Optimal treatment of cervical necrotizing fasciitis associated with descending necrotizing mediastinitis.

BACKGROUND

Cervical necrotizing fasciitis (CNF) associated with descending necrotizing mediastinitis (DNM) is a rapidly evolving and life-threatening condition. The aim of this retrospective study was to describe a treatment strategy for CNF with DNM and present a management algorithm for mediastinal extensions of CNF.

METHODS

Patients diagnosed and treated for CNF with DNM over 14 years in a tertiary referral centre were included.

RESULTS

Seventeen adult patients were included. The origin of infection was mainly oropharyngeal. The diagnosis of CNF/DNM was based on clinical and computed tomography findings. All patients underwent cervicotomy for CNF. In ten patients, DNM was located above the carina and could be accessed by a cervical approach. In seven patients, DNM was below the carina, and necessitated sternotomy for anteroinferior mediastinal involvement and posterolateral thoracotomy for posteroinferior mediastinal involvement. All patients received broad-spectrum antibiotics. One patient died 3 days after surgery. The median hospital stay was 30 days. There was no recurrence during long-term follow-up.

CONCLUSION

Prompt diagnosis and early surgical treatment are essential for reducing mortality in CNF/DNM. All patients should undergo extensive cervicotomy. The surgical approach to the mediastinum depends on the supracarinal or infracarinal location of the disease.
