Abstract

Abstract:

Objective

To evaluate the clinial application value of enhanced MRI in the treatment of post-sternotomy mediastinitis.

Methods

The clinical data of 30 patients with post-sternotomy mediastinitis treated in Peking University First Hospital from June 2013 to December 2017 were collected. 15 patients who were admitted after January 2016 were selected as the study group and underwent debridement and negative pressure wound therapy under the guidance of enhanced MRI. 15 patients admitted before January 2016 were used as the control group for empirical debridement. Indicators such as the number of operations and average hospitalization days of the two groups were compared.

Results

The average number of operations in patients with post-sternotomy mediastinitis was 2.8±0.8 in the study group and 3.6±1.0 in the control group (P=0.036); The average length of stay in the study group was 38.4±10.1 days and the control group was 50.4±15.3 days (P=0.028).

Conclusion

Using enhanced MRI to guide the debridement of post-sternotomy mediastinitis can significantly reduce the number of operations and hospital stay, and has high clinical application value.

Key words: Post-sternotomy mediastinitis, Enhanced MRI, Negative pressure wound therapy
