Abstract:
Objective To investigate the effect of CT perfusion (CTP) imaging guidance in the treatment of acute cere?bral infarction. Methods Patients (n=200) with acute cerebral infarction who visited our clinic within 6 hours underwent CTP examination and were divided into two groups:penumbra group and non-penumbra group according to their CTP imag?ing (presence of penumbra or not). Recombinant tissue plasminogen activator (rt- PA) was administrated for intravenous thrombolysis in both groups. NIHSS (The NIH Stroke Scale), BI (Barthel Index), mRS (modified Rankin Scores) and hemor?rhagic transformation events of two groups were determined before and after thrombolysis to evaluate its effect and prognosis in these two group. Results Compared with non penumbra group, NIHSS was reduced in penumbra group from 7 days after rt-PA (6.67±3.46 vs 4.76±2.04), and this decrease became obvious at 4 weeks after rt-PA (6.67±3.46 vs 3.68±1.93). Effi?ciency rate at 4 week (60.3%) and good prognosis rate at 3 months(71.7%)were both significantly improved in penumbra group than those in non penumbra group(34.7%,56.8%). Conclusion rt-PA under CTP guidance is effective and safe in the treatment of acute cerebral infarction. The thrombolytic therapy window can be enlarged according to the presence of pen?umbra or not and the bleeding conversion rate remains at low level.
