Endoscopic Craniosynostosis Repair

Antifibrinolytics Are Not Associated With Reduced Blood Loss in Minimally-Invasive Endoscopic-Assisted Craniectomy for Repair of Single-Suture Craniosynostosis

ABSTRACT

Minimally-invasive endoscopic-assisted craniectomy (EAC) achieves similar functional and cosmetic outcomes, whereas reducing morbidity risk that is often associated with complex cranial vault reconstruction. Antifibrinolytics (AF) usage to limit blood loss and transfusion requirements during complex cranial vault reconstruction has been studied extensively; however, studies are limited for AF therapy in EAC. The aim of this single-center retrospective observational cohort pilot study was to evaluate whether the use of AF was associated with reduced blood loss in infants undergoing EAC. The authors hypothesized that there would be no difference in blood loss between patients who received AF and those that did not receive AF during EAC. Non-syndromic patients who underwent single-suture EAC were retrospectively evaluated. Primary outcome measure was intraoperative calculated blood loss (mL/kg). Secondary outcome measures included perioperative red blood cells transfusion volumes, number of blood donor exposures, and pediatric intensive care unit and total hospital length of stay. Study cohort demographic and outcome data were analyzed; Fisher exact test was used for categorical data, Student t test was used for continuous data. A P value of < 0.05 was considered statistically significant. Forty-nine EAC patients were included in the study with 34 patients in the AF cohort and 15 patients in the non-AF cohort. There were no significant differences in demographics between the 2 groups. Additionally, there was no significant difference in intraoperative calculated blood loss or any secondary outcome measure. In our single-suture EAC study cohorts, AF administration was not associated with a decrease in blood loss when compared to those that did not receive AF therapy.

Anesthesia for Innovative Pediatric Surgical Procedures

Over the past few decades, there have been many advances in pediatric surgery, some using new devices (eg, VEPTR, MAGEC rods) and others using less invasive approaches (eg, Nuss procedure, endoscopic cranial suture release, minimally invasive tethered cord release). Although many of these procedures were initially met with caution or skepticism, continued experience over the past few decades has shown that these procedures are safe and effective. This article reviews the anesthetic considerations for these conditions and procedures.

Treatment of Osteomyelitic Bone Following Cranial Vault Reconstruction With Delayed Reimplantation of Sterilized Autologous Bone: A Novel Technique for Cranial Reconstruction in the Pediatric Patient

ABSTRACT

Craniosynostosis, a deformity of the skull caused by premature fusion of ≥1 cranial sutures, is treated surgically via endoscopic approaches or cranial vault remodeling. Postoperative infection is rare. Management of postoperative surgical site infections often involves culture-directed intravenous antibiotics and debridement, with removal of osteomyelitic bone and hardware in refractory cases. Removal of autologous bone in a pediatric patient presents a reconstructive challenge, as alloplastic options are not optimal in a growing child, especially in the setting of infection. Moreover, infants and small children have limited autologous bone options for reconstruction. We present our case of a young child who developed an infectious complication following cranial vault remodeling. The patient's demographic information, clinical presentation and postoperative course, radiologic features, surgical interventions, and treatment outcomes were reviewed. In our case, autologous osteomyelitic bone underwent tissue processing to eradicate the infection and complete skull reconstruction using the patient's own processed autologous bone was performed in a delayed fashion. The patient is now 1 year postoperative with no recurrence of infection. We present this case as a novel technique to eradicate infection in autologous bone, allowing for delayed autologous cranial reconstruction.
