Abstract: Article presents a retrospective analysis of using the modified way experience in removing the occlusive substrate from cerebral vessels in the ischemic stroke acute phase after failed standard thrombectomy. Aim: to study the efficacy and advantages of thrombectomy technique from intracranial arteries in patients with acute ischemic stroke combining a stent-retriever with reperfusion catheter in comparison with the standard stent retriever thromboextraction. Methods: we analyzed 54 hospital charts of patients who had underwent endovascular recanalization of intracranial large vessel occlusion in acute ischemic stroke. Patients were divided into two equal groups, depending on thrombus removal method. Standard stent-retriever thrombectomy with a balloon guide-catheter was performed as the first stage in both groups. In 27 cases (1st group), after standard stent-retriever technique failed, we carried out combination of retriever extraction with distal aspiration and a guiding balloon-catheter. If we couldn’t safely insert stent-retriever into catheter of distal approach (during thrombectomy), we switched to vacuum aspiration from guiding balloon-catheter (vacuum-blocked) and removed stent-retriever, microcatheter and distal approach catheter simultaneously without reducing tension. In 27 patients (2nd group) after standard thrombectomy failed we repeated this technique several times. Results: embolic complications relative risk was 2,249, 95% CI (1,126 - 4,492) and reperfusion mTICI 3 100% versus 74,07% rate was higher in the first group, in comparison with the second group. Other complications and hospital outcomes of disease did not differ between groups. Conclusion: a stent retriever combined with distal aspiration and a simultaneous transition to vacuum-blocked extraction using after an unsuccessful standard thrombectomy increases the efficiency of complete reperfusion by 25%. Its use is 1,8 times safer than standard thrombectomy in terms of embolic complications.
Abstract: Introduction: a case report of successful treatment of an extremely rare pathology (0,27-0,34%) - acute occlusion of both internal carotid arteries (ICA) is presented. Aim: was to show possibilities of endovascular surgery in the diagnosis and treatment of acute ischemic stroke (AIS) in patients with bilateral acute ICA occlusion. Materials and methods: a 38-year-old patient was hospitalized by ambulance with the diagnosis of AIS. Multispiral computed tomography (MSCT) revealed left ICA occlusion in the C2-C5 segment. Selective angiography of ICA was performed: right ICA - non-occlusive thrombosis C2-C3 segments; left ICA - thrombotic occlusion in C1 segment. Results: thrombaspiration was performed from the left ICA and right ICA; full recovery of antegrade cerebral blood flow was achieved in both ICA, according to the modified treatment in cerebral infarction score (mTICI) - 3. Patient was discharged after 28 days. At the time of discharge, the modified Rankin Scale (mRS) score was 3. 6 months after discharge mRS was 1. Conclusions: Selective angiography of both ICA in a patient with AIS enabled to detect right ICA thrombosis not detected by MCT, which in its turn changed the treatment tactics of the patient. Aspiration thromebctomy from both internal carotid arteries allowed to achiev full recovery of antergrade cerebral blood flow of both internal carotid arteries. References 1.

Abstract: Introduction: more than 10 million ischemic strokes are recorded in the world every year - a disease, the mechanism of development of which is associated with impaired blood flow to the brain tissues, mainly due to embolism in intracranial arteries. One of treatment methods of ischemic stroke within the «therapeutic window», in the absence of contraindications, is systemic thrombolytic therapy. Thrombolytic therapy has a number of limitations and contraindications, including ongoing or occurring bleeding of various localization within a period of up to 6 months. Aim: was to evaluate the possibility of performing and the effectiveness of «off-label» simultaneous selective thrombolytic therapy and uterine arteries embolization in a patient with acute ischemic stroke with multiple distal lesions of middle cerebral artery branches against the background of ongoing uterine bleeding. Case report: patient S., 42 years old, was hospitalized to the pulmonary department for bronchial asthma treatment with the aim of preoperative preparation before extirpation of the uterus, against the background of menometrorrhagia. At one of days of hospitalization, patient suffered from acute dysarthria, right-sided hemiparesis. When performing multislice computed tomography and angiography, multiple occlusions were revealed in the distal segments (M3-M4) of the left middle cerebral artery. The patient underwent simultaneous selective thrombolytic therapy of the left middle cerebral artery and uterine artery embolization. Results: in the next few hours of the postoperative period, the patient experienced regression of neurological deficit: symptoms of dysarthria were arrested, almost complete restoration of motor activity in the right extremities, residual slight asymmetry of the face; bleeding from uterine stopped. The patient was discharged on the 16th day with a slight neurological deficit. The follow-up period is 18 months. Neurological status with minor deficits: slight asymmetry of facial muscles; the strength of muscles of right limbs is reduced to 4-4,5 points. Ultrasound: a significant decrease in the size of the uterus and myomatous nodes. Menstrual cycle is restored. Conclusions: a wide range of angiographic instruments and skills of endovascular surgeons made it possible to perform «off-label» simultaneous intervention in a patient with ischemic stroke and multiple distal lesions of branches of the middle cerebral artery against the background of ongoing uterine bleeding and giant myoma. The use of methods of endovascular hemostasis makes it possible to stop bleeding by overcoming contraindications to thrombolytic therapy. The use of thrombolytic therapy within the «therapeutic window» allows regression of neurological deficits in patients with multiple distal cerebral artery lesions. References 1.

Abstract: Aim: was to show possibilities of endovascular methods of treatment in patients with acute ischemic stroke in endovascular operation-room of cardiovascular surgical department. Materials and methods: we present two case reports of treatment of patients with acute ischemic stroke, who were admitted to neurological department during first hours from onset. Patients underwent CT perfusion, CT angiography of cerebral arteries. For blood-flow restoration, patients underwent thrombectomy Results: thrombectomy from occluded artery was successful in both cases, that leaded to better recovery of neurological status. Conclusions: wide application of endovascular techniques for restoration of cerebral blood flow in patients with ischemic stroke in the early hours of the onset of the disease, can lead to a more prosperous clinical outcomes, more rapid and complete recovery of the patient. Important is the presence of specialized personnel with appropriate skills and a wide spectrum of endovascular instruments. References 1. Feigin V.L., Lawes C.M.M., Bennet D.A., Anderson C.A.
