The anatomy of the mesenteric arteries
with their branches in colorectal cancer surgery, clarified and illustrated with virtual and physical 3D models.
The splenic
flexure is situated in-between two vascular areas irrigated from the middle
colic artery (MCA) and from the inferior mesenteric artery (IMA). The aim of
my research is to explore the impact of the MCA bifurcation, the presence of the
accessory middle colic artery (aMCA), the 3-dimensional relationship between
the two vascular areas and the pattern of the inferior mesenteric vein (IMV)
confluence.
The 3D relationship between
the MCA origin and the IMA origin is called
"the mesenteric inter-arterial stair"
the MCA origin and the IMA origin is called
"the mesenteric inter-arterial stair"
We are combining the use of by 3D virtual
reconstructions and 3D printed vascular models to understand the vascular
anatomy focusing on the anatomical understanding og the radical mesenterectomy
for the splenic flexure cancer.
The central vascular dissection of the MCA is difficult, maybe more than the central vascular dissection of the ileocolic artery. The variable anatomy in this area makes the use of 3D reconstructions or 3D models especially useful.
