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…

Kawasaki disease triggered by parvovirus infection: an atypical case report of two siblings.

2019

Abstract Background There are reports of the familial occurrence of Kawasaki disease but only a few reports described Kawasaki disease in siblings. However, the familial cases were not simultaneous. In these patients the idea of infective agents as trigger must be considered. Case presentation We describe two siblings with atypical presentations of Kawasaki disease; the sister was first diagnosed as having parvovirus infection with anemia and the brother was diagnosed as having myocarditis. The first patient was a 9-month-old Caucasian girl with fever, conjunctivitis, rash, and pharyngitis, and later she had cervical adenopathy, diarrhea and vomiting, leukocytosis, and anemia, which were ex…

Less invasive (common) femoral artery aneurysm repair using endografts and limited dissection

2013

Objective We report our experience with the treatment of femoral artery aneurysms (FAAs) under local anaesthesia with limited dissection, using endografts to facilitate the proximal anastomosis and some distal anastomoses. Method Between January 2006 and December 2010, six males, mean age 72 years (range, 65–80 years) with FAAs were treated at the University Hospital of Zurich. All operations were performed under local anaesthesia with analgosedation, except for one performed under spinal anaesthesia. After limited dissection and puncture of the anterior wall of the FAA, a sheath and a self-expanding endograft were introduced over a guide wire and with fluoroscopy they were guided intralumi…

Detection of a Dissecting Aortic Aneurysm by Renal Transplant Imaging

1997

After 2 years with a normal post-transplant course a 45-year-old man showed an elevated creatinine level (4.5 mg/dL). Transplantation had been neccessary because of progressive glomerulonephritis. Renal transplant imaging was obtained with 150 Mbq Tc-99m MAG3. The perfusion images showed radionuclide accumulation in the area of the upper abdominal aorta and delayed perfusion of the right iliac artery. Accumulation of Tc-99m MAG3 in the transplant was slow and no filling of the bladder could be observed. Immediately after imaging, the patient developed acute hemorrhagic shock. At emergency surgery, a long dissecting and ruptured aneurysm of the abdominal aorta was seen causing delayed and re…

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.

This study aims to evaluate whether thepresence or discovery of a BAV under ATAA repair would impactthe decision-making of the surgical procedure choice.
