Eur Radiol: The value of CTA for prostate artery embolization

Prostatic artery embolization (PAE) is a relatively technically difficult operation.

Recently, a study published in the journal European Radiology used objective (not subjective) measurements of preoperative computed tomography angiography (CTA) to evaluate which patient factors would increase the difficulty of PAE surgery, and explored how these factors are predictive The technical difficulty and the usefulness of the radiation dose related to the operation provide imaging support for the prediction of the effect of the operation and the formulation of the plan before the clinical operation.

This study retrospectively included the data of 75 consecutive patients receiving PAE treatment.

The severity of aortic atherosclerosis significantly increased the fluoroscopy time (p = 0.

Table 2 compares the baseline demographic data and predictors of patients with successful bilateral embolization and patients with non-bilateral embolization (unilateral embolization or technical failure).

Preoperative CT angiography reveals that patients with small glands (<40ml), obvious atherosclerosis, and small prostate arteries (<1.
