A 59-year-old man with myocardial infarction underwent 4-vessel coronary artery bypass grafting. After operation, on the 9th hospital day, fever, dehiscence of the median wound, and pus discharge were observed. Methicillin-resistant Staphylococcus aureus (MRSA) was detected in the wound, and median wound curettage and removal of the sternal bone wire were performed. The infection also involved the substernal area and anterior mediastinum, and a diagnosis of mediastinitis was made. After wound cleansing and antibiotic (vancomycin) administration, inflammatory reactions decreased, and MRSA disappeared from the wound. The wound spontaneously closed, and complete closure required 60 days. On the 75th hospital day, pain from the right shoulder to the neck and numbness in the upper limbs suddenly developed. MRI revealed vertebral body destruction at C5-6, and a diagnosis of cervical osteomyelitis was made. The spinal cord was compressed, and there was a risk of spinal cord injury below the cervical spine. After consultation with orthopedic surgeons, cervical anteroposterior fixation was performed, he improved, and was discharged. We report a patient with MRSA mediastinitis complicated by cervical osteomyelitis who required emergency surgery.

Postsurgical persistent pain, once entrenched, may be resistant to western medical treatments. A 39-year-old man who underwent thoracic repair with blood vessel prosthesis for dissecting aneurysm was presented to our pain clinic due to postoperative persistent pain. He complained his pain mainly around the sternum on which skin became keloid scar and presented tactile allodynia. Initially, we treated the patient with pregabalin, duloxetine and tramadol/acetaminophen fixed-dose combination tablets, leading to no pain relief. Then, we started the treatments with Kampo medicine as well as Yamamoto New Scalp Acupuncture and Unblocking acupuncture. We initially treated him with keishibukuryogan (TJ-23 ; Tsumura ®, Japan) and saikokeishito (TJ-10 ;Tsumura ®, Japan) based on the signs of blood stasis, hypochondrial resistance and pain, but no relief of pain was obtained. Thus, we administered ogikeishigomotsuto in addition to the above Kampo formulas. His pain was gradually decreased with increasing doses of ogi from 3 to 10 g/day and aconite tuber from 1.5 to 6 g/day due to cold sensation, and finally disappeared at 20 months since the start of Kampo treatments. The duration of effectiveness for relieving his pain with acupuncture was gradually increased in proportion to his pain relief. Our experiences suggest that ogikeishigomotsuto with aconite tuber as well as acupuncture may be optimal treatments for the patients with cold sensation suffering from postsurgical persistent pain.
