Treatment of endoleaks after thoracic endovascular repair remains challenging, particularly when the proximal landing zone is small and partly includes the origin of the neck vessels. We report a Type Ia endoleak, occurring after thoracic endovascula
Background: Despite recent technical advances in endovascular recanalization, there is skepticism regarding its clinical effectiveness compared with intravenous thrombolysis for treating acute ischemic stroke. We aimed to delineate its effectiveness and safety and their change over time. Methods: Using a prospective, multicenter stroke registry database, we identified 872 patients with ischemic stroke who underwent recanalization therapy with intravenous thrombolysis alone (IVT; n = 533) or endovascular recanalization with or without intravenous thrombolysis (EVT; n = 339) between April 2008 and January 2012. All subjects had National Institute of Health Stroke Scale score of 10 or more and arrived at the hospital within 4.5 hours of onset. Propensity score was used to address baseline imbalances between treatment groups, but balance adjustment was not performed for subgroup analyses. Results: The primary outcome was modified Rankin Scale score of 0-2 at discharge. The year-by-year effectiveness ...
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.. The ...

January 12, 2016-Findings from a study on the management and outcomes of isolated renal artery aneurysms (RAAs) in the endovascular era were published by Dominique B. Buck, MD, et al in the Journal of Vascular Surgery (JVS; 2016;63:77-81). The background of the study is that isolated RAAs are rare, and controversy remains about indications for surgical repair; however, little is known about the impact of endovascular therapy on patient selection and outcomes.. The investigators concluded that more RAAs are being treated due to the advent of endovascular techniques, without a reduction in operative mortality or a reduction in open surgery, and therefore, indications for repair should be re-evaluated.. As summarized in JVS, the investigators identified all patients undergoing open or endovascular repair of isolated RAAs in the Nationwide Inpatient Sample from 1988 to 2011 for epidemiologic analysis. Elective cases were selected from the period of 2000 to 2011 to create comparable cohorts for ...
Greenhalgh spoke to the audience about innovations and challenges to innovation in collecting data. He presented insights from the European Vascular and Endovascular Monitor, a consumption-based monitor covering 200 centres from Western Europe. He said that the advantage of a monitor approach was that it was enduring and effective in rapidly-shifting markets.. From the thoracic market, data showed that thoracic endovascular aneurysm repair remains the "gold standard" and that the current issues in the thoracic field were the size of the aneurysm, and the perceived need for a screening programme. For carotid procedures, Greenhalgh said the data indicated open surgery as the gold standard and that endovascular procedures were focused in the German and Italian markets.. "Endovascular procedures continue to grow at the expense of open surgery," Greenhalgh commented on aortic-iliac procedures and femoropopliteal, with the use of drug-eluting balloons on the increase in the latter. Hefsyv identified ...
Chronic MCA occlusion as a cause of hemodynamic ischemic stroke is not a prominent clinical issue worldwide.1 While acute occlusion of the MCA is commonly caused by an embolic thrombus,3 4 atherosclerotic occlusion of the intracranial arteries is more prevalent in Asians. Patients with chronic proximal MCA occlusion may have minor or no stroke because of well developed collaterals. Conversely, the prognosis for those with hemodynamic impairment is poorer.1 Chronic occlusive lesion does not seem to represent a significant embolic source but threatens the patient with hemodynamic ischemia and infarct. In addition, patients with MCA occlusion may have disabling cognitive impairment, especially for those with bilateral diseases.5 For our two patients, the etiology of their recurrent TIAs was likely to be hemodynamic impairment from total MCA occlusion, arising from atherosclerotic stenosis and superimposed thrombosis based on angiographic findings. The optimal management of them was ...
The Zenith® Thoracic Dissection Study is a clinical trial to study the safety and effectiveness of the Zenith® Dissection Endovascular System in the treatment of dissections (length-wise tear) of the descending thoracic aorta. The Zenith® Dissection Endovascular System is comprised of the Zenith TX2® TAA Endovascular Graft and the Zenith® Dissection Endovascular Stent. Instead of making a large incision in the chest, the physician makes a small incision near each hip to insert, and guides the graft and the dissection stent into place in the aorta ...
Prior to endograft deployment, the position of all arch branches was ascertained by arteriography using a pigtail catheter inserted from left femoral arterial access. The endograft was then deployed, but it remained partially constrained because of the DLTs. Partial constraint of the endograft and traction towards the inner aortic curvature (using ETAG) were necessary to leave space for the cannulation of fenestrations from the side of the outer aortic arch curvature. The IA and LCCA fenestrations were cannulated (the LSA had been pre-cannulated) and covered stents positioned within all three and kept ready for deployment: BeGraft 14 × 38 mm (Bentley InnoMed GmbH, Lotzenäcker 25, 72379 Hechingen, Germany) via 12 Fr/45 cm guiding sheath (Flexor Ansel, COOK Medical, Bloomington, IN 47402-4195 USA) in the IA, Advanta 12 × 29 mm (Getinge, 40 Continental Blvd, Merrimack, NH 03054, USA) via 9 Fr/45 cm guiding sheath (Flexor Ansel, COOK Medical) in the LSA and BeGraft 7 × 38 mm via 7 Fr/90 cm ...

We describe a technique to gain an additional endovascular access in acute situations in which a large-bore introducer is already inserted or in situations in which multiple accesses are impaired because of other reasons. Using an existing percutaneous femoral artery access, a second guide wire is inserted into the introducer, which is later withdrawn and applied onto one of the two guide wires. A double-wire access is then achieved. This access can be used, for example, for angiography or embolization catheters. This method might be useful in situations in which a quick and unplanned extra access is needed. It is, for example, applicable in hemodynamically unstable patients in whom percutaneous access can be difficult to obtain or in aortic endovascular procedures when an unplanned access is needed to insert an additional catheter for angiography and embolization ...

Between December 2014 and April 2015, five multicenter randomized clinical trials were published with positive results with endovascular therapy. The major differences between these positive endovascular trials and past trials were the use of computed tomography angiography (CTA) to select patients with proximal intracranial occlusion and the use of stent retrievers for thrombectomy in the majority of cases ...
CLI is usually treated by operations or procedures that increase blood flow to the leg and foot, in order to relieve these symptoms, heal the ulcers, and preserve the limb. There are two different ways to increase the blood flow in CLI. One is with open surgery, which creates a bypass around the blockage. The other is with endovascular treatment (often called angioplasty), a minimally invasive procedure that opens the blocked arteries directly. Angioplasty is performed with balloons and other tools that clear plaque, and sometimes permanent implantation of small, mesh-like metal tubes called "stents". Both types of treatment - open surgery and angioplasty - are considered reasonable and appropriate for patients with CLI like you. The study doctors have determined, on the basis of your medical history and tests, that you are eligible for both treatments ...

1. Parallels in the evolution of x-ray angiographic systems and devices used for minimally invasive endovascular therapy Charles Strother - DSA, invented by Dr. Charles Mistretta at UW-Madison, was the technology which enabled the development of minimally invasive endovascular procedures. As DSA became widely available and the potential benefits for accessing the cerebral vasculature from an endovascular approach began to be apparent, industry began efforts to develop tools for use in these procedures. Along with development of catheters, embolic materials, pushable coils and the GDC coils there was simultaneous development and improvement of 2D DSA image quality and the introduction of 3D DSA ...

Thoracic endovascular aneurysm repair (TEVAR) is a safe and effective procedure for the treatment of thoracic aortic aneurysms (TAAs).
To gain knowledge into how endovascular therapies have been utilized, and the clinical outcomes resulting from these procedures, the group from across the US and Canada set out to review the Get With The Guidelines Stroke data from 1087 hospitals from 2003 to 2013. The type of endovascular therapy has evolved over time from initially being more geared toward intra-arterial fibrinolysis and angioplasty/stenting to later on in the data set where techniques of mechanical clot and stent retrievers were used. The authors found that 454 hospitals (41.8%) provided endovascular therapy to at least one patient during the study period and that a total of 1.6% of all ischemic stroke patients received endovascular therapy. During the same period, 8.0% of all of the ischemic stroke patients received IV TPA alone without endovascular therapy. In general, there was an increase over time of the proportion of hospitals providing endovascular therapy from 2003 to 2012, with a drop in 2013. Along the same lines, ...
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 ...
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 ...
Learn about EVAR (Endovascular Aortic Repair) for aortic aneurysm treatment at Wake Forest Baptist in Winston-Salem, North Carolina.
To the Editor:. Using percutaneous catheter techniques and endovascular grafts, Ince et al1 reported successful treatment of aneurysms occurring after previous repair of aortic coarctation with no mortality and minimal morbidity in 6 patients. They contrasted these results with those reported for similar patients with open surgical treatment, in whom the mortality rates ranged between 14% and 23.5%. The 3 references reporting these outcomes were published between 1989 and 1996.. Any comparison of these 2 methods of treatment for recurrent aneurysm after coarctation repair should include contemporary reports that use modern surgical techniques. Two recent studies using the technique of full cardiopulmonary bypass and circulatory arrest in 9 patients with complications following surgical repair of aortic coarctation (including 7 patients with aneurysms or pseudoaneurysms) reported no early deaths and few major complications.2,3. Although minimally invasive endovascular techniques offer important ...
April 2, 2009 - Researchers from the University of Massachusetts Memorial Medical Centers division of vascular and endovascular surgery, 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.. Study results are published in the April issue of the Journal of Vascular Surgery.. In the study, an estimated 27,750 hospital discharges for RAAA occurred, of which 11.5 percent were treated with EVAR. Data was secured through the Nationwide Inpatient Sample to evaluate operative outcomes.. "While the incidence of RAAA remained fairly constant, EVAR was used to treat RAAA in an increasing proportion of patients - from 5.9 percent in 2001 to 18.9 percent in 2006," said Andres Schanzer, M.D., assistant professor of surgery in the division. Researchers found that EVAR was independently associated with a lower postoperative ...
Background: Endovascular therapy seems to benefit a subset of patients with acute large vessel occlusions (LVO). The aim of this study was to develop a clinically useful tool to identify patients with anterior circulation large vessel occlusions who are likely to benefit from endovascular therapy.. Methods: Adults with anterior circulation LVOs were included. In the derivation cohort (2008-2012) from Grady Memorial hospital (GMH), independent predictors (p,0.2) of good outcome (mRS 0-2 at 90 days) were determined using logistic regression. Highly weighted factors were used to derive the PRE score as a predictor of good outcome. Four risk-quartiles were created based on observed rates of good outcomes. The PRE score was validated in the UPMC database (n=322, 2007-2013) and in a database from Unitat dIctus Vall dHebron (UIVH), Barcelona (n=203, 2009-2012). Performance of PRE was compared with HIAT-2, THRIVE and ASPECTS in predicting good outcome.. Results: In the derivation cohort (N=247, mean ...
A novel endovascular approach useful in the treatment of aneurysms, particularly saccular aneurysms. The present endovascular prosthesis comprises a leaf portion capable of being urged against and blocking the opening of the aneurysm thereby leading to obliteration of the aneurysm. The leaf portion is attached to, and independently moveable with respect to, a body comprising at least one expandable portion. Thus, the body serves the general purpose of fixing the endovascular prosthesis in place at a target body passageway in the vicinity at which the aneurysm is located and the leaf portion serves the purpose of blocking the aneurysmal opening thereby leading to obliteration of the aneurysm. A method of delivering and implanting the endovascular prosthesis is also described.

Background: Serial ASPECTS of ischemic stroke lesion evolution from baseline to 24-hours has been established as an effective surrogate endpoint in endovascular therapy. The use of this imaging shift has not been implemented beyond thrombectomy trials to estimate impact of endovascular therapy in large-scale registry data.. Methods: The STRATIS Imaging Core Lab, blind to all clinical data, independently determined ASPECTS scores on baseline and 24-hour studies. ASPECTS regional involvement and resulting total scores were analyzed in anterior circulation occlusions in STRATIS. Statistical analyses calculated the proportion of subjects with 0 ASPECTS score shift and separately, those with shifts ,4, 5, 6 points. Clinical predictors of ASPECTS shift and regional involvement were determined.. Results: Baseline ASPECTS (n=517) was 8.2 ± 1.59 (median 8.0 (2, 10)) and 24-hour ASPECTS (n=547) was 6.0 ± 2.92 (median 7.0 (0, 10)). Serial ASPECTS (n=487) revealed change of -2.1 ± 2.41 (median-1.0 (-10, ...

In 2008, the top priority in our divisions 5-year strategic plan was to become an internationally recognized center of excellence for the endovascular treatment of complex aortic pathology extending from the aortic valve to the external iliac artery. Five components were identified as most critical to achieve this strategic priority: (1) training at centers of excellence in complex endovascular repair; (2) industry partnership to improve access to developing technologies; (3) a fully integrated team approach with one leader involved in all steps of all cases; (4) prospective data collection; and (5) development and implementation of a physician-sponsored investigational device exemption for juxtarenal, pararenal, and thoracoabdominal aneurysms. We have now performed 49 repairs (16 commercially manufactured devices, 33 physician-modified devices) for 3 common iliac, 20 juxtarenal, 9 pararenal, and 17 thoracoabdominal aneurysms, using 142 fenestrations, branches, and scallops.
