Anthropometric parameters and radiation doses during percutaneous coronary procedures. Phys Med 2022; 100:164-175. [PMID: 35901630 DOI: 10.1016/j.ejmp.2022.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 05/24/2022] [Accepted: 06/27/2022] [Indexed: 11/28/2022] Open
Abstract
PURPOSE Body size is a major determinant of patient's dose during percutaneous coronary interventions (PCI). Body mass index, body surface area (BSA), lean body mass and weight are commonly used estimates for body size. We aim to identify which of these measures and which procedural/clinical characteristics can better predict received dose. METHODS Dose area product (DAP, Gycm2), fluoroscopy DAP rate (Gycm2/min), fluoroscopy DAP (Gycm2), cine-angiography DAP (Gycm2), Air Kerma (mGy) were selected as indices of patient radiation dose. Different clinical/procedural variables were analysed in multiple linear regression models with previously mentioned patient radiation dose parameters as end points. The best model for each of them was identified. RESULTS Overall 6623 PCI were analysed, median fluoroscopy DAP rate was 35 [IQR 2.7,4.4] Gycm2, median total DAP was 62.7 [IQR 38.1,107] Gycm2. Among all anthropometric variables, BSA showed the best correlation with all radiation dose parameters considered. Every 1 m2 increment in BSA added 4.861 Gycm2/min (95% CI [4.656, 5.067]) to fluoroscopy DAP rate and 164 Gycm2 (95% CI [145.3, 182.8]) to total DAP. Height and female sex were significantly associated to a reduction in fluoroscopy DAP rate and total DAP. Coronary angioplasty, diabetes, basal creatinine and the number of treated vessels were associated to higher values. CONCLUSIONS Main determinants of patient radiation dose are: BSA, female sex, height and number of treated vessels. In an era of increasing PCI complexity and obesity prevalence, these results can help clinicians tailoring X-ray administration to patient's size.

Abstract
BACKGROUND Patients can be exposed to high skin doses during complex interventional cardiology (IC) procedures. PURPOSE To identify which clinical and technical parameters affect patient exposure and peak skin dose (PSD) and to establish dose reference levels (DRL) per clinical complexity level in IC procedures. MATERIAL AND METHODS Validation and Estimation of Radiation skin Dose in Interventional Cardiology (VERIDIC) project analyzed prospectively collected patient data from eight European countries and 12 hospitals where percutaneous coronary intervention (PCI), chronic total occlusion PCI (CTO), and transcatheter aortic valve implantation (TAVI) procedures were performed. A total of 62 clinical complexity parameters and 31 technical parameters were collected, univariate regressions were performed to identify those parameters affecting patient exposure and define DRL accordingly. RESULTS Patient exposure as well as clinical and technical parameters were collected for a total of 534 PCI, 219 CTO, and 209 TAVI. For PCI procedures, body mass index (BMI), number of stents ≥2, and total stent length >28 mm were the most prominent clinical parameters, which increased the PSD value. For CTO, these were total stent length >57 mm, BMI, and previous anterograde or retrograde technique that failed in the same session. For TAVI, these were male sex, BMI, and number of diseased vessels. DRL values for Kerma-area product (PKA), air kerma at patient entrance reference point (Ka,r), fluoroscopy time (FT), and PSD were stratified, respectively, for 14 clinical parameters in PCI, 10 in CTO, and four in TAVI. CONCLUSION Prior knowledge of the key factors influencing the PSD will help optimize patient radiation protection in IC.

Abstract
BACKGROUND Optimizing patient exposure in interventional cardiology is key to avoid skin injuries. PURPOSE To establish predictive models of peak skin dose (PSD) during percutaneous coronary intervention (PCI), chronic total occlusion percutaneous coronary intervention (CTO), and transcatheter aortic valve implantation (TAVI) procedures. MATERIAL AND METHODS A total of 534 PCI, 219 CTO, and 209 TAVI were collected from 12 hospitals in eight European countries. Independent associations between PSD and clinical and technical dose determinants were examined for those procedures using multivariate statistical analysis. A priori and a posteriori predictive models were built using stepwise multiple linear regressions. A fourfold cross-validation was performed, and models' performance was evaluated using the root mean square error (RMSE), mean absolute percentage error (MAPE), coefficient of determination (R²), and linear correlation coefficient (r). RESULTS Multivariate analysis proved technical parameters to overweight clinical complexity indices with PSD mainly affected by fluoroscopy time, tube voltage, tube current, distance to detector, and tube angulation for PCI. For CTO, these were body mass index, tube voltage, and fluoroscopy contribution. For TAVI, these parameters were sex, fluoroscopy time, tube voltage, and cine acquisitions. When benchmarking the predictive models, the correlation coefficients were r = 0.45 for the a priori model and r = 0.89 for the a posteriori model for PCI. These were 0.44 and 0.67, respectively, for the CTO a priori and a posteriori models, and 0.58 and 0.74, respectively, for the TAVI a priori and a posteriori models. CONCLUSION A priori predictive models can help operators estimate the PSD before performing the intervention while a posteriori models are more accurate estimates and can be useful in the absence of skin dose mapping solutions.

Abstract
Objective To analyze the radiation dose received by patients during hepatic artery infusion chemotherapy (HAIC) and transarterial chemoembolization (TACE) procedures and the related influencing factors. Methods Data of 162 cases in the HAIC group and 230 cases in the TACE group were collected. The included covariates were Age (<45/45–59/≥60 years), BMI levels (underweight/normal weight/obesity), focus Dye of tumor (present/absent), lesion size (<5cm/≥5cm), superselection (present/absent), hepatic vascular variation (present/absent). The endpoints were postoperative dose-area product (DAP), exposure time and Air kerma (AK). Results Of all included patients, the HAIC group patients were younger than those in the TACE group (P = 0.028). The proportion of patients with large lesions in the HAIC group was higher than the TACE group (45.7% vs. 33.9%, P = 0.019). The proportion of patients who had superselection was lower in the HAIC group as compared to the TACE group (61.7% vs. 82.2%, P < 0.001). Generally, the HAIC group has lower DAP, exposure time and AK by 36.3% (P < 0.001), 38.2% (P < 0.001), and 41.3% (P < 0.001) than the TACE group, respectively. Linear regression analysis showed the procedure method (HAIC/TACE, P < 0.001), type of DSA machine (Pheno/FD20, P < 0.001), BMI levels (P < 0.001), age (P = 0.021), lesion size (<5cm/≥5 cm, P = 0.031) significantly correlated with low DAP. In the HAIC group, the type of DSA machine and BMI correlated with the radiation dose, while in the TACE group, the type of DSA machine, BMI, and lesion size correlated with the radiation dose. Conclusion Compared with TACE, HAIC enables doctors and patients to receive lower radiation doses. Obese patients in both HAIC and TACE groups increase the radiation exposure in interventional doctors and patients, but large lesions only affect the radiation dose in the TACE procedure.

Abstract
The use of fluoroscopy is widespread within different medical specialties. Improper protection may cause significant radiation hazard to medical personnel. To evaluate the concepts on radiation safety and fluoroscopy use among orthopaedic surgeons and to reflect our current training on this issue, a survey was distributed to perform an audit in our department, an academic unit. Twenty-eight orthopaedic surgeons replied. Amongst our participants, 96.4% used a lead apron at all times. Only 33% used a thyroid shield, 67% never used radiation goggles and 96% never used radiation protection gloves. 53.6% and 46.4% of participants position the fluoroscopy incorrectly in the anteroposterior and lateral positions, respectively, during use. There is clearly a need for improved safety amongst orthopaedic surgeons. A literature review was further performed, showing the hazards of fluoroscopy for doctors, including the risk of cataracts, radiation dermatitis, skin cancer and thyroid cancer. Hazards specific to females, including breast cancer risk, and in-utero irradiation of foetus were also thoroughly discussed. Recommendations towards radiation safety and practical measures to reduce fluoroscopy radiation hazard during procedure were made. Education and training to doctors on this invisible hazard is strongly advised.
