Prostate artery embolization (PAE) is emerging as a safe and efficacious treatment which approaches benign prostatic obstruction (BPO) from a unique perspective. This brings with it distinct advantages and solutions, which we discuss along with cost, evidence, complications and disadvantages.

PURPOSE: To assess the effectiveness of prostate artery embolization (PAE) in the control of haematuria and in patients with benign prostatic hyperplasia (BPH) and normal upper urinary tracts. SUBJECTS/PATIENTS: Twelve consecutive patients with haematuria were included in the prospective study. All patients had prior imaging and cystoscopy to exclude other causes of haematuria. Patients prostate arteries were embolized with particles (200-500 μm), and they were followed up at 3, 12 and 18 months following the procedure...

PURPOSE: To provide initial data on tumoricidal efficacy of embolization on prostate cancer via histopathologic examination of prostatectomy specimens after embolization. MATERIALS AND METHODS: In this bicentric prospective trial, 12 men with localized prostate cancer underwent radical prostatectomy 6 weeks after prostatic artery embolization (PAE) from October 2016 to May 2017. PAE was performed with the use of 100-μm Embozene microspheres (Boston Scientific, Natick, Massachusetts)...

PURPOSE OF REVIEW: Over the last several years prostate artery embolization (PAE) has been developed as a minimally invasive technique for the treatment of benign prostatic hyperplasia induced lower urinary tract symptoms. This review aims to elucidate the data available on this developing technique and identify areas requiring further investigation. RECENT FINDINGS: Recent studies have demonstrated that PAE is able to deliver excellent clinical outcomes in terms of International Prostate Symptom Score, quality-of-life score, maximum urinary flow rate, post-void residual, and prostate volume reduction...

Lactic acidosis is a commonly observed clinical condition that is associated with a poor prognosis, especially in malignancies. We describe a case of an 81-year-old patient who presented with symptoms of tachypnea and general discomfort. Arterial blood gas analysis showed a high anion gap acidosis with a lactate level of 9.5 mmol/L with respiratory compensation. CT scanning showed no signs of pulmonary embolism or other causes of impaired tissue oxygenation. Despite treatment with sodium bicarbonate, the patient developed an adrenalin-resistant cardiac arrest, most likely caused by the acidosis...

Background: Benign prostatic hyperplasia (BPH) is a prevalent disease associated with lower urinary tract symptoms (LUTS). The standard of care for moderate-to-severe LUTS unresponsive to pharmacological treatment is the transurethral resection of the prostate (TURP). However, this intervention is not exempt from complications. Prostatic artery embolization (PAE) has been described as a new, effective and safe procedure for the treatment of LUTS secondary to BPH. To date, only one clinical trial has been published on the use of PAE for LUTS, but the study was methodologically flawed in terms of safety monitoring...

Leiomyomas can develop in any organ containing smooth muscles. They most commonly occur in the gastrointestinal and the female genital tracts. Leiomyoma of the prostate is a rare, benign tumor. We report 3 cases of rare prostatic leiomyomas. The paucity of literature describing prostatic leiomyoma increases the chance for misdiagnosis. Fewer than 30 cases in the English literature, with none including magnetic resonance imaging, computed tomography (CT), ultrasound, positron emission tomography-CT, and pathological findings together were found...

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...

Interventional Radiology procedures, equipment and techniques as well as image guidance have developed dramatically over the last few decades. The evidence for minimally invasive interventions in vascular and oncology fields is rapidly growing and several procedures are considered the first line management. However, radiation exposure, image guidance and innovative solutions to known anatomical challenges are still lagging behind. Robotic technology and its role in surgery have been developing at a steady speed...

Objective: To study the sources of emboli in patients with pulmonary embolism diagnosed by autopsy, and therefore to provide help in the diagnosis and treatment of thromboembolism. Methods: We retrospectively analyzed the pathology and clinical data of 43 patients with pulmonary embolism diagnosed by autopsy from 1962 to 2012 in Beijing Hospital. Results: In patients with pulmonary embolism diagnosed by autopsy, 32.6% of the emboli came from deep veins of the lower extremities, 9.3% from the renal vein, 9.3% from the prostate sinus, 7...

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...

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...
