Vena cava resection and bypass for recurrent cervical cancer

2021

A 42-year-old woman was diagnosed with a second para-aortic cervical cancer. The patient had undergone a radical hysterectomy with pelvic lymphadenectomy for FIGO stage IB1 squamous cervical cancer 3 years prior to current presentation. No adjuvant treatment was performed after the primary surgery

The Transversus and Rectus Abdominis Musculoperitoneal (TRAMP) Composite Flap for Vulvovaginal Reconstruction

1996

The transversus and rectus abdominis musculoperitoneal (TRAMP) flap, a novel composite flap supplied by the deep inferior epigastric vessels, was used successfully for partial vulvovaginal reconstruction following anterior and posterior exenteration. The full potential of the TRAMP flap in vulvovaginal reconstruction is being investigated further.

Incidence of Acute Ischemic Stroke With Visible Arterial Occlusion

2020

Background and Purpose: Because of several methodological limitations, previous studies focusing on the prevalence of large vessel occlusion in ischemic stroke (IS) patients provided conflicting results. We evaluated the incidence of IS with a visible arterial occlusion using a comprehensive population-based registry. Methods: Patients with acute IS were prospectively identified among residents of Dijon, France, using a population-based registry (2013–2017). All arterial imaging exams were reviewed to assess arterial occlusion. Annual incidence rates of IS (first-ever and recurrent events) and IS with a visible occlusion were calculated. Results: One thousand sixty cases of IS were recorde…

Role of Cachexia and Fragility in the Patient Candidate for Cardiac Surgery

2021

Frailty is the major expression of accelerated aging and describes a decreased resistance to stressors, and consequently an increased vulnerability to additional diseases in elderly people. The vascular aging related to frail phenotype reflects the high susceptibility for cardiovascular diseases and negative postoperative outcomes after cardiac surgery. Sarcopenia can be considered a biological substrate of physical frailty. Malnutrition and physical inactivity play a key role in the pathogenesis of sarcopenia. We searched on Medline (PubMed) and Scopus for relevant literature published over the last 10 years and analyzed the strong correlation between frailty, sarcopenia and cardiovascular…

Reduced In Vivo Aortic Uptake of Radiolabeled Oxidation-Specific Antibodies Reflects Changes in Plaque Composition Consistent With Plaque Stabilizati…

2004

Objective— Labeled oxidation-specific antibodies (Ox-AB) detect, quantify, and noninvasively image lipid-rich atherosclerotic lesions. However, it is unknown whether Ox-AB detect plaque stabilization. Methods and Results— The aortic uptake of intravenously injected 125 I-MDA2 (Ox-AB to malondialdehyde [MDA]–low-density lipoprotein [LDL]) was quantitated in: (1) LDL receptor−/− mice with established atherosclerosis continued on Western diet (Progression) or switched to chow (Regression) or chow+vitamins E and C (Regression-VIT) for 6 months; and (2) Watanabe rabbits (3- to 57-months old) with naturally evolved atherosclerotic lesions. In mice, the Progression group had more extensive athero…

Rapid vascularization of starchâ poly(caprolactone) in vivo by outgrowth endothelial cells in co-culture with primary osteoblasts

2011

The successful integration of in vitro-generated tissues is dependent on adequate vascularization in vivo. Human outgrowth endothelial cells (OECs) isolated from the mononuclear cell fraction of peripheral blood represent a potent population of circulating endothelial progenitors that could provide a cell source for rapid anastomosis and scaffold vascularization. Our previous work with these cells in co-culture with primary human osteoblasts has demonstrated their potential to form perfused vascular structures within a starch–poly(caprolactone) biomaterial in vivo. In the present study, we demonstrate the ability of OECs to form perfused vascular structures as early as 48 h following subcut…

Kontrastverstärkte MR-Angiographie abdomineller Gefäßean einem 1.0 T-System*

2000

Purpose To evaluate the efficacy of breath-hold, three-dimensional, contrast-enhanced magnetic resonance angiography with a 1.0 T system for imaging the abdominal vessels in comparison to conventional arteriography (CA). Methods The abdominal aorta and visceral arteries were studied in 54 patients (60 examinations) on a 1.0 T scanner using an ultrafast gadolinium-enhanced gradient-echo sequence with the following parameters: TR/TE = 3.8/1.4 ms, flip angel 25 degrees, matrix 198 x 256, field 380-420 mm, pixel size 1.9 x 1.48 mm2, slice thickness 1.5-2.5 mm, acquisition time 22-26 sec. Individual circulation times were determined by a test bolus before each MR angiography. Conventional arteri…

CardioPulse: developments in the treatment of aortic aneurysms in 2014

2015

Since the introduction of EndoVascular Aortic Repair (EVAR) for the treatment of abdominal aortic aneurysms (AAA) more than 20 years ago, the technique has evolved rapidly, from tubular grafts for fairly simple abdominal aortic anatomy, to bifurcated, fenestrated, branched, or parallel grafts for complex aortic aneurysms, no longer confined to the infrarenal abdominal aorta.

Early results of a low-profile stent-graft for thoracic endovascular aortic repair

2020

Purpose To assess outcomes of a low-profile thoracic stent-graft in the treatment of thoracic aortic pathologies. Methods A retrospective analysis of all consecutive patients with aortic thoracic pathologies treated with the RelayPro device in two university hospitals between October 2018 and July 2019. Results 23 patients (65% men; mean age 63.4 ± 15 years) were treated. Pathologies included aortic dissections (n = 10), 5 residual type A (22%) and 5 type B (22%), 6 degenerative aortic aneurysms (26%), 4 penetrating aortic ulcers (17%), and aortic erosion, intramural hematoma and aortic rupture (n = 1 and 4% in each case). Two cases (9%) were emergent and two urgent. Proximal landing was a…
