ABSTRACT
Objective To investigate the relationship between the residual forward blood flow and the therapeutic outcome in patients with acute cerebral infarction after arterial thrombolysis treatment. Methods During the period from January 2009 to December 2013 at authors’ hospital, a total of 40 patients with acute anterior circle cerebral infarction were treated with arterial thrombolysis. The clinical data were retrospectively analyzed. The patients were divided into group A (n=23) when residual forward blood flow and/or collateral circulation were presented, and group B (n=17) if no residual forward blood flow and/or collateral circulation were detected. The NIHSS scores and hemorrhagic transformation state were determined 14 days after the thrombolysis treatment, and the results were compared between the two groups. Results In group A, 21 cases (91.3%) showed complete or partial re- canalization of the infracted vessels, and asymptomatic hemorrhagic transformation was seen in one case. The pre-treatment NIHSS score was 12.69 ± 3.88 and the post-treatment NIHSS score was 6.05 ± 3.25. In group B, complete or partial re-canalization of the infracted vessels was seen in 15 cases (88.2%), asymptomatic hemorrhagic transformation was found in one case and symptomatic hemorrhagic transformation occurred in one case, who died of massive cerebral hemorrhage seven hours after the thrombolysis treatment. The pre-treatment NIHSS score was 13.51 ± 4.19 and the post-treatment NIHSS score was 8.68 ± 5.16. The differences between the two groups were statistically significant (P < 0.05). The obvious effect rate in group A and group B was 68.1% and 43.8% respectively, and the effective rate in group A and group B was 86.3% and 56.3% respectively, indicating that the clinical outcome of group A was much better than that of group B. Conclusion The therapeutic effect of arterial thrombolysis for acute cerebral infarction patients is not only closely related to the time window but also to the residual forward blood flow. The more the residual forward blood flow there is, the better the therapeutic result with less risk of hemorrhagic transformation will be.
