- Endovascular and open repair for blunt aortic injury, treated in one clinical institution in Brazil. A case series(2011) SINCOS, Igor Rafael; AUN, Ricardo; BELCZAK, Sergio Quilici; NASCIMENTO, Luciano Dias; NETTO, Boulanger Mioto; CASELLA, Ivan; SILVA, Erasmo Simao da; PUECH-LEAO, PedroOBJECTIVE: The objective of this retrospective study is to analyze and compare the results of conventional surgical repair and endovascular treatment of blunt aortic injury over the past 8 years. METHODS: Twenty-eight patients (25 male; mean age, 35 years) were treated for blunt aortic injury between April 2001 and March 2009 in a university hospital in Brazil. Twenty-six patients were included in the study: five were treated with operative repair (OR) and 21 with endovascular treatment (TEVAR). Two patients were excluded from analysis: one was managed conservatively, and one was treated with endovascular treatment for chronic dissection related to aortic trauma. RESULTS: Mean age was lower in the OR group than in the endovascular treatment group (17.8 vs. 38 years, P = .003). There was one death in the OR group and four deaths in the endovascular treatment group. Mean follow-up for the overall group was 33.6 months, with 48.7 months (range 8-83 months) for the OR group, and 29.8 months (range 2-91 months) for the TEVAR group. Mean time elapsed from injury to repair was 23.4 hours (range 8-48 h, median 20 h) for the OR group and 30.3 hours (range 2-240 h, median 18 h) for the TEVAR group (P = .374). The duration of surgery was shorter in the endovascular treatment group (142 versus 237 minutes; P = .005). There were no significant differences with respect to the number of postoperative days requiring mechanical ventilation, duration of ICU stay or duration of hospital stay. CONCLUSION: In this retrospective analysis, endovascular treatment was a safe method for repair of blunt aortic trauma, with immediate and midterm results that were comparable to those results obtained with operative repair. No complications from the stent graft were identified during follow-up. Nevertheless, long-term follow-up is necessary to confirm the effectiveness of this treatment.
- Combined Angioplasty Technique of the Carotid Territory and Supra-Aortic Trunk by Double Access (Cervical and Limbs) for Tandem Lesions(2020) RIBEIRO, Felipe S.; CASELLA, Ivan Benaduce; LEIDERMAN, Dafne Braga Diamante; PUECH-LEAO, Pedro; LUCCIA, Nelson DeBackground: The carotid stent angioplasty (CAS) has been the main option for patients with high cardiovascular risk and carotid stenosis. The common femoral artery is still the most used access site; however, the aortic arch manipulation is a critical moment for cerebral embolization. Carotid transcervical access should be considered as a good alternative access route for CAS. Tandem lesions combining supra-aortic trunks and ipsilateral carotid bulb critical stenosis pose a great challenge for the vascular surgeon. Methods: This is a retrospective descriptive study based on medical records of our institution. We report 2 cases of complex cerebral vascular insufficiency and discuss therapeutic options and strategies to protect the cerebrovascular territory avoiding microembolization, as well as demonstrate an alternative and safe total endovascular approach for those cases. Results: We describe the approach of 2 complex cerebral vascular insufficiency cases: case 1, a 63-year-old male with previous ischemic stroke, right internal carotid artery (ICA) occlusion, left ICA stenosis >70%, and critical stenosis of the origin of common carotid artery (CCA); case 2, a 68-year-old female with previous ischemic stroke, left ICA occlusion, brachiocephalic trunk critical stenosis, hypoplastic right vertebral artery, and aortobi-iliac chronic occlusion. In both cases reported here a challenging solution was chosen, little described in the literature, with cerebral filter protection as the first step. In addition, a literature review was performed to discuss the different approach options for tandem injuries of the supra-aortic trunk and carotid bulb. Conclusions: Our initial experience with total endovascular treatment of complex tandem lesions of the carotid territory and supra-aortic trunks show that transcervical access, coupled with distal protection filter device on the first step, is a safe and effective technique for preventing neurological events.
- Generic versus branded enoxaparin in prophylaxis and treatment of vein thrombosis(2015) CASELLA, Ivan Benaduce; PUECH-LEAO, PedroObjectives: to compare the biological efficacy of generic enoxaparin (Heptron (TM)) versus branded Sanofi-Aventis enoxaparin for prophylaxis and treatment of lower-extremity deep venous thrombosis (DVT) in a prospective, randomized, openlabel study. Methods: patients with diagnosed lower-extremity DVT (therapeutic branch, n=57) and patients requiring venous thromboembolism (VTE) prophylaxis after arterial vascular surgery or major lower-extremity amputations (prophylactic branch, n=57) were randomized to receive generic or branded enoxaparin for up to seven days. Enoxaparin activity was measured by estimating blood anti-factor Xa levels at the peak plasma concentration. As secondary outcomes, development or progression of VTE events, major adverse events and major bleeding events were considered for efficacy and safety comparisons. Results: DVT therapy: twenty-five patients received generic enoxaparin while 32 received branded enoxaparin (subcutaneous, 1 mg/kg BID). Mean percentages of anti-factor Xa levels within the target ranges were 62 +/- 35.4% and 67.5 +/- 24.7%, respectively (p=.035 for non-inferiority). No patient presented DVT progression, clinically detectable pulmonary embolism, or major bleeding events in any subgroup. DVT prophylaxis: Thirty patients received generic enoxaparin and 27 received branded enoxaparin (subcutaneous, 40 mg/day). Mean percentages of anti- factor Xa levels within the target ranges were 77.9 +/- 30.9% and 77.8 +/- 32.9%, respectively (p = .009 for non-inferiority). There were no cases of VTE or major bleeding events in any subgroup. Conclusion: generic and branded enoxaparins exhibited similar in vivo responses as measured by the anti-factor Xa activity, as well as similar clinical efficacy and safety outcomes.

- Carotid Plaque Morphology in Asymptomatic Patients with and without Metabolic Syndrome(2017) CURY, Marcus Vinicius Martins; PRESTI, Calogero; BONADIMAN, Suellen Stevam Timotheo; CASELLA, Ivan Benaduce; BENABOU, Joseph Elias; SILVA, Erasmo Simao da; LUCCIA, Nelson de; PUECH-LEAO, PedroBackground: The aim of this study was to determine the impact of metabolic syndrome (MetS) on the morphology of carotid plaques, as evaluated using duplex ultrasound (DUS) with computer-assisted analysis. Methods: In this cross-sectional observational study, we analyzed 148 carotid artery plaques in asymptomatic patients. Data were obtained via clinical and laboratory examinations, and DUS was performed by a single operator. All plaques were scanned in a longitudinal fashion, and the best segment was selected, recorded, and evaluated using dedicated software. The main software-based analyses included gray-scale median (GSM) measurements and carotid plaque morphology histograms. Results: MetS was identified in 51.8% of patients. Comparisons of patients with MetS and patients without MetS indicated that the former patients used more classes of antihypertensive drugs (2.49 vs. 1.93; P = 0.004) and were treated with statins for a longer period (71.08 vs. 49.17 months; P = 0.003). Most patients of both types exhibited moderate carotid artery stenosis ranging from 50% to 69% (n = 62; 37.3%), and MetS was not associated with an increased prevalence of severe carotid artery stenosis. The mean GSM was greater in the MetS group than in the non-MetS group (74.18 vs. 61.63; P = 0.012). The histogram analysis revealed that there were lower quantities of blood and fat (2.91 vs. 3.88; P = 0.006; 10.21 vs. 15.08; P = 0.004, respectively) and more fibrous tissue (19.93 vs. 14.55; P = 0.015) in the carotid plaques of patients with MetS than in the carotid plaques of patients without MetS. Conclusions: The present study demonstrated that MetS did not affect the stenosis grade or did it lead to unstable carotid plaques.
- Endovascular Therapy Provides Similar Results of Bypass Graft Surgery in the Treatment of Infrainguinal Multilevel Arterial Disease in Patients with Chronic Limb-Threatening Ischemia in All GLASS Stages(2020) CASELLA, Ivan Benaduce; SARTORI, Camila Holanda; FAUSTINO, Carolina Brito; MARIZ, Maria Paula Vieira; PRESTI, Calogero; PUECH-LEAO, Pedro; LUCCIA, Nelson DeBackground: Extensive infrainguinal arterial disease still pose a challenge for technical and clinical success of percutaneous angioplasty. The purpose of this study was to compare the results of concomitant femoropopliteal and infrapopliteal percutaneous angioplasty/stenting (PTA/S) with distal bypass graft surgery (BGS) in patients with chronic limb-threatening ischemia (CLTI). Method: In a single-center retrospective investigation between 2011 and 2017, 668 revascularization procedures for CLTI were reviewed. Concomitant femoropopliteal and infrapopliteal disease was identified in 153 CLTI patients, treated with BGS (48) using autogenous veins as substitute or PTA/S in a single procedure (105). A subgroup of patients with complex, extensive arterial lesions (GLASS stage III) received additional analysis. Primary outcomes were limb salvage and survival. Results: The mean follow-up time was 21.4 months. Patients treated with PTA/S were significantly older and with predominance of females, diabetes and chronic kidney disease. Smoking was more common in patients treated with BGS. The BGS group showed a 36-month survival rate of 73.4%, whereas the PTA/S group presented a survival of 61.3% in the same interval (P = 0.25). The 36-month cumulative limb salvage rate was 53.3 and 59.7% for BGS and PTA/S, respectively (P = 0.24). For GLASS stage III patients, 36-month limb salvage rates were 54.4% for the PTA/S group and 50.2% for the BGS group (P = 0.29). Multivariate analysis pointed poor runoff status (all endovascular patients) and diabetes (GLASS III endovascular patients) as risk factors for limb loss. Conclusion: PTA/S and BGS presented similar results of limb salvage and survival in the treatment of concomitant femoropopliteal and infrapopliteal arterial disease in patients with CLTI, even for patients with extensive and complex arterial disease.
- Medical Therapy for Asymptomatic Patients and Stent Placement for Symptomatic Patients Presenting with Carotid Artery Near-Occlusion with Full Collapse(2018) NEVES, Celso Ricardo Bregalda; CASELLA, Ivan Benaduce; SILVA, Erasmo Simao da; PUECH-LEAO, PedroPurpose: To report long-term results of stent placement and medical therapy for symptomatic and asymptomatic patients, respectively, with carotid artery near-occlusion with full collapse. Materials and Methods: Between January 2008 and December 2010, 204 carotid arteries diagnosed by duplex scanning as exhibiting complete occlusion were re-examined with CT angiography; 46 arteries in 46 patients were patent with threadlike lumens and were reclassified as exhibiting near-occlusion with full collapse. Asymptomatic patients (n = 22) received best medical therapy (BMT) alone, and symptomatic patients (n = 24) were referred for carotid artery stent (CAS) placement plus BMT. Patients underwent clinical follow-up for 63.9 months +/- 23.6 and duplex surveillance. Results: None of the 22 asymptomatic patients treated with BMT alone experienced neurologic events during the follow-up interval. Four died of unrelated causes, resulting in a cumulative survival rate of 81.8%. Technical failure occurred in 5 of 24 symptomatic patients, but none had perioperative complications related to inability to cross the near-occlusion. Of the 19 patients with procedural success, 1 developed immediate upper limb monoparesis; none had periprocedural myocardial infarction, and none died. At 60-month follow-up, patients who underwent successful CAS placement had neurologic event-free and cumulative survival rates of 89.4% and 89.4%; patients with failed recanalization had neurologic event-free and cumulative survival rates of 0% and 40.0% (P = .01). Conclusions: Asymptomatic patients with carotid near-occlusion with full collapse experienced good outcomes with BMT alone. Symptomatic patients who underwent CAS placement demonstrated long-term survival and freedom from neurologic event rates comparable to those of asymptomatic patients.
- Obesity Is a Risk Factor for Significant Carotid Atherosclerosis in Patients Aged 39 to 55 Years(2014) SILVA, Erasmo Simao da; GIGLIO, Pedro Nogueira; WAISBERG, Daniel Reis; JAQUETA FILHO, Richard Geraldo; CASELLA, Ivan Benaduce; PUECH-LEAO, PedroWe compared the prevalence of risk factors between young and old individuals with significant carotid atherosclerosis. We retrospectively reviewed the records of patients aged 39 to 55 years (group I) and aged >= 60 years (group II) with significant atherosclerotic stenosis at the carotid bifurcation. Group I patients had significantly higher values for the following factors: weight, height, body mass index, diastolic pressure, prevalence of current smoking, total and low-density lipoprotein cholesterol and significant lower values for systolic pressure, creatinine, and prevalence of coronary artery disease. Group I patients were more symptomatic and showed higher rates of carotid occlusion and near occlusion. Atherosclerosis of the carotid bifurcation was more aggressive in the younger group, with a higher rate of occlusion and near occlusion. Obesity and smoking were significant risk factors for young patients in this sample.
- The similarities and differences among patients with abdominal aortic aneurysms referred to a tertiary hospital and found at necropsy(2015) SILVA, Erasmo S. da; GORNATI, Vitor C.; CASELLA, Ivan B.; AUN, Ricardo; ESTENSSORO, Andre E. V.; PUECH-LEAO, Pedro; LUCCIA, Nelson DeObjective: To analyze the characteristics of patients with abdominal aortic aneurysms referred to a tertiary center and to compare with individuals with abdominal aortic aneurysm found at necropsy. Methods: We have retrospectively analyzed the medical records of 556 patients with abdominal aortic aneurysm and 102 cases abdominal aortic aneurysm found at necropsy. Results: At univariated analysis, hypertension, tobacco use and maximum diameter were significant risk factors for symptomatic aneurysm, while diabetes tended to be a protective factor for rupture. By logistic regression analysis, the largest transverse diameter was the only one significantly associated with abdominal aortic aneurysm rupture (p<.0001, odds ratio 1.7, 95% confidence interval 1.481-1.951). Intact abdominal aortic aneurysm found at necropsy showed similarities with outpatients in relation to abdominal aortic aneurysm diameter and risk factors. Conclusion: Intact abdominal aortic aneurysm at necropsy and at outpatients setting showed similarities that confirmed that abdominal aortic aneurysm repair is less offered to women, and they died more frequently with intact abdominal aortic aneurysm from other causes.
