ITalian Excluder Registry and results of Gore Excluder endograft for the treatment of elective infrarenal abdominal aortic aneurysms

BackgroundTo report the midterm results of elective endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAAs) in a multicenter, clinical unsponsored registry using the Gore Excluder endograft.MethodsThis study is a retrospective analysis of a multicenter, prospective registry that involved nine centers in Italy. Periodic clinical and radiographic follow-up with computed tomography scans were performed at 1, 6, and 12 months after the procedure, and on a yearly basis thereafter.ResultsA total of 872 patients underwent elective EVAR. Primary technical success was 97.5%, and hospital mortality was 1.0% (9/872). At least 816 (93.6%) patients underwent a follow-up control. Freedom from all-cause death was estimated to be 97.9% at 1 year, 93.4% at 3 years, and 88.5% at 5 years. Aneurysm-related mortality was 1.6% (n = 13) with only two late AAA-related deaths observed at 21 and 36 months. Significant predictors of all-cause mortality included age (P < .001) and AAA maximum diameter (P = .027). Overall conversion rate was 2.3% (n = 19). Mean elapsed time from initial intervention to surgical conversion was 23 ± 18 months (range, 0-52 months). Late rupture was detected in four (0.5%) cases: two of these patients died after conversion. The rate of any reintervention was 9.4% (n = 77); most of them were required within the first 24 months. The leading cause of reintervention was endoleak (n = 41; 5.0%). Limb thrombosis occurred in nine (1.1%) cases. Freedom from reintervention at 1, 3, and 5 years of follow-up were 98.6%, 94.6%, and 86.5%.ConclusionsThe ITalian Gore Excluder Registry is the largest clinical unsponsored registry using a single device, with the longest follow-up period so far. The present experience confirms the effectiveness of EVAR using the Gore Excluder with low rates of mortality, migration, reintervention, and limb thrombosis

The jaundiced newborn: which early monitoring for a safe discharge?

Neonatal jaundice is one of the most common causes of prolonged hospital stay or readmission of a near-term or term baby. Reason of concern at early discharge of a jaundiced newborn is that of bilirubin neurotoxicity, even if a serum bilirubin concentration surely toxic for the brain is still unknown. Kernicterus and severe neonatal hyperbilirubinemia are still problems in the third millennium and the American Academy of Pediatrics claimed the pediatric community to increase vigilance in order to reduce the occurrence of these dramatic events. The only existing kernicterus registry is the pilot USA kernicterus registry whose data on 125 kernicteric term and near term babies from 1992 to 2004 have been recently published. Nobody of the kenicteric babies into the USA register had a serum bilirubin levels below 20 mg/dL. All the babies who suffered from kernicteric sequelae were discharged as healthy from hospital and then, 86% of them, readmitted in the first ten days of life. In the majority of babies (69%) a cause of the severe hyperbilirubinemia was not found. Current knowledge on mechanism of neurological damage induced by bilirubin, unfortunately, does not allow to have a universal evidenced based guideline on how to manage neonatal jaundice. Thus, the existing national guidelines contain inevitable differences in the recommended procedure. Waiting for the future italian guidelines the paper illustrates a proposal of management of neonatal jaundice in term or near term newborns based on available scientific evidence and national guidelines published in english language

Textural and minerochemical features of NWA 1807 and 2180, two new CV3 chondrites from northwest Africa

A textural and minerochemical study has been performed on NWA 1807 and 2180 chondrites in order to determine sizes and typologies of chondrules, relative abundances of mineral phases, compositions of main phases and bulk oxygen isotope composition

A 20-year experience with surgical management of true and false internal carotid artery aneurysms

Aim of the study: The aim of this study was to retrospectively analyse early and late results of surgical management of internal carotid artery (ICA) true and false aneurysms in a single-centre experience. Materials and methods: From January 1988 to December 2011, 50 consecutive interventions for ICA aneurismal disease were performed; interventions were performed for true ICA aneurysm in 19 cases (group 1) and for ICA post-carotid endarterectomy (CEA) pseudo-aneurysm in the remaining 31 (group 2). Early results (&lt;30 days) were evaluated in terms of mortality, stroke and cranial nerves' injury and compared between the two groups with χ2 test. Follow-up results (stroke free-survival, freedom from ICA thrombosis and reintervention) were analysed with Kaplan-Meier curves and compared with log-rank test. Results: All the patients in group 1 had open repair of their ICA aneurysm; in group 2 open repair was performed in 30 cases, while three patients with post-CEA aneurysm without signs of infection had a covered stent placed. There were no perioperative deaths. Two major strokes occurred in group 1 and one major stroke occurred in group 2 (p = 0.1). The rates of postoperative cranial nerve injuries were 10.5% in group 1 and 13% in group 2 (p = 0.8). Median duration of follow-up was 60 months (range 1-276). Estimated 10-year stroke-free survival rates were 64% in group 1 and 37% in group 2 (p = 0.4, log rank 0.5); thrombosis-free survival at 10 years was 66% in group 1 and 34% in group 2 (p = 0.2, log rank 1.2), while the corresponding figures in terms of reintervention-free survival were 68% and 33%, respectively (p = 0.2, log rank 1.8). Conclusions: Surgical treatment of ICA aneurismal disease provided in our experience satisfactory early and long-term results, without significant differences between true and false aneurysms. In carefully selected patients with non-infected false aneurysm, the endovascular option seems to be feasible.© 2012 European Society for Vascular Surgery
