To assess hemodynamic disturbances to the ostia of the renal arteries generated by the implantation of EVAR with a suprarenal fixation
2020
Abstract Introduction: The treatment of abdominal aortic aneurysm (AAA) is increasingly performed via endovascular aneurysm repair (EVAR). Different types of fixation are possible with EVAR, i.e., below (infrarenal fixation) or above (suprarenal fixation) the renal arteries. Hemodynamic alterations in renal arterial flow with suprarenal (SR) fixation remain to be demonstrated. The IFIXEAR (Impact of Supra-renal Fixation of EVAR on Hemodynamics of Renal Arteries) study is designed to assess the hemodynamic effects at the ostia of at least 1 renal artery, generated immediately post-surgery by the implantation of an aortic stent with SR fixation. Methods: IFIXEAR is a prospective, 2 center stu…
Mortality rates and risk factors for emergent open repair of abdominal aortic aneurysms in the endovascular era
2018
The background of this paper is to report the mortality at 30 and 90 days and at mean follow-up after open abdominal aortic aneurysms (AAA) emergent repair and to identify predictive risk factors for 30- and 90-day mortality. Between 1997 and 2002, 104 patients underwent emergent AAA open surgery. Symptomatic and ruptured AAAs were observed, respectively, in 21 and 79% of cases. Mean patient age was 70 (SD 9.2) years. Mean aneurysm maximal diameter was 7.4 (SD 1.6) cm. Primary endpoints were 30- and 90-day mortality. Significant mortality-related risk factor identification was the secondary endpoint. Open repair trend and its related perioperative mortality with a per-year analysis and a co…
Computed Tomography-Aortography Versus Color-Duplex Ultrasound for Surveillance of Endovascular Abdominal Aortic Aneurysm Repair: A Prospective Multi…
2020
Background Color-duplex ultrasonography (DUS) could be an alternative to computed tomography-aortography (CTA) in the lifelong surveillance of patients after endovascular aneurysm repair (EVAR), but there is currently no level 1 evidence. The aim of this study was to assess the diagnostic accuracy of DUS as an alternative to CTA for the follow-up of post-EVAR patients. Methods Between December 16, 2010, and June 12, 2015, we conducted a prospective, blinded, diagnostic-accuracy study, in 15 French university hospitals where EVAR was commonly performed. Participants were followed up using both DUS and CTA in a mutually blinded setup until the end of the study or until any major aneurysm-rel…
Bicuspid aortic valve and unruptured sinus of Valsalva aneurysm, a rare association
2016
Bicuspid aortic valve (BAV) is one of the most common forms of congenital heart defect and is associated with other congenital vascular and cardiac defects. The most common comorbidity is dilation of thoracic aorta and clinical manifestations are usually related to function of the aortic valve and to other cardiovascular acquired complications. Sinus of Valsalva aneurysm (SVA) is an uncommon congenital cardiovascular anomaly and the combination of these two anomalies is very rare. Common complications are rupture and obstruction of the termination chamber due to space-occupying effect of large unruptured aneurysms. Early cardiac imaging can help limiting morbidity and mortality in these pat…
Patients with bicuspid aortic valve are likely to receive an aortic valve prosthesis during prophylactic resection of their ascending aortic aneurysm.
2015
This study aims to evaluate whether thepresence or discovery of a BAV under ATAA repair would impactthe decision-making of the surgical procedure choice.
Tumor Marker Carbohydrate Antigen 125 Predicts Adverse Outcome After Transcatheter Aortic Valve Implantation
2013
ObjectivesThis study sought to predict the value of tumor marker carbohydrate antigen 125 (CA125) before and after transcatheter aortic valve implantation (TAVI) for all-cause death and a composite endpoint of death, admission for heart failure, myocardial infarction, and stroke (major adverse cardiac events [MACE]).BackgroundRisk stratification after TAVI remains challenging. The use of biomarkers in this setting represents an unmet need.MethodsCA125 was measured in 228 patients before and after TAVI. The association with outcomes was assessed using parametric Cox regression and joint modeling for baseline and longitudinal analyses, respectively. CA125 was evaluated as logarithm transforma…
Anatomical and procedural features associated with aortic root rupture during balloon-expandable transcatheter aortic valve replacement
2013
Background— Aortic root rupture is a major concern with balloon-expandable transcatheter aortic valve replacement (TAVR). We sought to identify predictors of aortic root rupture during balloon-expandable TAVR by using multidetector computed tomography. Methods and Results— Thirty-one consecutive patients who experienced left ventricular outflow tract (LVOT)/annular/aortic contained/noncontained rupture during TAVR were collected from 16 centers. A caliper-matched sample of 31 consecutive patients without annular rupture, who underwent pre-TAVR multidetector computed tomography served as a control group. Multidetector computed tomography assessment included short- and long-axis diameters an…
High incidence of venous thrombosis after surgery for abdominal aortic aneurysm
2009
Objective The incidence of venous thromboembolism (VT) after aortic abdominal aneurysm (AAA) surgery is imprecisely reported. On one hand, thromboprophylaxis has improved, on the other hand, AAA patients have become older and/or present worse comorbidities. Herein, we prospectively analyzed the incidence of VT in a continuous series of patients operated on for AAA repair and looked for predictive factors. Materials and Methods Between January 1, 2005, and December, 31, 2006, 193 consecutive patients (177 men and 16 women), mean age 73 (range, 47-93) underwent elective AAA repair, 137 open (71%) and 56 endovascular (29%), in our institution. Thromboprophylaxis consisted of thigh-length compr…
Renewed endovascular repair for recurrent acute abdominal aortic aneurysm
2008
The aim of the study was to describe the successful endovascular management of a patient who was admitted urgently with a second episode of acute abdominal aortic aneurysm (AAA) 30 months after emergency endovascular abdominal aortic aneurysm repair (eEVAR) for a ruptured AAA. The patient, an 84 year-old male physician, presented with severe acute abdominal and back pain. Contrast-enhanced computer tomography scanning showed type III endoleak owing to complete disconnection of both graft limbs and the prosthetic main body. Treatment consisted of acute stent-grafting with two bridging stent-grafts to seal the endoleak and reline the graft. The patient is alive and well 6 months postoperative…
Editor's Choice – Occurrence and Classification of Proximal Type I Endoleaks After EndoVascular Aneurysm Sealing Using the Nellix™ Device
2017
Objective/Background Proximal type I endoleaks are associated with abdominal aortic aneurysm (AAA) growth and rupture and necessitate repair. The Nellix™ EndoVascular Aneurysm Sealing (EVAS) system is a unique approach to AAA repair, where the appearance and treatment of endoleaks is also different. This study aimed to analyse and categorise proximal endoleaks in an EVAS treated cohort. Methods All patients, treated from February 2013 to December 2015, in 15 experienced EVAS centres, presenting with proximal endoleak were included. Computed tomography scans were analysed by a core laboratory. A consensus meeting was organised to discuss and qualify each case for selection, technical aspects…
