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.

Abstract:

The article presents an analysis of the choice of strategy for the treatment of ischemic stroke in the acute period, based on literature review.

Aim: was to develop the concept of effective thromboextraction (TE), based on the evaluation of factors influencing results of reperfusion treatment of ischemic stroke (IS), methods of endovascular restoration of cerebral blood flow

Materials and methods: meta-analysis of 44 sources of domestic and foreign literature is performed. The analysis of factors limiting the effectiveness of various reperfusion approaches and the analysis of modern methods of thrombectomy are performed.

Results: it is established, that SMAT (Solumbra) and PROTECT techniques have an advantage in comparison with aspiration approaches to thrombectomy in reducing the period to full reperfusion; methods with temporary occlusion of the source vessel (BGC) SAVE and PROTECT significantly reduce the risk of stroke spread to new vascular areas of the brain and increase the frequency of successful recanalization.

Conclusion: at present time, the PROTECT is the most effective technique in the frequency of successful recanalization, the degree and speed of achieved reperfusion, as well as in the prevention of distal embolization. Extrapolation of experience and principles from other sections of interventional radiology, development of new methods and strategies of brain reperfusion, depending on the morphology of thromboembolism, its size, localization and extent may contribute to improving results of endovascular treatment of ischemic stroke.
