One-Stage Nerve Repair for Post-Ganglionic Brachial Plexus Injury by Using Ipsilateral Ruptured Ulnar Nerve as a Donor for Axillary Artery Rupture with Open Wound.

Open axillary arterial injury is life-threatening, and upper-extremity reperfusion must be performed within approximately 6 h. We present the case of a patient who underwent reperfusion of the upper limb and nerve reconstruction of the post-ganglionic brachial plexus injury in one stage while maintaining stable vital signs. The injury was an avulsion with no fracture.

Intuitive operability evaluation of surgical robot using brain activity measurement to determine immersive reality.

Surgical robots have improved considerably in recent years, but intuitive operability, which represents user inter-operability, has not been quantitatively evaluated. Therefore, for design of a robot with intuitive operability, we propose a method to measure brain activity to determine intuitive operability. The objective of this paper is to determine the master configuration against the monitor that allows users to perceive the manipulator as part of their own body.

Palliative surgery for malignant mediastinal tumor invading the superior vena cava and right atrium.

Intra-atrial extension of a superior vena cava (SVC) tumor is rare and it is associated with high mortality rates. An 80-year-old woman presented with malignant mediastinal tumor invading the superior vena cava and right atrium. The unresectable tumor caused uncontrolled SVC syndrome and led to the risk of pulmonary artery tumor thrombosis.
