Background: The purpose of this study was to determine the effectiveness of a side shield radiation protection method designed to decrease the scatter radiation exposure experienced by operators during cardiac catheterization procedures. Methods and Results: The study included 50 patients undergoing diagnostic cardiac catheterization. Scatter radiation exposure was measured directly with silicone diode dosimeters. Radiation doses were measured outside of protective lead draping worn by the operators at the abdominal and thyroid levels. The mean fluoroscopy times were similar between the control group, 1.86 (± 1.27) minutes and the protected group, 2.47 (± 1.90) minutes. The number of recorded cine angiographic runs was also the same at 10.36 (± 2.86) and 10.29 (± 2.35), respectively. The mean waist exposures utilizing the radiation protection method were reduced by 54%, p < .007 and the mean thyroid exposure were reduced by 8%, p = non significant. Conclusions: Th

The study was undertaken to see if the prevalence of AAAs was higher in male and female subjects who had undergone coronary artery bypass grafting (CABG) than the 4% prevalence in men and the 1% prevalence in women reported in many large population based studies. Five-hundred seventeen (517) men and 235 females, 60 years of age and older who had undergone CABG, underwent screening of their abdominal aorta. Forty-seven (47) AAAs were found in men for a prevalence of 9.0% and 12 AAAs were found in women for a prevalence of 5.1%. Of the 47 AAAs found in men, two-thirds for 31 were discovered by the screening process and one-third (16) were known to the subjects. In women, 6 of the 12 AAAs were discovered by the screening process. Smoking, male gender and age were the most significant risk factors.
We conclude that males and females who have undergone CABG have a higher prevalence of AAAs than the population at large. Furthermore, routine screening of the abdominal aorta should be perf

A Single Center Clinical Evaluation of Carotid Stenting for the Treatment of Obstructive Carotid Artery Disease: Experience in a Community Hospital |
| Michael B. DeYoung, DO, Timothy Logan, DO, Julie Burnham, DO, Samer Kazziha, MD |
Objectives. Carotid angioplasty and stenting (CAS) is a less invasive alternative to conventional carotid endarterectomy (CEA). We sought to demonstrate that carotid angioplasty and stenting can be accomplished safely and successfully in a community hospital with results comparable to those attained in clinical trials at academic centers. Background. Trials performed in academic centers have concluded that CAS with an embolic protection device is not inferior to carotid endarterectomy in high-risk patients and has been shown to have fewer complications in the short term. Methods. We report prospective data on fifty consecutive cases utilizing a standardized carotid protocol at our institution performed by a single operator. CAS was completed in 48 high-risk patients. The majority (96%) of procedures included embolic protection devices. Neurological examination and duplex scans were performed at baseline and in follow-up (1 month, 6 months, and 1 year). Long-term re
