OBJECTIVE The aim of the present comprehensive review was to present an overview of the clinical presentation and treatment options for external (EJVAs) and internal jugular vein aneurysms (IJVAs) to help clinicians in evidence-based decision making. METHODS A systematic literature search was conducted in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement and included MEDLINE, Embase, Cochrane Library, Scopus, WHO (World Health Organization) trial register, ClinicalTrials.gov, and the LIVIVO search portal. The inclusion criteria were studies of patients who had presented with IJVAs or EJVAs. The exclusion criteria were animal and cadaver studies and reports on interventions using the healthy jugular vein for access only (ie, catheterization). Analysis of the pooled data from all eligible case reports was performed. RESULTS From 1840 identified reports, 196 studies were eligible. A total of 256 patients with JVAs were reported, with 183 IJVAs and 73 EJVAs. IJVAs were reported to occur in 66% on the right side compared with the left side (P��= .011). The patients with IJVAs were mostly children (median age, 12��years; interquartile range, 5.8-45.2��years). The patients with EJVAs were young adults (median age, 30��years; interquartile range, 11.0-46.5��years). EJVAs were more frequently reported in women and IJVAs in men (P��= .008). Most of the patients were asymptomatic. Pulmonary embolization in association with thrombosed EJVAs was only reported for one patient. A report of the outcomes after surgery and conservative management was missing for ���50% of the patients. No relevant complications were reported after ligation of the EJVA without reconstruction. Intracranial hypertension after ligation of the right-sided IJVA was reported in three children; in one of them, a pontine infarction was observed. CONCLUSIONS JVAs are a disease of the younger population but can occur at any age. It seems to be safe to observe patients with nonthrombosed JVAs. However, in the presence of thrombus or pulmonary embolization, surgical treatment should be considered. A reconstruction technique of the IJVA with venous patency preservation should be preferred.

BACKGROUND Surgical aortic valve replacement (SAVR) is the treatment of choice in severe symptomatic aortic valve disease. New techniques and prostheses have been recently developed to facilitate the procedure and reduce aortic cross-clamp time (AOx). The aim of this study was to analyse the different procedural steps in order to identify the most time-consuming part during aortic clamping time and to compare impact of experience on procedural aspects. METHODS AOx during SAVR was divided into five consecutive steps. Duration of each step was measured. The first procedural step started with clamping of the aorta and ended with the beginning of the second step starting with the resection of the native aortic valve. The third step started with placement of the first valve anchoring suture, the fourth step started with tying of the first suture and the fifth and final step started after the cut of the last suture and ended with removal of the aortic clamp. Surgeons were divided into two groups based on their experience, which in our analysis was defined as a total SAVR experience of more than 100 procedures. RESULTS From March 2013 to August 2015 57 nonconsecutive patients (33% female; age, median 71.0 years, interquartile range 65.0-76.0) undergoing isolated SAVR for severe aortic valve stenosis in our institution were included in this process analysis. Two different prostheses were implanted. Forty-eight (84%) patients received a tissue valve (Perimount Magna Ease, Edwards Lifesciences, Irvine, USA) and 9 (16%) patients received a mechanical prosthesis (Medtronic AP 360, St-Paul, MN, USA). The mean estimated risk of mortality was 1.1% (0.7-1.6) according to the logistic EUROScore II. Overall duration of AOx was 50.5 ± 13.8 min, with 32.3% (16.4 ± 5.9 min) accounting for placing the sutures into the native annulus and the prosthetic sewing ring and 18.5% (9.2 ± 3.0min) accounting for tying and cutting the sutures. Surgeons with more experience performed 35 operations (61.4%) and needed an average of 44.1 ± 11.5 min versus 60.6 ± 11.0 min (p
