چکیده

این پژوهش با هدف اندازه‌گیری دز تجمعی پرتو دریافتی پزشک در اندام‌های محیطی (دست‌ها و پاها) حین انجام آنژیوگرافی بیماران مبتلا به آنوریسم مغزی انجام شد. مطالعه به‌صورت میدانی–مقطعی طی بهمن ۱۴۰۳ تا خرداد ۱۴۰۴ در بیمارستان امام حسین (ع) تهران بر روی ۱۵ بیمار متوالی صورت گرفت. برای ثبت دز جذبی از دزیمترهای ترمولومینسانس 200GR- در چهار ناحیه اندام‌های محیطی استفاده و هم‌زمان پارامترهای فنی دستگاه شامل kVp، mAs، DAP و زمان فلوروسکوپی ثبت گردید. نتایج نشان داد بیشترین پرتوگیری مربوط به دست چپ پزشک (میانگینµSv‎ 3/34±5/79؛ حداکثر ‎µSv142) و کمترین میزان مربوط به دست راست (میانگین ‎µSv‎ 8/0±7/18) بود. توزیع دز جذبی از بیشترین به کمترین به‌ترتیب شامل دست چپ، پای چپ، پای راست و دست راست گزارش شد. تحلیل آماری بیانگر همبستگی بسیار قوی و معنادار بین زمان فلوروسکوپی و دز کل ( 001/0p < ، 0/1 r = )و نیز ارتباط مثبت بین شاخص DAP و میزان پرتوگیری بود. پرتوهای یونیزان با وجود نقش حیاتی در تشخیص و درمان، در مواجهه تجمعی شغلی می‌توانند خطرات دیررس مانند سرطان، آب‌مروارید و آسیب‌های ژنتیکی ایجاد کنند. پزشکان آنژیوگرافی به دلیل نزدیکی به میدان تابش در معرض بالاترین خطر هستند. یافته‌ها بر ضرورت رعایت اصل ALARA، استفاده صحیح از تجهیزات حفاظتی، مدیریت زمان تابش، آموزش مستمر و استاندارد سازی پروتکل‌ها برای کاهش مواجهه پرتویی و ارتقای ایمنی شغلی تأکید دارد. محدودیت این مطالعه انجام بر روی یک پزشک و تعداد محدود عمل ها بود و تعمیم نتایج نیازمند بررسی‌های گسترده‌تر است.

چکیده [English]

This study aimed to measure the cumulative radiation dose received by a neurointerventional physician in peripheral organs (hands and feet) during cerebral aneurysm angiography procedures. A field-based cross-sectional study was conducted between February 2025 and June 2025 at Imam Hossein Hospital, Tehran, involving fifteen consecutive patients diagnosed with cerebral aneurysm. Thermoluminescent dosimeters (TLD-200GR) were placed at four peripheral sites to record the absorbed dose, while the technical parameters of the angiography system including kVp, mAs, dose–area product (DAP), and fluoroscopy time were simultaneously documented. The results showed that the left hand received the highest radiation exposure (mean ± SD: 79.5 ± 34.3 µSv; maximum: 142 µSv), while the right hand had the lowest (mean ± SD: 18.7 ± 8.0 µSv). The distribution of absorbed dose from highest to lowest was as follows: left hand, left foot, right foot, and right hand. Statistical analysis revealed a strong and significant correlation between fluoroscopy time and the physician’s total body absorbed dose (r = 1.0; p < 0.001), as well as a positive relationship between DAP and radiation exposure. Although ionizing radiation plays a crucial role in diagnosis and therapy, cumulative occupational exposure may lead to late effects such as cancer, cataracts, and genetic damage. Interventional physicians are among the most at-risk healthcare professionals due to their proximity to the radiation field. The findings emphasize the importance of adhering to the ALARA principle, proper use of protective equipment, optimization of fluoroscopy time, continuous radiation safety training, and protocol standardization to minimize exposure and enhance occupational safety. The study’s main limitation was the single-operator design and limited number of procedures, suggesting the need for further large-scale investigations.
