Prostatic artery embolization using three-dimensional cone-beam computed tomography - 01/11/20
Highlights |
• | Prostatic artery embolization can be challenging because of anatomical difficulties and individual variations in prostatic arteries. |
• | Three-dimensional cone-beam computed tomography can be used to securely target prostatic arteries during prostatic artery embolization. |
• | Three-dimensional cone-beam computed tomography helps catheterize target vessels in prostatic artery embolization. |
Abstract |
Purpose |
The purpose of this study was to report the use of three-dimensional (3D) cone-beam computed tomography (CBCT) for prostatic artery embolization (PAE) in patients with benign prostatic hypertrophy (BPH).
Materials and methods |
Twenty-three consecutive men who underwent PAE using 3D CBCT from June 2016 to September 2018, were retrospectively included in this observational single-center study. There were 23 men with a mean age of 73±12 (SD) years (range: 52–94years) with moderate to severe lower urinary tract symptoms (mean international prostate symptom score, 21±5.7 [SD]; range: 9–30) due to BPH (mean prostate weight, 100g±63 [SD]; range: 30–250g). PAEs were analyzed with respect to procedure time, fluoroscopy time, technical success, complications and dosimetric indices.
Results |
The mean catheterization time of the prostatic artery from the internal iliac artery was 17.3±12.5 (SD) min (range: 8–57min) on the right side and 23.6±14.9 (SD) min (range: 6–54min) on the left side. A technical success was achieved in 21 patients (21/23; 91%). PAE was bilateral in 14 patients (14/21; 66%) and unilateral in 7 patients (7/21; 33%). No occurrence of non-target embolization was reported. The mean dose area product was 146.7±47.9 (SD) Gy.cm2 (range: 54–254Gy.cm2) and mean cumulative air kerma was 771.4±333.3 (SD) mGy; range: 280–1560 mGy. The mean fluoroscopy time was 42.3±23.1 (SD) min (range: 19.4–118.2min).
Conclusion |
3D CBCT is a useful tool to identify the prostatic arteries and facilitates catheterization of prostatic arteries with an acceptable level of radiation exposure.
