Opis:: Objectives The study aim was to analyse the influence of the lead free cap on doses received by interventional cardiologists. The impact of lead free cap on doses to the head were evaluated in number of studies. As different methods used to assess the attenuation properties of protective cap can lead to ambiguous results, a detailed study was performed. Material and Methods The effectiveness of a lead free cap in reducing the doses to the skin was assessed in clinic by performing measurements with thermoluminescent dosimeters attached inside and outside the cap first during individual coronary angiography (CA) or CA/percutaneous transluminal coronary angioplasty (CA/PTCA) procedures and then cumulated during few procedures of the same type. In order to investigate the effect of the cap on reducing the doses to the brain additional measurements were performed with a male Alderson Rando and polymethyl methacrylate (PMMA) phantoms representing the physician and the patient, respectively for different projections. The brain dose per procedure, annual and cumulated during entire working practice were estimated for both cases working with and without the cap. Results The dose reduction factor (RF) for the skin (the quotient of doses outside and inside the cap) vary from 1.1 up to 4.0 in clinical conditions; on average 2.3-fold reduction is observed in the most exposed left temple. The RFs determined for the part of the head covered by the cap range from 1.4 to 1.8 while for the brain from 1.0 to 1.1 depending on the projection. The estimated annual brain dose for interventional cardiologist performing yearly 550 CA/PTCA procedures without any protective shields is 7.2 mGy and it is reduced with the lead free cap by an average factor of 1.1. Conclusions The study results proved the considerable effectiveness of lead free cap to protect the skin but very limited to protect the brain.

Opis:: Iatrogenic embolisation of the right ventricle of the heart by a fragment of one of the most basic ICU devices, which has fractured and detached the central vein catheter, is rarely described in subject literature. Removing such an element from the heart is highly risky and requires the use of very modern techniques and equipment. The Atrieve Vascular Snare™ was employed in the described patient. Therefore, it is necessary to present this process and its effectiveness through an evaluation of the health related quality of life (HRQoL) associated with the perception of health status by those patients. This is a requirement in modern medicine. The main aim of this paper was to evaluate the HRQoL after this embolisation. A 67-year-old patient was referred to the Vascular Surgery Department with Endovascular Interventions Ward, John Paul II Hospital in Kraków, after the defragmenting of the central vein catheter and replacement to the right ventricle of the heart. An endovascular approach through the right common femoral vein (RCFV) under local anesthesia of the groin was chosen as the preferred method for removing the broken catheter fragment. The right ventricle of the heart was reached using a 18-30mm Atrieve Vascular Snare™. A structure consisting of three loops facilitated the quick grasp and removal of the catheter fragment at the first attempt through the RCFV. Despite the short time needed for the procedure, the patient experienced periprocedural ventricular fibrillation (VF) with the necessity of defibrillation. After one successful defibrillation attempt, sinus rhythm was restored. The post-operative course showed no complications whatsoever, and the patient was sent to the General Surgery Ward in order for a new Hickman catheter to be implemented and further parenteral nutrition treatment to be carried out. The endovascular technique with the use of Atrieve Vascular Snare™ is an effective method which was used in the case of our patient under local anesthesia. It provides for the fast, safe and convenient removal of a disrupted and dislocated catheter fragment. It allows one to improve the patient’s HRQoL not only in the short term, but also in the longitudinal (6 months after surgery) follow up.

Opis:: Odkrycie promieniowania jonizującego przyniosło wiele korzyści również w medycynie. Związane z nim ryzyko wywoływania chorób, takich jak nowotwory popromienne czy zaćma, skutkuje koniecznością monitorowania narażenia osób pracujących w ekspozycji na promieniowanie jonizujące za pomocą dozymetrii indywidualnej lub optymalizacji procedur medycznych. Istnieją 3 główne sposoby optymalizacji procedur medycznych – redukcja czasu, zwiększenie odległości oraz stosowanie osłon osobistych i stałych. Wraz z rozwojem nauki i techniki ewoluują sposoby zmniejszania dawki. Poza lepszą osłonnością wzrasta także ergonomia, jak w przypadku osłony Zero-Gravity i lekkich fartuchów bezołowiowych. Rośnie także świadomość konieczności stosowania osłon i prowadzenia zabiegu tak, aby zmniejszyć narażenie zarówno personelu, jak i pacjenta. Celem artykułu jest przedstawienie nowych metod ochrony przed promieniowaniem jonizującym w kontekście powyższych 3 pryncypiów ochrony radiologicznej.
Ionizing radiation as a scientific achievement provides a variety of advantages, e.g., in the medical field. However, it also causes a risk of some illnesses, e.g., cataract or cancer. This results in the need to measure radiation doses and to reduce the unnecessary risk. There are 3 main methods of dose reduction, i.e., shortening the time of exposure, working as far as possible from the X-ray source, and using radioprotective shields. Together with the development of science and technology, dose reduction methods and radioprotection methods have also evolved. Besides improved shielding, the ergonomics is also more advanced, e.g., the zero-gravity shielding or light, and non-lead aprons. What is more, the awareness of using radiological protection and conducting the surgery in the safest way for both the staff and the patient is growing up. The goal of this article is to discuss the newest methods of radiation protection against the background of 3 main protection principles.
