Complications of trans-anastomotic externalised stents in open pyeloplasty: influence of the method of placement, the duration of stenting, and the a…
2010
To assess the influence of the method for stent placement, the duration of stenting, and the presence of bladder drainage on the complication rate of open pyeloplasty. Patients and methods: Complications were, retrospectively, compared in 228 consecutive open pyeloplasties performed at institution A using a trans-pyelostomic 6-Fr splint/stent for 5 days and no bladder drainage, and 150 consecutive open pyeloplasties performed at institution B using a trans-nephrostomic 6-Fr splint/stent for 9 days plus bladder drainage. Results: Median age at surgery was comparable between groups. The overall complication rate was 13% and was comparable at the two institutions, but for the presence of perio…
Anomalous origin of all three coronary arteries from right sinus of Valsalva
2016
AbstractCongenital anomalies of the coronary arteries, although uncommon, have the potential to cause serious myocardial damage, ischemic cardiomyopathy, and sudden cardiac death. We report a rare case of origin of all three coronaries from the right sinus of Valsalva.
Implantation of a toric poly(methyl methacrylate) intraocular lens to correct high astigmatism
1999
Abstract A 57-year-old man experienced a decrease in visual function because of cataract formation. Corneal astigmatism was 13.4 diopters (D) because he had had a penetrating keratoplasty 27 years before. Cataract surgery was planned, and biometric data for toric intraocular lens (IOL) implantation were collected for the manufacture of a custom IOL. After phacoemulsification, a toric poly(methyl methacrylate) (PMMA) IOL of +19.0 D spherical and +12.0 D cylindrical power was implanted via a sclerocorneal tunnel incision. Three months postoperatively, corneal astigmatism was 14.3 D and best corrected visual acuity (BCVA), 20/25. Postoperative refraction (+1.5 −3.0 × 90) and BCVA remained stab…
Combining Sirolimus-eluting Stents and External Irradiation in Cholesterol-fed Rabbits Increased Incomplete Stent Apposition and Decreased Re-endothe…
2009
Restenosis after the implantation of a drug-eluting stent or after vascular irradiation therapy shares similar physiopathological mechanisms. No experimental data are currently available on vascular wall behavior after external irradiation on arteries stented with sirolimus-eluting stents (SES). Ten New Zealand white rabbits received a 0.5% cholesterol-enriched chow for 1 month. Bilateral iliac artery stent implantation was then performed with an SES (Cypher; Cordis Corp). The animals were randomized into either an irradiated group (I, 2 Gy external x-ray irradiation, n = 5) or a control group (C, n = 5). The cholesterol-enriched chow was continued for 1 additional month after stent implant…
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 …
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…
Mild phenotypes in a series of patients with Opitz GBBB syndrome with MID1 mutations
2004
Contains fulltext : 48815.pdf (Publisher’s version ) (Closed access) Opitz syndrome (OS; MIM 145410 and MIM 300000) is a congenital midline malformation syndrome characterized by hypertelorism, hypospadias, cleft lip/palate, laryngotracheoesophageal (LTE) abnormalities, imperforate anus, developmental delay, and cardiac defects. The X-linked form (XLOS) is caused by mutations in the MID1 gene, which encodes a microtubule-associated RBCC protein. In this study, phenotypic manifestations of patients with and without MID1 mutations were compared to determine genotype-phenotype correlations. We detected 10 novel mutations, 5 in familial cases, 2 in sporadic cases, and 3 in families for whom it …
Efficacy of systemic administration of riboflavin on a rabbit model of corneal alkali burn
2020
AbstractChanges in the barrier mechanisms in the eye should determine the rational route for the administration and dosage of each drug in the treatment of traumatic injuries and other pathologies. The aim of this study was to examine the efficacy of intra-arterial delivery of 14C-riboflavin (as an “indicator”) and compare it with intravenous and intramuscular administration in an animal model of chemical eye burn. 14C-riboflavin (14C-I) was administered by intra-arterial (carotid artery), intravenous (femoral vein) and intramuscular (femoral muscle) routes. The total radioactivity was determined over 2 h in the plasma and structures of the rabbit’s eyes using a scintillation counter. The r…
Depiction of anomalous coronary vessels and their relation to the great arteries by magnetic resonance angiography
2000
Three-dimensional respiratory-gated coronary MR angiography (MRA) allowed accurate analysis of the anatomy of the coronary arteries and their relation to the adjacent anatomic structures in two patients with anomalous origin and proximal course of the coronary vessels. Together with functional tests, it decisively influenced further therapy.
Usefulness of multislice computed tomography to assess patency of coronary artery stents versus conventional coronary angiography
2008
BACKGROUND: The aim of the present study was to assess the in-stent restenosis and occlusion of coronary artery stents by multislice computed tomography (MSCT) compared with conventional coronary angiography in patients with atypical chest pain and not practicable/non-conclusive stress test. METHODS: Between December 2004 and March 2006, 81 patients were scheduled and of these 72 (65 men, mean age 61 years) with 90 stents underwent MSCT angiography using a 16-slice scanner, Toshiba Aquilion 16, 8-12 months after stent placement. RESULTS: Of the 90 stents, 71 (79%) could be assessed and 19 (21%) were excluded because the image quality at the stent level was incompatible with diagnostic asses…
