RESUMO
PURPOSE: To report a single-center result of patients with pararenal aneurysms treated with inner-branched endograft. MATERIALS AND METHODS: This retrospective study analyzed prospectively collected data of patients treated with elective inner-branched endovascular aneurysm repair (iBEVAR) using an Artivion® E-xtra custom-made endograft. Primary endpoints were clinical and technical success after iBEVAR. Secondary endpoints were overall survival, target vessel patency during follow-up, aneurysm-related mortality, and freedom from reintervention. RESULTS: Over a 56-month period, a total of 23 patients (19 men; 72.3±7.2 years) were treated with iBEVAR with a mean follow-up of 15 months. Technical success was achieved in 96% of procedures, incorporating 87 inner branches. Two (8.3%) intraoperative complications (target vessel dissection) were reported, without additional reinterventions needed. Two (8.3%) patients died within 30 days after initial procedure. One due to respiratory failure and the other from an ischemic stroke. During follow-up, 3 patients (13%) required reintervention, either to repair a type I or type III endoleak (n=2) or to place an iliac-branched device, that did not succeed during the initial iBEVAR procedure (n=1). Primary target vessel patency and freedom from reintervention during follow-up was, respectively, 98.9% and 87%. We revealed no aneurysm-related mortality. Overall survival was 78.3%. CONCLUSION: The present study confirms previous findings that iBEVAR on the Artivion® E-xtra design platform is an effective and safe procedure achieving high technical success rate in the treatment of pararenal abdominal aortic aneurysms. CLINICAL IMPACT: Inner branched stent-graft configuration combines the benefits of FEVAR and outer-branched stent-graft technology. Implementation of inner branches in stent-grafts is gradually becoming more widespread for the treatment of aneurysms. This report supports the safe and high technical success rate of inner branched stent-grafts in treatment of pararenal abdominal aortic aneurysms.
RESUMO
AIM: The objective of this study was to analyze the incidence and treatment options of occult cancer or atypical lesions found in the histopathological examination of reduction mammoplasty (RM) specimens. The role of preoperative mammography and systematic histopathological examination are discussed. METHODS: We performed a retrospective single-center database review of all patients who underwent a RM between January 2005 and December 2014. Preoperative examination, histopathological findings and follow-up were documented. RESULTS: A total of 1045 patients underwent RM, of which 97% were bilateral (1021). All patients received a mammography and routine clinical examination to exclude cancer preoperatively. The overall mean patient age was 40.2 years (14.2-73.4). A total of 19 patients (1.18%) had significant histopathological findings, all of whom were over 40 years of age. There were 4 incidental carcinomas (0.38%), of which 2 were DCIS (0.19%) and 2 invasive ductal carcinomas (0.19%). CONCLUSIONS: Incidence of postoperative diagnosis of occult breast cancer in RM specimens remains low, but poses significant therapeutic challenges. While emphasis should lay on preoperative diagnostics, routine histological analysis of RM specimens is recommended.
