Deep cervical and paratracheal drainage for descending necrotizing mediastinitis.

Abstract

Background Descending necrotizing mediastinitis is life-threatening and extends into the deep cervical fascia including the pretracheal, perivascular and retrovisceral, and prevertebral spaces. Deep cervical and paratracheal drainage via a transcervical approach prevents the spread of infection into the deep mediastinum. It is effective for local neck drainage and important in the primary treatment of descending necrotizing mediastinitis. Transthoracic mediastinal drainage is also effective for treating this condition. Methods Nine patients with descending necrotizing mediastinitis were treated by deep cervical and paratracheal drainage via a transcervical approach at our institution from April 2007 to December 2017. Four patients with diagnoses of extensive descending necrotizing mediastinitis had progressive extension of abscesses into the lower mediastinum, below the level of the carina. The other five had localized descending necrotizing mediastinitis with infection in the upper mediastinum above the level of the carina. Results All 9 patients (4 with extensive and 5 with localized descending necrotizing mediastinitis) initially underwent deep cervical and paratracheal drainage via a transcervical approach, and all recovered. Two of the patients with extensive infection required no additional surgical intervention. Conclusions Fluid collections in the deep cervical fascia must be drained urgently. Deep cervical and paratracheal drainage via a transcervical approach effectively controls all types of descending necrotizing mediastinitis, and it is less invasive than transthoracic approaches via thoracotomy. However, a thoracotomy for mediastinal drainage must be considered if infection is not controlled by transcervical drainage. Thoracic surgeons and otolaryngologists must plan efficacious treatment before surgical procedures for descending necrotizing mediastinitis.
