RESUMEN
This is a single-center retrospective analysis of 3 patients (mean age, 61 y ± 8.6) who underwent repeat prostatic artery (PA) embolization (PAE; rPAE) because of clinical failure after PAE. Revascularization of the central gland through a recanalized PA was the most frequent pattern observed (5 of 7; 71.4%), followed by revascularization through penile collateral vessels (2 of 7; 28.6%). Technical success during rPAE was achieved in 5 hemiprostates (83.3%). Clinical success at 6 months after rPAE was achieved in 2 of 3 patients (66.6%). Implications of these findings could be valuable to those performing PAE.

PURPOSE: To determine whether intraprocedural C-arm cone-beam CT (CBCT) parenchymal blood volume (PBV) can predict the response of colorectal cancer liver metastases (CRCLM) 2 months after irinotecan drug-eluting bead (DEBIRI) chemoembolization. MATERIALS AND METHODS: This single-center observational study was compliant with the Helsinki Declaration and approved by our institutional review board. Thirty-four consecutive CRCLM patients referred for DEBIRI chemoembolization were enrolled between March 2015 and December 2016. Tumor size was assessed at baseline and 2 months after DEBIRI chemoembolization by multidetector CT (Response Evaluation Criteria in Solid Tumors RECIST 1.0), and PBV was measured before and after DEBIRI chemoembolization. Two independent readers reviewed all data. We determined the potential correlation (Spearman's rank correlation) between intraprocedural PBV values and tumor response at 2 months. The relationship between tumor response and PBV was studied using a mixed model. A logistic regression model was applied to study the relationship between patient "Responder/Non-responder" and PBV. RESULTS: There was a strong correlation between baseline PBV or the percent change of PBV and the 2-month tumor response (rho = - 0.8587 (p = 0.00001) and rho = 0.8027 (p = 0.00001), respectively). The mixed model showed that an increase of 1 ml/1000 ml in PBV of a tumor before DEBIRI chemoembolization led to a 0.54 mm decrease in diameter (p < 0.005). A 1% decrease in PBV after DEBIRI chemoembolization resulted in tumor shrinkage of 0.75 mm (p < 0.005). The logistic regression model showed that patients with a 1% smaller mean decrease of PBV after DEBIRI chemoembolization had a 10% lower likelihood of achieving disease control (OR = 0.9, 95% confidence interval (CI) = 0.81-1; p = 0.0493). CONCLUSION: Intraprocedural PBV may predict tumor response to DEBIRI chemoembolization. KEY POINTS: ⢠There is a strong relationship between the parenchymal blood volume (PBV) of colorectal liver metastases before DEBIRI chemoembolization and tumor response at 2 months. ⢠Higher PBV values before DEBIRI chemoembolization correlate with greater tumor shrinkage, but only if the PBV decreases by more than 70% after DEBIRI chemoembolization. ⢠Each increase of 1% in the mean decrease of PBV after DEBIRI chemoembolization resulted in a 10% lower likelihood of achieving disease control (OR = 0.9, 95% confidence interval (CI) = 0.81-1; p = 0.0493).

PURPOSE: This study aimed to estimate the accuracy of dual-phase C-arm cone beam computed tomography (CBCT) for the detection of colorectal cancer liver metastases, as compared with multidetector computed tomography (MDCT). MATERIALS AND METHODS: Between March 2014 and December 2016, 49 consecutive patients referred for intra-arterial treatment for colorectal cancer liver metastases were enrolled in a single-center observational study. All patients were examined with MDCT and with dual-phase C-arm cone beam computed tomography performed after iodine injection in the proper hepatic artery before intra-arterial treatment. Two blinded observers independently reviewed all examinations. Diagnostic accuracy was determined using both a six-cell matrix method and a "worst-case scenario." RESULTS: Readers identified at MDCT 264 colorectal liver metastases and 43 other liver lesions. The early and late arterial phase showed 240 and 277 liver lesions respectively. A certainty of the diagnosis was obtained in 63% and 85% at the early (EAP) and late arterial phase (LAP), respectively. Streak artifacts or liver segment truncation, or inadequate enhancement was responsible for the inability to see or to correctly adjudicate a lesion to a diagnosis in 27% and 15% of the cases at the EAP and LAP. The "worst-case scenario" yielded a Se and Sp of 58% and 51%, respectively, at EAP and 84% and 70%, respectively, at LAP. CONCLUSION: On CBCT, EAP showed limited accuracy. LAP provided the best tumor detectability. KEY POINTS: ⢠The early arterial phase (EAP) yielded poor accuracy: Se = 58% and Sp = 51% (p < 0.0001). ⢠The late arterial phase (LAP) phase yielded good accuracy: Se = 84% and Se = 70% (p = 0.02). ⢠The probability of a correct diagnosis at the EAP was 60%.

Image-guided thermal ablation is a well-established locoregional technique for the treatment of hepatocellular carcinoma (HCC). HCC surveillance programs have led to an increase in the number of patients diagnosed at an early stage of the disease who are eligible for thermal ablation. Tumor response is assessed on imaging and requires extensive follow-up; thus, radiologists play a key role in defining the technical success and efficacy of treatment as well as identifying progressive disease. Although they are rare, complications, such as secondary infections, must also be identified. Several contrast-enhanced imaging techniques can be used at different postprocedural timepoints but magnetic resonance imaging (MRI) and computed tomography (CT), which allow both liver-centered and whole-body imaging are the cornerstones of follow-up. This review describes the imaging features of HCC following thermal ablation. After describing the basic technical elements of follow-up imaging, imaging findings are divided into three groups: normal and expected features (the good), abnormal features, uncontrolled disease, and complications (the bad), and atypical or rare presentations (the ugly).

OBJECTIVES/BACKGROUND: Sleep may be affected by traumatic experiences leading to an increased risk of poor quality of life and daily functioning. However, studies related to sleep habits and problems in conflict-affected areas are still sparse. The present study attended to describe sleep habits, estimate the prevalence rate of sleep disturbances, and identify associated factors in the Gaza strip. PATIENTS/METHODS: A population-based cross-sectional study including 1458 Palestinian adults aged ≥18 years living in the Gaza strip was carried out during the period between 18 February and March 31, 2022. An electronic survey through the free-of-charge Google Forms tool was used for data collection. A range of self-report measures related to sleep, mood, and subjective quality of life were used: the Pittsburgh Sleep Quality Index (PSQI), the World Health Organisation-Five Well-Being Index (WHO-5), the Epworth Sleepiness Scale (ESS), and the Patient Health Questionnaire (PHQ)-9. RESULTS: Three out of five of participants (n = 882, 60.5%) were females and the mean age was 34.8 ± 12.77 years. More than one-third of participants (n = 556, 38.1%) had poor well-being as assessed by the WHO-5 and 108 (7.4%) had a PHQ-9 score ≥ 20 indicating severe depression. The prevalence of poor sleep quality was 52.8% when defined as PSQI ≥ 6 and 30.5% when defined as PSQI ≥ 8. The prevalence of excessive daytime sleepiness (EDS), short sleep duration, severe depression, and poor well-being were 43.6%, 26.4%, 7.1%, and 38.1% respectively. Women and the youngest participants reached the highest prevalence rates for sleep and mood disturbance as well as for daytime dysfunction. Using multivariate binary logistic regression analysis, severe depression, being divorced, a history of psychological disease, poor well-being and previous war injuries were identified as the strongest predictors of poor sleep quality. CONCLUSION: Poor sleep quality, EDS, severe depression, and poor well-being in our sample were strikingly increased. Females and the youngest participants were the most affected. The conflict-affected situation in the Gaza strip combined with the high population density and worsening socio-economic conditions may play an important role in sleep disturbances, mainly because of a high prevalence of mood disturbances. Sleep and mood disturbances also adversely affect the quality of life.

Background: Many individuals with chronic obstructive pulmonary disease (COPD) report suffering from chronic pain, which affects their quality of life. This study aimed to determine the prevalence, characteristics and impact of chronic pain in patients with COPD, and to explore its possible predictive and aggravating factors. Materials and Methods: It was a cross-sectional study. Male individuals with COPD responded to a questionnaire, including mMRC, CAT, Brief Pain Inventory (BPI) (composed of Worst pain, Pain Severity Score (PSS) and Pain Interference Score (PIS)), and Hospital Anxiety and Depression Scale. Patients were divided into group 1 (G1) with chronic pain, and group 2 (G2) without chronic pain. Results: Sixty eight patients were included. The general prevalence of chronic pain was 72.1% (CI95%:10.7%). The most common site of pain was the chest (54.4%). Analgesics were used in 38.8%. Patients from G1 had more hospital admissions in the past (OR=6.4[1.7-23.4]). Three variables were associated to pain in the multivariate analysis: socio-economic level (OR=4.6[1.1-19.2]), hospital admissions (OR=0.087[0.017-0.45]), and CAT (OR=0.18[0.05-0.72]). Dyspnea was associated to PIS (p<0.005). A correlation was found between PSS and PIS (r=0.73). Six patients (8.8%) retired because of pain. Patients who had CAT≥10 were more in G1 (OR=4.9[1.6-15.7]). CAT was correlated to PIS (r=0.5). G1 demonstrated higher anxiety scores (p<0.05). There was a moderate positive correlation between depression symptoms and PIS (r=0.33). Conclusion: Pain should be systematically assessed in COPD patients, regarding its high prevalence. New guidelines should take into consideration pain management to ameliorate patients' quality of life.
RESUMEN
BACKGROUND: Acute hypercapnic respiratory failure (AHRF) is a common life-threatening event in patients with obesity hypoventilation syndrome (OHS). OBJECTIVES: To study the clinical pattern, noninvasive ventilatory support, as well as the short- and long-term outcomes of patients with OHS admitted in a ward because of AHRF. METHODS: We conducted a retrospective cohort study including all adults with OHS aged ≥ 18 - year - old, admitted in a 90-bed-ward for AHRF. RESULTS: A total of 44 patients were included. Fifteen (34.1%) and 29 (65.9%) patients were diagnosed with malignant OHS (mOHS) and nonmalignant OHS (non-mOHS), respectively, while 36 (81.8%) had coexisting obstructive sleep apnea hypopnea syndrome (OSAHS). Patients with mOHS had a significantly higher rate of heart failure (100% vs. 31%; p < 0.001), chronic renal insufficiency (CRI) (73.3% vs. 41.4%; p = 0.04), and dyslipidemia (66.7% vs. 34.5%; p = 0.04) than those with non-mOHS. The mean forced vital capacity (FVC) in our patients was of 59.5% ± 18.5 of the predicted value, lower than what is usually reported in stable patients with OHS. At hospital admission, more than two-thirds (n = 34, 77.3%) were misdiagnosed as having asthma exacerbation (n = 4, 4.9.1%), chronic obstructive pulmonary disease (COPD) exacerbation (n = 12, 27.3%) and/or heart failure (n = 29, 65.9%). Acute pulmonary oedema (ACPE) (n = 16, 36.4%) and acute viral bronchitis (n = 12, 27.3%) were the main identified causal factors, while no cause could be determined in 5 (11.4%) patients. Noninvasive positive pressure ventilation (NIPPV) using bilevel positive airway pressure (BIPAP) was very highly effective to treat AHRF, with only 2.27% of patients failing the modality. Median overall duration of ventilation was 9 hours per day (1.3-20) and was significantly longer in patients with mOHS than in those with non-mOHS (10 [6-18] vs. 8 [1.3-20], respectively; p = 0.01). Forty two of the forty-three patients discharged alive were treated with BIPAP or continuous positive airway pressure (CPAP) in 26 and 16 patients, respectively. The probability of survival was 90% at 12 months, while the probability of readmission for a new episode of AHRF was 56% at 6 months and 22% at 12 months, respectively. CONCLUSION: AHRF in OHS patients is a life-threatening event which can be successfully and safely treated with BIPAP, with a low long-term mortality even in patients with mOHS.
RESUMEN
INRODUCTION: Smoking and tuberculosis are two major public health issues worldwide, particularly in emerging countries. Currently, the relationship between these two scourges is well established. AIM: Describe the clinical, radiological and progressive features of common pulmonary tuberculosis in smokers. METHODS: Comparative study, carried out at the Pneumology department of the Hédi Chaker in Sfax, Tunisia, including 120 patients hospitalized for common pulmonary tuberculosis from January 2014 to December 2016 and who completed their follow-ups for a minimum period of 2 years . The patients were divided into 2 groups: Group1 (G1) consisting of 60 smoking patients and Group 2 (G2) consisting of 60 non-smoking patients. To assess the severity of radiological lesions, we used the International Labour Organization classification for simple pneumoconiosis and the Brouet classification. RESULTS: The mean age of the patients was comparable in the two groups with a predominance of male for G1 (91%) and female for G2 (70%). The smokers consulted later (113 days versus 60 days (p=0.023). Dyspnea, hemoptysis and chest pain were significantly more frequent in the smokers. The radiological lesions were more serious in smoking group. Bilateral lesions were more observed in smokers (58% vs 25% p = 0.004). A positive association was noted between the extent of radiological lesions, stage 3 and 4 according to the Brouet classification, and smoking status (p <0.001). Similarly for the International Labour Organization classification for simple pneumoconiosis , the radiological lesions were more severe (scores 6 - 15) in the smokers (p <0.001).Smoking was associated with poor adherence (p <0.008), prolonged anti-tuberculosis treatment (p <0.001), delayed RBK negativation in sputum (p <0.001), and more frequent reactivation of tuberculosis (p=0.001). After the diagnosis of CPT, 83% of patients continued to smoke at the same rate and only 7% of patients had quit smoking. CONCLUSION: Smoking worsens CPT by making the clinical picture noisier, radiological lesions more aggressive, negativation of BK in sputum later, and reactivation of CPT more frequent.

Diffuse infiltrate lung diseases (DILDs) are frequent in patients with connective tissue diseases. They can be suggestive of connective tissue diseases or occur during follow-up. Antisynthetase syndrome (ASS) is a complex and heterogeneous connective tissue disease. Antisynthetase antibodies, in particular the anti-Jo1 antibody, are found in patients with this syndrome. The prognosis of ASS is conditioned by the occurrence of DILD and its severity, thus guiding therapeutic management. We here report the case of a 57-year-old female patient presenting with acute febrile DILD revealing ASS. Outcome was favorable under bolus corticosteroids in combination with cyclophosphamide treatment.

PURPOSE: We conducted a prospective study to evaluate a new hemorrhoidal bleeding score (HBS). METHODS: All consecutive patients who had consulted between May 1, 2016 and June 30, 2017 for bleeding hemorrhoidal disease were prospectively assessed at a proctological department. The study was conducted in 2 stages. The first stage assessed the validity of the score on a prospective patient cohort. A second stage assessed the interobserver reproducibility of the score on another prospective cohort. RESULTS: One hundred consecutive patients were studied (57 males; mean age, 49.70 years). A positive association between HBS and surgery indication was found (P<0.001). A cut-off value of the score of 5 (≤5 vs. >5) separated patients from surgical to medical-instrumental treatment with a sensitivity and specificity of 75.00% and 81.25%, respectively. In the multivariate analysis, only HBS was significantly associated with the operative decision (odds ratio, 12.22). Prolapse was no longer significantly associated with the surgical indication. After a mean follow-up after treatment of 7 months, HBS improved statistically significantly (P<0.0001). For the reproducibility of the score, an additional 30 consecutive patients (13 males; mean age, 53.14 years) were enrolled with an excellent agreement between 2 proctologists (kappa=0.983). CONCLUSION: HBS is sensitive, specific, and reproducible. It can assess the severity of hemorrhoidal bleeding. It can discriminate between the most severe surgery-indicated patients and does so in a more efficient way than the Goligher prolapse score. It also allows quantifying the extent of change in hemorrhoidal bleeding after treatment.
RESUMEN
The Coronavirus Disease 2019 (COVID-19) pandemic has displayed heterogeneity in disease manifestations and complications. This case report illustrates a rare issue : the spontaneous pneumomediastinum. A 73-year-old male presented with chills, and respiratory symptoms. A reverse transcriptase polymerase chain reaction (RT-PCR) test- confirmed COVID19. At admission, the patient was in severe respiratory distress. C reactive protein was 54 mg/l (normal: 0-5 mg/l), , troponin were negative, brain natriuretic peptid 55 pg/ml (normal range <100 pg/ml) and D-dimer 700 mcg/l (normal: 0-500 mcg/l). Arterial blood gases showed pH 7.49 (normal: 7.35-7.45), PCO2 33,8 mmHg (normal: 34-46 mmHg) and PO2 56 mmHg (normal: 80-97 mmHg) with 16 liter per minute of oxygen. Computed tomography of the chest (CT chest) showed diffuse groundglass opacities (60-70%) without pulmonary embolism. Diagnosis of acute respiratory distress syndrome (ARDS) was made. Low flow oxygen was provided (Oxygen saturation target ≥ 94%), intermediate dose of low molecular weight heparin and 8mg of dexamethason were administarted daily. On day 10, worsening hemodynamics and blood oxygen levels was noted. CT chest showed moderate bilateral pneumomediastinum, without pneumothorax, persistent groundglass opacities (75%) with early fibrosis elements. The patient recovered with no pulmonary sequelae. This case report encourages health workers to get used with infrequent clinical and radiological manifestations of COVID-19 that is still surprising the world.

PURPOSE: To evaluate the influence of intravesical prostatic protrusion (IPP) on clinical outcomes after prostatic artery embolization (PAE) in patients with lower urinary tract symptoms due to benign prostatic hyperplasia. MATERIALS AND METHODS: All consecutive patients who underwent PAE for lower urinary tract symptoms between January 2017 and January 2019 were retrospectively included. IPP was evaluated on pre-treatment magnetic resonance imaging examination and symptoms were assessed at follow-up consultations using the international prostate symptom score (IPSS) and quality of life (QOL) questionnaire. IPPs were classified as grade 1 (<5mm), grade 2 (5-10mm), or grade 3 (>10mm). RESULTS: A total of 160 consecutive men (mean age 65±7.8 [SD] years; range: 45-89 years), underwent PAE. The mean IPSS was 21±7.3 (SD) (range: 5-35) and prostate volume 87±38 (SD) mL (range: 30-200mL). The IPP grade was 1 for 28 (28/160; 18%), 2 for 52 (52/160; 33%), and 3 for 80 (80/160; 50%) patients. There were no significant differences in IPSS at baseline between the three IPP grades. Patients with severe (grade 3) IPP had a significantly higher reduction in IPSS than those with non-severe IPP (grade 1 or 2), with estimated mean reductions of 12±2.5 (SD) (range: -4-28) and 8.3±1.9 (SD) (range: -8-21) (P=0.02), respectively. The mean reduction in the QOL score was 3.0 for grade 3 and 2.0 for grade 1 or 2 IPP (P=0.02). CONCLUSIONS: The degree of IPP does not limit the efficacy of PAE in patients with lower urinary tract symptoms due to benign prostatic hyperplasia.

A 63-year old man was diagnosed with coexisting central (CSA) and obstructive (OSA) sleep apnea, crescendo-decrescendo (CD) periodic breathing (PB), frequent sustained desaturation hypoxemia events related to prolonged hypopnea and mild diurnal hypoventilation. Unilateral diaphragmatic dysfunction (DD) related to diabetic phrenic neuropathy was identified. Magnetic resonance imaging (MRI) scans of the head disclosed frontal-subcortical white matter (WM) lesions, while brainstem MRI found a small punctiform defect in the median area of the pons. Continuous positive airway pressure (CPAP) therapy was ineffective, while a one-month bi-level positive airway pressure (BIPAP) trial provided better outcomes.

PURPOSE: To identify risk factors for local and distant intrahepatic tumor progression after percutaneous ablation of HCC and to compare MWA with monopolar RFA. MATERIALS AND METHODS: Consecutive patients with early or very early HCC who underwent percutaneous monopolar RFA or MWA were included. Factors associated with local and distant tumor progression were identified. Propensity score matching (PSM) was used to limit bias. Statistical analyses were performed with the Kaplan-Meier method using the log-rank test and Cox regression models. RESULTS: One hundred ninety HCC (mean diameter 23 ± 8.6 mm) were treated by RFA (n = 90, 47%) or MWA (n = 100, 53%) in 152 patients (mean age 63 ± 11, 79% men) between 2009 and 2016. The technical success rate was 97.4% (n = 185 HCC). After a median follow-up of 24.6 months (IQR: 9.7-37.2), 43 (23%), HCC showed local tumor progression [after a median of 13.4 months (IQR: 5.8-24.3)] and 91 (63%) patients had distant intrahepatic tumor progression (after a median of 10.4 months (IQR: 5.7-22). The cox model after PSM identified treatment by RFA (HR, 2.89; P = 0.005), HCC size ≥ 30 mm (HR, 3.12; P = 0.007) and vascular contact (HR, 3.43; P = 0.005) as risk factors for local progression. Factors associated with distant intrahepatic progression were HCC ≥ 30 mm (HR, 1.94; P = 0.013), serum AFP > 100 ng/mL (HR, 2.56; p = 0.002), and hepatitis B carrier (HR, 0.51; p = 0.047). CONCLUSION: The rate of local HCC progression was lower after MWA than monopolar RFA, regardless of tumor size and vascular contact. The ablation technique did not influence the risk of distant intrahepatic tumor progression.

PURPOSE: We investigated the clinical effects of bead size in irinotecan-loaded beads chemoembolization (DEBIRI) used for treating liver-dominant colorectal cancer. MATERIALS AND METHODS: Between March 2009 and January 2018, all consecutive patients with colorectal cancer liver metastases referred for DEBIRI at our tertiary center were included in an observational study. Patients were treated exclusively with either 100-mg irinotecan-loaded DC beads of 70-150 µm (small bead group or SB) or 100-300 µm (large bead group or LB) in diameter, in addition to systemic therapy. Liver tumor response rate at 3 months, liver and overall progression-free survival (PFS) and overall survival were estimated. RESULTS: In total, 84 patients with liver-dominant progressive disease underwent 232 DEBIRI sessions. Fifty-four patients were treated in the SB group and 30 patients in the LB group. Liver progression-free rates at 3 months were 86.7% for the LB group and 79.6% for the SB group (NS). Median liver-PFS and overall PFS were, respectively, 7.15 months and 7.15 months for the LB group and 7.65 and 7.55 months for the SB group (NS). Median overall survival was 13.04 months for the LB group and 15.59 months for the SB group (p = 0.04). Specific treatment grade 3 + 4 toxicity occurrence was 5 (17%) in the LB group and 20 (37%) in the SB group. CONCLUSION: No significant difference in patient outcome was observed between DEBIRI bead sizes of 70-150 µm and 100-300 µm. A trend toward higher treatment-specific toxicity was observed with the smaller beads.

AIM: To prospectively evaluate the feasibility and reproducibility of the semiquantitative measurement of the unenhanced area of the prostate by trans-abdominal contrast-enhanced ultrasound (CEUS) performed immediately after prostate artery embolization (PAE) as a prognostic factor of success. METHODS: Thirty-nine patients with PAE were prospectively included. They all underwent pre- and post-PAE trans-abdominal prostate CEUS. Two readers independently evaluated the pre- and post-PAE unenhanced area using a semiquantitative method: unenhanced areas were measured on 3 different slices (basis, middle, and apex) and reported to the whole prostate area. The mean of the three measures was reported semiquantitatively in classes of ten percent and quartiles. We evaluated correlation with clinical success, at 3 months after PAE, defined as a > 25% reduction in the International Prostatic Symptoms Score and a Quality of life < 3. RESULTS: Twenty-three patients who had bilateral PAE were analyzed. Pre-PAE trans-abdominal prostate CEUS showed visible early and marked enhancement of the entire prostate in all patients. After PAE, all patients had a semiquantitatively measured unenhanced area > 25%. The semiquantitative measurement was found to be highly reproducible, with an interclass correlation > 0.8. No correlation was found between the area of unenhanced tissue and clinical success evaluated at 3 months. CONCLUSION: Trans-abdominal prostate CEUS performed early after PAE provides reproducible results and is a valuable tool to evaluate unenhanced areas of the prostate. LEVEL OF EVIDENCE: 3, local non random sample.

Benign Prostatic Hyperplasia (BPH) concerns 50% of men older that 60 Years old and can induce symptoms also earlier. Medical treatment are mostly alpha blockers (AB), 5-alpha réductase inhibitors (5ARI) and phospho-diestérase inhibitors. In case of failure or poor tolerance of drug treatment, surgery can be indicated, after evaluation of the Bladder Outlet Obstruction (BOO), based on urodynamic studies. Endoscopic or open surgery is selected according to the size of the prostate, the expertise of the urologist and patient preference. Surgical treatment is very efficient but carries frequent complications, especially retrograde ejaculation which is very frequent and can compromise fertility and sexual pleasure. Prostatic Artery Embolisation, an outpatient intervention performed by Interventional Radiologists and available in France since 2012 is a new alternative to surgery in case of failure or poor tolerance of medical treatment. It consists in super-selective injection of calibrated micro-particles into both prostatic arteries after femoral artery puncture at the groin. It is safe and efficient and provides appropriate symptomatic improvement BOO related to BPH.
