Endovascular therapy for abdominal pseudoaneurysms: analysis from technical and clinical aspects

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Imaging

Background:

• Abdominal pseudoaneurysms (PSAs) pose significant rupture risks.
• Endovascular therapy is a common treatment modality for PSAs.
• Predictors of treatment success require further clarification.

Purpose of the Study:

• To identify technical and clinical factors influencing endovascular therapy outcomes for abdominal pseudoaneurysms (PSAs).
• To evaluate the impact of different embolization techniques on PSA treatment success.
• To assess the role of clinical parameters, such as shock index and hemoglobin levels, in predicting PSA treatment outcomes.

Main Methods:

• Retrospective analysis of 16 patients undergoing embolization for PSAs.
• Classification of embolization methods into proximal and distal embolization (PDE) and proximal embolization alone (PE).
• Stratification of patients into four groups based on pre-treatment shock index and evaluation of hemoglobin levels.

Main Results:

• No significant differences in success, recurrence, or complication rates between PDE and PE methods.
• A statistically significant correlation was observed between shock index grades and treatment outcomes (P<0.05).
• Hemoglobin levels did not show a statistically significant difference in relation to outcomes.

Conclusions:

• Embolization technique does not appear to influence PSA treatment outcomes.
• Shock index serves as a potential simple predictor of clinical outcomes in PSA patients.
• Prompt endovascular treatment of PSAs is crucial to prevent rupture, irrespective of the specific embolic method used.
