[Perioperative management for total en bloc spondylectomy--the effects of preoperative embolization and hypotensive anesthesia].
We retrospectively evaluated the effects of preoperative embolization and hypotensive anesthesia on total en bloc spondylectomy (TES) for solitary spinal metastases. In ten patients (treatment group), feeding arteries of spinal metastases were embolized preoperatively and controlled hypotensive anesthesia was induced during operation. In other ten patients (control group), these treatments were not applied. Intraoperative blood loss as well as the amount of blood transfused in the treatment group were significantly lower than those in the control group. Moreover, postoperative platelet counts in the treatment group were significantly higher than those in the control group. These findings indicate that embolization of feeding arteries of metastases and hypotensive anesthesia decrease intraoperative blood loss and may prevent postoperative complications in TES.
