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)

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 ...
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, ...

Renal and hypogastric artery localization and completion angiography were done with CO 2 in all patients, including additional arterial embolization in 16 cases. ...
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. ...

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.. ...

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 ...

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 ...

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

RESULTS:: From 104 patients selected, 4 (3.8%) preferred primary hospitalization and were excluded from further analysis. Four patients (4%) with access vessel complications required additional procedures and had to be hospitalized overnight. The 30-day readmission rate was 4% (4), all due to access vessel stenosis (2) or false aneurysm (2). There was no 30-day mortality. From the 96 outpatients who completed Outpt EVAR, 93 (97%) would undergo Outpt EVAR again and would recommend it to others. Cost comparison showed in 42 matched contemporary patients treated with just a standard stent graft that costs were significantly lower in 21 Outpt EVAR patients than in 21 inpatient EVAR ...
An endoluminal graft includes a unitary tube of graft material forming two adjacent legs that are integral and monolithic to each other. The graft can be part of a prosthesis assembly for treatment of branched vascular systems and can function as an integral bifurcated leg extension prosthesis in combination with a main bifurcated prosthesis. In treating abdominal aortic aneurysms, the graft can be deployed within both iliac arteries.

The use of endovascular aneurysm repair (EVAR) in the treatment of abdominal aortic aneurysms has advanced from a premature characterization as a "failed experiment" in early 2000 to the predominant modern method of treatment. Technology has accommodated initial shortcomings, but it has also led to expansions in the treatment of ruptured aneurysms and complex aortic pathologies. The overall aim of this thesis is to characterize the contemporary utilization of endovascular repair in the international setting and to evaluate its expanding use in complex aortic disease treatment.. Paper I is an analysis of outcomes after intact aneurysm treatment from registries of 12 countries. From 2005 to 2013, and with 83,253 patients included, it was shown that the use of EVAR has increased while, the perioperative mortality has decreased. This was counterbalanced by a worsening mortality for those patients treated with open aortic repair.. Paper II is an analysis of ruptured aneurysms from the above-mentioned ...
In an attempt to chart the changing rates of open, EVAR and branched/fenestrated EVAR repairs over the past decade, Suckow and colleagues used a query of Medicare claims data from 2003-2013 involving abdominal aortic aneurysm repairs (excluding open repairs with any thoracic component but including juxta-/pararenal procedures).. The data gathered showed a 20% decline in all forms of abdominal aortic aneurysm repair to approximately 24,000 repairs in 2013 following a peak of approximately 30,000 in 2005. Breaking these figures down by procedure type, the number of EVAR procedures grew by 74% from 2003-2008 before falling by 13% to 2013. Open repair saw a prolonged and significant decline from 2003 to 2013, falling by 78%. Less than 4,000 open repair Medicare procedures were completed in 2013, Suckow said. Branched/fenestrated EVAR-first coded by Medicare in 2011-has since increased by 504% and by 2013 was as common as open repair.. As well as looking at the total number of repairs, the team also ...
An apparatus for endovascular repair of aortic aneurysms is disclosed. In one form, the apparatus includes a tube and an anchoring unit that includes a plurality of thin lines. The tube serves as a conduit for blood flow in an aneurysm of an aorta. First end of the lines are connected to a first end of the tube. Second end of the lines are separated by a distance from the first end of the tube for anchoring the apparatus at a location away from the aneurysm.
A flexible low profile delivery system for delivery of an expandable intracorporeal device, specifically, an endovascular graft, which has at least one belt circumferentially disposed about the device in a constraining configuration. The belt is released by a release member, such as a release wire, by retracting the wire from looped ends of the belt. Multiple belts can be used and can be released sequentially so as to control the order of release and placement of the endovascular graft. An outer protective sheath may be disposed about the endovascular graft while in a constrained state which must first be retracted or otherwise removed prior to release of the graft from a constrained state. The delivery system can be configured for delivery over a guiding device such as a guidewire. The delivery system can also be configured for delivery of bifurcated intracorporeal devices.

The utilization of endovascular abdominal aortic aneurysm repair (EVAR) in suitable patients has resulted in decreased perioperative morbidity and mortality. Octogenarians as a subgroup have been more readily offered EVAR, as it is less invasive, and
Several large-scale trials comparing EVAR to open surgery for AAA have been published. Short-term surveillance consistently shows better outcomes for EVAR in respect to mortality. Also, EVAR is milder on patients and better tolerated. However, a well known advantage for open repair of AAA is that it is durable. Less surveillance is needed for these patients in comparison to patients undergoing EVAR. This makes open repair a preferred option for younger, healthier patients who can withstand the procedure and are believed to have a long life expectancy.. The EVAR 1 trial was a prospective, randomized trial comparing EVAR to open repair of AAA in over 1200 patients. In 2010 long-term follow-up was reported (median of 6 years). As expected, peri-procedural mortality was greater with the open repair (6%) than in the endovascular repair (2.3%). These short-term benefits remained at 6 months, but disappeared within 4-6 years, a time at which aneurysm and total mortality curves converged for both ...
A randomized trial found that patients had similar rates of survival and quality of life whether they underwent elective open and endovascular repair of their aortic abdominal aneurysm (AAA). The procedures also had similar costs and cost-effectiveness ratios.
A radially expandable endoluminal stent-graft assembly (10) and a method and apparatus for making the same are described. The stent-graft assembly (10) includes a tubular radially expandable stent (12) circumferentially covered by a tubular graft (14) which is retained about the stent (12) by inherent radial recoil forces of the tubular graft (12) and without the need for adhesives or sutures to retain the graft (14) on the stent (12). The assembly apparatus (44) for making the expandable stent-graft assembly (10) consists generally of a tapered dilation mandrel (46), a stent retaining mandrel (52), a handle (53), and couplings (60, 71) for removably and coaxially coupling the components of the assembly apparatus mandrel (44). The method for making the expandable stent-graft assembly (10) utilizes the assembly apparatus (44) to make the stent-graft assembly (10) by dilating the graft (14) on the tapered dilation mandrel (46), sliding the dilated graft (14) over a stent (12) retained on the stent
In the meeting international experts, with the most significant experience in endografting, often gained from constant involvement in this activity for almost a decade, discuss the critical issues in endografting. The best available, most up-to-date information and data are used in presentations, and discussions that follow are in depth. Most importantly, consensus reached has a large bearing on what happens in endografting throughout the world over the year that follows the meeting. What direction will endografting take following this most recent meeting? A decade on in endografting from its introduction, data from early generation devices show the pattern of success or failure, depending on how one wishes to look at it. Nearly all of the experts at the meeting are convinced that endovascular exclusion of aneurysms is a viable alternative to aortic surgery and only a few believe they should continue with caution. Is it that they have got used to the occasional catastrophic device failure? Is it ...

An endoluminal stent is formed in a modular construction to include at least one elongate spine and a plurality of general tube-defining modules attached to the spine, or spines, in a longitudinal array. The modules are constructed along a spine-like structure so as to form a bifurcate shape for implantation in branching or bifurcating vessels. Each module defines, in cooperation with a spine, a closed ring-like structure. Each of the modules is radially expandable from a reduced diameter, low profile configuration, in which it is readily navigated through the body passages, to an expanded diameter engageable with the inner luminal surface of the body lumen. The stent, being of modular construction, can be built to individual specifications for a specific patient. Modules are formed from a wire shaped in a flat serpentine configuration that is then wrapped in a cylindrical configuration with its free ends connected to a spine. The modules are expandable, as by a balloon, from a low profile to an

Introduction: Endovascular aneurysm repair (EVAR) has been an established treatment for abdominal aortic aneurysm (AAA). Although statin use has been shown associated with better long-term survival following open AAA surgery, its impact on EVAR has not been systematically explored.. Methods: We retrospectively analyzed a multicenter database of 368 consecutive patients (age, 76 ± 8 years; 84% male) undergoing EVAR for AAA between November 2006 and December 2013. The outcome measure was overall survival following EVAR. Independent predictor associated with the outcome was assessed by Cox proportional hazard regression model. Furthermore, the association between the statin use and the outcome was assessed.. Results: During the follow-up of 30 ± 20 months, 38 patients died from cardiovascular disease (33%), cancer (23%) or infection (23%). Survival rate was 96% and 81% at 1 and 5 years, respectively. In Cox regression analysis, statin use (in 213 AAA patients, 58%) was negatively associated with ...
PURPOSE: To present a technique for renal and visceral revascularization allowing complete endovascular treatment of a ruptured type IV thoracoabdominal aneurysm using devices already stocked in most centers performing endovascular aneurysm repair. TECHNIQUE: Open arterial access is obtained to both common femoral arteries and the left subclavian artery (LSA). Access to the visceral and renal arteries is obtained through separate 8-F sheaths for each visceral and renal branch. Both visceral arteries (celiac trunk and superior mesenteric artery) are accessed through 2 separate sheaths placed into the LSA, and both renal arteries are accessed through 2 separate sheaths placed into the left common femoral artery. Corresponding covered stents are introduced and positioned in the celiac trunk, superior mesenteric artery, and both renal arteries but not deployed. The aortic stent-graft is then introduced and deployed through the right common femoral artery. Once the aneurysm exclusion is completed, ...
OBJECTIVE: The purpose of this study was to assess whether there is a difference in outcome of endovascular repair in patients with and without intraoperative adjuvant procedures. METHODS: Demographic, anatomic and operative details were assessed in patients undergoing endovascular repair using the EUROSTAR registry and correlated with morbidity and mortality rates. Three groups of adjuvant procedures: (A) endovascular, (B) surgical peripheral arterial and (C) surgical abdominal arterial were compared with a group of patients without an adjuvant procedure (D). Logistic regression and Cox proportional hazards model were used for statistical analysis. RESULTS: Of 4631 endovascular repairs, 1353 patients (29.2%) required adjuvant procedures. Additional endovascular procedures were performed in 1057 (78.1%), surgical peripheral arterial in 193 (14.3%) and surgical abdominal arterial in 103 (7.6%). The 30-day mortality rate was significantly higher in categories with peripheral arterial surgical ...
Once an abdominal aortic aneurysm reaches a particular size, treatment is recommended to prevent its rupture. An abdominal aneurysm can be treated by open surgery or by minimally invasive endovascular technique. Open surgery requires a large incision in the abdomen and replacement of the dilated portion of the aorta with a synthetic blood vessel. In endovascular repair, an interventional radiologist makes a small incision in the groin, which serves as an entry point for a thin wire catheter that is guided through the femoral artery to the dilated portion of the aorta using advanced medical imaging. Once in place, a stent graft that is compressed into the catheter is opened up and the edges of the stent push against the aortic wall and stays in place. Blood flows through the stent graft instead of the abnormally dilated aorta and prevents it from rupturing ...
April 1, 2009 - Endovascular aortic repair (EVAR) used to repair ruptured abdominal aortic aneurysms (RAAAs) had a significant mortality benefit, according to five-year study published in the April issue of the Journal of Vascular Surgery.. The study, conducted by researchers from the University of Massachusetts Memorial Medical Centers division of vascular and endovascular surgery in Worcester, examined the national frequency, predictors, outcomes, and the effect of institutional volume metrics in cases where endovascular aortic repair (EVAR) was used to repair ruptured abdominal aortic aneurysms (RAAAs) between 2001 and 2006.. Over the years EVAR has gained wide acceptance for the elective treatment of abdominal aortic aneurysms (AAA). This success has led to increased interest in similar treatment of RAAAs, because most patients who suffer a RAAA do not survive long enough to obtain medical care. The mortality rate for patients who do survive and undergo traditional open surgical repair ...
Long-term outcome of ruptured abdominal aortic aneurysm: impact of treatment and age Jelle W Raats,1 Hans C Flu,1 Gwan H Ho,1 Eelco J Veen,1 Louwerens D Vos,2 Ewout W Steyerberg,3 Lijckle van der Laan1 1Department of Surgery, Amphia Hospital, Breda, 2Department of Radiology, Amphia Hospital, Breda, 3Department of Public Health, Erasmus MC, Rotterdam, the Netherlands Background: Despite advances in operative repair, ruptured abdominal aortic aneurysm (rAAA) remains associated with high mortality and morbidity rates, especially in elderly patients. The purpose of this study was to evaluate the outcomes of emergency endovascular aneurysm repair (eEVAR), conventional open repair (OPEN), and conservative treatment in elderly patients with rAAA.Methods: We conducted a retrospective study of all rAAA patients treated with OPEN or eEVAR between January 2005 and December 2011 in the vascular surgery department at Amphia Hospital, the Netherlands. The outcome in patients treated for rAAA by eEVAR or OPEN repair

Interventional radiology is often misunderstood, but the alternatives it presents are changing the way patients deal with abdominal and thoracic aortic aneurysms. In the past, surgery was required to repair ruptures, but the mortality rate was significantly higher when compared with newer medical data on EVAR. The endograft procedure, a minimally invasive, non-surgical alternative, is revolutionizing the ways physicians provide treatment to their patients. Endovascular stenting is still a relatively new response to the threats posed by AAAs and TAAs - our physicians performed the first wall stent in 1986, and the procedure has only recently been offered in other parts of the world in the last few years.. The life-saving endograft procedure, an emerging alternative treatment for a thoracic or abdominal aortic aneurysm, is gaining ground due to its faster recovery time, shorter hospital stay, and decreased mortality rates. For patients unable to tolerate general anesthesia, theres another ...

Background. Complete resection of the intimal tear in aortic arch is one of the most complicated tasks in the treatment of aortic dissections. We introduced open stent grafting technique to complete this task with technical easiness. In this study we evaluated the long term efficacy of this procedure from our 12 years experience.. Patients and Method. Form January 1994 to December 2004, 59 aortic dissections with intimal tear in aortic arch or proximal descending aorta were operated with open stent grafting technique (age 61.7yrs, 41 type A and 18 type B). Thirty three (55.9%) were in emergency status. All these cases were morphologically excluded from the indication of transluminal endovascular repair. Under deep hypothermic circulatory arrest with antegrade cerebral perfusion, the hybrid prosthesis was inserted into descending aorta through the transected proximal aortic arch in order to achieve intimal tear exclusion.. Results. Complete exclusion of the aortic arch intimal tear was achieved ...

Current management and outcome of chronic type B aortic dissection: results with open and endovascular repair since the advent of thoracic endografting
Results Thirty patients underwent LSA embolization during TEVAR. Six CCEs in 6 patients were performed from June 2013 to November 2013, while twenty-four CAEs in 24 patients were performed from December 2013 to March 2016. Technical success was achieved in all patients in both groups. No embolization-related complications or type II endoleaks from LSA were recorded during the follow-up period in all patients. In both groups, all embolic materials were detected in the proximal portion of the LSA from the LSA orifice to the vertebral artery origin and no vertebral artery occlusions were detected. The mean compression ratio of AVP II was 58 ± 5.9% of predicted length of standard procedure. In the CAE group, one AVP II was sufficient to achieve complete LSA occlusion in all patients. On the other hand, multiple coils (10.2 ± 2.7) were used in the CCE group (P , .01), resulting in a significantly lower cost incurred in the CAE group (CAE: 129,000 JPY vs. CCE: 639,600 ± 140,060 JPY; P , .01 ...
An aortic aneurysm is a dilation of a segment of the aorta where the wall of the vessel becomes thin and weak. The most common site involves the abdominal aorta below the arteries to the kidneys. The main risk of an aortic aneurysm is rupture. If the aneurysm ruptures, the chance for survival is very low. If the aneurysm is repaired before rupture, the chance of survival is very good. In general, an abdominal aortic aneurysm should be repaired when it reaches a size of 5 centimeters in diameter. On average, an aortic aneurysm will increase in size 0.5 centimeters per year. A more rapid rate of enlargement might lead us to recommend repair before the aneurysm reaches 5 centimeters. There are currently two acceptable methods used to repair an abdominal aortic aneurysm. The most common method involves making an incision in the abdomen and directly exposing the aneurysm. The involved section of aorta is completely replaced with a prosthetic fabric tube. This operation is highly effective at reducing ...
As both APTT and APTT-based coagulation method cannot distinguish heparin effect from intrinsic coagulation factor deficiency, we implemented thromboelastography (TEG) for the coagulation assessment in a patient with hemophilia A undergoing an endovascular surgery with heparinization. A 68-year-old male with hemophilia A underwent endovascular aortic repair for abdominal aortic aneurism. TEG results showed recovery of coagulation time (R) in both kaolin assay (CK) and kaolin-heparinase assay (CKH) after factor VIII replacement before heparinization. Against our expectations, R-CKH was slightly prolonged (9.0 min) during heparinization. After the administration of protamine sulfate, R in both assays showed similar values within the normal ranges. The combination of CK and CKH assays could be useful to estimate factor VIII (FVIII) level when heparin concentration is low or without heparin; however, caution should be necessary for estimation of FVIII level by TEG under the effect of medium- or high-dose

  • For example, tubular conduits are used to repair lumens such as in the esophagus and colon areas, and in particular, prostheses are used in the vascular system to repair, buttress or replace a weakened section of the vessel. (google.es)
  • The prosthesis includes a distal fixation member, configured to be positioned in a downstream artery, and to apply a first axial force directed toward a ventricle. (freepatentsonline.com)
  • A transmyocardial implant with a myocardial leg including point of minimum diameter and a first end with a larger diameter, and a vessel leg in fluid communication with the myocardial leg. (google.ca)
  • Antithrombogenicity is important when the diameter of vascular prostheses become small for satisfactory patency. (nii.ac.jp)
  • At the previous NATO ASI on angiogenesis we delineated the ongoing attempts by us and others to restore "nature's biocompatible blood container" through " factitious angiogenesis ", i.e., by precoating the luminal surfaces of these prostheses with a functional, nonthrombogenic monolayer of autologous endothelial cells (ECs) prior to implantation (Lelkes et al .1992).

  • The effect of sodium thiopental on mean arterial blood pressure during cardiopulmonary bypass was assessed in 150 patients undergoing elective coronary artery bypass grafting [ncbi.nlm.nih.gov] […] after LMA insertion . (symptoma.com)
  • Secondary outcomes included: operative duration, hospital stay, time to ambulation, blood loss, cost and late loco-regional complications (defined as any event that led to delayed healing, additional intervention or follow-up). (york.ac.uk)
  • Most of these complications can be traced back to the inadequate hemocompatibility of the (polymeric) blood contacting surfaces in these devices. (springer.com)
  • Cementless stems help reduce two major complications of hip replacement, namely, chances of infection and loosening of the prosthesis. (openpr.com)
  • Another type that is less utilized in hernia surgery is polyethylene-terephtalat (PET), which faces complications in that fact that it easily degrades after some years of implantation, erasing the effects of the surgery. (wikipedia.org)
  • The mainly risk factor to infection was blood transfusion, followed by drug injection. (rmmg.org)
  • Adcirca (tadalafil) is a medicine accepted by the U.S. Meals and Drug Administration to treat pulmonary arterial hypertension (PAH), which is high blood pressure in the arteries surrounding the lungs, and Raynaud's phenomenon , a contraction or spasm of the small blood vessels within the arms and ft. (miskin.fr)
  • During an erection, the endothelial cells release nitric oxide, which makes the smooth muscle tissue relax, permitting an influx of blood into the penis. (thundersplace.org)
  • Furthermore, the rejection process per se is not abrogated, and often it manifests itself in the form of accelerated atherosclerosis in the blood vessels of the transplanted tissues (Mills et al . (springer.com)
  • METHODS AND RESULTS: Genotypes were determined in a series of consecutive patients who underwent conventional balloon coronary angioplasty without stenting (n=287) or who also had successful implantation of a Palmaz-Schatz stent (stent) (n=198). (ucl.ac.uk)
