- Infusion of Recombinant Human Tissue Plasminogen Activator Through the Superior Mesenteric Artery in the Treatment of Acute Mesenteric Venous Thrombosis(2011) LEAL FILHO, Joaquim Mauricio da Motta; SANTOS, Aline Cristine Barbosa; CARNEVALE, Francisco Cesar; SOUSA JR., Wilson de Oliveira; GRILLO JR., Luiz Sergio Pereira; CERRI, Giovanni GuidoAcute mesenteric venous thrombosis is an uncommon condition that is usually treated with systemic anticoagulation. Catheter-directed thrombolysis through the superior mesenteric artery may be a viable adjunct to treat this morbid condition. In the present article, we have described a case of superior mesenteric venous thrombosis treated with catheter-directed infusion of tissue plasminogen activator through the superior mesenteric artery.
conferenceObject Prospective study of thromboembolic events after reoperation in permanent artificial cardiac pacing(2018) ALBERTINI, C. M.; SILVA, K. R.; LEAL FILHO, J. M.; MARTINELLI FILHO, M.; COSTA, R.- Quality of Life and Clinical Symptom Improvement Support Prostatic Artery Embolization for Patients with Acute Urinary Retention Caused by Benign Prostatic Hyperplasia(2013) CARNEVALE, Francisco C.; MOTTA-LEAL-FILHO, Joaquim M. da; ANTUNES, Alberto A.; BARONI, Ronaldo H.; MARCELINO, Antonio S. Z.; CERRI, Luciana M. O.; YOSHINAGA, Eduardo M.; CERRI, Giovanni G.; SROUGI, MiguelPurpose: To show that prostatic artery embolization (PAE) improves quality of life (QoL) and lower urinary tract symptoms in patients with acute urinary retention caused by benign prostatic hyperplasia (BPH). Materials and Methods: This was a single-center prospective study of PAE in 11 patients with BPH managed With indwelling. urinary catheters. International Prostate Symptom Score (IPSS), ultrasound, magnetic resonance (MR) imaging, QoL, and urodynamic tests were used. to assess outcomes. Prostate size ranged from 30 to 90 g, and embolizations were performed with 300-500-mu m Embosphere microspheres. Results: The rate of technical success (ie, bilateral PAE) was 75%, and the rate of clinical success (ie, catheter removal and symptom improvement) was 91% (10 of 11 patients). Postembolization syndrome manifested as mild pain in the perineum, retropubic area, and/or urethra. Ten of 11 patients urinated spontaneously after Foley catheter removal 4-25 days after PAE (mean, 12.1 d). No major complications Were observed. Follow-up ranged from 19 to 48 months. than asymptomatic patient, a discrete area of hypoperfusion: suggesting small ischemia of the bladder was observed on 30-day MR imaging follow-up, but the bladder was normal on 90-day MR imaging. After 1 year, mean prostate volume reduction was greater than 30%, symptoms were mild (mean IPSS, 2.8 +/- 2.1; P = .04),. no erectile dysfunction was observed, and QoL,improved significantly (mean , 0.4 +/- 0.5; P = .001) using the paired t test. Conclusions: Patients with severe symptoms and acute urinary retention caused by BPH can be treated Safely by PAE, which improves clinical symptoms and QoL.
- GAUCHO-Trial Genicular Artery Embolization Using Imipenem/Cilastatin vs. Microsphere for Knee Osteoarthritis: A Randomized Controlled Trial(2022) CORREA, Mateus Picada; MOTTA-LEAL-FILHO, Joaquim M.; LUGOKESKI, Ricardo; MEZZOMO, Marcio; LEITE, Lucas RicciGenicular artery embolization (GAE) has emerged as a treatment option to improve quality of life in patients suffering from moderate-to-severe pain refractory to conservative treatment of knee osteoarthritis, with encouraging results. This paper describes the study protocol of a single-center, double-blind, randomized controlled trial designed to evaluate and compare the safety and efficacy of GAE using imipenem/cilastatin vs. microspheres for the treatment of moderate-to-severe pain associated with knee osteoarthritis. We hypothesized that there will be no difference in safety and efficacy outcomes. The study received ethics approval of the institutional review board with number 4.364.391 / CAAE: 37590820.3.0000.5342 and is registered onto the Registro Brasileiro de Ensaios Clinicos (ReBEC), with number RBR-2h5rwgb. Technical success was defined as embolization of at least 1 feeding artery supplying the hyperemic synovium of the knee joint. Primary outcome: clinical success was defined as improvement in symptoms, 50% reduction in Western Ontario and McMaster Universities Osteoarthritis Index pain scores or an increase of at least 10 points in the Knee Injury and Osteoarthritis Outcome Score from baseline to 3 months of follow-up. Secondary outcome: radiological success was defined as significant improvement in the Whole-Organ Magnetic Resonance Imaging Score for knee synovitis considering the embolized areas at 12 months of follow-up after GAE and a reduction in the analgesia or other conservative therapies for knee pain used by the patient at 3 and 12 months of follow-up. Clinical assessments will be performed before GAE, during GAE and at hospital discharge (for Visual Analog Scale of pain), and at 30 days, 3 months, and 12 months after GAE.
- 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.
- Upper extremity deep venous thrombosis and pulmonary embolism after transvenous lead replacement or upgrade procedures(2020) ALBERTINI, Caio Marcos de Moraes; SILVA, Katia Regina da; LIMA, Marta Fernandes; LEAL FILHO, Joaquim Mauricio da Motta; MARTINELLI FILHO, Martino; COSTA, RobertoBackground Venous obstructions are frequent in patients with transvenous leads, although related clinical findings are rarely reported. After lead replacement or upgrade procedures, these lesions are even more frequent, but there is still no evidence to support this observation. Aim To investigate the incidence and possible risk factors for upper extremity deep venous thrombosis (UEDVT) and pulmonary embolism (PE) after lead replacement or upgrade procedures. Methods Prospective cohort carried out between April 2013 and July 2016. Preoperative evaluation included venous ultrasound and pulmonary angiotomography. Diagnostic exams were repeated postoperatively to detect the study outcomes. Multivariate logistic regression models were used to identify prognostic factors. Results Among the 84 patients included, 44 (52.4%) were female and mean age was 59.3 +/- 15.2 years. Lead malfunctioning (75.0%) was the main surgical procedure indication. Lead removal was performed in 44 (52.4%) cases. The rate of postoperative combined events was 32.6%, with 24 (28.6%) cases of UEDVT and six (7.1%) cases of PE. Clinical manifestations of deep venous thrombosis occurred in 10 (11.9%) patients. Independent prognostic factors for UEDVT were severe collateral circulation in the preoperative venography (odds ratio [OR] 4.7; 95% confidence interval [CI] 1.1-19.8; P = .037) and transvenous lead extraction (OR 27.4; 95% CI 5.8-128.8; P < .0001). Conclusion Reoperations involving previously implanted transvenous leads present high rates of thromboembolic complications. Transvenous lead extraction had a significant impact on the development of UEDVT. These results show the need of further studies to evaluate the role of preventive strategies for this subgroup of patients.
bookPart Embolização de tumores e outros procedimentos em radiologia intervencionista(2017) LEAL FILHO, Joaquim Maurício da; JúNIOR, Wilson de Oliveira Sousa- Clinical, Laboratorial, and Urodynamic Findings of Prostatic Artery Embolization for the Treatment of Urinary Retention Related to Benign Prostatic Hyperplasia. A Prospective Single-Center Pilot Study(2013) ANTUNES, Alberto A.; CARNEVALE, Francisco C.; LEAL FILHO, Joaquim M. da Motta; YOSHINAGA, Eduardo M.; CERRI, Luciana M. O.; BARONI, Ronaldo H.; MARCELINO, Antonio S. Z.; CERRI, Giovanni G.; SROUGI, MiguelThis study was designed to describe the clinical, laboratorial, and urodynamic findings of prostatic artery embolization (PAE) in patients with urinary retention due to benign prostatic hyperplasia (BPH). A prospective study of 11 patients with urinary retention due to BPH was conducted. Patients underwent physical examination, prostate specific antigen (PSA) measurement, transrectal ultrasound, and magnetic resonance imaging. International prostate symptom score (IPSS), quality of life (QoL), and urodynamic testing were used to assess the outcome before and after 1 year. Clinical success was 91 % (10/11 patients) with a mean follow-up of 22.3 months (range, 12-41 months). At the first year follow-up, the mean IPSS score was 2.8 points (p = 0.04), mean QoL was 0.4 points (p = 0.001), mean PSA decreased from 10.1 to 4.3 ng/mL (p = 0.003), maximum urinary flow (Qmax) improved from 4.2 to 10.8 mL/sec (p = 0.009), and detrusor pressure (Pdet) decreased from 85.7 to 51.5 cm H2O (p = 0.007). Before PAE, Bladder Outlet Obstruction Index (BOOI) showed values > 40 in 100 % of patients. After PAE, 30 % of patients were > 40 (obstructed), 40 % were between 20 and 40 (undetermined), and 30 % were < 20 (unobstructed). Patients with a BOOI < 20 had higher PSA values at 1-day after PAE. Clinical and urodynamic parameters improved significantly after PAE in patients with acute urinary retention due to BPH. Total PSA at day 1 after PAE was higher in patients with unobstructed values in pressure flow studies.
- Endovascular management of giant common iliac artery pseudoaneurysm after complications in simultaneous pancreas-kidney transplant: a case report(2021) LEITE, Tulio Fabiano de Oliveira; PAZINATO, Lucas Vatanabe; NUNES, Thiago Franchi; LEAL FILHO, Joaquim Mauricio da MottaBackground Pancreatic transplantation is a definitive treatment for selected patients with insulin-dependent diabetes. It is a technically challenging surgery, and vascular complications are the most common cause of pancreatic graft failure. Although rare, pancreas transplants present higher rates of pseudoaneurysms at the vascular anastomosis than other visceral transplants. We present a case of a simultaneous pancreas-kidney transplant complicated with graft failure and common iliac artery pseudoaneurysm that was successfully treated through endovascular techniques. Case presentation A 34-year-old White woman presented with abdominal pain and a history of type 1 diabetes mellitus, end-stage renal disease, and two previous pancreas transplantation failures. The first was a simultaneous pancreas-kidney transplantation performed 7 months prior that was complicated by pancreas graft thrombosis within 1 month and required graft resection. Five months later, she underwent a second pancreas transplantation with another pancreatic graft thrombosis requiring graft resection. Abdominal angiotomography revealed a pseudoaneurysm in the right common iliac artery at the point of the previous graft anastomosis. The patient was successfully treated endovascularly with a covered stent in the common iliac artery. Conclusion Stent graft implantation for the treatment of common iliac artery pseudoaneurysm as a complication of simultaneous pancreas-kidney transplantation is a safe and feasible procedure.
