Meta Analysis Comparative Study
Safety of endovascular treatment of carotid artery stenosis compared with surgical treatment: a meta-analysis.
Since publication of previous meta-analyses comparing endovascular and surgical treatment of patients with carotid artery stenosis, two further large-scale trials have been conducted, almost doubling the number of patients available for analysis. Therefore, it is justified to update these meta-analyses. ⋯ The expressiveness of this meta-analysis is limited by the heterogeneity of some tests. The main result is that surgical treatment still remains the gold standard for treatment of patients with symptomatic carotid artery stenosis, who do not have an increased surgical risk. Carotid artery stenting is neither safer than nor as safe as carotid endarterectomy in large clinical trials when short-term stroke and death rates are taken into account. Further recruitment into ongoing randomized trials is strongly recommended.

Comparative Study Controlled Clinical Trial
Equivalent secondary patency rates of upper extremity Vectra Vascular Access Grafts and transposed brachial-basilic fistulas with aggressive access surveillance and endovascular treatment.
The 2006 update of the DOQI guidelines has stated that in patients with end-stage renal disease, autogenous radial-cephalic, or brachial-cephalic fistulas are the preferred access modalities, followed by transposed brachial-basilic (TBB) fistulas and prosthetic arteriovenous (AV) grafts. AV grafts are in general least preferred; however, there is very limited data comparing directly the last two modalities. The aim of the present study is to compare outcomes of the TBB fistula and the Vectra Vascular Access Graft. ⋯ Aggressive graft surveillance and endovascular treatment methods can yield equivalent long-term secondary patency rates between Vectra graft and TBB fistulas. The advantage of earlier use of Vectra graft must be balanced against the need for more frequent secondary interventions and the risk of graft infection.

Endovascular repair (EVR) is emerging as first-line treatment for patients with superior vena cava (SVC) syndrome of benign etiology, but data on its durability remain scarce. The aims of this study were to assess the efficacy and durability of EVR and compare results of EVR with open surgical reconstruction (OSR). ⋯ OSR of benign SVC syndrome is effective, with durable long-term relief from symptoms. EVR is less invasive but equally effective in the mid-term, albeit at the cost of multiple secondary interventions, and is an appropriate primary treatment for benign SVC syndrome. OSR remains an excellent choice for patients who are not suitable for EVR or in whom the EVR fails.

Prospective validation of prognostic scoring systems for ruptured abdominal aortic aneurysm (AAA) is lacking. This study assesses the validity of three established risk scores and a new prognostic index. ⋯ Prospective validation shows that the Hardman Index, GAS, and V-POSSUM and RAAA-POSSUM scores do not perform well as predictors for death after ruptured AAA. The ERAS accurately stratifies perioperative risk but requires further validation.
