Layered wrapping technique combined with oxidized cellulose and vascular prosthesis for effective haemostasis in aortic surgery.

Bleeding from anastomotic sites is one of the major complications of aortic surgery. We describe a novel double-layer wrapping technique using a combination of oxidized cellulose and a vascular prosthesis to effectively achieve haemostasis. The anastomotic site is surrounded by a prosthetic graft inlaid with a strip of Nu-Knit. These are fixed by horizontal mattress and over-and-over sutures. Nu-Knit acts as an ideal cushion to achieve haemostasis, because it has a haemostatic effect and fills the space between the anastomotic site and wrapping graft. This technique is simple, and facilitates adequate haemostasis without complications.
