Introduction: Postoperative cement leakage during Balloon Kyphoplasty (BKP) can lead to serious complications. However, there were no imaging assessment reports to predict the risk of leakage preoperatively. This study investigated whether the risk of cement leakage after BKP could be predicted by preoperative computed tomography (CT) imaging and postoperative intravascular embolization.
Methods: 81 patients underwent BKP for acute phase osteoporotic vertebral fractures between November 2016 and September 2019. Sugita classification was used for fracture classification. Preoperative CT was used to evaluate the presence of vertebral cortical disruption, and postoperative CT was used to evaluate the presence of cement leakage.
Cement leakage was significantly more frequent in the slipped endplate type than other types (p=0.0072).
Results: The cement leakage group (group L) consisted of 23 patients (28.4%). The percentage of group L in patients with vertebral cortical disruption was 35.6%, significantly higher than in patients without disruption (p=0.015). All cement embolization into the perivertebral venous plexus occurred in the slipped endplate type.
Conclusions: Preoperative CT showed that cement leakage was significantly higher in patients with vertebral cortical disruption. The slipped endplate type may be a risk factor for cement embolization into the blood vessels.
