CR - Complete Recanalization PRIME PubMed | Complete Recanalization May Exert the Most Important Statistical analysis First, all patients were classified into subgroups based on the modalities of hyperacute recanalization therapy of EVT alone, combined EVT and tPA, and tPA alone. A recent analysis has shown that complete (TICI 3) recanalization may mitigate some of the effect of time. Basic informed consent was obtained before endoscopy . A total of 184 patients were included. While several endoscopic dilatation methods have been applied and would be desirable, endoscopic recanalization is very difficult in cases with complete esophageal closure. Administration of issue-plasminogen activator achieved complete recanalization, and his lesion on diffusion-weighted imaging (DWI) disappeared and single photon emission computed tomography showed luxury perfusion.

Spontaneous restoration of the continuity of the lumen of any occluded duct or tube, as with postvasectomy recanalization. A complete recanalization after first-line CA without additional SR passes was achieved in n = 15/30 (50%) of patients with a regular surface compared to n = 3/16 (18.8%) of patients with an irregular phenotype and n = 7/32 (21.9%) of patients where thrombus surface characteristics could not be determined ( p < 0.05). Futile complete recanalization: patients characteristics and its time V-CaTh has the potential to enable integrated, enhanced navigation into the target cerebral artery, which leads to complete recanalization (restoration of blood flow) regardless of the size, location, or firmness of the clots, and without clogging or releasing of clot fragments.
