The development and wide use of instrumental investigational methods, including multispiral computed tomography, computed tomography with angiography, duplex scanning of blood vessels, subtraction angiography, enabled diagnosis of rare diseases, in particular, of the intrahepatic arterioportal fistulae (IAPF). Methods of surgical treatment of this pathology include both open surgery and endovascular treatment with the use of embolizing implants or coils. The article presents a clinical case of diagnosis and endovascular treatment of IAPF in a 33‑year‑old patient, hospitalized in the Center of Interventional Neuroradiology at Feofaniya Clinical Hospital. The choice of the surgical treatment was based on the account of indications and contraindications to the intervention. The endovascular method was used: exclusion of the intrahepatic arterioportal fistulae by means of implantation of micro‑coils Nester 20 мм, MReye 20 mm, Tornado 10–4 mm. Positive dynamics was observed in the long‑term postoperative period (after 3 months), the control was performed based on such criteria as complaints’ absence, normalization of laboratory parameters, positive dynamics of the data of control hepatic angiography. IAPF elimination promoted the reduction of portal hypertension, and improvement of functional liver state. Endovascular method of treatment of patients with arterioportal fistulae is the method of choice at this pathology. The advantages of endovascular method include the minimization of intraoperative and postoperative complications, the shorter postoperative rehabilitation period. In case of the necessity for other method of surgical treatment, one should follow the indications and contraindications to the surgical intervention.

Object The goal of this report was to describe the safety and effectiveness of nucleus ventralis intermedius (VIM) thalamotomy performed with the Leksell Gamma Knife (GK) for the treatment of essential tremor (ET). Methods One hundred seventy-two patients underwent a total of 214 VIM thalamotomy procedures with the Leksell GK between February 1994 and March 2007 for treatment of disabling ET. Eleven patients were lost to follow-up less than 1 year after the procedures, so that in this report the authors describe the results in 161 patients who underwent a total of 203 thalamotomies (119 unilateral and 42 bilateral). Results There were statistically significant decreases (p < 0.0001) in tremor scores for both writing and drawing. The mean postoperative follow-up duration for all patients was 44 ± 33 months. Fifty-four patients have been followed for more than 60 months posttreatment. There were 14 patients who suffered neurological side effects that were temporary (6) or permanent (8), which accounted for 6.9% of the 203 treatments. All complications were related to lesions that grew larger than expected. Conclusions A VIM thalamotomy with the Leksell GK offers a safe and effective alternative for surgical treatment of ET. It is particularly applicable to patients who are not ideal candidates for deep brain stimulation but can be offered to all patients who are considering surgical intervention for ET.

AbstractBoth typical and atypical antipsychotic psychotropics have been reported to cause ischemic priapism presumptively secondary to alpha1-adrenergic blockade. This condition is a urologic emergency for if not evaluated and treated appropriately, long-term sequelae include erectile dysfunction and impotence. This paper addresses the first reported case of priapism requiring surgical intervention presumed to be secondary to ziprasidone. Increased clinician and patient education regarding priapism is required in order to minimize this adverse event and to maximize immediate treatment.

Objective ‒ to determine the features of the functioning of the circulatory system in patients with arteriovenous malformations (AVM) of the brain after endovascular operations with long-term observation.Materials and methods. 479 patients with cerebral AVM were examined and treated, of which 377 (78.7 %) were men and 102 (21.3 %) were women. The average age of patients was (27.5±3.5) years. Patients aged 18‒30 years predominated (75.4 %). A dynamic observation of 347 patients after endovascular treatment after 3, 6, 12 and 24 months and more was carried out. Patients underwent cerebral angiography, computed tomography, magnetic resonance imaging, single-photon emission computed tomography, echocardiography, Doppler cardiography, electrocardiography, duplex scanning of cerebral vessels.Results. The study shows the effect of arteriovenous shunting on cerebral and systemic hemodynamics in general. Switching off AVM from the cerebral blood flow improved cerebral hemodynamics already in the early postoperative period, the changes were more significant after 3‒6 months of observation and in some cases reached values ​​in healthy individuals 2 years after the operation. In 52.8 % of patients with AVM, systemic circulation disorders occurred due to an increase in heart rate, minute and stroke blood volumes, left ventricular ejection fraction with an increase in mechanical load on the heart, which led to changes in systolic contraction and diastolic relaxation of the left ventricle of the heart with the development of heart failure. Switching off the AVM from the cerebral blood flow did not cause significant changes in heart functions in the early postoperative period; positive changes occurred over a long period. Dynamic observation showed a positive restructuring of the functioning of the circulatory system in patients after endovascular exclusion of the malformation.Conclusions. Arteriovenous malformations are hemodynamically active systems that lead to hemodynamic-perfusion changes, both at the local and at the general hemodynamic level. The exclusion of the malformation from the bloodstream contributes to the regression of disorders of cerebral and intracardiac blood flow caused by the anatomical and functional characteristics of the malformation itself and its clinical course.

The experience of using the method of 3D design and prototyping is examplified in a clinical case of surgical treatment of a six-year-old patient with kyphoscoliotic deformity of the spine due to congenital malformation of the L1 vertebra. At the stage of diagnostics and preoperative preparation, a created model of the deformed spine was used in the form of a breadboard variant made according to the data of spiral X-ray CT on a 3D printer from a plastic polymer material. The use of the created model of the deformed spine made it possible to additionally visualize and touch the pathological object in full size, to really assess the anatomical features and parameters of the interested vertebral segments and the altered spinal canal, which provided significant constructive assistance in planning surgical intervention and its immediate technical implementation.

This thesis is focused on (I) the outcome of reconstructive treatment of peri-implant defects and (II) risk factors for the development of peri-implantitis. Background An increasing number of individuals have dental implant-supported reconstructions. The long-time survival rate of dental implants is good, but complications do occur. Accumulation of bacteria on oral implants and the development of a pathogenic biofilm at the mucosal margin will result in inflammatory responses diagnosed as peri-implant mucositis(PiM). Furthermore, PiM may progress to peri-implantitis (Pi) involving the implant-supporting bone and potentially result in a severe inflammatory process resulting in alveolar bone destruction and consequently implantloss. Currently, Pi is a common clinical complication following implant therapy.The prevalence of peri-implantitis has been reported to be around 20 %. Susceptibility to infections and a history of periodontitis are considered as important risk indicators for peri-implantitis. It seems logical that a past history of periodontitis is linked to an increased risk of peri-implantitis. It is possible that other patient-associated factors such as a smoking habit, and presence of general diseases may also be linked to a higher risk for developing peri-implantitis.Treatment of peri-implantitis is difficult. Non-surgical treatment modalities may not be sufficient to resolve the inflammatory process to obtain healthy conditions.Surgical treatment of peri-implantitis has commonly been employed in clinical practice to obtain access to the implant surface thereby increasing the possibility to effectively decontaminate the implant surfaces.The effectiveness and long-term outcomes of reconstructive surgical treatments of peri-implantitis has been debated. The scientific evidence suggests that regular supportive care is an essential component in order to maintain and secure long-term results following treatment of peri-implantitis. Aims 1. To assess the short-term efficacy of reconstructive surgical treatmentof peri-implantitis (Study I). 2. To analyse risk factors related to the occurrence of peri-implantitis(Study II). 3. To assess the importance of defect configuration on the healing response after reconstructive surgical therapy of peri-implantitis (Study III). 4. To assess the long-term efficacy of reconstructive surgical treatmentof peri-implantitis (Study IV). MethodsFour studies were designed to fulfil the aims: - A single-blinded prospective randomised controlled longitudinal human clinical trial evaluating the clinical and radiographic results of reconstructive surgical treatment of peri-implantitis defects usingeither AB or BDX. - A retrospective analysis of individuals with either peri-implantitis, or presenting with either peri-implant health, or peri-implant mucositis assessing the likelihood that peri-implantitis was associated with a history of systemic disease, a history of periodontitis, and smoking. - A prospective study evaluating if the alveolar bone defect configuration at dental implants diagnosed with peri-implantitisis related to clinical parameters at the time of surgical intervention and if the short- and long-term outcome of surgical intervention of peri-implantitis is dependent on defect configuration at the time of treatment. - A prospective 5-year follow-up of patients treated either with AB or BDX. Results - The success for both surgical reconstructive procedures was limited. Nevertheless, bovine xenograft provided evidence of more radiographic bone fill than AB. Improvements in PD, BOP, and SUP were observed for both treatment modalities -In relation to a diagnosis of peri-implantitis, a high likelihood of comorbidity was expressed in the presence of a history of periodontitis and a medical history of cardiovascular disease - The buccal-lingual width of the alveolar bone crest was explanatory to defect configuration - 4-wall defects and deeper defects demonstrated more radiographic evidence of defect fill - Reconstructive surgical treatment of peri-implant defects may result in successful clinical outcomes, that can be maintained over at least five years - The use of BDX is more predictable than use of harvested bone from the patient (AB) Conclusions The study results suggest that a bovine xenograft provides better radiographic evidence of defect fill than the use of autogenous bone harvested from cortical autologous bone grafts.Treatment with bone grafts to obtain radiographic evidence of defect fill is more predictable at 3- and 4-wall defects than at peri-implantitis bone defects with fewer bone walls.In relation to a diagnosis of peri-implantitis, a high likelihood of comorbidity was found for a history of periodontitis and a history of cardiovascular disease.
