Are self-expanding stents superior to balloon-expanded in dilating aortas?
Self-expanding stents follow the pulsatile diameter change of the vessel wall, not adversely affecting distensibility after 18 weeks. They show good attachment despite 56% dilation. In contrast, the balloon-expanded stents do not show pulsatile movement and may detach during vessel diameter increase. This may be of importance when choosing stents for endovascular treatment of abdominal aortic aneurysms.
Day case laparoscopic cholecystectomy is safe, feasible, and cost-effective when patients are carefully selected. It provides good patient satisfaction.
