Gallbladder gangrene after percutaneous vertebroplasty,an uncommon presentation of vascular complication: a case report and analysis of the causes

We present a case of an 81-year-old man with gallbladder gangrene after percutaneous vertebroplasty (PV) that was successfully treated via laparoscopic cholecystectomy (LC). The patient underwent multilevel, thoracic PV for painful osteoporotic compression fractures. PV performed at the T6 level was complicated by severe abdominal pain owing to direct embolization of the right T6 segmental artery with penetration of bone cement into the radicular artery beneath the pedicle. Cement leakage, especially arterial embolization of cement into the general circulation, is a known potential complication following PV. Serious complications related to PV augmentation procedures, such as vertebroplasty and kyphoplasty, are rare and most often result from local cement leakage or venous embolization. Combined with this case report, we reviewed the literature regarding the unusual occurrence of direct arterial cement embolization during PV and analyzed the causes to alert clinicians to this potentially rare vascular complication.
