• In a patient who had undergone reconstructive surgery on the subclavian artery and was treated postoperatively with aspirin and dextran 40, a bleeding diathesis developed within 24 hours. This was at first thought to be von Willebrand disease, since the bleeding time was longer than ten minutes; the factor VIII level, 28%; and the activated partial thromboplastin time, 50 seconds (normal 30 to 38). The patient's defect responded to discontinuance of the low-molecular-weight, dextran and aspirin therapy and administration of a cryoprecipitate. Later studies of the coagulation mechanism up to two and one-half months were entirely normal. The postoperative defect therefore was assumed to have been the result of the administration of dextran and aspirin. It is possible that in a similar future case, discontinuance of dextran infusion and administration of a single bolus of 12 bags of cryoprecipitate may be adequate treatment.
