 We encountered three cases of thigh hematoma during anticoagulant therapy by unfractionated heparin associated with an IVH catheter. In case 1 and 2, thigh hematoma ipsilateral to the IVH catheter emerged soon after weaning from mechanical ventilaton. In addition to a bleeding tendency, due to anticoagulant therapy, a branch of the femoral vein or artery might be injured on puncturing the femoral vein. Also the mechanical compression on the femoral muscle might be involved. In case 3, thigh hematoma contralateral to the IVH catheter emerged. In additon to some other external force on the muscle, a bleeding tendency might be associated. During anticoagulant therapy, even if the value of APTT is under control, we should be aware of the possibility of any hemorrhage.
