Objetivos:
Valorar la eficiencia de la embolización transarterial preoperatoria en tumores óseos, como técnica para disminuir el sangrado transoperatorio y el tiempo quirúrgico.

Material y métodos:
Se incluyó a un total de 29 pacientes (15 hombres y 14 mujeres) con edades que oscilaban entre los 11 y 72 años. Se identificó un total de 17 tumores malignos: tumor de células gigantes (n = 4), osteosarcoma (n = 4), plasmocitoma (n = 2) y tumores metastásicos (n = 7). Hubo 12 tumores benignos: quiste óseo aneurísmico (n = 8), condroblastoma (n = 2) y fibroma no osificante (n = 2).

Resultado:
La pérdida sanguínea de los tumores malignos osciló entre 100 y 600 ml con una media de 362 ml (16 pacientes). El tiempo quirúrgico fluctuó entre dos y cuatro horas con una media de 2.4 horas. La pérdida sanguínea de los tumores benignos fue de 50 a 300 ml, con una media de 173 ml (11 pacientes). El tiempo quirúrgico varió de 2 a 3 horas, con una media de 2.2 horas. Se obtuvieron resultados equiparables e incluso con menor pérdida sanguínea al compararse con estudios de cohortes, así como de casos y controles.

Conclusiones: La embolización transarterial de tumores óseos es un procedimiento seguro y eficaz que reduce el sangrado transoperatorio y el tiempo quirúrgico regular.

Objective:
To assess the efficiency of preoperative transarterial embolization in bone tumors, as a technique to reduce intraoperative bleeding and surgical time.

Matherial and Method:
A total of 29 patients (15 men and 14 women) with ages ranging from 11 to 72 years were included. 17 malignant tumors: giant cell tumor (n = 4), osteosarcoma (n = 4), plasmacytoma (n = 2), metastatic tumors (n = 7). 12 benign tumors: aneurysmal bone cyst (n = 8), chondroblastoma (n = 2), non-ossifying fibroma (n = 2).

Result:
Blood loss from malignant tumors ranged from 100 to 600 ml with an average of 362 ml (16 patients). The surgical time ranged from 2 to 4 hours with an average of 2.4 hours. Blood loss from benign tumors ranged from 50 to 300 ml, with an average of 173 ml (11 patients). The surgical time ranged between 2 and 3 hours, with an average of 2.2 hours. Achieving comparable results and even decreasing blood loss, when compared with cohort studies, as well as case-control studies.

Conclusions:
Transarterial embolization of bone tumors is a safe and effective procedure, which reduces intraoperative bleeding and standard surgical time.

Key words:
Transarterial embolization.
