Influence of occlusal loading on peri-implant clinical parameters. A pilot study
2013
Objectives: To investigate the relation between occlusal loading and peri-implant clinical parameters (probing depth, bleeding on probing, gingival retraction, width of keratinized mucosa, and crevicular fluid volume) in pa - tients with implant-supported complete fixed prostheses in both arches. Material and Methods: This clinical study took place at the University of Valencia (Spain) dental clinic. It included patients attending the clinic for regular check-ups during at least 12 months after rehabilitation of both arches with implant-supported complete fixed ceramo-metallic prostheses. One study implant and one control implant were established for each patient using the T-Scan®III comput…
Straight and tilted implants for supporting screw-retained full-arch dental prostheses in atrophic maxillae : a 2-year prospective study
2018
Background To evaluate, over a 2-year period, the treatment outcomes for maxillary full-arch fixed dental prostheses (FDPs) supported by a combination of both tilted and axially-placed implants and to compare the marginal bone loss (MBL) and implant survival rates (SR) between tilted and axial implants. Material and Methods A retrospective study has been carried out. Thirty-two patients (16 males and 16 females) treated with maxillary full-arch FDPs were included in this retrospective study. A total of 187 implants were inserted to rehabilitate the fully edentulous maxillary arches: 36% of them were tilted (T group, n = 68) and the remaining 64% were axially placed (A group, n = 119). From …
Peroperative Intravascular Ultrasound for Endovascular Aneurysm Repair versus Peroperative Angiography: A Pilot Study in Fit Patients with Favorable …
2020
The aim of this study was to compare intravascular ultrasound (IVUS) assistance for endovascular aortic aneurysm repair (EVAR) to standard assistance by angiography.From June 2015 to June 2017, 173 consecutive patients underwent EVAR. In this group, 69 procedures were IVUS-assisted with X-ray exposure limited to completion angiography for safety purposes because an IVUS probe does not yet incorporate a duplex probe (group A), and 104 were angiography-assisted procedures (group B). All IVUS-assisted procedures were performed by vascular surgeons with basic duplex ultrasound (DUS) training. The primary study endpoints were mean radiation dose, duration of fluoroscopy, amount of contrast media…
Anastomotic Pseudoaneurysm Complicating Renal Transplantation: Treatment Options
2010
Introduction: Anastomotic pseudoaneurysm following renal transplantation is uncommon. Indications for repair, treatment options and outcomes remain controversial. Report: We present 6 renal transplant recipients with large anastomotic pseudoaneurysms. Five of the patients underwent open repair while one had a stent-grafting and delayed transplant nephrectomy for a ruptured pseudoaneurysm. A transplant nephrectomy was needed in all cases but one. Arterial reconstruction enabled limb salvage in all cases. One patient died of sepsis postoperatively. No patient presented late infection, failure of vascular reconstruction, nor pseudoaneurysm recurrence. Conclusions: Surgical excision of anastomo…
Time interval between infective endocarditis first symptoms and diagnosis: relationship to infective endocarditis characteristics, microorganisms and…
2016
International audience; OBJECTIVE: To analyze the characteristics and outcome of infective endocarditis (IE) according to the time interval between IE first symptoms and diagnosis.METHODS: Among the IE cases of a French population-based epidemiological survey, patients having early-diagnosed IE (diagnosis of IE within 1 month of first symptoms) were compared with those having late-diagnosed IE (diagnosis of IE more than 1 month after first symptoms).RESULTS: Among the 486 definite-IE, 124 (25%) had late-diagnosed IE whereas others had early-diagnosed IE. Early-diagnosed IE were independently associated with female gender (OR = 1.8; 95% CI [1.0-3.0]), prosthetic valve (OR= 2.6; 95% CI [1.4-5…
Collected Transatlantic Experience From the PERICLES Registry: Use of Chimney Grafts to Treat Post-EVAR Type Ia Endoleaks Shows Good Midterm Results
2018
Purpose: The aim of this retrospective analysis was to evaluate the performance of the chimney (ch) technique in the treatment of type Ia endoleaks after standard endovascular aneurysm repair (EVAR). Methods: Between January 2008 and December 2014, 517 chEVAR procedures were performed in 13 US and European vascular centers (PERICLES registry). Thirty-nine patients (mean age 76.9±7.1 years; 33 men) were treated for persistent type Ia endoleak and had computed tomography angiography or magnetic resonance angiography follow-up at >1 month. Endurant abdominal stent-grafts were used in the 20 cases. Single chimney graft placement was performed in 18 (46%) patients and multiple in 21 (54%). O…
Single-centre experience and preliminary Results of intravascular ultrasound in endovascular aneurysm repair
2019
Background Intravascular ultrasound (IVUS) has been introduced as diagnostic adjunct to provide new insights into the diagnosis and therapy of vascular disease. Herein, we compared the outcomes of conventional endovascular aneurysm repair (EVAR) and EVAR with IVUS in patients presenting with infrarenal abdominal aortic aneurysm using a propensity-matched cohort. Methods From May 2013 to August 2017, 221 patients were retrospectively analyzed. Of that, 122 patients were eligible for inclusion and underwent propensity score matching. Perioperative mortality and morbidity, renal function impairment, endoleak incidence, mean contrast medium usage, operative time, radiation exposure (including f…
Fenestrated Stent Grafting for Short-necked and Juxtarenal Abdominal Aortic Aneurysm
2010
Objectives: To present an 8-year clinical experience in the endovascular treatment of short-necked and juxtarenal abdominal aortic aneurysm (AAA) with fenestrated stent grafts. Methods: At our tertiary referral centre, all patients treated with fenestrated and branched stent grafts have been enrolled in an investigational device protocol database. Patients with short-necked or juxtarenal AAA managed with fenestrated endovascular aneurysm repair (F-EVAR) between November 2001 and April 2009 were retrospectively reviewed. Patients treated at other hospitals under the supervision of the main author were excluded from the study. Patients treated for suprarenal or thoraco-abdominal aneurysms wer…
Results of chimney endovascular aneurysm repair as used in the PERICLES Registry to treat patients with suprarenal aortic pathologies
2020
Background: The prevailing evidence calls for using chimney/snorkel endovascular repair (ch-EVAR) with one or two chimney grafts. No studies up to now focus on its applicability and results for the treatment of suprarenal aortic pathologies (SRAP). Hence, we evaluated the clinical and radiologic results of ch-EVAR treatment for SRAP placing three or more chimney grafts within the PERICLES Registry. Methods: Data from 517 patients suffering complex aortic pathologies treated by ch-EVAR between 2008 and 2014 at 13 European and U.S. centers were retrospectively reviewed and analyzed. Results: Sixty-seven ch-EVAR-treated patients (12.9% of the entire PERICLES cohort) presented SRAP (83.5% elect…
Sequential Femorodistal Composite Bypass with Second Generation Glutaraldehyde Stabilized Human Umbilical Vein (HUV)
2005
Abstract Objective To evaluate the performance of sequential composite bypasses with second generation glutaraldehyde stabilized human umbilical vein (HUV) and autologous vein. Design Retrospective study of consecutive patients, in a single centre. Patients From January 1998 to December 2003, 54 femoro-distal HUV-autologous vein sequential composite bypasses were constructed in 52 patients with critical leg ischemia and absence of sufficient length of autologous vein. Methods All infra-inguinal bypass operations were registered in a computerized database and prospectively followed. Bypasses using sequential HUV-composite technique were reviewed for graft patency, limb salvage and patient su…
