Scattered radiation on cardiologists during interventional cardiac procedure

Publication date: Available online 16 April 2019Source: Radiation Physics and ChemistryAuthor(s): T. Rivera-Montalvo, E.S. Uruchurtu-ChavarínAbstractThe International Commission on Radiological Protection reviewed its recommendation concerning the equivalent dose limit for the dose limits for occupationally exposed persons in a year. This limit was approved and written down in the IAEA (International Atomic Energy Agency) BSS (Basic Safety Standard) of July 2014. For that reason, in this work scattered radiation from fluoroscopy X-ray equipment on eye lens, and whole body dose was determined. For scattered radiation dose determination were used thermoluminescent dosimeter consisted of lithium fluoride doped with magnesium and titanium (LiF:Mg,Ti). 52 interventional cardiology procedures were analyzed and were categorized into two groups depending on the nature of procedure, diagnostic coronary angiography (CA) and percutaneous coronary interventions (PCI). The effective dose on the primary operator (O1) was in the range from 0.97 up to 3.02 μSv in the right side, meanwhile in the left side was in the range from 0.95 up to 12.44 μSv per each procedure. In regard to protection, the associated levels were found higher for one of the cardiologist, corrective action was suggested, ALARA concepts for all cardiologist was recommended for its implementation.

ConclusionsDialysis conduit angiography use has grown substantially, more so than thrombectomy. This growth has been accompanied by a drastic market shift from radiologists in hospitals to nephrologists and surgeons in offices. Despite wide geographic variability nationally, radiologist market share has declined in most states.

Authors: Daida H, Dohi T, Fukushima Y, Ohmura H, Miyauchi K Abstract Enormous effort has been put into the prevention of atherosclerosis through risk modification, especially with lipid-lowering therapies. Regression, that is, the reversal of the atherosclerosis process, has long been a goal of atherosclerosis research among basic and clinical investigators. Intravascular ultrasound (IVUS) was developed in the 1990s as an intracoronary imaging technique to observe the details of the vessel walls and to measure the vessel lumen and plaque area with high reproducibility. Compared with the coronary angiogram, IVUS pro...

Conclusion: Choroideremia is a disease in which the choriocapillaris maintains a normal structure until the loss of the overlying retinal pigment epithelium. The inner retina also appears not to be affected at the vascular level. Although this study is limited by the small number of patients eligible for inclusion in the study, the observations support the concept of targeting gene therapy to the retinal pigment epithelium and outer retina because there is no evidence of independent degeneration of the choriocapillaris.

Purpose: To report optical coherence tomography angiography (OCTA) values in healthy pediatric eyes and to identify factors that may modify these values. Methods: In this prospective observational cross-sectional study, macular OCTA images were acquired from healthy pediatric patients. Main outcome measures were 1) foveal avascular zone (FAZ) area at the level of the superficial retinal capillary plexus (SCP); 2) SCP and deep retinal capillary plexus (DCP) perfusion density (based on the area of vessels); 3) SCP and DCP vessel density (based on a map with vessels of 1-pixel width); and 4) CC perfusion density. Multipl...

Purpose: To understand the relationship between baseline ischemic index (IsI) values on ultra-widefield fluorescein angiography and classification as ischemic central retinal vein occlusion (CRVO). Methods: Single-center retrospective cohort study of CRVO patients imaged using ultra-widefield fluorescein angiography from which IsI values were calculated. An ischemic CRVO was defined as those eyes with an afferent pupillary defect and counting fingers acuity or worse or neovascularization during the first year of follow-up. Logistic regression was performed to characterize the relation between the IsI and clinical outc...

Conclusion: In this study, statistically significant regression in the NVD size and flow area was observed as early as 24 hours after a single intravitreal bevacizumab injection, with a continued decreasing trend for at least a 1-month period.

Implantation of stents in small vessels is often avoided due to the risk of adverse events like stent thrombosis and restenosis. Ultra thin strut drug eluting stents may an option in such cases. A study published in JAMA Cardiology compared ultra thin strut stents with very thin strut stents and previous generation drug eluting stents in small vessel coronary artery disease [1]. It was a pre-specified substudy of the Comparison of Biodegradable Polymer and Durable Polymer Drug-eluting Stents in an All Comers Population (BIO-RESORT) trial. The types of stents used were ultrathin strut sirolimus eluting stents, v...

Conclusion: Eyes with Coats disease in the 1980s demonstrated more advanced findings, often requiring enucleation. Over the decades, greater use of laser photocoagulation and injections has led to improved disease resolution with greater globe salvage.
