Abstract:
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.
