Background: A recent randomized control study(the PATCH trial)found no beneficial effect of platelet concentrate(PC)transfusion on the prognosis of patients with intracerebral hemorrhage(ICH)treated with anti-platelet agents(APAs). However, the trial excluded surgical cases. In this study, we examined the effect of PC on ICH, including patients who received surgical treatment.
Method: A retrospective cohort analysis was performed in 23(11 males, 12 females)of 35 patients diagnosed with ICH and treated with APAs between January 2010 and December 2015 at the Department of Neurosurgery, Yamaguchi University Hospital. Twelve patients were excluded due to the use of anticoagulants or replenishment of coagulation factors.
Results: PC transfusion was administered in 12 cases(PC group)but not administered in 11(non-PC group). Conservative therapy at admission was used in 7 and 9 cases in the PC and non-PC groups, respectively, and none of these cases showed hematoma enlargement during conservative therapy. Surgical treatment was performed in 6 and 2 patients in the PC and non-PC groups, respectively, and hematoma enlargement occurred postoperatively in one patient in each group. Outcomes at 3 months after onset showed no significant difference between the groups(mRS 0-3:6 vs. 5 cases, p=0.34). Patients who received PC had no serious adverse events during hospitalization.
Conclusion: In this study, surgery after PC transfusion was performed without any problems. There was no difference in prognosis between patients who did and did not receive PC. These results suggest that surgery can be performed safely after PC transfusion.
