Do we know when to stop the endovascular stroke treatment?: A case report with flat-detector ct cerebral blood volume study [Endovasküler İnme tedavisini ne zaman durduracağımızı biliyormuyuz? Flat-detektör bt serebral kan volümü çalışması ile yapılan vaka sunumu]

It is important to know when to abort further attempts in endovascular stroke therapy during the perioperative period to prevent potential complications of late recanalization. futile recanalization may be due to infarct growth during endovascular stroke therapy and may contribute to poor outcomes. it is possible to select appropriate cases for endovascular stroke therapy with current neuroimaging modalities; however,it is not feasible to evaluate infarct growth during endovascular stroke procedure. herein we present a case with right middle cerebral artery (mca) occlusion for which three attempts of thrombectomy with a stent retriever failed to recanalize the mca. we aborted further attempts at revascularization after assessment of fdct-cbv,which showed a large mca territory cbv abnormality during procedure,and transferred the patient for decompressive surgery. the measurement of cbv within the neuro-angiography suite is a promising method that may facilitate patient selection for endovascular treatment and may also guide decision making regarding when to abort or to continue further attempts. © 2014 ege university press. all rights reserved.
