Renal branch occlusion was by far the commonest late failure mode after multibranched endovascular aneurysm repair. The current study provides no basis for a change in patient selection or stent-graft design, only a change in the components used to construct renal branches. It is too early to tell the effect this will have.

patients, multivariate analysis showed HYBRID was associated with significantly higher rates of deep venous thrombosis/stroke (odds ratio, 13.6 vs 0.9; P ¼ .02) and prolonged intubation (odds ratio, 16.0 vs 1.8; P ¼ .003). Conclusions: COPD patients should not be automatically excluded from open TAR because the HYBRID procedure may not represent a safer alternative.

The synergistic integration of high intensity focused ultrasound (HIFU) thermal ablation and HIFU-induced gene therapy represents a promising approach in improving the overall efficacy and quality of cancer therapy. Previous studies have demonstrated that HIFU can induce GFP gene activation under the control of hsp70B promoter in a murine tumor model [1]. Thermal stress has been identified as the primary mechanism to regulate the gene expression. However, the natural heterogeneity and opacity of solid tumors has hindered direct correlation of site-specific gene expression level with in situ thermal dosimetry. We have developed a homogeneous and transparent cell-embedded tissue mimicking phantom as an alternative for simultaneous assessment of temperature distribution, HIFU lesion formation, and gene expression.
