摘要

Abstract

Background:

Splenic artery embolization (SAE) has been an effective adjunct to the Non-operative management (NOM) for blunt splenic injury (BSI). However

the optimal embolization techniques are still inconclusive. To further understand the roles of different embolization locations and embolic materials in SAE

we conducted this system review and meta-analyses.

Methods:

Clinical studies related to SAE for adult patients were researched in electronic databases

included PubMed

Embase

ScienceDirect and Google Scholar Search (between October 1991 and March 2013)

and relevant information was extracted. To eliminate the heterogeneity

a sensitivity analysis was conducted on two reduced study sets. Then

the pooled outcomes were compared and the quality assessments were performed using Newcastle-Ottawa Scale (NOS). The SAE success rate

incidences of life-threatening complications of different embolization techniques were compared by χ

test in 1st study set. Associations between different embolization techniques and clinical outcomes were evaluated by fixed-effects model in 2nd study set.

Results:

Twenty-three studies were included in 1st study set. And then

13 of them were excluded

because lack of the necessary details of SAE. The remaining 10 studies comprised 2nd study set

and quality assessments were performed using NOS. In 1st set

the primary success rate is 90.1% and the incidence of life-threatening complications is 20.4%

though the cases which required surgical intervention are very few (6.4%). For different embolization locations

there was no obvious association between primary success rate and embolization location in both 1st and 2nd study sets (

0.05). But in 2nd study set

it indicated that proximal embolization reduced severe complications and complications needed surgical management. As for the embolic materials

the success rate between coil and gelfoam is not significant. However

coil is associated with a lower risk of life-threatening complications

as well as less complications requiring surgical management.

Conclusion:

Different embolization techniques affect the clinical outcomes of SAE. The proximal embolization is the best option due to the less life-threatening complications. For commonly embolic material

coil is superior to gelfoam for fewer severe complications and less further surgery management.
