Abstract
BACKGROUND Ascending aortic aneurysm disease (AAAD) shows a low frequency, heterogeneous behavior, high risk of rupture, dissection and mortality, making elective surgery necessary. Several procedures have been developed, and the Bentall technique is considered as the reference standard. The objective was to describe the hospital mortality of AAAD surgically treated using the Bentall procedure. METHODS We carried out a descriptive study. Included were 23 patients with AAAD who were operated on between March 1, 2005 and September 30, 2008 at our hospital. Data were obtained from clinical files, and descriptive statistics were selected for analysis. RESULTS The study population was comprised of 23 patients with an average age of 46 years; 83% were males. Etiology was nonspecific degeneration of the middle layer with valve implication in 43%, bivalve aorta in 22%, Marfan syndrome, Turner's syndrome and poststenotic aneurysms each represented 9%, and Takayasu disease and ankylosing spondylitis 4% each. Associated heart disease was reported in six (26%) patients as follows: aortic coarctation (2), ischemic cardiopathy (1), atrial septal defect (1), severe mitral insufficiency (1) and subaortic membrane (1). Procedures carried out were Bentall surgery in 20 (87%) patients and aortoplasty with valve prosthesis in three (13%) patients. Complications reported were abnormal bleeding with mediastinal exploration (17%), nosocomial pneumonia (13%), arrhythmia (13%), and septic shock (9%). Mortality was reported in three (13%) patients due to septic shock and ventricular fibrillation. CONCLUSIONS Surgical mortality with the Bentall procedure is similar to published results by other specialized centers. Events related to the basic aortic pathology, surgical technique, aortic valve prosthesis and left ventricular dysfunction encourage longterm studies with follow-up.

Abstract
OBJECTIVES Aortoiliac aneurysms comprise up to 43% of the specialist endovascular caseload. In such cases endovascular aneurysm repair (EVAR) requires distal extension of the aortoiliac endograft beyond the ostium of the internal iliac artery (IIA) and into the external iliac artery, conventionally necessitating the embolisation of one or both IIA. This has been associated with a wide range of complications, and the use of an Iliac Branch-graft Device (IBD) offers an appealing endovascular solution. DESIGN Medline, trial registries, conference proceedings and article reference lists were searched to identify case series reporting IBD use. Data were extracted for review. RESULTS Nine series have reported the use of IBD in a total of 196 patients. Technical success was 85-100%. Median operating times were 101-290min and median contrast dose was 58-208g, with no aneurysm-related mortality. Claudication developed in 12/24 patients after IBD occlusion. One type I endoleak and two type III endoleaks occurred and were managed endovascularly. Re-occlusion occurred in 24/196 patients. CONCLUSION IBD was performed with high technical success rates and encouraging mid-term patency. Formalised risk stratification and morphological data are required to identify the group of patients who will benefit most. Cost-effectiveness appraisals are needed for this technique.

Abstract
A 65 year old female patient was admitted with acute onset of severe intermittent claudication in the right lower extremity. Angiography revealed embolic material in the right femoral artery and peripheral arterial thrombosis in the right leg. She was treated with thrombolysis first, thereafter calcified embolic material was removed by open embolectomy. A CT scan showed massive calcification in the thoracic aorta at the level of the occluded left subclavian artery, obviously the origin of embolization. On the second postoperative day she developed critical ischemia in the left lower limb. Angiography showed massive embolization in the left common and external iliac arteries. Following open embolectomy, stentgrafting of the descending thoracic aorta was performed. At one year the patient is in good condition.

Abstract
INTRODUCTION This study aims to evaluate our experience with self-expanding nitinol stent- enabled recanalisation of long-length occlusions (30 cm or more) of the superficial femoral artery (SFA). METHODS 573 patients underwent 842 lower limb interventions from August 2006 to December 2008. A retrospective review of patients undergoing recanalisation of long-length SFA occlusions with self-expanding nitinol stents and an evaluation of their patency and impact on limb salvage, were done. RESULTS 22 patients (mean age 62.5 years, male: female ratio 11:11) underwent 22 long-length SFA stenting procedures. The spectrum of critical limb ischaemia included rest pain (five), ulcer (six) and gangrene (11). Length of occlusions varied from 30 cm to 45 cm (average length 36.4 cm). Five patients had stents placed through the ipsilateral popliteal artery approach, and the rest had stents placed through the femoral artery approach. All patients were followed up over an average duration of 12 months. One patient died due to associated medical conditions during this period. Six out of 21 (28.6 percent) of the stents thrombosed completely on one year follow-up. Of these, two patients underwent amputation, one patient had a bypass, and the stent in two patients were recanalised with balloon angioplasty. All remaining patent stents showed varying degrees of stenoses at one year. The overall limb salvage rate at one year following stent placement was 81 percent. CONCLUSION Our experience showed the beneficial result of long-length SFA stent placement with good limb salvage outcome. Repeat interventions may be required to maintain the patency of stents in these patients.

Abstract
OBJECTIVE The aim of this study was to assess the outcome of 3 different surgical approaches for treatment of acute aortic dissection type A (AADA) with involvement of the aortic root. MATERIALS AND METHODS From November 2002 to December 2007, 51 consecutive patients underwent emergency surgical intervention for AADA with involvement of the aortic root. Supracommissural replacement (SCR) of the ascending aorta was applied to 33 of these patients; 12 cases received a Bentall procedure, and 6 underwent partial remodeling technique in which as much as the dissected aortic root was resected, leaving a rim of 10 mm above the noncoronary annulus and 5 mm above the coronary ostia and commissures. Woven Dacron graft tailored in a scallop-shaped configuration to match the noncoronary sinus was then anastomosed to the proximal aortic stump. RESULTS Overall hospital mortality was 16% and showed no significant differences among groups. SCR showed a trend toward higher aortic root morbidity. Mean operation time, cardiopulmonary bypass time, and cardiac ischemia time were significantly longer for the Bentall procedure. CONCLUSIONS In AADA involving aortic root, a partial remodeling technique may be considered the surgical treatment of choice at our institution in suitable patients.

Abstract
Accurate endoleak classification is essential following fenestrated endovascular aneurysm repair (f-EVAR). Both endoleak type and exact source of endoleak have implications upon the urgency and complexity of future management strategies. Herein we report on a patient with a documented endoleak post-f-EVAR, in which the source of blood flow into the aneurysm sac could not be determined using conventional computed tomographic angiography. Consequently, dynamic volumetric computed tomographic angiography (DV-CTA) was employed, which clearly illustrated the site of origin of the endoleak. DV-CTA enables accurate endoleak characterization following f-EVAR, with excellent conspicuity of the source of blood flow into the aneurysm sac.

Abstract
The use of stent grafts in the treatment of ruptured aortic aneurysm, abdominal (AAA) may reduce mortality associated with this process through its dramatic alteration of the surgical technique employed. Advantages of endovascular repair include the ability to perform the procedure under local anesthesia, decreased physiologic stress of avoiding a laparotomy and avoiding collateral damage during open repair. Criticisms of this technique include additional preoperative time spent obtaining appropriate imaging, the necessity for specialized products and personnel required to perform the procedure, and late complications such as abdominal compartment syndrome. Current data regarding a survival advantage appear favorable but flawed, highlighting the need for prospective randomized trial. Three trials are currently underway with the largest, the IMPROVE trial, the most likely to yield definitive evidence.

Abstract
Endovascular stent implantation was introduced to femoropopliteal procedures almost two decades ago. Initial results with balloon-expandable stainless steel stents and self expanding Elgiloy stents, however, were disappointing. In particular, recurrence rates after long-segment femoropopliteal stenting were rather high, in the range of 60% to 80% at 1 year. After years of stagnation, recent developments in femoropopliteal stent technology have been promising. Self-expanding nitinol stents have been evaluated in several prospective studies. Initial problems with stent fractures seem to be resolved using second-generation devices. The second generation of Nitinol stents have an enhanced flexibility particularly also in axial direction due to a reduction of cell interconnections and a more spiral orientation of the interconnections. However, until now there is no proof of any impact of the stent design on restenosis rate. Otherwise, stenting has been shown to be beneficial compared to balloon angioplasty especially in longer femoropopliteal lesions. The superior fracture resistance of the latest stent generation in combination with the production of long nitinol stents of up to 20 cm in length allow that more difficult and complex lesions can be treated endovascularly. The main unresolved problem with femoropopliteal stenting is the treatment of instent restenosis. Future concepts to further improve long-term patency after femoropopliteal stenting are therefore under investigation, including drug-eluting stents (DES), biodegradable stents, and coated stent-grafts. Stent grafts appear to be a viable option for the treatment of complex superficial femoral artery lesions, with comparable outcomes to prosthetic above-knee femoropopliteal bypass surgery. Concerning DES, we have to wait for the results of the ongoing studies.

Abstract
The stiffness as well as the biodegradation rate of collagen and gelatine products can be modulated by performing a number of crosslinking treatments. In many biomedical applications, an optimal degree of crosslinking seems to exist, depending on the mechanical and/or biosynthesis properties of the host site. The aim of this study was to evaluate the optimal degree of crosslinking of collagen and gelatine films, to be used as sealants for vascular prostheses. Various crosslinking treatments, including exposure to aldehydes, dehydrothemal treatment, carbodiimide crosslinking and combinations of them, were performed on collagen and gelatine films, and the resulting increases in stiffness, degree of crosslinking and denaturation temperature were evaluated. Analogue crosslinking treatments were also performed on sealed prostheses, which were then tested for blood leakage. The experimental results showed that a good blood impermeability of both collagen and gelatine films was obtained for crosslinking density of about 1.2-1.3 x 10(-5) mol/cm(3), which could be yielded by a dehydrothermal crosslinking treatment (DHT). In particular, dehydrothermally treated gelatine-coated prostheses were found to perform better than analogue collagen-coated ones. The presence of glycerol in crosslinked collagen films was found to have plasticizing effects, which are likely to facilitate blood impermeability, and to increase the thermal stability of collagen.

Abstract
The results of the endovascular treatment of external iliac artery lesions in patients with claudication are not well known. In the literature, very often, the studied populations are not homogenous (people with claudication and with acute ischemia) and the external iliac artery is not differentiated from the primary iliac artery. Moreover, systematic stenting is still debated. Our goal was to study the results of systematic stenting for atheromatous lesions of the external iliac artery in a consecutive and homogenous population of patients with claudication. From June 2000 to December 2006, 90 external iliac arteries were treated with systematic stenting for atheromatous lesions in 81 consecutive patients with claudication (74 men and 7 women, aged 62+/-12 years). Lesions were classified according to the Trans-Atlantic Intersociety Consensus (TASC). Endovascular treatment was systematically chosen for TASC A (n=40) and B (n=30) patients and patients at high surgical risk for TASC C (n=18) and D (n=2). One hundred and seven stents were placed; they were 37+/-21 mm long with a 7+/-0.6mm diameter. Clinical examination and duplex follow-up were carried out at a minimum of 3 months and at the end of the follow-up. There was a 2.2% complication rate, without any deaths (retroperitoneal hematoma). Mean follow-up was 23 months (with a 13-month median). Primary patency rate was 97% (standard error [SE] 2%) at 1 year, 90% (SE 4.6%) at 2 years, and 84% (SE 6.6%) at 3 years. Secondary patency rate was 98% (SE 1.5%) at 1 year, 93% (SE 3.9%) at 2 years, and 93% (SE 4.5%) at 3 years. Ten restenoses were detected and treated by endovascular techniques (n=6), bypass (n=2), or medication (n=2). At the end of the follow-up, the patients were asymptomatic (n=62) or presented with a moderate (n=17) or severe (n=8) claudication. A patient with hemodialysis was amputated at the metatarsal level. No significant predictive restenosis factor was discovered. However, the C or D TASC classification seemed to favor an earlier restenosis (p=0.06). In conclusion, our study demonstrates that, in a larger population than in the literature, systematic stenting on the external iliac artery gives satisfying results in patients with claudication.

Abstract
INTRODUCTION Clinical use of the Amplatzer vascular plug in the cardiopulmonary and peripheral vasculatures has been described extensively in the literature. We present our initial experience in adapting this device for therapeutic sacrifice of major craniocerebral arteries. MATERIALS AND METHODS Between July 2007 and November 2008, 8 patients (mean age 59.1 years; range 18 to 82 years) underwent therapeutic occlusion of major craniocerebral arteries using the device, for direct caroticocavernous fistula (1 patient), symptomatic unruptured giant cavernous internal carotid aneurysms (2 patients), and preoperative embolisation before surgical resections of skull base tumours that had encroached upon the internal carotid or vertebral artery (5 patients). The plugs were used alone or in conjunction with detachable platinum coils. The applications of the device, as well as the angiographic and clinical results of the procedures were evaluated. RESULTS Applications of the plugs were straightforward and successful in all cases, with hermetic occlusions of all target arteries. When used without additional coils, several plugs were deployed in tandem to achieve complete occlusion of the artery. No migration of the device was seen. No patient developed untoward neurological deficits following the procedures, and the 3- and/or 6-month follow-up showed stable results. CONCLUSION The Amplatzer vascular plug could be a valuable addition to the neurointerventional armamentarium, particularly in therapeutic occlusion of major craniocerebral arteries. Rigidity of the delivery system limits its current use to vessels below the skull base. The potential risk of distal thromboembolism also requires further evaluation.
