Neointimal hyperplasia associated with the use of u-clip.

The U-Clip (Coalescent Surgical, Sunnydale, CA USA) allows the surgeon to create an interrupted anastomosis in the same amount of time that is required for a continuous anastomosis with the elimination of knotting. Its use is indicated especially in minimally invasive surgery. We describe a case of a patient in which the proximal anastomosis was performed by interrupted suture with Coalescent U-Clip anastomotic device. Six months later, he presented with stenosis of the anastomosis, and intravascular ultrasound showed anastomotic neointimal hyperplasia.
