Abstract：Objective To explore the assessment of the cerebral vasospasm after Perimesencephalic nonaneurysmal subarachnoid hemorrhage(PNSAH)with iFlow imaging technique.Method The observed group included 60 patients who were diagnosed as PNSAH and 60 subjects with normal hemodynamic served as the control. Time to peak (TTP) of the same-part of the bifurcations of bilateral internal carotid arteries, bifurcations of bilateral middle cerebral arteries, tips of bilateral vertebrobasilar arteries were determined by iFlow software(DSA machine,Siemens)in both the groups.Results The TTP in the tips of bilateral vertebrobasilar arteries(at first-visit angiography) is significantly longer in the observed group than that in the control group (P<0.05). The TTP in tips of bilateral vertebrobasilar arteries, right internal carotid bifurcation and right cerebral middle artery bifurcation was significantly longer in the observed group than that in the control group when the angiography was examined again (P<0.05). The TTP in the tips of bilateral vertebrobasilar arteries was significantly longer when the angiography was examined again than that at first visit angiography in the observed group(P<0.05).Conclusions The vasospasm occurs,especially in the vertebrobasilar arteries in the patients with PNSAH.The iFlow imaging technique is a feasible method to assess the cerebral vasospasm in the patients with PNSAH.
