Background
There has been an anecdotal increase in the incidence of tracheal stenosis that has coincided with the SARS-CoV-2 pandemic.
Case presentation
This is a case series in which we report clinical and pathologic findings of two patients who subsequently developed subglottic tracheal stenosis after having been hospitalized with COVID-19 pneumonia. Histopathologic analysis of tissue from these patients shows features consistent with tissue infiltrated with SARS-CoV-2 virus, namely multinucleated syncytial cells with prominent nucleoli.
Conclusion
Our findings directly implicate SARS-CoV-2 in the pathogenesis of tracheal stenosis.
HighlightsIntersphincteric proctectomy is a seldom used technique in the United States.There is currently minimal literature on the treatment of rectal mucocele.This technique can be applied with less morbidity than current resection technique.
Background
There is a very high mortality associated with a tracheoinnominate artery fistula; however, when patients survive, they often require reconstruction of the eroded tracheal defect after the bleeding has been controlled.
Case presentation
This is the case of an 83-year-old male with a tracheoinnominate artery fistula who was stabilized in the operating room and underwent repair of his trachea. A novel technique of using the thymus gland as a pedicled flap to repair a large tracheal defect was executed after achieving hemostasis. The patient’s defect was repaired successfully following control of the fistula.
Conclusions
We have shown that the thymus gland can be used successfully as a pedicled flap for repair of a tracheal defect in the setting of a tracheoinnominate artery fistula.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
