“…Hertzer et al reported much less graft-related complications(0.4%) with 5-year follow-up, although only clinically evident (as opposed to computed tomography scan-detected) events were considered (Hertzer et al, 2002). Conrad et al described a cohort of 540 open non-ruptured AAA repairs (Conrad et al,2007). 152 Of them had follow-up CT scans which revealed 13 graft-related complications identified in 11 patients, including 7 anastomotic pseudoaneurysms (4 proximal and 3 distal).…”

“…Conrad et al performed CT scanning of 152 of 540 open repairs. There were four graft limb occlusions in the bifurcated grafts that were treated with open thrombectomy and revision of the distal (femoral) anastomosis (Conrad et al, 2007). The Dutch Randomized Endovascular Aneurysm Repair (DREAM) trial followed 178 open and 173 EVAR cases and found a total of 3 occlusions after open repair and 12 after EVAR (De Bruin et al, 2011).…”

“…The DREAM trial reported no graft infections in open repair and 2 after EVAR (De Bruin et al, 2010). Conrad followed 540 aortic grafts and described two graft infections which were identified and treated with graft removal (Conrad et al, 2007). Diagnosis is suspected with, fever, elevated serum CRP and leukocyte count and fluid collections around the graft on CT scan, in the absence of other possible causes of fever.…”

“…Although we have achieved significant technological advances since the first generation of aortic stents, recent information from late postoperative follow-up have shown a significant percentage of complications requiring surgical reintervention. The reason for treatment failure, in many cases, is still connected to the endoprosthesis used (type III leakage) [5][6][7] .…”

Objective: to determine the blood flow pattern changes after endovascular treatment of saccular abdominal aortic aneurysm with triple stent. Methods: we conducted a hemodynamic study of seven Landrace and Large White pigs with saccular aneurysms of the infrarenal abdominal aorta artificially produced according to the technique described. The animals were subjected to triple stenting for endovascular aneurysm. We evaluated the pattern of blood flow by duplex scan before and after stent implantation. We used the non-paired Mann-Whitney test for statistical analysis. Results: there was a significant decrease in the average systolic velocity, from 127.4cm/s in the pre-stent period to 69.81cm/s in the post-stent phase. There was also change in the flow pattern from turbulent in the aneurysmal sac to laminate intra-stent. Conclusion: there were changes in the blood flow pattern of saccular abdominal aortic aneurysm after endovascular treatment with triple stent.

P rogressive aneurysmal degeneration after abdominal aortic aneurysm (AAA) repair can be challenging to treat. Multiple comorbidities, previous operations, and the need for suprarenal cross-clamping place this patient population at high risk for reoperation. 1 During a 5-year period, Conrad and co-authors 2 reported a 24% incidence of late aortic aneurysm proximal to the site of repair in 540 patients who had undergone elective open AAA repair.In 2003, Greenberg and colleagues 3 described an endovascular approach in which parallel visceral-artery stent-grafts were inserted and molded to the main body of the endograft after aneurysmal exclusion. Many other groups have adopted this technique, and short-term and intermediate results appear promising. [4][5][6] We recently used this technique with our own novel modifications to exclude a pararenal AAA while maintaining visceral-artery perfusion. Case ReportIn 2009, a 71-year-old man had undergone open repair of an AAA with a bifurcated 16-mm × 8-cm Dacron prosthetic graft (Fig. 1A). Four years later, he presented with proximal progression of his aneurysmal disease. Abdominal computed tomographic angiography (CTA) showed a 5.3-cm pararenal aneurysm involving both renal arteries (Fig. 1B). Because the patient was at high risk for reoperation, he was referred to us for endovascular aneurysm repair (EVAR). Computed tomographic angiography with 3-dimensional reconstruction revealed no infrarenal neck, thus precluding the use of a fenestrated device. The distance from the superior mesenteric artery (SMA) to the lowest renal artery was 10 mm. The distance from the SMA to the celiac artery was 9 mm. This provided a total approximate distance from the celiac artery to the lowest renal artery of 19 mm, and the celiac artery's diameter was 24 mm, so a chimney graft to the SMA and both renal arteries was considered a viable option. The patient's common femoral arteries (CFAs) were of adequate size for total percutaneous access.The procedure was performed in a hybrid angiography suite with a surgical team on standby. The patient was placed in a supine position, both sides of the groin were anesthetized with 2% buffered lidocaine, and moderate sedation was administered. Meticulous percutaneous access was achieved via fluoroscopic guidance of a 21G micropuncture needle. Bilateral femoral angiography was performed with use of a 3F Techniques
