article 3 Citação(ões) na Scopus Renal pseudoaneurysm after core-needle biopsy of renal allograft successfully managed with superselective embolization(2016) ANTONOPOULOS, Ioannis M.; YAMACAKE, Kleiton Gabriel Ribeiro; TISEO, Bruno C.; CARNEVALE, Francisco C.; JUNIOR, Enio Z.; NAHAS, William C.- Peristomal variceal bleeding treated by coil embolization using a percutaneous transhepatic approach(2016) MACIEL, Macello Jose Sampaio; PEREIRA, Osvaldo Ignacio; LEAL FILHO, Joaquim Mauricio Motta; ZIEMIECKI JUNIOR, Enio; COSME, Susyanne Lavor; SOUZA, Moises Amancio; CARNEVALE, Francisco CesarPeristomal variceal bleeding due to portal hypertension is an entity that has rarely been reported with 3%-4% risk of death. A 68-year-old woman who had undergone a palliative colostomy (colorectal carcinoma) presented with a massive hemorrhage from the colostomy conduit. Considering her oncological status with medial and right hepatic veins thrombosis due to liver metastasis invasion, an emergency transhepatic coil embolization was successfully performed. Standard treatment modality for these cases has not been established. Percutaneous transhepatic coil embolization of varices is a safe and effective choice in patients who present with life threatening bleeding and exhibit contraindications to transjugular intrahepatic portosystemic shunt.
- Virtual reality in interventional radiology education: a systematic review(2021) GELMINI, And Yara Particelli; DUARTE, Márcio Luís; ASSIS, André Moreira de; GUIMARÃES JUNIOR, Josias Bueno; CARNEVALE, Francisco CésarAbstract The aim of this study was to compare virtual reality simulation with other methods of teaching interventional radiology. We searched multiple databases-Cochrane Library; Medline (PubMed); Embase; Trip Medical; Education Resources Information Center; Cumulative Index to Nursing and Allied Health Literature; Scientific Electronic Library Online; and Latin-American and Caribbean Health Sciences Literature-for studies comparing virtual reality simulation and other methods of teaching interventional radiology. This systematic review was performed in accordance with the criteria established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Best Evidence Medical Education (BEME) Collaboration. Eligible studies were evaluated by using the quality indicators provided in the BEME Guide No. 11 and the Kirkpatrick model of training evaluation. After the eligibility and quality criteria had been applied, five randomized clinical trials were included in the review. The Kirkpatrick level of impact varied among the studies evaluated, three studies being classified as level 2B and two being classified as level 4B. Among the studies evaluated, there was a consensus that virtual reality aggregates concepts and is beneficial for the teaching of interventional radiology. Although the use of virtual reality has been shown to be effective for skill acquisition and learning in interventional radiology, there is still a lack of studies evaluating and standardizing the employment of this technology in relation to the numerous procedures that exist within the field of expertise.
- Prostatic artery embolization using reflux-control microcatheter: prospective experience addressing feasibility(2022) ASSIS, Andre Moreira de; KAWAKAMI, Willian Yoshinori; MOREIRA, Airton Mota; CARNEVALE, Francisco CesarPurposeTo evaluate the efficacy and safety of Prostatic Artery Embolization (PAE) using a reflux control microcatheter. Materials and methodsThis is a prospective, single-center investigation that included 10 patients undergoing PAE for treatment of lower urinary tract symptoms (LUTS) attributed to benign prostate hyperplasia (BPH). Baseline, 3-month, and 12-month efficacy endpoints were obtained for all patients and included prostate-specific antigen (PSA), uroflowmetry, pelvic magnetic resonance imaging (MRI), and clinical assessment using the International Prostate Symptom Score (IPSS) questionnaire and the IPSS-Quality of life (QoL) item. Complications were assessed using the Cirse classification system. ResultsTen patients entered statistical analysis and presented with significant LUTS improvement 12 months after PAE, as follows: mean IPSS reduction of 86.6% (2.8 vs. 20.7, - 17.9, P < 0.001), mean QoL reduction of 79.4% (1.1 vs. 5.4, - 4.3, P < 0.001), mean prostatic volume reduction of 38.4% (69.3 cm(3) vs. 112.5 cm(3), - 43.2 cm(3), P < 0.001), mean peak urinary flow (Qmax) increase of 199.4% (19.9 mL/s vs. 6.6 mL/s, + 13.3 mL/s, P = 0.006) and mean PSA reduction of 50.1% (3.0 ng/mL vs. 6.1 ng/mL, - 3.0 ng/mL, P < 0.001). One patient (10%) needed transurethral resection of the prostate (TURP) after PAE due to a ball-valve effect. One microcatheter (10%) needed to be replaced during PAE due to occlusion. Non-target embolization was not observed in the cohort. ConclusionThis initial experience suggests that PAE using a reflux control microcatheter is effective and safe for the treatment of LUTS attributed to BPH.

- Prostatic artery embolization for giant prostatic hyperplasia: a single-center experience(2021) ASSIS, André Moreira de; MOREIRA, Airton Mota; CARNEVALE, Francisco Cesar; LANZ-LUCES, José RamónAbstract Objective: To describe the safety and efficacy of prostatic artery embolization (PAE) in patients with a markedly enlarged prostate. Materials and Methods: This was a retrospective study including 18 consecutive patients (mean age, 74 years) with benign prostatic hyperplasia, all with a prostate volume ≥ 200 cm3, who were enrolled to receive PAE for the treatment of moderate-to-severe lower urinary tract symptoms. Results: The PAE procedure was technically successful in 17 patients (94.4%). During follow-up, clinical failure (defined as an International Prostate Symptom Score [IPSS] ≥ 8) was observed in two (11.1%) of those 18 patients. At 3 months of follow-up, there was significant improvement over baseline in all relevant outcome measures: total IPSS (from 15.7 to 2.9); IPSS quality of life score (from 5.2 to 1.0); prostate specific antigen (from 11.4 to 1.82 ng/mL); peak urinary flow rate (from 7.45 to 18.6 mL/s); prostate volume (from 252.4 to 151.6 cm3); and post-void residual volume (from 143.7 to 28.3 mL)-p < 0.05 for all. Of the 18 patients, one (5.6%) presented detachment of prostate tissue and self-limited hematuria, which did not require specific treatment. Conclusion: In patients with a markedly enlarged prostate, PAE proved to be safe and effective, resulting in significant improvements in clinical, imaging, and urodynamic parameters.
- Advanced image guidance for prostatic artery embolization - a multicenter technical note(2021) CARNEVALE, Francisco Cesar; MCCLURE, Timothy; CADOUR, Farah; VIDAL, Vincent; ASSIS, Andre Moreira de; MOREIRA, Airton Mota; ROCHA, Arthur Diego Dias; REBET, Aya; NUTTING, CharlesBackground Prostatic artery embolization (PAE) is associated with patients' quality of life improvements and limited side effects compared to surgery. However, this procedure remains technically challenging due to complex vasculature, anatomical variations and small arteries, inducing long procedure times and high radiation exposure levels both to patients and medical staff. Moreover, the risk of non-target embolization can lead to relevant complications. In this context, advanced imaging can constitute a solid ally to address these challenges and deliver good clinical outcomes at acceptable radiation levels. Main text This technical note aims to share the consolidated experience of four institutions detailing their optimized workflow using advanced image guidance, discussing variants, and sharing their best practices to reach a consensus standardized imaging workflow for PAE procedure, as well as pre and post-operative imaging. Conclusions This technical note puts forth a consensus optimized imaging workflow and best practices, with the hope of helping drive adoption of the procedure, deliver good clinical outcomes, and minimize radiation dose levels and contrast media injections while making PAE procedures shorter and safer.
- Microvascular lung vessels obstructive thromboinflammatory syndrome in patients with COVID-19: Insights from lung intravascular optical coherence tomography(2023) HAJJAR, Ludhmila Abrahao; ANCONA, Marco B.; KALIL FILHO, Roberto; TRESOLDI, Moreno; CALDAS, Jose Guilherme; MONTI, Giacomo; CARNEVALE, Francisco Cesar; COBELLI, Francesco De; ASSIS, Andre Moreira de; CICERI, Fabio; LANDONI, Giovanni; DIJKSTRA, Jouke; MORONI, Francesco; ABIZAID, Alexandre Antonio Cunha; UNGARETTI, Fernanda Willemann; CARMONA, Maria Jose Carvalho; BACKER, Daniel De; POMPILIO, Carlos Eduardo; JR, Fabio S. de Britto; CAMPOS, Carlos M.; ZANGRILLO, Alberto; MONTORFANO, MatteoBackground Microvascular lung vessels obstructive thromboinflammatory syndrome has been proposed as a possible mechanism of respiratory failure in COVID-19 patients. However, it has only been observed in post-mortem studies and has never been documented in vivo, probably because of a lack of CT scan sensitivity in small pulmonary arteries. The aim of the present study was to assess the safety, tolerability, and diagnostic value of optical coherence tomography (OCT) for the assessment of patients with COVID-19 pneumonia for pulmonary microvascular thromboinflammatory syndrome.Methods The COVID-OCT trial was a multicenter, open-label, prospective, interventional clinical study. Two cohorts of patients were included in the study and underwent pulmonary OCT evaluation. Cohort A consisted of patients with COVID-19 with a negative CT scan for pulmonary thrombosis and elevated thromboinflammatory markers (D-dimer > 10,000 ng/mL or 5,000 < D-dimer < 10,000 ng/mL and one of: C-reactive Protein > 100 mg/dL, IL-6 > 6 pg/mL, or ferritin > 900 ng/L). Cohort B consisted of patients with COVID-19 and a CT scan positive for pulmonary thrombosis. The primary endpoints of the study were: (i) to evaluate the overall safety of OCT investigation in patients with COVID-19 pneumonia, and (ii) to report on the potential value of OCT as a novel diagnostic tool for the diagnosis of microvascular pulmonary thrombosis in COVID-19 patients.Results A total of 13 patients were enrolled. The mean number of OCT runs performed in each patient was 6.1 +/- 2.0, both in ground glass and healthy lung areas, achieving a good evaluation of the distal pulmonary arteries. Overall, OCT runs identified microvascular thrombosis in 8 patients (61.5%): 5 cases of red thrombus, 1 case of white thrombus, and 2 cases of mixed thrombus. In Cohort A, the minimal lumen area was 3.5 +/- 4.6 mm(2), with stenosis of 60.9 +/- 35.9% of the area, and the mean length of thrombus-containing lesions was 5.4 +/- 3.0 mm. In Cohort B, the percentage area obstruction was 92.6 & PLUSMN; 2.6, and the mean thrombus-containing lesion length was 14.1 +/- 13.9 mm. No peri-procedural complications occurred in any of the 13 patients.Conclusion OCT appears to be a safe and accurate method of evaluating the distal pulmonary arteries in hospitalized COVID-19 patients. Here, it enabled the first in vivo documentation of distal pulmonary arterial thrombosis in patients with elevated thromboinflammatory markers, even when their CT angiogram was negative for pulmonary thrombosis.
- The histology of prostate tissue following prostatic artery embolization for the treatment of benign prostatic hyperplasia(2013) CAMARA-LOPES, George; MATTEDI, Romulo; ANTUNES, Alberto A.; CARNEVALE, Francisco C.; CERRI, Giovanni G.; SROUGI, Miguel; ALVES, Venancio A.; LEITE, Katia R. M.Objective: Prostatic artery embolization (PAE) for the treatment of patients with symptomatic benign prostatic hyperplasia (BPH) is believed to be a safe procedure with a low risk of adverse side effects. Artery embolization is a viable treatment option in patients who are refractory to the classic noninvasive treatments. Knowledge of the histological characteristics of prostate tissue following the procedure is still limited. In this study, we describe the microscopic aspects of the prostate following PAE for BPH. Materials and Methods: Two patients underwent transurethral resections of the prostate (TURP) after PAE. Embolizations were performed under local anesthesia with an initial pelvic angiography to evaluate the iliac vessels and the prostate arteries using a 2.8 French microcatheter. The prostate was embolized with 300-500 mu m Microspheres (Embosphere (R)), using complete blood stasis as the end point. The prostate tissues were analyzed histologically to characterize the effects of the embolization. Results: The embolic material within the prostate tissue was easily identified as homogeneous, bright eosin-red spheroids filling the vessel lumens. Ischemic necrosis surrounded or not by chronic inflammatory reactions containing macrophages were considered as a result of the artery embolization. Also, some aspects related to the healing process were observed being fibrotic nodules surrounded by glands with squamous metaplasia of the epithelial lining the most important. In the remaining sections, due to the precocious surgical intervention, the classic findings of BPH were still present with the glandular and stromal hyperplasia associated with nonspecific chronic prostatitis. Conclusions: This is the first description of prostate histology in BPH patients treated by PAE, a new procedure that is being used increasingly as a therapeutic intervention. The recognition of the changes caused by this new modality of treatment has become a very important differential in a chronic granulomatous reaction of the prostate tissue.
- Management and treatment of decompensated hepatic fibrosis and severe refractory Schistosoma mansoni ascites with transjugular intrahepatic portosystemic shunt(2022) SANTO, Maria Cristina Carvalho do Espirito; GRYSCHEK, Ronaldo Cesar Borges; FARIAS, Alberto Queiroz; ANDRAUS, Wellington; CARVALHO, Noemia Barbosa; LEITE, Olavo Henrique Munhoz; CASTRO, Felipe Correa; CERRI, Giovanni Guido; HYPOLITTI, Gustavo Henrique; CARNEVALE, Francisco Cesar; ASSIS, Andre Moreira deThis study aimed to report the first case of a patient with hepatosplenic schistosomiasis mansoni, refractory ascites and portal vein thrombosis treated with a transjugular intrahepatic portosystemic shunt (TIPS), at the Instituto de Radiologia, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil. After the procedure, the patient recovered favorably and progressed with portal pressure reduction and no deterioration of the liver function. Endovascular shunt modification is a conservative medical approach that often helps in reducing symptoms significantly, making it a less invasive and a safer alternative to liver transplantation for the treatment of schistosomiasis with portal hypertension.
