Background - Acute mortality rate of stroke in Hungary is significantly higher than in Western Europe, which is likely to be partially attributable to suboptimal treatment. Subjects and methods - We examined the use of acute vascular imaging and mechanical thrombectomy for acute ischaemic stroke patients. We collected data on 20 consecutive patients from Hungarian stroke centres before 31st August 2016. Results - Out of the reported 410 patients, 166 (40.4%) underwent CT angiography and 44 (10.7%) had mechanical thrombectomy. Conclusion - Only about 1/3 of acute ischaemic stroke patients eligible for thrombectomy actually had it. The underlying reasons include long onset-to-door time, low utilization of acute vessel imaging and a limited neuro­intervention capacity needing improvement.

[Aim of the study - In the present study, we report procedural and mid-term functional outcome data on the first 50 neurointerventional treatments of acute ischemic stroke in the Kaposi Mór County Hospital, Kaposvár, Hungary. Materials and methods - Endovascular recanalization of occluded large cervical and intracranial arteries was performed following an unsuccessful intravenous lysis or when intravenous lysis was contraindicated. A control cohort was retrospectively formed by analyzing data of 16 patients who has been unsuccesfully treated with iv. lysis before neurointervention was available in our hospital. Results and conclusion - Recanalization rate was 84% and major complication rate was 2% in the neurointerventional group. Mid-term good functional outcome, defined as mRS 0-2, was achieved in 44% in the neurointerventional and in 13% in the intravenous lysis group, after 11.5 and 39.7 months follow-up period, respectively. Subgroup analysis revealed patient age as the strongest predictive factor of good functional outcome. Our data shows that neurointerventional treatment of acute ischemic stroke gives substantially improved functional outcome, in accordance with the results of the recently published international randomized trials.]

[The possibilities of invasive radiological therapy of deep venous thrombosis and in vitro experimental examination of therapeutic factors affecting the treatment]


[INTRODUCTION - The first part of this paper is an overview on the possibilities of invasive radiology treatment of deep venous thrombosis. In the next part an in vitro experiment is described demonstrating the basics of mechanical and pharmaco-mechanical catheters applied in deep venous thrombosis. MATERIALS AND METHODS - The in vitro haemodinamic model of the iliocaval veins contained a thermostat and an engine responsable for pulsing circulation according to the venous system. We tested the chance of driftage of thrombus in different age according to the state of the collateral system. Thrombectomy was made by mechanical (Simpson-catheter) and pharmaco-mechanical (Pulsespray catheter) ways. The weight of the non-drifted thrombi was measured. RESULTS - All the 16 thrombus were flown while collateral system was closed and none of them were flown while the collateral system was open but the rate of their solubility was different. The efficacy of the thrombus-removal by Simpson catheter was better than by Pulse-spray catheter and fresh thrombus-fragments were more soluble than older ones. CONCLUSION - By this in vitro experiment we opened the way for using mechanical and pharmaco-mechanical catheters in deep venous thrombosis.]
