The purpose of this review is to compare conventional endovascular procedures and the robotic endovascular approach in aortic aneurysm repair. Despite advantages over open surgery, conventional endovascular surgery has limitations. To develop an alternative, efforts have been focused on robotic endovascular systems. ⋯ However, robotic endovascular technology may be limited by the cost of the system, the size of the catheter, and the setup time required preoperatively. Further comparative studies between conventional and robotic approaches regarding cost-effectiveness, safety, and performance in cases involving complex anatomy and fenestrated stent grafts are essential. Nevertheless, this revolutionary technology is increasingly popular and may be the next milestone in endovascular surgery.

Comparative StudyPneumonectomy: risk factor or innocent bystander?
Pneumonectomy is associated with a higher operative mortality rate and worse 5-year survival after resection for non-small-cell lung cancer, compared to lobectomy. We investigated whether pneumonectomy is an independent risk factor for hospital mortality and poor long-term survival, after risk factor adjustment. ⋯ Pneumonectomy is not an independent risk factor for hospital mortality or long-term survival, after adjustment for confounding factors.

Prognostic impact of vascular and lymphovascular invasion in early lung cancer.
The prognostic significance of vascular and lymphatic invasion in non-small-cell lung cancer is under continuous debate. We analyzed the effect of tumor aggressiveness (lymphatic and/or vessel invasion) on survival and relapse in stage I and II non-small-cell lung cancer. ⋯ Vascular and lymphatic invasion can serve as independent prognostic factors in completely resected non-small-cell lung cancer. Intratumoral vascular invasion and lymphovascular space invasion in early stage non-small-cell lung cancer are important factors in overall survival and early tumor recurrence. Further large scale studies with more recent patient cohorts and refined histological techniques are warranted.

Multicenter Study Observational StudyAdvantages of upper brachial artery cannulation in aortic surgery.
The best method of cerebral protection during aortic arch surgery remains controversial. However, antegrade cerebral perfusion seems to be the most favorable because of better neurological outcomes. Although there have been many studies on antegrade cerebral perfusion via upper brachial cannulation, there is a lack of studies focusing particularly on local complications, with objective findings. The aim of this study was to investigate the local neurological and vascular complications following upper brachial cannulation. ⋯ Brachial artery cannulation is technically simple and less time consuming, thus suitable even for emergency cases. With an acceptable risk of local complications, we recommend routine use of upper brachial cannulation for antegrade cerebral perfusion.
