Infrainguinal revascularisation in the era of vein-graft surveillance--do clinical factors influence long-term outcome? (1/3358)

OBJECTIVES: To investigate the variables affecting the long-term outcome of infrainguinal vein bypass grafts that have undergone postoperative surveillance. DESIGN: A retrospective analysis. PATIENTS AND METHODS: Details of 299 consecutive infrainguinal vein grafts performed in 275 patients from a single university hospital were collected and analysed. All grafts underwent postoperative duplex surveillance. Factors affecting patency, limb salvage and survival rates were examined. These factors were gender, diabetes, hypertension, aspirin, warfarin, ischaemic heart disease, run-off, graft type, early thrombectomy, level of anastomoses and indication for surgery. RESULTS: The 6-year primary, primary assisted and secondary patency rates were 23, 47, and 57%, respectively. Six-year limb salvage and patient survival were 68 and 45%, respectively. Primary patency was adversely influenced by the use of composite vein grafts. Early thrombectomy was the only factor that significantly influenced secondary patency. Limb salvage was worse in diabetic limbs, limbs with poor run-off and in grafts that required early thrombectomy. Postoperative survival was better in males, claudicants and in patients who took aspirin. CONCLUSIONS: Although co-morbid factors did not influence graft patency rates, diabetes did adversely effect limb salvage. This study, like others before it, confirms that aspirin significantly reduces long-term mortality in patients undergoing infrainguinal revascularisation.  (+info)

Isolated femoropopliteal bypass graft for limb salvage after failed tibial reconstruction: a viable alternative to amputation. (2/3358)

PURPOSE: Femoropopliteal bypass grafting procedures performed to isolated popliteal arteries after failure of a previous tibial reconstruction were studied. The results were compared with those of a study of primary isolated femoropopliteal bypass grafts (IFPBs). METHODS: IFPBs were only constructed if the uninvolved or patent popliteal segment measured at least 7 cm in length and had at least one major collateral supplying the calf. When IFPB was performed for ischemic lesions, these lesions were usually limited to the digits or small portions of the foot. Forty-seven polytetrafluoroethylene grafts and three autogenous reversed saphenous vein grafts were used. RESULTS: Ankle brachial pressure index (ABI) increased after bypass grafting by a mean of 0.46. Three-year primary life table patency and limb-salvage rates for primary IFPBs were 73% and 86%, respectively. All eight IFPBs performed after failed tibial bypass grafts remained patent for 2 to 44 months, with patients having viable, healed feet. CONCLUSION: In the presence of a suitable popliteal artery and limited tissue necrosis, IFPB can have acceptable patency and limb-salvage rates, even when a polytetrafluoroethylene graft is used. Secondary IFPB can be used to achieve limb salvage after failed tibial bypass grafting.  (+info)

The value of late computed tomographic scanning in identification of vascular abnormalities after abdominal aortic aneurysm repair. (3/3358)

PURPOSE: The purpose of this study was to determine the prevalence of late arterial abnormalities after aortic aneurysm repair and thus to suggest a routine for postoperative radiologic follow-up examination and to establish reference criteria for endovascular repair. METHODS: Computed tomographic (CT) scan follow-up examination was obtained at 8 to 9 years after abdominal aortic aneurysm (AAA) repair on a cohort of patients enrolled in the Canadian Aneurysm Study. The original registry consisted of 680 patients who underwent repair of nonruptured AAA. When the request for CT scan follow-up examination was sent in 1994, 251 patients were alive and potentially available for CT scan follow-up examination and 94 patients agreed to undergo abdominal and thoracic CT scanning procedures. Each scan was interpreted independently by two vascular radiologists. RESULTS: For analysis, the aorta was divided into five defined segments and an aneurysm was defined as a more than 50% enlargement from the expected normal value as defined in the reporting standards for aneurysms. With this strict definition, 64.9% of patients had aneurysmal dilatation and the abnormality was considered as a possible indication for surgical repair in 13.8%. Of the 39 patients who underwent initial repair with a tube graft, 12 (30.8%) were found to have an iliac aneurysm and six of these aneurysms (15.4%) were of possible surgical significance. Graft dilatation was observed from the time of operation (median graft size of 18 mm) to a median size of 22 mm as measured by means of CT scanning at follow-up examination. Fluid or thrombus was seen around the graft in 28% of the cases, and bowel was believed to be intimately associated with the graft in 7%. CONCLUSION: Late follow-up CT scans after AAA repair often show vascular abnormalities. Most of these abnormalities are not clinically significant, but, in 13.8% of patients, the thoracic or abdominal aortic segment was aneurysmal and, in 15.4% of patients who underwent tube graft placement, one of the iliac arteries was significantly abnormal to warrant consideration for surgical repair. On the basis of these findings, a routine CT follow-up examination after 5 years is recommended. This study provides a population-based study for comparison with the results of endovascular repair.  (+info)

Right atrial bypass grafting for central venous obstruction associated with dialysis access: another treatment option. (4/3358)

PURPOSE: Central venous obstruction is a common problem in patients with chronic renal failure who undergo maintenance hemodialysis. We studied the use of right atrial bypass grafting in nine cases of central venous obstruction associated with upper extremity venous hypertension. To better understand the options for managing this condition, we discuss the roles of surgery and percutaneous transluminal angioplasty with stent placement. METHODS: All patients had previously undergone placement of bilateral temporary subclavian vein dialysis catheters. Severe arm swelling, graft thrombosis, or graft malfunction developed because of central venous stenosis or obstruction in the absence of alternative access sites. A large-diameter (10 to 16 mm) externally reinforced polytetrafluoroethylene (GoreTex) graft was used to bypass the obstructed vein and was anastomosed to the right atrial appendage. This technique was used to bypass six lesions in the subclavian vein, two lesions at the innominate vein/superior vena caval junction, and one lesion in the distal axillary vein. RESULTS: All patients except one had significant resolution of symptoms without operative mortality. Bypass grafts remained patent, allowing the arteriovenous grafts to provide functional access for 1.5 to 52 months (mean, 15.4 months) after surgery. CONCLUSION: Because no mortality directly resulted from the procedure and the morbidity rate was acceptable, this bypass grafting technique was adequate in maintaining the dialysis access needed by these patients. Because of the magnitude of the procedure, we recommend it only for the occasional patient in whom all other access sites are exhausted and in whom percutaneous dilation and/or stenting has failed.  (+info)

Endovascular repair of a descending thoracic aortic aneurysm: a tip for systemic pressure reduction. (5/3358)

A proposed technique for systemic pressure reduction during deployment of a stent graft was studied. A 67-year-old man, who had a descending thoracic aneurysm, was successfully treated with an endovascular procedure. An occluding balloon was introduced into the inferior vena cava (IVC) through the femoral vein. The balloon volume was manipulated with carbon dioxide gas to reduce the venous return, resulting in a transient and well-controlled hypotension. This IVC-occluding technique for systemic pressure reduction may be safe and convenient to minimize distal migration of stent grafts.  (+info)

Infrarenal endoluminal bifurcated stent graft infected with Listeria monocytogenes. (6/3358)

Prosthetic graft infection as a result of Listeria monocytogenes is an extremely rare event that recently occurred in a 77-year-old man who underwent endoluminal stent grafting for infrarenal abdominal aortic aneurysm. The infected aortic endoluminal prosthesis was removed by means of en bloc resection of the aneurysm and contained endograft with in situ aortoiliac reconstruction. At the 10-month follow-up examination, the patient was well and had no signs of infection.  (+info)

Endovascular stent graft repair of aortopulmonary fistula. (7/3358)

Two patients who had aortopulmonary fistula of postoperative origin with hemoptysis underwent successful repair by means of an endovascular stent graft procedure. One patient had undergone repeated thoracotomies two times, and the other one time to repair anastomotic aneurysms of the descending aorta after surgery for Takayasu's arteritis. A self-expanding stainless steel stent covered with a Dacron graft was inserted into the lesion through the external iliac or femoral artery. The patients recovered well, with no signs of infection or recurrent hemoptysis 8 months after the procedure. Endovascular stent grafting may be a therapeutic option for treating patients with aortopulmonary fistula.  (+info)

Intraoperative transoesophageal echocardiography as an adjuvant to fluoroscopy during endovascular thoracic aortic repair. (8/3358)

OBJECTIVES: To define the utility of intraoperative transeophageal echocardiography (TEE) during endovascular thoracic aortic repair. DESIGN: Retrospective study. MATERIALS: Five patients underwent six transluminal endovascular stent-graft procedures for repair of thoracic aortic disease. METHODS: After induction of anaesthesia, a multiplane or biplane TEE probe was placed to obtain views of the diseased aorta. Both transverse and longitudinal planes of the aortic arch and descending thoracic aortic segments were imaged. The aortic pathology was confirmed by TEE and the proximal and distal extents of the intrathoracic lesion were defined. Doppler and colour-flow imaging was used to identify flow patterns through the aorta before and after stent-graft deployment. RESULTS: Visualisation and confirmation of the aortic pathology by ultrasonography was accomplished in all patients. TEE was able to confirm proper placement of the endograft relative to the aortic lesion after deployment and was able to confirm exclusion of blood flow into the aneurysm sacs. CONCLUSIONS: TEE may facilitate repair by confirming aortic pathology, identifying endograft placement, assessment of the adequacy of aneurysm sack isolation, as well as dynamic intraoperative cardiac assessment.  (+info)

Treating aneurysm patients with short aortic necks has been a long-time challenge for clinicians performing endovascular aneurysm repair (EVAR) to treat AAA patients, said Professor Giovanni B. Torsello, M.D., chief of Vascular Surgery, St. Franzkisus Hospital, M?nster, Germany and co-author of the PROTAGORAS study. The availability of a standardized approach which increases ...
October 23, 2018 -- Dublin -- Medtronic plc (NYSE:MDT) today announced it has received U.S. Food and Drug Administration (FDA) approval for the Valiant Navion thoracic stent graft system for the minimally invasive repair of all lesions of the descending thoracic aorta, including thoracic aortic aneurysms (TAA), blunt thoracic aortic injuries (BTAI), penetrating atherosclerotic ulcers (PAU), intramural hematomas (IMH), and aortic type B dissections (TBAD). Until now, patients with small iliac arteries were considered ineligible for thoracic endovascular aneurysm repair (TEVAR) or required adjunctive procedures to accommodate calcification and tortuosity concerns. Valiant Navion allows for the potential for more patients to receive a percutaneous procedure and overcome these anatomical concerns, enabling a less invasive approach to treatment compared to surgical cut-down (open) procedures. Our focus at Medtronic continues to be on advancing the treatment of complex aortic disease to improve ...

September 28, 2017-The US Food and Drug Administration (FDA) has issued a letter to health care providers advising that the agency is evaluating recent information regarding type IIIa and IIIb endoleaks with the use of endovascular graft systems indicated for endovascular aneurysm repair (EVAR) procedures. The letter, addressed to vascular and cardiothoracic surgeons, radiologists, and cardiologists, stated that an increase in the occurrence of type III endoleaks has been suggested by several sources, including the FDAs Medical Device Reporting system and the Annual Clinical Updates to Physicians by the manufacturers. This increase is compared with earlier clinical update reports in patients with various device models and implant duration lengths, including some patients who had previously stable repairs.. The purpose of the FDAs letter is to bring this potential complication to the attention of health care providers and to remind and encourage them to report type IIIa and IIIb endoleak events ...
Fenestrated and branched endovascular aortic repair (F/B-EVAR) is associated with a high degree of technical and clinical success. Despite this, studies have also reported high reintervention rates, and these are often related to the bridging stent grafts. Often new devices appear on the market before they have been tested in the bridging stent graft position. This review aims to assess the current literature on bridging stent grafts and discuss complications, illustrated by case reports. Complications reported with bridging stent grafts include; endoleak, kink, fracture, migration, occlusion, stenosis and perforation. Some known risk factors for bridging stent occlusions are renal artery stent grafts vs. SMA and celiac artery stent grafts. Some device specific complications have also been reported such as type IIIc endoleak with the Lifestream stent graft (Bard Peripheral Vascular, Tempe, AZ, USA) fractures and type IIId endoleaks with the 1st generation of Begraft (BentleyInnoMed, Hechingen, ...
Instead of open aneurysm repair, your vascular surgeon may consider a newer procedure called an endovascular stent graft. Endovascular means that the treatment is performed inside your artery using long, thin tubes called catheters that are threaded through your blood vessels. This procedure is less invasive, meaning that your surgeon will usually need to make only small incisions in your groin area through which to thread the catheters. During the procedure, your surgeon will use live x-ray pictures viewed on a video screen to guide a fabric and metal tube, called an endovascular stent graft (or endograft), to the site of the aneurysm. Like the graft in open surgery, the endovascular stent graft also strengthens the aorta. Your recovery time for endovascular stent grafting is usually shorter than for the open surgery, and your hospital stay may be reduced to 2 to 3 days. However, this procedure requires more frequent follow-up visits with imaging procedures, usually CT scans, after endograft ...
OBJECTIVE This study reports the early and midterm to long-term experience of chimney grafts (CGs) in urgent endovascular repair of complex lesions in the thoracic aorta. METHODS Twenty-nine high-risk patients (20 men) who were unfit for open repair were treated using CG technique for ruptured (n = 14) or symptomatic (n = 15) aortic lesions engaging the aortic arch itself (n = 9), the descending aorta (n = 10), or the thoracoabdominal aorta (n = 10). Twenty-two patients (76%) were treated urgently (≤24 hours) and seven were semiurgent (≤3 days). Of 41 chimneys used, 24 were placed in supra-aortic branches and 17 in visceral branches. Median follow-up (interquartile range) for the entire cohort was 2 years (0.6-3.8 years), 2.5 years (1-4 years) for 30-day survivors, and 3.5 years (1.9-6.4 years) for those who were still alive. RESULTS Four patients (14%) died ≤30 days of cerebral infarction (n = 1), visceral ischemia secondary to the initial rupture (n = 1), multiple organ failure (n = 1), or
Dr. Courtney M. Townsend, Jr. (right), President of the American College of Surgeons, presents Dr. Timothy A.M. Chuter (left) with the 2017 Jacobson Innovation Award. Between 1993 and 2000, there was rapid expansion in the scope of endovascular aneurysm repair including the first endovascular repair of a ruptured aortic aneurysm (1994), the first endovascular repair of an aortobronchial fistula (1995), the first bifurcated stent grafts (1993), the first inflammatory aneurysms (1995), the first fenestrated stent grafts for aneurysms of the pararenal aorta (1998), and the first branched stent grafts for the thoracoabdominal aorta (2000). Although none was the work of a single inventor, Dr. Chuters trailblazing work was pivotal in this rarefied period of surgical breakthroughs, not simply by his invention of new forms of endovascular aneurysm repair, but also through his mentoring of surgical residents, fellows, and faculty. Notably, Dr. Chuter has nurtured his inventions from conceptualization to ...
AccessGUDID - Fluency® Endovascular Stent Graft (04049519008639)- FLUENCY® PLUS Endovascular Stent Graft 12 mm x 40 mm (80 cm delivery system)
different portions of the stent/stent graft 10 are heat set at different diameters. For example, a braided material could be fabricated on a mandrel having a first larger diameter (e.g., 30-35 mm), which is generally the maximum diameter to which the stent/stent graft would be capable of expanding. The braided material may then be pulled down or compressed onto a mandrel having a second smaller diameter (e.g., 20-25 mm) and heat set such that the heat set stent/stent graft is capable of self-expanding to the diameter of the second smaller diameter. However, when the stent/stent graft 10 is axially compressed, the stent/stent graft is capable of expanding to the first larger diameter. Thus, in order to deploy the stent/stent graft 10, the distal end 34 of the stent/stent graft 10 may be positioned distally of the aneurysm 14 and as the delivery catheter 38 is retracted, the distal end of the stent/stent graft engages the lumen 12. As the stent/stent graft is further deployed in the region of an ...
Medtronic Receives FDA Breakthrough Device Designation for Developing Stent Graft System to Treat Thoracoabdominal Aortic Aneurysm - - Minneapolis (Minnesota)
In this issue of the Journal, Howell et al. (1)present some tuly remarkable results. Working in an interventional cardiology suite, they were able to implant the Medtronic AneuRx stent graft in all but one of 215 patients. Most of these patients had major comorbidity with an American Society of Anesthesiologists grade of IV or higher in 58.6% of patients. All these sick patients underwent stent-graft implantation under general anesthesia, yet only one patient suffered a non-Q-wave myocardial infarction, none died in the perioperative period, and most went home the next day.. One notable aspect of the technique described by Howell et al. (1)is the use of the Prostar XL device to facilitate percutaneous arterial closure. The 16F contralateral access site was closed this way in 174 of 188 attempts, and the 22F ipsilateral access site was closed in 26 of 27 attempts. Few centers have achieved such a high rate of success with percutaneous arterial insertion of large-bore sheaths. Indeed, one wonders, ...

N2 - Abdominal aortic aneurysms (AAAs) are a significant cause of morbidity and mortality worldwide whose incidence is increasing. Traditionally these aneurysms have been repaired by a standard surgical approach. Over the past decade, spurred by the development of endovascular therapies for a variety of vascular pathologies, the endoluminal treatment of AAAs has rapidly proliferated. Early stent-grafts used to treat AAAs were primarily home-made. Presently there are a number of industry-made devices available on both an investigational and approved for use basis and the number is growing. This review focuses on the types of stent-grafts currently available, indications for use and patient selection, as well as new patents issued over the years 1998 - 2000.

Abdominal aortic aneurysm repair has undergone a revolution since Volodos and Parodi described endoluminal repair in the early 1990s. Subsequent data from large registries have confirmed its efficacy. Randomised controlled trials have shown that although endoluminal repair may not be as cost effective as open repair, it can be performed with a lower mortality in patients fit for open repair. Some European countries (eg, Belgium) have taken the results of these trials to rationalise the number of hospitals able to do endovascular repair. The devices continue to improve and although most require open surgical access at present, in future percutaneous access will become the norm. This article reviews the current state of endoluminal aortic aneurysm repair in the infrarenal aorta. ...
Elective EVAR using the Cook Zenith endograft provides excellent results through a mean follow-up of |5 years. There is a low aneurysm-related mortality and an acceptable rate of postoperative complications and reinterventions. The occurrence of late complications throughout the follow-up period …
First generation aortic endovascular stent-grafts (EVG) had low applicability and were associated with a significant incidence of peri-procedural complications. With time, a number of EVG systems perished (some predictably) in a survival of the fittest. Improvements in design have been made as a result of these failures. Current designs have low peri-procedural morbidity and mortality and improving durability. This paper sets out to discuss the use of a variety of EVG for abdominal aortic aneurysm repair. The ideal properties of an EVG will be outlined along with some of the advantages and limitations of current, and, where appropriate, historical, commercially available stent-graft systems.. ...

RnRMarketResearch.com adds MediPoint: Aortic Stent Grafts - APAC Analysis and Market Forecasts to its store.. Aortic stent grafts are most commonly used to reinforce a weak spot in an artery, which is known as an aneurysm. The stent grafts are designed to seal tightly with the patients native artery above and below the aneurysm, and are used to treat abdominal aortic aneurysms as well as thoracic aortic aneurysms. Aortic aneurysms, as opposed to aneurysms found elsewhere in the body, are potentially very serious, as a burst aorta results in massive internal bleeding that can be fatal unless treated rapidly by an experienced emergency medical team. Since their introduction in patients in 1991, aortic stent graft devices have gained wide acceptance and availability, with their adoption fueled in great part by advances in stent-graft design and by a variety of devices for various anatomic features. Over time, these devices have gained traction for use in patients with ruptured aneurysms because ...

OBJECTIVE: To assess whether a strategy of endovascular repair (if aortic morphology is suitable, open repair if not) versus open repair reduces early mortality for patients with suspected ruptured abdominal aortic aneurysm. DESIGN: Randomised controlled trial. SETTING: 30 vascular centres (29 UK, 1 Canadian), 2009-13. PARTICIPANTS: 613 eligible patients (480 men) with a clinical diagnosis of ruptured aneurysm. INTERVENTIONS: 316 patients were randomised to the endovascular strategy (275 confirmed ruptures, 174 anatomically suitable for endovascular repair) and 297 to open repair (261 confirmed ruptures). MAIN OUTCOME MEASURES: 30 day mortality, with 24 hour and in-hospital mortality, costs, and time and place of discharge as secondary outcomes. RESULTS: 30 day mortality was 35.4% (112/316) in the endovascular strategy group and 37.4% (111/297) in the open repair group: odds ratio 0.92 (95% confidence interval 0.66 to 1.28; P=0.62); odds ratio after adjustment for age, sex, and Hardman index 0.94 (0.67
Boomington, Ind. ─ Cook Medical has received premarket approval from the U.S. Food and Drug Administration (FDA) for its lower-profile Zenith Alpha™ Thoracic Endovascular Graft. Zenith Alpha Thoracic is indicated for the endovascular treatment of patients with isolated lesions of the descending thoracic aorta (not including dissections) having vascular anatomy suitable for endovascular repair1. The approval of Zenith Alpha Thoracic was based on two pivotal clinical trials that studied the safety and effectiveness of the device in patients with aortic aneurysm/ulcer or blunt traumatic aortic injury.. Zenith Alpha Thoracic will allow physicians to treat more patients with TEVAR (thoracic endovascular aortic repair) because of its lower-profile introduction system and broad range of sizes. With a 16-20 French delivery system, Zenith Alpha Thoracic was developed to address vascular access issues associated with larger-profile devices and to increase conformability in tortuous anatomy..

An endovascular stent graft is placed inside the abdominal aortic aneurysm to help prevent rupture. Medtronic is a leading developer of endovascular stent grafts.
Aneurysms of thoracic aorta and abdominal aorta are rare and their treatment traditionally involved complex surgical repair with attendant morbidity and mortality. Nowadays, interventional non-surgical management with Endovascular grafting using covered stent grafts (EVAR : Endovascular Aneurysm Repair) has become the treatment of choice in the majority of cases. This is the tale of a 67 year old hypertensive gentleman with Coronary artery Disease presenting with very large saccular Aneurysm in
OBJECTIVE: The aim of this study was to describe our early experience in the treatment of ruptured abdominal aortic aneurysms with bifurcated endografts. We report on our initial twelve-month experience using this approach.

TY - JOUR. T1 - Endovascular management of abdominal aortic aneurysms. AU - Bush, R. L.. AU - Lin, P. H.. AU - Lumsden, Alan B.. PY - 2003/8/1. Y1 - 2003/8/1. N2 - An estimated 1.5 million people in the United States haves abdominal aortic aneurysms (AAAs) with more than 200 000 American diagnosed each year. The natural history of AAAs is to expand and rupture, accounting for an estimated 15 000 deaths per year. Thus, the major impetus for AAA repair is for prophylaxis against aneurysm-related death. The standard open surgical repair of AAAs is a well-established and durable procedure. However, as with all other major abdominal surgical operations, associated significant morbidity and mortality exist, along with prolonged recovery and various late complications. Furthermore, both mortality and morbidity increase significantly with advanced patient age and associated co-morbid disease states. Endovascular AAA repair using covered stent-grafts offers a significantly less invasive alternative to ...

Aortic aneurysm repair requires only a small incision in your artery. The surgeon will usually access your femoral artery, which is a branch of the aorta, by making a small incision in another part of your body, such as your groin. He or she will first insert a wire through the incision and into your femoral artery. The wire will help guide a long thin tube, called a catheter, through the inside of the arteries to the place of the aneurysm. The catheter can safely navigate through the inside of arteries; it reduces the risk of the procedure, allows for a quicker recovery , and reduces pain. Your arteries have no nerve endings so you should not feel any pain as the wire moves through them. The surgeon guides the catheter to the aneurysm and puts the stent graft into place to repair the weakness. Some stents slowly release medications to help prevent blood clots and other problems after the procedure. After the stent is securely in place, the surgeon removes the catheter, closes the incision ...

SCVS 2018 Abstracts: Statin Therapy is Associated with Higher Long-term, but not Perioperative Survival after Abdominal Aortic Aneurysm Repair
概述:The neck of a juxtarenal aneurysm is often too short for stable hemostatic stent-graft implantation. Fenestrations (holes) in the stent-graft permit implantation at a more favorable level by providing a route for flow to the renal arteries. In cases of pararenal and thoracoabdominal aortic aneurysm, the aorta around the renal and visceral arteries is too dilated for hemostatic contact with the wall of the stent-graft. There is a gap, which must be bridged by a branch of the stent-graft. In ...

Aortic aneurysm is a weak area in the aorta, the main blood vessel in the body that carries blood from the heart to the rest of the body. As blood flows through the aorta, the weak area bulges and grows over time. This bulging may eventually rupture. Aortic aneurysm in the abdominal region of the aorta is referred to as an abdominal aortic aneurysm (AAA). An aortic stent graft placement is a minimally invasive procedure in which a stent graft is placed inside the aneurysm, creating new walls over the weak spot in the vessels. This graft redirects blood flow to stop the pressure on the weak vessel wall to prevent rupture.. ...
BACKGROUND: The chimney technique has been successfully used to treat juxtarenal aortic aneurysms. The two main issues with this technique are gutter formation and chimney graft (CG) compression, which induce a risk for type Ia endoleaks and stent thrombosis, respectively. In this benchtop study, the geometry and renal artery flow of chimney endovascular aneurysm repair configurations were compared with chimney configurations with endovascular aneurysm sealing (ch-EVAS). METHODS: Seven flow phantoms were constructed, including one control and six chimney endovascular aneurysm repairs (Endurant [Medtronic Inc, Minneapolis, Minn] and AFX [Endologix Inc, Irvine, Calif]) or ch-EVAS (Nellix, Endologix) configurations, combined with either balloon-expandable or self-expanding CGs with an intended higher positioning of the right CG in comparison to the left CG ...

BACKGROUND: Fenestrated endografts are customized, patient-specific, endovascular devices with potential to significantly reduce morbidity and mortality of short-neck infrarenal and juxtarenal abdominal aortic aneurysm repair. The Zenith fenestrated endovascular graft (ZFEN) for abdominal aortic aneurysms (Cook Medical, Bloomington, Ind), Food and Drug Administration-approved in 2012, remains the only fenestrated device available in the United States. This technology is among the most technically complex catheter-based procedures and, therefore, inherently associated with serious risk for device-related complications. We sought to define patterns of physician and hospital adoption of ZFEN. METHODS: Deidentified datasets containing numbers of physicians trained, orders by physicians and hospitals, and designs (fenestration/scallop configuration) was provided for U.S. ZFEN devices ordered (April 2012-August 2015). We evaluated the number of physicians trained, the number of devices ordered, hospital

  • Mechanically challenged tissue-engineered organs, such as blood vessels, traditionally relied on synthetic or modified biological materials for structural support. (nih.gov)
  • In this report, we present a novel approach to tissue-engineered blood vessel (TEBV) production that is based exclusively on the use of cultured human cells, i.e., without any synthetic or exogenous biomaterials. (nih.gov)
  • These medications work by increasing tissue sensitivity to the blood-vessel-dilating substance nitric oxide (NO) in the penis. (epnet.com)
  • These features include the structural components collagen and elastin, which are responsible for the tensile strength and viscoelasticity of the blood vessel, and create a fatigue-resistant tissue with long-term durability [ 9 ]. (pubmedcentralcanada.ca)
  • Furthermore, the endothelial lining in the native vasculature not only serves as a protective, thromboresistant barrier between blood and the surrounding tissue, but also controls vessel tone, platelet activation and leukocyte adhesion. (pubmedcentralcanada.ca)
  • The first tissue-engineered blood vessel substitute was created by Weinberg and Bell in 1986 [ 10 ]. (pubmedcentralcanada.ca)
  • Each group can be further organized into tissue-engineering strategies for in situ vascular regeneration, in which the body's natural healing response is modulated by material design and fabrication, or strategies for ex vivo formation of a blood vessel substitute, whereby in vitro culture of human cells on polymer substrates before implantation defines their mechanical and biological properties.
