Procedural, Functional and Prognostic Outcomes Following Recanalization of Coronary Chronic Total Occlusions. Results of the Iberian Registry.

2019

Introduction and objectives: There is current controversy regarding the benefits of percutaneous recanalization (PCI) of chronic total coronary occlusions (CTO). Our aim was to determine acute and follow-up outcomes in our setting. Methods: Two-year prospective registry of consecutive patients undergoing PCI of CTO in 24 centers. Results: A total of 1000 PCIs of CTO were performed in 952 patients. Most were symptomatic (81.5%), with chronic ischemic heart disease (59.2%). Previous recanalization attempts had been made in 15%. The mean SYNTAX score was 19.5 +/- 10.6 and J-score was > 2 in 17.3%. A retrograde procedure was performed in 92 patients (9.2%). The success rate was 74.9% and was hi…

Freestyle-Like V-Y Flaps of the Eyebrow: A New Outlook and Indication of an Historical Technique

2013

The eyebrow region is of utmost importance for facial movement, symmetry, and the overall cosmetic appearance of the face. Trauma or tumor resection often leave scars that may dislocate the eyebrow producing an alteration both in static symmetry of the face and in the dynamic expressivity. The authors present a technique for eyebrow’s defects repair using the remaining eyebrow advancement by means of a “freestyle-like” V-Y flap. In the past two years a total of eight consecutive patients underwent excision of skin lesions in the superciliary region and immediate reconstruction with this technique. On histology, six patients were affected from basal cell carcinomas, one from squamous cell ca…

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…

The recurrence of odontogenic keratocysts in pediatric patients is associated with clinical findings of Gorlin-Goltz Syndrome

2019

Background Odontogenic keratocyst (OKC) is an odontogenic developmental cyst that presents distinct clinical behavior. This lesion has been described as dental cysts with keratinization since the 1930s, however the term "OKC" was established in 1956. This study aims to determine the frequency and features of OKC in children aged 0 to 14 years in an oral pathology service in Brazil. Material and Methods A retrospective study was performed to review cases of OKC in children diagnosed between 1986 and 2017. Clinical data were evaluated from medical records (gender, race, age, anatomical location, treatment, radiographic findings and follow-up). Results Ninety-seven cases of OKC were diagnosed …

Odontoid process and clival regeneration with Chiari malformation worsening after transoral decompression: an unexpected and previously unreported ca…

2015

Purpose: Transoral odontoidectomy followed by occipito-cervical fixation is a widely used approach to relieve ventral compressions at the craniovertebral junction (CVJ). Despite the large amount of literature on this approach and its complications, no previous reports of odontoid process and clival regeneration following transoral odontoidectomy are present in the English literature. Methods: We report the case of odontoid process and clival regeneration following transoral odontoidectomy. Results: A 7-year-old boy presented with symptoms of brainstem and upper cervical spinal cord compression due to a complex malformation at the CVJ including a basilar invagination with Chiari malformation…

Cyberknife radiosurgery for cranial plasma cell tumor

2014

Cranial and intracranial involvement by myelomatous disease is relatively uncommon. Furthermore, systemic manifestations of multiple myeloma are present in the majority of these cases at the time of symptom onset. The authors report the case of a patient with serial appearance of multiple intracranial plasma cell tumor localizations as the first manifestations of a multiple myeloma. The patient was treated with CyberKnife radiosurgery for a lesion localized at the clivus and sella turcica with complete local control. With such a technique, based on high-dose conformality, the tumor was centered with an ablative dose of radiation and, at the same time, with a low dose spreading to the surrou…

A New Model of Skull Base Reconstruction following Expanded Endonasal or Transoral Approaches – Long-Term Results in Primates

2007

<i>Objective:</i> The direct endonasal or transoral transclival approaches to the skull base permit effective minimally invasive surgery along the clivus region. Developing consistently effective techniques to prevent cerebrospinal fluid (CSF) leaks and their consequences (infections and healing processes with long and complicated recoveries) remains a major challenge. In this study, we tested over a long period a method of bone reconstruction newly developed by us, which makes use of a specially designed elastic silicone plug that can be employed for bone replacement after minimally invasive skull base surgery without risk of postoperative CSF leaks. After acute testing of plug…

Oculoectodermal syndrome: Report of a new case with a broad clinical spectrum

2014

Oculoectodermal syndrome (OMIM 600268) is rare and characterized by aplasia cutis congenita, epibulbar dermoids, and other abnormalities. We report herein on a newly recognized patient with oculoectodermal syndrome, which is the 19th reported patient with OES. The boy aged six years demonstrated a broad clinical spectrum of this condition, including aplasia cutis congenita, epibulbar dermoids, hyperkeratotic papule, mildly enlarged cisterna magna, and an enlarged fluid space in the quadrigeminal cistern, suggesting a cyst. He also manifested anomalies not reported associated with this disorder, including systematized epidermal nevus following Blaschko's lines, hypopigmented skin lesions, an…

Chromatic-achromatic perimetry in four clinic cases: Glaucoma and diabetes

2015

Color perimetry has interesting clinical application for the diagnosis and detection of certain eye conditions, due to the variations that certain diseases can cause in chromatic thresholds, both in the red-green (RG) and the blue-yellow (BY) pathways.[1,2,3,4] The separate study of the visual function of both the chromatic and achromatic mechanisms could be more efficient in detecting sensitivity variations, and such variations would not be obscured by the intrusion of other mechanisms. Currently, the supply of conventional perimeters that are capable of performing a chromatic perimetry test is very limited and with reduced options regarding the possibility of choosing the physical charact…
