概述:Significant stent graft remodeling commonly occurs after endovascular repair of thoracic aortic dissections because of continuing expansion of the true lumen.A suboptimal proximal landing zone, minimal oversizing, and lack of a healthy distal attachment site are unique factors affecting long-term stent graft stability. We used computational fluid dynamic techniques to analyze the biomechanical factors associated with stent graft remodeling in these patients.

概述:Background. We evaluated the application of a new combined surgical and endovascular technique for the treatment of thoracic aortic aneurysms and dissections. The technique is used to treat extensive aortic disease by a single-stage procedure. Surgical outcomes and follow- up data are summarized and analyzed.

概述:The concept of [GrenOpen Endothelium Derived Relaxing Factor GrenClose][RedOpenendothelium-derived relaxing factor RedClose](EDRF) implies that nitric oxide (NO) produced by NO synthase (NOS) in the endothelium in response to vasorelaxants such as acetylcholine (ACh) acts on the underlying vascular smooth muscle cells (VSMC) inducing vascular relaxation.The EDRF concept was derived from experiments on denuded blood vessel strips and, in frames of this concept,VSMC were regarded as passive recipi

概述:The large blood vessels are crucial for blood flow distribution in the body but they may be subjected to disease processes like atherosclerosis, and consequences thereof like aneurysm formation, stroke, and myocardial infarction.These diseases are associated to a majority of the mortality of cardiovascular disease, which may be as high as 33% of overall disease related mortality. The function of these blood vessels has successfully been studied in the framework of biology, physics, and imaging.

概述:To describe our experience with endovascular stent-graft repairs in type B aortic dissection focusing on serious secondary complications resulting in immediate or late conversion to open repair. Methods: From November 1997 to May 2007, 28 patients underwent a thoracic endovascular stent-graft procedure for acute symptomatic type B dissection at our institution. Indication for endovascular repair at our department is a complicated course of type B dissection, including thoracic aortic rupture,

概述:Purpose: The purpose of this study was to characterize the heartbeat-related displacement of the thoracic aorta in patients with chronic aortic dissection type B (CADB). Materials and methods: Electrocardiogram-gated computed tomography angiographywas performed during inspiratory breath-hold in 11 patients with CADB: Collimation 16mm×1mm,pitch 0.2, slice thickness 1mm, reconstruction increment 0.8mm. Multiplanar reformations were taken for 20 equidistant time instances through both ascending (AA

概述:Introduction: Aortic arch aneurysm repair continues to pose a formidable technical challenge in a patient population with significant co-morbidity. Report: We present a successful endovascular repair of an 8.4 cm aortic arch aneurysm, in a 74 year old man, who’s previous median sternotomy showed signs of delayed healing, precluding open repair. Discussion: Applied endovascular techniques obviated the need for aortic clamping, cardiac bypass, or hypothermic circulatory arrest, via an approa

概述:Objective: This report summarizes the 30-day and 12-month results of endovascular treatment using the Medtronic Vascular Talent Thoracic Stent Graft System (Medtronic Vascular, Santa Rosa, Calif) for patients with thoracic aortic aneurysms (TAA) who are considered candidates for open surgical repair. Methods: The study was a prospective, nonrandomized, multicenter, pivotal trial conducted at 38 sites. Enrollment occurred between December 2003 and June 2005. Standard follow-u

概述:Isolated acute dissection of the abdominal aorta is an unusual event that may present with several different clinical scenarios. Because its incidence is low, the natural history is unknown. We report data from the International Registry of Acute Aortic Dissection(IRAD), the largest group of patients treated for acute aortic dissections. The aim of this study was to identify clinical characteristics, therapeutic approaches, risk factors for mortality, in-hospital outcome, and long-term results o

概述:Patients with extensive aortic aneurysms involving the ascending aorta, aortic arch, and the descending aorta are still considered to be a challenge for many cardiovascular surgeons.

概述:Advances in endovascular technology have led to the introduction of fenestrated stents to treat juxtarenal aneurysms (JRAs), previously deemed unsuitable for standard endovascular repair (EVR). This article reviews the outcomes of fenestrated technology and makes a comparison with open repair.
