O15 Secondary stroke lesion growth in the follow-up after endovascular therapy: a prospective longitudinal imaging study
ConclusionsThe phenomenon of lesion growth in the follow-up with microstructural changes is newly described for a high proportion of endovascular treated stroke patients. Of note, the described lesions are predominantly localized in the white matter within the deep watershed zone. Underlying reasons for the secondary injury may be multifactorial, but the association to underlying vascular pathologies directs to a possible connection to disturbed vascular autoregulation functions.

O17 Profile of intracranial artery calcifications and effect on endovascular stroke treatment
ConclusionsIntracranial arterial calcifications within the symptomatic vessel are associated with worse angiographic and functional outcomes. Identification of symptomatic-IAC on baseline imaging may predict need of intracranial stenting and determine their optimal endovascular treatment strategy.ReferencesMaurer CJ, et al.

O23 Mechanical thrombectomy using a modified ADAPT (a direct aspiration first pass technique) in a patient with m1-occlusion and concomitant mca-aneurysm
We present a case in which a patient with a right-sided MCA M1 occlusion (NIHSS 30) and concomitant mediabifurcation aneurysm was fully recanalized (TICI 3) using a modified ADAPT technique, without prior passage of the thrombus as previously described by Turc et al.2. To us, the avoidance of blind aneurysm passage by microwire and microcatheter appears to be a major advantage of the method used. Instead, the aspiration catheter was advanced via a 0.035 Terumo guide wire for proximal stabilization. Thrombus was aspirated with proximally inflated BGC and repeated imaging series up to visualization of the aneurysm neck. Thus...
