Scientific Results

Randomized controlled trials provide the best evidence in clinical trials; however, they do have limitations. In order to evaluate the effectiveness of treatments, population based registries may also yield useful information about the actual practice and they may enable users to carry out a dynamic follow-up. To evaluate the outcome of vascular procedures, the Vascular Registry in Hungary has been established in 2002. This article presents the establishment and functioning of the Vascular Registry and provides information about scientific results obtained during the past years. The Vascular Registry is an internet based database with on-line input. The backup server is provided by the National Institute for Quality and Organizational Development in Healthcare and Medicines. The database collects data in three different fields: interventions for carotid artery, aneurysm (any type) and lower extremity vascular diseases. Twenty five vascular surgical units record interventions in the registry, which corresponds to two thirds of the whole activity. Since joining the Vascunet Group of the European Society for Vascular Surgery, the registry has contributed to several publications based on evaluation of a large common dataset in different fields of vascular surgery. A validation process has been recently performed which confirmed the internal and external validity of the database. The authors conclude that despite unsolved problems related to financing issues, the Vascular Registry has proved to be a useful tool during the past years. In order to take advantage of the registry to its fullest, measures should be taken to achieve a more complete data recording, increase publication activity on the national dataset, improve the flow of information during operation and develop a system of regular feedback.

Abstract: Introduction: Aneurysm of the extracranial carotid artery is a rare condition and there is a diversity in the etiology. The proper treatment could be a real challenge for the surgeons. Aim: Analysis of perioperative and long term results of invasive treatment for carotid artery aneurysm. Method: A retrospective review was conducted of patients who had open or endovascular surgery due to carotid artery aneurysm through the last 13 years at the Department of Vascular Surgery of the Semmelweis University and at the Department of Surgery of the University of Szeged. Medical history, characteristics of the aneurysms, therapy and the follow-up results were reviewed. Results: Over the study period, 25 interventions were performed due to carotid artery aneurysm. There were 10 men and 15 women with a mean age of 57.8 ± 15.15 years. Seventeen patients (68%) were symptomatic. The mean aneurysm diameter was 26.8 ± 11.25 mm. The underlying etiology was atherosclerosis in eleven (44%), prior carotid endarterectomy in four (16%), infection in four (16%) and other cause (connective tissue disease, dissection, trauma) in six (24%) cases. Nineteen patients underwent open surgery, six underwent endovascular treatment. Death within 30 days was documented in one (4%) case. The mean postoperative hospital stay was 4.52 ± 2.38 days. Three (12%) patients required reintervention postoperatively. Peripheral nerve injuries were detected in four (16%) patients, all after open surgery. No stroke was documented within 30 days. The mean follow-up was 41.2 ± 38.54 months. Five (24%) deaths were not related to the carotid artery disease. One patient had stroke, one had transient ischaemic attack (TIA), and in two cases asymptomatic internal carotid artery occlusion was described. Conclusion: Both open surgery and endovascular intervention can be safely applied in the treatment of carotid artery aneurysm. Considering the variable etiology and rarity, we recommend to perform the interventions in vascular surgery centres. Orv Hetil. 2019; 160(21): 815–821.

The Fourier Transform

In the past few years on-line digital television frame store devices coupled to computers have been employed to attempt to measure the microscope parameters of defocus and astigmatism. The ultimate goal of such tasks is to fully adjust the operating parameters of the microscope and obtain an optimum image for viewing in terms of its information content. The initial approach to this problem, for high resolution TEM imaging, was to obtain the power spectrum from the Fourier transform of an image, find the contrast transfer function oscillation maxima, and subsequently correct the image. This technique requires a fast computer, a direct memory access device and even an array processor to accomplish these tasks on limited size arrays in a few seconds per image. It is not clear that the power spectrum could be used for more than defocus correction since the correction of astigmatism is a formidable problem of pattern recognition.

Peripheral Aneurysms

Carotid artery aneurysms account for 4% of peripheral aneurysms and may present as a neck mass, with hemispheric ischaemic symptoms, or with symptoms secondary to local compression. This case explores the presentation, investigations and management of a presumed mycotic common carotid artery aneurysm in a 77-year-old male, which was repaired using end-to-end interposition vein graft using long saphenous vein. This report discusses the aetiology, presentation and surgical management for carotid artery aneurysms, as well as focusing on that of the rare mycotic carotid artery aneurysm.

ObjectivesData on the problem of physical activity-related injury (PARI) in university students and the risk factors for PARI among different genders are rare. We conducted a multicentre population-based study to investigate the occurrence of PARI and to explore the gender-specific risk factors for PARI among Chinese university students.DesignCross-sectional study.ParticipantsA total of 5341 students in grades 1–3 at eight universities in four Chinese cities were selected to complete the online questionnaires during March and April 2017. The questionnaires assessed sociodemographic characteristics, physical activity PA) involvement, sleep duration, sedentary behaviour and PARI experiences in the past 12 months.Main outcome measuresPARI during the past 12 months.ResultsAmong the 5341 participants, 1293 suffered from at least one PARI in the past 12 months, with an overall incidence rate of 24.2% (males: 26.2%, females: 23.2%) and an injury risk of 0.38 injuries/student/year (males: 0.48, females: 0.32). Over half of the injured (57.3%) experienced a withdrawal time of PA and nearly two-fifths (39.6%) required medical attention. Irrespective of gender, Shantou and Xi’an students, sports team members and those who engaged in sports and leisure-time vigorous-intensity PA (VPA) at a higher frequency were more likely to suffer from PARI. Male students who participated in sports and leisure-time VPA for long durations had a greater likelihood of sustaining PARI, while having a chronic condition and being involved in sports and leisure-time moderate-intensity PA at a higher frequency and longer duration were potential contributors to PARI among females.ConclusionsThe occurrence of PARI and its risk factors differed by gender, which provides a direction towards developing targeted and effective gender-specific preventative programmes to protect Chinese university students from PARI.
