Fulminant myocarditis is known as a disastrous disease that requires intensive care with mechanical cardiopulmonary support. Percutaneous cardiopulmonary bypass (PCPS), which is referred to as extracorporeal membrane oxygenation, is usually used for fulminant myocarditis. However, in some cases, PCPS may be ineffective because of circulatory insufficiency and could be associated with various severe complications such as multiple organ failure or leg ischemia. In such cases, placement of a ventricular assist device (VAD) is required. A 46-year-old man with fever and severe fatigue was admitted to a local hospital and diagnosed as having fulminant myocarditis. Although an intra-aortic balloon pump and PCPS were introduced, cardiac function was not recovered, causing multiple organ failure and leg ischemia. Hence, he was transferred to our hospital for further mechanical support. Transesophageal echocardiography (TEE) revealed severe biventricular cardiac dysfunction, and radiography showed pulmonary edema. His total bilirubin level was 6.9 mg/dl and platelet level was 3,300/μl. Thus, we implanted a biventricular assist device (BiVAD). At 12 days after the implantation, TEE revealed improvement of cardiac function, and blood biochemical examination revealed recovery of multiple organ function. Thereafter, the patient was weaned from the BiVAD successfully. After the operation, the patient underwent a long rehabilitation. He was discharged 51 days after the operation, without any neurological or cardiac complication.

BACKGROUND: Mandibular reconstruction is performed after segmental mandibulectomy, and precise repositioning of the condylar head in the temporomandibular fossa is essential for maintaining preoperative occlusion. METHODS: In cases without involvement of soft tissue around the mandibular bone, the autopolymer resin in a soft state is pressed against the lower border of the mandible and buccal and lingual sides of the 3D model on the excised side. After hardening, it is shaved with a carbide bar to make the proximal and distal parts parallel to the resected surface in order to determine the direction of mandibular resection. On the other hand, in cases that require resection of soft tissue around the mandible such as cases of a malignant tumor, right and left mandibular rami of the 3D model are connected with the autopolymer resin to keep the preoperative position between proximal and distal segments before surgical simulation. The device is made to fit the lower border of the anterior mandible and the posterior border of the mandibular ramus. The device has a U-shaped handle so that adaptation of the device will not interfere with the soft tissue to be removed and has holes to be fixed on the mandible with screws. RESULTS: We successfully performed the planned accurate segmental mandibulectomy and the precise repositioning of the condylar head by the device. CONCLUSIONS: The present technique and device that we developed proved to be simple and useful for restoring the preoperative condylar head positioning in the temporomandibular fossa and the precise resection of the mandible.

AAAD (Acute type A aortic dissection) may cause trauma, due to a fall down with LOC (loss of consciousness), which can be missed when the disturbance of consciousness is prolonged. Intraoperative heparinization may result in persistent bleeding, and trauma due to a fall with LOC associated with acute aortic dissection should always be kept in mind. An 81-year-old woman underwent emergency surgery for ruptured AAAD with LOC. Preoperative hemodynamics were unstable and low blood pressure persistent even after release of the cardiac tamponade. The partial arch replacement with brachiocephalic artery reconstruction was performed. Before the chest was closed, a large amount of bloody ascites was noted in abdomen and multiple traumas of the liver were found, resulting in a diagnosis of traumatic liver injury due to a fall with LOC. The patient had liver cirrhosis and coagulation abnormality, and hemostasis was difficult to achieve. The operation was finished with gauze packing and placed ABTHERA® was placed for open abdominal wounds. The abdomen was closed in the second stages. The patient's postoperative course was good, and the patient was transferred for continued rehabilitation.
