To educate patients with diabetes mellitus, we use a clinical pathway. Pharmacists hold the chair of instruction on the use of drugs and insulin self-injection during the course of the pathway. Until now, teaching contents have been left to discretion of attending pharmacists. Therefore, we draw up a brochure to set standards for instruction.　　By using this brochure, it has become possible to instruct patients without relying only on the knowledge and experience of pharmacists in charge. Additionally, we have become able to share teaching contents of pharmacists with nurses.　　By publishing the brochure, intervention of pharmacists in the pathway has become smoother. For better and more efficient instruction on the use of drugs in a limited time frame in the clinical pathway, we need to overhaul of the brochure and to develop a method to evaluate patient’s understanding.

The patient was diagnosed with popliteal vein vascular aneurysm by ultrasonography. Case 2: A man in his 60s, was referred to our hospital for treatment of lower extremity swelling and pain. Like Case 1, the male patient was suspected of having deep vein thrombosis and femoral artery aneurysms by ultrasound inspection and also diagnosed with pulmonary thromboembolism based on CT findings. We were able to rescue these two patients by rapid medical cooperation. Ultrasonography was particularly useful for diagnosis and morphological evaluation of blood vessels.
