using the multilayer stent as a supplement to evar in combined abdominal aortic Aneurysm and iliac artery Aneurysm with inadequate distal landing zone a case report
Vascular and Endovascular Surgery, 2012Co-Authors: Claus Christian Pieper, Carsten H Meyer, Frauke Verrel, Hans H Schild, K. WilhelmAbstract:Combined abdominal aortic Aneurysm (AAA) and iliac artery Aneurysm (IAA) is a common condition. The recently approved Cardiatis Multilayer stent (Cardiatis, Isnes, Belgium) is an innovative stent system for Peripheral Aneurysm management that has been applied in several clinical cases. After deployment, the unique stent design reduces mean velocity and vorticity within the Aneurysm sac, causing thrombus formation and thus exclusion of the Aneurysm while the vessels branching from the Aneurysm remain patent. We describe a case of combined AAA and IAA with successful endovascular Aneurysm repair of the AAA and treatment of the internal iliac artery with the Cardiatis Multilayer stent at 12 months of follow-up.

endovascular management of complex renal artery Aneurysms using the multilayer stent
CardioVascular and Interventional Radiology, 2011Co-Authors: Carsten H Meyer, Frauke Verrel, Gunther Weyer, K. WilhelmAbstract:Since its approval as an innovative stent system for Peripheral Aneurysm management in May 2009, the Cardiatis Multilayer Stent (Cardiatis, Isnes, Belgium) has been applied in several clinical cases. The unique design of this multilayer stent decreases mean velocity and vorticity within the Aneurysm sac immediate and causes thrombus to form, resulting in physiological exclusion of the Aneurysm from the circulation, whereas branches and collaterals sprouting from the Aneurysm remain patent. Here we present a case of a complex renal artery Aneurysm successfully treated with a 6 × 30-mm Cardiatis Multilayer Stent.

risk of new Aneurysms after surgery for popliteal artery Aneurysm
British Journal of Surgery, 2008Co-Authors: Hans Ravn, Anders Wanhainen, Martin BjorckAbstract:Even if popliteal artery Aneurysm (PAA) is the most common Peripheral Aneurysm, no single surgeon or institution has enough patients to study this disease with appropriate scientific methods, and no population-based investigation exists. PAA epidemiology, treatment, management, and outcome were studied in a population-based study of 571 patients (717 legs) primarily operated on for PAAs and 100 episodes of preoperative thrombolysis in Sweden between 1987 and 2002. Patients were identified in the Swedish Vascular Registry and case-records were reviewed. Information on amputation and survival was obtained for all patients, and 190 patients were re-examined with ultrasound, after mean 7.2 years (range 2-18)Median age was 71 years; 5.8% were women. Patients with unilateral PAA had AAA in 28%, increasing to 38% when PAAs were bilateral. Crude survival was 91.4% at one and 70% at five years, significantly lower than among age and sex matched controls. The cumulative incidence for operation of PAA in Sweden was estimated to 8.3/million person year. One-year amputation-rate was 8.8 %, increasing to 11% after follow-up (7.2 years). Independent risk factors for amputation within one year were poor run-off, age, emergency procedure, and prosthetic graft. Run-off was improved by preoperative thrombolysis among 87% of legs, when acute ischemia. After surgical repair with a medial approach the risk of late expansion of the Aneurysm was 33%, with a posterior approach 8% , p=0.014. Among 190 re-examined patients, 108 (57%) had at least one additional Aneurysm at index-operation, increasing to 131 (68%) at re-examination, the total number of Aneurysms increasing by 42% (from 244 to 346).Conclusions: Multiple Aneurysms are common among patients operated on for PAA. Preoperative thrombolysis improves run-off and decreases the amputation-rate in PAAs with acute ischemia. Vein grafts do better than prosthetic grafts, especially when a long bypass is needed. Posterior approach, when possible, reduces the risk of late expansion. A complete examination of the aorto-iliac and femoro-popliteal arteries is warranted at the time of surgery. All patients should be kept under life-long surveillance in order to detect and treat newly developed Aneurysms timely. Normal arterial segments should be re-examined after three years.

nationwide study of the outcome of popliteal artery Aneurysms treated surgically

axillary artery cannulation in type a aortic dissection operations
The Journal of Thoracic and Cardiovascular Surgery, 1999Co-Authors: Eugenio Neri, Gianni Capannini, Enrico Carone, Enrico Tucci, F Diciolla, Massimo Massetti, Edvin Prifti, Carlo SassiAbstract:Abstract Background: Femoral arteries are the preferred site of Peripheral cannulation for arterial inflow in type A aortic dissection operations. The presence of aortoiliac Aneurysms, severe Peripheral occlusive disease, atherosclerosis of the femoral vessels, and distal extension of the aortic dissection may preclude their utilization. Axillary artery cannulation may represent a valid alternative in these circumstances. Methods: Between January 15, 1989, and August 20, 1998, in our institution, 22 of 152 operations (14.4%) for acute type A aortic dissection were performed with the use of the axillary artery for the arterial inflow. Axillary artery cannulation was undertaken in the presence of femoral arteries bilaterally compromised by dissection in 12 patients (54.5%), abdominal aorta and Peripheral Aneurysm in 5 patients (22.7%), severe atherosclerosis of both femoral arteries in 3 patients (13.6%), and aortoiliac occlusive disease in 2 patients (9.1%). In all patients, distal anastomosis was performed with an open technique after deep hypothermic circulatory arrest. Retrograde cerebral perfusion was used in 9 patients (40.9%). Results: Axillary artery cannulation was successful in all patients. The left axillary artery was cannulated in 20 patients (90.9%), and the right axillary artery was cannulated in 2 patients (9.1%). Axillary artery cannulation followed an attempt of femoral artery cannulation in 15 patients (68.2%). All patients survived the operation, and no patient had a cerebrovascular accident. No axillary artery thrombosis, no brachial plexus injury, and no intraoperative malperfusion were recorded in this series. Two patients (9.1%) died in the hospital of complications not related to axillary artery cannulation. Conclusions: In patients with type A aortic dissection in whom femoral arteries are acutely or chronically diseased, axillary artery cannulation represents a safe and effective means of providing arterial inflow during cardiopulmonary bypass.
