Changes in the levels of inflammatory markers after transthoracic device closure of ventricular septal defects in pediatric patients.

BACKGROUND

Transthoracic device closure of ventricular septal defect (VSD) is widely used in the clinic, especially in China. Changes in inflammatory marker levels after transthoracic device closure of VSD in pediatric patients have not been reported.

METHODS

We retrospectively collected clinical data for 85 pediatric patients in our hospital from September 2017 to January 2018. The patients were divided into two groups according to treatment (device group vs. surgical group). The clinical and experimental data from the two groups were statistically analyzed.

RESULTS

Clinical outcomes were good in all patients without any fatal complications. Similar increasing trends in inflammatory markers (white blood cell (WBC) count, procalcitonin (PCT), C-reactive protein (CRP), and interleukin-6 (IL-6)) were found in the two groups, both of which showed noticeable systemic inflammatory responses. In addition, no significant difference in the postoperative levels of inflammatory markers was observed between these two groups.

CONCLUSIONS

Although transthoracic device closure of VSD seems to be less traumatic and involves a quicker recovery, it also induces a systemic inflammatory response as measured by WBC count and PCT, CRP and IL-6 levels, and the altered trends in inflammatory markers were similar to those of conventional surgery under CPB.
