The TENSION project – a complementary project consists of Action: Clinical testing hypotheses of the treatment of a patient with ischemia or brain haemorrhage in an extended time windowActively follows the TENSION project, which is an international clinical study aimed at testing new, innovative radio interventional performance – thrombectomy in patients with NCMP. The activity extends the original project to include groups of patients with anaurysm and other CNS diseases associated with haemorrhage. Part of the activity is a unique design of a personalised approach to patients with aneurysms in the cranial area, which is based on the principle of mathematical modelling of flow change before and after the introduction of the stent with the possibility of predicting the exact location of the stent introduction with minimising the risk of thrombus in the stent sites.
