Retrospective Analysis of Preoperative Embolization of Spinal Tumors

Retrospective analysis of preoperative embolization of spinal tumors.

BACKGROUND AND PURPOSE Preoperative embolization of primary and metastatic spinal tumors is often performed to decrease intraoperative blood loss and facilitate surgical resection. The purpose of this study was to evaluate the safety of spinal tumor embolization and the variables that may influence intraoperative blood loss. MATERIALS AND METHODS A retrospective analysis of 100 spinal tumor e...

Preoperative transarterial embolization of spinal tumor: embolization techniques and results.

BACKGROUND AND PURPOSE The techniques of preoperative embolization of hypervascular spinal tumors, which has been known to be helpful for completing tumor resection, have not been described in detail. The purpose of this study was to analyze the technique and to evaluate the safety and value of preoperative transarterial embolization of hypervascular spinal tumors. METHODS Eighteen patients w...

Preoperative embolization versus local hemostatic agents in surgery of hypervascular spinal tumors

BACKGROUND Currently, there is no consensus about how to reduce the intraoperative risk of hemorrhage in spinal decompression surgery of hypervascular spinal tumors, such as aggressive hemangioma, multiple myeloma, plasmacytoma, metastasis of renal cell carcinoma. METHODS A retrospective study of 110 patients, operated in our institute was held in the period between 2003 and 2013. There were ...

Pitfalls of preoperative and palliative embolization of cranial tumors

Preoperative Embolization of Extra-axial Hypervascular Tumors with Onyx

OBJECTIVE Preoperative endovascular embolization of intracranial tumors is performed to mitigate anticipated intraoperative blood loss. Although the usage of a wide array of embolic agents, particularly polyvinyl alcohol (PVA), has been described for a variety of tumors, literature detailing the efficacy, safety and complication rates for the usage of Onyx is relatively sparse. MATERIALS AND ...
