Does Elective Sternal Plating Combined with Steel Wire Reduce Sternal Complication Rates in Patients with Obesity?

Abstract

In this study, sternal complication rates of sternal closures with steel wire or steel wire combined with titanium plate in patients with obesity that underwent cardiac surgery were investigated. The data of 316 patients that underwent cardiac surgery between May 2018 and October 2021 were analyzed retrospectively; 124 patients withbody mass index (BMI) ≥ 30 kg/m2 were divided into group I, patients whose sternotomy was performed with steel wires, and group II, patients whose sternotomy was performed with steel wire combined with titanium plates. A total of 124 patients with BMI ≥ 30 kg/m2 were divided into group I (n=88 [70.9%]) and group II (n=36 [29.1%]). The rate of male patients was found to be significantly higher in group I, whereas the rate of female patients was significantly higher in group II (P<0.001). BMI values were found to be low in group I and high in group II (P<0.001). The distribution of complications was different in the BMI ≥ 35.00-39.99 kg/m2 and ≥ 40 kg/m2 groups (P=0.003). Development of complications was found to be higher in patients with BMI ≥ 40 kg/m2. Sternal dehiscence was observed in two patients in group I, while no dehiscence was observed in group II. The lower incidence of complications and the absence of non-infectious sternal complications and sternal dehiscence in patients with BMI ≥ 35 kg/m2 that underwent steel wire combined titanium plate sternal closure strengthened the idea that plate-supported sternal closure can prevent sternal complications in high-risk patients.
