BACKGROUND: Percutaneous rhizotomy of the Gasserian ganglion is a well-established intervention for patients suffering from refractory trigeminal pain, not amenable to pharmacological management or microvascular decompression. Traditionally conducted under fluoroscopic guidance using Hartel's technique, this study investigates a modified approach employing low-dose CT guidance to achieve maximal procedural precision and safety with the emphasis on minimizing radiation exposure. METHODS: A retrospective analysis of patients undergoing percutaneous rhizotomy of the Gasserian ganglion at our institution was undertaken. Procedures were divided into fluoroscopy and CT-guided foramen ovale (FO) cannulation cohorts. Radiation doses were assessed, excluding cases with incomplete data. The study included 32 procedures in the fluoroscopy group and 30 in the CT group. RESULTS: In the CT-guided group, the median effective dose was 0.21 mSv. The median number of CT scans per procedure was 4.5, and the median procedure time was 15 min. Successful FO cannulation was achieved in all 30 procedures (100%). In the fluoroscopy group, the median effective dose was 0.022 mSv, and the median procedure time was 15 min. Cannulation of FO was successful in 31 of 32 procedures (96.9%). The only complications in the CT-guided group were three minor cheek hematomas. Immediate pain relief in the CT-guided group was reported in 25 of 30 procedures (83.3%), 22 of 30 (73.3%) provided relief at one month, and 10 of 18 (55.6%) procedures resulting in pain relief at one month continued to provide relief after two years. CONCLUSION: Low-dose CT-guided percutaneous rhizotomy conducted in the radiology suite carries negligible radiation exposure for patients and eliminates it for personnel. This method is fast, simple, precise, and carries a very low risk of complications.

Dysfagie neboli porucha polykání je častým problémem u stárnoucí populace, přičemž její výskyt narůstá s věkem. Fyziologická ztráta motorických a senzitivních funkcí vede k presbyfagii, což je nepravá dysfagie u zdravých jedinců. Skutečná dysfagie vzniká při komplikacích způsobených akutním onemocněním. Incidence dysfagie je vysoká, v USA se udává, že 6–7 % osob trpí touto poruchou. U seniorů nad 65 let je aspirační bronchopneumonie, často způsobená dysfagií, čtvrtou nejčastější příčinou úmrtí. Po cévní mozkové příhodě (CMP) se dysfagie vyskytuje u 37–38 % pacientů a u neurodegenerativních onemocnění, jako je demence, až u 93 % pacientů. Dysfagie ve stáří ovlivňuje všechny fáze polykání: orální přípravnou, orální transportní, faryngeální a ezofageální. Diagnostika vyžaduje spolupráci specialistů a zahrnuje metody jako FEES a VFSS. Terapie se zaměřuje na udržení bezpečného příjmu potravy a zahrnuje logopedickou intervenci, cvičení a manévry na zlepšení svalové síly a koordinace. Kompenzační techniky a rehabilitační postupy jsou klíčové pro prevenci komplikací. Presbyfagie je často opomíjená, a proto je důležitá mezioborová spolupráce a edukace rodinných příslušníků pro zajištění adekvátní péče.

Dysphagia, or swallowing disorder, is a common problem in the aging population, with its incidence increasing with age. The physiological loss of motor and sensory functions leads to presbyphagia, which is a false dysphagia in healthy individuals. True dysphagia occurs with complications caused by acute illness. The incidence of dysphagia is high, with 6-7% of people in the USA reported to suffer from this disorder. In the elderly over 65, aspiration bronchopneumonia, often caused by dysphagia, is the fourth most common cause of death. After a stroke, dysphagia occurs in 37-38% of patients and in neurodegenerative diseases such as dementia in up to 93% of patients. Dysphagia in old age affects all phases of swallowing: oral preparatory, oral transport, pharyngeal and oesophageal. Diagnosis requires the collaboration of specialists and includes methods such as FEES and VFSS. Therapy focuses on maintaining safe eating and includes speech therapy intervention, exercises and manoeuvres to improve muscle strength and coordination. Compensatory techniques and rehabilitation procedures are key to preventing complications. Presbyphagia is often neglected, so interdisciplinary collaboration and education of family members is important to ensure adequate care.

INTRODUCTION: The reduction of fluoroscopic exposure during catheter ablation of supraventricular arrhythmias is widely adopted by experienced electrophysiology physicians with a relatively short learning curve and is becoming the standard of care in many parts of the world. While observational studies in the United States and some parts of Western Europe have evaluated the minimal fluoroscopic approach, there are scarce real-world data for this technique and the generalizability of outcomes in other economic regions. METHOD: The AALARA study is a prospective, observational, multicenter, and multinational open-label study. Patients were recruited from 13 countries across Central Eastern Europe, North and South Africa, the Middle East, and the CIS (Commonwealth of Independent States), with different levels of operator expertise using minimal fluoroscopic exposure techniques. Data on radiation exposure, procedural success, complications, recurrence, and quality of life changes were collected and analyzed. RESULT: A total of 680 patients were enrolled and followed for 6 months. The majority were ablation naïve with the commonest arrhythmia ablated being typical AVNRT (58%) followed by Atrial Flutter (23%). Zero fluoroscopy exposure was observed in almost 90% of the cases. Fluoroscopy was most commonly used during the ablation phase of the procedure. We observed a high acute success rate (99%), a low complication rate (0.4%), and a 6-month recurrence rate of 3.8%. There was a significant improvement in the patient's symptoms and quality of life as measured by patient global assessment. CONCLUSION: The routine use of a 3D mapping system during right-sided ablation was associated with low radiation exposure and associated with high acute success rate, low complications, and recurrence rate along with significant improvement in quality of life. The data confirm the reproducibility of this approach in real-world settings across different healthcare systems, and operator experience supporting this approach to minimize radiation exposure without compromising efficacy and safety. TRIAL REGISTRATION: NCT04716270.

PURPOSE OF THE STUDY: Open (incisional) biopsies have long been accepted as the gold standard in diagnosing bone and soft tissue tumors. However, the main disadvantage of this method is that it can lead to increased contamination, hematoma, infection, and pathological fracture. Compared to open biopsies, percutaneous core needle biopsies are less invasive, do not require hospitalization, have low costs and low complication rates, and there is no need for wound healing in cases that require radiotherapy. This study evaluated the diagnostic accuracy and reliability of percutaneous core needle biopsy. MATERIAL AND METHODS: The study included the results of 250 percutaneous core needle biopsies of 244 patients who presented at the tertiary university hospital between September 2012 - September 2022 and were diagnosed with a bone or soft tissue tumor using the percutaneous core needle biopsy method and then underwent surgical excision in the Orthopaedics and Traumatology Clinic. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy rates were calculated for the percutaneous core needle biopsy method according to the compatibility of the results. RESULTS: A fluoroscopy-guided percutaneous Jamshidi needle biopsy performed by an orthopedist for lesions originating from the bone has a diagnostic accuracy of 96%. CT-guided percutaneous Jamshidi needle biopsy performed by a radiologist for lesions originating from the bone has a diagnostic accuracy of 88.9%. Percutaneous Tru-cut needle biopsy performed by an orthopedist without imaging guidance for lesions originating from soft tissue has a diagnostic accuracy of 92%. USGguided percutaneous Tru-cut needle biopsy performed by a radiologist for lesions originating from soft tissue has a diagnostic accuracy of 96,7% (p<0.001). DISCUSSION: The diagnostic accuracy of open biopsies ranges from 91% to 99% in the literature. Additionally, the diagnostic accuracy of core needle biopsies in recent studies ranges from 76% to 99%. Compared to the literature, our study has shown that biopsies performed by orthopedic specialists have a high diagnostic power (96% for bone-derived lesions; 92% for soft tissue-derived lesions). CONCLUSIONS: Percutaneous core needle biopsy is highly effective and reliable in diagnosing bone and soft tissue tumors. Managing patients by a team using a multidisciplinary approach will increase diagnostic success. KEY WORDS: core needle biopsy, percutaneous, diagnostic accuracy, radiology guided biopsy, bone and soft tissue tumors.

Interventional electrophysiology offers a great variety of treatment options to patients suffering from symptomatic cardiac arrhythmia. Catheter ablation of supraventricular and ventricular tachycardia has globally evolved a cornerstone in modern arrhythmia management. Complex interventional electrophysiological procedures engaging multiple ablation tools have been developed over the past decades. Fluoroscopy enabled interventional electrophysiologist throughout the years to gain profound knowledge on intracardiac anatomy and catheter movement inside the cardiac cavities and hence develop specific ablation approaches. However, the application of X-ray technologies imposes serious health risks to patients and operators. To reduce the use of fluoroscopy during interventional electrophysiological procedures to the possibly lowest degree and to establish an optimal protection of patients and operators in cases of fluoroscopy is the main goal of modern radiation management. The present manuscript gives an overview of possible strategies of fluoroscopy reduction and specific radiation protection strategies.

CONTEXT: Endourological procedures frequently require fluoroscopic guidance, which results in harmful radiation exposure to patients and staff. One clinician-controlled method for decreasing exposure to ionising radiation in patients with urolithiasis is to avoid the use of intraoperative fluoroscopy during stone intervention procedures. OBJECTIVE: To comparatively assess the benefits and risks of "fluoroscopy-free" and fluoroscopic endourological interventions in patients with urolithiasis. EVIDENCE ACQUISITION: A systematic review of the literature from 1970 to 2022 was performed using the MEDLINE/PubMed, Embase, and Cochrane controlled trials databases and ClinicalTrials.gov. Primary outcomes assessed were complications and the stone-free rate (SFR). Studies reporting data on ureteroscopy and percutaneous nephrolithotomy (PCNL) were eligible for inclusion. Secondary outcomes were operative duration, hospital length of stay, conversion from a fluoroscopy-free to a fluoroscopic procedure, and requirement for an auxiliary procedure to achieve stone clearance. EVIDENCE SYNTHESIS: In total, 24 studies (12 randomised and 12 observational) out of 834 abstracts screened were eligible for analysis. There were 4564 patients with urolithiasis in total, of whom 2309 underwent a fluoroscopy-free procedure and 2255 underwent a comparative fluoroscopic procedure for treatment of urolithiasis. Pooled analysis of all procedures revealed no significant difference between the groups in SFR (p = 0.84), operative duration (p = 0.11), or length of stay (p = 0.13). Complication rates were significantly higher in the fluoroscopy group (p = 0.009). The incidence of conversion from a fluoroscopy-free to a fluoroscopic procedure was 2.84%. Similar results were noted in subanalyses for ureteroscopy (n = 2647) and PCNL (n = 1917). When only randomised studies were analysed (n = 12), the overall complication rate was significantly in the fluoroscopy group (p < 0.001). CONCLUSIONS: For carefully selected patients with urolithiasis, fluoroscopy-free and fluoroscopic endourological procedures have comparable stone-free and complication rates when performed by experienced urologists. In addition, the conversion rate from a fluoroscopy-free to a fluoroscopic endourological procedure is low at 2.84%. These findings are important for clinicians and patients, as the detrimental health effects of ionising radiation are negated with fluoroscopy-free procedures. PATIENT SUMMARY: We compared treatments for kidney stones with and without the use of radiation. We found that kidney stone procedures without the use of radiation can be safely performed by experienced urologists in patients with normal kidney anatomy. These findings are important, as they indicate that the harmful effects of radiation can be avoided during kidney stone surgery.

PURPOSE: Treatment of pelvic fractures is often complicated. Here, we intended to evaluate the intraoperative benefits of using 2D computer navigation when compared with traditional fluoroscopy on X-ray burden, surgical time and screw placement accuracy. METHODS: In this study, we retrospectively evaluated the records of 25 patients who underwent osteosynthesis of a posterior pelvic fracture using fluoroscopy at the University Hospital Ostrava, Czech Republic between 2011 and 2019, and 32 patients from the same department and period in whom 2D computer navigation was used. RESULTS: Intraoperative X-ray burden was significantly lower in the group with 2D computer navigation (median 650 vs 1024 cGy/cm2), as was the duration of the surgery (41 vs 45 min). This was most obvious where two screws were inserted (X-ray dose of 994 vs 1847 cGy/cm2 and 48 vs 70 min, respectively). Correction of the path for wire placement after the original drilling was necessary in 2 patients (6%) from the 2D computer navigation group and 15 patients from the fluoroscopy group (60%). Still, no malposition of the screws nor dislocation of the posterior pelvic segment after 12 months was observed in any patient of either group; of complications, only three superficial infections in the 2D navigation group and 2 in the fluoroscopy group were observed. CONCLUSION: 2D computer navigation is a safe and accurate method for placement of screws during posterior pelvic fracture osteosynthesis, associated with lower intraoperative radiation burden and shorter surgical times compared to standard fluoroscopy, especially if two screws are inserted.

The aim of this systematic review is to undertake a critical appraisal of the evidence in the published literature concerning the conversion factors between kerma-area product (PKA) and effective/organ dose (DCED_PKA, DCHT_PKA) for cardiac interventional fluoroscopy procedures performed in adults and paediatric patients and to propose reference conversion factors to help standardize dose calculations. A search strategy utilizing MeSH headings in three databases identified 59 (adult) and 37 (paediatric) papers deemed eligible for the review. Exclusion criteria were adopted to select data only from publications which established DCED_PKAin patients using the ICRP 103 tissue weighting factors. A time restriction from January 2007 was introduced in the search to capture the evolving trends of utilization of fluoroscopy-guided intervention technologies only in recent years. The suggested DCED_PKAand DCHT_PKAwere synthesized by calculating the weighted averages of the values reported by the authors with weights corresponding to the study sample size. Eighteen studies for both adult (9) and paediatric (9) patients matching the search terms fulfilled the inclusion criteria. The suggested value for DCED_PKAin adult patients amounts to 0.24 mSv Gy-1cm-2. The suggested values for DCHT_PKAranged from a minimum of 0.15 mSv Gy-1cm-2for the female breast to a maximum of 0.97 mSv Gy-1cm-2for the lungs. The suggested values for DCED_PKAin paediatric patients ranged from 3.45 mSv Gy-1cm-2for the new-born to 0.49 mSv Gy-1cm-2in the 15 years age class. The suggested values for DCHT_PKAranged from a minimum of 0.33 mSv Gy-1cm-2for bone marrow in the 15 years age class to a maximum of 11.49 mSv Gy-1cm-2for the heart in the new-born. To conclude, values of DCED_PKA/DCHT_PKAwere provided for calculating effective/organ doses in cardiac interventional procedures. They can be useful for standardizing dose calculations, hence for comparison of the radiation detriment from different imaging procedures and in the framework of epidemiologic studies.
