ABSTRACT
A 20-year-old woman using Qing-Dai for about 7â¯years for intractable ulcerative colitis was admitted to the emergency room because of dyspnea and syncope following exertion. The patient was diagnosed with drug-induced pulmonary arterial hypertension (PAH). Discontinuation of Qing-Dai rapidly improved PAH symptoms. The REVEAL 2.0 risk score, which is useful for assessing the severity of PAH and predicting prognosis, improved from high risk (12) to low risk (4) within 10â¯days. Discontinuing long-term use of Qing-Dai can rapidly improve Qing-Dai-induced PAH. Learning objective: Discontinuing the long-term use of Qing-Dai used for treating ulcerative colitis (UC) can rapidly improve Qing-Dai induced pulmonary arterial hypertension (PAH). REVEAL 2.0 risk score in patients who developed PAH due to Qing-Dai was useful for screening PAH in patients taking Qing-Dai for treatment of UC.
ABSTRACT
Level 3 tracheal injury, characterised by complete laceration with oesophageal or mediastinal soft-tissue herniation, is conventionally indicated for surgical repair. We present the case of a woman in her 60s with level 3 tracheal injury in acute coronary syndrome who was treated successfully without surgery. Venoarterial extracorporeal membrane oxygenation (ECMO) was introduced during lung-rest management to avoid positive pressure ventilation, and percutaneous coronary angioplasty was performed. Venoarterial ECMO was switched to venovenous ECMO when the haemodynamics improved. The tracheal injury healed spontaneously in 10 days, and ECMO was withdrawn on day 15. The patient made full recovery and was discharged on day 51.
