Dominant dystrophic epidermolysis bullosa (DDEB) is a rare inherited skin disorder characterized by extreme fragility of the skin and mucosa that poses significant challenges for anesthetic management. Herein, we report a case of a 65-year-old woman with DDEB who underwent a 13-hour surgery for mandibular cancer under general anesthesia. To prevent skin and mucosal injuries, meticulous perioperative strategies were implemented, including the use of barrier films and pressure-relieving pads and avoiding adhesive devices. High-flow nasal cannula oxygenation enabled awake fiberoptic intubation without the need for mask ventilation, minimizing the risk of blister formation and airway trauma. Despite the prolonged duration, no pressure ulcers or new skin injuries developed, other than minor epidermal peeling of the lips. This case demonstrates that comprehensive preoperative planning and intraoperative protection can ensure safe anesthesia in patients with DDEB undergoing long surgical procedures.

A 47-year-old man underwent a double-valve replacement involving aortic valve replacement (AVR) and mitral valve replacement (MVR) and Re-Re-DVR 6 and 8 months, respectively, after an initial DVR because of suspected prosthetic valve endocarditis. Detachment of the prosthetic mitral valve occurred during the early postoperative period, for which the patient again underwent treatment 15 and 21 months after the initial surgery. The operative findings showed that the detachment was caused by a wide cleavage of the aortic-mitral continuity. There were bacteria detected on a blood culture, and his C-reactive protein (CRP) level did not reduce at any time. On the basis of these findings, we suspected nonrheumatic inflammatory disease and started steroid therapy. His CRP level became negative, and further prosthetic mitral valve detachment did not recur.
