Objectives To determine the clinical profile of patients with femoropopliteal injuries, the trauma mechanisms, and treatment and identify which factors led to unfavorable outcomes. Methods A retrospective study based on the medical records of patients treated from 2017 to 2021. The following data were assessed: sex, age, distance to reach the hospital, trauma mechanism, hypovolemic shock, additional injuries, treatment of vascular injuries, whether fasciotomy was needed, inappropriate intraoperative decisions, and injury severity score. Need for surgical reintervention, amputation, and death were defined as unfavorable outcomes. Univariate, bivariate, and logistic regression analyses were conducted. Results The sample comprised 94 patients; 83% were men; mean age was 30.8 years; combined arterial and venous injuries prevailed (57.5%); and superficial femoral vessels were the most affected (61.7%). Penetrating mechanisms prevailed (80.9%). Arterial injuries were most frequently treated with venous graft (59.6%) and venous injuries underwent ligation (81.4%). In 15% of cases, inappropriate surgical decisions were detected; most often use of the ipsilateral great saphenous vein for arterial reconstruction. Unfavorable outcomes occurred in 44.7%: surgical reintervention was necessary in 21.3% and limb amputation in 25.5%, while 9.5% of the patients died. Conclusions These injuries mainly involved young men, victims of gunshot wounds. Superficial femoral vessels were the most injured; concomitant non-vascular trauma was frequent, mainly fractures. Inappropriate surgical decisions increased the need for reinterventions by 34 times. Need for fasciotomy, presence of fracture/dislocation, blunt trauma mechanism, and popliteal artery injury increased the risk of amputation.","PeriodicalId":14814,"journal":{"name":"Jornal Vascular Brasileiro","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135658967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives To assess the prevalence of rare visceral aneurysms on CAT scans performed for diagnosis and follow-up of patients with other vascular pathologies. Methods This cross-sectional study began by accessing all reports from CAT scans performed between January 2005 and July 2021 at a private hospital of excellence located in the city of São Paulo. A software program for pre-indexed reports was used to search the Radiological Information System (RIS) database to identify reports of patients with intra-abdominal aneurysms. Results CAT scan reports from 92,883 patients were accessed. Of these, 2,597 (2.795%) showed intra-abdominal aneurysms, 937 (1.063%) of which were visceral, including 158 (0.171%) rare visceral aneurysms, which were more frequent among male patients and in the following segments: celiac trunk (0.098%), superior mesenteric (0.033%), left gastric (0.010%), pancreatic-duodenal (0.009%), and gastroduodenal arteries (0.005%) and the pancreatic arch (0.004%).

Financial support: None. Conflicts of interest: No conflicts of interest declared concerning the publication of this article. Dear Editor, With interest we read the article by Sobreira et al. about the thromboembolic complications of COVID-19 vaccines.1 This study has important implications, but no mention is made regarding these complications in COVID-19 patients. It is therefore necessary to discuss this topic and possible pathogenic mechanisms. Coagulopathy is a common feature of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its incidence increases in severe cases.2 The mechanisms of thrombotic events are multifactorial and platelets play a major role in this phenomenon. Beyond hemostasis and thrombosis, platelets are also capable of sensing and responding to invading pathogen and immune signals.3 Virusplatelet interactions may serve as part of the immune response or of viral counterdefense strategies. Platelets can interact with and respond to viruses via different mechanisms including phagocytosis and production of antiviral molecules. Conversely, they can also shelter several viruses and increase their transport ability throughout the circulation. Virus-mediated activation of platelets may also activate release of various pro-inflammatory mediators which lead to development of virus-induced immunopathology.4 Both positive and negative effects depend on the interaction between viral proteins and host cell receptors. Interactions can occur directly via various immune receptors in platelets or indirectly through plasma proteins. Platelets also express angiotensinconverting enzyme 2 (ACE2) which serves as the primary receptor for SARS-CoV-2 and facilitates virus entry into host cells.5 COVID-19 thrombotic complications may be the result of direct or indirect impacts of viral infection. SARS-CoV-2 can directly activate ACE2 and potentiates platelet activation. Moreover, the SARS-CoV-2 spike protein enhances the potential of thrombosis and recombinant human ACE-2 protein can suppress virus-induced platelet activation. The virus can also directly induce platelet releasing coagulation factors and inflammatory cytokines and increases formation of leukocyte-platelet aggregates. Platelets may also be activated indirectly, through sensing of an inflammatory microenvironment and subsequent dysfunction of vascular endothelium, which are induced by viral infection. The inflammatory milieu may cause uncontrolled platelet activation which consecutively may lead to pathophysiological effector activities. Moreover, immune complex containing viral particles may impact on the platelet hyperactivity in COVID19 patients.6 Altogether, platelets may be affected by SARSCoV-2. Therefore, understanding of the underlying mechanisms can be beneficial in promoting assessment and treatment of COVID-19 patients.","PeriodicalId":14814,"journal":{"name":"Jornal Vascular Brasileiro","volume":"22 ","pages":"e20220101"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10010266/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9123748","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}
