..The device is a modular bifurcated system with nitinol/expanded polytetrafluoroethylene components and a smaller profile than currently approved devices...

..The purpose of this report is to describe an interesting cause of endoleak and detail-specific techniques for identifying small transgraft defects, which we have termed microleaks...

..This trial evaluated the safety and effectiveness of thoracic endovascular aortic repair (TEVAR) with a contemporary endograft system compared with open surgical repair (open) of descending thoracic aortic aneurysms and large ulcers...

..Better selection of patients for any method of repair may improve overall utility more than choice of open or endovascular techniques...

..This report describes the particular characteristics of a next generation modular endograft and the Phase I results in 29 patients. Larger comparative studies are in progress to assess the safety and efficacy of this new design...

..As elective repair with modern reoperative techniques can be safely performed, routine computed tomographic examination is advisable at least every 5 years after aortic operations...

....

..To report a technique for the insertion of an inferior vena cava (IVC) filter under intravascular ultrasound (IVUS) guidance...

..In today's cost-conscious world, the viability of this new technology may be dependent on balancing the short-term benefits of this procedure against its associated requirements for monitoring and subsequent reinterventions...

..The purpose of this study was to report a feasibility trial approved by the Institutional Review Board for insertion of inferior vena cava (IVC) filters with intravascular ultrasound (IVUS) guidance in the intensive care unit...

..Therefore, this study is designed to determine the effect of PT on aneurysm size following endovascular grafting...

..These are not efficient for gene delivery. A cationic formulation that allows directed gene delivery while retaining acoustic properties may provide more efficient transfection...

..The purpose of this study was to determine the necessity of bilateral lower-extremity venous duplex ultrasound scanning in patients with unilateral symptoms of deep vein thrombosis (DVT)...

..Focal ectasia of the midpopliteal artery was common. Planning for endovascular treatment of popliteal aneurysms must incorporate this striking enlargement...

..Using ultrasound surveillance, these can be followed up at 3- to 12-month intervals, depending on their size, with operative intervention reserved for aneurysms that enlarge rapidly, become symptomatic, or reach 5.5 cm in diameter...

..Endovascular AAA repair did not acutely alter these anatomic findings. Patients with AAA may therefore be at lower risk of developing LCIV thrombosis owing to the nature of their anatomy...

..Long-term durability of endovascular repair of traumatic thoracic transections remains unknown, but early and midterm results are promising...

..Endovascular management of both acute and chronic thoracic aortic pathology has emerged as an alternative to open surgery. We reviewed our single center experience with endovascular devices for the treatment of thoracic aortic pathology...

....

..Long-term efficacy regarding the prevention of sac enlargement remains unclear, and further follow-up is suggested...

....

..Reported are our 30-day and midterm outcomes of CAS...

..Percutaneous endovascular repair of ruptured abdominal aortic aneurysms (RAAAs) has better outcomes than traditional open surgical repair...

....

..The use of specially designed devices appears to be technically feasible and durable, with acceptable morbidity and mortality rates...

..The outcome of postendograft aneurysm rupture is similar to that of rupture without prior endograft therapy...

..Although there have been no adverse clinical events in this group, continued close follow-up is mandatory following endovascular aneurysm repair...

..Whether outcomes after CAS are comparable to those after CEA in the larger population of patients with asymptomatic disease is unclear...

..This may be analogous to type II endoleak or endotension noted after aortic endovascular repair. We recommend PAA excision or endoaneurysmorrhaphy when feasible...

..Until long-term outcome of endoluminal repair is better defined and results of randomized trials available, the choice between endovascular and open repair will continue to rely heavily on patient preference...

..This study was undertaken to compare 1-year and 5-year results of endovascular repair of abdominal aortic aneurysm (AAA) with the Guidant/EVT bifurcated graft system with results of open repair...

..The Excluder endograft is a safe and effective treatment compared with open surgical repair for infrarenal abdominal aortic aneurysms with appropriate anatomy...

..Radiographic evaluation is more sensitive than clinical observation for detection of ventral hernias. Clinical events and reinterventions related to these radiographic abnormalities are rare...

..To evaluate a single center's experience with carotid artery stenting (CAS) and carotid endarterectomy (CEA) performed by vascular surgeons in an entirely veteran population...

..The results of a multicenter trial comparing a bifurcated endograft (AB) with standard open repair (OR) were reviewed to assess the late findings of both methods of AAA treatment...

....

..Early outcomes and restenosis rates in these patients were analyzed and compared with those in de novo lesions...

..The present report explores the use of conduits during EVAR and TEVAR by discussing the current literature, and the authors also describe a preferred method to address unfavorable iliac anatomy through the use of endoconduits...

..Each of the examples reflects the leadership of Dr. James S.T. Yao as well as the participation of other members of the division that have contributed to the progressive advancement of care for patients with vascular disease...

..Compare long-term results of endovascular treatment and standard open repair of abdominal aortic aneurysms in a multicenter, concurrent-controlled trial...

..Switching to a distal balloon occlusion system, which is well tolerated, may be preferred to unprotected predilation. Practitioners of CAS should be versed in both...

..Continued surveillance of aortic neck morphology after descending thoracic aneurysm endografting is recommended...

..The new generation of optional filters may offer clinicians a new option of temporal risk reduction without the long-term complications that can be associated with permanent IVC filters...

..A comparison of Excluder endograft deployment with femoral artery cutdown (FAC) versus percutaneous femoral access (PFA) for treatment of infrarenal AAA was undertaken...
