PurposeVertebral hemangiomas (VH) account for 2-3% of all spinal tumors. The majority is incidentally found on radiographic studies: 1% present with pain and/or neurologic deficits. We report our experience with the multidisciplinary management of aggressive symptomatic thoracic VH by concomitant intraoperative sclerotization with sodium tetradecyl sulfate (STS), vertebroplasty, posterior decompression (with/without fusion) and surgical resection in a hybrid operating room (HR) equipped with a rotational scanner and a radiolucent operating table.MethodsPatients admitted with aggressive spinal VH between 2007 and 2018 were included. Data regarding demographics, presenting symptoms, location of the lesion, preoperative embolization, length of the surgery, estimated blood loss (EBL) as well as follow-up (FU) were retrieved.ResultsFive patients were included (three females, mean age 65 years; range 59-75). Three patients presented with a myelopathy and two mechanical thoracic pain. All patients underwent a single-stage percutaneous sclerotization and vertebroplasty followed by a surgical decompression associated with epidural intralesional injection of STS and subtotal resection of the epidural lesion. Two patients had preoperative embolization. Mean procedural duration was 338 min (range 210-480 min). Four patients had marginal EBL, one patient had 500 ml EBL. Patients had no evidence of lesion recurrence or progression at the end of the follow-up.ConclusionsThe single-stage multimodal management of aggressive symptomatic VH is safe and effective. It allows for a direct intraoperative sclerotherapy combined with maximal tumor resection, resulting in reduced blood loss. The use of STS as a direct intraoperative sclerotizing agent is safe and reliable.
