Long-term follow-up of children with surgically treated vesicorenal reflux: postoperative incidence of urinary tract infections, renal scars and arte…

1989

With a mean follow-up of 10.8 years, 160 female and 29 male patients were investigated after successful correction of vesicoureterorenal reflux. All patients suffered from urinary tract infection (UTI) preoperatively, while postoperatively 42% of the patients developed further UTIs but with a significantly diminished rate of febrile infections. In comparison to a group of patients without postoperative UTI (n = 16), the uroepithelial cells of those patients with a high infection rate after reflux correction showed a significantly lower bacterial growth suppression (n = 37). Renal scars were found in 22% of the investigated renal units with operated ureters (n = 211). Of the preoperatively u…

Optical Coherence Tomography Versus Intravascular Ultrasound to Evaluate Coronary Artery Disease and Percutaneous Coronary Intervention

2013

ObjectivesWe compared intravascular ultrasound (IVUS) and 2 different generations of optical coherence tomography (OCT)—time-domain OCT (TD-OCT) and frequency-domain OCT (FD-OCT)—for the assessment of coronary disease and percutaneous coronary intervention (PCI) using stents.BackgroundOCT is a promising light-based intravascular imaging modality with higher resolution than IVUS. However, the paucity of data on OCT image quantification has limited its application in clinical practice.MethodsA total of 227 matched OCT and IVUS pull backs were studied. One hundred FD-OCT and IVUS pull backs in nonstented (n = 56) and stented (n = 44) vessels were compared. Additionally, 127 matched TD-OCT and …

Initial Clinical Experience Using the Low-Profile Altura Endograft System With Double D-Shaped Proximal Stents for Endovascular Aneurysm Repair.

2018

Purpose: To report the initial clinical results of endovascular aneurysm repair (EVAR) using the low-profile (14-F) Altura Endograft System, which features a double “D-shaped” stent design with suprarenal fixation and modular iliac components that are deployed from distal to proximal. Methods: From 2011 to 2015, 90 patients (mean age 72.8±8.3 years; 79 men) with abdominal aortic aneurysm (AAA; mean diameter 53.8±5.7 mm) were treated at 10 clinical sites in 2 prospective, controlled clinical studies using the Altura endograft. Outcomes evaluated included mortality, major adverse events (MAEs: all-cause death, stroke, paraplegia, myocardial infarction, respiratory failure, bowel ischemia, an…

CT Angiography at 24 Months Demonstrates Durability of EVAR With the Use of Chimney Grafts for Pararenal Aortic Pathologies

2013

PURPOSE: To present the 24-month radiological follow-up data for patients with pararenal aortic pathologies treated with chimney and periscope grafts during endovascular repair. METHODS: Between January 2008 and December 2011, 124 high-risk patients with complex pararenal aortic pathologies were treated using the chimney technique at 2 European vascular and cardiovascular centers with advanced experience of the described technique. In particular, 50 patients were treated at Site 1 and 74 at Site 2. Forty (32.2%) patients (32 men; mean age 79.2±4.9 years) completed computed tomographic angiography follow-up at 24 months postoperatively. RESULTS: The overall technical success was 100%, and th…

The Gore Hybrid Vascular Graft in renovisceral debranching for complex aortic aneurysm repair.

2016

Objective This study reports our initial experience with the Gore Hybrid Vascular Graft (GHVG; W. L. Gore & Associates, Flagstaff, Ariz) for staged hybrid open renovisceral debranching and endovascular aneurysm repair in patients affected by thoracoabdominal aortic aneurysms and pararenal abdominal aortic aneurysms (PAAAs). Methods Between December 2012 and December 2013, we analyzed outcomes of 13 patients who underwent open surgical debranching of renovisceral vessels for thoracoabdominal aortic aneurysm and PAAAs. All patients were considered at high risk for conventional surgery. Inclusion criterion was treatment by open surgical debranching of at least one visceral artery (renal artery…

Comparison of Ivabradine Versus Metoprolol in Early Phases of Reperfused Anterior Myocardial Infarction With Impaired Left Ventricular Function: Prel…

2009

BACKGROUND: beta-blockers in ST-segment elevation myocardial infarction (STEMI) are indicated for patients without a contraindication, particularly in patients with high heart rates (HR) or blood pressures. Epidemiological studies have shown that elevated HR represents a risk factor for cardiovascular morbidity. The study investigates the feasibility, tolerability, and the effects after 30 days of follow-up of ivabradine (IVA) versus metoprolol (METO) in early phases of anterior STEMI reperfused by percutaneous coronary intervention (PCI). METHODS AND RESULTS: Patients with a first anterior STEMI, Killip class I-II, an acceptable echocardiographic window, and admitted within 4hours of the o…

Feasibility of Implanting 50-60 mm-Tapered Drug Eluting Stents in Chronic Total Occlusions.

2018

Abstract Background Percutaneous coronary intervention (PCI) of chronic total occlusions (CTO) usually involves multiple overlapping stents implantation to cover long coronary segments. A higher rate of restenosis has been described with stent overlapping. Recently, new long tapered stents emerged as a potential tool for treating long coronary lesions. Feasibility of using these new devices for the CTO PCI has not been described. The aim of this work was to describe our initial experience with 50 and 60 mm-long tapered sirolimus-eluting stents (SES) in CTO PCI. Methods We included 54 consecutive patients who underwent a CTO PCI and in whom an attempt to implant a 50 or 60 mm-long tapered SE…

Radiolucent Carbon Fiber–Reinforced Pedicle Screws for Treatment of Spinal Tumors: Advantages for Radiation Planning and Follow-Up Imaging

2016

Objective Surgical treatment of spinal tumors regularly includes spinal instrumentation with pedicle screws. Most modern pedicle screws are made of titanium alloy, which is associated with artifacts on postoperative imaging such as computed tomography and/or magnetic resonance imaging. These artifacts hamper radiation treatment planning and execution and follow-up imaging. Recently, carbon fiber–reinforced polyetheretherketone (CFRP) implants became available for posterior instrumentation with the aim to reduce imaging artifacts by implants. Methods Patients harboring spinal tumors underwent posterior stabilization using CFRP pedicle screws. Postoperative imaging was evaluated for implant a…

Failed hypospadias in paediatric patients

2013

Failed hypospadias refers to any hypospadias repair that leads to complications or causes patient dissatisfaction. The complication rate after hypospadias repairs ranges from 5-70%, but the actual incidence of failed hypospadias is unknown as complications can become apparent many years after surgery and series with lifelong follow-up data do not exist. Moreover, little is known about uncomplicated repairs that fail in terms of patient satisfaction. Risk factors for complications include factors related to the hypospadias (severity of the condition and characteristics of the urethral plate), the patient (age at surgery, endocrine environment, and wound healing impairment), the surgeon (tech…

Lingual mucosal grafts for anterior urethroplasty: a review

2009

We critically reviewed recent reports of lingual mucosal grafts (LMGs) for substitution urethroplasty, to determine the efficacy and complications of this approach. Only a few centres have published the short or interim outcome of LMG urethroplasty. These studies dealt mainly with surgical techniques and harvesting LMGs, emphasizing the comparison of different intra-oral donor sites. The preliminary results seem to be encouraging for the safety and efficacy of LMG urethroplasty. When compared with other substitute materials, LMG give equally good results with much easier harvesting and minimal donor site morbidity. Thus, lingual mucosa is most likely to become an alternative to oral mucosa …
