Iatrogene Liquorfistel als Folge eines SARS-CoV-2-Nasopharyngealabstrichs: Eine seltene Komplikation

Since the beginning of the global COVID-19 (coronavirus disease 2019) pandemic over 16 million swab tests have been performed in Austria alone, most of them nasal swabs. Apart from localized bleeding and abscesses very few data suggest more severe complications. Based on 4 case reports iatrogenic cerebrospinal fluid fistula is shown to be a possible consequence of a nasal swab. It is important not to overlook this rare, yet potentially life-threatening complication if an individual presents with corresponding symptoms.
