Abstract

Background

Children with congenital heart disease (CHD) have been reported to be at increased risk of developing scoliosis following cardiac surgery. Previous sample studies have reported that these patients may safely undergo posterior spinal fusion (PSF) with low complication rates. The goal of this study is to provide an updated analysis of the perioperative complication profile for posterior spinal fusion in a large cohort of pediatric patients with CHD, using a nationwide database.

Methods

A retrospective cohort study was conducted using 30-day perioperative outcomes data from the NSQIP-P database. Our inclusion criteria were all pediatric patients who underwent posterior spinal fusion by CPT code. Patients were subdivided into two groups: those with a history of cardiac surgery for CHD and those without. Postoperative complications were classified according to the Clavien-Dindo system. Risk factors were assessed in univariate and multivariate logistic regression analyses, with significance set at p < .05.

Results

Our results included 3,426 pediatric patients (68.2% female, 31.8% male) with a median age at spinal fusion of 13.7 ± 2.87 years. A CHD diagnosis was present in 312 patients, with 128 having had prior cardiac surgery. The overall complication rate was 6.68%, with a 10.9% rate in the prior cardiac surgery cohort (p = .068). The most common overall perioperative complications were unplanned read-mission (3.5%), reoperation (2.6%), and superficial wound dehiscence (2.5%). Patients with a history of cardiac surgery were not at increased risk for postoperative complications; however, blood transfusion (p < .001), bronchopulmonary dysplasia (p < .001), combined bronchopulmonary dysplasia and previous cardiac surgery (p = .004), and a neuromuscular diagnosis (p < .001) were all risk factors for major postoperative complications in this cohort.

Conclusions

Children with scoliosis who have undergone cardiac surgery to address CHD are not at an increased risk of perioperative complications within 30 days of undergoing a posterior spinal fusion. However, patients who underwent cardiac surgery for CHD who also had bronchopulmonary dysplasia or an associated neuromuscular diagnosis are at increased risk for perioperative complications. It is important for pediatric orthopedic spine surgeons to be familiar with an updated profile of potential perioperative obstacles they may face when treating these patients, as seen in a large and representative cohort.
