To evaluate treatment decision-making based on susceptibility-weighted imaging (SWI) in patients with hemorrhage after thrombolysis.
One hundred and forty-six patients without intracranial hemorrhage on CT after receiving recombinant tissue plasminogen activator (rt-PA) were allocated to two groups: antiplatelets (n=72), who received antiplatelet therapy 24h after rt-PA for 10 days; and non-antiplatelets (n=74), who received no antiplatelet therapy. Twenty-two patients with SWI-detected microbleeds (MBs) or hemorrhagic transformation (HT) in the antiplatelets group (Group A) and 28 with MB or HT in the non-antiplatelets group (Group B) were included in this study.
Sixteen patients had MB and six HT in Group A; 18 had MB, six HT, and four parenchymal hemorrhage (PH) in Group B. National Institutes of Health Stroke Scale (NIHSS) scores at 7 and 14 days and the Modified Rankin Scale (mRS) at 90 days post-rt-PA were significantly lower in Group B than in Group A, duration of hospitalization was significantly shorter, and the favorable outcome rate was higher at 90 days (P<0.05). There were no other significant differences. SWI evaluation at 14 days revealed eight patients with MB, 11 HT, and three PH in Group A; in Group B, 16 had MB, five HT, and one PH, with resolution of hemorrhage in six patients.
Treatment decision-making based on SWI in acute stroke after thrombolysis was validated by the significantly reduced NIHSS score after 7/14 days, improved outcome, and reduced mRS in hemorrhage patients without antiplatelet therapy.
评估溶栓后出血患者基于磁敏感加权成像(SWI)的治疗决策。
146 例接受重组组织型纤溶酶原激活剂(rt-PA)治疗后 CT 未见颅内出血的患者分为两组:抗血小板组(n=72),rt-PA 后 24 小时给予抗血小板治疗 10 天;非抗血小板组(n=74),未给予抗血小板治疗。抗血小板组(A 组)22 例 SWI 显示微出血(MB)或出血性转化(HT),非抗血小板组(B 组)28 例显示 MB 或 HT。
A 组 16 例 MB 伴 6 例 HT,18 例 MB 伴 6 例 HT 伴 4 例脑实质出血(PH);B 组 18 例 MB,6 例 HT,4 例 PH。A 组 NIHSS 评分在第 7 天和第 14 天、第 90 天 mRS 评分显著低于 B 组,住院时间显著缩短,第 90 天时预后良好率更高(P<0.05)。其他无显著差异。SWI 在第 14 天评估时,A 组 8 例 MB 伴 11 例 HT 伴 3 例 PH,B 组 16 例 MB 伴 5 例 HT 伴 1 例 PH,6 例出血吸收。
溶栓后急性卒中患者基于 SWI 的治疗决策得到验证,7/14 天后 NIHSS 评分降低,出血患者预后改善,mRS 评分降低,无抗血小板治疗。
