abdominal aortic aneurysms using a stent graft with a dual-ring stent design (Anaconda TM , Vascutek-Terumo, Inchinnan, Scotland). Clinical and angiographic characteristics, technical and therapeutic success rates, morbidity and mortality, and perioperative reintervention rates were evaluated. Results: Between February 2010 and December 2011, 108 consecutive patients with aortic aneurysms were treated; 16 had complex abdominal aortic aneurysms treated with the Anaconda TM AAA Stent Graft System. The mean age was 76 ± 7 years and 75% were males. Technical success was observed in 94% of the cases and therapeutic success was achieved in 75% of the cases. There was one postoperative death. The most prevalent perioperative complications were surgical wound bleeding (2/16) and peripheral embolism (2/16). Reinterventions were required in 12.5% of the patients during follow-up. Conclusions: In this study, the second-generation Anaconda TM Stent Graft System was effective and provided satisfactory immediate results in the treatment of complex infra-renal abdominal aortic aneurysms.

“…Small numbers aside, mortality from the AUI configuration was 1.6%. 13 Although the secondary endovascular reintervention rates trended higher for the AUI group in our report, and more so compared with open AAA repair, 14 endoleaks were not significantly different between the two cohorts, and the AUI device configuration allowed aneurysm exclusion in patients who otherwise may not have been suitable for EVAR with a BIF device, with similar rates of morbidity and mortality. A longer period of observation would of course be necessary to evaluate these variables further.…”

The AUI configuration extends endovascular aneurysm repair feasibility to several hostile anatomic conditions. Despite increased comorbidities in the recipient patient population and associated higher rates of postoperative myocardial infarction and respiratory complications, early outcomes with the new generation of AUI devices are acceptable and comparable to those after treatment with BIF configurations.

“…The implantation procedure usually takes less time and radiations and the overall cost is substantially reduced [9]. Tubular endografts are also less likely to occlude as they have no kinking or twisting, if compared to bifurcated and aorto-monoiliac devices [10]. In our series, in fact, we did not observe any graft thrombosis.…”

BackgroundWe describe our 8-year experience with the use of endovascular techniques (ET) for the treatment of abdominal aortic aneurysms (AAA) through a straight endograft.MethodsWe retrospectively reviewed data of all patients who were treated for AAA using ET in two centres from 1998 to 2012 and who received a single straight endograft (group A) or a double straight tube (group B). Outcomes were analyzed to assess survival, absence of endoleak and absence of reintervention for both groups. Log-rank and Chi-Square were used as appropriate to make comparison between the two groups. P values < .05 were considered statistically significant.ResultsFifty-three patients from 1998 to May 2012 were treated for AAA using a straight endograft. In 28 cases (52.8%) a single aortic straight tube was used (Group A), while in the remaining cases a “double trombone technique” was used (Group B).Primary success was obtained in 52 cases (98.1%). In one patient of group A immediately after the operation we observed a type Ia endoleak, which was correct with a proximal aortic cuff.Fluoroscopy time, operation time, amount of intraprocedural contrast medium and blood loss were slightly higher for group B, even if not significantly. Mortality at 30 days was nil for both groups. Mean follow-up was 49 months (range 2–153 months).Five patients died in group A, four of them for a neoplastic disease and the remaining for aortic rupture. No patients died in group B. Endoleaks occurred more frequently in patients of group A (5 type I endoleaks and 1 type II endoleak from a lumbar artery).Reintervention were more frequent for patients of group A, being type I endoleak the main cause. A stent fracture was observed in a patient who received EVAR by “trombone technique” 3 months later. Reintervention was then necessary and a third stent was successfully placed to cover the lesion.ConclusionsIn our experience the endovascular repair of AAA using straight aortic endografts was a safe and effective technique. Reintervention and endoleaks were slightly more frequent in patients who had received a single endograft compared to patients who were treated using the “trombone technique”.
