Sir,Thank you for your comments[1] on our case report.[2] Your concerns are absolutely legitimate. Obviously you have extensive knowledge in quantifying platelet function and percentage inhibition of various clotting components. We surely agree with you that thrombelastography (TEG)-platelet mapping may be a better option than the “Regular TEG” for its assessment of percentage contribution to platelet inhibition of individual agent and overall platelet function. However, there are only limited studies supporting the use of platelet mapping following clopidogrel[3] and the insensitiveness of the “Regular TEG” to aspirin and clopidogrel is not good for prevention of thrombotic events[4], but may not necessarily be bad for guiding the epidural catheter removal as long as it indicates reasonably acceptable clotting function. Also the accessibility to TEG platelet mapping can also be an issue in many medical facilities. The overall platelet function at the point of testing is more important than individual percentage contribution of platelet inhibition by individual agent, though our tests may not detect the unresponsiveness of platelets to aspirin or clopidogrel. We reported this case to document the fact this patient had his epidural catheter safely removed 72 h after he received single dose of dual antiplatelet agents, and the normal TEG and platelet function analysis parameters served two functions: Indicating reasonable safety of catheter removal and as indicators that we did not neglect the bleeding tendency medicolegally. Thanks again for your comments.
