Direct and indirect costs were calculated as sums of the respective cost components of the procedure based on values from the federal government's price panel. To illustrate the potential cost-effectiveness of RFA, these costs were compared to those of 9 saphenectomy procedures performed on the same day as the RFA procedures. All analyses were descriptive, with no formal statistical testing.Results: The mean operating room hourly rate for RFA was 127.50 BRL. The costs of anesthetics/medications, materials, and single-use catheter per patient were 32.63 BRL, 81.49 BRL, and 1600.00 BRL, respectively. Patients were absent from work for < 15 days (mean, 11.44 days), not incurring sick leave payments from the Social Security Administration. The total mean cost for RFA was lower than that of same-day saphenectomy (1841.62 BRL vs 2045.40 BRL).Conclusions: This pilot study provided essential insights into resource utilization at a Brazilian teaching hospital, with the goal of improving treatment efficiency and ensuring the best cost-benefit ratio for patients.","PeriodicalId":14814,"journal":{"name":"Jornal Vascular Brasileiro","volume":"24 ","pages":"e20240172"},"PeriodicalIF":0.8,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12258812/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144637054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Brazil, it affects 45% of women and 30% of men. Currently, endovenous thermal ablation (EVTA) of the saphenous vein is the method of choice in the treatment of varicose veins. As a minimally invasive procedure that promotes quick recovery and does not require hospitalization, it can be performed on an outpatient basis.Objectives: To evaluate the safety and cost-benefit of outpatient varicose vein treatment in a clinic compared to the same procedure performed in a hospital environment.Methods: A uncontrolled retrospective transversal study of case series evaluated a random group of 50 patients undergoing EVTA for the treatment of varicose disease by the same group of vascular surgeons. Twenty-five underwent the procedure in a tertiary hospital environment and 25 on an outpatient basis. The average costs of room fees and materials from both groups were analyzed and statistically compared with the Student's t-test. Intraoperative and postoperative complications were assessed.Results: The average hospital cost of the procedure was R$ 1391.99 (± 280.8) in the hospital and R$ 1593.40 (± 99.53) in the clinic. The Student's t-test showed a significant difference with p=0.02. No patient had complications either intraoperatively or postoperatively.Conclusions: Outpatient surgery, despite having a statistically higher cost than hospital surgery in Brazil, is safe and has a positive cost-benefit for the patient.","PeriodicalId":14814,"journal":{"name":"Jornal Vascular Brasileiro","volume":"24 ","pages":"e20240160"},"PeriodicalIF":0.8,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12212346/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144540265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the pathophysiology and surgical approaches to this disease is essential for best therapeutic performance.Objectives: We aimed to improve previously described methods for creating thoracoabdominal aortic aneurysms in a porcine animal model, reducing surgical procedure time and specimen mortality.Methods: A total of 18 swine underwent a surgical procedure to create a TAA. An autologous peritoneal patch was used to create the aneurysm in 2 animals, and a bovine pericardial patch was used in the other 16. The animals were followed up postoperatively, and the aneurysm sac was reexamined after 4 weeks. The animals that did not die in the post-operative period were euthanized according to institutional recommendations.Results: All of the animals underwent laparotomy with retroperitoneal access. Two received an autologous peritoneal patch and 16 received a bovine pericardial patch. Three animals underwent single suprarenal clamping, while 15 underwent sequential clamping. There were no differences in operative time (p=0.207) or total clamping time (p=0.276) between groups. There was a higher mortality rate after 4 weeks in animals that received single clamping (100%) than sequential clamping (26.7%) (p=0.0017).Conclusions: The experimental model of TAA using a bovine pericardial patch and a sequential clamping technique provided a stable and reliable platform that remains stable and patent for up to 4 weeks. This model can be extremely valuable for assessing new endovascular therapy options in living organisms.","PeriodicalId":14814,"journal":{"name":"Jornal Vascular Brasileiro","volume":"24 ","pages":"e20240182"},"PeriodicalIF":0.8,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12186686/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144484443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Complications occurred in 18.99% of the patients, and unfavorable surgical outcomes occurred in 3.15%, of which cardiac and pulmonary comorbidities were the most frequent. Aneurysms with smaller diameters presented fewer complications and unfavorable surgical outcomes than those with larger diameters. The ideal threshold for repair remains uncertain. Although diameter is an important indicator, other factors should be considered. These aneurysms should be treated electively at earlier stages due to their uncertain rupture risk and the higher prevalence of complications at larger diameters.

Variations in arterial anatomy were classified according to the Michels system (1966), while those in regarding portal vein anatomy were classified according to the Cheng system (1996).Results: A total of 31.2% of the cases showed variations in arterial vascularization, the most prevalent being type V (8.2%). No participants were identified with type X, and 0.4% could not be classified. A total of 21.8% showed variation in venous vascularization, with type IV being the most prevalent (8%).Conclusions: Medical knowledge of these variations and their prevalence is fundamental for the correct surgical management of upper abdomen pathologies and lower rates of postoperative complications. Variations not classified by previous trials should be categorized according to their clinical importance, and new studies should clarify national population patterns to reduce mortality rates from surgical procedures that involve these vessels.","PeriodicalId":14814,"journal":{"name":"Jornal Vascular Brasileiro","volume":"24 ","pages":"e20240110"},"PeriodicalIF":0.8,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12143226/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144247938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
