Abstract: Aim: was to study the efficacy and functionality of the Yukon Chrome PC stent in clinical practice. Materials and methods: in 2021, a prospective, observational study of the safety, effectiveness of the Yukon Chrome PC stent, as well as its functionality during implantation in clinical practice, was launched on the basis of 25 domestic clinics. The study included 364 patients who underwent implantation of 495 Yukon Chrome PC stents. Mean age of patients was 62,8 years (from 33 to 89 years). Men were 263 (72,3%). The vast majority (82,4%) of patients were diagnosed with acute coronary syndrome (ACS): without ST segment elevation - 180 (49,45%) patients; with ST segment elevation - 120 (32,9%) patients. Unstable angina was verified in 22 (6%) patients. There were 42 (11,5%) patients with stable angina class 2-3. Moderate tortuosity of vessels occurred in 27,7% of cases, while severe tortuosity of vessels occurred in 3,57% of cases. Moderate calcification was noted in 115 (31,5%) patients, severe/massive - in 23 (6,3%) cases. A complex lesion combining severe/moderate calcification and severe/moderate tortuosity of the target artery occurred in 79 (21,7%) patients. Results: technical success of the procedure was achieved in 97,5% of cases. In one patient with severe calcification, the Yukon Chrome PC stent could not be inserted into the affected area. Attempts to implant another stent were also unsuccessful. Depending on the number of implanted stents, the patients were distributed as follows: 3 stents were inplanted in 31 (8,5%) patients; 2 stents - 102 (28%) patients, 1 stent - 231 (63,5%) patients. Bifurcation stenting using a two-stent technique was performed in 69 (19%) patients. Stenting of the left main was performed in 11 (3%) cases. Predilation was performed in 245 (67%) patients; postdilation - in 179 (49%) patients. Conclusion: analysis of hospital results of implantation of Yukon Chrome PC stents indicates good flexibility and deliverability of stents even in patients with moderate and severe sheath calcification. The overall assessment of the functional characteristics of the stent among endovascular surgeons who performed stenting is quite high.
Abstract: Introduction: the main methods for diagnosing cardiac neoplasms, allowing to determine the localization, size, involvement of heart structures, to suggest the nature of the pathological process and to plan treatment tactics, are: echocardiography (EchoCG), contrast multispiral computed coronary angiography (MSCT CAG), magnetic resonance imaging (MRI) and positron emission computed tomography (PET CT). At the same time, any additional information about the pathological process can improve the quality of diagnosis and treatment. So, for example, selective coronary angiography (CAG), which in this case can be performed to clarify the coronary anatomy and exclude concomitant coronary atherosclerosis, in hands of attentive and experienced specialist of endovascular diagnostic and treatment methods can make a significant contribution to understanding the nature of blood supply of heart neoplasm, thereby bringing closer the formulation of the correct diagnosis and, ultimately, improving results of surgical treatment. Aim: was to study the nature of blood supply of heart myxoma based on results of a detailed analysis of data of selective coronary angiography in patients with this pathology. Material and methods: since 2005, 20 patients underwent surgery to remove heart myxoma. The average age of patients was 56,6 + 8,0 (43-74) years. According to data of ultrasound examination, sizes of myxomas ranged from 10 to 46 mm in width and from 15 to 71 mm in length (average size ? 25,6 ? 39,1 mm). In 2/3 of all cases (15 out of 20,75%), the fibrous part of the inter-atrial septum (fossa oval region) was the base of myxomas. In 8 of 20 (40%) cases, tumor prolapse into the left ventricle through structures of the mitral valve was noted in varying degrees. In order to exclude coronary pathology, CAG was performed in 14 cases, in the rest - MSCT CAG. Results: of 14 patients with myxoma who underwent selective coronary angiography, 12 (85,7%) patients had distinct angiographic signs of vascularization. In all 12 cases, the sinus branch participated in the blood supply of myxoma, begins from the right coronary artery (RCA) in 10 cases: in 7 case it begins from proximal segment of the RCA and, in 3 cases, from the posterior-lateral branch (PLB) of the RCA. In one case, the source of blood supply of neoplasm was the sinus branch extending from PLB of dominant (left type) circumflex artery of the left coronary artery (PLB CxA LCA). In one case, the blood supply to the neoplasm involved branches both from the RCA and CxA, mainly from the left atrial branch of CxA. Moreover, in all 12 cases, sinus branch formed two branches: branch of sinus node itself and left atrial branch. It was the left atrial branch that was the source of blood supply of myxoma. Analysis of angiograms in patients with myxoma of LA showed that left atrial branch in terminal section formed a pathological vascularization in the LA projection, accumulating contrast-agent in the capillary phase (MBG 3-4). In addition to newly formed vascularization, lacunae of irregular shape were distinguished, the size of which varied from 2 to 8 mm along the long axis. In 8 cases, hypervascular areas with areas of lacunar accumulation of contrast-agent showed signs of paradoxical mobility and accelerated onset of venous phase. In two cases, there were distinct angiographic signs of arteriovenous shunt. In 2 cases (when the size of the myxoma did not exceed 15-20 mm according to EchoCG and CT), angiographic signs allowing to determine the presence of LA myxoma were not so convincing: there was no lacunar accumulation of contrast-agent; small (up to 10 mm) hypervascular areas were noticed, the capillary network of which stood out against the general background of uniform contrasting impregnation and corresponded to MBG grade 1-2. Conclusion: according to our data, angiographic signs of vascularization of myxomas are detected in most cases with this pathology (85,7%). The source of blood supply, in the overwhelming majority of cases, is branch of coronary artery, which normally supplies the structure of the heart, on which the basement of the pathological neoplasm is located. The aforementioned angiographic signs characteristic of myxomas deserve the attention of specialists in the field of endovascular diagnosis and treatment and should be described in details in protocols of invasive coronary angiography.

Abstract: Introduction: every year in the world, more than 13 millions strokes are recorded, most often (up to 80%) - acute cerebrovascular accidents of ischemic type, in which the cause of cerebral infarction is acute embolic occlusion of intracranial artery. Restoration of cerebral perfusion as early as possible from the onset of the disease can lead to a decrease of infarction zone and an improvement in clinical outcomes of the disease. Case report: a 78-year-old patient was admitted with a clinical picture of acute stroke 90 minutes after onset; after computed tomography was performed, according to generally accepted method, systemic thrombolytic therapy was started. Angiography (occlusion of left middle cerebral artery (MCA) in the M1 segment followed by aspiration and then mechanical thrombectomy showed an «early» bifurcation of middle cerebral artery with a large lateral branch. Occluding thrombus was localized precisely in the area of MCA bifurcation, in branches of equal diameter. After unsuccessful attempts at thrombus extraction using the standard thrombus extraction and aspiration technique, patient underwent thrombus extraction using the original method (we called R-Culotte): simultaneous use of two retrievers positioned in the Culotte style (Culotte - «pants», French, R -retriever, English) in lumen of the bifurcation of middle cerebral artery. Blood flow in MCA was restored to mTICI-3 without complications. After the intervention, there was a rapid positive trend. Patient was discharged on 12th day with minimal neurological deficit. Conclusions: this technique allowed to remove the thrombus and restore antegrade blood flow without complications after a series of unsuccessful attempts using the standard approach. Endovascular treatment of ischemic stroke has opened a new era in the treatment of this formidable disease. The search for new techniques for using existing devices contributes to the development of this promising technique.

Abstract Aim: was to explore clinical efficacy and safety of two distal radial approach (DRA) types in primary percutaneous coronary interventions (PCI) in acute coronary syndrome (ACS) patients. Materials and methods: 113 ACS patients with endovascular procedure that had been performed through DRA - met entry criteria. Standard DRA was performed within anatomic snuffbox in 82 patients (72,6%) and modified - on the dorsal surface of the palm (dorsopalmar type) in 31 patients (27,4%). Approach conversion was performed in 7 patients (6,2%). PCI on syndrome- related artery was performed in 94 patients (83,2%). On completion of PCI and final approach angiography, hemostasis was performed with bandage application for 6 hours. Hemostasis comfort was determined by 10 point verbal descriptor Gaston-Johansson scale. On the 5th-7th day after PCI, all patients underwent visual check, palpation and ultrasound duplex scan (UDS). Results: procedure and fluoroscopy time, X-ray load, hemostasis comfort - didn't depend on DRA type. Examination, palpation, UDS performed on the 5th-7th day after PCI didn't reveal cases of forearm radial artery occlusion (RAO). Subcutaneous forearm hematoma (EASY III - IV) was registered in 3 cases (2,7%). RAO was registered in standard DRA group only in 4 cases (3,5%). There were no cases of access side RAO in dorsopalmar DRA group. Conclusion: DRA modifications for PCI in ACS patients are valuable addition to classic radial approach. Dorsopalmar DRA can be considered as basic approach. References 1. Campeau L. Percutaneous radial artery approach for coronary angiography. Cathet Cardiovasc Diagn. 1989; 16:3-7. 2.

Abstract: Aim: was to perform a retrospective comparative analysis of clinical and angiographic results of primary endovascular treatment of ischemic stroke in patients who had contraindications for adjuvant thrombolytic therapy, and results of applying standard pharmaco-invasive (thrombolysis and thrombus extraction) treatment. Material and methods: angiography was performed in 61 patients. The main criterion for the selection of patients for cerebral angiography according to MSCT-angiography, was a confirmed occlusion of a large intracranial vessel (the internal carotid artery or the middle cerebral artery at M1-2 segment). After MSCT-angiography, in the absence of contraindications, (STT) systemic throbolytic therapy (Alteplaza in the standard dose) was started and patients were sent to an endovascular operation, where selective angiography of the syndrome-responsive artery was performed, followed by an endovascular procedure, according to standard procedure. For endovascular treatment, Penumbra Reperfusion catheters - ACE 68 , were used in combination with 3MAX catheters, or stent-retrievers (Trevo, PRESET, ERIC). In a number of cases, the use of retrievers was supplemented with an assisting thrombus aspiration («Solumbra» method). The criterion for the effectiveness of endovascular treatment was the achievement of blood flow in the syndrome-responsible artery TICI 2b - 3. 6 patients with lesion of distal segments of middle cerebral artery (M3-4) or with no occlusion of large intracranial occlusion were excluded from the study. Results: all 55 patients who received endovascular treatment, retrospectively were divided into two groups depending on the performance of adjuvant STT Group of combined treatment (STT and endovascular procedure (EVP)) included 24 patients; 31 patients were included in the primary EVP group. Conclusions: basing on results of the study it can be supposed that primary endovascular treatment of ischemic stroke without thrombolysis can provide comparable efficacy and safety of treatment.
