Visual and optical performance with the ReZoom multifocal intraocular lens
2011
Purpose This study evaluated visual acuity, contrast sensitivity, and wavefront aberrations after refractive multifocal intraocular lens (IOL) implantation. Methods A prospective study comprising 174 eyes of 87 patients who had bilateral implantation of a multifocal IOL was carried out. A control group of 100 eyes of 50 age-matched patients with a monofocal IOL was used for comparison. Uncorrected and corrected distance and near visual acuity, contrast sensitivity (CS), and wavefront analysis (Hartmann-Shack) was performed 6 months after surgery. Contrast sensitivity was tested for distance and near under mesopic (2 cd/m2) and photopic conditions (90 cd/m2). Results Distance photopic CS was…
ICD Implantation in infants and small children: the extracardiac technique.
2007
There is no clear methodology for implantation of an internal cardioverter-defibrillator (ICD) in infants and small children. The aim of this study was to assess efficacy and safety of an extracardiac ICD implantation technique in pediatric patients.An extracardiac ICD system was implanted in eight patients (age: 0.3-8 years; body weight: 4-29 kg). Under fluoroscopic guidance a defibrillator lead was tunneled subcutaneously starting from the anterior axillar line along the course of the 6th rib until almost reaching the vertebral column. After a partial inferior sternotomy, bipolar steroid-eluting sensing and pacing leads were sutured to the atrial wall (n = 2) and to the anterior wall of t…
Prospective visual evaluation of apodized diffractive intraocular lenses
2006
To evaluate distance, intermediate, and near visual performance in patients who had multifocal apodized diffractive intraocular lens (IOL) implantation.Fernández-Vega Ophthalmological Institute, Oviedo, Spain.The best corrected distance visual acuity, best distance-corrected near visual acuity, intermediate visual acuity, distance contrast sensitivity under photopic and mesopic conditions, and patient satisfaction were measured in 325 patients and 335 patients who had bilateral implantation of the model SA60D3 IOL (AcrySof ReSTOR, Alcon) and model SN60D3 IOL (AcrySof Natural ReSTOR), respectively.At the 6-month postoperative visit, binocular best corrected distance acuity with the ReSTOR IO…
Clear Lens Extraction with Multifocal Apodized Diffractive Intraocular Lens Implantation
2007
Purpose To assess efficacy, safety, predictability, and stability after clear lens extraction (CLE) with multifocal diffractive intraocular lens (IOL) implantation. Design Prospective, nonrandomized, masked observational case series (self-controlled). Participants Two hundred twenty-four eyes of 112 consecutive patients after CLE with bilateral AcrySof ReSTOR Natural IOL implantation. Eyes were divided into myopic (mean spherical equivalent [SE], −6.01±2.71 diopters [D]) and hyperopic (mean SE, +3.86±2.52 D) groups. Methods Monocular and binocular uncorrected distance visual acuity (VA), best-corrected distance VA, uncorrected distance near VA, and best distance-corrected near VA were recor…
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…
Cinical outcomes of Endurant II stent-graft for infrarenal aortic aneurysm repair: comparison of on-label versus off-label use.
2016
Purpose We aimed to compare the outcomes of the Endurant II (Medtronic) stent-graft used under instructions for use versus off-label in high-risk patients considered unfit for conventional surgery. Methods Data from patients treated with the Endurant II stent-graft between December 2012 and March 2015 were retrospectively analyzed. Sixty-four patients were included. Patients were assigned to group A if treated under instructions for use (n=34, 53%) and to group B if treated off-label (n=30, 47%). Outcome measures included perioperative mortality and morbidity, survival, freedom from reintervention, endoleak incidence, in-hospital length of stay, and mean stent-graft component used. Mean fol…
A 12-Year Experience With Chimney and Periscope Grafts for Treatment of Type I Endoleaks.
2015
Purpose: To evaluate the midterm outcomes of chimney and/or periscope grafts (CPGs) in patients presenting type I endoleak after a previous endovascular aneurysm repair (EVAR). Methods: Between June 2002 and April 2014, 24 consecutive patients (mean age 73.9±9.2 years; 23 men) presenting a type I endoleak were addressed with CPGs to extend the proximal and/or distal landing zone and to maintain side branch perfusion. Indication for treatment was a type Ia endoleak in 23 (96%) patients and a type Ib endoleak in one. Median interval from the previous EVAR to endoleak treatment with CPGs was 52.2±48.9 months (range 0.2–179). All patients had proximal/distal landing zones precluding any standa…
Secondary aortoduodenal fistula.
2008
Aorto-duodenal fistulae (ADF) are the most frequent aorto-enteric fistulae (80%), presenting with upper gastrointestinal bleeding. We report the first case of a man with a secondary aorto-duodenal fistula presenting with a history of persistent occlusive syndrome. A 59-year old man who underwent an aortic-bi-femoral bypass 5 years ago, presented with dyspepsia and biliary vomiting. Computed tomography scan showed in the third duodenal segment the presence of inflammatory tissue with air bubbles between the duodenum and prosthesis, adherent to the duodenum. The patient was submitted to surgery, during which the prosthesis was detached from the duodenum, the intestine failed to close and a ga…
Gerbode-type left ventricular outflow tract to right atrial fistula complicating prosthetic aortic valve replacement identified by cardiac computed t…
2012
Abstract Acquired left ventricular-right atrial communication ( Gerbode-type defect) is a rare complication of infective endocarditis. Although transesophageal echocardiography remains the technique of choice for the evaluation of complications of endocarditis this case highlights the usefulness of cardiac computed tomography in this scenario, particularly in cases where assessment of coronary anatomy is required before surgery.
Post laryngectomy speech rehabilitation outcome in elderly patients
2013
The aim of our work has been to evaluate the different options of tracheoesophageal voice rehabilitation in over 70-year-old patients, who had undergone laryngectomy, assessing advantages and drawbacks of this method of vocal recovery. A retrospective study has been carried out. This has included 40 subjects, all aged more than 70 years old, who have been referred to tracheoesophageal voice rehabilitation. It has been realized a phonatory fistula between trachea and esophagus with prosthesis positioning by means of a primary puncture in 18 cases and it has been realized a secondary puncture in 22 cases. The results gathered in these patients were compared with data obtained from a group mad…
