A 74-year-old female with history of type 2 diabetes, hypertension, and uterine adenocarcinoma presented for CT-guided lung biopsy that was ultimately complicated by an arterial air embolus requiring intensive care. Systemic air embolism is a very rare event but can be devastating. Prompt recognition can be difficult due to an often-vague presentation but is essential and should be considered upon rapid deterioration of a patient's status following high risk procedures. Hyperbaric oxygen therapy is preferred; however, if this is unavailable, additional treatments are predominately supportive care with 100% supplemental oxygen, rapid volume expansion, and ionotropic medications as needed.

Behçet’s disease is an inflammatory vasculitis with the unique feature of pulmonary artery aneurysms. We describe a patient with Behçet’s disease and pulmonary artery aneurysms who presented with massive hemoptysis treated by coil embolization. Although there was immediate resolution of hemoptysis and improvement in hemodynamic status, 2 months later the patient reported a refractory cough and feeling of foreign body in her throat. Imaging demonstrated partial coil migration into the bronchus and trachea. Although endovascular intervention is the first-line treatment for massive hemoptysis, in patients with Behçet’s disease, active inflammation and chronic steroid use may increase the risk of coil erosion and migration.
