Pneumomediastinum after arthroscopic shoulder surgery -A case report-

Abstract: An 86-year-old female with a history of right rotator cuff injury was admitted for arthroscopic shoulder surgery under general anesthesia. There were no remarkable immediate postoperative complications. However, while recovering in the general ward, she developed dyspnea with hypoxia. She was immediately treated with oxygen, and antibiotics after pneumomediastinum was confirmed on both chest x-ray and chest computed tomography. Subcutaneous emphysema on either face or neck followed by arthroscopic shoulder sur… Show more

“…The exact pathogenetic mechanism for the entry of the air, in shoulder arthroscopy, is not clearly known. Nevertheless, it can be considered, that the transitional changes of the pressure emerged in the subacromial space throughout the whole invasive procedure, compared to the atmospheric pressure, facilitate the entry of the air through the lateral portals, causing possible injury to the pleura in association with the invasive handlings, thus leading to pneumothorax occurrence [21][22][23]. During the arthroscopic technique, the subacromial space is dilated, due to pressure exerted from the injected fluid with the use of an infusion pump, in order to establish a good field of view and most important an appropriate working space.…”

“…(6) O mecanismo patogênico exato permanece incerto. As possíveis causas são anestesia geral/ locorregional, intubação endotraqueal, o procedimento em si, (5)(6)(7) mobilização precoce (5) e complicações infecciosas após o procedimento. (8) No caso aqui relatado, como em outros casos semelhantes, o pneumomediastino provavelmente estava relacionado com o procedimento.…”

“…Isso permite boa visualização da articulação e, ao mesmo tempo, mantém a pressão intraarticular regular. (7) Quando o power shaver aplica sucção, a pressão no espaço subacromial diminui temporariamente e se torna negativa. Sob essa pressão negativa, o ar pode ficar preso no espaço subacromial.…”
