Abstract

Purpose

To explore whether a computed tomography angiography (CTA) of the pelvis prior to prostatic artery embolization (PAE) is a beneficial preprocedural planning tool regarding the technical success.

Materials and Methods

Eighty patients with lower urinary tract symptoms treated with PAE were analyzed retrospectively. Forty of these patients received a CTA of the pelvis prior to the procedure (Group A) and were compared to 40 patients who were treated with PAE without prior CT imaging (Group B). Technical success rate, rate of complications, fluoroscopy time (FT), and mean dose area product (DAP) were assessed and compared. All operators performed at least 50 PAE prior to this study. When needed, cone-beam CT (CBCT) was available during intervention.

Results

Mean age was 68.43 ± 8.30 years in Group A and 70.42 ± 7.11 years in Group B (p = 0.252). Mean body mass index was 26.78 ± 3.73 in Group A and 26.85 ± 3.5 in Group B (p = 0.319). Overall technical success was 96.3%. Bilateral PAE was achieved in 60 patients (75.0%) while unilateral PAE was performed in 17 patients (21.3%). Technical failure (no embolization) occurred in two patients of Group A and one patient of Group B. No statistical significance was seen between groups for technical success rate (p = 1.0). Mean DAP was 10,164 × cm2 ± 3944 cGy × cm2 in Group A and 10,039 × cm2 ± 3761 cGy × cm2 in Group B (p = 0.885). Mean FT was 49.27 ± 22.97 min in Group A and 44.32 ± 17.82 min in Group B (p = 0.285). No intervention-related complications during PAE were reported.

Conclusion

With experienced interventionalists and CBCT available during PAE, preprocedural CTA has no additional benefit for technical outcome.
