Early experience shows rapid shrinking of abdominal aortic aneurysms after endovascular treatment with Anaconda® device

Background: The Anaconda® prosthesis is a new endovascular device for abdominal aortic aneurysms repair. Aim of the study was to evaluate successful access to the arterial site, safety and efficacy of stent placement and fixation, assessment of endoleaks, patency of the graft due to twists, kinks or obstruction within the first 30 days after the procedure. Secondary objectives were the assessment of clinical success after 6 months due to graft patency and aneurysm exclusion without endoleak as well as the continuing clinical success without showing aneurysm expansion or any graft failure. Patients and methods: Between 2003 and 2006 a total of 14 patients with infrarenal aortic aneurysm (median diameter prior to endovascular treatment: 56.7 mm (range: 50 to 70 mm)) were treated with the Anaconda® endovascular device. 8 of these patients were treated in accordance to a prospective Phase II clinical study protocol (Anaconda ANA 004). 6 more patients received the same endovascular device after CE-certification. Results: Primary and secondary objectives were achieved in 12 of 14 patients after 6 months. In one patient insertion of the graft system was impossible due to kinking and circular calcification of the iliac arteries. Iliac access utilizing an alternative stent graft system (Cook, Zenith) was also unsuccessful. This patient underwent a conversion to open surgery and died. Another patient died 6 months after treatment unrelated to the procedure. A significant reduction of the median aneurysm diameter from 56.7 to 49.0 mm (range: 45 to 54 mm) was achieved after 6 months (p = 0.05). No endoleak was seen in the follow up. Conclusions: Early results show that he Anaconda® endovascular device for aneurysm repair is a safe and effective device for patients with suitable abdominal aortic aneurysms and proper distal access vessels which results in significant aneurysm diameter decrease and a low complication rate after 6 months of follow-up.

Purpose: To investigate the feasibility of regional anesthesia for endovascular repair of abdominal aortic aneurysms (AAAs). Methods: Since February 1995, 21 patients (17 men and 4 women; median age 67 years, range 49 to 80) have been treated with endovascular technique for true infrarenal AAA using Mialhe Stentor bifurcated grafts. A single dose of spinal anesthesia combined with epidural anesthesia was used in all procedures. Electrocardiography and arterial blood pressure were monitored. Results: No cases of emboli, hematoma, or graft migration were seen, and there were no reoperations or conversions to open operation. Arterial blood pressure was stable at a satisfactory level from induction of anesthesia throughout the procedure, and there was no period of clinically significant hypotension during any implantation. One patient died on the second postoperative day from cardiac and renal insufficiency. Three endoleaks were observed during the procedure; one healed spontaneously within 5 weeks, and the other two were repaired by endovascular techniques after 1 and 4 months, respectively. During follow-up, one patient died at 6 months from pancreatic carcinoma. Conclusions: The application of regional anesthesia is feasible for endovascular treatment of AAA. The arterial blood pressure remained stable throughout the procedure, and all patients, with two exceptions, were mobilized on the first day and placed on a regular diet. Based on these early results, it appears that regional anesthesia is feasible, effective, and safe for endovascular AAA repair.

Risk Of Rupture

Abdominal aortic aneurysm (AAA) is a potentially fatal condition with risk of rupture increasing as maximum AAA diameter increases. It is agreed upon that open surgical or endovascular treatment is indicated if maximum AAA diameter exceeds 5 to 5.5cm. Continuing aneurysmal degeneration of aortoiliac arteries accounts for significant morbidity, especially in patients undergoing endovascular AAA repair. Purpose of this review is to give an overview of the current evidence of medical treatment of AAA and describe prospects of potential pharmacological approaches towards prevention of aneurysmal degeneration of small AAAs and to highlight possible adjunctive medical treatment approaches after open surgical or endovascular AAA therapy.

First Results

SummaryThe endovascular treatment of abdominal aortic aneurysms has generated a great deal of interest since the early 1990s, and many different devices are currently available. The procedure of endovascular repair has been evaluated in many institutions and the different devices are compared. The first results were encouraging, but complications like endoleak, dislocation or thrombosis of the graft occurred. By the available devices the stent application is only promising, if the known exclusion criteria are strictly respected. Therefore a careful preinterventional assessment of the patient by different imaging modalities is necessary. As the available results up to now are preliminary and the durability of the devices has to be controlled, multicenter studies are required to improve the devices and observe their long- term success in the exclusion of abdominal aortic aneurysms.
