In 17 patients who underwent prostate artery embolization for treatment of lower urinary tract symptoms, the accuracy of preprocedural magnetic resonance (MR) angiography was retrospectively compared with intraprocedural digital subtraction angiography (DSA) in the identification of prostatic artery origin. Of 34 vessels, 26 MR angiography identified origins (76.5%) were confirmed by DSA at the time of embolization. Although image postprocessing is required, the ability of MR angiography to accurately identify prostatic artery origins prior to embolization is useful in treatment planning and can obviate the need for separate computed tomographic angiography, thus reducing both radiation dose and time demand on patients...

PURPOSE: Prostatic artery embolization (PAE) has seen a recent increase in interest as a treatment for men with benign prostatic obstruction (BPO). The appeal of this intervention lies in reported reduction in morbidity and its minimally invasive nature. The purpose of this review is to assess the safety and efficacy of PAE as a new treatment in BPO and explore risks surrounding its performance. METHODS: A review of the literature was performed. Medical databases searched included PubMed, EMBASE, and Cochrane databases, limited to English, peer-reviewed articles...

Pre-prostatic artery embolization (PAE) cone-beam computed tomography (CT) angiograms (n = 31; mean age: 62.4 ± 9.75 years) and conventional CT angiograms (n = 32; mean age: 62.5 ± 7.2 years) were retrospectively compared. Mean signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), radiation exposure, and prostatic artery (PA) identification scores (0-4) for cone-beam CT angiogram and conventional CT angiogram were 33.19 (± 14.31) and 18.13 (± 5.38) (P < .01); 27.42 (± 13.39) and 14.78 (± 4.92) (P < ...

PURPOSE: The goal of this work was to develop phantoms for the optimization of pre-operative computed tomography (CT) scans of the prostate artery, which are used for embolization planning. METHODS: Acrylonitrile butadiene styrene (ABS) pellets were doped with barium sulfate and extruded into filaments suitable for 3D printing on a fused deposition modeling (FDM) printer. Cylinder phantoms were created to evaluate radiopacity as a function of doping percentage. Small-diameter tree phantoms were created to assess their composition and dimensional accuracy...

RATIONALE: Postoperative hemorrhage is a rare complication after laparoscopic radical prostatectomy (LRP), with no case reports of bleeding from the external iliac artery in the literature. PATIENT CONCERNS: A 73-year-old man diagnosed with clinical stage 2c prostate cancer underwent LRP successfully with only approximately 200 mL of intraoperative blood loss. However, his blood pressure dropped from 135/74 to 80/49 mm Hg and his hemoglobin decreased by 66 g/L compared with the preoperative level within 5 hours...

Introduction: Non-surgical minimally invasive treatments are greatly needed for patients with symptomatic benign prostatic hyperplasia (BPH), for whom medical treatment has failed and surgery is contraindicated. This study retrospectively evaluated the efficacy and safety of super-selective prostatic artery embolization (PAE) for BPH, relative to transurethral resection of the prostate (TURP). Aim: To clinically evaluate the efficacy and safety of super-selective PAE for BPH, relative to TURP...

PURPOSE: To evaluate outcome of prostatic artery chemoembolization for patients with prostate cancer (PCa). MATERIALS AND METHODS: This single-center prospective cohort study was conducted between August 2013 and July 2016 in 20 patients with PCa who underwent chemoembolization. Mean patient age was 67.5 years ± 6.4. Gleason score was 6-10, and staging was T2N0M0. Fifteen patients refused prostatectomy and 5 wanted to stop hormonal therapy because of side effects...

A 73-year-old male (height, 156 cm; body weight, 51 kg), without a history of cardiovascular disease or thromboembolic events, was scheduled for transurethral resection of the prostate under spinal anesthesia. Spinal anesthesia was administered with hyperbaric bupivacaine, resulting in an upper anesthetic level of T6. Before surgery, compression stockings were applied to both lower limbs, and the patient was placed in the lithotomy position. Approximately 15 min later, he complained of intolerable chest tightness, followed by tachycardia (heart rate, 110 beats/min) and desaturation (oxygen saturation [SaO2], 90%)...

Twelve patients underwent balloon-occlusion prostatic artery embolization (PAE) at a single center. Bilateral prostatic artery catheterization was achieved in all patients, but unilateral embolization was performed in 1 patient as a result of the presence of a prostatic arteriovenous fistula. Mean International Prostate Symptom Score and quality-of-life score decreased by 15 ± 7 (P < .01) and 4 ± 1 (P < .01) points, respectively, over a mean follow-up period of 22 weeks ± 8. Only self-limiting minor complications were encountered...

PURPOSE: To determine the effects of sublingual glyceryl trinitrate (GTN) on the quality of planning computed tomography (CT) angiography performed prior to prostate artery embolization (PAE). MATERIALS AND METHODS: A retrospective cohort study was performed on patients who had previously undergone CT angiography before a procedure for PAE at our institution. Early CT angiography studies for PAE at our single center had initially been performed without GTN. These were compared to subsequent CT angiography studies that had been performed with GTN, after a previously implemented change in practice...

The Food and Drug Administration (FDA or we) is classifying the prostatic artery embolization device into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the prostatic artery embolization device's classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device...

PURPOSE: To evaluate efficacy and safety of prostate artery embolization (PAE) in urinary catheter-dependent patients with large prostate volumes and high comorbidity scores. MATERIALS AND METHODS: A retrospective single-center review was conducted of 30 patients with urinary retention at time of PAE from November 2014 through February 2017. Mean (range) age was 73.1 years (48-94 y), age-adjusted Charlson comorbidity index was 4.5 (0-10), duration of urinary retention was 63...

Cases: Transarterial embolization of bilateral internal iliac arteries (TAE) is a useful hemostatic method for the management of pelvic fracture patients, but its effects on urinary functions remain unclear. In this study, we evaluated the impact of TAE on lower urinary tract symptoms (LUTS) in 10 pelvic fracture patients. Outcomes: Lower urinary tract symptoms before and after hospitalization were evaluated by International Prostate Symptoms Score, Overactive Bladder Symptoms Score, and Quality Of Life score...

A 59-year-old male with a history of nonobstructive coronary artery disease, diabetes mellitus, hypertension, and prostate cancer presented to the hospital with 1-day history of pleuritic chest pain. Initial workup for acute coronary event was unremarkable. Chest X-ray revealed multiple small radial densities which were linear and hyperdense, consistent with embolization of metallic seeds to the pulmonary circulation. The patient was noted to have had radioactive metallic seeds implanted for prostate cancer 6 months ago...

INTRODUCTION: Gluteal artery aneurysms (GAAs) are rare, accounting for less than 1% of all arterial aneurysms. Most of them are post-traumatic in nature and involve the superior gluteal artery (SGA), while injuries of the inferior gluteal artery (IGA) have been reported less frequently. We report an unusual case of a patient with double saccular GAA of unknown etiology, involving both the SGA and IGA, successfully treated by endovascular embolization. CASE REPORT: A 80-year-old man referred to our hospital complaining of the progressive onset of left buttock pain and swelling exacerbated by sitting position in the last 4 months...
