Role of preoperative embolization for intradural spinal XXXX .

@entity1 @entity279 @entity5 @entity190 @entity16 @entity954
UNASSIGNED: @entity279 ( @entity279 ) are relatively rare @entity5 with a high degree of vascularity. Therapy for symptomatic @entity5 involves total resection when possible. Due to the enriched blood supply of these @entity5 , there is a high risk of significant intraoperative @entity190 , which can lead to perioperative complications. Preoperative embolization of @entity279 has been suggested to reduce @entity190 and operative morbidity, but its use remains controversial. Data on the risks and benefits of preoperative embolization for this @entity5 remains limited. We identified and analyzed all 29 reported cases of preoperative embolization of intradural spinal @entity279 within the literature. There were 18 @entity1 and nine @entity1 , and @entity1 ranged from 24 to 61years of age. Mean @entity5 size was 3.5cm. Cervical and thoracic location was most common, accounting for 48.3% and 20% of cases, respectively. Complications from embolization and surgery were minimal, with no deaths or permanent @entity16 . Minimal @entity954 and excellent rates of gross total resection were reported with preoperative embolization. However, outcomes from microsurgery alone from historical series have similarly reported excellent outcomes. While there is no established standard, preoperative embolization should be reserved for particularly high risk @entity1 with risk of @entity954 .
