Currently, due to the progressive development of diagnostic technologies, the detection of arteriovenous malformations (AVM) of different anatomical locations is increasing. In this case, intraorgan AVMs are often an accidental find. The article presents the studies of domestic and foreign authors of various types of vascular anomalies, collected information about the arteriovenous malformations occurring in different organs according to the literature. The article presents our own observations of AVMs of the lungs and spleen, obtained using CT angiography.Despite the very rare occurrence of intraorgan AVMs, physicians should be aware of the possibility of such vascular pathology. It is necessary to assign additional diagnostic methods to detect AVM, primarily CT angiography.

Objective. Arteriovenous malformations (AVMs) are an uncommon vascular pathology that remains challenging to accurately diagnose and successfully treat. This study introduces a novel way to evaluate AVM treatment outcomes using transarterial lung perfusion scintigraphy (TLPS) and reports our treatment results. Material and Methods. The patients treated for extracranial AVMs were studied retrospectively. Diagnosis and outcomes were based on clinical data, ultrasonography, magnetic resonance imaging, computed tomography, angiography, and TLPS studies. The influence of gender; location, form, and stage of AVMs; first attempt at treatment; and treatment modalities was analyzed. Outcomes were defined as positive (cure, improvement, and remission) or negative (no remission and aggravation). Results. Of the 324 patients with congenital vascular malformations, 129 (39.8%) presented with AVMs, and the data of 56 treated patients with AVMs were analyzed. Of the 29 patients in the endovascularly treated group, 15 in the surgically treated group, and 12 in the combined treatment group, 24 (82.8%), 14 (93.3%), and 10 patients (83.3%), respectively, had positive outcomes (P>0.05). All outcomes were positive in surgically treated patients with extratruncular limited AVMs, and these patients were more likely to be cured as compared with those who had other forms of AVMs (OR, 5.8; 95% CI, 1.1–29; P=0.02). The patients with more advanced AVMs (stages III and IV) and with AVMs in the gluteal and pelvic region were more likely to have the worst outcomes than those with stage II AVMs (OR, 8.2; 95% CI, 1–72; P=0.03) and with AVMS in other locations (OR, 5.8; 95% CI, 1.1–29; P=0.02), respectively. Gender and age did not significantly influence treatment results (P>0.05). The TLPS data of 17 patients showed AV shunting ranging from 0% to 92%, which combined with other results helped identify 9 patients who needed further interventions, 6 who were treated successfully, and 2 who had insignificant shunting. Conclusions. The best outcomes were achieved in surgically treated patients with localized lesions and less advanced AVMs. For the first time in Lithuania, a modified TLPS method has been introduced that enhances a hemodynamic assessment of AV shunting and provides with a more accurate evaluation of AVMs to better serve in planning future treatments.

Introduction. A variety of concepts and approaches to the analysis of the etiology and pathogenesis of temporomandibular joint dysfunctions, results in increased interest in the search for highly informative diagnostic methods, especially at the stage of pre-clinical manifestations. Objectives. The aim of the study was to analyze the possibilities of modern technologies in diagnostics of temporomandibular joint dysfunctions. Materials and methods. We studied original papers on the diagnostics of temporomandibular joint dysfunctions from several databases: Russian State Library, eLibrary, PubMed, The Cochrane Library, Google Scholar. Results. The review presents both generally accepted and alternative approaches to the diagnostics of different clinical manifestations in temporomandibular joint dysfunctions. We described the diagnostic value of occlusal disorders analysis in universal articulators, virtual articulators, T-scan system. Capabilities of teleroentgenography, axiography, electromyography, computed and magnetic resonance imaging were estimated as well. Conclusions. The literature review on the problem of diagnosing the temporomandibular joint dysfunctions showed a scientifically based spectrum of diagnostic capabilities of modern dentistry, a trend in the development of highly informative digital diagnostic technologies. Due to the diversity of the etiology and pathogenesis of the temporomandibular joint dysfunctions further in-depth studies of this issue are required.

A case with ophthalmological manifestations of two genetically determined diseases in one patient with a progressive decrease in visual functions is considered. The clinical picture and modern diagnostic methods necessary for the clinical diagnosis are reflected. The rare occurrence of combinations of congenital diseases of the cornea and optic nerve disc requires special attention during ophthalmological examination. Key words: corneal dystrophy, comorbidity, inherited diseases, optic nerve atrophy, optic disc drusen.

Ocular tuberculosis is a serious disease with a long recurrent course, often leading to a significant decrease in the visual functions and quality of life of patients as well as disability. In recent years, the incidence rate of the ocular tuberculosis in the Russian Federation has been declining: in 2016, according to a number of authors, its incidence amounted to 5.2%.Purpose. To systematize literature data on the topic of ocular tuberculosis.Materials and methods. We reviewed literature available on elibrary.ru, cyberleninka.ru websites and in “Clinical Ophthalmology” journal. Results. We suggested classification of the ocular tuberculosis lesions, analyzed modern diagnostic methods and treatment regimens and evaluated their effectiveness.Conclusions. Literature review revealed that in order to improve the quality of detection, diagnosis and treatment of ocular tuberculosis, joint efforts of ophthalmologists and phthisiologists as well as use of modern methods of tuberculinodiagnosis are essential.

Intracranial Dural Arteriovenous Fistulae

Abstract BACKGROUND: Indocyanine green videoangiography (IGV) raises important limitations when we use it in vascular pathology, especially in cases with arterialization of the venous system such as arteriovenous malformations and fistulae. OBJECTIVE: Our objective was to provide a simple procedure that overcomes the limitations of conventional IGV. We define IGV in negative (IGV-IN), so-called because, in its first phase, the vessel to analyze is clipped, and we report 3 cases of intracranial dural arteriovenous fistulae treated with this procedure. METHODS: In 2011, we applied IGV-IN to 3 patients at our center with Borden type III intracranial arteriovenous fistulae. RESULTS: In all 3 cases, IGV-IN enabled both diagnosis and post-dural arteriovenous fistula exclusion control in 1 integrated procedure no longer than 1 minute, requiring only 1 visualization. CONCLUSION: IGV-IN is an improvement over the conventional IGV method and is able to provide more information in a shorter period of time. It is an intuitive and highly visual procedure, and, more importantly, it is reversible. Studies with larger samples are necessary to determine whether IGV-IN can further reduce the need for postoperative digital subtraction angiography.
