Cardiopulmonary arrest ( CPA ) due to drowning has an extremely high mortality rate, and very few cases have good neurological outcomes. Severe respiratory failure can occur even after resuscitation. A 66 year old woman with a history of refractory epilepsy had a CPA due to drowning. Approximately 20 min after drowning, she was resuscitated and transported to the hospital, and extracorporeal membrane oxygenation ( ECMO ) was introduced on day two due to continued severe respiratory failure caused by acute respiratory distress syndrome ( ARDS) . After the introduction of ECMO , her respiratory status gradually improved and ECMO was discontinued on day 12. Approximately 6 months after drowning, she visited our hospital for a follow‐up with a cerebral performance category of 1. Since cases of CPA due to drowning with a short drowning time or hypothermia are expected to have good neurological outcomes, the introduction of ECMO should be considered as a treatment for ARDS after resuscitation.

Background Ectopic bronchial artery and non-bronchial systemic arteries may be the culprit vessels of hemoptysis. The main cause of clinical failure of bronchial artery embolization is incomplete embolization caused by the misidentification of the culprit arteries by conventional angiography. Multidetector computed tomography angiography is useful for visualizing the culprit arteries. Case presentation An 82-year-old man was admitted with hemoptysis. Preprocedural multidetector computed tomography angiography revealed an ectopic bronchial artery branching from the right thyrocervical trunk. Superselective embolization of the ectopic bronchial artery was performed using gelatin sponge particles and metallic coils. Hemoptysis was controlled by this procedure without any associated complications. Conclusions Ectopic bronchial arteries originating from the thyrocervical trunk are rare. Preprocedural multidetector computed tomography angiography is useful for visualizing the culprit arteries of hemoptysis, especially if a patient has an ectopic bronchial artery or an ectopic non-bronchial systemic artery.
