Evaluation of the Effectiveness of Endovascular Treatment of Type 2 Endoleaks.

Background: Endovascular abdominal aortic aneurysm repair (EVAR) is a safe and minimally invasive alternative to open surgical repair for infra renal aortic aneuvrysm. EVAR requires lifelong post-procedural surveillance. Endoleaks represent the main complication.

Generation of squeezed light vacuum enabled by coherent population trapping.

We demonstrate the possibility to generate squeezed vacuum states of light by four wave mixing (FWM) enabled coherent population trapping in a metastable helium cell at room temperature. Contrary to usual FWM far detuned schemes, we work at resonance with an atomic transition. We investigate the properties of such states and show that the noise variances of the squeezed and anti-squeezed quadratures cannot be explained by the simple presence of losses.

Combined Pull through and Balloon Anchoring Bailout Technique to Repair a Failed Bifurcated Endovascular Aortic Repair.

Background: To describe a bailout technique used to manage the left stump of a bifurcated endograft that was stuck above a narrowed distal aortic neck.

Methods: An 80-year-old man with a suprarenal aneurysm was treated with a custom-made 4-vessel fenestration endograft. During the procedure, the left stump of the distal bifurcated graft module was chased out of a narrow distal aortic neck and became stuck horizontally at the bottom of the aortic aneurysmal sac.

Propensity Score Analysis Comparing Videothoracoscopic Lobectomy With Thoracotomy: A French Nationwide Study.

Background: Video-assisted thoracoscopic surgery (VATS) lobectomy has recently become the recommended approach for stage I non-small cell lung cancer. However, these guidelines are not based on any large randomized control trial. Our study used propensity scores and a sensitivity analysis to compare VATS lobectomy with open thoracotomy.

Surgical management of spontaneous pneumothorax: are there any prognostic factors influencing postoperative complications?

Objectives: There are no guidelines regarding the surgical approach for spontaneous pneumothorax. It has been reported, however, that the risk of recurrence following video-assisted thoracic surgery is higher than that following open thoracotomy (OT). The objective of this study was to determine whether this higher risk of recurrence following video-assisted thoracic surgery could be attributable to differences in intraoperative parenchymal resection and the pleurodesis technique.
