Systemic arterial gas embolism (SAGE) as a complication of bronchoscopic lung biopsy: a case report and systematic literature review

A case of massive subcutaneous emphysema and transient ischemic attack due to argon plasma coagulation following endoscopic pilonidal sinus treatment

Pilonidal sinus is a small hole affecting the skin and subcutaneous tissue, which usually contains hair and skin debris, resulting in the creation of the so-called pilonidal cyst. The endoscopic pilonidal sinus treatment (EPSiT) is a minimally invasive procedure consisting of the removal of hairs and cauterization of the cavity under direct endoscopic vision. In our institution, we used to end this procedure with argon plasma coagulation (APC). Here, we discuss a case of 22-year-old man affected by pilonidal disease, who developed a massive subcutaneous emphysema and suspected transient ischemic attack secondary to gas reabsorption after an EPSiT in which APC was used for the coagulation.

Air embolism after transbronchial lung cryobiopsy: A case report

A 76‐year‐old woman underwent transbronchial lung cryobiopsy (TBLC) and transbronchial lung biopsy (TBLB) for examination of interstitial infiltrates. After the examination, the patient's consciousness became clouded, and head computed tomography showed an air embolus. She was started on 100% oxygen, and her consciousness improved, but she remained hemiplegic on the left side and dysphagic. Vascular air embolism (VAE) is a rare but serious complication. Although cases of VAE have been reported with conventional transbronchial forceps biopsy, cases of VAE after TBLC are quite rare, and thus this case is reported.
