Endovascular therapy for abdominal pseudoaneurysms: analysis from technical and clinical aspects.
OBJECTIVE
To clarify the factors of outcomes by endovascular therapy for abdominal pseudoaneurysm (PSA) from both technical and clinical aspects.


METHODS
Sixteen patients with PSAs underwent embolization. Embolic methods were classified into two groups: proximal and distal embolization (PDE) and proximal embolization alone (PE). The patients were classified into four groups by shock index. Pre-embolization hemoglobin (Hb) level and decrease in Hb level were evaluated. Outcomes were classified into two groups: successful recovery and failure despite successful PSA embolization.


RESULTS
There were no statistical differences in success, recurrence, and complication rate, and outcomes between the two embolic methods. There was a statistically significant correlation between the grades of shock indices and outcomes (P<0.05). There was no statistical difference between the Hb levels and outcomes.


CONCLUSIONS
Outcomes were not dependent on the embolic methods. Shock index reflecting clinical status may be a simple predictor of outcome. PSA should therefore be treated by optimal embolic methods as quickly as possible to avoid rupture.
