“…The radiation exposure rate was comparable to that registered for all patients during complex lesion angioplasty used for similar indications. 28,29 This study was limited by its non-randomized nature and lack of a control group. Optimally designed research would include a group of patients with significant disease of the carotid arteries.…”

Objectives Management of patients undergoing coronary artery bypass grafting (CABG) with obstructive disease of the carotid arteries is still a matter of debate. We compared the results of staged carotid artery stenting (CAS) before CABG in patients with carotid lesions. Materials and Method Patients with significant carotid artery disease who were deemed to simultaneously suffer from an obstructive coronary artery disease requiring CABG from 2008 to 2018 were screened and enrolled in this study. We performed a staged CAS in cases with ≥60% stenosis and neurological symptoms or asymptomatic patients with ≥80% carotid artery stenosis. Patients with bilateral carotid lesions received sequential CAS within three weeks. Six weeks after the CAS procedure, all patients underwent CABG. Results A total of 142 patients were included. Eighty-five of these had neurological symptoms, while the remaining 40% were asymptomatic. Thirty-one patients underwent sequential CAS for bilateral lesions. The cerebrovascular event (CVE) following CAS (3 patients) and CABG (3 patients) was 4.2%. There was only a single case of mortality in this cohort. Although it was not statistically significant, CVE after CABG was more frequent in patients with bilateral carotid disease. Conclusions Our results showed that staged CAS could be performed with minimal adverse outcomes in patients suffering from a simultaneous occlusive disease of carotids and coronary arteries before CABG. Bilateral CAS will further decrease cerebrovascular events and could be performed consequently or concomitantly.

“…The amount of scatter radiation (SR) exiting the patient can be quite significant and exposes physicians performing the procedure and staff in the room to substantial radiation (Tarighatnia et al 2018). The cumulative effect of the exposure to scatter radiation are possible increases in the incidence of cancer, cataracts, and vascular disease (Andreassi et al 2016; Roguin et al 2013; Rajaraman et al 2016).…”

Background: Nearly all radiation safety courses teach that scatter radiation around the x-ray table falls with the inverse of the distance from the imaging site. Humans, however, are complex x-ray reflectors and the application of the inverse square law to clinical imaging is only assumed. Methods: We measured scatter radiation at two positions where staff commonly stand around the x-ray table. Using an anthropomorphic human phantom, human and pig cadavers, and a glass sphere, we measured scatter radiation levels in each position, and then 2- and 3-fold the distance from the imaging site. We compared the measured scatter radiation to that predicted by the common inverse square law and a more detailed geometric inverse square law. Results: In all but the glass sphere, scatter radiation was much higher below the table (68–74% of all scatter radiation, depending on model and position) than above the table (26–32% of scatter radiation, p < 0.01). Scatter radiation fell with increasing distance from the table, but above the table both inverse square laws significantly over-estimated the benefit of stepping back (19–93% overestimation by geometric inverse square law at 2-fold distance, 14–46% at 3-fold). In addition, a pelvis in the phantom appeared to cause significant scatter radiation field anomalies at the angiographer position. Conclusion: Stepping back from the table does not reduce scatter radiation levels as much as the inverse square law predicts. The geometric inverse square law best predicts the reduction in scatter radiation below the table, but above the table it too overestimates the benefit of stepping back. The irregularity of the scatter radiation field should be taken into account by scatter radiation shielding systems.
